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
int str(char *string);

编写程序：src/str.c

#include "str.h"
//print string
int str(char *string){
printf("\n----PRINT STRING----\n\"%s\"\n",string);
return 0;
}

//interface of this program
int main(int argc , char **argv){
char str_read[1024];
printf("Please INPUT something end by [ENTER]\n");
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_OUTPUT

4、执行aclocal
