Description:Asterisk runs normally unless chan_mobile module is loaded. On load, the following error message is shown:

asterisk: symbol lookup error: /usr/lib/asterisk/modules/chan_mobile.so: undefined symbol: hci_get_route

Asterisk immediately stops and returns me to a command line.

Build of asterisk and chan_mobile was clean, no errors reported.

I have bluez libs (3.26-2.1) and utils (3.24-2.1) installed and apparently functional. (Able to scan, connect, etc. to phones.)

This is on asterisk-addons trunk, r531.

****** STEPS TO REPRODUCE ******

Added chan_mobile.so to noload in modules.conf.
Started asterisk, confirmed normal functionality with test call.
loaded chan_mobile module

What is the output of an ldd on chan_mobile.so?

I've attached the LDD output as a file - quite a few undefined references; apparently I am missing a prerequisite? I though I had that covered between the libs and utils packages.

That is ld output, not ldd.

My mistake! ldd says:

# ldd /usr/lib/asterisk/modules/chan_mobile.so
       linux-gate.so.1 =>  (0xffffe000)
       libc.so.6 => /lib/libc.so.6 (0xb7e56000)
       /lib/ld-linux.so.2 (0x80000000

I had the same problem - the Makefile doesn't seem to link the module with the Bluetooth library.

This probably isn't the absolute correct way to do this, but will get you through the compile:

add the following to the end of asterisk-addons-trunk/channels/Makefile:

chan_mobile.so:        LIBS+=-lbluetooth

Hope that helps.

The way it is supposed to work is that menuselect sees the dependency on bluetooth and automatically links chan_mobile against it, which it does on my system for example. I'm curious - what this a fresh checkout? If not can you perform a fresh checkout and try? What is the output of configure?

I see the problem - it looks like one of the unofficial patches that allows chan_mobile to work on 1.4 removes the link dependency on bluetooth (as you indicated).

The part of the patch that removes the:


from the MODULEINFO part of chan_mobile.c should NOT have been done.

That fixed it...should have seen it earlier.

In light of gkloepfer's comment about "unofficial patches", I am going to close this issue.  If you are not using any patches, please feel free to reopen this issue, so we can look at it further.
