I'm strongly -1 on this. If we ever do this, it will be impossible for a mpi4py release to ship the generated C sources... Cython will be required at build time to generate the C sources, plus some 'configure'-like step to figure out the right C type in order to hot-fix the Cython code, and all that implemented in pure distutils (you likely know how hard that is) for maximum compatibility... -- Lisandro Dalcín --------------- Centro Internacional de Métodos Computacionales en Ingeniería (CIMEC) Instituto de Desarrollo Tecnológico para la Industria Química (INTEC) Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET) PTLC - Güemes 3450, (3000) Santa Fe, Argentina Tel/Fax: +54-(0)342-451.1594 _______________________________________________ Cython-dev mailing list [email protected] http://codespeak.net/mailman/listinfo/cython-dev
