GDI+ 库导致“错误 C2760:语法错误:意外标记‘标识符’，预期‘类型说明符’"在 VS2017 中为 XP 编译时 [英] GDI+ library causes "error C2760: syntax error: unexpected token 'identifier', expected 'type specifier'" in VS2017 when compiled for XP

问题描述

我正在尝试将以下 GDI+ 定义包含在我在 Visual Studio 2017 下编译的 Win32 C++ 项目中:

I'm trying to include the following definitions for GDI+ into my Win32 C++ project that is compiled under Visual Studio 2017:

#include <objidl.h>
#include <gdiplus.h>
#pragma comment (lib,"Gdiplus.lib")

我需要编译这个项目以支持 Windows XP.所以在我选择的项目属性中:Platform Toolset as Visual Studio 2017 - Windows XP (v141_xp):

I need to compile this project to support Windows XP. So in the project properies I selected: Platform Toolset as Visual Studio 2017 - Windows XP (v141_xp):

但是当我编译它时，GDI+ 库给了我这个:

But when I compile it the GDI+ library gives me this:

1>c:program files (x86)microsoft sdkswindowsv7.1aincludeobjbase.h(239): error C2760: syntax error: unexpected token 'identifier', expected 'type specifier'
1>c:program files (x86)microsoft sdkswindowsv7.1aincludegdiplusheaders.h(891): error C4596: 'EmfToWmfBits': illegal qualified name in member declaration
1>c:program files (x86)microsoft sdkswindowsv7.1aincludegdiplusstringformat.h(220): error C4596: 'GetTrimming': illegal qualified name in member declaration

知道如何解决这个问题吗?

Any idea how to fix this?

推荐答案

在COM相关标头的第一个(！)#include之前添加此行以修复objbase.h(239):错误 C2760:语法错误:意外标记标识符"，预期的类型说明符":

Add this line before the very first(!) #include of COM-related header to fix objbase.h(239): error C2760: syntax error: unexpected token 'identifier', expected 'type specifier' :

typedef struct IUnknown IUnknown;

此修复有效，因为错误中提到的 objbase.h(239) 中的行包含 static_cast<IUnknown*>(*pp); 尽管 IUnknown还没有在那个地方宣布.

This fix works, because the line in objbase.h(239) mentioned in the error contains static_cast<IUnknown*>(*pp); despite that IUnknown still haven't been declared in that place.
