SYMPTOMS
If an NMAKE version 1.11, 1.12, 1.13, 1.2, or 1.21 INCLUDE macro, which can be used to modify the include environment variable, is created from other macros, the text substitution will not be done when there is an implied use of the include environment variable with the !INCLUDE directive.



RESOLUTION
To work around this problem, do not use macros to redefine the include environment variable. For example, change the assignment from INCLUDE=$(INCLUDE1);$(INCLUDE2) to INCLUDE=C:\DIR1;C:\DIR2



STATUS
Microsoft has confirmed this to be a problem in NMAKE versions 1.11, 1.12, 1.13, and 1.2 for MS-DOS and versions 1.11, 1.12, 1.13, and 1.21 for OS/2. This problem was corrected in NMAKE version 1.3.



MORE INFORMATION
In the following example, the INCLUDE macro is created from the INCLUDE1 and INCLUDE2 macros. When the !INCLUDE is executed, NMAKE will search the directories pointed to by the include environment variable for the file TEST.INC.

However, at this point the INCLUDE macro is still equal to $(INCLUDE1);$(INCLUDE2) and has not been expanded out to C:\DIR1;C:\DIR2, so the include environment variable has not been modified yet. If the file TEST.INC is not in the current directory, NMAKE will generate the error:

fatal error U1052: file 'test.inc' not found

If the INCLUDE macro is explicitly used in a command line, it will be expanded correctly.

Sample Makefile
/* Command line options needed: None

INCLUDE1=C:\DIR1 INCLUDE2=C:\DIR2

INCLUDE=$(INCLUDE1);$(INCLUDE2)

!INCLUDE 

ALL: @ECHO Made it!

Additional query words: 1.11 1.12 1.13 1.20 1.21
