I tried to cross compile my project on Windows 10 for the Ubuntu executable file.
I used the packaging tool in my UE5 to do this.

However, when I moved the packaged project to Ubuntu for execution, I got the following error：

I *think that with Linux it’s not so simple. It may be in regards to a missing .dll. I don’t think you can package for Linux straight out of the box as it requires some setup and additional stuff. There is some documentation on this somewhere on epics site. Tried it myself and didn’t have the time to work through it. I know that doesn’t help much, but I don’t think it’ll work out right without jumping through the hoops to set it up correctly.
