Re: [Discuss-gnuradio] Trouble With UHD Tune Request

Thanks for the reply Josh! That definitely seems to have solved part of
my problem. I did still have to include the ${UHD_INCLUDE_DIRS} directly
(added include_directories(/usr/local/include/uhd/types) to my
CMakeLIsts.txt). If you have a suggestion that might make this
unnecessary I will give it a shot but this I can live with. I am now
able to compile the Module containing my Block successfully. However,
when I run another block from the module or try to compile my C++
flowgraphs I get the same errors. Any thoughts? I can't rule out an
error in my code but this wouldn't explain the GRC error.
