I'm running iraf:

NOAO/IRAF PC-IRAF Revision 2.16 EXPORT Thu May 24 15:41:17 MST 2012
This is the EXPORT version of IRAF V2.16 supporting PC systems.

under OS X Yosemite ver. 10.10.5 on a MacBook Pro 2.8 GHz Intel Core i7

and am trying to compile a fortran program. I am getting the following error message:



dopitafits22018.f:
MAIN dopitafits22018:
dopitafits22018.c:478:1: warning: control reaches end of non-void function [-Wreturn-type]
} /* MAIN__ */

dopitafits22018.c:480:63: warning: control reaches end of non-void function [-Wreturn-type]
/* Main program alias */ int dopitafits22018_ () { MAIN__ (); }
^
2 warnings generated.
link:
Undefined symbols for architecture x86_64:
"_abualogq_", referenced from:
_MAIN__ in dopitafits22018.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I gather the warnings can be ignored, but the other messages cause the program not to crete an executable file. I have no parameter called abualogq in the fortran program.

Any thoughts?

Thanks.
