(1)从jdk官方网站http://www.oracle.com/technetwork/java/javase/downloads/jdk-6u29-download-513648.html下载jdk-6u29-linux-i586.bin文件。
(2)执行jdk安装文件
$chmod a+x jdk-6u29-linux-i586.bin $jdk-6u29-linux-i586.bin
(3)配置jdk环境变量
$sudo vim /etc/profile
#JAVAEVIRENMENT exportJAVA_HOME=/usr/lib/java/jdk1.6.0_29 exportJRE_HOME=$JAVA_HOME/jre exportCLASSPATH=$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH exportPATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH
保存后退出编辑,并重启系统。
$sudo apt-get install git-core gnupg flex bison gperf build-essential\ zipcurlzlib1g-devlibc6-devlib32ncurses5-devia32-libs\ x11proto-core-devlibx11-devlib32readline5-devlib32z-dev\ libgl1-mesa-devg++-multilibmingw32tofrodospython-markdown\ libxml2-utils
(1)初始化repo
$cd ~ $mkdir bin $curlhttps://dl-ssl.google.com/dl/googlesource/git-repo/repo>~/bin/repo $chmod a+x ~/bin/repo $exportPATH=$PATH:~/bin(导出环境变量)
(2)下载android最新源码
$mkdir android $cd android $ repo init -u https://android.googlesource.com/platform/manifest -bandroid-4.0.1_r1 ...(输入用户名和邮箱名) $repo sync -j5 ...(此处用5个线程开始下载源码,下载过程及其漫长,需要耐心等待)
$source build/envsetup.sh includingdevice/samsung/maguro/vendorsetup.sh includingdevice/samsung/tuna/vendorsetup.sh includingdevice/ti/panda/vendorsetup.sh includingsdk/bash_completion/adb.bash $make-j4(此处用4个线程编译)
编译完成后,会看到类似的输出:
Targetramdisk:out/target/product/generic/ramdisk.img Targetuserdatafsimage:out/target/product/generic/userdata.img Installedfilelist:out/target/product/generic/installed-files.txt
编译错误:
<命令行>:0:0:错误:“_FORTIFY_SOURCE”重定义[-Werror] <built-in>:0:0:附注: 这是先前定义的位置 cc1plus:所有的警告都被当作是错误 make:*** [out/host/linux-x86/obj/EXECUTABLES/obbtool_intermediates/Main.o]错误 1
原因:
因机器上的gcc版本过高,需替换成4.4.6重新进行编译。
解决方法:
1)安装4.4版本的gcc和g++
$ sudo apt-get install gcc-4.4 $ sudo apt-get install g++-4.4
2)设置gcc版本,使gcc链接到gcc-4.4
$ ls -l /usr/bin/gcc* lrwxrwxrwx 1 root root 7 2011-11-01 23:56 /usr/bin/gcc -> gcc-4.6 -rwxr-xr-x 1 root root 224544 2011-10-06 05:47 /usr/bin/gcc-4.4 -rwxr-xr-x 1 root root 302104 2011-09-17 05:43 /usr/bin/gcc-4.6 $ cd /usr/bin $ sudo mv gcc gcc.bak $ sudo ln -s gcc-4.4 gcc
3)设置g++版本,使g++链接到g++-4.4
$ sudo mv g++ g++.bak $ sudo ln -s g++-4.4 g++
4)设置完毕后,重新进行编译即可
1)设置环境变量:
export PATH=~/android/out/host/linux-x86/bin:$PATH export ANDROID_PRODUCT_OUT=~/android/out/target/product/generic
其中linux-x86/bin存放模拟器emulator工具,product/generic存在编译后的镜像文件。
2)启动模拟器
$emulator emulator:WARNING: system partition size adjusted to match image file (162 MB >66 MB)
启动后的截图:
1)进入android4.0.1源码目录,下载goldfish内核源码
$ mkdir kernel $ cd kernel $ git clone http://android.googlesource.com/kernel/goldfish.git $ cd goldfish $ git branch -a * (no branch) master remotes/origin/HEAD -> origin/master remotes/origin/android-goldfish-2.6.29 remotes/origin/master $ git checkout remotes/origin/android-goldfish-2.6.29
2)修改Makefile
goldfish$ gedit Makefile
修改
ARCH ?=$(SUBARCH) CROSS_COMPILE ?=
为
ARCH ?=arm CROSS_COMPILE ?=arm-eabi-
3)导出交叉编译器目录为环境变量
$ export PATH=$PATH:~/android/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin
4)编译内核
goldfish$ make goldfish_armv7_defconfig goldfish$ make
编译完成后,可看到类似如下的输出:
OBJCOPY arch/arm/boot/zImage Kernel: arch/arm/boot/zImage is ready
5)从模拟器中启动内核镜像
$emulator -kernel ~/android/kernel/goldfish/arch/arm/boot/zImage &
启动模拟器后,可从Settings->System->AboutPhone中查看内核版本信息。
