Error: name followed by :: must be a class or namespace name

Question

I'm using Windows 8 RP with VS2012RC.

I write a class similar to DirectXBase class provided in code sample Direct3DTutorial, Lesson 5. I add the member below into the class

Platform::Agile<Windows::UI::Core::CoreWindow>  m_window;

The issue is word UI is underlined in red, with tooltip text said:

class platform::Agile<<error_type>>

Error: name followed by '::' must be a class or namepace name.

I've included the file "pch.h" in the source code, the content of which is

#pragma once

#include <wrl.h>
#include <d3d11_1.h>
#include <d2d1_1.h>
#include <d2d1effects.h>
#include <dwrite_1.h> // for IDWriteFactory1
#include <wincodec.h> // for IWICImagingFactory2
#include <agile.h>
#include "basicmath.h"

Answer 1

What sample or type of project template are you using to create this condition?

Answer 2

Hi, it's a static library project. The project files are generated using CMake, instead of Visual Studio "New Project" wizard.

Answer 3

See if this is the reference you are missing:

#include <CoreWindow.h>

Answer 4

Hi, when I add the line

#include <CoreWindow.h>

VS reports "Error, cannot open source file “CoreWindow.h"

I also search the Windows SDK directory "C:\Program Files (x86)\Windows Kits\8.0\Include" and there is no file named "CoreWindow.h".

Answer 5

Look here: C:\Program Files (x86)\Windows Kits\8.0\Include\winrt\CoreWindow.h

Answer 6

The file is not there. I forget to mention that I use the express edition. But I have no problem in building and running a couple of code samples. For example, when I open Direct3DTutorial solution, VS2012RC does not give any error to the line

Platform::Agile<Windows::UI::Core::CoreWindow>  m_window;

Maybe CMake does not support VS2012 very well and generates incorrect project configurations.

Answer 7

It is actually an issue with the Static library (for Metro style apps) project type in VS 2012RC. As a workaround for now, since you are using Express you can install the SDK separately to get the header I mentioned here: Windows Software Development Kit (SDK) for Windows 8 Release Preview.

Is there an offline installer of SDK for Windows 8?

Answer 9

There is. See this thread from the tools forum: Windows 8 SDK Standalone Installer

Answer 11

I've installed SDK and included CoreWindow.h, but the error remains.
