Android笔记之二： 环境设置与编译

1. 主机（Host）
    Dell Optiplex 745, Pentium D Processor, Ubuntu 7.10

    # uname -a
    Linux souken-i2 2.6.22-14-generic #1 SMP Tue Dec 18 08:02:57 UTC 2007 i686 GNU/Linux

    # cat /proc/version
    Linux version 2.6.22-14-generic (buildd@terranova) (gcc version 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)) #1 SMP Tue Dec 18 08:02:57 UTC 2007

2. Android 安装笔记 ＠ 2009/01/05

About Android
==============
  *

Development Resources
======================
  * App SDK
   
 
  * Sources
   
   

Install SDK
============
 
  * Downloaded package: android-sdk-linux_x86-1.0_r2.zip
   
  * Install guide:
   

  * steps
    # cd ~
    # mkdir -p android/SDK
    # cd android/SDK
    # cp ~/Download/android-sdk-linux_x86-1.0_r2.zip .
    # unzip android-sdk-linux_x86-1.0_r2.zip
   
    # vi /home/souken-i/.bashrc (Add this line:)
    ------
    export PATH=${PATH}:/home/souken-i/android/SDK/android-sdk-linux_x86-1.0_r2/tools
    ------

    Now the SDK is OK. Run "# emulator" to test.

  * Update Eclipse:

    * Remove current eclipse if have:
      # sudo apt-get remove eclipse   
    * Download latest elipse from:
    * I choose "Eclipse IDE for Java EE Developers (162 MB)" and
      download file: eclipse-jee-ganymede-SR1-linux-gtk.tar.gz
    * Unpack it and add its path to PATH.

    * Version: 3.4.1 Build id: M20080911-1700

  * Install Eclipse plugin for Android: ADT

    * Download latest ADT(I choose ADT-0.8.0.zip) from:
     
    * Following the installing guide to install ADT:
     

Build Enviroment
================

  * Guide:

  * Install Java:
    # sudo apt-get install sun-java6-jdk

  * Install Other library

    # sudo apt-get install flex bison gperf libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev

  * Install SDL
    # sudo apt-get install libsdl-dev
   
    SDL fails to install on my Host. It gives me this message:
    -----------------------
    libsdl1.2-dev:
      依存: libx11-dev しかしそれはインストールされません
      依存: libglu1-xorg-dev しかしそれはインストールされません または
        libglu-dev
    -----------------------

    So I tried to install libx11-dev, this time it gives me another
    error message: 

    -----------------------
    libx11-dev: 依存: libx11-6 (= 2:1.1.1-1ubuntu4) しかし、2:1.1.1-1ubuntu4ja1 はインストールされようとしています
    -----------------------

    But in fact, 2:1.1.1-1ubuntu4ja1 is installed in my host.

    * I skip this package, and to see when and where this package will
      be used.

  * Update git version

    On Ubuntu 7.10, if I use command apt-get command to install git tools,
    the version is 1.5.2. But repo requests that git version is 1.5.4 or
    larger. So, I have to compile it from source code.

      See guide on:
   
    # git clone git://git.kernel.org/pub/scm/git/git.git
    # cd git
    # make prefix=/usr; make install
    # make prefix=/usr all doc info
    # sudo make prefix=/usr install install-doc install-html install-info

    To compile git, install the packages below on Ubuntu for missing header
    files:

      # sudo apt-get install libc6-dev libssl-dev zlib1g-dev libcurl4-openssl-dev libexpat1-dev asciidoc  xmlto texinfo

    * For missing header file, go to web
      and search which package which includes this file.

Get repo tools
==============
   
  * repo is not a new tools. It is just a wrap for git command.

    # mkdir ~/bin
    # curl > ~/bin/repo
    # chmod a+x ~/bin/repo

    Add ~/bin to PATH.

Get Android Source
==================

    # cd ~/android/source
    # repo init -u git://android.git.kernel.org/platform/manifest.git

    # repo sync

Build Android
=============
  
   # cd ~/android/source
   # make

   * compile error:
     prebuilt/linux-x86/sdl/include/SDL/SDL_syswm.h:75: error: syntax error before '}' token
  
     * possibly because of missing package: libsdl-dev
     * I selected package "libx11-6" and did "パッケージ" → "パッケージの固定"
       from Synaptic menu, then I can install libsdl-dev successfully.

  * recompile and wait for the result. (How long will it cost to compile all the source???)
    * It takes about 1 hour to compile all the source. And at last it shows:
      -----------------------------------
      ......
      Generated: (out/target/product/generic/android-info.txt)
      Target system fs image:
      out/target/product/generic/obj/PACKAGING/systemimage_unopt_intermediates/system.img
      Install system fs image: out/target/product/generic/system.img
      Target ram disk: out/target/product/generic/ramdisk.img
      Target userdata fs image: out/target/product/generic/userdata.img
      -----------------------------------

     * These images are for target:
       system.img ramdisk.img userdata.img

       Copy them to the SDK diretory and it works:
      
       # cp out/target/product/generic/*.img
              ~/android/SDK/android-sdk-linux_x86-1.0_r2/tools/lib/images/
       # emulator &

     * But where is the kernel image? (kernel-qemu)
