22 # Each language makefile fragment must provide the following targets:
24 # foo.all.cross, foo.start.encap, foo.rest.encap,
25 # foo.install-common, foo.install-man, foo.install-info, foo.install-pdf,
26 # foo.install-html, foo.info, foo.dvi, foo.pdf, foo.html, foo.uninstall,
27 # foo.mostlyclean, foo.clean, foo.distclean,
28 # foo.maintainer-clean, foo.stage1, foo.stage2, foo.stage3, foo.stage4
30 # where `foo' is the name of the language.
32 # It should also provide rules for:
34 # - making any compiler driver (eg: g++)
35 # - the compiler proper (eg: cc1plus)
36 # - define the names for selecting the language in LANGUAGES.
39 # Define the names for selecting Objective-C in LANGUAGES.
