Distributing programs programmed in QB64?

[DSMan195276]

LGPL is a software license, and basically it says that if code licensed under it is included in your executable then you have to release the source code for the entire thing. So whether you put in an include or etc. doesn't matter, that's still part of the source and would have to be released.

I'm regards to your other question, the requirement ends at system libraries like the windows API. LGPL is also less strict than the GPL and doesn't impose the requirement if the dependency is a dll.
