   1. 安装libnl库

1. 1. 使用命令tar -xvf libnl-1.1.tar.gz解压我们提供的libnl-1.1.tar.gz
   2. 进入libnl-1.1目录下执行./configure --prefix=/usr/local/libnl
   3. 在libnl-1.1/include/netlink-local.h中添加头文件#include
   4. 运行make CC=aarch64-linux-gnu-gcc
   5. 运行make install

1. 1. 编译hostapd

进入wpa_supplicant_8_kk_4.4_rtw_r24640.20171025/hostapd目录下编辑此目录下的.config文件

1. 1. 在.config文件中添加如下内容

LIBNL=/usr/local/libnl

CFLAGS += -I$(LIBNL)/include

LIBS += -L$(LIBNL)/lib

1. 1. 在该hostapd目录下执行make

1. 1. 运行配置

./hostapd rtl_hostapd_5G.conf –B

配置文件rtl_hostapd_5G.conf如下所示。

1. DHCP配置

./hostapd rtl_hostapd_5G.conf -B 正常的话，是可以成功生成AP热点。用电脑和手机可以正常搜到。不过不能分配IP。就是因为没有进行dhcp的原因。

 配置步骤如下。

1. 设置wlan0 ip

   ifconfig wlan0 192.168.2.1

1. 启动wlan0

   ifconfig wlan0 up

1. 新建配置文件

   网上查资料，需要配置文件，才能用udhcpd 工具配置。网上复制一个配置文件，尝试配置，成功了。

   注意配置文件的IP区间是在之前ifconfig wlan0 192.168.2.1 的同一个网段。

   把下面的复制到配置新建的配置文件udhcpd.conf里。把配置文件拷贝到/etc/下。

# Sample udhcpd configuration file (/etc/udhcpd.conf)

# The start and end of the IP lease block

start       192.168.2.2 #default: 192.168.0.20

end     192.168.2.254   #default: 192.168.0.254

# The interface that udhcpd will use

interface   wlan0       #default: eth0

# The maximim number of leases (includes addressesd reserved

# by OFFER's, DECLINE's, and ARP conficts

max_leases  253     #default: 254

# If remaining is true (default), udhcpd will store the time

# remaining for each lease in the udhcpd leases file. This is

# for embedded systems that cannot keep time between reboots.

# If you set remaining to no, the absolute time that the lease

# expires at will be stored in the dhcpd.leases file.

remaining   yes     #default: yes

# The time period at which udhcpd will write out a dhcpd.leases

# file. If this is 0, udhcpd will never automatically write a

# lease file. (specified in seconds)

auto_time   7200        #default: 7200 (2 hours)

# The amount of time that an IP will be reserved (leased) for if a

# DHCP decline message is received (seconds).

decline_time    3600        #default: 3600 (1 hour)

# The amount of time that an IP will be reserved (leased) for if an

# ARP conflct occurs. (seconds

conflict_time   3600        #default: 3600 (1 hour)

# How long an offered address is reserved (leased) in seconds

offer_time  60      #default: 60 (1 minute)

# If a lease to be given is below this value, the full lease time is

# instead used (seconds).

min_lease   60      #defult: 60

# The location of the leases file

lease_file  /var/lib/misc/udhcpd.leases #defualt: /var/lib/misc/udhcpd.leases

# The location of the pid file

pidfile /var/run/udhcpd-wlan2.pid   #default: /var/run/udhcpd.pid

# Every time udhcpd writes a leases file, the below script will be called.

# Useful for writing the lease file to flash every few hours.

#notify_file                #default: (no script)

#notify_file    dumpleases  # <--- useful for debugging

# The following are bootp specific options, setable by udhcpd.

#siaddr     192.168.0.22        #default: 0.0.0.0

#sname      zorak           #default: (none)

#boot_file  /var/nfs_root       #default: (none)

# The remainer of options are DHCP options and can be specifed with the

# keyword 'opt' or 'option'. If an option can take multiple items, such

# as the dns option, they can be listed on the same line, or multiple

# lines. The only option with a default is 'lease'.

#Examles

opt dns 114.114.114.114 #192.168.2.1

option  subnet  255.255.255.0

option  domain  local   #atherosowl.com

option  lease   864000      # 10 days of seconds

# Currently supported options, for more info, see options.c

#static_lease 00:60:08:11:CE:3E 192.168.0.44

1. 运行配置命令

先ps看一下后台有没有udhcpd和hostapd程序在执行

有的话就killall udhcpd 或者 killall hostapd给关掉

Udhcpd udhcpd.conf

或者

udhcpd -fS /etc/udhcpd.conf &

hostapd -B /etc/hostapd.conf

执行这两个程序，可能udhcpd会报如下的错误，在相应目录新建一个对应名字文件即可

root@ti81xx:~# udhcpd (v1.19.4) started

udhcpd: can't open '/var/lib/misc/udhcpd.leases': No such file or directory

到这一步，就可以用电脑连接模块生成的AP了。并且可以自动获取IP了。可以ping通板子，也可以通过ssh远程连接板子了。
