Subject: 64 bit compiling problems with IRAF and GRASPHi Mike,
I'm trying to compile GONG's GRASP package on a fedora core 3, 64 bit
architecture, linux box with iraf 2.12.2 installed (and patched) and I'm
running into a bit of a library problem.When ever a package tries to link I get this error:
/usr/bin/ld: warning: i386 architecture of input file
`/opt/iraf/iraf/bin.redhat/libvops.a(achtsu.o)' is incompatible with
i38686-64 outputHave you guys run into this? Is there a way I can get around this?Thanks a bunch!

Cc: fitz@tucana.tuc.noao.eduHi Trina,
64-bit compilation is not supported by IRAF and won't likely be
anytime soon given NOAO's decision to "scale back" its IRAF work. The
32-bit compiled binaries will run on some 64-bit hardware but won't take
full advantage of the machine or address space, but it means you can
develop on a 32-bit machine and move the package when done.-Mike>From gressett@noao.edu Mon Sep 19 12:40:03 2005

Subject: Re: 64 bit compiling problems with IRAF and GRASPThanks Mike!Though I'm still sort of confused. None of the GRASP code was developed on
the 64-bit platform. So when I run mkpkg to generate the binaries, is
there a way to trick the compiler into compiling 32-bit binaries? The binaries I generated on my 32-bit platform seem to work fine on the
64-bit platform. TrinaOn Mon, 19 Sep 2005, Mike Fitzpatrick wrote:> Hi Trina,

Trina,
GCC does have a "-m32" flag to produce 32-bit binaries which
you can enable by defining setenv XC_CFLAGS "-m32"
setenv XC_FFLAGS "-m32"However there is no guarantee this will work, you're better off compiling
on a 32-bit machine.
