Linux工具之autogen.sh
从标题就可以看出了，autogen.sh是个shell脚本，它的作用就是将前一篇Linux工具之autoconf和automake讲的自动产生Makefile的过程集成到脚本中，简化操作。
接下来看看如何操作，直接上代码：
#!/bin/sh
echo
echo ... helloworld autogen ...
echo
MISSING=""
env aclocal --version >/dev/null 2>&1
if [ $? -eq 0 ];then
ACLOCAL=aclocal
else
MISSING="$MISSING aclocal"
fi
env autoconf --version > /dev/null 2>&1
if [ $? -eq 0 ];then
AUTOCONF=autoconf
else
MISSING="$MISSING autoconf"
fi
env autoheader --version > /dev/null 2>&1
if [ $? -eq 0 ]; then
AUTOHEADER=autoheader
else
MISSING="$MISSING autoconf"
fi
env automake --version > /dev/null 2>&1
if [ $? -eq 0 ];then
AUTOMAKE=automake
else
MISSING="$MISSING automake"
fi
env libtoolize --version > /dev/null 2>&1
if [ $? -eq 0 ];then
TOOL=libtoolize
else
env glibtoolize --version > /dev/null 2>&1
if [$? -eq 0 ];then
TOOL=glibtoolize
else
MISSING="$MISSING libtoolize/glibtoolize"
fi
fi
env tar -cf /dev/null /dev/null > /dev/null 2>&1
if [ $? -ne 0 ];then
MISSING="$MISSING tar"
fi
if [ "x$MISSING" != "x" ];then
echo "ABORTING."
echo
echo "The following build tools are missing:"
echo
for pkg in $MISSING;do
echo " * $pkg"
done
echo
echo "please install them and try again."
echo

echo Running $ACLOCAL
$ACLOCAL
echo Running $AUTOHEADER
$AUTOHEADER
echo Running $TOOL
$TOOL
echo Running $AUTOCONF
$AUTOCONF
echo Running $AUTOMAKE
$AUTOMAKE --add-missing --force-missing --copy --foreign
echo
echo "Please proceed with configuring, compiling and installing"如脚本所示， 先检测命令aclocal，autoconf，autoheader，automake，libtoolize，tar是否存在，之后再按照上篇的步骤来执行这几个命令；当然在执行脚本前配置文件configure.ac和Mafile.am还是必须的。
configure.ac
# -*- Autoconf -*-

rm -f aclocal.m4 autoscan.log config.h config.log config.sub configure depcomp Makefile compile config.h.in config.status install-sh missing stamp-h1 config.guess config.h.in~ ltmain.sh
底层Makefile.am如下
AUTOMAKE_OPTIONS=foreign
bin_PROGRAMS=helloworld
helloworld_SOURCES=hello.c
helloworld_LDADD=
LIBS=-lm
INCLUDE=-I/usr/include源码文件hello.c如下
#include
int main()
{
printf("hello.\n");
return 0;
} 执行过程如下：
