> Description of problem: * I am trying to compile netcdf for g95. The first
step - configure - works with no options, using pgf90. However, when I set
F90=g95, FC=g77, CC=gcc, I run into the error:

Set FC=g95, and leave F90 unset. That will use g95 for both the F77 and F90
APIs.

If you really do want to use g77 for the F77 API, set F77=g77 and F90=g95.

Good luck,

Ed
