Hi, I would like to use gfortran in 64 bit mode, but I couldn't find any compiler option that enables it. Doing gfortran -m64 ... doesn't produce a 64 bit program (on Xeon/SuSE 10.1 x86_64). Thanks, Fred __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
