From: Gustavo Zacarias Date: Tue, 26 Jun 2012 04:19:50 +0000 (+0000) Subject: libpcap: canusb support needs pthreads X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c69be6d2abe8f8e265f92494867e2c7e1519dd08;p=buildroot.git libpcap: canusb support needs pthreads canusb support in libpcap uses pthreads but the configure script doesn't account for -lpthread usage so it doesn't get added into LIBS which in turn doesn't add the appropiate entry in pcap-config, causing build failures for programs that link to libpcap that don't use pthreads themselves (for example tcpdump). Also add the conditional dependency on BR2_PACKAGE_LIBUSB for canusb.
