[SAC-HELP] installing 05Jun07 distribution on 64 bit linux

[Renate Hartog]

Thought I'd share my experience installing this version of the source code 
on my 64-bit Red Hat Linux system;

from Changes file:
2005/05/26 Brian Savage <savage13 at dtm.ciw.edu>
         * Fully integrated libedit into build process -> turned out to be 
a little tricky on 64-bit if you want to compile it with -m32
         * Updated Readme, License, History, Readme.buildsac files
         * Removed extra CC=cc lines in makefile
         * Updated Makefile for better install process

These are the problems I ran into with fixes:

-can't find X11 library: fixed by adding a soft link called libX11.so in 
/usr/X11R6/lib to the libX11.so.6.2 file that was in there (a 32-bit 
library).

-to compile for 32bit rather than 64 bit: Added the following lines to the 
sac/src/makefile:
ifeq ($(MACHTYPE),x86_64)
   DEFINES += -m32
endif

  This compiled all the SAC-source code with the flag -m32

-ld can't find crt1.o -> fixed by installing glibc-devel.i386 which put 
the needed file in /usr/lib

-sac compiled, but died with segmentation fault -> turns out there still 
were some 64bit libraries: libedit did not get compiled with the -m32 
flag, the sac-distribution actually installs this library from scratch 
from a tar-file. I edited sac/libedit/libedit-2.6.9/Makefile.in and added 
-m32 to all the $(CC) calls that did NOT use CFLAGS, and I set an 
environment variable CFLAGS to -m32. Then I made a NEW tar-file 
libedit-2.6.9.tar.gz (after copying the original just in case).

-cd'd back to sac/src, did make clean to remove any old 64-bit stuff, then 
did make and it now seems to be working.

Thanks to all who respond to this email list because I wouldn't have been 
able to figure it out so quickly without your previous experience 
compiling on 64-bit!
