Android编译环境的配置

1、Android 在 ubuntu10.04 编译环境的配置一 .软件的安装1丄inux系统是安装在Vmware中，所以必须下载Vmware,这里采用的版本 为 Vmware.Workstation.v7.1.0.Lite.rar下载地址：（暂时没有找到 ）安装完 vmware 后，可以让它自动检测新版本并升级。2下载Ubuntu，这里采用的版本是10.04，文件名为ubuntu-10.04-desktop-i386.iso下载地址为：http:3. 下载完成后，安装 ubuntu10.04,由于采用vmware安装，故只需简单设置即可，其他采用默认设置安 装，需要注意的是vmware的空间应该

2、分配大一些（最好是大于 60GB）,不 然，以后要扩展空间时比较麻烦。4. Ubuntu 的默认安装的用户不是超级用户 root, 因此要使用超级用户 root， 必须通过下面的命令来开启：(1) .使用默认用户进入 ubuntu 的界面，打开 shell,(2) .在 shellxx 输入命令：sudo passwd root ,然后按确认键；(3) .按下确认键后，系统要求你设置root 用户的密码，连续输入 2 次后，root 用户的密码设置成功；(4) .重新启动系统即可使用超级用户登陆 .5. 使用超级用户登陆后，开始配置 Android 的编译环境：(1) .由于ubu ntu的软

3、件中心提供的是java6,而编译An droid需要的是java5, 为了保证采用命令安装时系统能够自动找到需要的java5,我们必须修改apt里面的 sources.list:rootubuntu:/#vim /etc/apt/sources.list在该文件末添加如下网址：# update the sun-java5-jdk from as follow:deb http:deb http:(2) .采用命令安装所需软件：rootubuntu:/# sudo apt-get install git-core gnupg sun-java5-jdk flex bison gperflibsd

4、l-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-devzlib1g-dev（由于 apt-get 能够自动区分命令，故采用一条命令即可 .此命令安装的软件有:git-core ;gnupg ;sun-java5-jdk ;flex ;bison;gperf ;libsdl1.2-dev；libesd0-dev；libwxgtk2.6-dev; build-essential; zip; curl ;libncurses5-dev ;zlib1g-dev当安装至U sun- java5-jdk 时，需要

5、手动点击协议。(3) .等待(2) 完成后，可以再安装一个 Valgrind 和 meld 软件 (也可以不安装)：rootubuntu:/# sudo apt-get install valgrindrootubuntu:/# sudo apt-get install meld至此，编译环境所需软件全部安装完成。二.Android的编译1由于软件是直接从Freescale直接拷贝，故不需要下载和更新patch，我们可以进入相应目录直接编译。(1) .在/mntxx建立相应文件夹：rootubuntu:/#mkdir -p /mnt/vdisk/software/imx-android-r9(

6、2) .拷贝文件：rootubuntu：/#cp -i /mnt/hgfs/LinuxFile/Android/myandroid_r9.tgz/mnt/vdisk/software/imx51-android-r9/(3) .解压文件：rootubuntu:/#cd /mnt/vdisk/software/imx51-android-r9/rootubuntu:/mnt/vdisk/software/imx51-android-r9#tar -zvxf myandroid_r9.tgz(4) .解压完成后，为了方便区分版本，我们需要重新命名下 : rootubuntu:/mnt/vdisk/

7、software/imx51-android-r9#mv myandroidr9(5) .解压文件 imx-android-r9.tar.gzrootubuntu:/mnt/vdisk/software/imx51-android-r9#tar -zvxfimx-android-r9.tar.gz(6) .安装 tools:rootubuntu:/mnt/vdisk/software/imx-android-r9#cd imx-android-r9/tool/rootubuntu:/mnt/vdisk/software/imx-android-r9/imx-android-r9/tool#ta

8、r xzvfgcc-4.1.2-glibc-2.5-nptl-3.tar.gz -C /opt(7).编写环境变量：我们在 opt 上建立一个 android-env 的文件，并把如下内容拷贝到该文件中：rootubuntu:/mnt/vdisk/software/imx-android-r9/imx-android-r9/tool#cd/opt/ rootubuntu:/opt#vim android-env#!/bin/bashexport ARCH=armexport CROSS_COMPILE=/opt/gcc-4.1.2-glibc-2.5-nptl-3/arm-none-linux

11、buntu:/mnt/vdisk/software/imx-android- r9/myandroidr9/bootable/bootloader/uboot-imx#make 当编译完成后，会生成 u-boot.bin 文件。The above u-boot.bin has 1024KB padding at the head of file,for example firstexecutable instruction is at the offset 1Krootubuntu: /mnt/vdisk/software/imx-android- r9/myandroidr9/bootabl

13、mx#cd /mnt/vdisk/software/imx- android-r9/myandroidr9/kernel_imx/2 .设置mkimage的路径：rootubuntu:/mnt/vdisk/software/imx51-android-r9/myandroidr9/kernel_imx#export PATH=/mnt/vdisk/software/imx51-android-r9/myandroidr9/bootable/bootloader/uboot-imx/tools：$PATH3 .开启编译 ：rootubuntu：/mnt/vdisk/software/imx51-

14、android-r9/myandroidr9/kernel_imx#make imx5_android_defconfigrootubuntu：/mnt/vdisk/software/imx51-android-r9/myandroidr9/kernel_imx#make uImage4 . 当编译完成时：With a successful build in either of the above case, the generated kernel image is/mnt/vdisk/software/imx51-android-r9/myandroidr9/kernel_imx/arch

15、/arm/boot/uImage.Generate uImage to be loaded by u-bootTo generate uImage from the built zImage, generate a uImage based on the abovezImage as follows:rootubuntu: /mnt/vdisk/software/imx-android-r9/myandroidr9/kernel_imx# cdarch/arm/boot/rootubuntu:/mnt/vdisk/software/imx-android- r9/myandroidr9/ker

22、 Android Root Filesystem -d ./ramdisk.img ./uramdisk.img至此，编译完成。三.远程操作需要安装的软件I.Ubuntu默认是没有安装SSH2软件的，所以我们要想远程登陆，必须首先安装 SSH2:rootubuntu:/#sudo apt-get install ssh2安装完成后，系统将打开 22 端口，这样就可以在远程登陆操作系统了。2为了在远程操作服务器上的共享文件，我们安装了samba软件：rootubuntu:10.04上要想启动samba我们必须再安装samba4:rootub un tu:/#sudo apt-get install samba43.安装完成后，我们必须更改samba的配置文件：rootubu
