This is a short demo of the fortran support in libtool. fprogram is a pure-fortran program which is linked against the fortran-only library libfoo.la cprogram is a C program, which is linked against the mixed C and fortran library libmix.la. The program calls a C function, which in turn calls a fortran function. This demo requires GNU autoconf, automake, libtool with the FC tag and quite obvious Fortran.
