Python3 build - undefined symbol

[Jorge Rivera Gutiérrez]

Hello,

I've been trying to build python-openzwave with the intention of using it with Home Assistant (https://home-assistant.io/). 

I'm trying to run it temporarily on my PC (Ubuntu 16.04). 

I have a Z-Wave Bridge Controller from Sigma (UZB2-U-BRG) and I have successfully detected nodes uisng MinOZW. 

Home Assistant is a python3 app, so they give instructions to build the wrapper using python3 (https://home-assistant.io/getting-started/z-wave/). 

I tried following their instructions. The build process went smoothly, except for some warnings. 

Here are my versions:

$ python3

Python 3.5.2 (default, Nov 17 2016, 17:05:23) 

$ dpkg -l cython3

...

ii  cython3                            0.23.4-0ubuntu5        amd64                  C-Extensions for Python 3

However, when I try to run the program it fails loading the z-wave component. I tracked it down to the import of libopenzwave. 

I tried to import it manually and here's the error I get:

jrivera@bohr:~/work/python-openzwave-0.3.1/build/lib.linux-x86_64-3.5$ python3

Python 3.5.2 (default, Nov 17 2016, 17:05:23) 

[GCC 5.4.0 20160609] on linux

Type "help", "copyright", "credits" or "license" for more information.

>>> import libopenzwave

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

ImportError: /home/jrivera/work/python-openzwave-0.3.1/build/lib.linux-x86_64-3.5/libopenzwave.cpython-35m-x86_64-linux-gnu.so: undefined symbol: _ZN9OpenZWave7Manager16GetNodeProductIdB5cxx11Ejh

>>> 

This is my try from the 0.3.1 archive. I tried from the python3 branch and same happens. Notice that it is trying to load the lib from the local dir, so it is using my fresh build :)

Any suggestions?

Thanks,
