Re: [Bluez-devel] Dealing with the bluez-utils dependencies

[Claudio Takahasi <cktakahasi@gmail.com>]

Hi Marcel,

Regarding D-Bus support for pand and hcid.=20
DBUS is under development and there is backward compatibility problem.
Some APIs changed, I suggest check the dbus version at build time=20
and fix the code to support this. The latest version(0.33) is not compatibl=
e
with 0.23.


Regards,
Claudio
