Hello,

I am attempting to use GNU radio with a ZedBoard by following the  
tutorial here:

[http://gnuradio.org/redmine/projects/gnuradio/wiki/Zynq](http://gnuradio.org/redmine/projects/gnuradio/wiki/Zynq)

While using bitbake to create an OS to run on the board, I get an  
error while compiling uhd-3.6.2:

[these errors repeat hundreds of times]

Does anyone know what this means, why I am getting this, or how to fix  
it?

Thank you!

Chris
