Hi, I had troubles with distutils 1.0 and the way I use SWIG. I couldn't find any support for the -shadow option and no way to pass an extra include dir to swig (like it´s possible for the c compiler) Therefore I wrote a patch. It adds an extra_swig_args (list of string) option to Extension. All the strings are passed to swig without modification, but if extra_swig_args contains "-c++" or "-shadow" there is some special action: "-c++": behaves like build_ext --swig-cpp "-shadow": Normally swig generates a file: foo.c -> foo.so In this case SWIG generates two files: foo.py (python shadow classes, imports fooc) fooc.c -> fooc.so With this patch build_ext can handle this und generates for foo.i (foo.py, fooc.c) compiles them and installs them. Below is the diff against disutils 1.0, apply in your Distutils-1.0 directory with: patch -p5 < file I hope it doesn´t break anything, isn´t against distutils design principles and is so useful that it might become part of distutils. Please answer me directly, because I didn´t not subscribe ths list.
