[OT] unofficial MinGW GDB gdb with python released

[ollydbg]

But could you please test by setting a breakpoint in the codeblocks' source code? this case, it didn't work here.

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.

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.

main should be in src/src/main.cpp not in the console runner

[MortenMacFly]

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

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. ;-)

[ollydbg]

main should be in src/src/main.cpp not in the console runner

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).

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

[ollydbg]

@morten

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

It seems there is still some bug in TDM-MinGW 4.4 or GDB.exe7.0  

[theOcelot]

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.

Can you try a nightly build?

[theOcelot]

Can you try a nightly build?

Who, me? Of CB? Sure, I guess. Do you mean get it from SVN? I can't find a binary download link for the nightlies anymore. I also don't know for sure how the build will work with my wxWidgets.

[oBFusCATed]

theOcelot: yes you  :lol:,  binary nightly build (not hyper new, but uber new relative to the 8.02 release) can be found in the nightly subforum on this site  :lol:

[ollydbg]

@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.

[theOcelot]

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. 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.

[ollydbg]

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.
