Configure，Makefile.am, Makefile.in, Makefile文件之间关系

2011-12-29 11:59 453 查看

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。
yoursourcefiles-->[autoscan*]-->[configure.scan]-->configure.ac
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-createaclocal.m4byscanningconfigure.ac”

acinclude.m4-----.

.-------,
configure.ac------------------------>|aclocal|
{usermacrofiles}->||------>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

.----------,
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

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。

实例：

在/hello/目录下创建一个hello.c文件，并编译运行它：
#cd/hello/
(1)编写源文件hello.c：
#include<stdio.h>

intmain(intargc,char**argv)

{

printf("Hello,GNU!n");

return0;

}
[litao@vm0000131hello]$ll

total4

-rw-rw-r--1litaolitao68Aug1212:02hello.c
一、autoscan
[litao@vm0000131hello]$autoscan

autom4te:configure.ac:nosuchfileordirectory

autoscan:/usr/bin/autom4tefailedwithexitstatus:1

[litao@vm0000131hello]$ll

total8

-rw-rw-r--1litaolitao0Aug1212:03autoscan.log

-rw-rw-r--1litaolitao457Aug1212:03configure.scan

-rw-rw-r--1litaolitao68Aug1212:02hello.c
已经生成了configure.scan，autoscan.log文件
将configure.scan修改为configure.in，最后修改的内容如下：
[litao@vm0000131hello]$mvconfigure.scanconfigure.in

[litao@vm0000131hello]$vimconfigure.in

#-*-Autoconf-*-

#Processthisfilewithautoconftoproduceaconfigurescript.

AC_PREREQ(2.59)

AC_INIT(FULL-PACKAGE-NAME,VERSION,BUG-REPORT-ADDRESS)

AC_CONFIG_SRCDIR([hello.c])

#AC_CONFIG_HEADER([config.h])

AM_INIT_AUTOMAKE(hello,1.0)

#Checksforprograms.

AC_PROG_CC

#Checksforlibraries.

#Checksforheaderfiles.

#Checksfortypedefs,structures,andcompilercharacteristics.

#Checksforlibraryfunctions.

AC_OUTPUT(Makefile)
二、acloacl

[litao@vm0000131hello]$aclocal

生成aclocal.m4和autom4te.cache(生成aclocal.m4的过程中涉及到configure.in)
[litao@vm0000131hello]$ll

total44

-rw-rw-r--1litaolitao31120Aug1212:08aclocal.m4

drwxr-xr-x2litaolitao4096Aug1212:08autom4te.cache

-rw-rw-r--1litaolitao0Aug1212:03autoscan.log

-rw-rw-r--1litaolitao496Aug1212:08configure.in

-rw-rw-r--1litaolitao68Aug1212:02hello.c
三、antoconf

[litao@vm0000131hello]$autoconf

生成configure(根据configure.in,和aclocal.m4)

[litao@vm0000131hello]$ll

total168

-rw-rw-r--1litaolitao31120Aug1212:08aclocal.m4

drwxr-xr-x2litaolitao4096Aug1212:11autom4te.cache

-rw-rw-r--1litaolitao0Aug1212:03autoscan.log

-rwxrwxr-x1litaolitao122297Aug1212:11configure

-rw-rw-r--1litaolitao496Aug1212:08configure.in

-rw-rw-r--1litaolitao68Aug1212:02hello.c

四、编写Makefile.am：
AUTOMAKE_OPTIONS=foreign

bin_PROGRAMS=hello

hello_SOURCES=hello.c
五、automake
生成Makefile.in，depcomp，install-sh，和missing(根据Makefile.am,和aclocal.m4)
[litao@vm0000131hello]$automake

configure.in:requiredfile`./install-sh'notfound

configure.in:requiredfile`./missing'notfound

Makefile.am:requiredfile`./depcomp'notfound

[litao@vm0000131hello]$automake--add-missing

configure.in:installing`./install-sh'

configure.in:installing`./missing'

Makefile.am:installing`./depcomp'

[litao@vm0000131hello]$ll

lrwxrwxrwx1litaolitao31Aug1212:16missing->/usr/share/automake-1.9/missing
六、configure

生成Makefile，config.log，和config.status
