How to make Travis CI test package for Linux, OS X, Windows?

If anyone is looking for a working, Windows/Mac/Linux python configuration example, see this repository: https://github.com/cclauss/Travis-CI-Python-on-three-OSes

Update 3

Windows support has been released! You can now use Travis CI with Linux, macOS, and Windows. You can find their blog post about it here.

Update 2

This feature is enabled now (no need to send request to Travis team). Though still considered beta:

• Multi-OS

Works fine for me, here is Linux + OSX configuration:

• .travis.yml
• build matrix

Windows support still in progress (see windows issues) as alternative AppVeyor can be used. Example of configuration file:

• appveyor.yml

Update

• Multi-OS beta testing

There is an open issue for Travis CI:

• Issue #216

As a workaround for Linux + Mac OS X you can create two branches. One with default config (for Linux) and one with objective-c language (for Mac OS X).
