[Bluez-users] symbol lookup error

[Bluez-users] symbol lookup error

Hi,

I compiled blueZ libs and utils without a problem. (using ./configure for
libs and ./configure --enable-test for utils)
After this, I ran hciconfig hci0 up, then hciconfig, both ran fine:
hci0: Type: USB
BD Address: 00:11:67:0F:C0:E7 ACL MTU: 678:8 SCO MTU: 48:10
UP RUNNING PSCAN ISCAN
RX bytes:77 acl:0 sco:0 events:9 errors:0
TX bytes:34 acl:0 sco:0 commands:9 errors:0

However, when I try to run hcitool -i hci0 inq:

Inquiring ...

00:0D:93:16:49:33 clock offset: 0x38ca class: 0x102104
hcitool: symbol lookup error: hcitool: undefined symbol: bt_free

I get this symbol lookup error. Then when I try hcitool -i hci0 scan:

Scanning ...
hcitool: symbol lookup error: hcitool: undefined symbol:
hci_read_remote_name_with_clock_offset

Yet another lookup error.

Dump for the inq:

Dump for the scan (very similar, i guess scan uses inquiry as well)

Would anyone know what might be wrong? Thanks.

this is a library mismatch. Make sure that you delete the old Bluetooth
libraries (maybe plural) on your system and make a clean re-install.

Marcel
