As pointed out elsewhere [1], you can work around the libxml2 issue by running
GRC while forcing MacPorts’ libxml2 library to load first via:
{{{
DYLD_INSERT_LIBRARIES=/opt/local/lib/libxml2.dylib gnuradio-companion
}}}
And, otherwise, both UHD and GNU Radio seem to work on 10.10 beyond the recent
AVX compile issue pointed out in [2] (which also has a work-around). So, if
you’re an OSX user of UHD and GNU Radio who needs the latest and greatest, you
can get it all working if you’re willing to do some work-arounds. We’re
working on fixing all of these issues so that work-arounds are not required. -
