基於2015-0505-Raspbian 鏡像的樹莓派2用gcc4.8 編譯 360wifi2 過程
目錄
介紹
買了樹莓派2，正好原來有 360wifi2 ，不幸的是樹莓派2不能直接支持，須要本身編譯相關驅動，在網上搜索了很多教程，發現大多數是針對樹莓派1的，就算有些是樹莓派2的，也寫得不是很清楚，因此就把整個編譯過程記錄下來，但願能對有相同需求的朋友增長一點幫助，由於有些細節對於新手很容易出錯，因此本文儘可能詳細，不厭其煩，不作省略，把全部的操做步驟都記錄下來，若是顯示內容太多，但大可能是些沒必要要知道的信息，就用 …… 表示。php
注意事項
寫在最前面須要注意的事項：Linux軟件版本很重要，每每一樣一個項目，內核版本升級或者gcc版本升級均可能致使編譯不經過，或者就算編譯經過了運行起來也不穩定。html
因此，全部打算參考本文進行操做的朋友，請務必保證你的程序、編譯器、系統版本跟本文的一致！linux
系統版本：
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
內核編譯版本：
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 $
編譯器版本：
pi@raspberrypi /opt/github/mt7601u-ap $ gcc --version gcc (Raspbian 4.8.4-1) 4.8.4 Copyright (C) 2013 Free Software Foundation, Inc. This is free software; see the source for copying conditions.

驅動版本：
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 $ （這個版本據使用者說能夠支持ap，不過我還沒來得及試驗）
整個編譯過程分兩部分： 第一部分是操做系統更新，包括更新樹莓派固件，下載Linux內核源碼，創建內核模塊庫目錄的符號連接； 第二部分是下載360wifi2的Linux驅動代碼，我下載的驅動文件已經添加對360wifi2（MT7601）的支持，不須要你們手動添加了，到時候直接編譯就行。最後再之內核模塊的形式對已經編譯好的無線網卡驅動模塊進行安裝。ios
正如某位同窗所說，由於 MT7601 比較便宜，因此有很多設備商使用了它，好比小度wifi，小米wifi，騰訊wifi什麼的，對這些網卡的支持也已經加入驅動代碼， 具體修改的地方以下： 在下載了的驅動源碼包裏的文件 src/common/rtusb_dev_id.c 裏面，加入以下內容： 在 {USB_DEVICE(0x148f,0×7601)}, /* MT 6370 */ 下面加入如下內容：c++
{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 */
下面開始正式的編譯過程：git
第一部分：固件更新+內核模塊編譯準備
一、首先是更新 rpi 固件，執行 rpi-update，記錄以下：github
我最初參照此文（http://www.7forz.com/2470/）編譯過一次，內核用 gcc-4.6 編譯，無線網卡驅動用 gcc-4.8 編譯，雖然能夠正常上網，可是使用一段時間後有可能隨機出現 oop 死機，錯誤信息以下：web
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
由於我用樹莓派2作服務器的一個目標就是追求穩定可靠，固然不能接受隨機性死機，因此這個問題必須解決。 （補充：寫到最後才發現出錯的緣由可能有兩個：一個是個人gcc版本是 4.8.2，而要求版本是 4.8.3 以上；一個是使用了 ARMv6 的 Module.symvers 文件，應該使用對應於ARMv7 的Module7.symvers）apache
最初決定參照此文（http://www.freemindworld.com/blog/2015/150312_complie_kernel_module_for_raspberry_pi_2.shtml），本身手動安裝,把內核和網卡驅動模塊從新所有在 gcc-4.8 下編譯一遍。c#
查看一下當前的 gcc

最後提示這時須要重啓來激活新固件 重啓先後使用以下命令檢查當前系統內核版本號：
uname -a uname -r
執行記錄以下： 重啓前查詢：
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 ~ $
重啓後查詢：
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 $
發現咱們的固件版本號已經從原來的 4.1.5 更新到了最新的 4.1.6
接着使用以下命令取得對應版本的內核代碼，這個操做執行起來要花點時間，耐心等待吧。

接着執行以下命令，先切換到 root（後續的命令就不須要再加 sudo 了，提示符也由 $ 變爲 #），而後移動目錄到 /usr/src
sudo su mv ./linux-rpi-/ /usr/src/
執行記錄以下：
pi@raspberrypi /opt/software $ sudo su root@raspberrypi:/opt/software# mv ./linux-rpi-4.1.y/ /usr/src root@raspberrypi:/opt/software#
執行以下命令，創建軟鏈接（注意，這裏必須是所有路徑，並且不能夠缺乏 「/」，不然會在 /lib/下新建一個名爲 的目錄，這個地方容易被疏忽，編譯時會致使沒法找到而出錯）
ln -s /usr/src/linux-rpi-4.1.y/ /lib/modules/4.1.6-v7+/build
執行記錄以下：
root@raspberrypi:/opt/software# ln -s /usr/src/linux-rpi-4.1.y/ /lib/modules/4.1.6-v7+/build root@raspberrypi:/opt/software#
進入該 build 目錄，執行以下命令清除一下編譯環境：
make mrproper

執行以下命令，在 /proc 目錄下生成 config.gz 文件，這個命令在樹莓派1是不須要執行的，可是樹莓派2必須執行：
modprobe configs
執行記錄以下：

很明顯，這個腳本比較錯了，在 /proc/version 下取版本號把 Linux 的版本號給取了，而沒有取 gcc 的版本號，看了下 gthub 上已經有人提這個bug了，做者也改了，可是很明顯，修改無效。
不過先看看個人 gcc 版本，打開這篇文檔（https://github.com/notro/rpi-source/wiki），發現要把 gcc 版本升到 4.8.3，可是我目前的 gcc 版本是 4.8.2，官方源最新版本就是 4.8.2，因而按照該文的提示，作了以下操做：
增長目前處於測試狀態的更新源 jessie，打開文件
sudo nano /etc/apt/sources.list.d/jessie.list，
增長一句

保存退出

顯然，版本比較的錯誤仍是會影響編譯，不過我對腳本不是很熟悉，不太會修改，因而再次換回原來的手工操做，由於已經把 gcc 的版本升級了，理論上能夠編譯經過，事實果真如此，

好了，到目前爲止，終於千辛萬苦地完成了第一階段的工做，也就是無線模塊編譯的準備工做。

接下來要開始正式編譯無線模塊了，此次我選擇了一個聽說能支持 AP 功能的驅動，雖然是1年前的
git clone https://github.com/eywalink/mt7601u mt7601u-ap
進入該目錄，查看一下，發現有一個 build.sh 的腳本，看看內容：

至於 AP 的設置，我尚未弄，要試驗的話打算參照這篇文檔：[【L】小米隨身WiFi，Linux下AP熱點驅動（開源）] (http://blog.csdn.net/sumang_87/article/details/38168877)
再編譯一個看起來不支持 ap 版本的 （好像聽說也支持，不過我沒試過）

手動安裝/卸載的方法同上。
以上就是今天花費大半天時間的工做記錄，應該也是目前最新的關於樹莓派2下編譯360wifi2的教程，但願能對正在折騰樹莓派2的朋友有所幫助。
補充：360wifi2目前已經穩定鏈接一夜+一上午，還沒用出現 oops 崩潰，目前看來還比較穩定。
