Ubuntu12.04 64位下，下载编译Android 2.3源码

Ubuntu12.04 64位下，下载编译Android 2.3源码

1、下载

源码可以在google官方下载到，但是确实太慢了。我在http://www.verycd.com/topics/2906182/ 下载的，感谢上传者。

对于在官网下载的童鞋来说，其官方文档写得还是很清楚http://source.android.com/source/downloading.html

大致过程如下：

创建目录文件夹

$ mkdir ~/bin

$ PATH=~/bin:$PATH

下载repo

$ curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo

$ chmod a+x ~/bin/repo

创建工作目录

$ mkdir WORKING_DIRECTORY

$ cd WORKING_DIRECTORY

初始化repo

$ repo init -u https://android.googlesource.com/platform/manifest -b android-4.0.1_r1

对于下载不同版本的android，只需要指明android对应的版本，对于2.3版本，将命令修改为

$ repo init -u https://android.googlesource.com/platform/manifest -b android-2.3.3_r1

下载源码

$ repo sync

这其中，可能遇到的问题，只有自己百度了。

2、编译

编译环境搭建，查看官方文档http://source.android.com/source/initializing.html

l 安装jdk6

sudo add-apt-repository "deb http://archive.canonical.com/ lucid partner"

$ sudo apt-get update

$ sudo apt-get install sun-java6-jdk

需要注意的是：

n 1、jdk6找不到

E: Package 'sun-java6-jdk' has no installation candidate

解决：

添加这个源：

sudo add-apt-repository "deb http://us.archive.ubuntu.com/ubuntu/ hardy multiverse”

n Jdk安装时的ok键，使用键盘左右键进行选中。

l 依赖环境：

$ sudo apt-get install git-core gnupg flex bison gperf build-essential \

zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev \

libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 \

libgl1-mesa-dev g++-multilib mingw32 openjdk-6-jdk tofrodos \

python-markdown libxml2-utils xsltproc zlib1g-dev:i386

安装过程中，我出现了错误1。解决后：

$ sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so

l 编译

进入源码目录后，执行如下命令：

$ source build/envsetup.sh

$ lunch full-eng

$ make

编译过程中出现了错误2、3、4、5.

l 运行

$ emulator

错误：

1、安装全部库时libc6-dev:i386

错误：

Errors were encountered while processing:

libc6-dev:i386

E: Sub-process /usr/bin/dpkg returned an error code (1)

root@mao-virtual-machine:~# apt-get install libc6-dev:i386

Reading package lists... Done

Building dependency tree

Reading state information... Done

libc6-dev:i386 is already the newest version.

You might want to run 'apt-get -f install' to correct these:

The following packages have unmet dependencies:

libc6-dev:i386 : Depends: linux-libc-dev:i386 but it is not going to be installed

Recommends: gcc:i386 but it is not going to be installed or

c-compiler:i386

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

root@mao-virtual-machine:~# apt-get install linux-libc-dev:i386

root@mao-virtual-machine:~# apt-get install libc6-dev:i386

root@mao-virtual-machine:~# sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 libgl1-mesa-dev g++-multilib mingw32 openjdk-6-jdk tofrodos python-markdown libxml2-utils xsltproc zlib1g-dev:i386

2、错误：/usr/bin/ld: cannot find -lz

host Executable: aapt (out/host/linux-x86/obj/EXECUTABLES/aapt_intermediates/aapt)

/usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.4.5/http://www.cnblogs.com/../libz.so when searching for -lz

/usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.4.5/http://www.cnblogs.com/../libz.a when searching for -lz

/usr/bin/ld: skipping incompatible //usr/lib/libz.so when searching for -lz

/usr/bin/ld: skipping incompatible //usr/lib/libz.a when searching for -lz

/usr/bin/ld: cannot find -lz

collect2: ld returned 1 exit status

make: *** [out/host/linux-x86/obj/EXECUTABLES/aapt_intermediates/aapt] Error 1

缺少lib32z1-dev,安装即可:apt-get install lib32z1-dev

3、编译选项[-fpermissive]

frameworks/base/libs/utils/RefBase.cpp:483:67: error: passing ‘const android::RefBase::weakref_impl’ as ‘this’ argument of ‘void android::RefBase::weakref_impl::trackMe(bool, bool)’ discards qualifiers [-fpermissive]

make: *** [out/host/linux-x86/obj/STATIC_LIBRARIES/libutils_intermediates/RefBase.o] Error 1

修改mk文件：

$ gedit frameworks/base/libs/utils/Android.mk

将：LOCAL_CFLAGS += -DLIBUTILS_NATIVE=1 $(TOOL_CFLAGS)

改为：LOCAL_CFLAGS += -DLIBUTILS_NATIVE=1 $(TOOL_CFLAGS) –fpermissive

需要注意的是：–fpermissive 前边的－是带输入法的，改为不带输入法的 短线就可以了

4、GCC版本过高

host C++: obbtool <= frameworks/base/tools/obbtool/Main.cpp

<command-line>:0:0: error: "_FORTIFY_SOURCE" redefined [-Werror]

<built-in>:0:0: note: this is the location of the previous definition

cc1plus: all warnings being treated as errors

make: *** [out/host/linux-x86/obj/EXECUTABLES/obbtool_intermediates/Main.o] Error 1

原因:

此处编译错误是由于ubuntu 11.10采用了GCC4.6.1导致的。

解决方法：

使用gcc4.4 版本进行编译.

sudo apt-get install gcc-4.4

sudo apt-get install g++-4.4

装完后在/usr/bin目录下

$ ls -l gcc*

lrwxrwxrwx 1 root root 7 2011-10-29 09:11 gcc -> gcc-4.6

-rwxr-xr-x 1 root root 224544 2011-10-06 05:47 gcc-4.4

-rwxr-xr-x 1 root root 302104 2011-09-17 05:43 gcc-4.6

发现gcc 链接到gcc-4.6, 需要将它改为链接到gcc-4.4 :

sudo mv gcc gcc.bak

sudo ln -s gcc-4.4 gcc

同理

ls -l g++*

lrwxrwxrwx 1 root root 7 2011-08-14 15:17 g++ -> g++-4.6

-rwxr-xr-x 1 root root 228640 2011-10-06 05:45 g++-4.4

-rwxr-xr-x 1 root root 306200 2011-09-17 05:39 g++-4.6

需要将g++链接改为g++-4.4:

/usr/bin$ sudo mv g++ g++.bak

/usr/bin$sudo ln -s g++-4.4 g++

再查看gcc和g++版本号：

gcc -v

g++ -v

均显示gcc version 4.4，说明gcc 4.4安装成功。

5、gcc降到4.4后错误

host C++: obbtool <= frameworks/base/tools/obbtool/Main.cpp

host Executable: obbtool (out/host/linux-x86/obj/EXECUTABLES/obbtool_intermediates/obbtool)

g++: selected multilib '32' not installed

make: *** [out/host/linux-x86/obj/EXECUTABLES/obbtool_intermediates/obbtool] Error 1

解决：

sudo apt-get install g++-4.4-multilib
