37 |
# Script for automatically preparing the sources for compilation by |
38 |
# performing the myriad of necessary steps. The script attempts to |
39 |
# detect proper version support, and outputs warnings about particular |
40 |
# systems that have autotool peculiarities. |
41 |
# |
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. |
46 |
# |
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 |
50 |
# autoreconf. |
51 |
# |
52 |
# The AUTORECONF, AUTOCONF, AUTOMAKE, LIBTOOLIZE, ACLOCAL, AUTOHEADER |
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. |
57 |
# |
58 |
# Examples: |
59 |
# |
60 |
# To obtain help on usage: |
61 |
# ./autogen.sh --help |
62 |
# |
63 |
# To obtain verbose output: |
64 |
# ./autogen.sh --verbose |
65 |
# |
66 |
# To skip autoreconf and prepare manually: |
67 |
# AUTORECONF=false ./autogen.sh |
68 |
# |
69 |
# To verbosely try running with an older (unsupported) autoconf: |
70 |
# AUTOCONF_VERSION=2.50 ./autogen.sh --verbose |
