On AIX, we just installed some AIX-base-system software that

pkgsrc has /usr/pkg/lib/libexpat.so as a 64-bit object for
fontconfig et al.
I don't have a modern AIX system at hand, so where are 32bit and 64bit
It would appear they are stored in the same directories (/lib, /usr/lib,
/usr/pkg/lib). Not sure I understand the question.
Sane ELF systems silently skip objects of the wrong
type, making this easier.
I guess I'm dealing with an not-so-sane XCOFF system :)
I know that AIX's ld lets us embed library paths into the loader, but in
the past it's caused objects to look in the buildlink-time directory for
the package rather than the normal library locations.
I will try to build with LDFLAGS=-blibpath:/usr/pkg/lib:/usr/lib:/lib
and see what happens...
I have tried setting LDFLAGS with...
2) -bnolibpath -L /usr/pkg/lib
3) -bsvr4 -L/usr/pkg/lib
The first (1) is supposed to explicitly put the paths in the header.
(2) is supposed to not write the header, putting only in the contents of
LIBPATH (which I set appropriately)
(3) is supposed to put the `-L' arguments in the path
(4) is supposed to use any `-L' or `-R' arguments for the path.
None of these work. I'm not sure if pkgsrc is overriding these options.
But it simply isn't working.
In every case the header looks like this...
# dump -X64 -H /usr/pkg/lib/libfontconfig.so
Loader Header Information
VERSION# #SYMtableENT #RELOCent LENidSTR

INDEX PATH BASE MEMBER
4 libiconv.a shr4_64.o
5 libc.a shr_64.o
My only workaround now is to set LIBPATH at runtime, which is awful!
