编写makefile+sources文件

makefile 文件

#
# DO NOT EDIT THIS FILE!!!  Edit .\sources. If you want to add a new source
# file to this component.  This file merely indirects to the real make file
# that is shared by all the driver components of the Windows NT DDK
#


!INCLUDE $(NTMAKEENV)\makefile.def

sources 文件

TARGETNAME=HelloDDK
TARGETTYPE=DRIVER
TARGETPATH=OBJ
 
SOURCES=HelloWord.cpp\
