Debug issue in CB 13.12

Hi,
I'm using Code::Blocks 13.12 to debug ffmpeg 2.1 in Fedora 18. I create a console application with 'This is a custom Makefile' marked in project->Properities->Project settings. Please see the full debug log.

===================
All these gdb commonds work fine in terminal. And CB 10.05 does not have this issue.
I have spent much of time to google or search in this forum, but I cann't find any useful infomation.
oBFusCATed:
Why are you executing the run command manually?
What is the problem really? The app doesn't start?
p.s. please use code tags (# button in the interface) when pasting long logs.

Hi oBFusCATed,
Why are you executing the run command manually?
Same issue as executing the run command automatically.
What is the problem really? The app doesn't start?
The real problem is :
[Inferior 1 (process 13056) exited with code 0177]
Cann't debug ffmpeg_g. I think there are something wrong when gdb load ld-linux.so.2.
oBFusCATed:
If there is such problem then your system won't work at all.
Does your app depend on non-system shared libraries?
If it does then I suppose this is the problem, because your LD_LIBRARY_PATH is wrong.
Do you use rpath linking?

Hi oBFusCATed,
Thanks for your help. The issue is related with LD_LIBRARY_PATH. I'll post the details later.
