and how you change the .travis.yml file to specify one of those versions ?

For an example of how to set up Travis to test on several versions of GCC and Clang, you can take a look at Metal's '.travis.yml' [5], ...

I used Bruno's .travis.yml as a starting point to create a minimal Travis configuration with a build matrix that covers several combination of g++/clang++ versions and -std settings, and you can see the result here: https://github.com/pdimov/mp11/blob/develop/.travis.yml I omitted clang-3.5 as it conflicts with the other three, and clang-3.9 as it doesn't seem to exist as a package. For a C++03 library such as iostreams, you should probably include C++03 tests as well, and test the compiler versions installed by default, by adding f.ex. - os: linux env: TOOLSET=gcc COMPILER=g++ CXXSTD=c++03 - os: linux env: TOOLSET=clang COMPILER=clang++ CXXSTD=c++03 - os: osx env: TOOLSET=clang COMPILER=clang++ CXXSTD=c++03 and you might also want to cut down on the C++14/C++1z tests, according to taste. The Linux tests are quick and generally run in parallel, but the OS X ones are slower. You could also add g++ 4.7 and 4.8 if you feel like it (the default at the moment is 4.6 if I'm not mistaken.)
