debugging - step into with VS8

[yaro]

I compiled wxWidgets 2.8 in debug mode in visual studio 8, created a wxWidgets project in latest codeblocks with the wizzard. The project uses VS8 for compilation. Wizard was complaining but after setting up all paths and dependencies it compiles and debugs my application.

But sometimes breakpoints don't work, especially if they are set on a line that has only a comment. If set on a line that has a statement then they work.
However I can't do step-in once breakpoint occurs. When I press shift+F7 and want to see what happens in a wxWidgets call, nothing happens. This works perfect in VS8 and is crucial to debug bugs in function calls with incorrect parameters or find bugs in used libraries.
I really need step-in, I can't use codeblocks if it doesn't work with VS8
I also tried adding the wxWidgets src path with all the cpp files to the Debugger options in project preferences (C:\work\wxWidgets-2.8.0\src) but it didn't help.

Does it work for anybody?

Hi ,
codeblocks doesn't work with VS8 in debug mode . at last in this time .
codeblocks use GDB form MinGW .
I think you can use MinGW that will help you move your Project to anther OS with GCC

You can't step-in if there are no debug symbols for that code. Have a look in the debugger's logs (both of them) for error messages regarding symbols reading.

I link against the same wxWidgets debug .lib files which have debug symbols. I also use multi threaded DLL debug runtime library /MTd.

If I link against the same wxWidgets lib files in VS8, step in works.

I should also mention that I can step past "return xx" in "bool MyApp::OnInit()" and get into wxWidgets app.h, but didn't manage to get to any *.cpp file ever. So I don't think the reason is what you described.

In debugger window there is:

As u can see from "Symbol search path is: " it does have access to the directory where pdb files for wxWidgets are.
I dont know what logs do you mean exactly. If I run the CB with /d switch I don't see any logs on my disk or any new windows in CB.

I found out how to enable Debugger(debug) window which shows log of the debugger.

This is what I found:

Is it not implemented?

Hmm, if the log says so . Sorry but I haven't worked with cdb lately so I couldn't remember its status...
