unresolved external symbol _MEDIASUBTYPE_RGB32

Hi All,

I am writinga media (Camera streaming) driver. The driver works fine on
WinXP but I can't build it for Win2000. It encounters this error,
unresolved external symbol _MEDIASUBTYPE_RGB32. I was unable to find the lib
which exports this symbol.

Using the XP driver on WIn2000 leads to the crash of System.I know
strmiids.lib exports this symbol in WinXP DDK.

Has someone encountered this problem earlier?
How to overcome it?
Please help

Maybe you could use a local copy of the GUID with the same value,
instead of the one exported by the library.

Thanks for the reply.

But I get this error message while linking. All this symbols are defined in
uuids.h

Right. MEDIASUBTYE_RGB32 is an external reference to a 16-byte constant.
Someone has to define that constant. You can hope to find it in a library,
or you can define them yourself by adding
#include <initguid.h>
before you include <uuid.h>.
