I'm guessing that the GNU Radio files are in /usr/ and the OsmoSDR files are in /usr/local. In that case, GRC doesn't look for the blocks in /usr/local. To see if this is the problem, set the environment variable GRC_BLOCKS_PATH to /usr/local/share/gnuradio/grc/blocks/ (or wherever your blocks are) and start gnuradio-companion. If this works, then you can statically set this path in ~/.gnuradio/config.conf (see http://gnuradio.org/redmine/projects/gnuradio/wiki/GNURadioCompanion). This behaviour is already documented (Issue #606), but we get very few people who mix the source and binary builds. > When trying to import osmosdr directly in a python interpreter: the > first time I issue the import statement, I get "ImportError: > /usr/lib/libgnuradio-blocks-3.7.1.1.so.0.0.0: undefined symbol: > volk_64u_byteswap_u".

Well, if GNU Radio doesn't work you won't be able to use gr-osmosdr either. I can't think of a solution off the top of my head, though. Perhaps this is a case where pybombs might be able to help you. If you want to try this, do the following: - Uninstall everything GNU Radio- and OsmoSDR-related - Run git clone git://github.com/pybombs/pybombs cd pybombs ./pybombs install gnuradio and then ./pybombs install gr-osmosdr http://gnuradio.org/redmine/projects/pybombs/wiki/QuickStart will guide you.
