无网络状态下CentOS无线网卡驱动安装

表示没事就瞎整某些东西，把CentOS装到硬盘后就开始烦恼无线网卡驱动的安装。
先说一下我的环境：
1.有有线网卡驱动
2.处于校园网，上网需要认证（H3C iNode什么的）
3.无线网卡驱动没有
4.无线网卡型号为Broadcom Corp BCM43142A0
5.Windows环境下可以上网
一开始，我在windows上把驱动下好，把教程web页面保存下来，都放FAT32的分区里。
重启进去挂上分区才发现 CentOS 没有gcc。
（太坑了！！）
然后我又把gcc的源码包放进去，重启又发现gcc编译需要另外的编译器（？完全不明白这种依赖关系是为啥）
就这样各种下依赖包，挂分区失败中度过了3天。
然后我最后才醒悟，我完全可以用虚拟机安装然后copy安装包到实体机中啊！(之前功夫都白做了)
yum的配置文件位于/etc/yum.conf
由于我们需要安装包所以将里面的
在终端执行
3.复制安装包
yum的缓存地址为\var\cache\yum
在底下的文件夹找到刚刚终端显示的那几个rpm安装包就行了，复制出虚拟机。
4.在实体机上安装
按照在虚拟机上的安装顺序安装rpm包就行了。
需要修改源码
所以第一步：
1.修改源码
这里我放上我自己修改的wl_cfg80211_hybrid.c（位于解压路径下的/src/wl/sys/）
大部分修改都是注释掉一些东西
2.编译
执行
之后编译过程中在linux.c中还出现了几个警告，不过我不会改，所以就忽视了。
3.安装
最后，总算顺利的安装好了，上网也没有问题了

下面是gcc在离线状态下的安装过程
1.重新设置yum配置文件yum的配置文件位于/etc/yum.conf
由于我们需要安装包所以将里面的
keepcache = 0修改为
keepcache = 12.安装gcc
在终端执行
yum install gcc等待安装完成(注意：应当记录下各个安装包的安装顺序)
3.复制安装包
yum的缓存地址为\var\cache\yum
在底下的文件夹找到刚刚终端显示的那几个rpm安装包就行了，复制出虚拟机。
4.在实体机上安装
按照在虚拟机上的安装顺序安装rpm包就行了。
然后是网卡的编译与安装
有一点需要特别注意的就是官方的Broadcom驱动其实有问题需要修改源码
所以第一步：
1.修改源码
这里我放上我自己修改的wl_cfg80211_hybrid.c（位于解压路径下的/src/wl/sys/）

#endif 2.编译
执行
make API=CFG80211此处不能用WEXT,README里说已经被其废弃了，即使编译成功也会出现无法连接的问题
之后编译过程中在linux.c中还出现了几个警告，不过我不会改，所以就忽视了。
3.安装
最后，总算顺利的安装好了，上网也没有问题了
