Im running Xojo 2018 r3 on an iMac with MacOS 10.14.1. I also can run Ubuntu Linux 14.04 Desktop under Parallels.
I found one of my applications built for Linux x86 64-bit with the current Xojo version would not run on my Linux when the application was double-clicked. Others of my 64-bit Linux applications built with previous versions of Xojo ran with no problems. So I created a Hello World! project for 64-bit Linux and found it also would not run.
Is this a problem specific to my Ubuntu 14.04 and my current version of Xojo or does it happen with other 64-bit versions of Linux?
