Re: [Discuss-gnuradio] UHD won't work with GRC

[Scott Johnston]

Thanks Josh. Getting the newest gnuradio from git solved the uhd 
problem, but now gnuradio is broken. I know it must be some path problem 
but I have tried the usual tricks: I set my 
PYTHONPATH=/usr/local/lib/pkgconfig/dist-packages and 
LD_LIBRARY_PATH=/usr/local/lib and I did sudo ldconfig in the gnuradio 
directory. And I checked /etc/ld.so.conf and /usr/local/lib is in there.

I get the following problem when trying to run any gnuradio programs. 
And when I try gnuradio-companion a gui pops up that says "can't import 
gnuradio, are your PYTHONPATH and LD_LIBRARY_PATH set correctly?
