Here is a direct quote from the Xojo™ Home page
"This means it is cross-platform, so you can build for any platform from any platform"
This however is a blantantly untrue statement.
Xojo supports SIX(6) Platforms, meaning there are 36 combinations
But as the below table show, only 13 of those 36 are true.
As a matter of fact, you cannot even DEVELOP on 3 of them!
		Development Platform
	Destination	macOS	Windows	Linux	iOS	Pi	Web
	macOS	Yes	32bit	No	No	No	No
	Windows	Yes	Yes	No	No	No	No
	Linux	Yes	Yes	Yes	No	No	No
	iOS	Yes	No	No	No	No	No
	Pi	Yes	Yes	Yes	No	No	No
	Web	Yes	Yes	Yes	No	No	No
So please don't be fooled by their "marketing materials"
Do your own due dilegence and find out for yourself
