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).
- Ryan 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 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 ?
