win7+eclipse+CDT+cygwin symbol could not be resolved

问题：用eclipse 建立编译C++工程出现错误提示 symbol could not be resolved

解决办法：

1. window -> preferences -> C/C++ -> debug -> source lookup path > Path Mapping
Name:whatever  CompilationPath: \cygdirve\c      Local file system path:C:\

用cygwin下的c盘来替代当前的C盘 来查找需要的库文件


2. indexer:  index source and header files opened  in editor
window -> preferences -> C/C++ -> indexer

OK编译的错误解决了
