Travis-CI MacOS builds (denoted
emerged from beta
in April 2013 using cloud-based Mac hardware.
In January-March 2018,
additional Travis-CI resources
were progressively brought online, completed in March 2018.
The speed for Travis-CI MacOS builds is quite fast, almost as fast to start as Linux.
.travis.yml for MacOS (including Linux) for a Fortran build that happens to use Lapack and MPI looks like:
language: minimal group: travis_latest git: depth: 25 quiet: true env: FC=gfortran addons: apt: packages: ['gfortran','liblapack-dev','libopenmpi-dev'] matrix: include: - os: linux - os: osx before_install: - brew upgrade gcc > /dev/null - brew install lapack open-mpi > /dev/null install: - cmake -B build - cmake --build build script: - ctest --test-dir build --output-on-failure
brew update step as sometimes Travis-CI will break on
brew install without first doing
brew update if the Travis-CI MacOS image hasn’t been updated in a while.
The Travis-CI status panel shows that the MacOS backlog since March 2018 is typically near zero like the Linux builds. Before 2018, the MacOS build backlog could be in the hundreds or thousands of jobs–this is no longer an issue. The Linux backlog typically stays at or near zero.
Paid Travis-CI.com customers should also experience
short wait times
of a minute or so for
