I’ll ask the obvious: what’s the problem with running FileMaker on Ubuntu in WINE?
Saw this link that shows WINE seemed to support FileMaker at some point:
https://appdb.winehq.org/objectManager.php?sClass=application&iId=337
I have had bad luck with WINE, and the comments I have read are that it is too buggy for File Maker to trust.
Trying to get WINE to run, and even configure it to open files, can be a problem depending on the universe of distros. Would not install right on Kubuntu, or work with PCLinuxOS for me.
