Here is a little more information.
Where my problem comes in is that to link against Performer, I have to
use the -O option to gcc. If you don't do this then there are several
performer functions that cause "undefined reference to" linking errors.
If I remember correct from the linux beta FAQ, this is caused because
inline functions need to be turned on. (I can't find the note any more
about needed -O with linux performer, is it still required?)
I can use the -g option with -O in order to get debug symbols, and this
does allow me to step through my code (I am using DDD), except for
functions that get inlined or optimized in other ways (most of my
code). I tried just disabling inlining but still having -O, but that
still caused linker errors.
So what I would really like is to be able to compile a performer
application under linux without having to turn any compiler
optimizations on at all. Is this possible?

PS. I will try -g3 and see if that makes things any better.
