error: f2c.h: No such file or directory

Hi,

I'm trying to compile any external packages and I keep getting tripped by the f2c.h file not being found. The file is in /astro/iraf/macintel-10.6/iraf/iraf-v2.14.1/unix/bin.macintel/f2c.h . I have checked that iraf, IRAFARCH are set. I also source irafuser.csh.

Mac OS X 10.6 (snow leopard)
> uname -a

I have been able to compile on snow leopard on another machine which I suspect had f2c.h somewhere else (un-verified).

My question I guess is how can I get IRAF to find its own f2c.h? Shouldn't it find it on its own?

Thanks for your help!
Kathleen

Set the what values exactly? And in which file? If you're compiling from a mkpkg then the XC gets spawned and your .cshrc file is used, but if you're compiling with XC directly then it uses whatever is in your shell environment and/or perhaps what was defined (differently?) in your .login file.

The f2c.h file needed by iraf is normally found on its own with a '-I' flag set in the hlib$f77.sh script, that path is build from whichever $iraf and $IRAFARCH is in play. If you edit the f77.sh script so there's a '-x' aarg on the first line it will trace the script and you can see what it is doing, compiling a simple hello.x file is all you need.

$iraf is set to /astro/iraf/macintel-10.6/iraf/iraf-v2.14.1/
$IRAFARCH is set to macintel
The .cshrc is the one that comes with as.pcix.gen, save a correction for $iraf and the $PATH. Same for .login.

I am using mkpkg. I'm doing the same as I have always done:

cd color
setenv color `pwd`/
mkpkg macintel
mkpkg -p color update |& tee spool

----
add -x arg to f77.sh: you mean on the #!/bin/sh line?

PROBLEM SOLVED!

I had CFLAGS defined and it seems that the system doesn't just append to the variable but takes it as it is when already defined.

Thanks for the -x in f77.sh trick. Very useful outputs.
