i wan't use CComPtr CComQIPtr, include atlbase.h
But there are mistakes

Hi, that particular error is easy to get rid of:

// add this empty #define line before #including atlbase.h
#define __pragma(x)
#include "atlbase.h"

Problem is that you're fighting an uphill battle by using MinGW for Microsoft specific stuff, you'll run into lots of other compiler errors, for example when I tried I got "#error Unsupported architecture"

Too much trouble. I don't need intelligent CComPtr and ComQIPtr. I'd better manage the pointer by hand.

Thank you all the same.
