I just got a new computer today, a dual processor, dual core Sun machine running 64-bin Fedora Linux. When I try compiling one of my SPP packages on it, the files complie OK, but I get lots and lots of messages like this when linking:/usr/bin/ld: warning: i386 architecture of input file '/data/oir/IRAF2.13//iraf.pkg/noao/bin.redhat/libsmw.a(shdr.o)' is incompatible with i38686-64 outputIs there something I can set? Or do I need a whole new set of IRAF binaries? The old executables worked fine, but I need to fix some bugs/add some features.-Doug Mink

Compilation on 64-bit systems is not yet supported, you'll have to use pre-built 32-bit binaries for both the core system and external packages. With proper compatability libraries installed on your machine and much munging of compile time flags to add a '-m32' option, it is sometimes possibles to build 32-bit binaries on a 64-bit machine but this is not something for mere muggles to attempt.-Mike

Hi, I am a new iraf user, using a new DELL 64-bit computer , and running iraf-2.12.2 which is installed on the department server. everything works so far, expect when I compile routines using 'fc' I have compilation errors, similar to the ones that Doug has reported. (at the end the file gets compiled, but when I run it , i get the message 'segmentation fault'.)This is the error message:
'/usr/bin/ld: warning: i386 architecture of input file `/iraf/iraf/unix/bin.redhat/libos.a(zraloc.o)' is incompatible with i38686-64 output 'I don't really understand Mike's answer about adding a -m32 option. Can anyone please help explain more in details, what can be done? or does anyone have some new clues about what to be done???Thank you!

For compilation using 'fc', you would do something like:[code:1:84ea7e0cb3]cl> fc -/m32 mytask.f[/code:1:84ea7e0cb3]where the '/' is used to passthru the -m32 flag to the underlying compilers. The earlier comments about this being non-trivial referred mostly to the need to install 32-bit GCC libraries alongside the default 64-bit compiler. Depending on what you're building there may be other dependencies as well, but try the above first and hope for the best.-Mike

Thanks Mike for your reply!!this works, problem solved!
in fact it seems to work without the '/' as well!Nelly
