[问题]安装eclipse for c/c++出错，请高人指点下

gbd · #1

安装了jdk1.5 然后下载了Eclipse IDE for C/C++ Developers - Linux (63 MB)（3.3.11），解压后运行eclipse，可以进入eclipse界面，但报错:java.lang.ClassNotFoundException: org.eclipse.core.runtime.Plugin[/img]

第一，运行一下java -version确认java的版本是正确的，是java sdk而不是gcj
第二，检查一下你的插件，到eclipse官方网站去看一下cdt需要额外加入哪些插件，是否插件没有安装。一般而言安装了eclipse sdk后在eclipse的更新里面安装cdt好一些。
第三，最好用eclipse官方下载的压缩包手动安装，而不要用源里面提供的软件包。eclipse这样的应用还是要在官方网站下。

谢谢楼上的提醒。我运行java -version 后提示如下，不知道对不对：

java version "1.5.0"
gij (GNU libgcj) version 4.2.1 (Ubuntu 4.2.1-5ubuntu5)

Copyright (C) 2007 Free Software Foundation, Inc.

如果不对，该怎样设置？我到sun下载的 jdk-1_5_0_14-linux-i586.bin 并安装的。

hubert_star · #5

最简单你把jdk/jre/bin和jdk/bin加入到你的path变量前面，或者更改系统的java命令引用，找一下linux安装java的帖子，很多的。

vupiggy · #6

把插件(那些.jar文件)的路径加到CLASSPATH里

gbd · #7

谢谢各位，确实是这个问题，加了路径就对了

gaochang · #8

7楼的 gdb 你是怎么解决你的问题的，

我的也出现这个问题了，，patch变量在那里进行设置，，兄弟们说仔细点好吗

gbd · #9

把这个加在你的home/用户名/.bashrc里面
export PATH=/usr/local/java/jdk1.5.0_14/bin:$PATH
export JAVA_HOME=/usr/local/java/jdk1.5.0_14
export CLASSPATH=$JAVA_HOME/lib:.
注意红色是java sdk 安装的路径，要根据你自己的改下。
