初装Eclipse+CDT+MinGW运行HelloWorld时可能出现如下警告:
Invalid project path:Include path not found
首先假设你的MinGW安装路径为 D:/Developement/MinGW
你的工作空间为 D:/Developement/Workspace
那么你最终生成的HelloWorld.exe的路径就应该是(假设Eclipse以Debug方式自动Build) D:/Developement/Workspace/HelloWorld/Debug/HelloWord.exe
故MinGW的环境变量应该如下配置
PATH = %MinGW%/bin
LIBRARY_PATH = %MinGW%/lib
C_INCLUDE_PATH = ../../../MinGW/include
CPLUS_INCLUDE_PATH = ../../../MinGW/include
则所有警告便消失了,问题得到解决
