The information in this article applies to:

- Microsoft NMAKE Utility for MS-DOS, versions 1.11, 1.12, 1.13, 1.2, 1.3, 1.4 
- Microsoft NMAKE Utility for OS/2, versions 1.11, 1.12, 1.13, 1.21 
- Microsoft NMAKE Utility for Windows NT, versions 1.4, 1.5 
-------------------------------------------------------------------------------

SYMPTOMS
========

An attempt to use a makefile fails and NMAKE generates the following message:

  warning U4004: too many rules for target 'test.exe'

CAUSE
=====

The makefile contains more than one build dependency block for one target and
the makefile does not use the multiple dependency block separator, a double
colon (::).

RESOLUTION
==========

To eliminate the error, modify the makefile to use the multiple dependency block
separator.

MORE INFORMATION
================

The following makefile example demonstrates this warning.

Sample Makefile 1
-----------------

  all: test.exe

  test.exe : test.c

  cl test.c

  test.exe : test.res

  rc test.res

The following makefile example works as expected.

Sample Makefile 2
-----------------

  all: test.exe

  test.exe :: test.c # Double colons are used here

  cl test.c

  test.exe :: test.res # Double colons are used here

  rc test.res
