Hi, It's true that there is "libdpdk" in the Requires.private section, and probably shouldn't - but at least on Debian stable with pkg-config 0.29 it works fine despite that: $ PKG_CONFIG_PATH=/tmp pkg-config --cflags libdpdk -include rte_config.h -march=corei7 -I/usr/include/dpdk/../x86_64-linux-gnu/dpdk -I/usr/include/dpdk Maybe a newer pkg-config version got smarter? Regardless we should look into it -- Kind regards, Luca Boccassi
