ubuntu 14.04 andorid4.4 编译环境以kernel编译环境搭建

1、安装jdk。下载 jdk-6u45-linux-x64.bin，改变权限chmod 777 jdk-6u45-linux-x64.bin然后解压 ./jdk-6u45-linux-x64.bin我是把下载的jdk1.6.0_45直接放在个人目录（home下面的账户名wshine）下。2、添加到默认路径sudo update-alternatives --install /usr/bin/jar jar /home/wshine/jdk1.6.0_45/bin/jar 60sudo update-alternatives --install /usr/bin/java java /home/wshine/jdk1.6.0_45/bin/java 60sudo update-alternatives --install /usr/bin/javac javac /home/wshine/jdk1.6.0_45/bin/javac 60sudo update-alternatives --install /usr/bin/javap javap /home/wshine/jdk1.6.0_45/bin/javap 60sudo update-alternatives --install /usr/bin/javadoc javadoc /home/wshine/jdk1.6.0_45/bin/javadoc 60选泽：sudo update-alternatives --config jarsudo update-alternatives --config javasudo update-alternatives --config javacsudo update-alternatives --config javapsudo update-alternatives --config javadoc3、改变环境变量

vim ~/.bashrc
或sudo gedit ~/.bashrc

PS :ubuntu 自带的gedi，比较好用。

按shit+g在文件末尾加入以下内容

export JAVA_HOME=/[code]home/wshine/jdk1.6.0_45

export JRE_HOME=${JAVA_HOME}/jreexport CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/libexport PATH=${JAVA_HOME}/bin:$PATH[/code]退出保存，并运行下面的命令使之生效

source ~/.bashrc

测试启动终端，输入以下命令

java -versionjavac

4、安装需要的包sudo apt-get install git gnupg flex bison gperf build-essentialsudo apt-get install zip curl libc6-dev libncurses5-dev:i386 x11proto-core-devsudo apt-get install libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386sudo apt-get install libgl1-mesa-dev g++-multilib mingw32 tofrodossudo apt-get install python-markdown libxml2-utils xsltproc zlib1g-dev:i386sudo apt-get install vim vim-gnome vim-doc vim-scripts exuberant-ctags cscope gawkcurl rar unrar zip unzip ghex nautilus-open-terminal p7zip-full tree uml-utilitiesmeld gimp dos2unix unix2dos tofrodos python-markdown subversionsudo apt-get install git-core flex bison gperf gnupg build-essential zip curl zlib1g-devlibc6-dev lib32ncurses5-dev lib32z1 x11proto-core-dev libx11-dev libreadline-gplv2-devlib32z-dev libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown libxml2-utilsxsltproc libxml-simple-perlsudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so5、编译kernel时有遇到这个问题，安装了个lzop包后，问题搞定。sudo apt-get install lzopmake[2]: Warning: File `arch/arm/boot/compressed/../Image' has modification time 0.75 s in the futureLZO arch/arm/boot/compressed/piggy.lzo/bin/sh: 1: lzop: not foundmake[2]: *** [arch/arm/boot/compressed/piggy.lzo] Error 1make[1]: *** [arch/arm/boot/compressed/vmlinux] Error 2make: *** [uImage] Error 2 首先把JDK拷贝到指定的目录，然后解压缩拷贝后的文件到指定的目录中，具体命令行如下：$ sudo cp jdk-6u30-linux-i586.bin /usr/local #拷贝jdk到/usr/local目录$ cd /usr/local #进入/usr/local目录$ chmod 544 jdk-6u30-linux-i586.bin #修改权限$ sudo ./jdk-6u30-linux-i586.bin #解压bin文件$ sudo ln -s jdk1.6.0_30 jdk-6 #为文件创建名了jdk-6的软链接（类似Win的快捷方式）$ sudo rm jdk-6u30-linux-i586.bin #删除bin文件4.     其次设置环境变量，主要是PATH、CLASSPATH和JAVA_HOME，注意PATH最后所添加的bin目录：$ sudo vi /etc/environmentPATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/jdk-6/bin"CLASSPATH="/usr/local/jdk-6/lib"JAVA_HOME="/usr/local/jdk-6"
