在Visual Studio 2012下编译lwip-2.1.3 httpd的makefsdata

步骤一 建立空白工程

新建一个工程,项目名称起名为makefsdata。
因为mkfsdata是一个控制台程序,所以我们要选择Win32 Console Application。

这里很重要,必须要勾选“Empty Project”选项,建立空项目:

建好的解决方案目录是C:\Users\Octopus\Desktop\makefsdata,工程目录是C:\Users\Octopus\Desktop\makefsdata\makefsdata。

步骤二 解压lwip-2.1.3的部分头文件和源文件

去官网下载lwip-2.1.3.zip,解压下列文件到工程目录
lwip-2.1.3.zip\lwip-2.1.3\src\include ---> 工程目录\lwip-2.1.3\include(解压整个文件夹,以及所有文件)
lwip-2.1.3.zip\lwip-2.1.3\src\core\def.c ---> 工程目录\lwip-2.1.3\core\def.c
lwip-2.1.3.zip\lwip-2.1.3\src\core\inet_chksum.c ---> 工程目录\lwip-2.1.3\core\inet_chksum.c
lwip-2.1.3.zip\lwip-2.1.3\src\apps\http\mkfsdata ---> 工程目录\lwip-2.1.3\apps\http\mkfsdata(整个文件夹)
lwip-2.1.3.zip\lwip-2.1.3\src\apps\http\httpd_structs.h ---> 工程目录\lwip-2.1.3\apps\http\httpd_structs.h

步骤三 建立配置文件

建立“工程目录\lwip-2.1.3\include\arch\cc.h”,内容如下:
这里涉及到一个很重要的知识点:如何在Visual Studio下定义__packed关键字。

#ifndef LWIP_ARCH_CC_H
#define LWIP_ARCH_CC_H

#define LWIP_RAND() ((u32_t)rand())
#define PACK_STRUCT_BEGIN __pragma(pack(push, 1))
#define PACK_STRUCT_END __pragma(pack(pop))

#pragma warning(disable:4996) // 允许使用strcpy等不带_s后缀的函数
#define snprintf _snprintf

#endif

建立“工程目录\lwip-2.1.3\include\lwipopts.h”,内容如下:

#ifndef LWIP_LWIPOPTS_H
#define LWIP_LWIPOPTS_H

#define NO_SYS 1 // 无操作系统
#define SYS_LIGHTWEIGHT_PROT 0 // 不进行临界区保护

#define LWIP_NETCONN 0
#define LWIP_SOCKET 0

#define MEM_ALIGNMENT 4 // STM32单片机是32位的单片机, 因此是4字节对齐的
#define MEM_SIZE 10240 // lwip的mem_malloc函数使用的堆内存的大小

// 配置TCP
#define TCP_MSS 1500
#define LWIP_TCP_SACK_OUT 1 // 允许选择性确认

// 配置DHCP
#define LWIP_DHCP 1
#define LWIP_NETIF_HOSTNAME 1

// 配置DNS
#define LWIP_DNS 1

// 广播包过滤器
// 如果打开了这个过滤器, 那么就需要在套接字上设置SOF_BROADCAST选项才能收发广播数据包
//#define IP_SOF_BROADCAST 1
//#define IP_SOF_BROADCAST_RECV 1

// 配置IPv6
#define LWIP_IPV6 1
#define LWIP_ND6_RDNSS_MAX_DNS_SERVERS LWIP_DNS // 允许SLAAC获取DNS服务器的地址

#endif

建立“工程目录\lwip-2.1.3\include\inttypes.h”,内容如下:

步骤四 将文件添加到Visual Studio 2012工程中

工程中只添加mkfsdata.c文件,其余的文件一律不添加

在Visual Studio 2012下编译lwip-2.1.3 httpd的makefsdata_第5张图片

步骤五 编译生成32位Release版程序

要求:生成的程序能够在刚安装好的纯净版Windows XP系统上直接运行,不需要安装任何运行时库。

首先切换到Release模式:

打开项目属性:

在Visual Studio 2012下编译lwip-2.1.3 httpd的makefsdata_第7张图片

选择Visual Studio 2012 - Windows XP (v110_xp)模式:

在Visual Studio 2012下编译lwip-2.1.3 httpd的makefsdata_第8张图片

添加lwip-2.1.3的头文件路径:

选择多线程模式(/MT),不依赖于任何Runtime库的DLL。

编译程序:

1>------ Build started: Project: makefsdata, Configuration: Release Win32 ------
1>  makefsdata.c
1>  Generating code
1>  Finished generating code
1>  makefsdata.vcxproj -> C:\Users\Octopus\Desktop\makefsdata\Release\makefsdata.exe
========== Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========

程序就编译出来了。把这个程序放到单片机lwip工程的apps/http文件夹下就可以用了。
程序的功能是把fs文件夹下的所有网页和图片文件,整合成一个fsdata.c文件。
