Greetings,

Trying to use usrp\_source in a C++ application; it seems there is a  
mismatch between where the headers are installed and where they are  
supposed to be installed.

The heqaders are installed in: include/gnuradio/gr\_uhd/  
but usrp\_source.h has an include:  
#include \<uhd/api.h\>

and gives compiler error.

As far as I can see I’m using the latest code: v3.6.4.1-989-g2caaabf8

Alex
