Craig,

When you say "it works", did you mean "ictrans" compiles just fine?
If so, then I think you may have just answered your own question. :-)

Using the "-nofor-main" option may be just what you need.

The best way to propagate this option to all the Makefiles is
to edit your $NCARG/config/LINUX file and add this option to your
FcOptions line (or add it if you don't already have one):

#define FcOptions    -nofor-main

Be sure to run "make Everything" again.
