Installation
Ready-made packages are released in our GitHub repository release page and in the build workflow. They need no compiler, Alire or MSYS2.
Every package has the program, the carbon intensities of the countries, the README and the licences.
Linux
For x86_64 and aarch64:
Debian, Ubuntu:
sudo apt install ./joularenergymeter_<version>-1_amd64.deb
Fedora:
sudo dnf install ./joularenergymeter-<version>-1.x86_64.rpm
Arch Linux:
sudo pacman -U joularenergymeter-<version>-1-x86_64.pkg.tar.zst
These packages also install SDL2.
The AppImage has SDL2 inside and runs on any distribution: make it executable with chmod +x, then start it.
The tar.gz needs the SDL2 package (libsdl2-2.0-0 on Debian and Ubuntu, SDL2 on Fedora).
All of them need glibc 2.35 or newer (Debian 12, Ubuntu 22.04, Fedora 36 and later), as they are built on Ubuntu 22.04. On Raspberry Pi, this means a 64 bits OS.
macOS
Open the .dmg and drag the application to Applications.
It is one application for Apple Silicon and Intel Macs, with SDL2 inside, and needs macOS 15 or newer (GNAT’s Ada runtime is built for 15).
The application is only signed ad hoc, so macOS blocks it the first time: open System Settings > Privacy & Security and click Open Anyway.
Started from Finder, it writes its CSV files to the home folder. To read the power, it needs root (see Required privileges).
Windows
Run the .msi (it installs to Program Files, adds a Start menu shortcut, and is removed from Settings > Apps), or unzip the .zip and run joularenergymeter.exe.
Both ship SDL’s own SDL2.dll.
The installer is not signed, so SmartScreen asks once (More info, then Run anyway).
FreeBSD
sudo pkg install sdl2
sudo pkg add joularenergymeter-<version>-freebsd14-amd64.pkg
pkg add looks for dependencies only beside the file, hence SDL2 first.
A tar.gz is also available.
The package is made for the FreeBSD version it was built on.
