However, it has some drawbacks: integrate Spack explicitly in their workflow. Not all users are willing to do this. +------------------------ +Using Spack on Travis-CI +------------------------ + +Spack can be deployed as a provider for userland software in +`Travis-CI <https://http://travis-ci.org>`_. + +A starting-point for a ``.travis.yml`` file can look as follows. +It uses `caching <https://docs.travis-ci.com/user/caching/>`_ for +already built environments, so make sure to clean the Travis cache if +you run into problems. + +The main points that are implemented below: + +#. Travis is detected as having up to 34 cores available, but only 2 + are actually allocated for the user. We limit the parallelism of + the spack builds in the config. + (The Travis yaml parser is a bit buggy on the echo command.) + +#. Builds over 10 minutes need to be prefixed with ``travis_wait``. + Alternatively, generate output once with ``spack install -v``. + +#. Travis builds are non-interactive. This prevents using bash + aliases and functions for modules. We fix that by sourcing + ``/etc/profile`` first (or running everything in a subshell with + ``bash -l -c '...'``). + +.. code-block:: yaml + + language: cpp + sudo: false + dist: trusty + + cache: + apt: true + directories: + - $HOME/.cache + + addons: + apt: + sources: + - ubuntu-toolchain-r-test + packages: + - g++-4.9 + - environment-modules + + env: + global: + - SPACK_ROOT: $HOME/.cache/spack + - PATH: $PATH:$HOME/.cache/spack/bin + + before_install: + - export CXX=g++-4.9 + - export CC=gcc-4.9 + - export FC=gfortran-4.9 + - export CXXFLAGS="-std=c++11" + + install: + - if ! which spack >/dev/null; then + mkdir -p $SPACK_ROOT && + git clone --depth 50 https://github.com/llnl/spack.git $SPACK_ROOT && + echo -e "config:""\n build_jobs:"" 2" > $SPACK_ROOT/etc/spack/config.yaml; + fi + - travis_wait spack install cmake@3.7.2~openssl~ncurses + - travis_wait spack install boost@1.62.0~graph~iostream~locale~log~wave + - spack clean -a + - source /etc/profile && + source $SPACK_ROOT/share/spack/setup-env.sh + - spack load cmake + - spack load boost + + script: + - mkdir -p $HOME/build + - cd $HOME/build + - cmake $TRAVIS_BUILD_DIR + - make -j 2 + - make test + ------------------ Upstream Bug Fixes ------------------ |
