This is the template make file. Nothing has to be in makefile.tpl except:
!include $(NTMAKEENV)\makefile.def
The complete text of makefile.tpl is as follows:
# # 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 makefile # that is shared by all the components of the DDK. # !INCLUDE $(NTMAKEENV)\makefile.def
