Dear Helper,
I had installed GNU Radio, but when I run gnuradio-companion in
Ubuntu Terminal, I received the following message:
*Cannot import gnuradio.*
*Is the python path environment variable set correctly?
*
*All OS: PYTHONPATH*
*
*
*Is the library path environment variable set correctly?*
*Linux: LD_LIBRARY_PATH*
*Windows: PATH*
*MacOSX: DYLD_LIBRARY_PATH*
I had set the path in .bashrc and .profile
export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python2.7/dist-packages
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
Thank you.
Regards,
Tanaga Biru

Hi Tanaga, follow these steps :
*1.* Uninstall gnuradio with "sudo make uninstall"
*2.* Remove all the "export"(s) in the .profile and .bashrc files or
better leave only :
/export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python2.7/dist-packages/
in the .bashrc file
*3.* go back in the root folder of the gnuradio source and remove the
"build" folder you used to compile gnuradio.
/rm -rf build//
*4.* Edit the *CMakeLists.txt* file in the gnuradio root folder in the
following way as described here :
https://bbs.archlinux.org/viewtopic.php?id=147452
replace :
// /find_package(PythonLibs)/
with :
/find_package(PythonLibs <your-python-version>)/
you'll get the python version from your shell
*5.* rebuiild and install gnuradio in the usual way. All the issues
should be fixed now....Let me know....
Kind Regards,
Arturo
