Has anyone added any FORTRAN support since the version of Distutils that came with python 2.0? I tried compiling Multipack with Distutils (after setting up the source with modified versions of the Makefile and setmodules.py from the Multipack distribution) by subclassing from UnixCCompiler, but of course that only works if you do it in two steps:

./setup.py build_clib -c unixf

./setup.py build_ext

Actually of course with g77 (FORTRAN front-end to gcc) it will work with just ./setup.py build -cunixf because g77 will happily do C too. Presumably this doesn't apply to many (any?) other compilers, though. Oddly though, after you've built your extensions and libraries, this *doesn't* work: ./setup.py install as it will default to the compiler named 'unix' (ie. unixccompiler.py), see that things aren't up to date from its point of view (not sure exactly why, but presumably because the compiler has changed), and try to compile the FORTRAN with a plain 'gcc -c' command which fails, of course. You can't do this: ./setup.py install -cunixf because there is no -c option for the install command.

where unixf is my added FORTRAN compiler. I suppose the right thing would be to put it in CCompiler itself, so that all its subclasses would be capable of compiling FORTRAN too (with appropriate modifications)?

For the case of gcc, I should have been able to do this by just telling Dustutils to substitute g77 for gcc, add a new list of file prefixes for source (".f" etc), and not modify the source at all - shouldn't this be possible via the command line? I know it is the intention eventually to drive that sort of thing from an autoconf-style thing, but in the mean time, it would seem to be useful to be able to change at least the executable names via the command line / config file - or have I missed the option that does this?

I suppose the same would be true of, eg Pascal too. Maybe the class needs renaming too... [...]
