图解aclocal、autoconf、automake、autoheader、configure

1.autoscan (autoconf): 扫描源代码以搜寻普通的可移植性问题,比如检查编译器,库,头文件等,生成文件configure.scan,它是configure.ac的一个雏形。
2.aclocal (automake):根据已经安装的宏,用户定义宏和acinclude.m4文件中的宏将configure.ac文件所需要的宏集中定义到文件 aclocal.m4中。aclocal是一个perl 脚本程序,它的定义是:“aclocal - create aclocal.m4 by scanning configure.ac”
user input files   optional input     process          output files
================   ==============     =======          ============
                    acinclude.m4 - - - - -.
                                          V
                                      .-------,
configure.ac ------------------------>|aclocal|
                 {user macro files} ->|       |------> aclocal.m4
                                      `-------'
3.autoheader(autoconf): 根据configure.ac中的某些宏,比如cpp宏定义,运行m4,声称config.h.in
user input files    optional input     process          output files
================    ==============     =======          ============
                    aclocal.m4 - - - - - - - .
                                             |
                                             V
                                     .----------,
configure.ac ----------------------->|autoheader|----> autoconfig.h.in
                                     `----------'
4.automake: automake将Makefile.am中定义的结构建立Makefile.in,然后configure脚本将生成的Makefile.in文件转换为Makefile。如果在configure.ac中定义了一些特殊的宏,比如AC_PROG_LIBTOOL,它会调用libtoolize,否则它会自己产生config.guess和config.sub
user input files   optional input   processes          output files
================   ==============   =========          ============
                                     .--------,
                                     |        | - - -> COPYING
                                     |        | - - -> INSTALL
                                     |        |------> install-sh
                                     |        |------> missing
                                     |automake|------> mkinstalldirs
configure.ac ----------------------->|        |
Makefile.am  ----------------------->|        |------> Makefile.in
                                     |        |------> stamp-h.in
                                 .---+        | - - -> config.guess
                                 |   |        | - - -> config.sub
                                 |   `------+-'
                                 |          | - - - -> config.guess
                                 |libtoolize| - - - -> config.sub
                                 |          |--------> ltmain.sh
                                 |          |--------> ltconfig
                                 `----------'
5.autoconf:将configure.ac中的宏展开,生成configure脚本。这个过程可能要用到aclocal.m4中定义的宏。
user input files   optional input   processes          output files
================   ==============   =========          ============
                   aclocal.m4 - - - - - -.
                                         V
                                     .--------,
configure.ac ----------------------->|autoconf|------> configure ----->autoconfig.h,Makefile

    Give it a look, if you wish to dance

    Se a QMP for bastante maior do que você souber que é possível que pagar, pergunte se eles estão dispostos a
    negociar os mínimos.

    nnd,我刚刚找了资料看这些工具,你丫就搞这个,真是想到我心窝里了。

    这个图很形象,用字符构成的图还真不容易啊。
