[ncl-install] Undefined References to _gfortran_*

[Mary Haley]

Hi Ronnie,

Since NCAR Graphics was compiled with gfortran, you need to include "- 
lgfortran" on your compile line.

If g95 can't find "libgfortran.a" then see this FAQ:

http://www.ncl.ucar.edu/FAQ/#err_msgs_008

This is for the WRAPIT program, but the same information applies here.
