SDB:AutoTools 简单应用

简述

本文将演示使用 autotools 的方法

准备

在自己准备的路径下建立目录，例如

$ mkdir auto

$ cd auto

$ mkdir test

$ cd test

写c文件

例如将写一个 autotool 文件

# include <stdio.h>

void main()
{  
 printf("Welcome to use AutoTools!");
}

产生configure文件

产生一个 configure.in 的原型，产生 configure.scan 　

$ autoscan

$ ls

configure.scan autotool.c 

2.edit configure.scan 内容如下

AC_INIT(autotool.c)
AM_INIT_AUTOMAKE(autotool, 1.0)  
AC_PROG_CC  
AC_OUTPUT(Makefile)

3.产生 aclocal.m4 及 configure

$ aclocal

$ Autoconf

$ ls

aclocal.m4  configure  configure.in autotool.c

产生makefile

1.编辑 makefile.am 文件

bin_PROGRAMS= autotool
autotool_SOURCES= autotool.c

2. 执行 Automake --add-missing

$ Automake --add-missing

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

Automake: configure.in: installing `./mkinstalldirs'

Automake: configure.in: installing `./missing'

3. 执行 ./configure

$ ./configure

checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking for gcc... gcc
checking for C compiler default output file name... a.out
checking whether the C compiler works... yes
checking whether we are cross compiling... no
checking for suffix of executables...
checking for suffix of object files... o
checking whether we are using the GNU C compiler... yes
checking whether gcc accepts -g... yes
checking for gcc option to accept ANSI C... none needed
checking for style of include used by make... GNU
checking dependency style of gcc... gcc3
configure: creating ./config.status
config.status: creating Makefile
config.status: executing depfiles commands

实验

$ make

.               autoscan.log   configure.in  autotool.c     Makefile.am
..              config.log     depcomp       autotool.o     Makefile.in
aclocal.m4      config.status  .deps         install-sh  missing
autom4te.cache  configure      autotool      Makefile

此时就已经成功完成！
