Hi Karsten,

I'm glad its working.

And just for reference sake, heres what happened:

 1) An unhelpful sysadmin compiled netcdf with some unknown 
    and g77-incompatible compiler and then installed it in a 
    system-wide default location.

 2) Karsten tried to use g77 which then automatically found the
    incompatible library (with "-lnetcdf") and it tried and 
    failed to link against it.

 3) Karsten then solved the problem by installing his own g77-
    compatible version of netcdf using the commands:

    $  cd $HOME
    $  wget ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-3.5.1.tar.Z
    $  tar -xzf netcdf-3.5.1.tar.Z
    $  cd netcdf-3.5.1/src
    $  export CPPFLAGS="-DNDEBUG -Df2cFortran -fPIC"
    $  export CFLAGS="-Df2cFortran -fPIC"
    $  export FC="g77"
    $  ./configure
    $  make
    $  cp libsrc/libnetcdf.a libsrc/libnetcdf_g77.a

    and then created a custom MITgcm optfile that contained 
    the lines:

      INCLUDES="-I$HOME/netcdf-3.5.1/src/fortran"
      LIBS="-L$HOME/netcdf-3.5.1/src/libsrc -lnetcdf_g77"

    where $HOME is Karsten's home directory.


I just wanted to make sure that this was documented since the above
approach will, with just a few small changes, work for any compiler.

Ed
