I don’t think cross compilation works with external plugins. Install Ubuntu on a USB hard disk or similar and compile it there. You may also need a script to compile the plugin there. I can then find you mine. But it is not always necessary. If you have no experience with Linux, be prepared that it may take a few hours until everything works. Linux is “special”.
Thank you! So this plugin is supported to run under Linux (Ubuntu 20.04 to be exact), right？ But I need to compile the plugin separately in Linux, and I can’t simply cross compile the whole project.
I might need to spend a little more time on this “special” system.
