- most files do not contain any license information; if you make
Orocos-derived work (which you do, I think, and which is, of course,
allowed and even stimulated) you are bound by using the same license as the
work you derive from; and in the case of Orocos that is LGPL and not BSD
(most of the time).

This is definitely *not* a derived work. He is using Orocos as a library. The whole point of the LGPL is to allow others to use your library without binding them to your license.

It would be a derived work if he had modified Orocos itself and released it.
