Flatpak

For the installation of open_iA under linux we provide a flatpak repository. Please see the user manual or community of your distribution on how to install flatpak itself; to install the open_iA flatpak package, enter:

$ sudo flatpak install https://flatpak.3dct.at/openia.flatpakref

$ designates the shell prompt, do not enter this; additionally, on non-Ubuntu systems, you might have to use another way than sudo to gain administrator privileges, please again, refer to the user manual or community of your distribution!

Note: The flatpak package does not include:

• the AI and ASTRA modules (requires CUDA; as far as we know there is no way to address CUDA devices from flatpak yet)
• the DreamCaster module (requires OpenCL; not supported yet from within flatpak as far as we are aware)
• the VR module (since we didn't have a chance to test yet whether OpenVR hardware can be accessed from within the flatpak sandbox)

If you need to run any of these modules on Linux, you will need to build a version for your distribution. Please use our superbuild, which is able to build these modules, or refer to our Build instructions!

Flatpak is our compromise solution, as it is basically impossible to build a generic executable for any linux distribution without it; nor is it feasible with our time budget to build a separate binary release package for all linux distributions currently in use out there.

Known Issues:

• Due to currently unknown reasons, sometimes an error 503 happens when the flatpak installer is pulling the required data from our servers. The simple workaround is to re-run the install command, it will resume downloading where the previous run was aborted!

Should you encounter any other issues, please submit an issue!
