上次通過更換核心實現成功編譯驅動無線網絡卡，但是啟動到系統原核心下依然沒有bcm43142的驅動，遂準備在原核心下編譯驅動，記錄一下 ps：更推薦這種方法，避免因更換核心出現其他相容性問題 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，將原始碼包拷貝至/usr 2.安裝工具 安裝gccyum install -y gcc，如已安裝可跳過 安裝核心對應版本的kernel-headers，kerner-devel，本次使用當前系統映象作為yum源，所以版本也是一致的 [[email protected] ~]# 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.編譯原始碼與安裝驅動 複製原始碼包並解壓 [[email protected] ~]# mkdir -p /usr/local/other/wireless7_2 [[email protected] ~]# cp /usr/hybrid-v35_64-nodebug-pcoem-6_30_223_271.tar.gz /usr/local/other/wireless7_2 [
