<div dir="ltr">Folks,<div><br></div><div>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)<br clear="all"><div><br></div><div>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)</div>
<div><br></div><div>(it's py_enchant, if anyone is interested: <a href="http://pythonhosted.org/pyenchant/">http://pythonhosted.org/pyenchant/</a>)</div><div><br></div><div>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?)</div>
<div><br></div><div>Usually, a binary wheel involves compiled extensions, and thus is tied to a particular python version -- so this is an odd case.</div><div><br></div><div>We tried:</div><div><br></div><div><span style="font-family:arial,sans-serif;font-size:12.800000190734863px">pyenchant-1.6.6-py2.py3-none-</span><span style="font-family:arial,sans-serif;font-size:12.800000190734863px">macosx_10_6_intel.whl </span><br>
