Demo project for building Python wheels for Linux with Travis-CI

Build Status

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 Docker Repository on Quay
  • 32-bit image (i686): quay.io/pypa/manylinux1_i686 Docker Repository on Quay

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.
