Thank you very much for taking the time to reply.
For the record, allow me to explain how I have things working
at the moment :-). This is all starting from a SuSE 9.1 base,
upgraded to the 2.6.8.1 kernel.
1) First, I set CC=gcc (the environment variable, that is, before
running configure and built the 64-bit binary, and installed
that.
2) Then, in a separate directory (I've been using the lndir
trick so that the build directories are separate from the
source code) I set CC="gcc -m32" and built the 32-bit stuff,
and installed that.
3) Then, I went back to the 64-bit directory and installed that again,
because the 32-bit stuff had changed a few things in places like
X11R6/bin to default to the 32-bit code.
At this point, the 32-bit stuff and most of the 64-bit stuff was working,
but "gimp" stopped working. It turns out that the upgrade isntalled
an incompatible version of libfontconfig in /usr/X11R6/lib64, while
gimp had previously been picking up libfontconfig from /usr/lib64.
(I have the advantage of having several machines, so I can upgrade
one and use the other to figure out what has changed). To
fix this, I went into /etc/ld.so.conf and moved /usr/lib and
/usr/lib64 to the top of the list, thereby placing them before
the X11R6 stuff.
Also, I have an NVidia "Quadro4 750XGL DH" card. The card's install
process resulted in the installation of a library:
/usr/lib64/libGL.so.1.0.6111
but at the moment /usr/lib64/libGL.so is pointing to the
compiled copy in X11R6, which I think is the "generic"
distribution. I'm not sure which copy
is "right". I will experiment with this some more.
Thank you again.
Sincerely,
Mike Albert
