Issues installing gnuradio 3.7.9

[marcelrv]

I have some challenges getting this to work
mostly failing with ImportError: No module named _AISTX_swig

To make it work, 2 things were needed:
sudo apt-get install swig
to ensure swig was installed

cmake .. -Wno-dev -DPYTHON_EXECUTABLE:FILEPATH=/usr/bin/python2.7 -DPYTHON_INCLUDE_DIR:PATH=/usr/include/python2.7 -DPYTHON_LIBRARY:FILEPATH=/usr/lib/x86_64-linux-gnu/libpython2.7.so

as in my environment (Ubuntu 18.4 LTS) it kept taking the wrong python version

a second fix needed:

linux; GNU C++ version 7.3.0; Boost_106501; UHD_003.010.003.000-0-unknown

Traceback (most recent call last):
  File "./AiS_TX.py", line 32, in <module>
    from gnuradio.gr import firdes
ImportError: cannot import name firdes

Fix this by replacing the from gnuradio.gr import firdes with from gnuradio.filter import firdes

Thanks @marcelrv for reporting these fixes. I will be happy to approve a pull request, if you provide one ;-)

@marcelrv
I still get the error ImportError: No module named _AISTX_swig even while following your fix.
swig is installed.

What puzzles me is this -- Set runtime path of "/usr/local/lib/python2.7/dist-packages/AISTX/_AISTX_swig.so" to "". Is that correct?

Solved with export LD_LIBRARY_PATH=/usr/local/lib.
