wrong switch plus superfluous option
With the -l option, you should leave out the `lib' part of the name, and
the extension:
$ g77 File.for -llapack
maybe you also need the math library (don't know if g77 does that
automatically), and if you want your code to be optimized, you'd add an
optimization switch:
$ g77 -O2 File.for -llapack -lm
Looking at your prompt `#', it seems as though you are working as root.
This is not a good idea. Normally you only become root if you have to
for some reason, and do the rest as an `ordinary' user.
