// initialize director
    auto director = Director::getInstance();
    auto glview = director->getOpenGLView();
    if (!glview) { 
        **glview = GLViewImpl::createWithRect("NewCocosProject", Rect(0, 0, 960, 640));**
        director->setOpenGLView(glview);
    }
}

Answer 1

after 2 weeks struggle, I realized that, I created the coco project with PREBUILD library, then after I change source project it won't affect the library, so I get various funny errors, I download the latest coco studio again, when I create new project, it shows the option: prebuilt or source code, so I create with source code projects, then I can run it successfully.
