libiio ad9361-iiostream example

I was planning on modifying the ad9361-iiostream example code to get familiar with the device, but when I run the sample application after building it, I get the following error when trying to initialize the IIO streaming channels. I was wondering if there was something else I need to configure to get this to work.

Thanks
