漫长的编译开始了，当然成功不会一蹴而就的，不出所料，错误出现了

继续求教于，Google和百度吧，原来是gcc版本的问题

$gcc --version

gcc (Ubuntu 4.4.1-4ubuntu9) 4.4.1

Copyright (C) 2009 Free Software Foundation, Inc.

This is free software; see the source for copying conditions.  There is NO

研究了一下发现问题主要出在Ubuntu10.4预置了gcc的版本是4.4，该版本编译时对语法要求比较高，因此无法编译源代码，解决方法就是将gcc-4.4降级成gcc-4.3

具体操作：

sudo apt-get remove gcc-4.4（卸载gcc-4.4）

sudo apt-get remove g++-4.4（ 卸载g++-4.4）

sudo apt-get install g++-4.3（安装g++-4.3）

安装完4.3版本后，执行gcc --version后会发现版本仍然是4.4，因为gcc已经和4.4版本进行了链接，因此需要对gcc重新进行链接

具体操作：sudo ln -f /usr/bin/gcc-4.3 gcc

                    sudo ln -f/usr/bin/g++-4.3 g++

这样就可以用4.3版本的gcc和g++将原来的覆盖掉，重新进入android源码目录执行make就可以正常编译～～

Q. I'm getting the following error while compiling application under CentOS / RHEL / Fedora Linux 64 bit edition:

/usr/include/gnu/stubs.h:7:27: error: gnu/stubs-32.h:

No such file or directory

How do I fix this error?

A. You need to install the glibc-devel package. It contains the object files necessary for developing programs which use the standard C libraries (which are used by nearly all programs). If you are developing programs which will use the standard C libraries, your system needs to have these standard object files available in order to create the executables.

Install glibc-devel if you are going to develop programs which will use the standard C libraries.
# apt-get install g++-multilib

前几天下载了Android 2.3.1的源代码并在Ubuntu 10.04(32位)上编译通过。这篇文章简要记录了下载、编译的过程。

关于搭建Android开发环境的文章已经有很多，本文只简要介绍一下，做为备忘。

[ 编译前的准备 ]

这一步安装获取源代码以及编译所需要的软件，使用如下命令：

 $ sudo aptitude install git-core gnupg flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev

sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev ia32-libs x11proto-core-dev libx11-dev lib32readline5-dev lib32z-dev java-common unixodbc 

另外，参考别人编译Android 2.3的经验，安装了下列软件包：

$ sudo apt-get install lib64z1-dev libc6-dev-amd64 g++-multilib lib64stdc++6 

注意：32 bit Required Packages 为

 git-core gnupg sun-java5-jdk flex bison gperf build-essential zip curl zlib1g-dev  libsdl-dev libesd0-dev libwxgtk2.6-dev libncurses5-dev  

而64 bit 下的  Required Packages 为 git-core gnupg flex bison gperf build-essential zip curl sun-java6-jdk zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev ia32-libs x11proto-core-dev libx11-dev lib32readline5-dev lib32z1-dev

in egl.cpp, at the line 554 :
const Region copyBack(Region::subtract(oldDirtyRegion, dirtyRegion));
just remove the 'const' and retry.

There is a lot of confusion surrounding the work flow in the Android source tree, so allow me to simplify:

1. Follow the initial instructions for downloading the source at:

   http://source.android.com/download

2. Set up your environment to build the engineering build for the generic device and generic product. This is similar to the SDK, but with a few pieces missing.
   
$ source build/envsetup.sh
$ lunch 1

3. To build for the first time:

   $ make
   
   If you have a multi-core system, you can build with make -jN where N is twice the number of cores on your machine. This should speed up the first build considerably.

4. To launch the emulator from your build:

   $ ./out/host/<your-machine-type>/bin/emulator
   
   On my system <your-machine-type> is linux-x86.

   NOTE: The emulator knows where to find system and data images as a result of running lunch 1 above. This sets the environment variable ANDROID_PRODUCT_OUT to point to the target directory. For this example, it should be out/target/product/generic/.

5. If you wish to make changes to the source code, there are handy utilities that have been exposed to your environment by source build/envsetup.sh above. For example, if you modify the Email app and just want to rebuild it:

   $ mmm packages/apps/Email

6. To see your changes in the emulator you can run:

   $ adb remount
$ adb sync

   Which will copy the regenerated Email.apk file into the emulator’s /system/app folder, triggering the PackageManager to automatically reinstall it.

7. Or if you change framework resources in frameworks/base/core/res/res/ you could regenerate framework-res.apk with:

   $ mmm frameworks/base/core/res

   Or if you modified even the framework itself you could run:

   $ ONE_SHOT_MAKEFILE="frameworks/base/Android.mk" make framework

   This is a special variation of mmm which is used to build frameworks/base/core/java.

   To sync these changes you must restart the running framework and sync, as with this handy sequence:

   $ adb remount
$ adb shell stop
$ adb sync
$ adb shell start

8. Finally, to debug your changes you can use the DDMS tool to select a process for debug and then attach Eclipse to it. If you have the Eclipse Android Development plugin installed, there is a special DDMS perspective which you can use to choose the process for debug. To attach Eclipse to it, see these instructions:

   http://source.android.com/using-eclipse

   This document also describes how to use Eclipse for development. Any IDE should work with the proper finagling though. Just note that the IDE won’t really by an integrated environment, the final output of APKs, system.img, and even the generation of R.java files will have to be done by make!

   A note about the processes in Android:

   • system_process houses all things under frameworks/base/services. This includes the PackageManagerService, StatusBarService, etc. It has many, many threads (one for each service, and then one main UI thread), so be wary when debugging.
   • com.android.acore hosts Launcher (home), Contacts, etc. You can determine the apps/providers that run here by looking forandroid:process="android.process.acore" in the various AndroidManifest.xml files in packages/.

   Also remember that the “framework” (under frameworks/base/core/java) is not hosted by any one process. It is a library used by most processes, so to debug code there you can usually use a simple demo app that takes advantage of whatever you changed and debug that app’s process. A useful trick for setting up your debug connection is to call Debug.waitForDebugger() during some startup part of an application or system service.

　　http://hi.baidu.com/maxgoto/blog/item/fa000f7bf01135f80ad187d8.html 最近下载了Android 2.1源码，在Ubuntu 9.10上做了一次编译，由于系统为纯净系统，之前没有进行过任何Android的编译，所以需先安装一些必要软件。编译过程参考网上一些文章，做下笔记如下，以供参考：

1. 下载或更新Android源码 至最新，截止到前天(04-09)好像是2.1-r2.

2. Android 要求的 jdk 1.5,而Ubuntu9.10的源里只有JDK1.6. 目前网上解决方法有两种：
    解决方法一： 安装JDK1.5
   1） 根据官方文档里所说,源代码的编译必须使用JDK5才能编译的了，所以这里我们使用jdk5
   2） 需要先更新源,在终端里执行 sudo vim /etc/apt/sources.list
   3） 在source.list里把以下2行拷贝到文档最后面：
        deb http://us.archive.ubuntu.com/ubuntu/ jaunty multiverse
        deb http://us.archive.ubuntu.com/ubuntu/ jaunty-updates multiverse
        保存退出。
   4） 执行 sudo apt-get update 更新源.
   5）配置编译环境并下载JDK5：sudo apt-get install sun-java5-jdk

3. 安装编译过程中必需软件 。根据网上高人的经验，这是编译的最小工具软件集。
    $sudo apt-get install build-essential
    $sudo apt-get install zlib1g-dev
    $sudo apt-get install flex
    $sudo apt-get install libncurses-dev
    $sudo apt-get install libx11-dev
    $sudo apt-get install gperf

4. make .经过漫长的编译过程，编译成功。

2. 切换到9.04的源



sudo apt-get update



3. update之后，用



sudo apt-get install sun-java5-jdk 即可安装java 1.5





4. 安装后进行设置：



sudo update-alternatives --config java



sudo update-java-alternatives -s java-1.5.0-sun
