Travis CI examples


Travis CI Continuous Integration service (self-check code on each git push) has free private builds for educational users, and free public builds for all.

Free continuous integration

These CI services are free for public repositories. Some have usage limits (e.g. minutes/month). Even for unlimited services like Travis CI, I cancel build jobs if I make git push in quick succession to save their resources from unneeded builds I know have errors. A git commit including [ci skip] will not CI build, that seems to be a de facto standard.

Travis-CI can compile in almost any language, for Linux, Mac and Windows, with various compiler versions.

Here are a few categories of simple multi-platform builds.

Python + Fortran

Python compiling 40 year old Fortran code: .travis.yml

C + HDF5 + Cmake

IPv6 C with HDF5 writing and Cmake: .travis.yml

C++ + Cmake

C++ and Cmake: .travis.yml


IDL or GDL GNU Data Language: .travis.yml
