How to Delete Fake Error Warnings?

Hello from Japan, sorry for my broken English.

I am now building a project with androidWorks.
I succeeded to build it though many red underlines indicated there were errors.
Why am I warned in spite of successful build?
And I am glad if you tell me how to remove these pseudo red lines.

this is due to VS don’t knew where to find .h file that gcc use . you can add them to the include Directories via Project Property>Configuration Properties>C/C++>General>Additional Include Directories.
