7 dnl Inspiration from http://autoconf-archive.cryp.to
9 dnl tell automake the this script is for rrdtool
11 dnl Minimum Autoconf version required.
12 AC_PREREQ(2.59)
14 dnl the official version number is
15 dnl a.b.c
16 AC_INIT([rrdtool],[1.4.2])
18 dnl for testing a numberical version number comes handy
19 dnl the released version are
20 dnl a.bccc
21 dnl the devel versions will be something like
22 dnl a.b999yymmddhh
23 NUMVERS=1.4002
24 AC_SUBST(NUMVERS)
26 dnl for the linker to understand which versions the library are compatible with
27 dnl each other we must keep a separate library version cout of the format c:r:a.
28 dnl - if only implementation changed but all interfaces are kept, do r++
29 dnl - if only functionality was added do c++,r=0,a++
30 dnl - if any functionality was removed do c++,r=0,a=0.
