Installation fails on older Mac OSX versions

[ambrosejcarr]

Hello, thank you for building this tool! Our cellxgene application depends on fastobo, and we're running into issues when our users are attempting to install cellxgene on old versions of OS X (e.g. 10.12). That version does not ship with a rust compiler, so our installation fails.

Would you be able to build wheels for older versions of OSX? We believe that should solve the issue we're seeing. The pypi standard appears to be to support versions from 10.9 to present.

Thanks!

Hi @ambrosejcarr ,

glad this library is of use to some people, I made it simple and easy-to-use to broaden the audience of ontology consumers 😃

Currently I am building wheels for OSX using the default Travis-CI OSX image, which is Xcode 9.4.1 / macOS 10.13. I'll try to see if it's feasible to use the lowest available version , but I think it only supports macOS 10.11 onward.

Other option I'll try is to have a build script that downloads the Rust compiler locally if not available, so that users without a Rust compiler installed manually can still build from source on their local platform.

v0.9.1 now builds the OSX wheels with XCode 7.3, which should increase support of older versions. I also updated the setup script so that, if a wheel cannot be found and compilation from source is attempted, a minimal Rust compiler is used if none is available on the host machine.

Thank you! We'll update our dependencies, check that our user's installation problems are resolved, and report back.
