1. 简介
本文描述在X86 64位机(cpu i5)建立Android 4.2编译环境。
2. 安装Ubuntu12.10
从http://releases.ubuntu.com/quantal/上下载PC (Intel x86) desktop image,然后进行安装即可。
2.1 安装vim
sudo apt-get install vim
2.2 设置root密码及root登录
sudo passwd root
vim /etc/lightdm/lightdm.conf
在最后增加一行：
greeter-show-manual-login=true
2.3 安装ssh服务器
sudoapt-get install openssh-server
重启系统则生效。
2.4 安装并配置samba
sudo apt-get install samba
用以下smb.conf替换/etc/samba/smb.conf，并把原来的做一个备份，此配置将使系统每个用户都以自己的根目录访问samba。
# smb.conf is the main Samba configuration file. You find a full commented # version at /usr/share/doc/packages/samba/examples/smb.conf.SUSE if the # samba-doc package is installed. # Date: 2007-09-22 [global] workgroup = WORKGROUP printing = cups printcap name = cups printcap cache time = 750 cups options = raw include = /etc/samba/dhcp.conf logon path = \\%L\profiles\.msprofile logon home = \\%L\%U\.9xprofile logon drive = P: # usershare allow guests = Yes domain logons = Yes domain master = Yes local master = Yes os level = 65 preferred master = Yes null passwords = yes security = share guest ok = yes usershare max shares = 100 security = user encrypt passwords = yes smb password file = /etc/samba/smbpasswd # root = jerry #[tim] # comment = tim # inherit acls = Yes # path = /home/tim # read only = No [homes] comment = Home Directories browseable = no writable = yes valid users = %S
2.5 创建Linux及samba用户
相关命令如下所示：
// Create Linux user and root directory #adduser tim // Create samba user #mbpasswd -a tim // start samba service #service smbd restart
3. 建立Android4.2编译环境
•Python 2.6 -- 2.7：可从python.org下载，Ubuntu12.10中已经包含Python2.7；
•GNU Make 3.81 -- 3.82：可从gnu.org下载，Ubuntu12.10中已经包含3.81；
•JDK 6：Android2.3以上的版本，可Java SE 6 Downloads上下载jdk-6u45-linux-x64.bin，然后进行安装；
•Git 1.7或以上版本：可从 git-scm.com上下载。
3.1安装必要的编译工具包
$ sudo apt-get install git 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 tofrodos \ python-markdown libxml2-utils xsltproc zlib1g-dev:i386 $ sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so
安装上面的会导致桌面菜单栏不见了，下面的就没有问题。
$ apt-get install git gnupg flex bison gperf build-essential zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown libxml2-utils xsltproc zlib1g-dev:i386 $ sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so
经过测试发现，只要执行了: apt-get install libgl1-mesa-glx:i386，它将删除以下三个模块，从面导致Ubuntu桌面不见了。
The following packages will be REMOVED: libgl1-mesa-dri ubuntu-desktop xorg
3.2 安装JDK6
1) 下载jdk-6u45-linux-x64.bin
2) 安装JDK6
chmod a+x jdk-6u45-linux-x64.bin sudo mv jdk-6u38-linux-x64.bin /usr/java cd /usr/java sudo ./jdk-6u45-linux-x64.bin
3) 修改配置文件/root/.bashrc(对所有用户有效)
export JAVA_HOME=/usr/java/jdk1.6.0_45 export PATH=$PATH:$JAVA_HOME:$JAVA_HOME/bin:$JAVA_HOME/jre/bin重启系统，使用java --version确认java版本是否为：1.6.0_45
4. 安装SDK和NDK
4.1 安装SDK
1) 下载SDK(如：android-sdk_r22.0.5-linux.tgz)从http://developer.android.com/sdk/index.html
2) copy SDK到/usr/android/
3) tar xvf android-sdk-r22.0.5-linux.tgz
export SDK_HOME=/usr/android/android-sdk-linux export PATH=$PATH:$SDK_HOME/tools:$SDK_HOME/platform-tools
5) 更新SDK：tools/android update sdk --no-ui 或tools/android sdk(有界面进行选择)
4.2 安装NDK
1)下载NDK(如：android-ndk-r9-linux-x86_64.tar.bz2) 从以下地址:
http://developer.android.com/tools/sdk/ndk/index.html
2) copy NDK到/usr/android/
3) tar xvf android-ndk-r9-linux-x86_64.tar.bz2
export PATH=$PATH:/usr/android/android-ndk-r9
