20040727: linking to gempak libraries question/problem

Mark,

The unresolved references are for your linker when linking fortran executables.
I'm assuming you built the GEMPAK distribution using the portland
pgf77 as well. In that case, your link line looks to be missing
fortan functions typically found in -lU77 or -lM77.

If you did not use the same compiler to build GEMPAK that you are using to
link your program, then that is the problem. If you built GEMPAK
with gcc/g77 then you should use that linker as well.

Also, I have found that the portland compiler does not allow multiple
opens on the same fortan file in the past PG 4.0. It will compile, but give
fortan "open" errors during execution. Perhaps that has been improved in later
PG releases.
