Compile your fortran file with gfortran --f2c --free-form -shared -O2 FILE.f -o LIB.so -fPIC testet on Debian unstable with ruby 1.8.4 (2005-12-24) [i486-linux] GNU Fortran 95 (GCC 4.0.3 20060212 (prerelease) (Debian 4.0.2-9)) evil.rb seems to be neccessary only in case you have output parameters and arrays on the fortran side of life. :) Cheers, Steph.
