burningdaylight/docker-mingw-qt5 repository overview

⁠MinGW-arch

mingw-based build environment based on arch-linux. The image provides an easy to use cross-compilation for windows target. It is also CI-friendly. mingw- versions of Qt5, cmake, Eigen3, boost are included. Dosens of other libraries⁠ are available from the package manager.

⁠Usage

Start the docker container:

sudo docker run -it burningdaylight/mingw-arch:qt /bin/bash

Compile your application (QNapi is used as an example here):

git clone --recursive 'https://github.com/QNapi/qnapi.git'
cd qnapi/
x86_64-w64-mingw32-qmake-qt5
make

Or for CMake:

x86_64-w64-mingw32-cmake ..

To deploy the program, you will need to copy the dlls from /usr/{x86_64-w64-mingw32,i686-w64-mingw32}/{bin,lib/qt/plugins/{imageformats,iconengines,platforms}} (for x64 and x32 builds respectively) to the directory with the .exe file. The list of necessary dlls may vary. If a dll is missing, Windows will usually show an error popup window with the name of the missing dll, when you try to start the program.

That's it!

⁠Continuous Integration

For Gitlab CI the config file could look something like this:

build-win64:
  stage: compile
  image: burningdaylight/mingw-arch:qt
  script:
    - mkdir -p ${CI_BUILD_NAME}
    - cd ${CI_BUILD_NAME}; x86_64-w64-mingw32-qmake-qt5 ..; make
  artifacts:
    paths:
      - "${CI_BUILD_NAME}/src/*/release/*.exe"
      - "${CI_BUILD_NAME}/src/*/release/*.dll"

You can also check out the a full .gitlab-ci.yml⁠ file.

⁠Dependencies

If you need some other dependencies, you can install them from AUR⁠.

yay -S --noconfirm mingw-w64-rapidjson

If mingw- version of the needed libarary is not available in AUR, you can add it yourself. The process is really straightforward. You would need to write a PKBUILD file⁠, which is as intuitive as it can get, see mingw-w64-rapidjson⁠, for example.

⁠Supported tags

• base minimal cross-compilation environment which includes yay to install additional libraries from AUR and a small set of mingw-w64- packages: cmake, gcc, zlib
• latest, qt full-blown cross-compilation environment, which includes Qt5, boost, openssl, etc.
