For target files that already exist, Make determines which components need to be rebuilt by looking at the dependencies described in the makefile. Commands are generated to rebuild components that depend on files that are newer than the target. You can also specify a makefile by using -f . Otherwise Make uses the MakeFile file located in the current directory. Make generates MPW Shell commands to build or rebuild the files of the target.
Targets are commonly files but can be artificial names or variables.
If you do not specify any targets, Make generates commands to build the target on the left side of the first dependency rule in the makefile. Defines the variable name as having the given value value . Variables defined from the command line take precedence over definitions of the same variable in the makefile. Thus definitions in the makefiles act as defaults that you can override from the command line. Generates commands to rebuild all components of the specified targets, regardless of whether they are out of date.
