[Bluez-devel] Bluez-utils-3.30 plugins failing at startup

[Bluez-devel] Bluez-utils-3.30 plugins failing at startup

I have been working to get a simple connection working between BlueZ and a CSR Bluetooth module.  I have again hit a roadblock in 
that when initializing the libxxxxx.so plugins, the call to g_module_open fails as shown in the following:

Apr 26 16:27:28 freqonec001 hcid[2817]: Can't load plugin: /usr/lib/bluetooth/plugins/libnetwork.so: invalid mode for dlopen(): 
Invalid argument
Apr 26 16:27:28 freqonec001 hcid[2817]: Can't load plugin: /usr/lib/bluetooth/plugins/libserial.so: invalid mode for dlopen(): 
Invalid argument
Apr 26 16:27:28 freqonec001 hcid[2817]: Can't load plugin: /usr/lib/bluetooth/plugins/libinput.so: invalid mode for dlopen(): 
Invalid argument
Apr 26 16:27:28 freqonec001 hcid[2817]: Can't load plugin: /usr/lib/bluetooth/plugins/libaudio.so: invalid mode for dlopen(): 
Invalid argument

It appears that the dlopen() is failing when called within g_module_open, which is called from /utils/hcid/plugin.c

In my configure, after specifying all of the various directories, I select --enable-debug and --enable-all; I get no errors in the 
make and make install.  The .so and .la files are all in the /usr/lib/bluetooth/plugins directory.  What am I missing?

Interestingly, and probably because I have modified the audio.conf file, the audio service DOES register itself, despite the failure 
of the libaudio.so plugin, as shown in the following...

Apr 26 16:27:28 freqonec001 hcid[2817]: Registering service object: ident=audio, name=Audio service (/org/bluez/service_audio)

When I try to Activate the audio service, it falls over, because under 3.30, the service apparently is looking for a plugin, and not 
the daemon that was used in 3.29 and before (I think I have this right).

Apr 26 16:34:48 freqonec001 hcid[2817]: /org/bluez: org.bluez.Manager.ActivateService()
Apr 26 16:34:48 freqonec001 hcid[2817]: Unable to execute /usr/lib/bluetooth/bluetoothd-service-audio

Prior to today, to get SOMETHING [sort-of] working, I copied a 3.29 version of bluetoothd-service-audio into the /usr/lib/bluetooth 
directory and it had some functionality.  However, once I renamed that module to take it out of the equation, ActivateService fails: 
Exec format error.

The entire startup log (this time around) is attached.
