Hi Julian,

Does the segfault go away if you build gr-ettus with the flag
-DCMAKE_BUILD_TYPE=Debug?

It works…which is good but a brief explanation would be great to add it to the report.

Just for sanity, this is the post I used to get all the settings correct.
So far it’s the only documentation I can find for how to set up UHD 4.0 with fosphor.

http://ettus.80997.x6.nabble.com/USRP-users-setting-up-gr-fosphor-on-uhd-4-td16532.html

I also had some issues with the QT window locking up the widget controls, so I used zmq sockets to pipe the 2 byte streams into another flowgraph that hosts the fosphor display.

When I rebuilt gr-ettus with the flag -DCMAKE_BUILD_TYPE=Debug, the graph flow runs and the data is being displayed just fine. I do not get any segmentation fault this time.
