环境：
操作系统 ： fedora 18
内核版本 ： 3.6.10
网卡 ： Broadcom BCM4312
驱动下载地址： www.broadcom.com/support/802.11/linux_sta.php
问题解决;
1. yum -y install kernel-devel gcc 这两个必须装，要不然会出现错误
2. error: asm/system.h: No such file or directory
2.1 问题描述：
error: asm/system.h: No such file or directory
compilation terminated.
make[2]: *** [/var/hybrid_wl/src/wl/sys/wl_linux.o] Error 1
make[1]: *** [_module_/var/hybrid_wl] Error 2
make[1]: Leaving directory `/usr/src/kernels/3.5.3-1.fc17.x86_64'
make: *** [all] Error 2
2.2 解决方法:
在驱动的解压缩文件夹下查找find ./ -name wl_linux.c
路径为./src/wl/sys/wl_linux.c
# vi wl_linux.c
找到#include <asm/system.h>删除掉这一行
找到.ndo_set_multicast_list 把它改为.ndo_set_rx_mode
退出保存，然后继续 make成功
安装步骤：
先上官网：www.broadcom.com/support/802.11/linux_sta.php下载对应版本的驱动，因为我安装的系统是64位的，我下载了：64-bitdriver 5.100.82.38还要下载补丁：Patchfor compilation problem with kernel versions > 2.6.375.100.82.3。下载后我的到两个文件，分别是：hybrid-portsrc_x86_64-v5_100_82_38.tar.gz和5_100_82_38.patch。我把这两个文件保存在Fedora 15的主目录下。
下面开始安装：
1. 编译内核
先进入下载目录，即我的主目录
#cd /home/dauser
新建目录
#mkdir hybird_wl
# mvhybrid-portsrc_x86_64-v5_100_82_38.tar.gz hybird_wl/
# cdhybird_wl/
# tar xzfhybrid-portsrc_x86_64-v5_100_82_38.tar.gz
# mvhybrid-portsrc_x86_64-v5_100_82_38.tar.gz ../
然后打补丁
#cd /home/dauser
# mv 5_100_82_38.patch hybird_wl/
# cd /home/dauser/hybird_wl
# patch -p0 < 5_100_82_38显示“patchingfile src/wl/sys/wl_linux.c”
# make clean
显示“

然后就简单了
2. 安装内核
#cp wl.ko /lib/modules/`uname -r`/kernel/net/wireless/wl.ko
#cd /lib/modules/`uname -r`/kernel/net/wireless/
# depmod
#modprobe wl
删除其它驱动
#lsmod | grep "b43\|ssb\|wl"显示

重启，看看你的无线网络灯亮了没？呵呵。安装完成！原创，转载请标明
