Automake's implicit copying semantics means that many problems can be
worked around by simply adding some
make targets and rules to
`Makefile.in'. Automake will ignore these additions.
There are some caveats to doing this. Although you can overload a target already used by Automake, it is often inadvisable, particularly in the topmost directory of a package with subdirectories. However, various useful targets have a `-local' version you can specify in your `Makefile.in'. Automake will supplement the standard target with these user-supplied targets.
The targets that support a local version are
uninstall, and the various
maintainer-clean). Note that there are no
uninstall-data-local targets; just
uninstall-local. It doesn't make sense to uninstall just
data or just executables.
For instance, here is one way to install a file in `/etc':
install-data-local: $(INSTALL_DATA) $(srcdir)/afile /etc/afile
Some targets also have a way to run another target, called a hook,
after their work is done. The hook is named after the principal target,
with `-hook' appended. The targets allowing hooks are
For instance, here is how to create a hard link to an installed program:
install-exec-hook: ln $(bindir)/program $(bindir)/proglink
