Linux

The AppImage is self-contained (needs glibc 2.39 or newer: Ubuntu 24.04, Fedora 40, Debian 13, Arch): make it executable with chmod +x and run it. The tar.gz uses your system libraries, so Qt 6 and the usual libraries must be installed.

Windows

Windows packages are in-place zip files: extract and run eglantine.exe, or eden-cli.exe from a terminal.

macOS

The PGO builds are the same programs compiled with profile-guided optimization (clang plus Eglantine's profile); prefer them when your CPU supports it.
