ImportError: No module named dvbt_swig

[VigibotDev]

Hello,
I can't deal with this issue:( don't understand python "swig", I tested swig and swig3.0 from debian repo with same issue.

linux; GNU C++ version 4.9.1; Boost_105500; UHD_003.007.003-0-unknown

Traceback (most recent call last):
  File "/root/gr-dvbt/apps/top_block.py", line 23, in <module>
    import dvbt
  File "/usr/lib/python2.7/dist-packages/dvbt/__init__.py", line 45, in <module>
    from dvbt_swig import *
ImportError: No module named dvbt_swig

>>> Done

Yo @serveurperso. This happened to me too - if you've installed swig you just need to re-compile the whole application and it should work. It's probably an issue that compilation succeeds without errors if you don't have swig installed, when in fact it makes the python libs unusable... :)

Thank @stackprogramer 👍
It works like a charm:
First, IF you run cmake without SWIG installed, there are warnings:
-- Checking for module SWIG
-- Disabling SWIG because version check failed.
after installing SWIG as @stackprogramer mentioned, it should be showing as:
-- Checking for module SWIG
-- Found SWIG version 3.0.12.
-- Found SWIG: /usr/bin/swig3.0

And my codes working just fine!
