New submission from Martijn <ss@kleptog.org>: Currently distutils.sysconfig.get_config_vars() has no value for CC. This means that when you try to build a C extension using distutils it breaks, because distutils internally uses get_config_vars() to determine the compiler (distutils/ccompiler.py). Attached is a patch that works for me, with this C extensions build normally (excluding cpyext problems). But this may be a layering violation, so I'll leave it to you guys to determine the correct fix. In any case it's an improvement which improves compatibility. ---------- effort: ??? files: distutils.patch messages: 2267 nosy: kleptog, pypy-issue priority: feature release: ??? status: unread title: get_config_vars has nothing for CC, while expected internally _______________________________________________________ PyPy development tracker <pypy-dev-issue@codespeak.net> <https://codespeak.net/issue/pypy-dev/issue662> _______________________________________________________
