...instead of just for i686-linux. Without a --with-pcap= configure flag, the build system tries to auto-detect the backend by poking in /dev, /usr/include etc... In the pure nix world, this auto-detection fails. (Good, we don't want host details to leak into the build.) The end result of this (failed) auto-detection; no packet capture possible: $ sudo tcpdump -i wlp2s0 tcpdump: live packet capture not supported on this system This fixes the above issue on 64-bit linux systems, and probably other architectures supported by linux.
