Summary:
When using NMAKE to create an Inference Rule for a file with a
nonstandard file extension (for example, not .C, .BAS, .ASM, and so
forth), you must specify the name of the new extension in the
.SUFFIXES list.
More Information:
It is sometimes necessary or desirable to compile a source file with a
nonstandard file extension. For example, you may want your QuickBasic
source-code file to be named TEST.SRC rather than the standard
TEST.BAS. When compiling this file using NMAKE, you can create a new
Inference Rule for that extension. The following is an Inference Rule
to compile a source file with a .SRC extension that is out of date
with respect to the target:
.src.obj:
@echo Compiling Source File
bc $<;
This is not enough, however, to get NMAKE to recognize the .SRC
extension. The name of the extension must be placed in the .SUFFIXES
list, which will alert NMAKE to recognize this extension. Otherwise,
NMAKE will gracefully glide past your compile statement without giving
an error. The following is the syntax for placing the .SRC extension
in a makefile:
.SUFFIXES: .src
The following is a listing of a complete NMAKE file to compile the
Basic source file TEST.SRC, which is out of date with respect to
TEST.OBJ:
.SUFFIXES: .src
.src.obj:
@echo Compiling Source File
bc $<;
test.obj:test.src
