I am running Mac OS X 10.7.3 (Lion)
I have a problem in using the fortran compiler g77: any program I try to compile, it gives me this message: "g77: installation problem, cannot exec `as"
I've downloaded and installed the latest release of Xcode, but nothing changed…
Thanks in advance for any help,
Marco

g77 is not part of Xcode. You may have a look here http://hpc.sourceforge.net/ which provides a version compatible with Lion and XCode 4.x.
