Re: NCL Installation Question ---

There could be three things going on here:

   1. You don't have gfortran installed on your system.

       If this is the case, then you will need to either install
       the version of gfortran that has libgfortran.so.1 as part of
       it, or else you will need to build NCL from source code using
       the C/Fortran compilers you do have.

   2. You have gfortran installed, but it doesn't have libgfortran.so.1.

       If this is the case, then follow the instructions in #1 above.
       I know some folks that didn't need to install a full version of
       gfortran. They simply grabbed the "libgfortran.so.1" file from
       somewhere, and put it with their current gfortran distribution.

       You may then need to set the LD_LIBRARY_PATH environment variable
       to point to the location of libgfortran.so.1. For example, if it
       is in /usr/local/gfortran/lib, then you would use one of the
       following two commands, depending on whether you already have
       a LD_LIBRARY_PATH set:

       If you already have one:

         setenv LD_LIBRARY_PATH $LD_LIBRARY_PATH:/usr/local/gfortran/lib

       If you don't have one:

         setenv LD_LIBRARY_PATH /usr/local/gfortran/lib

   3. You do have gfortran installed, and you do have
      "libgfortran.so.1".

      If this is the case, then you need to "help" ncl find the
      location of your libgfortran.so.1. See the last part of the
      instructions in #2.

Let me know if none of these help.
