Yeah, I'm pretty sure this won't work for trolltech. Even if the code was
originally gpl, I can release my own code to myself with a different
license and use that with the commercial Qt (but that's just my opinion; I
hadn't seen their FAQ before this).
Anyway, the reason why I used GPL was because it seemed like the simplest
way to do it.. I did use the GPL version of qt, and lua_qt itself would be
a derivative of that, but most of the code on the final library is
actually generated by tolua, it doesn't come with the package, so I don't
There's another situation too: can you make a commercial lua program, and
distribute as one big .luac file along with the lua_qt dlls and the lua
interpreter (and the source for qt and lua_qt)? Sure, 'entry number 187'
says you can distribute the program as BSD (which would be a clear
violation of the GPL), but in this case the program is clearly separated
from qt, and the lua code is basically closed-source (how much can you get
from a compiled lua chunk?). Does your lua script become GPL when you
loadlib() a GPLd library? (I bet trolltech would say yes :)

I guess so..
