Noeud:Special Targets, Noeud « Next »:Make Conditionals, Noeud « Previous »:Shell Commands, Noeud « Up »:GNU Make
Different implementations of Make provide varying numbers of
special targets: GNU Make itself has a particularly
impressive array of special targets, which are described exhaustively in
the documention installed along with the GNU Make binary. However,
in conjunction with Automake (voir Automake), none are actually
explicitly required. We discuss them here because if you decide not to
use Automake for some reason, you will need to use them - and,
besides, the equivalent features in Automake are easier to understand if
you have a good grasp of what is happening in the Makefile
s it
generates.
In the next two subsections we discuss .SUFFIXES
and
.PHONY
as a useful and representative subset of the special
targets supported by all incarnations of Make.
