Re: [Discuss-gnuradio] segfault

Hi Michele - It looks like there are multiple GNU Radio installs being
caught in the execution: /usr/local/lib/ and /usr/lib/x86_64-linux-gnu/
:

On Mac OS X this dual-linkage -could- cause issues depending on the
library linkage (flat or 2-level namespace; but, it likely would
anyway); I assume the same on Linux. I'd suggest limiting the number of
GR installs to just 1, and/or just making sure that any dependency is
linked to all of the correct GR libraries (those from the same install).

Good luck! - MLD
