Creating a single makefile that works for several projects. You can define a macro that replaces a dummy filename in the makefile with the specific filename for a particular project.Macros offer a convenient way to replace a particular string in the makefile with another string. You can define your own macros or use predefined macros. Macros are useful for a variety of tasks, such as:
Creating a single makefile that works for several projects. You can define a macro that replaces a dummy filename in the makefile with the specific filename for a particular project.
Controlling the options NMAKE passes to the compiler or linker. When you specify options in a macro, you can change options throughout the makefile in a single step.
Specifying paths in an inference rule. (For an example, see Example 3 in “User-Defined Inference Rules”.)
This section describes user-defined macros, shows how to use a macro, and discusses the macros that have special meaning for NMAKE. It ends by discussing macro substitutions, inherited macros, and precedence rules.
