Pyo3: word-count example doesn't compile on manylinux

Repository with code: https://github.com/gukoff/PyO3-manylinux-bug
One can clone it and run a one-liner to reproduce the issue.

Error:

  error: failed to run custom build command for `pyo3 v0.2.5`
  process didn't exit successfully: `/tmp/pip-sHw2jX-build/build/temp.linux-x86_64-2.7/word-count/release/build/pyo3-aea46c0f50a8070f/build-script-build` (exit code: 101)

The error does reproduce on Mac/Ubuntu Docker, pyo3 v0.2.4 and older nightly versions of rustc.
And it was working just fine a couple of weeks ago.

@fafhrd91 aren't you by chance familiar with this issue?

[fafhrd91]

looks like a problem with python paths. are you able to build project outside of docker?

[gukoff]

Yes, it builds perfectly outside of docker.

[fafhrd91]

are you able to build any c-extension inside docker?

[gukoff]

Yep. I managed to compile https://github.com/closeio/ciso8601 using the same build_wheels.sh script. So, the problem is neither in manylinux1 nor in installing rustc via rustup.sh.

[fafhrd91]

I am busy with other projects at the moment, but I’ll try to check this problem

Hi, @gukoff I had a similar problem. The problem was solved by adding a variable PYTHON_SYS_EXECUTABLE. See Look how I did it https://github.com/PushAMP/pamagent/blob/master/build-wheels.sh#L6

[gukoff]

Interesting. PYTHON_SYS_EXECUTABLE fixes the problem, but still doesn't make pyo3 compile.

This problem is now relevant for the latest nightly assemblies. As a temporary solution, you can use the last working build from March 26

rustup toolchain install nightly-2018-03-26
rustup default nightly-2018-03-26

Or use latest master with fix https://github.com/PyO3/pyo3/pull/137

@fafhrd91 Can you post a new version with a fix?

[fafhrd91]

New version is released
