Re: [Discuss-gnuradio] Import Error running companion after upgrade to Fedora 27

[Jeff Long]

Import errors can happen for a variety of reasons, even if the packages 
are still in the right place. A common reason is that libraries provided 
by rpms, and that gnuradio depends on, have changed. Since Boost has 
changed to version 1.64 in Fedora 27, you'll have to rebuild gnuradio.
