1、更新source.list源
gedit /etc/apt/source.list

2、安裝JDK1.6
http://www.oracle.com/technetwork/java/javase/downloads/jdk6downloads-1902814.html
這裏選擇的是jdk-6u43-linux-x64.bin
我將下載的jdk-6u43-linux-x64.bin文件置於/usr/lib/中。
然後修改bin文件權限，使其可執行，在shell中執行：
- sudo chmod u+x /usr/lib/jdk-6u43-linux-x64.bin
執行下面命令，將會出現字幕，持續按回車鍵，直至屏幕顯示要求輸入yes/no，此時輸入y回車，將會把jdk解壓到文件夾，得jdk1.6.0_43目錄。
- sudo /usr/lib/jdk-6u43-linux-x64.bin
下面進行配置，在environment中修改，
- sudo vi /etc/environment
添加如下部分
- PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/lib/jdk1.6.0_43"
CLASSPATH=.:/usr/lib/jdk1.6.0_43/lib
JAVA_HOME=/usr/lib/jdk1.6.0_43
或者直接在/etc/profile中添加：（推薦使用）
- sudo vi /etc/profile
- #JAVAEVIRENMENT
- export JAVA_HOME=/usr/lib/jdk1.6.0_43
- export JRE_HOME=$JAVA_HOME/jre
- export CLASSPATH=$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH
- export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH
由於ubuntu中可能會有默認的jdk，如openjdk，所以，爲了使默認使用的是我們安裝的jdk，還要進行如下工作。
通過這一步將我們安裝的jdk加入java選單,執行:
- sudo update-alternatives --install /usr/bin/java java /usr/lib//bin/java 300
- sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/java/jdk1.6.0/bin/javac 300
- sudo update-alternatives --install /usr/bin/javah javah /usr/lib/jvm/java/jdk1.6.0/bin/javah 300
然後執行,通過這一步選擇系統默認的jdk:
- sudo update-alternatives --config java
- sudo update-alternatives --config javac
- sudo update-alternatives --config javah
這樣，再在shell中輸入，就會顯示系統使用的java是sun的java:
- java -version

/bin/bash: bison: 未找到命令
解決：sudo apt-get install bison
2）

解決：apt-get install xsltproc
4）
/bin/bash: flex: 未找到命令
解決：apt-get install flex
5）prebuilts/tools/gcc-sdk/gcc: 行 40: prebuilts/tools/gcc-sdk/../../gcc/linux-gcc命令爲找到
解決：
$ sudo apt-get install gcc-4.4 g++-4.4

在編譯內核的時候，提示如下錯誤：
- dingq@wd-u1110:~/hwsvn/2sw/1prj_linux/pdu/kernel/linux-2.6.30$ make menuconfig
- *** Unable to find the ncurses libraries or the
- *** required header files.
- *** 'make menuconfig' requires the ncurses libraries.
- ***
- *** Install ncurses (ncurses-devel) and try again.
- ***
- make[1]: *** [scripts/kconfig/dochecklxdialog] Error 1
- make: *** [menuconfig] Error 2
解決辦法：只要安裝libncurses5-dev就夠了。
- sudo apt-get install libncurses5-dev

64位系統用32位的交叉工具鏈
PC：ubuntu12.10-64位
交叉工具鏈：mipsel-linux-gcc-32位
查看工具鏈版本的時候出現一下錯誤：
mipsel-linux-gcc -v
bash: ***/mipsel-linux-gcc : no such flie or directory
解決：
sudo apt-get install ia32-lib*
