The 06 January 2009 build (5382) is out.
ollydbg:
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!
--- Code: ---// 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 ^^^^^^^^^^^^ **/
}
--- End code ---
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.

Iwill test it with gdb 6.8 on w2k too, this evening.

For me it still does not work. But I am using the GCC 3.4.5 compiler suite ang GDB 6.6 (otherwise I cannot debug into wx code). It seems an issue with the compiler/debugger version obviously... Oh dear... Should I really finally upgrade my dev frameworks?!
ollydbg:
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:
--- Code: ---Command-line: D:\Program Files\CodeBlocks\MinGW\bin\gdb.exe -nx -fullname -quiet -args bin/TestApp.exe
--- End code ---
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.
