Centos&Redhat下bcm43142博通無線網卡linux驅動之二

上次經過更換內核實現成功編譯驅動無線網卡，可是啓動到系統原內核下依然沒有bcm43142的驅動，遂準備在原內核下編譯驅動，記錄一下

ps：更推薦這種方法，避免因更換內核出現其餘兼容性問題

1.準備驅動包

hybrid-v35_64-nodebug-pcoem-6_30_223_271.tar.gz
點我下載 密cmet
下載拷貝進u盤，將源碼包拷貝至/usr

2.安裝工具

安裝gccyum install -y gcc，如已安裝可跳過
安裝內核對應版本的kernel-headers，kerner-devel，本次使用當前系統鏡像做爲yum源，因此版本也是一致的

[root@king ~]# yum list|grep kernel
 kernel.x86_64                           3.10.0-327.el7             @anaconda/7.2
 kernel-devel.x86_64                     3.10.0-327.el7             @rhel7.2_iso 
 kernel-headers.x86_64                   3.10.0-327.el7             @rhel7.2_iso

3.編譯源碼與安裝驅動

複製源碼包並解壓

[root@king ~]# mkdir -p /usr/local/other/wireless7_2
 [root@king ~]# cp /usr/hybrid-v35_64-nodebug-pcoem-6_30_223_271.tar.gz /usr/local/other/wireless7_2
 [root@king ~]# cd /usr/local/other/wireless7_2
 [root@king wireless7_2]# tar zxf hybrid-v35_64-nodebug-pcoem-6_30_223_271.tar.gz
 [root@king wireless7_2]# ls
 hybrid-v35_64-nodebug-pcoem-6_30_223_271.tar.gz  lib  Makefile  src

編譯

[root@king wireless7_2]# make
 KBUILD_NOPEDANTIC=1 make -C /lib/modules/`uname -r`/build M=`pwd`
 make: *** /lib/modules/3.10.0-327.el7.x86_64/build: No such file or directory.  Stop.
 make: *** [all] Error 2

報錯，分析錯誤緣由，發現/lib/modules/3.10.0-327.el7.x86_64/build軟連接失效，重作之

ln -s /usr/src/kernels/3.10.0-327.el7.x86_64/ /lib/modules/3.10.0-327.el7.x86_64/build  #注意作軟連接要寫絕對路徑

發現報錯，依次排錯
由報錯信息知wl_cfg80211_hybrid.c文件第1460，1477，1894，2037，2124行有錯，作出以下更改

[root@king wireless7_2]# vim src/wl/sys/wl_cfg80211_hybrid.c
 1460 //              sinfo->filled |= STATION_INFO_TX_BITRATE;

 1894         wdev->wiphy->wowlan = &wl_wowlan_support;
 2035         cbss = cfg80211_inform_bss(wiphy, channel, CFG80211_BSS_FTYPE_UNKNOWN, (const u8 *)(bi->BSSID.octet),
 2036                 0, beacon_proberesp->capab_info, beacon_proberesp->beacon_int,
 2037                 (const u8 *)notify_ie, notify_ielen, signal, GFP_KERNEL);

tips：vim裏按冒號輸入set nu顯示行號，冒號後接行號定位到該行

發現已生成驅動文件wl.ko

安裝驅動文件

[root@king wireless7_2]# make install
 install -D -m 755 wl.ko /lib/modules/`uname -r`/kernel/drivers/net/wireless

4.驅動文件加載和配置

加載驅動文件

[root@king wireless7_2]# insmod wl.ko
 [root@king wireless7_2]# lsmod|grep wl
 wl                   6445574  0 
 cfg80211              572836  1 wl

發現右上角出現wifi選項，驅動加載成功，能夠鏈接wifi啦，Enjoying it！
