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): dockcross/manylinux-x64 Docker Repository on DockerHub
• 32-bit image (i686): dockcross/manylinux-x86 Docker Repository on DockerHub

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/dockcross/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 wheels, the build script runs the wheels through auditwheel, which copies the external library into the wheel itself, so that users won't need to install any extra non-PyPI dependencies.
