紧急求助!DS编译WDM时出错.

我装了VC6,DDK2000,和DRIVERSTUDIO,用来开发USB的WDM驱动,我用DRIVERSTUDIO去编译他自己带的例子:
USBBULK,    构件USBBULK.SYS时,     为什么有如下错误:

Linking...
usbbulk.obj : error LNK2001: unresolved external symbol \"void __stdcall InitializeCppRunTime(void)\" (?InitializeCppRunTime@@YGXXZ)
.\\objchk\\i386\\usbbulk.sys : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

我已经编译了DS的类库VDMLIBS.

希望高手赐教呀!!!
