For example, if you have g95 installed as a Fortran compiler, and are using the Mac /usr/bin/gcc, you will get this error, because g95 uses a different convention for calling C functions than is supported by /usr/bin/gcc. If you don't specify which Fortran or C compiler to use with the FC and CC environment variables before invoking the configure script, the script will just use whatever it can find installed in your PATH. > and after searching online found that they suggested using this line of > code instead, if you didn't need fortran installed. > > *FC= ./configure* That says you want to compile with no Fortran compiler, so it will not try to compile, test, or install the Fortran interface for netCDF. > as I have already got gfortran installed I thought that would be ok.

No netcdf.mod file was installed, because setting FC='' specified that you didn't want or need a Fortran interface. For MacOS X, I recommend getting gfortran and a compatible gcc, as we have tested this combination and it works fine.
