[root@localhost test3]# cat add.h
#ifndef _ADD_H_
#define _ADD_H_


extern int add(int, int);


#endif

[root@localhost test3]# cat add.c
#include "add.h"


int add(int a, int b)
{
        return a + b;
}

[root@localhost test3]# cat main.c
#include 
#include "add.h"

int main()
{
        int a, b, c;


        a = 5;
        b = 6;


        c = add(a, b);


        printf("c = %d ", c);


        return 0;
}

[root@localhost test3]# gcc -shared -o libadd.so add.c


1、执行autoscan
[root@localhost test3]# autoscan
[root@localhost test3]# ls
add.c  add.h  autoscan.log  configure.scan  main.c


2、编辑configure.in
[root@localhost test3]# mv configure.scan configure.in


[root@localhost test3]# cat configure.in
#                                               -*- Autoconf -*-
# Process this file with autoconf to produce a configure script.


AC_PREREQ([2.63])
AC_INIT([main], [1.0], [yww680169@126.com])
AM_INIT_AUTOMAKE(main, 1.0)
AC_CONFIG_SRCDIR([main.c])
AC_CONFIG_HEADERS([config.h])


# Checks for programs.
AC_PROG_CC


# Checks for libraries.

make  all-am
make[1]: Entering directory `/home/xiaowan/Desktop/test3'
gcc -DHAVE_CONFIG_H -I.     -g -O2 -MT main.o -MD -MP -MF .deps/main.Tpo -c -o main.o main.c
mv -f .deps/main.Tpo .deps/main.Po
