Linux C一个Autotools的最简单例子

1、准备:
     需要工具autoscan aclocal autoheader automake autoconf make 等工具.
2、测试程序编写：
     建立目录：mkdir include src
     编写程序：include/str.h#include <stdio.h>
int str（char *string）;编写程序：src/str.c#include "str.h"
//print string
int str（char *string）{
        printf（" ----PRINT STRING---- "%s" ",string）;
        return 0;
}//interface of this program
int main（int argc , char **argv）{
        char str_read[1024];
        printf（"Please INPUT something end by [ENTER] "）;
        scanf（"%s",str_read）;
        return str（str_read ）;
}3、生成configure.ac
    configure.ac是automake的输入文件，所以必须先生成该文件。
    执行命令：[root@localhost str]# ls
include src
[root@localhost str]# autoscan
autom4te: configure.ac: no such file or directory
autoscan: /usr/bin/autom4te failed with exit status: 1
[root@localhost str]# ls
autoscan.log configure.scan include src
[root@localhost str]# cp configure.scan configure.ac 修改 configure.ac#                                               -*- Autoconf -*-
# Process this file with autoconf to produce a configure script.AC_PREREQ（2.59）
AC_INIT（FULL-PACKAGE-NAME, VERSION, BUG-REPORT-ADDRESS）
AC_CONFIG_SRCDIR（[include/str.h]）
AC_CONFIG_HEADER（[config.h]）# Checks for programs.
AC_PROG_CC# Checks for libraries.# Checks for header files.# Checks for typedefs, structures, and compiler characteristics.# Checks for library functions.
AC_OUTPUT修改AC_INIT（FULL-PACKAGE-NAME, VERSION, BUG-REPORT-ADDRESS）为AC_INIT（str,0.0.1, [bug@sounos.org]）FULL-PACKAGE-NAME 为程序名称，VERSION为当前版本， BUG-REPORT-ADDRESS为bug汇报地址
    添加AM_INIT_AUTOMAKE
    添加AC_CONFIG_FILES（[Makefile]）#                                               -*- Autoconf -*-
# Process this file with autoconf to produce a configure script.AC_PREREQ（2.59）
#AC_INIT（FULL-PACKAGE-NAME, VERSION, BUG-REPORT-ADDRESS）
AC_INIT（str, 0.0.1, [bug@sounos.org]）
AM_INIT_AUTOMAKE
AC_CONFIG_SRCDIR（[include/str.h]）
AC_CONFIG_HEADER（[config.h]）# Checks for programs.
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_OUTPUT4、执行aclocal[root@localhost str]# aclocal
/usr/share/aclocal/libfame.m4:6: warning: underquoted definition of AM_PATH_LIBFAME
