ixp425开发板下移植hostapd做虚拟ap环境

ap 环境搭建

 

一． 需求

ixp425 开发板， hostapd       madwifi

二． 实验原理

madwifi 网卡驱动， hostapd 是认证软件

三． 操作流程

a)         移植 madwifi

make KERNELPATH= /root/linux-2.6.x/ CROSS_COMPILE = arm-linux-

b)        移植 hostapd

                         i.              修改 .config

设置 hostapd 功能（只做 ap ）

                                          # Driver interface for madwifi driver
CONFIG_DRIVER_MADWIFI=y
CFLAGS += -I/root/madwifi-0.9.4 # change to the madwifi source directory

 

 

                       ii.              修改交叉编译

Makefile 中

加入

CC=/arm/linux/ixp425/snapgear/tools/ucfront-gcc   (  中间一个空格 )

 /usr/local/arm/ 3.4.4 /bin/arm-linux-gcc

make: *** [hostapd.o] 错误 1

个人分析，问题有三大类，

1，一些数据结构未定义，

2，一些类型名出现语法错误，是头文件未编译的结果

3，宏定义

 

                                                  

四.     实验中问题及解决方法

a)         问题： madwifi 无法被指定内核编译

解决办法： make 时加上相应参数

原因：在读 INSTALL 时不够细心

b)        问题：交叉编译 hostapd 时无法使用指定交叉编译工具编译，总是使用 gcc 编译

解决办法：在 Makefile 文件中，自己加上 CC= 。。。。。。

原因： Makefile 不熟悉

遗留问题：在没有其他定义 CC 时，从 ifndef CC 中设定 CC 路径， CC 赋值语句无效，自己在 ifndef CC 外部设定 CC 路径，可以生效。不解。

c）    问题：使用 ucfront-gcc arm-linux-gcc 编译出错，现象如图三 .b （未解决）

解决思路：判断是交叉编译问题还是 Makefile 问题，实验只使用 arm-linux-gcc 编译，没有错误，架构为 arm 架构，说明 arm-linux-gcc 部分没有问题
