2. 配置修改,编译
#cp defconfig .config
#vi .config
增加这几行
CFLAGS += -I/usr/local/ssl/include
LIBS += -L/usr/local/ssl/lib
CC = arm-hismall-linux-gcc -L /usr/local/ssl/lib/
#make
需要先编译安装openssl库，确保两个编译都使用统一工具arm-hismall-linux-gcc
不一致会出现这样的问题:
/usr/bin/ld: skipping incompatible /usr/local/ssl/lib/libssl.so when searching for -lssl
/usr/bin/ld: skipping incompatible /usr/local/ssl/lib/libssl.a when searching for -lssl
/usr/bin/ld: cannot find -lssl
/usr/bin/ld: skipping incompatible /usr/local/ssl/lib/libcrypto.so when searching for -lcrypto
/usr/bin/ld: skipping incompatible /usr/local/ssl/lib/libcrypto.a when searching for -lcrypto
/usr/bin/ld: cannot find -lcrypto
collect2: ld returned 1 exit status
make: *** [wpa_supplicant] Error 1
这样只要把openssl和wpa_supplicant两个用同一个编译工具编译即可。
3. 产品板使用：
3.1. 把wpa_supplicant.conf拷贝到/xxx目录下 (xxx目录自定)
按加密方式分3种，以下3个配置文件均测试正常
# 无密码 wpa_supplicant.conf内容：
ctrl_interface=/var/run/wpa_supplicant
network={
ssid="XXXXXX"
key_mgmt=NONE
}
# WEP密码 wpa_supplicant.conf内容：
ctrl_interface=/var/run/wpa_supplicant
network={
ssid="XXXXXX"
key_mgmt=NONE
wep_key0="XXXXXX"
wep_tx_keyidx = 0
}
# WPA密码 wpa_supplicant.conf内容：
# WPA-PSK/TKIP
ctrl_interface=/var/run/wpa_supplicant
network=
{
ssid="XXXXXX"
ap_scan=1;
key_mgmt=WPA-EAP WPA-PSK IEEE8021X NONE
pairwise=TKIP CCMP
group=CCMP TKIP WEP104 WEP40
psk="XXXXXX"
}
3.2. wpa_supplicant拷贝到/xxx/目录下
//无桥方式
wpa_supplicant -B -ira0 -c /xxx/wpa_supplicant.conf -Dwext (xxx为前面wpa_supplicant.conf目录)
//有桥接方式（bridge-utils）
wpa_supplicant -B -b br0 -ira0 -c /xxx/wpa_supplicant.conf -Dwext
如果运行时出现：
socket(PF_PACKET): Address family not supported by protocol
原因
内核不支持RAW socket，编译内核时把CONFIG_PACKET选项打开，
CONFIG_PACKET = y
If we use CONFIG_PACKET=m instead of CONFIG_PACKET=y we'd need to
include af_packet.ko into the initramfs for netboot installation.
手动加载af_packet.ko
#insmod af_packet.ko
显示
NET: Registered protocol family 17
加载正常
3.3 运行#wpa_supplicant
#wpa_supplicant -B -ira0 -c /xxx/wpa_supplicant.conf -Dwext

设置完一会，等网络连接好就可以了。
