This repository holds recipes and patches to build the Beremiz packages and installers for Beremiz website.
Patches have same license as projects being patched. For other files, unless made explicit in file header, GPLv3 applies.
Beremiz development uses Mercurial, but git repositories that are kept in sync.
Build from both Mercurial and Git repositories is supported.
Use code from https://github.com/beremiz repositories.
Workflows described in .github/workflows are meant to run on a GitHub runner. Please refer to GitHub documentation to run workflows on your own fork.
Dockerfile and part of Makefiles are used for windows installer build, but for Snap build, only snapcraft.yaml is used.
Use code from your local Mercurial repositories, cloned from https://hg.beremiz.org
Uses Makefiles and Dockerfile to build windows installer and Makefile+snapcraft.yaml for Snap package.
Hereafter is documented how to use Makefile and Docker in case of Manual Build
A usable Docker is required. Docker is used to ensure a reproducible build environment.
Other containerization/virtualization could be used to achieve the same effect.
Reference build environment is obtained by applying provision_focal64.sh on Ubuntu 20.04 amd64.
The top Makefile expects source code of Beremiz, Matiec and CanFestival to be sibling to beremiz_public_dist directory, in the 'source directory'. For example :
~/src
/beremiz
/beremiz_public_dist
/matiec
/canfestival [optional]
/Modbus [optional]
/open62541 [optional]
Repositories can be cloned from https://hg.beremiz.org .
Intermediate and final results are all placed in a single 'build directory' during build process.
The script rebuild_docker.sh is used for that purpose.
Synopsis:
./rebuild_docker.sh [build directory]
Source and Build Volumes :
| Role | Docker Volume | Host path in example | Rationale |
|---|---|---|---|
| source directory | /home/runner/src | ~/src | Always relative to CWD : "../" |
| build directory | /home/runner/build | ~/build | First argument to rebuild_docker.sh or ~/build |
'build directory' can be specified as absolute path argument of rebuild_docker.sh. If not specified it defaults to ~/build
#!sh
./rebuild_docker.sh ~/build_next
Note: 'build directory' is created if not already existing.
The script build_in_docker.sh is used for that purpose.
#!sh
./build_in_docker.sh
Note: 'build directory' must exist before calling build_in_docker.sh, otherwise Docker will create it as root user. Be sure to create it again if you delete it.
Resulting installer is Beremiz-${timestamp}.exe in 'build directory'.
Once Docker image ready, the scripts enter_docker.sh and enter_docker_as_root.sh let you issue build commands, or install additional packages.
clean_docker_container.sh and create_docker_container.sh and clean_docker_image.sh and build_docker_image.sh are invoked by rebuild_docker.sh.
snapcraft.yaml does not rely on HG or GIT repos, but refers to local sources, this is responsibility of caller to prepare sources for snapcraft.
Reasons for this are :
- no parameters or conditional variables exist to tell snapcraft.yaml where to get the source from
- building from local source should be always possible
- revisions.txt must be updated in any case so that it is always possible to know what version was used to build resulting package
- when Snap is built from GitHub actions, Makefile isn't used at all, and GitHub action workflow organize sources and revisions.txt on its own.
In the end, instead of just calling snapcraft to get a snap package, it is more complicated:
# assuming source repositories are cloned in ~/src
# and build happens in ~/build
cd ~/build
make -f ~/src/beremiz_public_dist/Makefile DIST=snap
Resulting snap package is sources/beremiz_${version}_${platform}.snap. It can be installed this way:
sudo snap install sources/beremiz_1.4-beta2_amd64.snap --dangerous --devmode
