Ask for help about installing gnu-radio

GNU Radio
1

Hello,
After installing the development package of gnu-radio, I got the
following
ImportError when running qa_cvsd_vocoder.py in gr-cvsd-vocoder.
Actually, I met
similar problems of running python code in other folders. But the
libgromnithread.so actually exists the /usr/local/lib. I had added this
path to
the PATH environment variable.

I am not sure if my installing is correct.

thanks a lot.

Give a ‘sudo ldconfig’ a try.
