Oculus SDK 0.4.4 - Errors within ovr_capi_gl.h and ovr_capi.

Hello,

I am trying to compile a project with openGL and OculusSDK 0.4.4 (unsing VS2012). But I get severel errors while compiling in the ovr_capi_gl.h.

I added #include <Windows.h> as mentioned in this thread viewtopic.php?f=20&t=17709 (last post).

It fixed some errors but not everything. So the following errors remained:

This are the lines in the header files:
ovr_capi_gl.h

/// Used to pass GL eye texture data to ovrHmd_EndFrame.
typedef struct OVR_ALIGNAS(8) ovrGLTextureData_s
{
    /// General device settings.
    ovrTextureHeader Header;
    /// The OpenGL name for this texture.
    GLuint           TexId;       
} ovrGLTextureData;

static_assert(offsetof(ovrGLTextureData, TexId) == offsetof(ovrTexture, PlatformData), "Mismatch of structs that are presumed binary equivalents.");

ovr_capi.h

/// Contains platform-specific information about a texture.
typedef struct OVR_ALIGNAS(8) ovrTexture_
{
    ovrTextureHeader Header;
    uintptr_t        PlatformData[8];
} ovrTexture;

Unfortunately I'm absolutely new to this topic. Has anyone an idea to fix the errors?
