Re: Problem building Fortran program with g77

["Tim Prince" <tprince at computer dot org>]

libg2c.a is certainly required, and a normal g77 installation would be
looking for it in the same way as if you had specified 'gcc *.o -lm'.  so it
is expected to be in the gcc library path.  It should be provided in any
binary installation of g77; the source is included in the gcc/g77 source
distributions and will install automatically when you build and install g77.
It is non unheard of for linux distros to omit libg2c.a, and there the most
straightforward way out is to build and install from source.
