37
# Script for automatically preparing the sources for compilation by
38
# performing the myrid of necessary steps. The script attempts to
39
# detect proper version support, and outputs warnings about particular
40
# systems that have autotool peculiarities.
42
# Basically, if everything is set up and installed correctly, the
43
# script will validate that minimum versions of the GNU Build System
44
# tools are installed, account for several common configuration
45
# issues, and then simply run autoreconf for you.
47
# If autoreconf fails, which can happen for many valid configurations,
48
# this script proceeds to run manual preparation steps effectively
49
# providing a POSIX shell script (mostly complete) reimplementation of
52
# The AUTORECONF, AUTOCONF, AUTOMAKE, LIBTOOLIZE, ACLOCAL
53
# environment variables and corresponding _OPTIONS variables (e.g.
54
# AUTORECONF_OPTIONS) may be used to override the default automatic
55
# detection behaviors. Similarly the _VERSION variables will override
56
# the minimum required version numbers.
60
# To obtain help on usage:
63
# To obtain verbose output:
64
# ./autogen.sh --verbose
66
# To skip autoreconf and prepare manually:
67
# AUTORECONF=false ./autogen.sh
69
# To verbosely try running with an older (unsupported) autoconf:
70
# AUTOCONF_VERSION=2.50 ./autogen.sh --verbose
