[Gambas-user] how to detect compilation runtime componets available?

[Brian G]

Piccoro, 

Can you post an example app to show what you are trying to do? 
I find this whole conversation confusing.. kind of anyway. 
What are you working on, Library or Component? 

the app is usually created as a cmdline app or a graphical interface so you know at runtime.
