This is difficult - fortran modules are a PITA from a build perspective. Many compilers don't seem to have a way to control exactly where to put the generated .mod, so the only way I am aware of to control this is to cwd the process into the build directory... This was also a problem when I worked on fortran support for waf (see http://groups.google.com/group/waf-users/browse_thread/thread/889e2a5e5256e420/84ee939e93c9e30f?lnk=gst&q=fortran+modules#84ee939e93c9e30f ) > > My problem is in instantiating numpy.distutils.config such that it is > appropriately configured with command line flags. > > I've tried the following with no success: > > ('self' is a build_ext instance) > cfg = self.distribution.get_command_obj('config') > cfg.initialize_options() > cfg.finalize_options() # doesn't do what I hoped it would do. > > This creates a config object, but it doesn't use the command line > flags (e.g. --fcompiler=gfortran doesn't affect the fortran compiler > used). Why don't you do the testing in config ? That's how things are done normally, unless you have a reason to do otherwise. Concerning the --fcompiler option, how do you pass --fcompiler (what is the exact list of commands you used to call distutils here) ? Generally, given the general command/option screw up, the only real solution really is to pass the options to each command, and hope each one is the same. > Any pointers?

Not really, that's how you are supposed to do things with distutils, David _______________________________________________ NumPy-Discussion mailing list [email protected] http://mail.scipy.org/mailman/listinfo/numpy-discussion
