Hi Chris,

If you are using a precompiled version of NCL, it's possible you have
one that was compiled with g95, and it needs g95's "f95" library
(libf95.a) in order to resolve the symbols it's complaining

You have a couple of options: you can download a g95 binary from in order to get this f95 library, and then include
"-lf95" on the compile line, or else you can build NCAR Graphics from
source code yourself, using whatever Fortran compiler you have.

Good luck,
