I wish that build-gnuradio script worked for Debian 8.  I spent the whole evening yesterday installing gnuradio and op25 on a raspberry pi.  Looked like everything was good, till I fired up the scope tool:

./scope.py --args rtl=0 -f 772.63125 -g 65 -o 17 -N LNA:35 -V -v -S 250000 -q 51
attempts to launch, but dies
Something about "recreating status bar in wxFrame " . which is some sort of wxWidgets error.

Thanks, flkmrz! I recently posted something similar on my blog
(https://blog.febo.com) and I'm going to edit those posts based on some
of what you've said below.

I strongly prefer using the "build-gnuradio" script
(http://sbrac.org/files/build-gnuradio) to build the system from
sources. It requires very little user intervention, makes sure you have
all the required .deb or .rpm packages installed, and gives you the
latest version of the code base. But as of right now (28 June 2017) the
rtlsdr components don't build properly due to upstream code changes. I
have a good feeling that it will be fixed very soon, but over the last
week I've been tearing my hair out.
