Ok, so you think this is probably because I use the last version of bluez that I get this compile error. But as you can see I have the two versions installed, so it should works correctly. The old bluez version installed on my distro was 3.36 $ apt-cache show libbluetooth-dev | grep Version Version: 3.36-1 The new bluez version installed on my distro is 4.94. The 2 libraries version are 2.11.2 and 3.11.2 : $ ls -l /usr/lib/libbluetooth.* -rwxr-xr-x 1 root root 938 2011-06-12 01:39 /usr/lib/libbluetooth.la lrwxrwxrwx 1 root root 22 2011-06-12 17:02 /usr/lib/libbluetooth.so -> libbluetooth.so.3.11.2 lrwxrwxrwx 1 root root 22 2010-12-18 15:25 /usr/lib/libbluetooth.so.2 -> libbluetooth.so.2.11.2 -rw-r--r-- 1 root root 78900 2008-07-12 11:20 /usr/lib/libbluetooth.so.2.11.2 lrwxrwxrwx 1 root root 22 2011-06-12 17:02 /usr/lib/libbluetooth.so.3 -> libbluetooth.so.3.11.2 -rwxr-xr-x 1 root root 104024 2011-06-12 01:39 /usr/lib/libbluetooth.so.3.11.2 If I compile like this plugz, I get the error. If I change the /usr/lib/libbluetooth.so to target the old libbluetooth.so.2.11.2, I get the same error. Some people use this headset on Linux[8][9]. So, I think the headset should be supported using bluez... I read documentation[1][2][3][4][5][6][7][8][9] but I can't bind my headset and my computer using bluetooth... Can you help me?
