From 287d6d5d3aef2fd8b7f394cf233810bb2f7da6e2 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Bj=C3=B8rn=20Forsman?= Date: Thu, 16 Oct 2014 20:08:52 +0200 Subject: [PATCH] libpcap: pass --with-pcap=linux for all linux systems ...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. --- pkgs/development/libraries/libpcap/default.nix | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/pkgs/development/libraries/libpcap/default.nix b/pkgs/development/libraries/libpcap/default.nix index 77b0d3975c0b..c6f1f1a1ddcb 100644 --- a/pkgs/development/libraries/libpcap/default.nix +++ b/pkgs/development/libraries/libpcap/default.nix @@ -10,8 +10,7 @@ stdenv.mkDerivation rec { nativeBuildInputs = [ flex bison ]; - # Apparently, 32 bit systems need this forced?
