From 205643a3454fee967bd7fbc8e1668f6d18a83ce3 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Sat, 8 Jun 2013 23:45:36 +0000 Subject: [PATCH] libpcap: fix build failure related to libnl3 When libpcap detects that libnl3 is available, it hardcodes the fact of using -I/usr/include/libnl3, which is completely wrong in cross-compilation. This commit fixes that, by removing this hardcoded include path, and by passing an appropriate -I option from libpcap.mk. The original issue has been reported upstream at https://github.com/the-tcpdump-group/libpcap/issues/305.
