Re: [Discuss-gnuradio] Trouble getting GNUradio/UHD working (with PyBombs)

[David Donley]

Pybombs usually installs stuff in ~/target and adds a script there called 
~/target/setup_env.sh which sets up paths. You should try running that before 
building gnuradio things after installing pybombs. If the includes still aren't 
found try looking in ~/pybombs or ~/target for them. You should not have needed 
the apt-get lines after successfully installing pybombs and should probably 
uninstall those items.
