Hi,

I'm getting the following when I launch bluetoothd with -n -d:

..
Can't load plugin /usr/lib/bluetooth/plugins/netlink.so:
/usr/lib/bluetooth/plugins/netlink.so: undefined symbol: debug
..

AFAIK, those libtool plugins are allowed to have undefined symbols after
linking as they will probably be resolved during runtime loading but the
warning above wasn't present on previous versions like 4.41 for example.

# ldd -u -r /usr/lib/bluetooth/plugins/netlink.so
     26771:     /usr/lib/bluetooth/plugins/netlink.so: error: symbol

Unused direct dependencies:


So we have 3 undefined symbol from glib and 2 internal symbols from
logging.c: debug() and info(). There's no difference if I install the
libtool la file or not. Since glib is already needed by bluez daemon,
those undefined symbols seems harmless but AFAIK the internal ones
should have been linked against the static logging.o.

Or do I miss something?


Thanks,
