Issue

OpenModelica/OpenModelica#15331

[AnHeuermann]

Some of the packages aren't available on Ubuntu 22.04:

$ sudo apt-get install qt6-base-dev qt6-base-dev-tools qt6-webengine-dev qt6-webengine-dev-tools qt6-l10n-tools qt6-tools-dev qt6-tools-dev-tools qt6-translations-l10n qt6-svg-dev qt6-5compat-dev  qt6-l10n-tools qt6-httpserver-dev qt6-websockets-dev openscenegraph libopengl-dev libqt6openglwidgets6

I guess we can make them optional.

[AnHeuermann]

I want to build a new build-deps:v1.22.3 (new OM GPG key).
Do we also want to include these new build-deps? They should already be part of the Docker image.

[adrpo]

I think they already are. Do you want to build it from scratch or just update the existing one?

[AnHeuermann]

From https://github.com/OpenModelica/build-deps/tree/releases/v1.22 or https://github.com/OpenModelica/build-deps/tree/releases/v1.22-qtwebengine

[AnHeuermann]

The new Ubuntu build-deps:v1.22.3 has all of the Qt5 and Qt6 packages need to build OpenModelica GUI stuff (I hope).

[AnHeuermann]

Maybe we need to split this file into multiple and depending on the OS we need to construct the control / .*spec file.
Maybe something like:

• debian/control.common.in for non-GUI packages
• debian/control.qt5.in for the Qt5 stuff (older OS)
• debian/control.qt6.in for the Qt6 stuff (older OS)

[sjoelund]

Our problem is that we only have 1 for all OSes right now (we only build 1 source package)

[AnHeuermann]

In that case could keep the control file as it is. We can update the README in OpenModelica to point to something like https://github.com/AnHeuermann/build-deps/blob/releases/debian/trixie/nightly/Dockerfile. It lists all package files for Trixie.
For the docker containers we need to to fix them anyway and install additional stuff.

Less convenient as the build-dependencies managed by APT and only applicable for the same architecture as the Docker image.
