docker.io/cgal/bundle-3d-demo

Automatic building of the CGAL 3D demo (Polyhedron Demo)

Overview

A simple command line to build the demo from $HOME/Git/cgal, and put it in the results/ sub-directory of your current working-directory:

docker run --rm -v $PWD/results:/results:Z -v ~/Git/cgal:/cgal:ro docker.io/cgal/bundle-3d-demo  `/scripts/build.sh -j6 && /scripts/deploy.sh'

Usage

Container Directories

The container scripts uses those directories:

• /cgal/ is the location of CGAL sources. It can be either a Git checkout of a CGAL branch, or an extracted tarball.
• /build/ is the binary directory used during the compilation. In particular /build/demo/Polyhedron/ will be the binary tree of the demo.
• /scripts/ contains the two scripts used to build and create the AppImage of the demo:
  • /scripts/build.sh
  • /scripts/deploy.sh
• /dist/ is the AppDir created by linuxdeployqt before appimagetool is called.
• /results/ is the output directory where the AppImage binary will be created.

Directories you should mount as Docker volumes:

• /cgal/, as a read-only volume, because that is the input of the scripts, and
• /results/, as a read-write volume, to get an easy access to the result.

Directories that can be mounted as Docker volumes for debugging purpose:

• /build/ (read-write) if you want to avoid rebuilding the full demo between two runs of the container,
• /scripts/ (read-only) if you want to debug the scripts,
• /dist/ if you want to debug issues with linuxdeployqt.

The Main Command

The entrypoint of the container is ["scl", "enable", "devtoolset-4"]. That command only accept one extra option, that is interpreted by a shell. Quote it with single-quotes (').

For example, a possible debugging command line is:

docker run --rm -t -i -v $PWD/build:/build:Z -v $PWD/results:/results:Z -v $PWD/scripts:/scripts:ro -v $PWD/dist:/dist:Z -v ~/Git/cgal:/cgal:ro docker.io/cgal/bundle-3d-demo  'bash -x /scripts/build.sh -j6 VERBOSE=1 && bash -x /scripts/deploy.sh'

The extra :Z option to volume specification is used on Linux version where docker-selinux is enabled. It allows the container to write to the directory.
