Building
GNOME Builder
GNOME Builder is the environment used for developing this application. It can use Flatpak manifests to create a consistent building and running environment cross-distro. Thus, it is highly recommended you use it.
- Download GNOME Builder.
- In Builder, click the "Clone Repository" button at the bottom, using
git@gitlab.gnome.org/Incubator/loupe.gitorhttps://gitlab.gnome.org/Incubator/loupe.gitas the URL. - Click the build button at the top once the project is loaded.
Installation
Depending on how you want it installed instructions can differ. If you used GNOME Builder to build it, clicking the bar at the top window will open a submenu with "Export Bundle". This will create a flatpak bundle, which can be installed on any system that supports flatpak.
In order for the Loupe flatpak to be able to read the directory images are installed in, you must install a bundle. Once you have a bundle installed, development builds will work properly.
