First, check the lines in the MAKEFILE that define the build environment to make sure the variable settings match your build environment. The lines of the MAKEFILE you must check are right at the beginning of the MAKEFILE and are shown in the following:
#Change the following variables for your environment
####################################################
CC=..\..\..\..\dev\tools\c932\bin\cl.exe
LINK=..\..\..\..\dev\tools\c932\bin\link.exe
MASM=..\..\..\..\dev\tools\masm611c\mlx
DDKLIB=..\..\..\..\dev\ddk\lib
DDKINCLUDE=..\..\..\..\dev\ddk\inc
H2INC=..\..\..\..\dev\tools\common\h2inc.exe
MAPSYM=..\..\..\..\..\dev\tools\common\mapsym
You may have to edit one or more of these seven lines in order to match the paths in your build environment.
