Gtranslator (-the GNOME translation making program-) If you get this code from the git repository the easier way to build is using gnome-builder. There's a flatpak manifest that gnome-builder uses to build all deps and launch the application sandboxed so you don't need to worry about dependencies. If you want to build by hand, you should follow the meson build commands: meson _build ninja -C _build ninja -C _build install
