Re: [Discuss-gnuradio] UHD won't work with GRC

[Josh Blum]

The configure check is very simple. Just make sure that uhd.pc is in
your PKG_CONFIG_PATH, and that if you look at uhd.pc, the version should
read 002.<something>. If not, then you didnt update or install the
latest uhd, that could be another reason its getting rejected.
