Ship wheel packages for Linux ?

[atodorov]

What went wrong?

How do maintainers feel about providing wheel packages for Linux? Maybe 64bit only, same Python versions for which you build the Windows wheel packages ?

[aiudirog]

Building from source is significantly easier on Linux than on Windows, which is why I implemented the wheel deployments while adding Windows support. If we are going to do it, I would tie this into #192 instead of implementing it in Travis.

I agree with @aiudirog - I'd rather not deal with writing more Travis goo.

In the interest of completeness, @atodorov, could you tell us more about your use case - specifically, is there anything that complicates either using the package manager's version or having pip build it?

[atodorov]

I am building docker images where we pip install gssapi. I don't want to have gcc or krb5-devel inside of them, just krb5-libs and the wheel package if possible.

[atodorov]

Another use case from me: building documentation on ReadTheDocs fails b/c we can't compile gssapi there

[frozencemetery]

Thanks, that's all good to know. I'm not opposed to doing this, but unfortunately it may take a while for me to get to it. Patches welcome :)

[atodorov]

@frozencemetery I will give it a try if somebody else doesn't beat me to it.

manylinux wheels are restricted to an ancient ABI (CentOS 5 or CentOS 6) and very few shared libraries. Unless you want to statically link in KRB5 and GSSAPI, it is very unlikely that you can get manylinux to work for python-gssapi

[frozencemetery]

The end result of what's in #205 now is:

HTTPError: 400 Client Error: Binary wheel 'gssapi-0.0.0.post18-cp27-cp27mu-linux_x86_64.whl' has an unsupported platform tag 'linux_x86_64'. for url: https://upload.pypi.org/legacy/

As @tiran explained above, this is because Python prefers manylinux wheels. Since we can't staticly link in krb5 because it won't pass auditwheel, we need to be using manylinux2014 wheels. (Cred store extensions are added in 1.11, so they're not in el<=6, and I don't want to provide a version of python-gssapi without them.)
