Hi guys, This is just to let you know that with the help of Esteban and between some work together [1] [2] I was able to have Travis CI integrated with OSSubprocess and FFICHeaderExtractor [3] [4] . Both projects are built and tested under Linux and OSX. Note also that one of the projects does a lot of FFI calls to system libs like libc and the other even generates C programs, compiles them and run it. Even the OS dependencies (like installing the compiler) are resolved correctly :) If someone wants to know how it's done, simply check the .travis.yml and the scripts/run-test.sh of each project [5] [6].
