steven, You are right. beside installing Xcode from apple (which includes some version of gcc if i am right), I've just installed g77 3.4 provided by http://hpc.sourceforge.net/. they provide also a gcc package but it contains gfortran (F95). which gcc and g++ should I install then? thanks again for the help
