[SAC-HELP] sac on 64-bit SMP box

[Derek Schutt]

Hi Brian,

Thanks for your quick response.  I actually read that posting (by you I
think?) in the archives, and it's clear that my post was lacking in
information.  In the directory containing the SAC makefile, I linked cc
to gcc32 ("ln -s gcc32 cc"), which presumably would compile it at a
32-bit binary.  However, I run into the problem below with the X11
library.  My guess is that I'd need to compile this library with gcc32
too?

I don't have the precompiled binary, but have just requested it and will
post back when I get it and see if it works.

Thanks,

Derek
