2 dnl RRDtool AutoConf script ...
3 dnl ---------------------------
5 dnl Created by Jeff Allen, Tobi Oetiker, Blair Zajac
7 dnl Inspiration from http://autoconf-archive.cryp.to
9 dnl tell automake the this script is for rrdtool
10 dnl the official version number is
12 AC_INIT([rrdtool],[1.2.19])
13 dnl for testing a numberical version number comes handy
14 dnl the released version are
16 dnl the devl versions will be something like
22 AC_CONFIG_HEADERS([rrd_config.h])
24 dnl all our local stuff like install scripts and include files
28 dnl determine the type of system we are running on
32 AC_PREFIX_DEFAULT( /usr/local/rrdtool-$PACKAGE_VERSION )
34 dnl Minimum Autoconf version required.
