Python module - Ubuntu 12.04 64bit

[chris@xxxxxxxxxx (Chris Maciejewski)]

Hi,

I am trying to build Python module following instructions here:

http://trac.pjsip.org/repos/wiki/Python_SIP/Build_Install

On Ubuntu 12.04 32bit it works just fine, however on 64bit version I
am getting error as below:

$ python
Python 2.7.3 (default, Aug  1 2012, 05:14:39)
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pjsua
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/pjsua.py", line 59, in <module>
    import _pjsua
ImportError: /usr/local/lib/python2.7/dist-packages/_pjsua.so:
undefined symbol: pjsua_start

Perhaps need to change build target to x64 somewhere?

Any suggestions how to fix this very much appreciated,

Regards,
Chris
