Yes, and all symbols have a different version name in 1.0.2 and 1.1.0. (What is actually the important thing.) > Is this situation > supported or should we expect things to break?

As far as I know, it should only break when they use dlopen(). They most likely won't be using dlvsym() in that case and then it can pick any version. It could of course also break if they do very weird things. But I guess we'll have to see if something breaks or not. Kurt
