autotools是个系列工具，首先确认你的Ubuntu系统是否安装了以下工具（可以通过which命令查看）：
aclocal
autoscan
autoconf
autoheader
automake
---------------------------------------------------------------------------------
安装方法：
[email protected]:~$ sudo apt-get install autoconf
装完后，用which 命令查看
如下：
[email protected]:~$ which aclocal
/usr/bin/aclocal
[email protected]:~$ which autoscan
/usr/bin/autoscan
[email protected]:~$ which autoconf
/usr/bin/autoconf
[email protected]:~$ which auto header
[email protected]:~$ automake
automake: `configure.ac‘ or `configure.in‘ is required
[email protected]:~$ which automake
/usr/bin/automake
------------------------------------------------------------------------------
下面开始来生成一个Makefile:
建立以下代码文件：
hello.cxx hello.h
以下直接贴出我的操作过程：
[email protected]:~/work/test$ autoscan
[email protected]:~/work/test$ ls
autoscan.log configure.scan hello.cxx hello.h
[email protected]:~/work/test$ mv configure.scan configure.ac
[email protected]:~/work/test$ ls
autoscan.log configure.ac hello.cxx hello.h
[email protected]:~/work/test$ gedit configure.ac
[email protected]:~/work/test$ aclocal
[email protected]:~/work/test$ ls
aclocal.m4 autoscan.log configure.ac~ hello.h
autom4te.cache configure.ac hello.cxx
[email protected]:~/work/test$ autoconf
[email protected]:~/work/test$ ls
aclocal.m4 autoscan.log configure.ac hello.cxx
autom4te.cache configure configure.ac~ hello.h
[email protected]:~/work/test$ autoheader
[email protected]:~/work/test$ ls
aclocal.m4 autoscan.log configure configure.ac~ hello.h
autom4te.cache config.h.in configure.ac hello.cxx
[email protected]:~/work/test$ touch makefile.am
[email protected]:~/work/test$ gedit makefile.am
[email protected]:~/work/test$ automake -a
configure.ac:6: installing `./install-sh‘
configure.ac:6: installing `./missing‘
makefile.am: installing `./depcomp‘
[email protected]:~/work/test$ ls
aclocal.m4 config.h.in configure.ac~ hello.h makefile.am~
autom4te.cache configure depcomp install-sh makefile.in
autoscan.log configure.ac hello.cxx makefile.am missing

configure: creating ./config.status
config.status: creating makefile
config.status: creating config.h
config.status: executing depfiles commands
[email protected]:~/work/test$ make hello
g++ -DHAVE_CONFIG_H -I. -g -O2 -MT hello.o -MD -MP -MF .deps/hello.Tpo -c -o hello.o hello.cxx
mv -f .deps/hello.Tpo .deps/hello.Po
g++ -g -O2 -o hello hello.o
[email protected]:~/work/test$
其中：
[email protected]:~/work/test$ gedit configure.ac编辑configure.ac内容为
# -*- Autoconf -*-
# Process this file with autoconf to produce a configure script.
AC_PREREQ([2.68])
AC_INIT(hello,1.0)
AM_INIT_AUTOMAKE(hello,1.0)
AC_CONFIG_SRCDIR([hello.cxx])
AC_CONFIG_HEADERS([config.h])
# Checks for programs.
AC_PROG_CXX
AC_PROG_CC
# Checks for libraries.
# Checks for header files.
# Checks for typedefs, structures, and compiler characteristics.
# Checks for library functions.
AC_CONFIG_FILES([makefile])
AC_OUTPUT
[email protected]:~/work/test$ gedit makefile.am编辑makefile.am的内容为：
AUTOMAKE_OPTIONS=foreign
bin_PROGRAMS=hello
hello_SOURCES=hello.cxx
最后的执行.configure我们得到了makefile文件，使用make命令就输出了可执行文件hello
