UNIX网络编程配置unp.h头文件

unp是unix 网络编程的缩写。

环境:centos7.4
下载地址:http://www.unpbook.com/unpv13e.tar.gz

1.下载命令

wget http://www.unpbook.com/unpv13e.tar.gz

2.解压unpv13e

ls -hl | grep unpv13e.tar.gz	# 查看压缩包
sudo tar -zxvf /root/unpv13e.tar.gz		# 解压路径填写为绝对路径,我这边用相对路径会提示*.c文件不是目录啥的

3.查看README

按照自述里的内容来配置:

Execute the following from the src/ directory:

    ./configure    # try to figure out all implementation differences

    cd lib         # build the basic library that all programs need
    make           # use "gmake" everywhere on BSD/OS systems

    cd ../libfree  # continue building the basic library
    make

    cd ../libroute # only if your system supports 4.4BSD style routing sockets
    make           # only if your system supports 4.4BSD style routing sockets

    cd ../libxti   # only if your system supports XTI
    make           # only if your system supports XTI

    cd ../intro    # build and test a basic client program
    make daytimetcpcli
    ./daytimetcpcli 127.0.0.1

3.1配置脚本

在unpv13e目录下执行.configure:

./configure

3.2创建lib库

cd lib
make

3.3创建libfree

cd ../libfree
make

make出错:
inet_ntop.c:60:9: error: argument ‘size’ doesn’t match prototype
size_t size;

解决方法:
inet_ntop.c的第60行:size_t size —> socklen_t size

3.4创建libroute

按照README说法,我的是CENTOS,不是BSD系统,所以可以直接跳到第五步。

cd ../libroute
make

make出错:
unproute.h:3:45: fatal error: net/if_dl.h: No such file or directory
#include <net/if_dl.h> /* sockaddr_sdl{} */

解决方法:
创建if_dl.h文件,复制以下内容到if_dl.h文件,将if_dl.h文件复制到/usr/include/net底下:

/* 
 * A Link-Level Sockaddr may specify the interface in one of two
 * ways: either by means of a system-provided index number (computed
 * anew and possibly differently on every reboot), or by a human-readable
 * string such as "il0" (for managerial convenience).
 * 
 * Census taking actions, such as something akin to SIOCGCONF would return
 * both the index and the human name.
 * 
 * High volume transactions (such as giving a link-level ``from'' address
 * in a recvfrom or recvmsg call) may be likely only to provide the indexed
 * form, (which requires fewer copy operations and less space).
 * 
 * The form and interpretation  of the link-level address is purely a matter
 * of convention between the device driver and its consumers; however, it is
 * expected that all drivers for an interface of a given if_type will agree.
 */

/*
 * Structure of a Link-Level sockaddr:
 */
struct sockaddr_dl {
    u_char  sdl_len;    /* Total length of sockaddr */
    u_char  sdl_family; /* AF_DLI */
    u_short sdl_index;  /* if != 0, system given index for interface */
    u_char  sdl_type;   /* interface type */
    u_char  sdl_nlen;   /* interface name length, no trailing 0 reqd. */
    u_char  sdl_alen;   /* link level address length */
    u_char  sdl_slen;   /* link layer selector length */
    char    sdl_data[12];   /* minimum work area, can be larger;
                   contains both if name and ll address */
};

#define LLADDR(s) ((caddr_t)((s)->sdl_data + (s)->sdl_nlen))

#ifndef KERNEL

#include <sys/cdefs.h>

__BEGIN_DECLS
void    link_addr __P((const char *, struct sockaddr_dl *));
char    *link_ntoa __P((const struct sockaddr_dl *));
__END_DECLS

#endif /* !KERNEL */

3.5创建libxti库

cd ../libxti
make

3.6使用客户端程序测试

cd ../intro
make daytimetcpcli
sudo ./daytimetcpsrv		# 一个终端运行服务器样本
./daytimetcpcli 127.0.0.1	# 另一个终端运行客户端样本

客户端运行结果:
UNIX网络编程配置unp.h头文件

4.配置unp.h头文件到处可用

sudo cp unpv13e/lib/unp.h	/usr/include
sudo cp unpv13e/config.h	/usr/include
sudo cp unpv13e/libunp.a	/usr/lib

修改/usr/include下的unp.h头文件中的第7行:
#include “…/config.h” --------------------> #include <config.h>

5.编写程序验证

#include <stdio.h>
#include <unp.h>

int main()
{
	return 0;
}

包含头文件,编译运行没有出错。
