Hi Mark,
as far as I can tell, you've recompiled UHD, but you did not recompile
GNU Radio to link against that UHD (I don't know if you've updated UHD
since your last compilation of GNU Radio, so this might pose a problem).
>And yes, I have run the ~/gnuradio/src/prefix/setup_env.sh first.
Does that mean you've /run/ it, or did you /source/ it? The first
wouldn't have an effect, because it would set up the correct paths for
the duration of the script running – and that script immediately exits.
Sourcing the file, however, would make the changes permanent to your shell.
Also, it's important that you did the sourcing before compiling UHD –
otherwise, the build process might use system libraries that it
shouldn't use.
Best regards,
Marcus
