The fact that 'fc' is being called tells me that someone there downloaded
the new mcupdate.tar.Z file recently.  It also implies that there is either
an old version of makefile (likely since you are playing with it) and a
new version of 'mccomp' (generated by make from the mccomp.sh template)
or some other unknown problem.  I expect that the problem is that you are
did get the new mcupdate.tar.Z file and have been using an old (pre-latest
update) makefile.  The reason for my conjecture is that the only way that
'mccomp' will try to use 'fc' as the Fortran compiler is if you are using
the new mccomp.

So, what you should do is modify the copy of 'makefile' that you are using
in the and make sure that yours has the following code:

#-------
# General macros.
#-------

INCARGS         = -I.

STRIP           = -s
# STRIP         =

# DEBUG         = -g
DEBUG           =

# BFC           = -f2c bfc
BFC             =

COMPILERS       = -vendor
# COMPILERS     =

The thing that is likely to have changed is the addition of the COMPILERS
macro.  This was added so that we can support use of gcc/f2c on Sun
Solaris.

This is the same problem as above.

The error related to 'fc' negates all of the following possible problems.

OK, this pretty much proves that the COMPILERS macro code is not in the
copy of makefile that you are using.

OK, good.

The object code for program files is not put into the library.  Only subroutine
object code is put into the library.

>Probably not a good idea.

Since wfgimnt.o and lisgix.o were probably not in the library, this wouldn't
do anyting.

>5. I tried compiling wfgimnt, which obviously didn't work because the makefile

The question is whether or not the version of makefile that you are using
has the COMPILERS macro code?

>6. I tried again to compile wfgimnt and lisgix, which generated the following

Same problem as above.  With COMPILERS set to -vendor, and with the new
version of 'mccomp' (generated by you by running 'make mccomp'), the compilation
lines would look like:

f77 -c -O wfgimnt.f

and

f77 -c -O lisgix.f

The fix should be very easy.  Simply edit ~mcidas/mcidas7.4/src/makefile
and add the COMPILERS macro code exactly as I listed above.  Then
insure that you have a new copy of 'mccomp' by running 'make mccomp'.
After that, you should do:

rm wfgimnt.o lisgix.o
make wfgimnt.k lisgix.k

>Thanks a bundle,

Let me know if you run into problems.
