Re: produce *mod with fortran

[Eve-Marie Devaliere]

I am sorry I think I figured out my own typo... it should be FCFLAGS not
FC_FLAGS... (For some reasons they had FC_FLAGS in their original program)
Now if I export FCFLAGS before running configure I can't even configure
; it is saying
checking whether the Fortran compiler works... configure: error: cannot
run Fortran compiled programs.
????
This is very strange... I tried to reset FC to ifort to make sure but no
luck....
If I export FCFLAGS again with -g ; (it configures again but make
doesn't work)
