It's less of an issue on Windows, since we're already assuming python.orgbinary compatibility in most cases anyway. However, I'll have a look and see if this info is exposed any other way. > We also need to update the PEP/implementation to allow/add to the list > of supported tags "py2.py3-none-(arch)" for cffi-type "doesn't use the > ABI" extensions. This might just be a bug in the implementation... That's definitely supposed to be allowed by the spec, specifically for that ctypes/cffi style use case. Now, whether the tools currently provide a way to *generate* a tag like that is a different question :) Cheers, Nick. > > On Tue, Jan 28, 2014 at 5:40 AM, Nick Coghlan <[email protected]> wrote: > > Currently, bdist_wheel doesn't set the ABI tag properly on Python 2.x > > - the SOABI symbol it expects to find isn't present.
