12: # Usage:
13: # [VAR=<value>] ./autogen.sh [<configure-args>]
14: #
15: # This script generates the ./configure script using GNU automake and
16: # GNU autoconf. It tries to be smart in finding the correct/usable/available
17: # installed versions of these tools on your system.
18: #
19: # In addition, it enables or disables the "de-ANSI-fication" support of GNU
20: # automake, which is supported up to autoconf 1.11.x an has been removed
21: # in automake 1.12 -- make sure to use a version of automake supporting it
22: # when generating distribution archives!
23: #
24: # The following strategy is used for each of aclocal, autoheader, automake,
25: # and autoconf: first, "tool" (the regular name of the tool, e. g. "autoconf"
26: # or "automake") is checked. If this fails, "tool<major><minor>" (for example
27: # "automake16") and "tool-<major>.<minor>" (e. g. "autoconf-2.54") are tried
28: # with <major> being 2 for tool of GNU autoconf and 1 for tools of automake;
29: # <minor> is tried from 99 to 0. The first occurrence will be used.
30: #
31: # When you pass <configure-args> to autogen.sh it will call the generated
32: # ./configure script on success and pass these parameters to it.
33: #
34: # You can tweak the behaviour using these environment variables:
35: #
36: # - ACLOCAL=<cmd>, AUTOHEADER=<cmd>, AUTOMAKE=<cmd>, AUTOCONF=<cmd>
37: # Name and optionally path to the particular tool.
38: # - PREFIX=<path>
39: # Search the GNU autoconf and GNU automake tools in <path> first. If the
40: # generated ./configure script will be called, pass "--prefix=<path>" to it.
41: # - EXIST=<tool>
42: # Use <tool> to test for aclocal, autoheader etc. pp. ...
43: # When not specified, either "type" or "which" is used.
44: # - VERBOSE=1
45: # Output the detected names of the GNU automake and GNU autoconf tools.
46: # - GO=1
47: # Call ./configure even if no arguments have been passed to autogen.sh.
48: #
49: # Examples:
50: #
51: # - ./autogen.sh
52: # Generates the ./configure script.
53: # - GO=1 ./autogen.sh
54: # Generates the ./configure script and runs it as "./configure".
55: # - VERBOSE=1 ./autogen.sh --with-ident
56: # Show tool names, generates the ./configure script, and runs it with
57: # these arguments: "./configure --with-ident".
58: # - ACLOCAL=aclocal-1.6 GO=1 PREFIX=$HOME ./autogen.sh
59: # Uses "aclocal-1.6" as aclocal tool, generates the ./configure script,
60: # and runs it with these arguments: "./configure --prefix=$HOME".
