[SOLVED] GDB and codeblocks (with QT -> QtWorkbench-0.6.0_alpha)

[gophix]

Hello,

I've got a problem using CodeBlocks with GDB. I'm using CodeBlocks 8.02 with MinGW (2 Versions: the one packed  to CodeBlocks and the one packed with QT_2009.3). Both versions of GDB ( 6.7.50.20071127 and 6.8 ) are working with CMD but not integrated into CB.

Here is the output with CMD to see if my compiler-Flags are working - seems to be fine.

CMD with gdb

Code

But when I run it in CB it stops (...because it can't find the sourcefiles).

Debug output:

I've testet many settings but nothing made it working
i.e.:

• CompilerFalgs: -ggdb3 | -gstabs | -gstabs+ (but normal using NO Flags, just the ones set by QtWorkbench)
        -> always with rebuild
• using / instead of \ in the pathes
• using "Additional Debuger search dirs"
• changing Type (Console Application | GUI Application)

EDIT 1:
This is the Debuger output after activating "Settings"->"Compiler and Debuger"->"Debugger Settings"-> "Display Debugers log"

How can I make CB helping GDB to find the sourcefiles? Normaly GBD finds the sources, but not when started from CB.

Thanks for all suggestions

EDIT 2:
So, I found out that this line (gdb) directory D:/QTTEST~1/ in the CMD with gdb makes a fault

Code

D:\qtTestDebug\bin\Debug>gdb qtTestDebug.exe
GNU gdb 6.7.50.20071127
...
This GDB was configured as "i686-pc-mingw32"...
(gdb) directory D:/QTTEST~1/
Source directories searched: D:/QTTEST~1;$cdir;$cwd
(gdb) break "D:/qtTestDebug/main.cpp:8"
No source file named D:/qtTestDebug/main.cpp.
Make breakpoint pending on future shared library load? (y or [n])

How to solve:

"Project"->"Properties..."->"Debugger"->"Additional Commands": Set the "Before Connection" to "directory ."

Have a nice day ;-) !
