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". 61# 62 63Search() 64{ 65 [ $# -eq 2 ] || exit 1 66 67 searchlist="$1" 68 major="$2" 69 minor=99 70 71 [ -n "$PREFIX" ] && searchlist="${PREFIX}/$1 ${PREFIX}/bin/$1 $searchlist" 72 73 for name in $searchlist; do 74 $EXIST "${name}" >/dev/null 2>&1 75 if [ $?
