WPP on Win2K?

NTFSD
1

NTFSD Folk:

I’m having problems getting WPP working on Win2K. Everything builds and
executes fine on XP/2003. (It’s a minifilter, but I don’t think that’s a
factor.)

Per the documentation, I’ve added this line in sources:

RUN_WPP=$(SOURCES) -km -gen:{km-w2k.tpl}*.tmh

But it still gets roughly a zillion compile errors (mostly macro and struct
redefinitions). I can’t seem to find a combination of #includes that work.

I’m using IFS build 1414. Any clues?

Thanks,
Ken

On second thought, being a minifilter could be a significant factor.

The basic conflict appears to be between ntifs.h and ntddk.h, since they
define a lot of the same things.

The minifilter includes fltkernel.h, which includes ntifs.h; WPP (.tmh file)
includes ndttk.h, but only on Win2K.

Maybe WPP is incompatible with minifilters on Win2K?

Ken -

Your WPP command line should look something like this for W2K (notice the
undocumented -dll option!)

RUN_WPP=$(SOURCES) -km -dll -gen:{km-w2k.tpl}*.tmh

If you ever figure out a way to build a single Filter Manager based driver
image for W2K/XP/WS03 with WPP tracing enabled, let me know. I gave up on
that one.

The -dll didn’t seem to improve anything and added another error:

error C2496: ‘WPP_GLOBAL_Control’ : ‘selectany’ can only be applied to data
items with external linkage

Anyhow, it looks like this handles the bulk of the problems I’ve seen. This
is in the common header I use:

#include <fltkernel.h>

// Suppress invocation of ntddk.h
#define NTDDK

#ifndef UNICODE_STRING_MAX_BYTES
#define UNICODE_STRING_MAX_BYTES ((USHORT) 65534)
#endif

#ifndef RTL_NUMBER_OF
#define RTL_NUMBER_OF(x) (sizeof(x)/sizeof(x[0]))
#endif

#ifndef RtlInitEmptyUnicodeString
#define RtlInitEmptyUnicodeString(_ucStr,_buf,_bufSize) <br> ((_ucStr)->Buffer = (_buf), <br> (_ucStr)->Length = 0, <br> (_ucStr)->MaximumLength = (USHORT)(_bufSize))
#endif

For some reason, the last 3 macros aren’t defined in the W2K version of
ntifs.h (there may be more that I’m not using, too).

HTH,
Ken

Should have looked a little deeper in my sources as well – it was over a
year ago that I encountered this problem and I do have WPP tracing in a W2K
build working.

Note: In my case they are .cpp for strong typing only. Hence the extern “C”
nonsense.

Including ntifs.h as follows:

#ifndef NTIFS
#ifdef __cplusplus
extern “C” {
#endif
#include <ntifs.h>
#ifdef __cplusplus
}
#endif
#endif NTIFS

In each source module using WPP I have the following:

#if defined(USE_WPP_TRACING)
#if defined(BUILD_W2K)
#define NTDDK
extern “C” {
#endif

#include “module.tmh”

#if defined(BUILD_W2K)
}
#endif
#endif

The key here may be the #define NTDDK to avoid ntddk.h being included over
ntifs.h

One more thing…

You need to call WPP_INIT_TRACING() with a DeviceObject and not a
DriverObject on W2K.
