Re: [Discuss-gnuradio] gnu radio installation on Mac via MacPorts

Hi Vipin - OK; interesting. Can you try the following:

{{{
sudo port -f deactivate uhd

sudo port install uhd-devel

}}}

then if those work, try running "uhd_fft" again & hopefully it will work. If not, send me the crash log off-list & we'll try something else. - MLD

Actually, the install works fine but I am running into segmentation violation while running top_block.py through GRC GUI or uhd_fft on command line. Somewhere I am guessing Python versions are getting messed up. Here is the crash log after running 'uhd_fft -f 868M -s 10M'; how do I figure out what is causing the crash?
