How to build the docker images:

In the root of the WZ repo:

• docker build -f docker/<subdir>/Dockerfile -t <build_image_name> .

For example:

docker build -f docker/ubuntu-20.04/Dockerfile -t ubuntu .

For more information, see the documentation on docker build.

How to build Warzone 2100 using the docker image:

Beware of line ending mismatch between Windows and Linux when cloning repo.

Ubuntu

• via CMake

docker run --rm -v $(pwd):/code <build_image_name> cmake '-H.' -Bbuild -DCMAKE_BUILD_TYPE=Debug -G"Ninja"
docker run --rm -v $(pwd):/code <build_image_name> cmake --build build

Cross-compile (for Windows)

• via CMake

docker run --rm -v $(pwd):/code <build_image_name> i686-w64-mingw32.static-cmake '-H.' -Bbuild -DCMAKE_BUILD_TYPE=Debug -G"Ninja"
docker run --rm -v $(pwd):/code <build_image_name> cmake --build build --target package

This will build the full Windows (portable) installer package.

Tips

Using CMake

The examples above build DEBUG builds.

To build a Release mode build (with debugging symbols), change:

• -DCMAKE_BUILD_TYPE=Debug to:
• -DCMAKE_BUILD_TYPE=RelWithDebInfo
