python-manylinux-demo
Demo project for building Python wheels for Linux with Travis-CI
This is an example of how to use Travis-CI to build PEP 513-compatible manylinux1 wheels for Python. It supports both Python 2 and 3 on 32 and 64 bit linux architectures.
Because these wheels need to be compiled on CentOS 5, this example uses Docker running on Travis-CI to compile (you don't need to use docker at all to use these wheels, it's just to compile them). The docker-based build environment images are:
- 64-bit image (x86-64):
quay.io/pypa/manylinux1_x86_64 - 32-bit image (i686):
quay.io/pypa/manylinux1_i686
This sample project contains a very simple C compile extension module that links
to an external library (ATLAS, a linear algebra library). The build is
configured via the setup.py file.
Continuous integration setup with Travis + Docker
The .travis.yml file in this repository sets up the build environment. The
resulting build logs can be found at
https://travis-ci.org/pypa/python-manylinux-demo
The .travis.yml file instructs Travis to run the script
travis/build-wheels.sh inside of the 32-bit and 64-bit manylinux1 docker
build environments. This script builds the package using pip. But these
wheels link against an external library. So to create self-contained libraries,
the build script runs the wheels through
auditwheel.
Code of Conduct
Everyone interacting in the python-manylinux-demo project's codebases, issue trackers, chat rooms, and mailing lists is expected to follow the PyPA Code of Conduct.
