Thanks! (I'm rather new to Fortran...) Ideally one should be able to point Cython to a Fortran library and start using it automatically. A good solution then seems to be to have Cython generate a Fortran 2003 wrapper around Fortran code (of any dialect), retyping the arguments as the ISO C types. However one would still need some hint about which C types correspond to which Fortran types (in size, though they won't be the same type) to be able to generate such a wrapper automatically? Any ideas? (I suppose worst-case is that we can ship a configure script which generates an include-file with the right definitions) -- Dag Sverre _______________________________________________ Cython-dev mailing list [email protected] http://codespeak.net/mailman/listinfo/cython-dev
