Control Macros
make defines a number of control macros that control make’s behavior. When there
are several ways of doing the same thing, control macros are usually the best. A
control macro that has the same function as a special target or attribute also has
the same name.
Macros that are said to be defined internally are automatically created by make and
can be used with the usual $(name) construct. For example, $(PWD) can be used to
obtain the current directory name.
Recognized control macros are:
DIRSEPSTR
Contains the characters used to separate parts in a pathname and can be
set by the user. make uses the first character in this string to build
pathnames when necessary.
.EPILOG
If assigned a nonnull value, the .EPILOG attribute is given to every target.
GROUPFLAGS
Specifies option flags to pass to GROUPSHELL when make invokes it to run a
group recipe.
GROUPSHELL
Gives the pathname of the command interpreter (shell) that make calls to
process group recipes.
GROUPSUFFIX
Specifies a string for make to use as a suffix when creating group recipe
files to be run by the command interpreter.
.IGNORE
If this is assigned a nonnull value, make assigns the .IGNORE attribute to
every target.
INCDEPTH
This is the current depth of makefile inclusion. It is set internally.
MAKE This is set by the startup file and can be changed by the user. The standard
startup file defines it as:
$(MAKECMD) $(MFLAGS)
The MAKE macro is not used by make itself, but the string $(MAKE) is
recognized when using the –n option for single-line recipes.
MAKECMD
This is the name with which make was invoked.
MAKEDIR
This is the full pathname of the initial directory in which make began
execution.
MAKEFLAGS
The MAKEFLAGS macro contains all the options (flags) and macros specified
in the MAKEFLAGS environment variable plus all of the options and
macros specified on the command line, with the following exceptions.
v Specifying –c, –f, or –p in the environment variable results in an error
make
v These same options specified on the command line do not appear in the
MAKEFLAGS macro.
