linux下安装eclipse

以下是我在ubuntu-10.10下安装eclipse过程：
安装jdk
    # cd  /opt
    # mkdir java
    # bash  jdk-6u26-linux-i586.bin 
    # mv jdk1.6.0_26 java/
    # mv  /etc/alternatives/java  /etc/alternatives/java.gnu
    # ln  -s  /opt/java/jdk1.6.0_26/bin/java  /etc/alternatives/java

    # export  JAVA_HOME=/opt/java

安装jre 
    # cd  /opt
    # bash  jre-6u26-linux-i586.bin java/
    # mv jre1.6.0_26 java/		
    
安装eclipse
    # cd /opt
    # tar zxvf eclipse-linuxtools-indigo-incubation-linux-gtk.tar.gz
    # export  PATH=/opt/eclipse:$PATH

设置环境变量（在文件末尾添加如下内容）
    # sudo vi /etc/profile 
		export JAVA_HOME=/opt/java
		export CLASSPATH=$CLASSPATH:$JAVA_HOME/jdk1.6.0_26/lib:$JAVA_HOME/jre1.6.0_26/lib
		export PATH=$PATH:$JAVA_HOME/jdk1.6.0_26/bin:$JAVA_HOME/jre1.6.0_26/bin
		export PATH=$PATH:/opt/eclipse
		
安装cdt（c/c++ development toolkit）
     # mkdir  -p  /opt/cdt
     # cd  /opt/cdt
     # unzip  ../cdt-master-5.0.0.zip
     # cp  -r  plugins/*  /opt/eclipse/plugins/
     # cp  -r  features/*  /opt/eclipse/features/

注意:预先装好g++，gcc
