Problem debugging a wxWidget application with Eclipse [message #775224]

After installing Eclipse Indigo and wxWidget 2.9.3 I built the "minimal" application
(a sample ditributed with wxWidget)using mingw32.

Debugging works but when I start debugger it opens a window with a message:

Can't find a source file at "../mingw/main.c"
Locate the file or edit the source lookup path to include its location.

When I push F8 (Resume) the application really starts and works.
Before resuming it seems the code is looping somewhere..

Does anybody know how to explain this weird behaviour?
Thanks

Something similar is happening to me, as well - some more info on it, disassembly for me shows: "call 0x403b2c <GetCommandLineA@0>" as where it's hanging up at. However if I run the executable by itself, it seems to run just fine. I'm running my own program, just running Eclipse Indigo, no widgets.

I solved it.
Click on "Debug configurations..."
Set your C/C++ Application and Project.
Click on the tab "arguments" and look at the Working directory: it should be wrong, like:

${workspace_loc:project_name}

Change to something like

${workspace_loc:project_name\Debug}

or whatever is the right path.
Most important, click on the Debugger tab and check Load shared library symbols automatically. Then, on Source tab, check Search for duplicate source files on the path.
That's it.
EDIT:
Also enable autobuild.

I did everything as stated, yet I'm still getting the error on mine. The output from gdb in the console is

[New Thread 2596.0x238]
Cannot access memory at address 0x1
Cannot access memory at address 0x1
Cannot access memory at address 0x1

I have a similar problem. It mentions: "Can't find a source file at "../mingw/gccmain.c" Locate the file or edit the source lookup path to include its location."

Also, when I start debugging, it mentions: No line 20 in file "HelloWorld.cpp". Line 20 is the line where I placed my breakpoint and it's definitely there.

Right click on the project, go to Debug As - Debug Configurations - Debugger tab - And unclick "Stop on start up at" (which in my case was saying Main). I am not an expert at all, but I think the debugger is trying to stop on the Main at startup and something related to the widget creates the problem (?).

Note: in my case, I was getting the Can't find a source file at "../mingw/main.c"
Locate the file or edit the source lookup path to include its location... with Qt in Eclipse... Hopefully helps...
