Bluecove is a java library and is platform-independent. It uses bluez in linux.
But the instalation of bluez on ubuntu doesn't provide a versionless
symlink that is necessary for bluecove to work without user
intervention. Bluecove links against a versionless library to be able
to use the same build with bluez version 3 and version 4.
I thought not having a versionless symlink was a bug, but it seems to
be an explicit decision, if that is the case, then java apps using
bluetooth will always need the user to install libbluetooth-dev
instead of being able to work with the latest version. Since backwards
compatibility should be a given, I don't see why there coudn't be a
