Jeremy,
I went through this recently and I believe you need to build UHD
manually, assuming you are using pre-built UHD binaries. If you’ve
installed it, DPDK support should be detected when you build the UHD
driver (the output of cmake should indicate if it finds it or not).

I recently bought a X310 usrp and a 82599ES 10-Gigabit SFI/SFP+
Network Interface Card (the one recommended on the Ettus Website).
I first set my connections and a benchmark test shows a lot of dropped
samples and some overflows.
So i decided to try using dpdk to improve my setup.
I have UHD 3.14.1.1 and I installed dpdk with my apt package manager
(dpdk version 17.11.9).
I followed this guide
https://kb.ettus.com/Getting_Started_with_DPDK_and_UHD
<https://kb.ettus.com/Getting_Started_with_DPDK_and_UHD> and when I
run the benchmark with use_dpdk argument, I got the following:
|[WARNING] [DPDK] Detected use_dpdk argument, but DPDK support not
built in.|
I really don't understand what's wrong. I tried so many things. I
tried with dpdk 18 and went back to 17 because it didn't solve anything.
Could anyone help me with that please ?
Jeremy
I don't think the DPDK support in UHD is "mainstream" yet (perhaps in
3.15?) so the packaged binaries don't have support for it.
