API Changes in Bluez 4.x Break Bluecove-GPL

[Michael Chang]

I'm getting the following error when using bluecove 2.0.3 with Ubuntu
Linux 8.10. This version of Ubuntu ships with the 4.x series of Bluez,
which is known to contain API breakage.

Native Library bluecove not available

Yes Bluez 4 have only D-Bbus API. For this we created bluecove-bluez.....

Hmm... it appears that they've also modified the dbus API in this version. Are there any new patches to bluecove-bluez for these changes to the latest version that are not in git?

No, there are no patches.
The new classes should be created base on new API!

Any help is appreciated.
