OSX build fails (TLS version error)

[TheBB]

Hi,

I tried following the instructions here, which work fine for Linux, but seem to fail on OSX. Example: https://travis-ci.org/sintefmath/Splipy/jobs/370590848

This seems related to #57 which claims to be fixed, so I am sure I'm just doing something wrong here.

.travis.yml file is

language: python

matrix:
  include:
    - sudo: required
      services:
        - docker
      env:
        - PIP=pip
        - CIBW_SKIP="cp27-* cp33-*"
    - os: osx
      language: generic
      env:
        - PIP=pip2
        - CIBW_SKIP="cp27-* cp33-*"

script:
  - $PIP install cibuildwheel==0.7.1
  - cibuildwheel --output-dir wheelhouse

I do not really see what's going wrong here. Could you maybe try running it again, to see if it wasn't a weird non-reproducible error? - Probably not, but fingers crossed.

Otherwise, I'll have a look at that minimal example, because I have the feeling that it could/should be made simpler anyway...

This seems to be a setuptools issue rather than pip issue which was corrected with #57
c.f. pypa/setuptools#1320

You can try to install your dependencies using pip before building the wheel (using CIBW_BEFORE_BUILD environment variable)

[YannickJadoul]

@TheBB Does this then mean the issue is fixed, given @mayeut's comment?

[TheBB]

Sorry, I wasn't able to test it yet. I'll close this for now assuming the fix is good. Thanks everyone.

[YannickJadoul]

Thanks! Feel free to re-open if necessary.

[joerick]

btw @TheBB, CIBW_BEFORE_BUILD={pip} install . is quite common - setuptools installing the setup_requires dependencies is pretty unreliable these days.

[mayeut]

setuptools is not updated by cibuildwheel and the version installed with python 3.4 on macOS is quite old... Shall cibuildwheel install an up-to-date version of setuptools ? (manylinux images are up-to-date, don't know about windows on AppVeyor)

[YannickJadoul]

Hmmm, maybe we should do that. After all, we're also updating pip and installing wheel...

Similar, but maybe unrelated:

I am now going to try excluding Python versions below 3 altogether ...

[mayeut]

@JorjMcKie , it's unrelated to this specific issue and has been addressed in #57. You should upgrade cibuildwheel to get a proper installation of pip on macOS

[joerick]

Fixed in #71, released in 0.9.1!
