Hello, Jeffrey, browsing the web for information about Fortran for Linux I came across your page. I am currently writing my Diplomarbeit at the Institute for Astronomy and Astrophysics at the University of Tuebingen. We recently bought the SNI F77 compiler for Linux, and I'd like to share my first impressions. Installing is easy, but can only be done as super user.
Documentation is in German only.
There are no man pages. There are a set of html pages and a set of postscript documents. It seems that SNI F77 uses gcc's libgcc. We have gcc 2.7.2.1 installed, and SNI F77 did not find that library on its own. I had to include the appropriate '-L' option to tell SNI F77 where the libgcc resides.
