Or, is there an intended way for non-GPL programs to interface with BlueZ? As for the non-GPL use of the kernel, I was referring to: (from http://www.kernel.org/pub/linux/kernel/COPYING) "NOTE! This copyright does *not* cover user programs that use kernel services by normal system calls - this is merely considered normal use of the kernel, and does *not* fall under the heading of "derived work". Also note that the GPL below is copyrighted by the Free Software Foundation, but the instance of code that it refers to (the linux kernel) is copyrighted by me and others who actually wrote it." But I'm not sure if by "disagree" you meant disagree with the interpretation, or the intent behind it... I have been advised by our lawyers that this does allow simple use of *.h files to include kernel constants and things like that -- but would not extend to user-land libraries.

My understanding is that it > is OK to use the linux kernel syscall interface from non-GPL code, but > that this would not extend to libbluetooth.so... Actually I disagree with the non-GPL use of the syscall interface, but I am not lawyer. From my understanding all the bluetooth/*.h include files are GPL and you need them for your application. You can't replace them without ending up in derived work. Regards Marcel ------------------------------------------------------- This SF.Net email is sponsored by Yahoo. Introducing Yahoo!
