--- Comment #10 from Daan van Vugt <daanvanvugt at gmail dot com> --- (In reply to Steve Kargl from comment #8) > Thanks. Can you add the -v option to the above command line > and report the output (up to the ld line)? Do you have > more than one version of gfortran installed? No other versions of fortran are installed. Driving: gfortran -v -g read_urandom.f90 -o read_urandom -l gfortran -l m -shared-libgcc Using built-in specs.
