[Distutils] ctypes and shared libs, and wheels, oh my!
Folks, I'm trying to help figure out how to do binary wheels for a package that relies on ctypes and a bundles shared lib (dll, .so. etc) The trick here is that the python code is quite version and platform independent: py2 and py3, version 2.7 and 3.3+ (I think) (it's py_enchant, if anyone is interested: http://pythonhosted.org/pyenchant/) So the trick is that the binary wheel will be platform dependent, but not the code itself, so ideally we'd have one wheel, that for instance (and teh case at hand) should work on any OS-X box version 10.6 and above, with a any of python2.7, 3.3, 3.4 (an up?) Usually, a binary wheel involves compiled extensions, and thus is tied to a particular python version -- so this is an odd case. We tried: pyenchant-1.6.6-py2.py3-none-macosx_10_6_intel.whl which seems to be saying: any version of python2 or python 3, but only on macosx 10.6 but trying to install that on my machine (py2.7, os-x 10.6) gives: pyenchant-1.6.6-py2.py3-none-macosx_10_6_intel.whl is not a supported wheel on this platform. (side note: it would be really great if that could be a more useful message -- what part of the file name didn't match? I know that's a trick, as there is a whole pile of heuristics to go through, but maybe a way to dump that process would be helpful...) Now, this may, in fat be tied to CPython (I have no idea if ctypes is available on pypy or jython or IronPython...). So I tried: pyenchant-1.6.6-cp27-none-macosx_10_6_intel.whl that does, indeed, install on my system. Also: pyenchant-1.6.6-cp27.cp33-none-macosx_10_6_intel.whl works. As 2.7 is really the only py2 that much matters, no biggie, but is there a way to get 3.3 and 3.4 and ??? all at once (I don't have py3 on that machine, so didn't test that...) So: how should this be done? Is the above the best option there is?

This is in the bug tracker already. We need to add the py2-none-arch tags etc. to Pip's list.

If you insert those tags into this list, in the pip.pep425tags.get_supported() function: https://github.com/pypa/pip/blob/develop/pip/pep425tags.py#L38 then your wheel will become installable. I'd probably put it right after these: https://github.com/pypa/pip/blob/develop/pip/pep425tags.py#L78 On Wed, Jun 11, 2014 at 12:32 PM, Chris Barker chris.bar...@noaa.gov wrote: On Wed, Jun 11, 2014 at 9:09 AM, Daniel Holth dho...@gmail.com wrote: This is in the bug tracker already.

Maybe once we have the build actually working, I'll take a look at that. -Chris On Wed, Jun 11, 2014 at 12:32 PM, Chris Barker chris.bar...@noaa.gov wrote: On Wed, Jun 11, 2014 at 9:09 AM, Daniel Holth dho...@gmail.com wrote: This is in the bug tracker already.
