From: Willem de Bruijn Date: Mon, 22 Jul 2013 00:02:38 +0000 (-0400) Subject: build: fail in configure on missing dependency with --enable-bpf-compiler X-Git-Tag: v1.4.20~3 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c18f2ce7f61c7e7ae3bd207ef6337a1be0c7aff3;p=thirdparty%2Fiptables.git build: fail in configure on missing dependency with --enable-bpf-compiler The build of utils/nfbpf_compile depends on libpcap. If configure is run with --enable-bpf-compiler, the script succeeds, but make fails. This small patch adds a test for the dependency (libpcap) in configure and fails hard if not found.
