Centos&Redhat下bcm43142博通无线网卡linux驱动之二

上次通过更换内核实现成功编译驱动无线网卡，但是启动到系统原内核下依然没有bcm43142的驱动，遂准备在原内核下编译驱动，记录一下 ps：更推荐这种方法，避免因更换内核出现其他兼容性问题 1.准备驱动包 hybrid-v35_64-nodebug-pcoem-6_30_223_271.tar.gz 点我下载 密cmet 下载拷贝进u盘，将源码包拷贝至/usr 2.安装工具 安装gccyum install -y gcc，如已安装可跳过 安装内核对应版本的kernel-headers，kerner-devel，本次使用当前系统镜像作为yum源，所以版本也是一致的 [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.编译源码与安装驱动 复制源码包并解压 [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 编译 [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.
