It's also possible you no longer need libg2c: it (IIRC) is for g77 the old Fortran implementation that has been replaced by gfortran. (That said you may need to link something else instead for gfortran but I don't know enough about it.) The one you found on disk: > > /usr/lib/gcc-lib/i386-redhat-linux/3.2.3/libg2c.so > > /usr/lib/gcc-lib/i386-redhat-linux/3.2.3/libg2c.a is for the old compatibility compiler: Fedora Core 5's system compiler is gcc 4.1 not 3.2.3. Or you could try building your program with that compiler instead. Rup.
