Installation instructions for nftables
======================================

 Prerequisites
 =============

  - build tooling: glibc headers, gcc, autotools, automake, libtool, pkg-config.

  - libmnl: git://git.netfilter.org/libmnl.git

  - libnftnl: git://git.netfilter.org/libnftnl.git

  - flex

  - bison

  - libgmp: alternatively, see mini-gmp support below.

  - libreadline or libedit or linenoise: required by interactive command line

  - optional: libxtables: required to interact with iptables-compat

  - optional: libjansson: required to build JSON support

  - optional: asciidoc: required for building man-page

 Configuring and compiling
 =========================

 Run "sh autogen.sh" to generate the configure script, then:

 sh configure [options]

 --prefix=

        The prefix to put all installed files under. It defaults to
        /usr/local, so the binaries will go into /usr/local/bin, sbin,
        manpages into /usr/local/share/man, etc.

 --datarootdir=

	The base directory for arch-independent files. Defaults to
	$prefix/share.

 --with-unitdir=

	Directory for systemd unit files. Defaults to the value obtained from
	pkg-config for systemd.pc, and ${prefix}/lib/systemd/system as a
	fallback.

 --disable-debug

	Disable debugging

 --with-mini-gmp

	Use builtin mini-gmp instead of linking with a shared libgmp.
	This is useful for embedded platforms optimizing for size and
	having no other use for libgmp.
	Note: This decreases the debugging verbosity in some files.

 --with-xtables

	For libxtables support to interact with the iptables-compat
	utility.

 --without-cli

	To disable interactive command line support, ie. -i/--interactive.

 --with-cli=readline

	To enable interactive command line support with libreadline.

 --with-cli=linenoise

	To enable interactive command line support with linenoise.

 --with-cli=editline

	To enable interactive command line support with libedit.

 --with-json

	To enable JSON support, this requires libjansson.

 Run "make" to compile nftables, "make install" to install it in the
 configured paths.

 Python support
 ==============

 CPython bindings are available for nftables under the py/ folder.  They can be
 installed using pip:

	python -m pip install py/

 A legacy setup.py script can also be used:

	( cd py && python setup.py install )

 However, this method is deprecated.
