Eclipse CDT 标准库头文件设置

Eclipse 中新建C 或C ++到项目时，头文件报警，显示“Unresolved inclusion:<stdio.h>” 虽然不影响项目到编译和运行，确也无法查看头文件，让人感觉实在不爽。

在终端下查看C 库文件到路径：

$ echo "int main() { return 0; }" > a1.c

$ gcc -v a1.c

#include "..." 搜索从这里开始：
#include <...> 搜索从这里开始：

/usr/lib/gcc/i686-Linux-gnu/4.6.1/include
/usr/local/include
/usr/lib/gcc/i686-linux-gnu/4.6.1/include-fixed
/usr/include/i386-linux-gnu
/usr/include

搜索列表结束。

……

查看C++ 库文件到搜索路径：

$ echo "int main() { return 0; }" > a1.cpp

$ g++ -v a1.cpp

#include "..." 搜索从这里开始：
#include <...> 搜索从这里开始：
/usr/include/c++/4.6
/usr/include/c++/4.6/i686-linux-gnu/.
/usr/include/c++/4.6/backward
/usr/lib/gcc/i686-linux-gnu/4.6.1/include
/usr/local/include
/usr/lib/gcc/i686-linux-gnu/4.6.1/include-fixed
/usr/include/i386-linux-gnu
/usr/include
搜索列表结束。

在eclipse中菜单Window --> Preferences --> C/C++ --> Build --> Environment添加环境变量

C_INCLUDE_PATH =/usr/lib/gcc/i686-linux-gnu/4.6.1/include:/usr/local/include:/usr/lib/gcc/i686-linux-gnu/4.6.1/include-fixed:/usr/include/i386-linux-gnu:/usr/include

CPLUS_INCLUDE_PATH =/usr/include/c++/4.6:/usr/include/c++/4.6/i686-linux-gnu/.:/usr/include/c++/4.6/backward:/usr/lib/gcc/i686-linux-gnu/4.6.1/include:/usr/local/include:/usr/lib/gcc/i686-linux-gnu/4.6.1/include-fixed:/usr/include/i386-linux-gnu:/usr/include

记得选中下面的Append variables to native environment.

添加完后重启Eclipse 新建项目即可。
