android4.1.1係統編譯全過程

一、編譯環境：

首先介紹編譯中使用的工具：

虛擬機： vmare 9 下載地址：https://blog.csdn.net/hudan2714/article/details/7902654

linux平台：ubuntu 12.04 64位

jdk: sun-java6-jdk （64位）

交叉編譯工具鏈：gcc 使用的版本是：4.6.3

想要完成最終的編譯，當然首要的就是檢查環境：

1、安裝的ubuntu設置空間大小：至少需要30G

目前下載的包就有10G：有圖有真相：

包括解壓編譯後大小有30G了：

所以空間一定要夠了才行。

2、gcc和g++不能使用使用4.4版本了（編譯android4.0係統使用的是4.4），

現在隻要使用係統自帶的4.6.3（ubuntu12.04）就可以了。

3、jdk版本：sun-java6-jdk

二、編譯：

編譯過程不知道，可以查看官方文檔了。這裏做簡單說明：

1.source build/envsetup.sh 這是向係統導入不同的廠商版本，並添加m命令。

2.lunch 選擇編譯廠商版本。

3.mm 編譯版本

還是看圖說話吧：

當然這裏的lunch full-eng是編譯所有，如果嫌慢，就單獨編譯某一個也可。

再mm就可以編譯了（必須要source了，才有mm命令，而且隻在此terminal有效）

三、編譯中遇到的錯誤：

錯誤太多，做了一些總結，有點亂，如果編譯過程中遇到錯誤，可以來查看：

/bin/bash: bison: command not found

解決方法：sudo apt-get install gcc-multilib

error libGL.so: cannot open shared object file: No such file or directory

OSError: libGL.so: cannot open shared object file: No such file or directory

may appear on Linux systems when you try to launch VNL for the first time. To solve it, create (as administrator) a new link in /usr/lib:

sudo ln -s /usr/lib/libGL.so.1.2 /usr/lib/libGL.so

If you have a 64-bit Linux, use /usr/lib64 instead.

First check that you actually have "libGL.so.1.2" in /usr/lib or /usr/lib64; it might be called "libGL.so.1" or something else instead, or located in another directory, depending on the video drivers. You can use

locate libGL

to find the correct file to link to.

而我使用的是ubuntu 12.04 bit-64位，在/usr/lib/並沒有libGL.so文件。

可以使用locate libGL查找此文件。結果：

找出了這麼多，當然是選擇64位平台下的libGL了。

但是針對這幾個，不知道要選擇哪一個好，還請高手指點。

Failed to load libGL.so

error libGL.so: wrong ELF class: ELFCLASS64

linux係統是64位的，這個命令不支持64位

最佳解決方案，把oralce-lib環境變量設置為lib32即可

最後選擇ln還36位

代碼：hudan@ubuntu:~/android/source/android4.1.1/out$ sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1.2 /usr/lib/libGL.so

再運行編譯好的system.img，出現如下的錯誤：

直接參數-ramdisk ramdisk.img去掉，結果模擬器跑起來了，但不能把內核啟動起來。

no ABI error , when creating an Android virtual device

E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

解決：sudo rm /var/lib/apt/lists/lock

上次make或或者mmm的時候生成一些錯誤的東西

可以使用：make clean 再重新make

解決：rm out/target/common/obj/APPS/ -r （如果還是有這樣的錯誤，就隻能clean了）

四、運行編譯好的係統

vi /etc/profile

增加以下三句

最終運行配置，給大家截個圖：
