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