Dear IRAF support group,My name is matteo Monelli and I'm a PhD student working in Rome.
I have a question for you. I work on a HP workstation (HPUX11.0) and I'm
trying to compile Peter Stetson's software (allframe) using the 64-bit
options of my fortran90 compiler. Since there are IRAF libraries linked
(libimfort.a,libsys.a,libvops.a,libos.a), I'd like to know wheter it is
possible have them compiled for this 64-bit option and how.Thank you very much for your suggestionsmatteo monelli

Hi Matteo,
The short answer is unfortunately no. The IRAF host system interface
(i.e. libos.a) is the foundation for the rest of the IRAF libraries and at
this time is not 64-bit clean. This means things like memory pointers,
file descriptors, etc would be compiled with a 64-bit address but wouldn't
be properly understood by IRAF without some work on various parts of the
system. On 64-bit platforms like the Dec Alpha we get around this by
producing 32-bit binaries, but this will become more of an issue as 64-bit
CPUs become common and the support for 32-binaries declines. At the moment
you'll need to either stick with 32-bit only or else port the ALLFRAME code
to use a different image interface library (e.g. CFITSIO to deal with FITS
images).
Sorry we couldn't help.Regards,
Mike Fitzpatrick
