Continuous Integration

Here you will find snippets to use Meson with various CI such as Travis and AppVeyor.

Please file an issue if these instructions don't work for you.

Travis-CI with Docker

Travis with Docker gives access to newer non-LTS Ubuntu versions with pre-installed libraries of your choice.

This yml file is derived from the configuration used by Meson for running its own tests.

os:
  - linux
  - osx

language:
  - cpp

services:
  - docker

before_install:
  - if [[ "$TRAVIS_OS_NAME" == "osx" ]]; then brew update; fi
  - if [[ "$TRAVIS_OS_NAME" == "osx" ]]; then brew install python3 ninja; fi
  - if [[ "$TRAVIS_OS_NAME" == "osx" ]]; then pip3 install meson; fi
  - if [[ "$TRAVIS_OS_NAME" == "linux" ]]; then docker pull YOUR/REPO:eoan; fi

script:
  - if [[ "$TRAVIS_OS_NAME" == "linux" ]]; then echo FROM YOUR/REPO:eoan > Dockerfile; fi
  - if [[ "$TRAVIS_OS_NAME" == "linux" ]]; then echo ADD . /root >> Dockerfile; fi
  - if [[ "$TRAVIS_OS_NAME" == "linux" ]]; then docker build -t withgit .; fi
  - if [[ "$TRAVIS_OS_NAME" == "linux" ]]; then docker run withgit /bin/sh -c "cd /root && TRAVIS=true CC=$CC CXX=$CXX meson builddir && ninja -C builddir test"; fi
  - if [[ "$TRAVIS_OS_NAME" == "osx" ]]; then SDKROOT=$(xcodebuild -version -sdk macosx Path) meson builddir && ninja -C builddir test; fi

CircleCi for Linux (with Docker)

CircleCi can work for spinning all of the Linux images you wish. Here's a sample yml file for use with that.

version: 2.1

executors:
  # Your dependencies would go in the docker images that represent
  # the Linux distributions you are supporting
  meson_ubuntu_builder:
    docker:
      - image: your_dockerhub_username/ubuntu-sys

  meson_debian_builder:
    docker:
      - image: your_dockerhub_username/debian-sys

  meson_fedora_builder:
    docker:
      - image: your_dockerhub_username/fedora-sys

jobs:
  meson_ubuntu_build:
    executor: meson_ubuntu_builder
    steps:
      - checkout
      - run: meson setup builddir --backend ninja
      - run: ninja -C builddir
      - run: meson test -C builddir

  meson_debian_build:
    executor: meson_debian_builder
    steps:
      - checkout
      - run: meson setup builddir --backend ninja
      - run: ninja -C builddir
      - run: meson test -C builddir

  meson_fedora_build:
    executor: meson_fedora_builder
    steps:
      - checkout
      - run: meson setup builddir --backend ninja
      - run: ninja -C builddir
      - run: meson test -C builddir

workflows:
  version: 2
  linux_workflow:
    jobs:
      - meson_ubuntu_build
      - meson_debian_build
      - meson_fedora_build

AppVeyor for Windows

For CI on Windows, AppVeyor has a wide selection of default configurations. AppVeyor also has MacOS and Linux CI images. This is a sample appveyor.yml file for Windows with Visual Studio 2015 and 2017.

image: Visual Studio 2017

environment:
  matrix:
    - arch: x86
      compiler: msvc2015
    - arch: x64
      compiler: msvc2015
    - arch: x86
      compiler: msvc2017
    - arch: x64
      compiler: msvc2017

platform:
  - x64

install:
  # Set paths to dependencies (based on architecture)
  - cmd: if %arch%==x86 (set PYTHON_ROOT=C:\python37) else (set PYTHON_ROOT=C:\python37-x64)
  # Print out dependency paths
  - cmd: echo Using Python at %PYTHON_ROOT%
  # Add necessary paths to PATH variable
  - cmd: set PATH=%cd%;%PYTHON_ROOT%;%PYTHON_ROOT%\Scripts;%PATH%
  # Install meson and ninja
  - cmd: pip install ninja meson
  # Set up the build environment
  - cmd: if %compiler%==msvc2015 ( call "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" %arch% )
  - cmd: if %compiler%==msvc2017 ( call "C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build\vcvarsall.bat" %arch% )

build_script:
  - cmd: echo Building on %arch% with %compiler%
  - cmd: meson --backend=ninja builddir
  - cmd: ninja -C builddir

test_script:
  - cmd: ninja -C builddir test

Qt

For Qt 5, add the following line near the PYTHON_ROOT assignment:

 - cmd: if %arch%==x86 (set QT_ROOT=C:\Qt\5.11\%compiler%) else (set QT_ROOT=C:\Qt\5.11\%compiler%_64)

And afterwards add %QT_ROOT%\bin to the PATH variable.

You might have to adjust your build matrix as there are, for example, no msvc2017 32-bit builds. Visit the Build Environment page in the AppVeyor docs for more details.

Boost

The following statement is sufficient for meson to find Boost:

 - cmd: set BOOST_ROOT=C:\Libraries\boost_1_67_0

Travis without Docker

Non-Docker Travis-CI builds can use Linux, MacOS or Windows. Set the desired compiler(s) in the build matrix. This example is for Linux (Ubuntu 18.04) and C.

dist: bionic
group: travis_latest

os: linux
language: python

matrix:
  include:
    - env: CC=gcc
    - env: CC=clang

install:
  - pip install meson ninja

script:
  - meson builddir
  - ninja -C builddir
  - ninja -C builddir test

GitHub Actions

GitHub Actions are distinct from Azure Pipelines in their workflow syntax. It can be easier to setup specific CI tasks in Actions than Pipelines, depending on the particular task. This is an example file: .github/workflows/ci_meson.yml supposing the project is C-based, using GCC on Linux, Mac and Windows. The optional on: parameters only run this CI when the C code is changed--corresponding ci_python.yml might run only on "**.py" file changes.

name: ci_meson

on:
  push:
    paths:
      - "**.c"
      - "**.h"
  pull_request:
    paths:
      - "**.h"
      - "**.h"
