买了树莓派2，正好原来有 360wifi2 ，不幸的是树莓派2不能直接支持，需要自己编译相关驱动，在网上搜索了不少教程，发现大多数是针对树莓派1的，就算有些是树莓派2的，也写得不是很清楚，所以就把整个编译过程记录下来，希望能对有相同需求的朋友增加一点帮助，因为有些细节对于新手很容易出错，所以本文尽量详细，不厌其烦，不做省略，把所有的操作步骤都记录下来，如果显示内容太多，但大多是些不必要知道的信息，就用 …… 表示。

写在最前面需要注意的事项：Linux软件版本很重要，往往同样一个项目，内核版本升级或者gcc版本升级都可能导致编译不通过，或者就算编译通过了运行起来也不稳定。

所以，所有打算参考本文进行操作的朋友，请务必保证你的程序、编译器、系统版本跟本文的一致！

系统版本：

pi@raspberrypi /opt/github/mt7601u-ap $ uname -r

4.1.6-v7+

pi @raspberrypi /opt/github/mt7601u-ap $ uname -a

Linux raspberrypi 4.1.6-v7+ #810 SMP PREEMPT Tue Aug 18 15:32:12 BST 2015 armv7l GNU/Linux

内核编译版本：

pi @raspberrypi /opt/github/mt7601u-ap $ cat /proc/version
Linux version 4.1.6-v7+ (dc4@dc4-XPS13-9333) (gcc version 4.8.3 20140303 (prerelease) (crosstool-NG linaro-1.13.1+bzr2650 - Linaro GCC 2014.03) ) #810 SMP PREEMPT Tue Aug 18 15:32:12 BST 2015

pi @raspberrypi /opt/github/mt7601u-ap $

编译器版本：

pi@raspberrypi /opt/github/mt7601u-ap $ gcc --version

驱动版本：

pi@raspberrypi /opt/github/mt7601u-ap $ git remote -v
origin https://github.com/eywalink/mt7601u (fetch)
origin https://github.com/eywalink/mt7601u (push)

pi@raspberrypi /opt/github/mt7601u-ap $

（这个版本据使用者说可以支持ap，不过我还没来得及试验）

整个编译过程分两部分：

第一部分是操作系统更新，包括更新树莓派固件，下载Linux内核源码，建立内核模块库目录的符号链接；

第二部分是下载360wifi2的Linux驱动代码，我下载的驱动文件已经添加对360wifi2（MT7601）的支持，不需要大家手动添加了，到时候直接编译就行。最后再以内核模块的形式对已经编译好的无线网卡驱动模块进行安装。

正如某位同学所说，因为 MT7601 比较便宜，所以有不少设备商使用了它，比如小度wifi，小米wifi，腾讯wifi什么的，对这些网卡的支持也已经加入驱动代码，具体修改的地方如下：

在下载了的驱动源码包里的文件 src/common/rtusb_dev_id.c 里面，加入如下内容：

在 {USB_DEVICE(0x148f,0×7601)}, /* MT 6370 */ 下面加入以下内容：

{USB_DEVICE(0x148f,0x760b)}, /* 360 Wifi */

{USB_DEVICE(0x2955,0x1001)}, /* baidu Wifi */

{USB_DEVICE(0x2a5f,0x1000)}, /* Tencent WIFI */

{USB_DEVICE(0×2955,0×0001)}, /* XiaoDu Wifi */

{USB_DEVICE(0x2717,0x4106)}, /* Xiaomi Wifi */

下面开始正式的编译过程：

第一部分：

1、首先是更新 rpi 固件，执行 rpi-update，记录如下：

我最初参照此文（ http://www.7forz.com/2470/）编译过一次，内核用 gcc-4.6 编译，无线网卡驱动用 gcc-4.8 编译，虽然可以正常上网，但是使用一段时间后有可能随机出现 oop 死机，错误信息如下：

pi@raspberrypi /opt/github $
Message from syslogd@raspberrypi at Aug 20 12:56:15 ... "raspberrypi" 12:56 20-Aug-15

kernel:[50382.924472] Internal error: Oops: 8000000d [#1] PREEMPT SMP ARM

因为我用树莓派2做服务器的一个目标就是追求稳定可靠，当然不能接受随机性死机，所以这个问题必须解决。

（补充：写到最后才发现出错的原因可能有两个：一个是我的gcc版本是 4.8.2，而要求版本是 4.8.3 以上；一个是使用了 ARMv6 的 Module.symvers 文件，应该使用对应于ARMv7 的Module7.symvers）

最初决定参照此文（ http://www.freemindworld.com/blog/2015/150312_complie_kernel_module_for_raspberry_pi_2.shtml），自己手动安装,把内核和网卡驱动模块重新全部在 gcc-4.8 下编译一遍。

查看一下当前的 gcc

执行记录如下：

pi@raspberrypi ~ $ ls -al /usr/bin/gcc*

更新内核模块，使用以下命令：

sudo apt - get update

sudo apt-get upgrade

sudo apt-get dist-upgrade

sudo rpi-update

pi@raspberrypi ~ $

最后提示这时需要重启来激活新固件

重启前后使用如下命令检查当前系统内核版本号：

uname -a

uname -r

执行记录如下：

重启前查询：

pi@raspberrypi ~ $ uname -a

Linux raspberrypi 4.1.5-v7+ #809 SMP PREEMPT Thu Aug 13 00:50:56 BST 2015 armv7l GNU/Linux

pi@raspberrypi ~ $ uname -r
4.1.5-v7+

pi@raspberrypi ~ $

重启后查询：

pi@raspberrypi /opt/software $ uname -a
Linux raspberrypi 4.1.6-v7+ #810 SMP PREEMPT Tue Aug 18 15:32:12 BST 2015 armv7l GNU/Linux
pi@raspberrypi /opt/software $ uname -r
4.1.6-v7+

pi@raspberrypi /opt/software $

发现我们的固件版本号已经从原来的 4.1.5 更新到了最新的 4.1.6

接着使用如下命令取得对应版本的内核代码，这个操作执行起来要花点时间，耐心等待吧。

sudo wget https://github.com/raspberrypi/linux/archive/rpi-4.1.y.tar.gz

执行记录如下：

pi@raspberrypi /opt/software $

接着执行如下命令，先切换到 root（后续的命令就不需要再加 sudo 了，提示符也由 $ 变为 #），然后移动目录到 /usr/src

sudo su

mv ./linux-rpi-/ /usr/src/

记录如下：

pi@raspberrypi /opt/software $ sudo su
root@raspberrypi:/opt/software# mv ./linux-rpi-4.1.y/ /usr/src

root@raspberrypi:/opt/software#

执行如下命令，建立软连接（注意，这里必须是全部路径，而且不可以缺少 “/”，否则会在 /lib/下新建一个名为的目录，这个地方容易被疏忽，编译时会导致无法找到而出错）

ln -s /usr/src/linux-rpi-4.1.y/ /lib/modules/4.1.6-v7+/build

记录如下：

root@raspberrypi:/opt/software# ln -s /usr/src/linux-rpi-4.1.y/ /lib/modules/4.1.6-v7+/build

root@raspberrypi:/opt/software#

进入该 build 目录，执行如下命令清除一下编译环境：

make mrproper

执行记录如下：

root@raspberrypi:/opt/software# cd /lib/modules/4.1.6-v7+/build
root@raspberrypi:/lib/modules/4.1.6-v7+/build# ls

root@raspberrypi:/lib/modules/4.1.6-v7+/build#

执行如下命令，在 /proc 目录下生成 config.gz 文件，这个命令在树莓派1是不需要执行的，但是树莓派2必须执行：

modprobe configs

执行记录如下：

接着执行如下命令，把 config.gz 导出到 /build 目录下，名为 .config

gzip -dc /proc/config.gz > .config

非常不幸地出现这个错误：#error Your compiler is too buggy; it is known to miscompile kernels，根据后面的报错提示，应该是 /proc/version 是 gcc-4.8.3，而我当前安装的是 gcc-4.8.2，所以改变手动安装策略，干脆使用 dpi-source 来自动安装

很明显，这个脚本比较错了，在 /proc/version 下取版本号把 Linux 的版本号给取了，而没有取 gcc 的版本号，看了下 gthub 上已经有人提这个bug了，作者也改了，但是很明显，修改无效。

不过先看看我的 gcc 版本，打开这篇文档（ https://github.com/notro/rpi-source/wiki），发现要把 gcc 版本升到 4.8.3，但是我目前的 gcc 版本是 4.8.2，官方源最新版本就是 4.8.2，于是按照该文的提示，做了如下操作：

增加目前处于测试状态的更新源 jessie，打开文件

sudo nano /etc/apt/sources.list.d/jessie.list，

增加一句

deb http://mirrordirector.raspbian.org/raspbian/ jessie main contrib non-free rpi

保存退出

再次更新：

sudo apt-get update

执行记录如下

显然，版本比较的错误还是会影响编译，不过我对脚本不是很熟悉，不太会修改，于是再次换回原来的手工操作，因为已经把 gcc 的版本升级了，理论上可以编译通过，事实果然如此，

接下来取得模块符号，这里对于树莓派1和树莓派2是有区别的，因为1使用的是ARMv6，2使用的是ARMv7，它们对应的文件分别是：

树莓派1： https://github.com/raspberrypi/firmware/blob/master/extra/Module.symvers

树莓派2： https://github.com/raspberrypi/firmware/blob/master/extra/Module7.symvers

不过取回来之后需要改名为 Module.symvers 保存在 build 目录下

好了，到目前为止，终于千辛万苦地完成了第一阶段的工作，也就是无线模块编译的准备工作。

第二部分：

接下来要开始正式编译无线模块了，这次我选择了一个据说能支持 AP 功能的驱动，虽然是1年前的

git clone https://github.com/eywalink/mt7601u mt7601u-ap

进入该目录，查看一下，发现有一个 build.sh 的脚本，看看内容：

root@raspberrypi:/opt/github/mt7601u-ap# ls
build.sh doc HISTORY LICENSE Makefile Makefile.inc miwifi_work.sh README.md unload.sh

很好，直接运行 build.sh 貌似就可以了，

执行记录如下：

看来暂时是 OK 了

先进入目录 /opt/github/mt7601u-ap/src/os/linux/ 查看一下我们编译出来的驱动是什么样子

执行记录如下：

pi@raspberrypi /opt/github/mt7601u-ap/src/os/linux $ ls -al *.ko
-rw-r--r-- 1 root root 1373192 Aug 21 15:56 mt7601Uap.ko
-rw-r--r-- 1 root root 27516 Aug 21 15:56 rtnet7601Uap.ko
-rw-r--r-- 1 root root 109552 Aug 21 15:52 rtutil7601Uap.ko

pi@raspberrypi /opt/github/mt7601u-ap/src/os/linux $

再用 wicd-curses 看看

执行记录如下：

看来目前为止是可以正常搜索到wifi信号了。

如果希望手动安装/卸载我们编译出来的驱动，可以在本目录（/opt/github/mt7601u-ap/src/）下执行：

sudo su

make install

make uninstall

执行记录如下：

至于 AP 的设置，我还没有弄，要试验的话打算参照这篇文档：[【L】小米随身WiFi，Linux下AP热点驱动（开源）] ( http://blog.csdn.net/sumang_87/article/details/38168877)

再编译一个看起来不支持 ap 版本的（不过好像也支持）

手动安装/卸载的方法同上。

以上就是今天花费大半天时间的工作记录，应该也是目前最新的关于树莓派2下编译360wifi2的教程，希望能对正在折腾树莓派2的朋友有所帮助。
