问题
I'm trying to compile Ogre Wiki Tutorial Framework 1.9 - (Windows line endings) in VisualStudio 2013. Right click on OgreFramework project and choosing Rebuild returns following errors:

But when I do this it works:
Right click on BaseApplication.cpp file and choosing Compile:

Both *.h files have set Configuration Properties -> General -> Item Type shows: C/C++ header
Both *.cpp files have set Configuration Properties -> General -> Item Type shows: C/C++ compiler
I've tried remove and add *.h files to project as mentioned in this post but I got same errors. Mentioned post also says that those errors can be found in some log but I cannot find it. Thanks
EDIT:
BaseApplication.cpp or TutorialApplication.cpp -> Right click -> Properties -> Configuration Properties -> C/C++ -> Output Files -> Object File Name shows: $(IntDir)
OgreFramework project -> Right click -> Properties -> Configuration Properties -> C/C++ -> General -> Additional Include Directories -> <edit> -> Macros -> $(IntDir) shows:
Debug\
回答1:
Problem solved. I had also included in a solution explorer filter which contained other version of BaseApplication.cpp and BaseApplication.cpp (because I've copied project and not created new one) which caused overwriting my original BaseApplication.cpp and BaseApplication.h. All credit goes to @HansPassant.
