SYMPTOMS
An attempt to use an NMAKE default macro fails and NMAKE generates a message such as the following:

warning u4006: special macro undefined : '$<'



CAUSE
A space has been inserted between the name of the target and the dependent extensions in an inference rule.



RESOLUTION
In an inference rule, list the dependent file extension followed by the target file extension without any intervening embedded spaces.



MORE INFORMATION
The following makefile examples demonstrate a few of the problems that can result when spaces are embedded in an inference rule. In both cases below, note that the embedded spaces cause NMAKE to run commands incorrectly. If you modify the files to remove the spaces, NMAKE generates the desired commands.

Sample Makefile 1

 * 1) The command executed by NMAKE:
 * 2)    cl {.}
 * 1)    cl {.}

{.}.c {c:\objs\}.obj: cl $*

c:\objs\test.obj: .\test.c

Sample Makefile 2

 * 1) The command executed by NMAKE:
 * 2)    cl
 * 1)    cl

.c .obj: cl $<

ALL: myfile.obj

myfile.obj: myfile.c
