Build and packaging system based on Docker

The developer-mode Dockerfile is a monolithic source based build. All of the packages are compiled from source on top of a minimal OS image based on Debian-slim. You need to provide a working Docker container on your platform. The Docker image and container will manage all of the platform packages and build tools needed for a source build. By using Docker you can easily develop on Linux or OS X.

This build system is intended to be used with a CI system. You can edit changes directly on github.com. Then, TravisCI.org can build the system as part of the process of a pull request. If for example you need to make a small version change to a package, the CI build system will automatically check the build.

A Docker image named tcl-2020-dev is created for the system platform is created. This image can be created with

cd developer-mode && docker build -t tcl-2020-dev .

This Docker image has all the required platform packages. The platform packages are installed in the script developer-mode/setup-docker-env.sh.

Source packages are added to the Docker image using the developer-mode/builds/build-all.sh script.

To add packages or features create a new shell script in developer-mode/builds. Add your new build script to developer-mode/builds/build-all.sh

See the .travis.yml file for the build actions.

The builds can be run using this one line Docker run command

mkdir work
docker run -it -v $PWD/work:/work --name dev tcl-2020-dev sh /builds/build-all.sh

In Docker we mount the directory /work for the source code. You can git clone or copy source files there. If the source directory is present, /work/tcl, then the /builds/build-tcl.sh will skip the git clone and use the provided source.

The tcl-2020-dev container can be run in the background using.

docker run -d -v $PWD/work:/work --name dev tcl-2020-dev

Then you can enter the docker container instance with docker exec -it dev /bin/bash.
