The README appimage file describes the CLI method to install Cinelerra-GG 1) download AppImage file move from Download folder to your preference 2) make it executable chmod u+x {AppImageFile name} 3) run it ./cinelerraGG.AppImpage -------------------------------- Now I have also tried the /GUI method/ to download, Run And Integrate Cinelerra AppImage with installed *AppImageLauncher*. On openSUSE Leap 15.3 (and surely similar on other distros) AppImageLauncher is integrated with Firefox as follows: 1) start download the AppImage file, and a widget popup in Firefox with the option to open it with AppImageLauncher (instead of Saving it) 2) At the end of the download a new popup asks to integrate it with your desktop system. OK -------------------------------- (The AppImage installation directory is /home/user/Application by default, but can be customized in the Launcher widget) That's it. Both *Cin* and *Cin-multi* were installed this way, automatic integrated with icons and in the app-menue in Gnome, see the attached screenshot AppImage.png and urls to articles for detailed info below. I have used *alacarte* to add the icon comment sub-text to *Cin-multi* for multiple bit version.the icon, as also mentioned in a previous post AppImage and Desktop Integration with an app launcher https://www.mail-archive.com/[email protected]/msg02692.html Packages I installed first on Leap 15.3 zypper se -is appimage Loading repository data...
