Re: [fedora-astronomy] Revised IRAF RPM

f2c. IRAF uses memory tricks that I don't know how to port to gfortran. Also for f2c to work, I had to use the original f2c.h. Fedora uses a modified f2c.h that has different bit sizes for some of the types that caused a lot of problems.

FYI ---------- Forwarded message ---------- From: Joseph Wang <joequant(a)gmail.com> Date: Sun, Jun 30, 2013 at 2:07 AM Subject: Re: Revised IRAF RPM To: debian-devel(a)liska.ath.cx I'm running 64-bit. There are unfortunately a lot of places in iraf where the bits could have gone wrong between different distributions. If you can find a way of running the iraf binary under valgrind that might give a clue as to what is going wrong. Alternatively if you can compile under debug and get a stack trace of where the error happens, that would give us some idea of what is breaking.

Do you have an account on github? If so I can get you access to https://github.com/joequant/iraf If you branch off the linux-build branch, I can pull your changes back onto that branch.

Hi Joseph and all, Joseph Wang <joequant(a)gmail.com> writes: > At https://dl.dropboxusercontent.com/u/1025783/iraf-2.16-3test.src.rpm I used this as a base to get IRAF compiled. Although I did this under Debian, I'd like to share the experiences here: * Removing pkg/vocl/readline/ leaves vocl uncompilable. To fix this, apply shared-readline.patch. * Newer xmlrpc don't have a function xmlrpc_refcount(), which breaks vendor/voclient/libsamp/librxpc compilation. shared-xmlrpc.patch fixes this. * VO is not build. This is fixed with the build-vo.patch. * I patched the build system to consequently use CC and CFLAGS. This is done with compiler-flags.patch. This allows to propagate the default flags set by the build system. Debian likes some hardening flags here, and takes some warnings as errors. The fixes for these errors are in fix_compiler_errors.patch. * Moving the libc header files caused some dependency warnings. They are fixed with the fix-libc-deps.patch. So far, IRAF compiles without errors. For the setup, I have set the $iraf variable to /usr/share/iraf/. This leads to the problem that the executables are not found since they are searched in the same directory. The patch fhs.patch fixes this, together with the compliance to freedesktop.org that I already mentioned. So far, I can start cl, ecl, and vocl and do some of the tests in the "Preliminary Test Procedure for IRAF" from 1997. Due to the lack of xgterm, I couldn' test the graphical output (ds9 works, however). What doesn't work is imcopy. Repeatedly running "imcopy dev$pix image.short" results in ecl> imcopy dev$pix image.short dev$pix -> image.short ERROR: No write permission on file (String_File) ecl> imcopy dev$pix image.short dev$pix -> image.short ERROR: FXF: EOF encountered while reading FITS file (image.short) A file "image.short.fits" is created, however it is an invalid fits file. Can you check whether this works on Fedora, or with a binary installation of IRAF? Best regards Ole P.S. My git Repository can be found at <http://anonscm.debian.org/gitweb/?p=debian-science/packages/iraf.git> The Patches are in the subdir debian/patches/.

Build iraf RPM on fedora
by Joseph Wang 05 Jun '13

I got Hello world on fedora 18. The main roadblock was that f2c.h on fedora has had the fortran types changed a bit.

At https://dl.dropboxusercontent.com/u/1025783/iraf-2.16-3test.src.rpm Major changes are: * uses local xmlrpc-c * removes external packages (reduces source package from 82M to 52M)

Script to clean up stock iraf
by Joseph Wang 02 Jun '13

Here is a script that removes the extra files in iraf. The one library that we can probably move to an external library is xmlrpc-c

IRAF/Gfortran
by Joseph Wang 01 Jun '13

gfortran supports f77, but I'm not sure that this is good f77. The piece of code is logical Memb(1) integer*2 Memc(1) integer*2 Mems(1) integer Memi(1) integer Meml(1) real Memr(1) double precision Memd(1) complex Memx(1) equivalence (Memb, Memc, Mems, Memi, Meml, Memr, Memd, Memx) common /Mem/ Memd Memi are then used to reference the memory location as pointers. The trouble is that f90 sees this as real arrays. If you have some ideas on how to make this work in gfortran let me know.
