Building NetCDF fortran90 libraries on Macintosh OS X

Here are directions for building netcdf with all fortran 90 features on Macintosh OS X 10.2 using the NAG f95 compiler. make test runs successfully through all tests.

1. Define the variables:

   setenv FC /usr/local/bin/f95
   setenv FFLAGS "-O -dusty -w"
   setenv F90 /usr/local/bin/f95
   setenv FPP "/usr/local/bin/f95 -fpp"
   setenv F90FLAGS "-O -w=unused -mismatch_all"
   setenv CPPFLAGS "-DNAGf90Fortran"
   

2. Run

   configure <--prefix=installation_directory>

3. OS X is case insensitive, which causes problems with .F files. To work around, modify the .F.o rule in the rules.make file. It should read like this:

   # Not all FORTRAN compilers support C-preprocessing of *.F files; ergo, a
   # relatively complicated rule ensues.
   .F.o:
           @case "$(COMPILE.F)" in \
               '') \
                   set -x; \
                   cp $*.F $*.ff; \
                   $(FPP) $(FPPFLAGS) -c -O -dusty -w $*.ff ;      \
                   ;;      \
               *)  \
                   set -x; \
                   $(COMPILE.F) $<;        \
                   ;;      \
           esac
   

4. Add this line to the file nf_test.F in the directory nf_test, after the program nf_test statement:

     USE F90_UNIX_ENV, ONLY : IARGC,GETARG 

   (this will define iargc and getenv) comment out this line:

      integer         iarg

   (conflicts with f90_unix_env)

5. Run

   make

   and

   make test

6. Run

   make install

7. manually copy src/f90/netcdf.mod src/f90/typesizes.mod to /usr/local/include, or wherever the installation is supposed to go.
