Intégration CMake dans les outils GitHub CI

Configurer Travis CI avec stock CMake

Travis CI a CMake 2.8.7 pré-installé.

Un script minimal .travis.yml pour une version source

language: cpp

compiler:
  - gcc

before_script:
  # create a build folder for the out-of-source build
  - mkdir build
  # switch to build directory
  - cd build
  # run cmake; here we assume that the project's
  # top-level CMakeLists.txt is located at '..'
  - cmake ..

script:
  # once CMake has done its job we just build using make as usual
  - make
  # if the project uses ctest we can run the tests like this
  - make test

Configurez Travis CI avec le dernier CMake

La version CMake préinstallée sur Travis est très ancienne. Vous pouvez utiliser les binaires Linux officiels pour construire avec une version plus récente.

Voici un exemple .travis.yml :

language: cpp

compiler:
  - gcc

# the install step will take care of deploying a newer cmake version
install:    
  # first we create a directory for the CMake binaries
  - DEPS_DIR="${TRAVIS_BUILD_DIR}/deps"
  - mkdir ${DEPS_DIR} && cd ${DEPS_DIR}
  # we use wget to fetch the cmake binaries
  - travis_retry wget --no-check-certificate https://cmake.org/files/v3.3/cmake-3.3.2-Linux-x86_64.tar.gz
  # this is optional, but useful:
  # do a quick md5 check to ensure that the archive we downloaded did not get compromised
  - echo "f3546812c11ce7f5d64dc132a566b749 *cmake-3.3.2-Linux-x86_64.tar.gz" > cmake_md5.txt
  - md5sum -c cmake_md5.txt
  # extract the binaries; the output here is quite lengthy,
  # so we swallow it to not clutter up the travis console
  - tar -xvf cmake-3.3.2-Linux-x86_64.tar.gz > /dev/null
  - mv cmake-3.3.2-Linux-x86_64 cmake-install
  # add both the top-level directory and the bin directory from the archive
  # to the system PATH. By adding it to the front of the path we hide the
  # preinstalled CMake with our own.
  - PATH=${DEPS_DIR}/cmake-install:${DEPS_DIR}/cmake-install/bin:$PATH
  # don't forget to switch back to the main build directory once you are done
  - cd ${TRAVIS_BUILD_DIR}

before_script:
  # create a build folder for the out-of-source build
  - mkdir build
  # switch to build directory
  - cd build
  # run cmake; here we assume that the project's
  # top-level CMakeLists.txt is located at '..'
  - cmake ..

script:
  # once CMake has done its job we just build using make as usual
  - make
  # if the project uses ctest we can run the tests like this
  - make test
