Normally PIC is used in shared libraries, and not in archive (.a)
files. The only exception that I have heard of is AIX, which seems
to use .a files as shared libraries.
Perhaps you need to use --enable-shared to build shared libraries and
use the shared libraries?
I didn't want to use shared libs because then I'd have a dependency
problem and have to deal with -rpath and such. With all of my
(non-system) dependencies built statically, I can basically plop my
app (and its plugins) anywhere and it'll work without setting env
vars, which is much nicer (I think).
You can still achieve that kind of portability while using shared
libraries if you distribute the shared libraries with your app. All you
have to do is tell the linker that the shared libraries are relative to
the executable by using a combination of the "-z origin" linker option
and using $ORIGIN in your rpath.
