Re: gr-display "import display" causes error

[Marcus Müller]

Hi Jim,

sounds like you have a local installation of gr-display (in /usr/local) and the python 
part can't find the underlying compiled C++ library. Can you check where 
"libgnuradio-display…" has been installed to (since you probably compiled this yourself, 
there might be a `install_manifest.txt` in your build folder). That directory (something 
like /usr/local/lib64 maybe?) needs to be in the LD_LIBRARY_PATH environment variable for 
the automatic Linux library finder to be able to find it :)

Best regards,
Marcus
