Compile error after adding #define WPP_GLOBALLOGGER

My driver is currently using WPP tracing to assist my development and
debugging. I need to see details that occur early, and decided to attempt
using the Global Logger Session. After reading several related pages, I
added the #define WPP_GLOBALLOGGER to my trace.h file after the #define
WPP_CONTROL_GUIDS macro definition.

I now get the following compile error in only the .cpp file that has the
WPP_INIT_TRACING macro call (SwrxDriver.cpp in the DriverEntry function):

....SwrxDriver.tmh(2048) : error C2664: 'RtlStringFromGUID' : cannot convert
parameter 1 from 'LPCGUID' to 'const GUID &'

When I commend out the #define WPP_GLOBALLOGGER macro, the driver compiles
without comment.

Any suggestions? John Bond

try wrapping the #include of the tmh file in an extern "C" { } block

Thx Doron, but I still get the same compile error:

The last line is the point of the compile error... hope this helps.

I guess your driver is compiled with __cpluplus defined.
That would #define REFGUID differently.
It is not clear (unless you analyze the output of `cl.exe /showIncludes`)
who first defines _REFGUID_DEFINED and/or if your precompiled header
can be wrapped with #ifndef __cplusplus/extern "C" {/#endif.
Try to have the header that first defines REFGUID
to be trated as a C compilation unit.

Good Luck with header reshuffling.

what WDK are you using? I think we fixed this in the win7 wdk.
