Wheels and custom PyPI #16

Closed nimish closed 7 years ago

nimish commented 7 years ago

Hi,

It looks like wheels for each supported platform would be better than the current method of unpacking a tar.gz on build. I can construct one using bdist_wheel, but it's missing the right metadata on platform and ABI, and would be a lot easier if they were pre-constructed somewhere, since the code is already compiled.

Hi,

I perfectly agree. The current method leaves a lot to be desired, and in fact we have Conda packages (with prebuilt binaries, much like wheels). I am at the moment investigating if wheels are an option - as usual this is more about license-conflicts than about technical problems.

Yes, I doubt that the regular PyPI would like the existing license, but it would make a lot of sense to have a custom "pypi.mosek.com" for licensees. Just food for thought :)

I have made some experiments with Wheels. It seems that wheels have no way to handle shared library dependencies (in our case we rely on the solver library and a threading library). I will look into hosting packages, but unless i find a way around the library problem it may have to be a setup.py bases installer.

@ulfworsoe Hmm, that's going to be difficult...the only solution i know of, and only for linux, is https://pypi.python.org/pypi/auditwheel

Other options are using CFFI and having the shared libs be included

Mostly addressed by https://github.com/MOSEK/Mosek.pip/pull/19 ; wheels do not have the correct platform info, but changing that would need some changes in the core mosek python code.
