This hoses up every new app developer. Especially me, as I used DPDK before the PCI probe behavior was changed between versions and got totally lost when it broke. You need the following: Build Configuration: CONFIG_RTE_BUILD_COMBINE_LIBS=y Linker Flags (LDFLAGS): -Wl,--whole-archive -Wl,--start-group -ldpdk -Wl,--end-group -Wl,--no-whole-archive Sincerely.
