I am writing a plugin for audacious, and I am experiencing random segfaults. I looked around and I found that I can process the program's core dumps with gdb.
So I did that, and I got this output:
As you can see, it says no debugging symbols where found anywhere. I want to compile audacious with debugging symbols, but I am not sure how. I tried editing configure, which only includes a file named buildsys.mk, so I edited that and removed the -s flag from the linker, and made sure that the -g flag is passed to the compiler. The gdb output above is after I did that, so apparently what I did had no effect.
So how can I retain debugging symbols when compiling audacious? The problem is that I am only writing a small plugin, and haven't got a grasp of the while audacious code.
UPDATE: I added debugging symbols for gtk+ and glib (and also tried the CFLAGS=-g option), and I got a couple of coredumps analyzed. The bottom line is this:

Can anyone make anything out of this? :-\
