Hello Henning, To make it easy to update UHD versions Ettus has a private package archive, PPA, for Ubuntu. You can update your UHD using the following commands. You will still need to recompile GNU Radio (most accurately gr-uhd) to make it compatible with the newer UHD's interface.
# Remove existing packages sudo apt-get remove uhd libuhd003 libuhd-host libuhd-dev # Install the new repository, update package lists, and install the up to date versions sudo apt-add-repository ppa:ettusresearch/uhd sudo apt-get update sudo apt-get install libuhd003 libuhd-host libuhd-dev # Check installed uhd version, it will be on the first line of the output. It should read release 3.9.2 uhd_find_devices Regards, Derek On Thu, Mar 3, 2016 at 5:58 AM, Marcus Müller <[email protected]> wrote: > The UHD you're using is 3.5.5.
