There is a new Pyfort on SourceForge. Type pyfort with no arguments to get usage info. Incompatible change required: Remove the module/end module pair of statements from your .pyf Documentation: in pdf and HTML at http://pyfortran.sourceforge.net. See the project page at http://sourceforge.net/projects/pyfortran for downloading Pyfort-6.0.tar.gz. The new version builds and installs extensions in just one line. For example, if you have created an input file mydiagostic.pfy, using Fortran library libmydiags.a located in directory /myhouse, then pyfort -i -l mydiags -L /myhouse mydiagnostic.pyf makes mydiagnostic.so and installs in Python's site-packages directory (assuming you have write permission there). It is now much easier to figure out how to add a "compiler id" for a new platform. I wouldn't say it is completely easy, but it is "easier". I hope people will post patches to fortran_compiler.py to add their favorites. I have only tested the Linux g77 / pgf77 combinations. pgf90 (Portland Group F90, Linux), g77alpha (g77 on an alpha chip)and solaris (Sun Solaris Fortran) "should" work. Numeric Python, and 0.9 or better Distutils are assumed; see documentation for details.
