Subject: configure: make libmnl and libnftnl hard requirements
X-Git-Tag: v1.6.1~88
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=3d202e5d23df1728eb035e011a4f1c46488f1c17;p=thirdparty%2Fiptables.git

configure: make libmnl and libnftnl hard requirements

Iptables building is broken if either libmnl or libnftnl
is not installed on the system.

Configure script actually checks if libmnl and libnftnl are installed,
but doesn't exit if they are not.
