Olly: try the patch http://smrt.is-a-geek.org/codeblocks/dbg_refactor/fix_breakpoints.patch
It should have fix for it.
There was another build failure in the scintilla code... some usage of UINT which failed on linux.

Mmmmh... here at work applying the patch works...?! I'll have a look at it finally... ;-)

Morten do you have some time to apply the last patch?

Here is another patch for the debugger: http://smrt.is-a-geek.org/codeblocks/dbg_refactor/dbg_refactor0004.patch

What it does:
1. Improvements to the backtrace window - the inactive stack frames are not shown as "??" any more
2. Fixed bug https://developer.berlios.de/bugs/?func=detailbug&bug_id=16146&group_id=5358
3. Some cleaning

Best regards

Yet another patch http://smrt.is-a-geek.org/codeblocks/dbg_refactor/dbg_refactor0005.patch
This one includes the changes from the previous one plus:

1. Fixed bug 13972 ( http://developer.berlios.de/bugs/?func=detailbug&bug_id=13972&group_id=5358 )
2. Modified one of the regexpr for matching lines of the backtrace (case #0)
3. Added two menu options to choose the default action on double click in the backtrace window ("jump to" or "switch to")

Hi, oBF, thanks!!!!!

I just apply this patch, and find a small bug.

The test code is the attachment of this message
http://forums.codeblocks.org/index.php/topic,11301.msg77123.html#msg77123

In debugger branch, I can set breakpoint in the function body.

Code

void __declspec(dllexport) MyFunction(const LPCSTR sometext)
{
    /** SET BREAK POINT HERE VVVVVVVVVVV **/
    MessageBoxA(0, sometext, "DLL Message", MB_OK | MB_ICONINFORMATION); *************breakpoint set here.
    /** SET BREAK POINT HERE ^^^^^^^^^^^^ **/
}

when the debugger hit the bp, cursor jumped to the wrong place,

Code

        if ( NULL != ProcAdd )
            {
            fRunTimeLinkSuccess = TRUE;
            ( ProcAdd ) ( TEXT( "Message via DLL function\n" ) ); *********when bp hit, the cursor always jump here.
            }

I think this is wrong behavior.

It works fine in the trunk version.

My environment: TDM-MinGW GCC 4.4.1 and GDB 7.02
and with patch from jens:
http://forums.codeblocks.org/index.php/topic,11301.msg77156.html#msg77156

thanks.

Edit

I just found that if the Call stack window was not opened during debugging, the cursor can jump to the right place.

, so, this is an issue of interpreting the backtrack output.

oBFusCATed · « **Reply #113 on:** October 19, 2009, 09:35:28 am »

Uau, you are quite fast

Can you provide a platform independent test case? (probably not because I'm sure it breaks because of the "__declspec(dllexport)" )
Can you paste here the output in the debugger log window after the "bt 30" command..
Unfortunately the output of that command is made for users not parsers and so it is quite unreliable

Thanks for the feadback

Ok, but I can only supply a windows test case, because I only have windows. I haven't tried linux till now.

That is the relevant output, I'll fix it tonight, when I get home.

Update:

Here is the fixed patch http://smrt.is-a-geek.org/codeblocks/dbg_refactor/dbg_refactor0006.patch
