使用g++4.6.1，我在尝试包含xaudio2.h时遇到了许多C++编译错误

Using g++ 4.6.1 I get many C++ compile errors when trying to include xaudio2.h

我有一个c++Windows应用程序，它可以使用Visual Studio 2010进行良好编译。我还想拥有使用MinGW（在Windows7-64 PC上）编译它的能力。当g++处理xaudio2.h头文件时，我会得到下面列出的错误。除了手动破解包含文件外，还有人知道修复程序吗。

以下是xaudio2.h:中的行

DEFINE_CLSID(XAudio2, 5a508685, a254, 4fba, 9b, 82, 9a, 24, b0, 03, 06, af);
DEFINE_CLSID(XAudio2_Debug, db05ea35, 0329, 4d4b, a5, 3a, 6d, ea, d0, 3d, 38, 52);
DEFINE_IID(IXAudio2, 8bcf1f58, 9fe7, 4583, 8a, c6, e2, ad, c4, 65, c8, bb);

看起来定义在comdecl.h中为：

#define DEFINE_CLSID(className, l, w1, w2, b1, b2, b3, b4, b5, b6, b7, b8) 
            class DECLSPEC_UUID_WRAPPER(l##-##w1##-##w2##-##b1##b2##-##b3##b4##b5##b6##b7##b8) className; 
            EXTERN_C const GUID CLSID_##className
#define DEFINE_IID(interfaceName, l, w1, w2, b1, b2, b3, b4, b5, b6, b7, b8) 
            interface DECLSPEC_UUID_WRAPPER(l##-##w1##-##w2##-##b1##b2##-##b3##b4##b5##b6##b7##b8) interfaceName; 
            EXTERN_C const GUID IID_##interfaceName

找到了一个有效的技巧。包括XAudio2，就好像来自C，而不是C++。

#undef __cplusplus
#include <xaudio2.h>
#define __cplusplus

这可能有助于解释GCC连接。
