Re: [Discuss-gnuradio] gr-tutorial/examples/tutorial4 Python module missing

[Peter Mathys]

I did actually find a tutorial.py file in /gr-tutorial/python (I 
expected it to be there yesterday, but must have overlooked it) and 
copied it to /usr/local/lib/python2.7/dist-packages. Now the error 
message that I get is

ImportError: No module named _tutorial_swig

If I search for _tutorial_swig in /gr-tutorial I find the following:

address@hidden:~/gnuradio/gr-tutorial$ find -name '_tutorial_swig*'
./build/swig/CMakeFiles/_tutorial_swig.dir
./build/swig/CMakeFiles/_tutorial_swig_swig_tag.dir
./build/swig/CMakeFiles/_tutorial_swig_swig_tag.dir/_tutorial_swig_swig_tag.cpp.o
./build/swig/CMakeFiles/_tutorial_swig_doc_tag.dir
./build/swig/CMakeFiles/_tutorial_swig_doc_tag.dir/_tutorial_swig_doc_tag.cpp.o
./build/swig/_tutorial_swig.so
./build/swig/_tutorial_swig_swig_tag
./build/swig/_tutorial_swig_doc_tag.cpp.in
./build/swig/_tutorial_swig_swig_tag.cpp.in
./build/swig/_tutorial_swig_swig_tag.cpp
./build/swig/_tutorial_swig_doc_tag.cpp
./build/swig/_tutorial_swig_doc_tag

Do I need to copy any of these to the PYTHONPATH directory?
