Builds on Linux use a containerised environment created using the [Dockerfile](https://github.com/eidetic-av/pointcaster/blob/qt/Dockerfile) in the root of the repository. This handles download and configuration of all dependencies. Either [Docker](https://docs.docker.com/engine/install/) or [Podman](https://podman.io/docs/installation) must be installed and configured on your system to proceed.

The Pointcaster AppImage can be built using Docker or Podman from the repository root like so:

The Pointcaster AppImage can be built from the repository root like so:
```sh
-
docker build -t pointcaster .
-
docker run --rm -it -v ./:/pointcaster:Z -w/pointcaster pointcaster ./scripts/build-linux-release.sh
+
docker build -t pointcaster-linux .
+
docker run --rm -it -v ./:/pointcaster:Z -w /pointcaster pointcaster-linux ./scripts/build-linux-release.sh
```
-
The `docker run` command arguments ensure that the repository is mounted inside the container and set as the working directory.
For a development shell, invoke `bash` or `fish`, where you can configure and build using `cmake`:
-
```
+
```sh
docker run --rm -it -v ./:/pointcaster:Z -w/pointcaster pointcaster bash
The install target places a portable build at `build/linux-release/install/bin/pointcaster`, and the package target creates an AppImage at `build/linux-release/Pointcaster-Linux-<version>.AppImage`, both of which can be run from outside the container.
