16 # 2. GNU standard targets
18 # install* uninstall installcheck installdirs
19 # clean* distclean* mostlyclean* maintainer-clean*
25 # 3. Some of the above targets have a version that
26 # recursively invokes that target in sub-directories.
27 # This relies on the importing Makefile setting SUBDIRS
29 # The recursive targets are marked with a * above

38 # FPtools standard targets
42 # The depend target has to cope with a set of files that may have
43 # different ways of computing their dependencies, i.e., a Haskell
44 # module's dependencies are computed differently from C files.
46 # Note that we don't compute dependencies automatically, i.e., have the
47 # .depend file be a target that is dependent on the Haskell+C sources,
48 # and then have the `depend' target depend on `.depend'. The reason for
49 # this is that when GNU make is processing the `include .depend' statement
50 # it records .depend as being a Makefile. Before doing any other processing,
51 # `make' will try to check to see if the Makefiles are up-to-date. And,
52 # surprisingly enough, .depend has a rule for it, so if any of the source
53 # files change, it will be invoked, *regardless* of what target you're making.
55 # So, for now, the dependencies has to be re-computed manually via `make depend'
56 # whenever a module changes its set of imports. Doing what was outlined above
57 # is only a small optimisation anyway, it would avoid the recomputation of
58 # dependencies if the .depend file was newer than any of the source modules.
62 # Compiler produced files that are targets of the source's imports.

92 ##################################################################
93 # GNU Standard targets
95 # Every Makefile should define the following targets
98 # Compile the entire program. This should be the default target.
99 # This target need not rebuild any documentation files; Info files
100 # should normally be included in the distribution, and DVI files
101 # should be made only when explicitly asked for.
104 # Compile the program and copy the executables, libraries, and so on
105 # to the file names where they should reside for actual use. If
106 # there is a simple test to verify that a program is properly
107 # installed, this target should run that test.
109 # The commands should create all the directories in which files are
110 # to be installed, if they don't already exist. This includes the
111 # directories specified as the values of the variables prefix and
112 # exec_prefix , as well as all subdirectories that are needed. One
113 # way to do this is by means of an installdirs target as described
116 # Use `-' before any command for installing a man page, so that make
117 # will ignore any errors. This is in case there are systems that
118 # don't have the Unix man page documentation system installed.
120 # The way to install Info files is to copy them into `$(infodir)'
121 # with $(INSTALL_DATA) (see Command Variables), and then run the
122 # install-info program if it is present. install-info is a script
123 # that edits the Info `dir' file to add or update the menu entry for
124 # the given Info file; it will be part of the Texinfo package. Here
125 # is a sample rule to install an Info file:
127 # $(infodir)/foo.info: foo.info # There may be a newer info
128 # file in . than in srcdir.
129 # -if test -f foo.info; then d=.; \
130 # else d=$(srcdir); fi; \ $(INSTALL_DATA)
131 # $$d/foo.info $@; \ # Run install-info only if it
132 # exists. # Use `if' instead of just prepending `-' to the
133 # # line so we notice real errors from install-info. # We
134 # use `$(SHELL) -c' because some shells do not # fail
135 # gracefully when there is an unknown command.
136 # if $(SHELL) -c 'install-info --version' \
137 # >/dev/null 2>&1; then \ install-info
138 # --infodir=$(infodir) $$d/foo.info; \ else true;
142 # Delete all the installed files that the `install' target would
143 # create (but not the noninstalled files such as `make all' would
148 # Delete all files from the current directory that are normally
149 # created by building the program. Don't delete the files that
150 # record the configuration. Also preserve files that could be made
151 # by building, but normally aren't because the distribution comes
154 # Delete `.dvi' files here if they are not part of the
158 # Delete all files from the current directory that are created by
159 # configuring or building the program. If you have unpacked the
160 # source and built the program without creating any other files,
161 # `make distclean' should leave only the files that were in the
165 # Like `clean', but may refrain from deleting a few files that
166 # people normally don't want to recompile. For example, the
167 # `mostlyclean' target for GCC does not delete `libgcc.a', because
168 # recompiling it is rarely necessary and takes a lot of time.
171 # Delete everything from the current directory that can be
172 # reconstructed with this Makefile. This typically includes
173 # everything deleted by distclean , plus more: C source files
174 # produced by Bison, tags tables, Info files, and so on.
176 # One exception, however: `make maintainer-clean' should not delete
177 # `configure' even if `configure' can be remade using a rule in the
178 # Makefile. More generally, `make maintainer-clean' should not delete
179 # anything that needs to exist in order to run `configure' and then
180 # begin to build the program.
183 # Update a tags table for this program.
186 # Generate any Info files needed. The best way to write the rules is
191 # foo.info: foo.texi chap1.texi chap2.texi
192 # $(MAKEINFO) $(srcdir)/foo.texi
194 # You must define the variable MAKEINFO in the Makefile. It should
195 # run the makeinfo program, which is part of the Texinfo
199 # Generate DVI files for all TeXinfo documentation. For example:
203 # foo.dvi: foo.texi chap1.texi chap2.texi
204 # $(TEXI2DVI) $(srcdir)/foo.texi
206 # You must define the variable TEXI2DVI in the Makefile. It should
207 # run the program texi2dvi , which is part of the Texinfo
208 # distribution. Alternatively, write just the dependencies, and
209 # allow GNU Make to provide the command.
211 # ps is a FPtools addition for Postscript files
213 # `dist' `binary-dist'
214 # Create a distribution tar file for this program. The tar file
215 # should be set up so that the file names in the tar file start with
216 # a subdirectory name which is the name of the package it is a
217 # distribution for. This name can include the version number.
219 # For example, the distribution tar file of GCC version 1.40 unpacks
220 # into a subdirectory named `gcc-1.40'.
222 # The easiest way to do this is to create a subdirectory
223 # appropriately named, use ln or cp to install the proper files in
224 # it, and then tar that subdirectory.
226 # The dist target should explicitly depend on all non-source files
227 # that are in the distribution, to make sure they are up to date in
228 # the distribution. See Making Releases.
230 # binary-dist is an FPtools addition for binary distributions
233 # Perform self-tests (if any). The user must build the program
234 # before running the tests, but need not install the program; you
235 # should write the self-tests so that they work when the program is
236 # built but not installed.
238 # The following targets are suggested as conventional names, for programs
239 # in which they are useful.
242 # Perform installation tests (if any). The user must build and
243 # install the program before running the tests. You should not
244 # assume that `$(bindir)' is in the search path.
247 # It's useful to add a target named `installdirs' to create the
248 # directories where files are installed, and their parent
249 # directories. There is a script called `mkinstalldirs' which is
250 # convenient for this; find it in the Texinfo package.
251 # (FPTOOLS: we use a close relative of the suggested script, situated
252 # in glafp-utils/mkdirhier -- SOF)

871 # The ways setup requires the following variables to be set:
873 # Expects: $(WAYS) the possible "way" strings to one of
874 # which $(way) will be set
877 # So how does $(way) ever get set to anything? Answer, we recursively
878 # invoke make, setting $(way) on the command line.
879 # When do we do this recursion? Answer: whenever the programmer
880 # asks make to make a target that involves a way suffix.
881 # We must remember *not* to recurse again; but that's easy: we
882 # just see if $(way) is set:
886 # If $(WAYS) = p mc, then WAY_TARGETS expands to
887 # %.p_lhs %.p_hs %.p_o ... %.mc_lhs %.p_hs ...
888 # and OTHER_WAY_TARGETS to
889 # %_p.a %_p %_mc.a %_mc
890 # where the suffixes are from $(SUFFIXES)
892 # We have to treat libraries and "other" targets differently,

928 # Here are the diabolically clever rules that
930 # (a) for each "recursive target" <t>
931 # propagates "make <t>" to directories in SUBDIRS
933 # (b) when SUBDIRS is empty,
934 # for each "multi-way-target" <t>
935 # calls "make -way=w <t>" for each w in $(WAYS)
937 # This has the effect of making the standard target
938 # in each of the specified ways (as well as in the normal way
940 # Controlling variables
941 # WAYS = extra (beyond the normal way) ways to build things in
942 # SUBDIRS = subdirectories to recurse into
944 # No ways, so iterate over the SUBDIRS
946 # note about recursively invoking make: we'd like make to drop all the
947 # way back to the top level if it fails in any of the
948 # sub(sub-...)directories. This is done by setting the -e flag to the
949 # shell during the loop, which causes an immediate failure if any of
950 # the shell commands fail.
952 # One exception: if the user gave the -i or -k flag to make in the
953 # first place, we'd like to reverse this behaviour. So we check for
954 # these flags, and set the -e flag appropriately. NOTE: watch out for
955 # the --no-print-directory flag which is passed to recursive
956 # invocations of make.
958 # NOTE: Truly weird use of exit below to stop the for loop dead in
959 # its tracks should any of the sub-makes fail. By my reckoning,
960 # "cmd || exit $?" should be equivalent to "cmd"
