G'day team Dan identified that there were problems building OpenChange on an AMD64 (x86_64) box. I certainly saw that with Fedora 7 on my x86_64 box.
I've got it partly sorted though. There are really two problems - we need to
use -fPIC and we need to make sure that we link to the 64 bit libs (i.e.
from /usr/lib64) when trying to build.
man gcc says:
-fPIC
If supported for the target machine, emit position-independent
code, suitable for dynamic linking and avoiding any limit on the size of the
global offset table. This option makes a difference on the m68k, PowerPC and
SPARC.
Position-independent code requires special support, and therefore
works only on certain machines.
It looks like we should use -fPIC for shared libraries on x86_64.
Also, there are a couple of places where we have dependencies on the library,
and there is some kind of libtool interaction. I didn't see why -lpopt made a
sensible dependency, so I just moved it to the build line.
Patch (inlined for review, attached for application) enclosed.
You still have to pass LDFLAGS for this:
./configure LDFLAGS=-L/usr/lib64
