Hi Cédric, Following our previous discussion on the topic of building the controllers in-tree or out-of-tree, I was able to successfully build my controllers out-of-tree and they seem to work fine (with my custom application). One negative for building OOT is that the Ettus uhd_usrp_probe example does not know about your OOT library and so it does not recognize your OOT blocks. Also, I don't know how it would work with gnuradio. Rob
