Hi

I'm trying to link a program to _TrackMouseEvent
which is described on

http://msdn.microsoft.com/library/psdk/winui/mousinpt_0buc.htm

It's not the same call as TrackMouseEvent, which is described
on

http://msdn.microsoft.com/library/psdk/winui/mousinpt_9gxg.htm

_TrackMouseEvent is part of comctrl32.dll, which is in my link
line.  I checked with objdump --all-headers, and it appears
that the function is present in my copy of the DLL.  This
command writes out symbol names without _ and @n but of course
_TrackMouseEvent still has an underscore since it is part of the
name proper.

But when I try to link, I get an error with 'undefined reference
to _TrackMouseEvent@4'.

Am I using the right option to objdump?  It was the only one I 
could get to tell me the symbols exported, but it doesn't give
the @4 bit so I can't tell whether the parameter number is right.
However I can see from .h files on a VC++ machine that it has
1 parameter, in fact it seems to have the same type as
TrackMouseEvent.

Here's how I try to call it:

extern BOOL WINAPI _TrackMouseEvent(LPTRACKMOUSEEVENT x);

BOOL
betaTrackMouseEvent(void *x)
{
  return _TrackMouseEvent(x);
}

Could it be that ld is stripping both of the _'s from the
start?  I checked my .obj file with objdump --syms and it
reported __TrackMouseEvent@4 as one of the symbols as I 
would expect.

Any ideas?

I'm using the 2.95.2 release of course, on NT4, with SP5
AFAIK.
