This repository describes a podman/docker container that can simplify building Krita from source.

Usage

First, you'll need a copy of the Krita source tree. You can get this from the Krita website: https://krita.org/en/download/krita-desktop

Also, you probably want to create a "build" directory where CMake will store its build system and generated artifacts. Krita takes a long time to build from scratch, but reusing the build directory speeds up the process significantly on subsequent rebuilds. See cmake(1) for more information.

Assuming your Krita sources are located in ./src, your build directory is ./build, and the directory where you want Krita to be installed after building is ./install, the following command will build Krita with the default options:

podman run -it \
       --env CMAKE_INSTALL_PREFIX="$PWD/install" \
       --mount type=bind,src="$PWD/src",dst=/krita/src \
       --mount type=bind,src="$PWD/build",dst=/krita/build \
       --mount type=bind,src="$PWD/install",dst=/krita/install \
       --userns=keep-id \
       localhost/krita-build

The CMAKE_INSTALL_PREFIX variable should contain the path where Krita will be installed and run from. This means the final executable should end up at "$CMAKE_INSTALL_PREFIX/bin/krita".

After the build finishes, you should be able to run Krita:

./install/bin/krita

Invoking podman by hand is a bit of work, so there's also a run.sh script to make this easier.
