Ubuntu下搭建eclipse C/C++开发环境 [2014-01-16更新]

1. 安装eclipse

$ sudo apt-get install -y eclipse eclipse-pde eclipse-jdt

------------------------------------------

2. 安装C/C++插件（CDT）

运行eclipse，选择 Help --> Install New Software... 菜单项
在 Work with 输入 http://download.eclipse.org/releases/galileo/

依次安装（存在依赖关系，必须按顺序安装，安装完一个后重启eclipse再安装下一个）：

Programming Languages --> Eclipse C/C++ Development Tools

------------------------------------------

3. 配置环境变量

运行eclipse，选择Windows --> Preferences --> C/C++ --> Environment
菜单项

添加 C_INCLUDE_PATH=/usr/local/include:/usr/lib/gcc/i486-linux-gnu/4.4.3/include:/usr/lib/gcc/i486-linux-gnu/4.4.3/include-fixed:/usr/include
C_INCLUDE_PATH 的值通过下述操作获得：
$ echo "int main() { return 0; }" > hello.c
$ gcc -v hello.c
...
#include "..." search starts here:

#include <...> search starts here:

 /usr/local/include

 /usr/lib/gcc/i486-linux-gnu/4.4.3/include

 /usr/lib/gcc/i486-linux-gnu/4.4.3/include-fixed

 /usr/include

添加 CPLUS_INCLUDE_PATH=/usr/include/c++/4.4:/usr/include/c++/4.4/i486-linux-gnu:/usr/include/c++/4.4/backward:/usr/local/include:/usr/lib/gcc/i486-linux-gnu/4.4.3/include:/usr/lib/gcc/i486-linux-gnu/4.4.3/include-fixed:/usr/include
CPLUS_INCLUDE_PATH 的值通过下述操作获得：
$ echo "int main() { return 0; }" > hello.cpp
$ gcc -v hello.cpp
...
#include "..." search starts here:

#include <...> search starts here:

 /usr/include/c++/4.4
