Qt app的CI：使用不同的Qt版本构建

Question

我使用Travis-CI为我的简单Qt应用程序进行持续集成。 我的.travis.yml文件看起来像这样（基于这个要点 ）：

language: cpp

before_install:
  - sudo add-apt-repository --yes ppa:ubuntu-sdk-team/ppa
  - sudo apt-get update -qq
  - sudo apt-get install -qq g++ qt4-qmake libqt4-dev qt5-qmake qtbase5-dev

script: 
  - qmake -qt=qt4 -v
  - qmake -qt=qt4
  - make
  - make -k check
  - make clean
  - qmake -qt=qt5 -v
  - qmake -qt=qt5
  - make
  - make -k check

这个配置允许我在Ubuntu（Qt 4.8.1和Qt 5.0.2）中使用默认的Qt库构建我的应用程序（并运行测试）。

有没有办法用其他Qt版本（4.7.x，4.8.x，5.1.x等）构建应用程序？

灵感来自AlexandreP回答和Twofold-Qt项目的.travis.yml文件，非常感谢Stephan Binner 。

使用此.travis.yml，您将获得10个单独的构建作业 - 矩阵部分中的元素数量。 每个构建作业都将安装指定的Qt版本，并将其用于Ubuntu中的应用程序构建，Qt 4.8 - 5.7和OS X，Qt 5.5和5.7（或最新版本）。

如果您要为Windows构建应用程序，可以尝试AppVeyor CI服务。 配置示例（Qt 5.3 - 5.7）：

version: '{build}'

init:
- git config --global core.autocrlf input

environment:
  matrix:
  - QT5: C:\Qt\5.3\mingw482_32
    MINGW: C:\Qt\Tools\mingw482_32
  - QT5: C:\Qt\5.4\mingw491_32
    MINGW: C:\Qt\Tools\mingw491_32
  - QT5: C:\Qt\5.5\mingw492_32
    MINGW: C:\Qt\Tools\mingw492_32
  - QT5: C:\Qt\5.6\mingw49_32
    MINGW: C:\Qt\Tools\mingw492_32
  - QT5: C:\Qt\5.7\mingw53_32
    MINGW: C:\Qt\Tools\mingw530_32

matrix:
  fast_finish: true

before_build:
- set PATH=%MINGW%\bin;%QT5%\bin;%PATH%

build_script:
- qmake -v
- qmake -r
- mingw32-make

我在我的项目中使用这些配置 - qtcsv 。 查看更新和构建日志。

你可以通过添加这个beineri的ppa找到更多版本的Qt。 例如，可以添加版本5.4：

before_install:
  - sudo add-apt-repository ppa:beineri/opt-qt541 -y
install:
  - sudo apt-get install qt54base qt54websockets
script:
  - source /opt/qt54/bin/qt54-env.sh
