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.

97 ##################################################################
98 # GNU Standard targets
100 # Every Makefile should define the following targets
103 # Compile the entire program. This should be the default target.
104 # This target need not rebuild any documentation files; Info files
105 # should normally be included in the distribution, and DVI files
106 # should be made only when explicitly asked for.
109 # Compile the program and copy the executables, libraries, and so on
110 # to the file names where they should reside for actual use. If
111 # there is a simple test to verify that a program is properly
112 # installed, this target should run that test.
114 # The commands should create all the directories in which files are
115 # to be installed, if they don't already exist. This includes the
116 # directories specified as the values of the variables prefix and
117 # exec_prefix , as well as all subdirectories that are needed. One
118 # way to do this is by means of an installdirs target as described
121 # Use `-' before any command for installing a man page, so that make
122 # will ignore any errors. This is in case there are systems that
123 # don't have the Unix man page documentation system installed.
125 # The way to install Info files is to copy them into `$(infodir)'
126 # with $(INSTALL_DATA) (see Command Variables), and then run the
127 # install-info program if it is present. install-info is a script
128 # that edits the Info `dir' file to add or update the menu entry for
129 # the given Info file; it will be part of the Texinfo package. Here
130 # is a sample rule to install an Info file:
132 # $(infodir)/foo.info: foo.info # There may be a newer info
133 # file in . than in srcdir.
134 # -if test -f foo.info; then d=.; \
135 # else d=$(srcdir); fi; \ $(INSTALL_DATA)
136 # $$d/foo.info $@; \ # Run install-info only if it
137 # exists. # Use `if' instead of just prepending `-' to the
138 # # line so we notice real errors from install-info. # We
139 # use `$(SHELL) -c' because some shells do not # fail
140 # gracefully when there is an unknown command.
141 # if $(SHELL) -c 'install-info --version' \
142 # >/dev/null 2>&1; then \ install-info
143 # --infodir=$(infodir) $$d/foo.info; \ else true;
147 # Delete all the installed files that the `install' target would
148 # create (but not the noninstalled files such as `make all' would
153 # Delete all files from the current directory that are normally
154 # created by building the program. Don't delete the files that
155 # record the configuration. Also preserve files that could be made
156 # by building, but normally aren't because the distribution comes
159 # Delete `.dvi' files here if they are not part of the
163 # Delete all files from the current directory that are created by
164 # configuring or building the program. If you have unpacked the
165 # source and built the program without creating any other files,
166 # `make distclean' should leave only the files that were in the
170 # Like `clean', but may refrain from deleting a few files that
171 # people normally don't want to recompile. For example, the
172 # `mostlyclean' target for GCC does not delete `libgcc.a', because
173 # recompiling it is rarely necessary and takes a lot of time.
176 # Delete everything from the current directory that can be
177 # reconstructed with this Makefile. This typically includes
178 # everything deleted by distclean , plus more: C source files
179 # produced by Bison, tags tables, Info files, and so on.
181 # One exception, however: `make maintainer-clean' should not delete
182 # `configure' even if `configure' can be remade using a rule in the
183 # Makefile. More generally, `make maintainer-clean' should not delete
184 # anything that needs to exist in order to run `configure' and then
185 # begin to build the program.
188 # Update a tags table for this program.
191 # Generate any Info files needed. The best way to write the rules is
196 # foo.info: foo.texi chap1.texi chap2.texi
197 # $(MAKEINFO) $(srcdir)/foo.texi
199 # You must define the variable MAKEINFO in the Makefile. It should
200 # run the makeinfo program, which is part of the Texinfo
204 # Generate DVI files for all TeXinfo documentation. For example:
208 # foo.dvi: foo.texi chap1.texi chap2.texi
209 # $(TEXI2DVI) $(srcdir)/foo.texi
211 # You must define the variable TEXI2DVI in the Makefile. It should
212 # run the program texi2dvi , which is part of the Texinfo
213 # distribution. Alternatively, write just the dependencies, and
214 # allow GNU Make to provide the command.
216 # ps is a FPtools addition for Postscript files
218 # `dist' `binary-dist'
219 # Create a distribution tar file for this program. The tar file
220 # should be set up so that the file names in the tar file start with
221 # a subdirectory name which is the name of the package it is a
222 # distribution for. This name can include the version number.
224 # For example, the distribution tar file of GCC version 1.40 unpacks
225 # into a subdirectory named `gcc-1.40'.
227 # The easiest way to do this is to create a subdirectory
228 # appropriately named, use ln or cp to install the proper files in
229 # it, and then tar that subdirectory.
231 # The dist target should explicitly depend on all non-source files
232 # that are in the distribution, to make sure they are up to date in
233 # the distribution. See Making Releases.
235 # binary-dist is an FPtools addition for binary distributions
238 # Perform self-tests (if any). The user must build the program
239 # before running the tests, but need not install the program; you
240 # should write the self-tests so that they work when the program is
241 # built but not installed.
243 # The following targets are suggested as conventional names, for programs
244 # in which they are useful.
247 # Perform installation tests (if any). The user must build and
248 # install the program before running the tests. You should not
249 # assume that `$(bindir)' is in the search path.
252 # It's useful to add a target named `installdirs' to create the
253 # directories where files are installed, and their parent
254 # directories. There is a script called `mkinstalldirs' which is
255 # convenient for this; find it in the Texinfo package.
256 # (FPTOOLS: we don't use the suggested script, but rather the
257 # mkdirhier script in glafp_utils -- SOF)
