Compiler Error C2632: Type 1 followed by Type 2 is illegal

Question

I'm trying to learn an SDK that requires a header file be included. There are two statements in the header file that says

typedef long long SomeIdentifier_SInt64;

and

typedef unsigned long SomeIdentifier_UInt64;

The compiler (MSVC++ 6) is complaining that this is illegal. If so, does this mean the SDK is broken? I seriously doubt this is the case. Is this legal in other compilers? Is there any way around this?

Thanks.

My environment is MS Windows XP Pro 32-bit.

Answer 1

VC6 is too old and too broken to know "long long". It will compile __int64. VS200x doesn't have a problem with it.

Answer 2

MSVC6 is a pretty old and crappy compiler. Their latest version is much much much (much) better, and you can download it for free on their website.

It did support __int64 and unsigned __int64 though, so if for some reason you can't use the latest version you can search through the SDK headers and replace every instance of long long you find.

Answer 3

You need to use the February 2003 version of the Platform SDK.
