Today I was working on adding Travis-CI support to my project MINX and I came across an issue that had happened to several people, but no single source had the solution. I compile MINX with g++ (just because that's what I'm used to). A few things inside of MINX require C++11 so I'd normally just add a * -std=c++11 * argument in my makefile.
To my surprise the virtual machines that Travis-CI uses have g++ 4.6 installed, this is an issue for anyone who wants track the build status of a C++11 program with Travis. After a few minutes of searching I came across a link that provided me with an Ubuntu tools PPA that contained some newer versions of g++. Below I've included a few lines that will allow you to use * -std=c++11 * with g++ for your .travis.yml file:
language: cpp
before_install:
# We need this line to have g++4.8 available in apt
- sudo add-apt-repository -y ppa:ubuntu-toolchain-r/test
- sudo apt-get update -qq
install:
- sudo apt-get install -qq gcc-4.8 g++-4.8
# We want to compile with g++ 4.8 when rather than the default g++
- sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.8 90
