The information in this article applies to:

  • Microsoft NMAKE Utility for MS-DOS 1.2
  • Microsoft NMAKE Utility for MS-DOS 1.3

This article was previously published under Q75206

SYMPTOMS

The Microsoft NMAKE utility may not invoke inference rules when multiple dependency lines are used for a single target as illustrated in the sample makefile below.

RESOLUTION

To work around this problem, either avoid the use of multiple dependency lines for a single target, or do not use inference rules.

STATUS

Microsoft has confirmed this to be a problem in NMAKE versions noted above. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

When NMAKE processes the following sample makefile, the inference rule to build the executable file is not executed. However, the inference rule to build the object file is executed correctly because the object files are build as one target. Also, the commands stated explicitly for multiple targets are executed correctly.

Sample Makefile

# NMAKE options needed: none
 
# inference rule that should be invoked
.obj.exe:
 
    LINK /INFO TEST.OBJ;
 
all : test.exe
 
# default inference rule executed for single target
test.obj : test.c
 
# inference rule not executed for multiple targets
test.exe :: test.obj
 
test.exe :: test.def
 
    echo Not using .DEF file
