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:

This is very much appreciated but I find Travis CI just confusing in the difficulty of specifying what compilers/versions should be run on which OSs, and what is actually available to test. I can of course try to work with the travis.yml in the link above. There are now your .travis.yml, Bruno's .travis.yml based on your original solution using boostdep, and Rene's solution. I appreciate everything everyone has done but I feel I will be spending too much time on a product ( Travis CI ) for which I understand little, which is difficult to use, and whose documentation is appalling. I just have better things to do ( like programming <g> ) than to joust with Travis CI. I understand of course that is is "free" but I don't see it as a good solution to continuous testing.

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.)
