Title: [OT] unofficial MinGW GDB gdb with python released
Post by: ollydbg on October 08, 2009, 08:21:52 am
Steps to build  gdb under MinGW+MSYS can be seen in the wiki: build_gdb_msys_en (http://code.google.com/p/qp-gcc/wiki/build_gdb_msys_en)
Steps to use gdb's python pretty printers and Codeblocks related setup can be seen in the wiki: GDB Pretty printer introduction and setup (http://code.google.com/p/qp-gcc/wiki/GDB)

You must install Python 2.7.5 release 32bit version on your system, as my build was linked to this python release.

2016-01-30
New release, the pre-build binary is gdb2016-01-30.zip (http://sourceforge.net/projects/gdbmingw/files/gdb2016-01-30.zip/download) and the patches are gdb2016-01-30patches.zip (http://sourceforge.net/projects/gdbmingw/files/gdb2016-01-30patches.zip/download), it fix some bugs which does not exists in 2014-05-23 version, such as this one: 17659 [win32] GDB failed to get dll names when handling LOAD_DLL_DEBUG_EVENT event (https://sourceware.org/bugzilla/show_bug.cgi?id=17659). And the binary is build with G++ compiler. As you know, GDB is migrating to C++.

2014-05-23
gdb2014-05-23.zip (http://sourceforge.net/projects/gdbmingw/files/gdb2014-05-23.zip/download) with patches against GDB GIT HEAD (http://sourceforge.net/projects/gdbmingw/files/gdb2014-05-23patches.zip/download) released. The main change in my patches from 2014-01-14 is that is fix a Bug 15806 Some fields in async MI events get escaped twice (https://sourceware.org/bugzilla/show_bug.cgi?id=15806).
2014-01-14
A new release with binary achieve gdb2014-01-14.zip (http://sourceforge.net/projects/gdbmingw/files/gdb2014-01-14.zip/download) and patches against gdb git head gdb2014-01-14patches.zip (http://sourceforge.net/projects/gdbmingw/files/gdb2014-01-14patches.zip/download). The main change from 2013-10-09 release is that I remove my workaround patch for GDB bug #12127, since I think it was fixed in the GDB main stream, see some descriptions in Comment 6 (https://sourceware.org/bugzilla/show_bug.cgi?id=12127#c6).
2013-10-09
New release for GDB, the binary achieve is in gdb2013-10-09.zip (http://sourceforge.net/projects/gdbmingw/files/gdb2013-10-09.zip/download), the patches against GDB cvs 2013-10-04 is in gdb2013-10-09patches.zip (http://sourceforge.net/projects/gdbmingw/files/gdb2013-10-09patches.zip/download), note I now use git to generate a serial patches, you can either apply them one by one manually, or by "git am" command.
MinGW GCC 4.7.0 and later has thiscall calling convention for C++ class member function, but GDB can not handle this correctly, see details in: FYI: GDB has a big bug to support MinGW GCC (4.7.x and later) (http://forums.codeblocks.org/index.php/topic,18403.0.html), my release fixes this bug by automatically detect the version of gcc which build the debugee, and fetch the correct calling convention in GDB. All the binaries are build from MSYS + mingw-builds-x32-4.8.1-posix-dwarf-rev5 with statically link to iconv, expat, zlib librares.

2013-06-08
New release for GDB cvs 2013-06-08, now I have a new site for download in gdbmingw (http://sourceforge.net/projects/gdbmingw/), and the binary achieve is: gdb2013-06-08.7z (http://sourceforge.net/projects/gdbmingw/files/gdb2013-06-08.7z/download) and the patch is gdb2013-06-08.7z (http://sourceforge.net/projects/gdbmingw/files/gdb2013-06-08.7z/download). This patch is quite small, I only try to fix two issues, one issue is the crash problem when GDB try to show an un-initialzed local variable, see Bug 12127 gdb with python support still get crash on showing uninitialized local variables (http://sourceware.org/bugzilla/show_bug.cgi?id=12127), you set run the command "set print elements xxx", the xxx is a reasonable number. The other issue it the performance regression workaround, see Bug 15412 Performance regression in "info {func,var,types} foo" (mostly info types). (http://sourceware.org/bugzilla/show_bug.cgi?id=15412).  The binaries is build from PCX's MinGW 4.7.3 suite (with an updated libmsvcrt.a to fix an missing export function issue).

2013-02-04
gdb2013-02-04.zip (http://code.google.com/p/qp-gcc/downloads/detail?name=gdb2013-02-04.zip&can=2&q=)with patch gdb2013-02-04.patch (http://code.google.com/p/qp-gcc/downloads/detail?name=gdb2013-02-04.patch&can=2&q=), note the change file name display patch was in cvs trunk now, so you can use the command below to alter the filename display format, either "relative", "basename" or "absolute". (note, the word "backtrace" was removed in the command compared to 2012-05-22 release.
Code: [Select]
set filename-display absolute

2012-12-16
gdb cvs 2012-12-15 (http://qp-gcc.googlecode.com/files/gdb2012-12-15.zip) using the patch 2012-12-15.patch (http://qp-gcc.googlecode.com/files/2012-12-15.patch)

2012-08-19
gdb2012-08-17.zip (http://code.google.com/p/qp-gcc/downloads/detail?name=gdb2012-08-17.zip&can=2&q=) build using the patch 2012-08-17.patch (http://code.google.com/p/qp-gcc/downloads/detail?name=2012-08-17.patch&can=2&q=) against gdb cvs head.

2012-05-22
gdb2012-05-22 (http://qp-gcc.googlecode.com/files/gdb2012-05-22.zip)now build from xunxun's mingw gcc 32bit 4.6.3 release.
Here is the total patch file patch against gdb cvs (http://qp-gcc.googlecode.com/files/2012-05-22.patch).
It is linked to python 2.7.3 library, so you need to have python 2.7.3 installed on your system.
To see the full file path on the backtrace command, you need to run the command:
Code: [Select]
set backtrace filename-display absolute
See: Jan Kratochvil - Re: [patch] GDB 7.2: new feature for "backtrace" that cuts path to file (http://sourceware.org/ml/gdb-patches/2012-04/msg00106.html) for more details and other options.


2012-02-16
gdb2012-02-16.7z (http://qp-gcc.googlecode.com/files/gdb2012-02-16.7z) now build from xunxun's gcc 4.6.3 release (http://pcxprj.googlecode.com/files/MinGW64CRT_gcc4.6.3.20120221_sse2static_win32.7z).
The total patch file against vanilla gdb cvs(I use gdb's read only git clone) can be found in: gdb2012-02-16.patch (http://qp-gcc.googlecode.com/files/gdb2012-02-16.patch)
I find a regression about showing full file name in bt command since 2011-12-12, because the patch: iam ahal - Re: [patch] GDB 7.2: new feature for "backtrace" that cuts path to file (http://sourceware.org/ml/gdb-patches/2011-12/msg00100.html) does not fully solve the problem: show full paths on backtrace (http://forums.codeblocks.org/index.php/topic,14792.msg99575.html#msg99575).

This release fix the regression and works OK now.

Note: this issue is only related to debug a dll (which build with relative file source paths) under c::b, because c::b need an full name to open a source file, see more details: show full paths on backtrace (http://forums.codeblocks.org/index.php/topic,14792.msg99575.html#msg99575).

HAPPY CHINESE NEW YEAR (Dragon year is coming)
The new pre-build binary package can be found in gdb2012-01-19.7z (http://qp-gcc.googlecode.com/files/gdb2012-01-19.7z), it is gdb's latest cvs version with my patch (http://qp-gcc.googlecode.com/files/gdb2012-01-19.patch) applied.
I remove the hard-coded relocated code, because gdb can relocate correctly, see: Doug Evans - Re: Possible fix for mingw32 directory relocation problems (http://sourceware.org/ml/gdb-patches/2012-01/msg00676.html) related discussion for more details. The other parts of the patch include: work around the crash problem of local variable print, adjust some minor file paths of call-stack print.


2011-11-08 release
Pre-build binary can be found in gdb2011-11-08cvs.7z (http://qp-gcc.googlecode.com/files/gdb2011-11-08cvs.7z)

GDB built with python support, you need to install python 2.7.2 in your system. This build include some patches to handle file paths problem under Windows system.

A patch to accelerate the file path comparasion, see: asmwarrior - Re: [RFC] Avoid calling gdb_realpath if basenames are different (http://sourceware.org/ml/gdb-patches/2011-11/msg00141.html) and Re: configure file to debug codecompletion plugin (http://forums.codeblocks.org/index.php/topic,12951.msg104087.html#msg104087)

Watchpoint can be used in both gdb.exe and gdbserver.exe, see: brobecke - src/gdb/gdbserver ChangeLog win32-i386-low.c (http://sourceware.org/ml/gdb-cvs/2011-11/msg00039.html)

The total diff file to the gdb cvs head source can be found in: gdb2011-11-08cvs.diff (http://qp-gcc.googlecode.com/files/gdb2011-11-08cvs.diff)

2011-10-09
Update to the latest gdb cvs, and the patches I used was also contains in the achieve. see: gdb2011-10-09cvs.zip (http://code.google.com/p/qp-gcc/downloads/detail?name=gdb2011-10-09cvs.zip&can=2&q=), this release was build with python 2.7.2, expat cvs library(static), iconv cvs library(static). I build it with TDM GCC 4.5.2sjlj, and with -O2 enabled. (It should be faster than my previous releases).
Note: I found that this revision has some tiny bugs. E.g. when step, it will complain some memory reading errors, so I still suggest using the 2011-08-10 version until I update to a new revision.

2011-08-10
To solve the problem I stated in load gdb's own python script support (http://forums.codeblocks.org/index.php/topic,15104.msg101072.html#msg101072), I have hack the gdb's data search directory. The full patch was gdb2011-08-08.patch (http://code.google.com/p/qp-gcc/downloads/detail?name=gdb2011-08-08.patch&can=2&q=), You need to extract this package to your installed MinGW folder, when starting gdb, the python script under "YourMinGW/share/gdb/python/gdb" will be automatically loaded. Thus, you can qurey pretty-printer information by the command: "info pretty-printer". such as the log below:
Quote
>>>>>>cb_gdb:

global pretty-printers:
  libstdc++-v6
    __gnu_cxx::_Slist_iterator
   ......

The package can be download from GDB2011-08-10cvs.7z (http://code.google.com/p/qp-gcc/downloads/detail?name=GDB2011-08-10cvs.7z&can=2&q=).

2011-08-04
NOTE: This version has some issue on backtrace command, I removed the package on Google Host site, and Please use a previous version instead until I fix this issue. Sorry for the inconvenience.(This issue is fixed)
GDB7.3.50.20110804-cvs.7z build from gdb git master source, and with the patches to fix windows breakpoint and other problems, see:

This version I build with static expat library, and you should have python 2.7.x installed on your system.
You can download the binaries from: Download (http://qp-gcc.googlecode.com/files/GDB7.3.50.20110804-cvs.7z), Have Fun!!!

2011-06-06
gdb-7.3.50.20110604 build from gdb git source.
build against python 2.7.1, expat cvs.
As the latest gdb/linespec.c has bugs under Windows, so I use an old version of linespec.c to solve the problem.
see: http://sourceware.org/ml/gdb/2011-06/msg00024.html
This package also contains all the python related script libraries and dlls, so install a separate python is not necessary.
The download link is: gdb-7.3.50.20110604.7z (http://qp-gcc.googlecode.com/files/gdb-7.3.50.20110604.7z)

since the official gdb 7.2 is released, then Loaden has build this one, he just build it from the official gdb 7.2 source(no extra patches is used). It is linked against expat static library, also python pretty script is enabled. (the package has python script for std library and wxwidgets). You can download it from: gdb-7.2.7z (http://qp-gcc.googlecode.com/files/gdb-7.2.7z)
Thanks loaden for the build. for How to use GDB with python under Codeblocks, see:

2010-07-09
The new gdb file has uploaded to gdb-7.2.50.20100708-cvs.7z (http://qp-gcc.googlecode.com/files/gdb-7.2.50.20100708-cvs.7z), it is now linked against python 2.7. Many Thanks to loaden for the build!!!

2010-06-24
The new gdb file has uploaded to http://qp-gcc.googlecode.com/files/gdb7.1.50.20100623cvs.7z

2010-05-22:
Hi, all. I have successfully built the mingw gdb 7.1.50 snapshot from the source gdb-7.1.50.20100521. tar.bz2 (http://ftp://sourceware.org/pub/gdb/snapshots/current/gdb-7.1.50.20100521.tar.bz2) link against expat static library (build under Loaden's mingw 4.4.4 and Msys). You can download it from gdb-7.1.50.20100521.7z (http://qp-gcc.googlecode.com/files/gdb-7.1.50.20100521.7z)
It is just runs fast as gdb 7.0.1.
As you know, the 7.1 version has some problems(time delay when showing wxString), this gdb 7.1.50 don't have this problem.
Have a try!!

For older version of GDB
GDB  MinGW GDB 7.0.1 (http://sourceforge.net/projects/mingw/files/GNU%20Source-Level%20Debugger/GDB-7.0.1/gdb-7.0.1-mingw32-bin.tar.gz/download), this 7.0.1 version is link to dynamic expat library, so, you need a expat dll (see below). you will need libexpat-2.0.1-1-mingw32-dll-1.tar.gz, available here:libexpat-2.0.1-1-mingw32-dll (http://sourceforge.net/projects/mingw/files/MinGW%20expat/expat-2.0.1-1/libexpat-2.0.1-1-mingw32-dll-1.tar.gz/download)

I just notice that under GDB 7.0, the loading time of a debuggee (I'm debugging codeblocks under codeblocks) is only 10 seconds.

But under gdb 6.8.3, it's about 30 seconds.

So, it's much faster. :D

Edit

I'm sorry, that I think the TDM-GCC 4.4.0 and GDB7.0 has some conflict. because, in GDB 7.0, I can't set breakpoint anymore.

see the debug log:

Code: [Select]

Is this only the output, or does it really not break there ?

It's the normal output you get if you set a bp in not yet loaded libraries and it looks exactly the same as with gdb 6.8.50 on linux, and here it works.

I just build a debian-package of the gdb-sources.
I did not patch anything, just plain sources.

I installed and it works as expected.
Same behaviour than with 6.8.50, as far as I can see. Just one bp (in nativeparser.cpp:1422), some steps, step out, watch some variables, everything seems to work fine.

Here is the full output of the debug log.

It seems the Mingw gdb7.0 still can't reach the breakpoint.

Hi ollydbg,

I had a similar problem with ARM gdb that I build myself under windows. In the gdb sources there was a bug in getting the relative path for setting breakpoints. After putting the following code in the file util.c it worked also under windows. The strange thing is that the binary version of gdb 6.8 worked without changes for x86.

Code: [Select]
#if !defined(HAVE_REALPATH)
#if defined (_WIN32) || defined(__MINGW32__)
# define WIN32_LEAN_AND_MEAN
# include <windows.h> /* for GetFullPathName */
# endif
#endif
....

char *
gdb_realpath (const char *filename)
{
...
  #if !defined(HAVE_REALPATH)
   # if defined (_WIN32) || defined(__MINGW32__)
   /* The MS Windows method. If we don't have realpath, we assume we
   don't have symlinks and just canonicalize to a Windows absolute
   path. GetFullPath converts ../ and ./ in relative paths to
   absolute paths, filling in current drive if one is not given
   or using the current directory of a specified drive (eg, "E:foo").
   It also converts all forward slashes to back slashes. */
   {
   char buf[MAX_PATH];
   char *basename;
   DWORD len = GetFullPathName (filename, MAX_PATH, buf, &basename);
   if (len == 0 || len > MAX_PATH - 1)
   return strdup (filename);
   else
   {
   return strdup (buf);
   }
   }
#endif
#endif

Thanks.

I will report this issue on the MinGW Mail list.

Also, another question is:
How can I build a gdb.exe, Is it easy to do?
for now, I can download the source code from
http://sourceforge.net/projects/mingw/files/GNU%20Source-Level%20Debugger/GDB-7.0/gdb-7.0-mingw32-src.tar.gz/download

Thanks again!

Excellent!
Now I can debug again using Code::Blocks.
I was not able to do this with previous GDB versions for MinGW since I
switched to 4.4.0.
Thanks.

String thing :(, it seems this guy can debug under GDB 7.0. and can't debug under GDB 6.8.

It works for me. (TDM-GCC 4.4.0 and GDB 7.0 from the above link)

However I also noticed something strange.

Tooltipped during debugging on an std::string (local variable).  [the ..... mean there is more stuff there]
Code: [Select]
ContinueDebugEvent .......
gdb : kernel event for pid= ..... ... code=EXCEPTION_DEBUG_EVENT
ContinueDebugEvent ....
gdb : kernel event for pid= ..... ... code=EXCEPTION_DEBUG_EVENT
"Group"
Notice the "Group" at the end, the correct value of the string.

With another string it is ok.

Hello, killerbot, if you just create a simple console project, then it works.
But could you please test by setting a breakpoint in the codeblocks' source code? this case, it didn't work here.

Here is the main step:

1, install TDM-MinGW 4.4.0
2, unzip the GDB.exe 7.0 binary package, and paste to the TDM-MinGW folder.(some files will be overwritten)
3, I have try both  CB_trunk, CB_debuger_branch, CB_nightly_build version.
4, You open the codeblocks.cbp file, and set a breakpoint under any cpp file, and start debugging.


the result is:
the breakpoint can't be set correctly, and the debugee keeps running...with no break.

 :(

I can see some "Function not defined" and "Breakpoint pending" messages, but I don't know what they mean.

This problem happens on WinXP Pro SP2.
Also one of my friends has the same problem.
I'd like trying with new gdb 7.0, but I don't know where to find a binary release, or how to compile it by myself from the sources.

If you install the TDM-MinGW 4.4.0 package( this has already include a gdb.exe 6.8.3), it should works quite well.

Works fine, here.
I set a BP in C::B's "main" function -> stops.
While stopped I set a BP in a sub-method that'll be called certainly and hit continue -> stops.

For me all is OK?! (Using TDM 4.4.0, GDB 7.0 and C::B's debugger branch.)

BTW: Try really removing TDM before installing it freshly (from the single packages). Cause GDB7 has some files in different folders now.

I've already installed the TDM-MinGW 4.4.0 package (tdm-mingw-1.905.0-4.4.0-2.exe file).

I did some tests with the "Hello World" example: the debugger stops at breakpoint only if the project files and the debugger are in the same unit (both in C: disk), and the path doesn't contain spaces. If I move the project to another unit (Z:\), or to a path with spaces (for example  \Documents and Settings\...) the debugger doesn't stop anymore at the breakpoint.

Thanks for the hint. I have totally uninstall and remove the TDM.

Then, I just reinstall TDM , and upzip the GDB7.0 package(Note, GDB7.0 has four folders, so, I just let the GDB7.0's file overwrite the TDM's)

But, I still get the same error, things like:

Yes, I have read that, I also had tested that method.
I just set a breakpoint in the main function, which is in

F:\cb_svn\src\tools\ConsoleRunner\main.cpp

But it still can't stops there. :(

Harhar... :lol:

Well... try a BP src/src/main.cpp e.g. in the CreateIDE() method.

The main.cpp you pointed to will not work, obviously, as this is only the console_runner executable, not C::B itself. ;-)

My god... Big mistake...
Thanks, I will try this tomorrow, it's time to go to bed now. :wink:

Edit


But for gdb.exe 6.8.3, I don't need to  firstly set a breakpoint in the main(), I can directly set a breakpoint any where(for example tokenizer.cpp). :D

The same applied for GDB7. "main" was just an example. ;-) Good night! :P

Setting breakpoing at src\src\main.cpp, CreateIDE() works.
When the breakpoint above hitted. I still can't set breakpoint in tokenizer.cpp DoGetToken(). :(

Title: Re: [OT] MinGW GDB 7.0 is released
Post by: theOcelot on October 09, 2009, 07:30:13 pm
It's not working for me. I've always had trouble with hitting breakpoints in headers. Here's a few more datapoints to work with:

I'm on Windows Vista, the official MinGW G++ 4.4.0, and CB 8.02. I started a fresh, C++, CB console project, and added the following file, named "tester1.h":
Code: [Select]
#ifndef TESTER1_H
#define TESTER1_H

#include <iostream>

inline void function(){
    std::cout << "in function()" << std::endl;
}

struct Foo{
    Foo(){
        std::cout << "constructing Foo" << std::endl;
    }
    void bar(){
        std::cout << "Foo::bar" << std::endl;
    }
};

#endif

Then in main .cpp:
Code: [Select]
int main()
{
    cout << "Hello world!" << endl;
    Foo foo;
    function();
    foo.bar();
    return 0;
}

I set breakpoints on all the output lines in tester1.h, and on the return 0. Only the latter was hit, with either GDB 6.8 or 7.0. Same results when I named the header tester.h, in case the number in the filename was screwing things up. There path to my project is C:\Users\Fleenor\Projects\DebugTest, no spaces or anything irregular. Mingw is C:\MinGW.

Here is my debug log with GDB 7.0, tester1.h:

The interesting part of course is where it still says "No source file named C:/Users/Fleenor/Projects/DebugTest/tester1.h." I wonder if it could be something to do with the different slash types, but it seems like that would have been fixed a long time ago.

I don't really want to do anything to further confuse my installation, but would TDM help me? Is the only way to know to try? I'll attach my project in 7z format, if anyone wants to see if they can reproduce my behavior, or show non-reproducibility on their system.

@theOcelot

I test your code.

Q:Is breakpoint in a header file works?

A: Win XP TDM-MinGW 4.4.1  GDB 6.8.3 works

A: Win XP TDM-MinGW 4.4.1  GDB 7.0    works


By the way:
Does other guys try setting a breakpoint in a C::B's plugin source, like plugins\codecompletion\parser\tokenizer.cpp. It seems the breakpoints don't work there. The problem is quite the same:

Code: [Select]
>>>>>>cb_gdb:
> break "F:/cb_svn/src/plugins/codecompletion/parser/tokenizer.cpp:591"
No source file named F:/cb_svn/src/plugins/codecompletion/parser/tokenizer.cpp.
Breakpoint 4 ("F:/cb_svn/src/plugins/codecompletion/parser/tokenizer.cpp:591) pending.

Ha! Victory! I hand-compiled main.cpp into main.o on the command line, using relative paths with forward slashes instead of absolute paths with backslashes, as in Bob Fletcher's bug report (http://"http://sourceforge.net/tracker/index.php?func=detail&aid=2145427&group_id=200665&atid=974439"). Once CB linked it, it worked, and all three header breakpoints were hit.

The nightly build has the same behavior, passing paths using backslashes, so the problem didn't go away when I switched. Maybe it will let me ctrl-shift-F9 to compile just one file without crashing again, in which case it will have been worth it anyway.
Title: Re: [OT] MinGW GDB 7.0 is released
Post by: ollydbg on October 10, 2009, 09:22:41 am
I think I find the reason why I can't debug C::B under GDB 7.0 (Win XP TDM-MinGW 4.4.1 )

Here is my steps:
1, clear all the breakpoints.
2, I start debugging.
3, the debuggee started
4, but I fond that GDB.exe hungs, because I can't manually send the debug command in the "debug" panel. There's no response after I hit enter button.

 :(

Any ideas?

Edit
I just do another test:

1, clear all the breakpoints.
2, I start debugging.
3, the debuggee started
4, I click on the "stop debugger" button, but it seems the debugger can't be paused.

Here is the log:

Code: [Select]
Debugger name and version: GNU gdb (GDB) 7.0
Trying to pause the running process...

So, I know why I can't set breakpoint when debugging, you can see the code below:

Code: [Select]
bool DebuggerGDB::AddBreakpoint(const wxString& file, int line)
{
    const bool debuggerIsRunning = !IsStopped();
    if (debuggerIsRunning)
    {
        Break();
    }
    m_State.AddBreakpoint(file, line, false);
    if (m_pBreakpointsWindow)
    {
        m_pBreakpointsWindow->Refresh();
    }
    if (debuggerIsRunning)
    {
        Continue();
    }
    return true;
} // end of AddBreakpoint

But it seems the "Break();"  function can not be executed correctly( gdb is still running or gdb hangs ), then certainly I can't set the following breakpoints.

In the code:

{
    // m_Process is PipedProcess I/O; m_Pid is debugger pid
    if (m_pProcess && m_Pid && !IsStopped())
    {
        long pid = m_State.GetDriver()->GetChildPID();
        if (pid <= 0)
            pid = m_Pid; // try poking gdb directly
    #ifndef __WXMSW__
        // non-windows gdb can interrupt the running process. yay!
        if (pid <= 0) // look out for the "fake" PIDs (killall)
            cbMessageBox(_("Unable to stop the debug process!"), _("Error"), wxOK | wxICON_WARNING);
        else
            wxKill(pid, wxSIGINT);
    #else
        // windows gdb can interrupt the running process too. yay!
        bool done = false;
        if (DebugBreakProcessFunc && pid > 0)
        {
            Log(_("Trying to pause the running process..."));
            HANDLE proc = OpenProcess(PROCESS_ALL_ACCESS, FALSE, (DWORD)pid);
            if (proc)
            {
                DebugBreakProcessFunc(proc); // yay!
                CloseHandle(proc);
                done = true;
            }
            else
                Log(_("Failed."));
        }
    #endif
        // Notify debugger plugins for end of debug session
        PluginManager *plm = Manager::Get()->GetPluginManager();
        CodeBlocksEvent evt(cbEVT_DEBUGGER_PAUSED);
        plm->NotifyPlugins(evt);
}
}

The main task is call the DebugBreakProcessFunc function. Which is defined by :

Code: [Select]
   kernelLib = LoadLibrary(TEXT("kernel32.dll"));
    if (kernelLib)
        DebugBreakProcessFunc = (DebugBreakProcessApiCall)GetProcAddress(kernelLib, "DebugBreakProcess");
    #endif
}

Make the most sense, since it works cross platform and uses the GDB internals as opposed to relying on a win32api call that only exists in XP and above?

I personally think this command make no sense, because when the debuggee is running, GDB.exe  can't accept any command.

Hi, all, I just find some more issue of gdb.exe 7.0, it seems that gdb.exe 7.0 can't set breakpoint in a DLL's source file, but gdb.exe 6.8.3 can.

Here is the test project, it contains two target, one is a exe, and one is a dll, then, the exe will call a function in the dll.

You can set breakpoints in both exe and dll, but for gdb.exe 7.0, only breakpoints in exe file can be reached.

So, this means gdb 7.0 treats dll file badly. :(

It works for me. (TDM-GCC 4.4.0 and GDB 7.0 from the above link)

However I also noticed something strange.

Tooltipped during debugging on an std::string (local variable).  [the ..... mean there is more stuff there]
Code: [Select]
ContinueDebugEvent .......
gdb : kernel event for pid= ..... ... code=EXCEPTION_DEBUG_EVENT
ContinueDebugEvent ....
gdb : kernel event for pid= ..... ... code=EXCEPTION_DEBUG_EVENT
"Group"
Notice the "Group" at the end, the correct value of the string.

With another string it is ok.

The cause for the flood of (visible) ContinueDebugEvent's is that the gdb startline has changed from GNU gdb x.x.x to GNU gdb (GDB) x.x.x.
The additional (GDB) breaks our code to determine the gdb major- and minor-version and that breaks the code that determines the child-pid's of gdb.
After fetching the child-pid we no longer parse lines that start with ContinueDebugEvent.

I think we could use a regex here to filter out the version number, to avoid such problems inth future.

here is patch that can do that:
Code: [Select]
Index: gdb_driver.cpp
===================================================================
--- gdb_driver.cpp (Revision 5861)
+++ gdb_driver.cpp (Arbeitskopie)
@@ -861,7 +861,13 @@
             // it's the gdb banner. Just display the version and "eat" the rest
             m_pDBG->Log(_("Debugger name and version: ") + lines[i]);
             // keep major and minor version numbers handy
-            wxString major = lines[i].Right(lines[i].Length() - 8);
+            wxRegEx re(_T("([0-9.]+)"));
+            if (!re.Matches(lines[i]))
+            {
+                m_pDBG->Log(_T("Unable to determine the version of gdb"));
+                break;
+            }
+            wxString major = re.GetMatch(lines[i],0);
             wxString minor = major;
             major = major.BeforeFirst(_T('.')); // 6.3.2 -> 6
             minor = minor.AfterFirst(_T('.')); // 6.3.2 -> 3.2

It does not fix the main problem (can not set breakpoints in some files and libs) of course, but that appears to be a gdb-issue.

I managed to find a little time to test debugging a DLL and I was able
to do so with GDB.  Here's the steps I ran:

1.  Compile both the 'exe' and 'dll' with debug symbols
2.  Run 'gdb'
3.  From the (gdb) prompt type 'file [library name].dll'
4.  From the (gdb) prompt type 'break [library source file].cpp:[line number]'
5.  From the (gdb) prompt type 'exec-file [executable name].exe'
6.  From the (gdb) prompt type 'run'

As expected, gdb stopped at the line number in the library source file.

So from a GDB standpoint, it is behaving as expected and it can set
breakpoints on DLLs and actually hit them.  I'll grab the latest C::B
nightly Tuesday (unfortunately I won't have the time tomorrow to test
it) and see how it goes about debugging a library.

Cheers!

Chris


So, it seems in the now gdb 7.0, we should manually send command 'file [library name].dll' . I think currently, this haven't done in the C::B's debugger plugin.

Hi ollydbg,

I had a similar problem with ARM gdb that I build myself under windows. In the gdb sources there was a bug in getting the relative path for setting breakpoints. After putting the following code in the file util.c it worked also under windows. The strange thing is that the binary version of gdb 6.8 worked without changes for x86.


hello, the source file was "utils.c" not "util.c"  :D

Also, I have successfully built the gdb.exe under TDM-GCC 4.4.1 and MSYS system. :D

I just find more bugs of GDB.

Follow the steps

 Here's the steps I ran:

1.  Compile both the 'exe' and 'dll' with debug symbols
2.  Run 'gdb'
3.  From the (gdb) prompt type 'file [library name].dll'
4.  From the (gdb) prompt type 'break [library source file].cpp:[line number]'
5.  From the (gdb) prompt type 'exec-file [executable name].exe'
6.  From the (gdb) prompt type 'run'


I still can't load the dll file. here is the Debug log:

Hi, all, from the MinGW mail list, the new updated GDB.exe 7.02 is released, and the "setting bp issue on dll" is gone.

I've uploaded a new GDB 7.0 release with XML parsing enabled via
linking to libexpat.  It's available here:

http://sourceforge.net/projects/mingw/files/GNU%20Source-Level%20Debugger/GDB-7.0/gdb-7.0-2-mingw32-bin.tar.gz/download

For this release you will need libexpat-2.0.1-1-mingw32-dll-1.tar.gz,
available here:

http://sourceforge.net/projects/mingw/files/MinGW%20expat/expat-2.0.1-1/libexpat-2.0.1-1-mingw32-dll-1.tar.gz/download

As before, please report any issues to the MinGW-users list.

I've dug in to this and managed to add a break point in a DLL using
C::B.  I built my DLL with debug symbols and set a breakpoint in the
source for the DLL.  I then selected and executable that calls the DLL
and hit the 'Debug / Continue' button and it hit the DLL breakpoint.

I'm using a self compiled (using the official MinGW GCC 4.4.0) C::B
from svn trunk, GDB 7.0-2 and a DLL and app compiled with the official
MinGW GCC.

Cheers!

Chris

Now, I have confirm that the new gdb.exe 7.02 and TDM GCC 4.4.1 can works perfectly!!!

And if you want to build a C::B that support the new GDB 7.0, you should apply this patch by jens.

It's an irc service (irc.freenode.net).  Alternately, perhaps follow-up on the GDB mailing list.  I'll try to recreate the issue later today and follow up accordingly.  When I do a backtrace using using GDB command line I don't see these messages.

hello, thanks.
I just test a simple exe and dll project, then I don't see any such warnings.

But these warning is exist when I'm debugging the C::B's plugin dll. :D, so, I'm not sure there is the something wrong with C::B plugin or others. :(

I see the same warnings with different hex values when debugging Qt4-based app with TDM-GCC+GDB7+Eclipse+CDT+Qt eclipse integration. And I don't see them when I revert back to GDB 6.8 that comes in the TDM's installer. So I think it's not a CB-related problem (at least not CB-specific one).

At least it works on my test case of EXE and DLL project.

So, what's the problem? From the debugger log, it seems the GDB exit abnormally? Could you supply a test case?
At least it works on my test case of EXE and DLL project.

1, New a  "SDL project" (by c::b's project template), named the project "SDL_WinMM_GDBTest" .

2, Add a new target named "DLL_Debug", and add the complie option -D_BUILD_DLL_.

3, modify the main.cpp, and build the "DLL_Debug" target.
Code: [Select]
#if defined(_BUILD_DLL_)
int dll_main( int argc, char** argv )
#else
int main ( int argc, char** argv )
#endif
{
   ...
}

4, Create a C++ Console Project (by c::b's project template) , named "CallSDL_WinMM_GDBTest".

5, Add  a new  "Virtual target" to "CallSDL_WinMM_GDBTest" which alials is "DLL_Debug" and "Build targets contained": Debug.

6, the main.cpp for "CallSDL_WinMM..."
Quote
#include <iostream>
using namespace std;

int dll_main( int argc, char** argv );
int main(int argc, char** argv )
{
    dll_main(argc, argv);
   
    return 0;
}

7, Add two lib to CallDLL_WinMM_GDBTest's "Link libraries "
   SDL_WinMM_GDBTest.dll
   SDL

8, then add the linke search path...

9, build CallDLL_Win_GDBTest.exe , run it. It looks everythink OK, now.

10, Prerss F8, then the error message occurrences in Debugger(debug) log panel :
   
Code: [Select]

1. download the sdl source here (http://www.libsdl.org/download-1.2.php) and unzip it.
2. starut msys , cd the sdl source dir
3. ./configure  -> make -> make install
4. in c::b, add a new global var : sdl
   copy include to $sdl.include
   copy /local/bin and local/lib  to $sdl.lib   

EDIT here is the test project package : sdl_gdb_dll_test (http://www.d2school.com/temp/sdl_dll_test.7z)

thanks you!

Just a reminder:
In the MinGW mail list:

Quote
From: Chris Sutcliffe <[email protected]>
Subject: GDB 7.0.1
Newsgroups: gmane.comp.gnu.mingw.user
Date: 2010-01-07 19:07:37 GMT (5 days, 10 hours and 11 minutes ago)

I've released GDB 7.0.1 for MinGW.  This binary is built from vanilla
GNU GDB sources.

http://sourceforge.net/projects/mingw/files/GNU%20Source-Level%20Debugger/GDB-7.0.1/gdb-7.0.1-mingw32-bin.tar.gz/download

This time around I've packaged it without the static libraries
(libbfd, libopcodes, libiberty) so as to not conflict with binutils.

Please direct any questions / comments to this mailing list.

Enjoy!

Chris


one problem still exist. too many gdb warning when debugging C::B (http://forums.codeblocks.org/index.php/topic,11301.msg77274.html#msg77274)
Title: Re: [OT] MinGW GDB 7.0.1 is released in 2010 01 07
Post by: ollydbg on January 13, 2010, 06:59:14 am
To reproduce this bug. you can do like this:

1, open codeblocks.cbp in C::B.
2, build the whole project.
3, place a break point in the line 488 of MainFrame::MainFrame() function (in file: F:\cb_svn\src\src\main.cpp)
4. press the "debug" button on the toolbar.
5, when the debugger hit the breakpoint, you need to open the "call stack" dialog.
6, from the "debug log" panel, you can see a lot of warnings.(You need to select: Menu->settings->Compiler and debugger settings-> debugger settings. and select "display debugger's log).

Any comments or suggestions? thanks.

Python scripting is not enabled.  To be honest I haven't looked in to adding it (I don't use it myself), but I'll take a look at what's involved in adding the support this coming week.

Title: Debug Error Message
Post by: JZ on February 09, 2010, 06:02:45 am
I'm trying to run the GDB debugger for on a Windows platform the first time on a C program and I get the following error message.  

"The debugger executable is not set.  To set it, go to "Settings/Compiler and debugger", switch to the "Programs" tab, and select the debugger program."  

I looked on the Settings page and don't see a "Programs" tab.  What am I missing?

Do I need to separately install GDB?  If so, is there a how to link or can someone point me in the right direction?

Title: Re: Debug Error Message

Do I need to separately install GDB?

Depends on your gcc installation.
But with this error-message the answer is most likely yes.
For a download see the link in one of the previous posts.

To check whether it is set up correctly, look into "Settings -> Compiler and debugger -> Global compiler settings -> [your compiler] -> Toolchain executables" .

I find the 7.0.50 version of gdb didn't work correctly.
when I try to view a wxString value in Codeblocks, it takes a lot of time.
Code: [Select]
> whatis m_Buffer
type = wxString
>>>>>>cb_gdb:
> output /c m_Buffer.m_pchData[0]@((wxStringData*)m_Buffer.m_pchData - 1)->nDataLength
{116 't', 101 'e', 115 's', 116 't', 46 '.', 99 'c', 112 'p', 112 'p'}>>>>>>cb_gdb:


When the codeblocks send the command : output xxxxx to gdb, it takes several (more than 10s) to return the string value.

What happens, if you debug from commandline ?

Or if you put the command in the "Command:" text-control and execute it (without running of C::B's gdb-parser) ?

Do you use any debugger related patches or clean sources from trunk.


I just tested it with gdb 7.0.50 as cross-debugger for a wxMSW app on my linux-box and the output occurs immediately after the command is sent to gdb (from inside the program or from the textcontrol).

One more question: what do you try to debug ?

I switched to gdb 6.80 on my linux-box, because all 7.0 versions do not work correctly with parts of the C::B sources (at least not when compiled with wxWidgets debug version), 6.80 works fine.

Thanks for the reply.
I use the debugger which was release http://sourceforge.net/projects/mingw/files/GNU%20Source-Level%20Debugger/GDB-7.0.50.20100202/gdb-7.0.50.20100202-mingw32-bin.tar.gz/download (http://sourceforge.net/projects/mingw/files/GNU%20Source-Level%20Debugger/GDB-7.0.50.20100202/gdb-7.0.50.20100202-mingw32-bin.tar.gz/download)


I'm just debugging C::B( I'm watching a wxString in CodeCompletion plugin )under C::B.
I will try to create a simple wxWdigets sample code to test it again, also, I will send the command from the "direct input"( once the watches windows was open, it will send these command automatically, so I need to close the watch window when debugging )

Ok, gdb 7 works fine when I debug a simple wxWdigets created from the "project wizard" in Codeblocks, there's no time lag here.

So, the problem is, it works badly when I'm debugging some C::B's source.

That's why I switched back to 6.80 on linux.
I wanted to debug wxWidgets (due to bugs in wx-2.9 and trunk), but the debugger did not stop at my breakpoints, I got the output that says it is at line xxx and C::B believes that (yellow triangle), but in fact the debugger did not really stop.
I had this issues with gdb 7.0.1 from debian repository.

I just download the gdb snapshot from:

ftp://sourceware.org/pub/gdb/snapshots/branch/ (ftp://sourceware.org/pub/gdb/snapshots/branch/)

gdb-weekly-7.0.90.20100223.tar.bz2

And follow the steps in :

http://dev.zhourenjian.com/blog/2009/03/11/compiling-gdb-debugger-in-windows.html

Then, I build the gdb.exe myself.
 It seems 7.0.90.20100223 runs faster, and without the lag problems when showing wxString value when debugging CodeCompletion plugin.


Note
Wait, I have noticed that:
when I have three wxString variable listed in watches window, this self-built of gdb still runs slower than the 7.01 version... :(

I have build  both
branch/gdb-weekly-7.0.90.20100223.tar.bz2
and
current/gdb-7.1.50.20100223

But both work a bit slow when showing the wxString value(Even I entered the command from the command line)

For example, if m_Str is a wxString variable in CodeCompletion
Code: [Select]
output /c m_Str.m_pchData[0]@((wxStringData*)m_Str.m_pchData - 1)->nDataLength

Did you know whether there is a slow down when parsing the command input??? or there are other bugs? How can I report this bug?

@iron

Today, I found that the time delay problem may due to the Compiler conflict. I used to use TDM-GCC 4.4.1 SIJI version.

Today, I downloaded the GCC 4.4.3 compiler from Loaden's google code:
http://code.google.com/p/qp-gcc

Then, I built wxWidgets library and Codeblocks_SVN using GCC 4.4.3, and try to debug my own "parserTest" project.

Unluckily, I encountered the problem like:

Quote
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information."

Both the official mingw gdb 7.0.1 and 7.0.50 get the same error.

Luckily, I found that I can debug the "parserTest" project by gdb.exe built from the latest gdb snapshot like: current/gdb-7.1.50.20100223
Also, it showed the wxString's value quickly, and there's no time lag.


So, if someone meet these same problem as me, I can upload the self built gdb.exe.

Edit
The self-build GDB.exe still has some problems...., and the CLI response time is still a bit slower then the official 7.0.1 :(

I have another question:
I build the gdb in a very simple steps:
1, download the GDB tarball from the sourceware ftp
2, (I have MSYS and MinGW installed), I just swith to the GDBXXXX.XXX folder in MSYS command line
3,  entering this command: configure
4,  entering this command: make

So, my question is: it seems the previous version of gdb your build(offical mingw 7.0.1) was depend on the libexpat library. So, do I need to enable the expat library option?, if Yes, How can I build gdb depend on libexpat? thanks very much!

Yes, expat is required in order to debug DLLs (amongst other things).  In order to build a gdb that uses expat, you would need to build expat itself (http://expat.sourceforge.net/) and place the headers / libraries somewhere that your compiler can find them.

The expat I use is available on the MinGW project page, but since you are using a different GCC, you will need to build it yourself.  Thankfully the build process is pretty simple, just configure / make.

If you run in to any snags, let me know and I'll do my best to help you out.

one is here, from mingw
http://sourceforge.net/projects/mingw/files/MinGW%20expat/expat-2.0.1-1/expat-2.0.1-1-mingw32-src.tar.gz/download

the other is here, from expat official site
http://sourceforge.net/projects/expat/files/expat/2.0.1/expat-2.0.1.tar.gz/download

Did I need to do this:
1, download expat
2, build expat, then it generate a static library like: expat.a
3, then I copy the expat.a to the mingw library folder, and I copy the expat's header files to mingw's include header folders.
4, Then, I build the gdb

right?

You can use either.  The MinGW sources are the same as the official sources, just renamed.

Correct.  You can statically link or dynamically against expat.  You can also add '-L<path to expat> -I<path to expat>' to your CFLAGS when compiling gdb.

Thanks ironhead.

now, I have successfully build the expat library.

I use this command, suppose I would like to install to C:\ccc, in MSYS, in the expat source root

Code: [Select]
./configure -prefix=/c/ccc --enable-shared  [enter]
...
make[enter]

make install [enter]


Now, I have both dlls and headers and libraries in the C:\ccc

then I copy these files to MinGW, so, now, GCC can use these libraries.

Now, I use these command to configure GDB, suppose I'm in GDB source folder:
Code: [Select]
configure -prefix=/c/ddd -enable-shared [enter]
...
make[enter]

make install [enter]

I'm now building gdb.exe now. Am I right??? thanks.

I would like dynamiclly link to the utilitbins and expat-1.dll as you release 7.0.1. Thanks.

I have successfully built the gdb.exe from snapshot of gdb-7.1.50.20100226, but when I'm checking it's dependency, it is *not* depend on the expat-1.dll. As a result, I can't debug CodeCompletion plugin, when I'm setting a breakpoint in the DLL source, the program didn't stopped at that point.

As I found from other site, it seems the expat library is necessary to debug Windows DLL files.

So, my question is: How to configure the GDB to let it depend on the expat.dll?

Edit:

Code: [Select]
You can also add '-L<path to expat> -I<path to expat>' to your CFLAGS when compiling gdb.Since I have already copy the generated lib,headers to MinGW folder, do I still set the library path and include path?

I found in here: http://sourceware.org/ml/gdb/2010-01/msg00189.html
What does "-static" used for??

Oh, I found that I used to do the configure in the root folder(which is totally wrong!!!.....), which is in

But for correctly configuration, I need to "cd" to

Finally, I have successfully build gdb.exe with expat-1.dll support. Here are the major steps, I hope it can help others to build gdb.exe himself.

You need MSYS and MinGW installed in your system.

First, you need to build expat library.
1, Download the expat source.
2, Suppose your expat2.0.1 source code was located in c:\expat2.0.1, and you would like the generated dll installed in c:\install_expat
In MSYS, under /c/expat2.0.1, entering these command:
Code: [Select]
./configure -prefix=/c/install_expat --enable-shared3, make[press enter]
4, make install[press enter]
Then, you will have all the files in c:\install_expat. also, don't forget to run the strip command to strip the debug information. for example:
strip expat-1.dll will remove the strip information in this dll, and reduce the dll file size.

Second, build gdb
You need to copy all the files under c:\install_expat to c:\mingw, I suppose you have install MinGW in "c:\mingw", so, now, the compiler can find both the headers and libraries.

1, download the gdb source file, and unzip them, eg, they are extract to c:\gdb2010XXX
2, Create two empty folders, one is c:\obj_gdb, and the other is c:\install_gdb
3, in MSYS command, go to /c/obj_gdb
4, run these command:
Code: [Select]
../gdb2010XXX/configure --prefix=/c/install_gdb  --with-expat5, make[press enter] , this will build the gdb.exe and gdbserver.exe, take about half an hour in my P43.0 CPU.
6, make install[press enter]

After this, all the files were in c:\install_gdb
Also, don't forget to run the strip command to reduce the file size in c:\install_gdb\bin

I have upload the gdb7.0.1 version to gdb7.0.1_ollydbg.7z (http://qp-gcc.googlecode.com/files/gdb7.0.1_ollydbg.7z).

I  built it in TDM GCC 4.4.1dw2, also, I have comment the warning statement in symtab.c of the gdb source, so there is no such warning now. Since the new GDB 7.0.50 version and the GDB branch 7.0.90 is still experience the watch wxString lag problem I statement before.

Also, I build this gdb.exe statically link the expat library, so you don't need expat-1.dll.

Hi, all.
today, gdb 7.1 official released, see here: GDB: The GNU Project Debugger (http://www.gnu.org/software/gdb/)

I have build this version under Loaden's GCC 4.4.3. I can debug under Codeblocks, but I still have some problems. the major problem is that showing variables in the Watch window of C::B, and the command interpreter runs really slow when I debug the Codecompletion plugin DLL.

See a more details in Asm_gmail - Re: gdb-7.1 - last call before release (Wed, Mar 17th) (http://sourceware.org/ml/gdb/2010-03/msg00162.html).

Can some one help me? you can build a gdb yourself, or you can test the gdb I built from gdb7.1.7z (http://qp-gcc.googlecode.com/files/gdb7.1.7z)

Thanks.

Edit
You can compare these two version of gdb
gdb7.0.1_ollydbg.7z (http://qp-gcc.googlecode.com/files/gdb7.0.1_ollydbg.7z), I build from TDM gcc 4.4.1dw2,with static expat library, based on the official gdb 7.0.1 source code, and I only comment out the #psymbal warning message.
and
gdb7.1.7z (http://qp-gcc.googlecode.com/files/gdb7.1.7z), I built from Loaden gcc 4.4.3, with static expat library, based on the official gdb 7.1 source code.

You will notice that the first one gdb7.0.1_ollydbg.7z (http://qp-gcc.googlecode.com/files/gdb7.0.1_ollydbg.7z) runs really faster then the second one.

I have build this version under Loaden's GCC 4.4.3. I can debug under Codeblocks, but I still have some problems. the major problem is that showing variables in the Watch window of C::B, and the command interpreter runs really slow when I debug the Codecompletion plugin DLL.
In here, there is no delay, very fast! :lol:
I'm sorry, that my original testing method was wrong, now, I have exprenced the debug lag problem too.( using gdb 7.1)

Here is the instrucntions to reproduce the problem:

1, start debugging
2, set a breakpoint in the parserthread.cpp, line 450
3, add a watch variable: token, which is a wxString
4, when the debugger reach the breakpoint, you will notice the debugger toolbar will disabled for several seconds.
5, then, you will see the token's value in "watch window".
6, you press "step" button in the debugger toolbar.
7, you will notice that the toolbar disabled agian for a few seconds, and the lag happens again.

I have trid the mingw gdb 7.0.1, these is no such time delay probelm.

Hi, all.

I have successfully built the mingw gdb 7.1.50 snapshot from the source gdb-7.1.50.20100521. tar.bz2 (http://ftp://sourceware.org/pub/gdb/snapshots/current/gdb-7.1.50.20100521.tar.bz2) link to expat static library (under Loaden's mingw 4.4.4 and Msys)

You can download it from gdb-7.1.50.20100521.7z (http://qp-gcc.googlecode.com/files/gdb-7.1.50.20100521.7z)

It is just runs fast as gdb 7.0.1.
As you know, the 7.1 version has some problems(time delay when showing wxString), this gdb 7.1.50 don't have this problem.

Have a try!!

Updated 2010-06-15
I found that the gdb.exe build from tdm-gcc 4.5 lacks iconv library, this will cause the problem like: Bug 10908 - error reading variable for char variable (http://sourceware.org/bugzilla/show_bug.cgi?id=10908), So, I rebuild the gdb under Loaden's GCC 4.4.4, now, it works fine, so, I suggest you need to download the file gdb-7.1.50.20100613withpython-2.7z (http://qp-gcc.googlecode.com/files/gdb-7.1.50.20100613withpython-2.7z)

2010-06-14
Hi, all. Today, I have build the latest gdb CVS under TDM-MinGW 4.5 dw2 with python support.

Firstly, you need to install the python environment, I use header file and libs in this package python Python 2.6.5 Windows installer (http://www.python.org/ftp/python/2.6.5/python-2.6.5.msi)

the gdb package can be downloaded from Loaden's site: gdb-7.1.50.20100613withpython-2.7z (http://qp-gcc.googlecode.com/files/gdb-7.1.50.20100613withpython-2.7z)

Now, I have testing the pretty print function of python, it works fine!! :D

There are the brief steps to use the pretty print function. I mainly followed STLSupport - GDB Wiki (http://sourceware.org/gdb/wiki/STLSupport)

The only difference is that, you can create a single *.gdb file, then use this command  "source *.gdb"  instead of using a .gdbinit file.

Then you can add it here: in the debugger setting dialog, see attachment image

Also, I think many py pretty printers can be added, like the wxWidgets support.
http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/misc/gdb/print.py

Here is the test code:
Code: [Select]
#include <iostream>
#include <string>
#include <vector>

using namespace std;

typedef vector<string> vstr;

int main()
{
    vstr vvvv;
    vvvv.push_back("bla bla");
    vvvv.push_back("aaabbb");
    string v0 = vvvv[0];
    cout << "Hello world!" << endl;

    return 0;
}

Then ,you can enter "print vvvv" in the debugger edit control, and here is the log output:

Quote
> print vvvv
$2 = std::vector of length 2, capacity 2 = {"bla bla", "aaabbb"}

Nice.
You can see this wiki page:
STLSupport - GDB Wiki (http://sourceware.org/gdb/wiki/STLSupport)
So, I think you can see the python script in the GCC's trunk.
By the way, it seems the Latest svn://gcc.gnu.org/svn/gcc/trunk/libstdc++-v3/python does not works correctly. I just use an old revision.

As xunxun said, I do not have a 64bit windows system. so I can't build a native 64bit windows gdb. I guess that you can follow my instructions in the first post and build it yourself. Or I have searched on Google for you and found that you can download on from:

It works ... but I found odd thing: sometimes gdb crashed on start. Looks like it try to prepare non-initialized local variables in main for pretty-printing. At least switch off corresponding option in Setting results in stable (and really fast) further operation.

Did you mean like below:
Code: [Select]
int main()
{
int a;// set breakpoint here

vector<string> b;

}
Then, you try to use pretty printer to show the variable b?
surely, b is non-initialized local variable, and this will let gdb/python script go to some un-expected behavior, like go infinite loop to show its member.

This is a known bug, I have discussed this bug in this forum before. I also have a workaround patch on GDB to compare the line number between the current PC address and the variable line, then try to filter out the non-initialized local variable. But I do not think this patch will be much reliable.

It works here.

1. c::b 10.05 is too old, I suggest you should use the latest nightly build debugger branch version.
2. you need to open the "Debugger settings" dialog, then uncheck the "enable watch script" option, if you use python based gdb. (I noticed that if you check this option when using python pretty printer, there will be a crash on gdb).

HAPPY CHINESE NEW YEAR (Dragon year is coming)
The new pre-build binary package can be found in gdb2012-01-19.7z (http://qp-gcc.googlecode.com/files/gdb2012-01-19.7z), it is gdb's latest cvs version with my patch (http://qp-gcc.googlecode.com/files/gdb2012-01-19.patch) applied.
I remove the hard-coded relocated code, because gdb can relocate correctly, see: Doug Evans - Re: Possible fix for mingw32 directory relocation problems (http://sourceware.org/ml/gdb-patches/2012-01/msg00676.html) related discussion for more details. The other parts of the patch include: work around the crash problem of local variable print, adjust some minor file paths of call-stack print.

EDIT 2012-02-16
Update to new release, and fix a tiny regression since 2011-12-12.
See more details in the first post in this thread.

Since I am one of those unlucky souls suffering from the dreaded message
'Cannot evaluate function -- may be inlined' while trying to see a string
at the watch window, I'd  thought to give it another try with a recent
version of gdb with python support which I've built with the help of instructions
from the http://code.google.com/p/qp-gcc/wiki/build_gdb_msys_en

Code: [Select]
Starting debugger: C:\MinGW\bin\gdb.exe -nx -fullname  -quiet  -args E:/codeblocks_svn/src/devel/codeblocks.exe
done

[debug]> set prompt >>>>>>cb_gdb:

Yup, right off the head. Although I've failed to build it at first
because of the reading fail of the warning about the line endings.

Anyway, with still no joy and seeing the same dreaded message
about strings.I've turned on the full debug log and hovering over
a string variable I noticed this.

Code: [Select]
[debug]> whatis fileToParse
[debug]type = std::string
[debug]>>>>>>cb_gdb:
[debug]> output &fileToParse
[debug](std::string *) 0x3f0fd14>>>>>>cb_gdb:
[debug]> output fileToParse.c_str()[0]@fileToParse.size()
[debug]Cannot evaluate function -- may be inlined
[debug]>>>>>>cb_gdb:

Cannot evaluate function -- may be inlined

whereas using the commands <print> or <output> from the debugger
log window prints the string nicely.
Code: [Select]
> p fileToParse

[debug]> p fileToParse
[debug]$5337 = "E:\\c++11.denemeler\\clang_cc\\TestFiles\\classtest.cpp"
[debug]>>>>>>cb_gdb:

$5337 = "E:\\c++11.denemeler\\clang_cc\\TestFiles\\classtest.cpp"
> output fileToParse

[debug]> output fileToParse
[debug]"E:\\c++11.denemeler\\clang_cc\\TestFiles\\classtest.cpp">>>>>>cb_gdb:

"E:\\c++11.denemeler\\clang_cc\\TestFiles\\classtest.cpp"

So I am guessing that debugger plugin is sending the wrong commands to the debugger
Is there a way to fix this?

Edit: Oh darn it.I've just noticed there is a option for disabling watch scrips if you are using python
enabled gdb in debugger configuration window.All is well I can see my strings now.

Aaaarg! nevermind - I picked the wrong debugger.
@Teodor: Is it possible the clearly show the name of the debugger chosen before a debug session starts? This happens rather often to me... as I switch often...

However - I see another issue: "Import error: site" and that's it. :-/ Looks like the python stuff is broken for me...

Yes, we do. And on the very top the debugger configuration is shown as well. This can be well overseen. Any change to at least colour the debugger config in blue, bold or alike?

And no fun: This debugger CRASHES with wx, too. I thought it would not, but after adding Python (32 bit) DLL and PATH I see this crash:

Anybody that can confirm the issue? It also happens on the command line, btw. I am trying to debug the debug version of Code::Blocks as you see. standard "Hello World" works.


Edit: Its the same error as with TDM now, btw.. Not the very same, as the path differs. So its really the new ollydbg debugger. I need to switch back to the old one. :-(

I don't have this kind of issue in my system, as I'm using debug version of wx2.8 and debug version of wx 3.0.2 and git header. This is what I am going to do:
1, use some release version of wx 2.8
2, I will try to use GDB from TDM and see whether it has such error.

Will report back soon.

Hi, Morten, I guess this is an GCC issue comes from TDM's GCC. I just have those test environment:
1, I have a wx 2.8 release which is built by "MinGW-Build 4.8.1 dw2" (Note MinGW-Build 4.8.1 comes from MinGW-W64 project)
2, I build C::B against this wx 2.8, but I build it with "MinGW-Build 4.9. dw2".
3, I can debug C::B under my build GDB(2016-01-30) without any issue.

Post by: ollydbg on February 01, 2016, 07:43:36 am
Morten, I did another dummy test.

I just download the binary files from our 16.01 release, and unzip it.
I then create a very dummy project, and I set the output file to the codeblocks.exe and add all the necessary args like below:
Code: [Select]
--debug-log --no-dde --no-check-associations --multiple-instance --no-splash-screen --verbose -p debug
Then I can debug this dummy project.
Then I see I can correctly debug the codeblocks.exe(also no debug information inside the exe and dlls), and I see all dlls are loaded correctly, and no error reported. This means my GDB dose not report the error when loading the wx dll build from TDM gcc(I think our 16.01 release binary was build from TDM GCC, right?)

Here is the full log, you can have a look, I can pause the debugee, and print all the shared libraries:

There is no * mark, and we have "debug" information in the "wxmsw28u_gcc_cb.dll"? Did you locally strip this dll in your computer? This may destroy the dll if the "strip" command has some issue. (I remember the exchdl.dll has such issue, so we can't strip on it)
Title: Re: [OT] unofficial MinGW GDB gdb with python released
Post by: ollydbg on February 01, 2016, 07:46:57 am
Hi, Morten, I guess this is an GCC issue comes from TDM's GCC. I just have those test environment:
1, I have a wx 2.8 release which is built by "MinGW-Build 4.8.1 dw2" (Note MinGW-Build 4.8.1 comes from MinGW-W64 project)
2, I build C::B against this wx 2.8, but I build it with "MinGW-Build 4.9. dw2".
3, I can debug C::B under my build GDB(2016-01-30) without any issue.

This is what I get when debugging the above settings:

OK, my guess is not correct. Here is my further test:
Code: [Select]

E:\code\cb\16.01\codeblocks-16.01-nosetup\share>cd ..

E:\code\cb\16.01\codeblocks-16.01-nosetup>which strip
E:\code\common_bin\strip.EXE

E:\code\cb\16.01\codeblocks-16.01-nosetup>strip wxmsw28u_gcc_cb.dll

E:\code\cb\16.01\codeblocks-16.01-nosetup>
I just stip the debug info on the wx dll, and debug codeblocks.exe again. No issue here, and Here is the result:

Look, there is a "*" mark on the wxmsw28u_gcc_cb.dll, and still I don't see any error here.

EDIT:
Please clean up your PATH, and make sure you have 32 bit 2.7.x python installed. :)

Title: Re: [OT] unofficial MinGW GDB gdb with python released
Post by: MortenMacFly on February 01, 2016, 07:59:25 pm
My setup is TDM/MinGW 5.1.0. I compiled wx28 and C::B with that.
My guess still is, that the debugger is wrong. I'll explain, why:
* I've checked my PATH several times, its correct
* I even override all PATH settings in C::B using the EnvVars plugin

In all cases it works just fine with any previous release of gdb.
It fails with GDM/TDM (of 5.1.0 distro) and your 2016' gdb.

All GDB use the very same Python (2.7, 32 bit) environment.

Because of that what other than the GDB should be the reason? Do you understand what this GDB error message actually means?

I don't know the error message means, maybe, I need to debug the GDB(debug GDB under GDB), but I can't reproduce on my WinXP.


Today, I just did the test on a Win7 64bit computer. GDB works just fine when loading the C::B. It is very simple to do the test.

1, download a 32 bit python installer(2.7.11), and install it.
2, download my gdb achieve, and unzip it
3, download the C::B 16.01 non-setup zip file, and unzip it.
4, copy the installed python files to the GDB's bin folder
5, start cmd
6, just run "gdb.exe E:/cb1601/CBlauncher.exe"
7, enter "r" to start the C::B.
8, I see C::B 16.01 correctly opened, and GDB does not show any error.

I'm not sure what is your system, I guess your system has some issues.

4, copy the installed python files to the GDB's bin folder
Do you really mean all the files (and sub-folders)? I only copied the DLL.

So its basically a Python with GDB then, right?

I personally copy all the files and sub-folders of the installed python to GDB's bin folder.
