Re: Debug ProjectCenter

I am now trying to build all of gnustep with debug information.

I am using clang and am compiling from the repos in GitHub at the HEAD version

Have built libobjc2 and libs-back, libs-base and libs-gui all with debug=yes.

I then built project center also with debug=yes

Now when I am trying to run ProjectCenter installed with GNUSTEP_INSTALLATION_DOMAIN=LOCAL i am getting an error in an Assert :

Seems the problem is in libobjc2, but I don’t have a clue how to get past it.

I recompiled with that option.
But I still get the same behaviour.

you also compiled gnustep base/gui and back and even libobjc with debug symbols?
Having the full stack of dependencies with debugging symbols, and sources still left on disk,
usually works for me.

I am running the program from the .app folder that the build creates within the project root folder.

I do gdb ProjectCenter.app/ProjectCenter

Hey Daniel

Use “make debug=yes”. That should work for you.

Hi,

I am trying to do some changes in the sources of project center and am using gdb to debug.
How do I disable gcc optimisations ?
I tried putting :
CFLAGS = -g -O0
in the GNUmakefile.preamble, but I am still getting values that show <optimized out> when I print them, and unexpected jumps in the code.

Thanks,
Regards
