Special Targets

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 Makefiles 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.
