I think there is a bug when debugging. (I'm using windows XP and Mingw from TDragon.
My program was linked to the debug library of opencv. which are located in:
F:\test1\lib\***
the source file is located in
F:\opencv\src\cxcore\***
It seems that I can't set break points in the source file. GDB complaints that :
> break "F:/opencv/src/cxcore/cxarray.cpp:104"
No source file named F:/opencv/src/cxcore/cxarray.cpp.
Breakpoint 3 ("F:/opencv/src/cxcore/cxarray.cpp:104) pending.
>>>>>>cb_gdb:
But my source file is exactly named "F:/opencv/src/cxcore/cxarray.cpp", my program will call some function in the cxarray.cpp.
Also, another problem is I can't "step into" the source code. ( This functionality is available in the last svn release).
The problem seems happens in this SVN version. The last version works well as I can remember.
I search the forum and found some related discussion.
I download the zip from the thread:
http://forums.codeblocks.org/index.php/topic,4896.msg38390.html#msg38390
And still it can't set break point in the DLL source file.
Some one can explain it?
Thanks.
ollydbg,
Just a thought, but TDM's release of GCC 4.3.2 TDM-2 dated 1008-12-09 includes a fix that solved a similar debug problem that I was having. This was for break points in a header file so it may not apply, but you might consider it if you are using an earlier release.
HI, Thanks for your hint. Actually, I already use the TDM's 4.3.2 TDM-2 2008-12-09 as you mentioned.
Maybe, it is related to the "setting break point in a header file" issue, maybe not, I'm not sure. :(
The problem seems comes from "How does the compiler and GDB handle with the path of source file".
I test the zip file from :
http://forums.codeblocks.org/index.php/topic,4896.msg38390.html#msg38390
There are two build targets. One is a exe file. The other is a DLL file.
The exe file will load the DLL file when it runs. Both of these targets were build with Debug enabled. So, I think that in the "TestDLL.dll", there are some part to reference it's source file path.
I put the project in "C:\DebugTest"
main.cpp was located in "C:\DebugTest\TestApp"
dllmain.cpp was located in "C:\DebugTest\TestDLL"
But I can't set break point in the "dllmain.cpp".
GDB reported:
>>>>>>cb_gdb:
> break "C:/DebugTest/TestDLL/dllmain.cpp:16"
No source file named C:/DebugTest/TestDLL/dllmain.cpp in loaded symbols.
Breakpoint 2 ("C:/DebugTest/TestDLL/dllmain.cpp:16) pending.
It is very confused that sometimes the compiler can use the "relative source file path", and sometimes, they use full path. So does the GDB. (I'm not sure how does the linker handle the path related issue).
So, I'm totally lost in this problem :(, can someone give a clarification? Thanks.
Thanks jens.
I have this option enable by default.
see the attachment image.
I also enable the full compiler output, when compiling, the output are here:

When debugging the exe file, I still can't set break point in anywhere in the "dllmain.cpp".
If you have enough time, you could help to test the zip file in that thread. Thanks.

correct! setting break points in the code below works!
// a sample exported function
void __declspec(dllexport) MyFunction(const LPCSTR sometext)
{
/** SET BREAK POINT HERE VVVVVVVVVVV **/
MessageBoxA(0, sometext, "DLL Message", MB_OK | MB_ICONINFORMATION);
/** SET BREAK POINT HERE ^^^^^^^^^^^^ **/
}
The breakpoints can't be set in the function of DllMain.

The breakpoints can't be set in the function of DllMain.
I can set breakpoints in any of the three functions dllmain.cpp and in MyFunction without problems.
And gdb stops there of course.

It is very interesting, when I renamed the project folder name from "C:\DebugTest" to "C:\DebugTest1".
Then I open the cbp file and debug without rebuild the project. Then the gdb complaint that: (I'm using the TDM-mingw version)

You can see when gdb started, it use the command line:
Command-line: D:\Program Files\CodeBlocks\MinGW\bin\gdb.exe -nx -fullname -quiet -args bin/TestApp.exe
which has a parameter "-fullname", so I can't set break points in anywhere of the source file. Because the debug information in both exe and DLL file were reference to " C:\DebugTest\***".
As a workaround, I should rebuild the Target.

This patch is not necessary. Run the following script at Script Console -
ShowInfo(GetCompilerFactory().GetCompilerVersionString(_T("gcc")))
It should show you GCC version no. See following screenshot (showing result in my pc).
(http://img175.imageshack.us/img175/2937/gccverrz9.th.png) (http://img175.imageshack.us/my.php?image=gccverrz9.png)
I can't get the version use script.
and my config:
set PATH=%CD%\bin;%PATH%
set CPATH=%CD%\include;%CD%\lib\mingw\mingw32\4.3.2\include;%CD%\lib\mingw\mingw32\4.3.2\include\c++

If possible, you can try svn r5390 and see if the issue is fixed for you.
thans! I confirm this question exist also.
I can't give MinGW TDM-2's version with r5390.
please post the output of the gcc (C- not C++-executable) you have configured in toolchain executables tab, if called with "--version" on commandline.
Please call it with absolute path as configured in the settings: <Compiler's installation directory>\bin\<C compiler> --version
Make sure you have not accidently added "bin" to the "Compiler's installation directory" in the settings !!
Thanks, it works, setting breaking points in dummy code also works.
so, in the header file:
#ifdef __cplusplus
extern "C"
{
#endif
void MyFunction(const LPCSTR sometext);
BOOL WINAPI DllMain(HINSTANCE hinstDLL, DWORD fdwReason, LPVOID lpvReserved);
#ifdef __cplusplus
}
#endif
#endif
BOOL WINAPI DllMain(HINSTANCE hinstDLL, DWORD fdwReason, LPVOID lpvReserved)
{
static int a = 0;
switch (fdwReason)
{
case DLL_PROCESS_ATTACH:
// attach to process
// return FALSE to fail DLL load
a++;
break;
case DLL_PROCESS_DETACH:
// detach from process
a++;
break;
case DLL_THREAD_ATTACH:
// attach to thread
a++;
break;
case DLL_THREAD_DETACH:
// detach from thread
a++;
break;
}
return TRUE; // succesful
}
I can set break points in the line of "a++", and it works. Thanks.
Hi,
I've got a problem compiling C::B as an rpm-package for current development version of Mandriva Linux 2009.1 distribution. I guess the problem is that when building rpm packages this distribution forces the use of GCC option -Werror=format-security and it produces several error messages like this:
wiz.cpp: In member function 'void Wiz::CopyFiles(cbProject*, const wxString&, const wxString&)':
wiz.cpp:757: error: format not a string literal and no format arguments
make[4]: *** [wiz.lo] Error 1
make[4]: Leaving directory `/home/olelukoie/rpmbuild/BUILD/codeblocks/src/plugins/scriptedwizard'
Is it possible to fix and make C::B compilable with this option? (As I said there are several other messages of the same error type).

continue,
on second break, the current eip is 417750, but the disassembly window show the asm code is same as the first,
can't find the current asm code.
my english is pool, sorry
I tested it, but there's no problem.
In first break, the disassembly code is like below:
