Setting up Linux build on Travis CI

In general, a Linux build is done by adding the following to your .travis.yml matrix build. Currently Ubuntu 14.04 is the latest you can get. See the official documentation for more information.

matrix:
  include:
  - language: cpp
    os: linux
    dist: trusty
    compiler: gcc

It's advisable to use the container builds instead of the sudo-enabled ones as they are generally much faster to boot up, however they have restrictions on what packages can be installed. Installing packages is done by adding the following to your .travis.yml

matrix:
  include:
  - language: cpp
    os: linux
    ...
    addons:
      apt:
        packages:
        - ninja-build
        - libsdl2-dev
        ...

You can find out how's the package named by searching for Ubuntu Trusty packages. The packages are whitelisted, be sure to check the ubuntu-trusty file in https://github.com/travis-ci/apt-package-whitelist before adding a package to the list. Some packages might require enabling a third-party PPA, a whitelist for them is at https://github.com/travis-ci/apt-source-whitelist. If a package is not whitelisted, you can either request it by opening an issue on these repos (prepare that it may take long to get through in some cases), or build it manually and then cache the result.

Travis supports ANSI color escape codes, so don't forget to enable colored output for Corrade::TestSuite output. It supports more than just ANSI color escaping — if you use Ninja, it will display just the condensed single-line output.
