Hello again, Using meson and ninja made dpdk recognized by uhd cmake. I initially used the instructions from " https://doc.dpdk.org/guides-18.11/linux_gsg/build_dpdk.html";. However, when i tried to complete the uhd installation with make command, another problem was occurred (given below). Just to let you know, i couldn't make "CONFIG_RTE_BUILD_SHARED_LIB=y" with meson build (i dont know if it is necessary).

I am at the "Installing UHD" part in https://kb.ettus.com/Getting_Started_with_DPDK_and_UHD, so i dont have the uhd.conf file in root. In addition, i downloaded ixgbe driver at first, then switched it to vfio-pci <https://kb.ettus.com/Getting_Started_with_DPDK_and_UHD> Best Regards Berkay S.
