TUM-UI

GTK4 Based UI for TUM related canteen and MVG information. Intended to be run on a Raspberry PI as an office status display.

Examples

Building

Requirements

Fedora

sudo dnf install gtkmm4.0-devel libadwaita-devel libcurl-devel g++ clang cmake git
sudo dnf install libsoup3-devel sqlite-devel ninja-build

Building

git clone https://github.com/COM8/tum-ui.git
cd tum-ui
mkdir build
cd build
cmake ..
cmake --build .

Flatpak

The TUM-UI can be built and installed using Flatpak.

Requirements

Fedora

sudo dnf install flatpak flatpak-builder
flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
flatpak install flathub org.gnome.Sdk/43 org.gnome.Platform/43

Debian/Ubuntu

sudo apt install flatpak flatpak-builder
flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
flatpak install flathub org.gnome.Sdk/43 org.gnome.Platform/43

Building

Add --jobs=1 to the flatpak-builder command when building on a Raspberry Pi to prevent running out of RAM.

git clone https://github.com/COM8/tum-ui.git
cd tum-ui
flatpak-builder --force-clean flatpak_build_dir de.tum_ui.cli.yml

Installing

flatpak-builder --user --install --force-clean flatpak_build_dir de.tum_ui.cli.yml

Cross-Compiling

In case you would like to cross-compile for the Raspberry Pi (aarch64), this can be done as follows:

sudo dnf install qemu-system-arm qemu-user-static
sudo systemctl restart systemd-binfmt.service

flatpak install flathub org.gnome.Sdk/aarch64/42 org.gnome.Platform/aarch64/42
flatpak-builder --arch=aarch64 --repo=repo --force-clean flatpak_build_dir de.tum_ui.cli.yml
flatpak build-bundle --arch=aarch64 ./repo/ de.tum_ui.cli.flatpak de.tum_ui.cli

# Copy the "repo" dir to the target system
flatpak --user remote-add --no-gpg-verify tum-ui-repo repo
flatpak --user install tum-ui-repo de.tum_ui.cli

Uninstalling

flatpak uninstall de.tum_ui.cli

Executing

flatpak run de.tum_ui.cli

Autostart

To enable autostart once the PI starts, a systemd service is available.

nano /etc/systemd/system/tum_ui.service
# Fill with the content of the tum_ui.service file located in this repository

systemctl enable tum_ui.service

Once done, restart the PI, and the application will start automatically. The config file is located in /root/tum_ui_settings.json once the application started for the first time.
