GNU Info
(make.info)Standard Targets
Standard Targets for Users
==========================
All GNU programs should have the following targets in their
Makefiles:
`all'
Compile the entire program. This should be the default target.
This target need not rebuild any documentation files; Info files
should normally be included in the distribution, and DVI files
should be made only when explicitly asked for.
By default, the Make rules should compile and link with `-g', so
that executable programs have debugging symbols. Users who don't
mind being helpless can strip the executables later if they wish.
`install'
Compile the program and copy the executables, libraries, and so on
to the file names where they should reside for actual use. If
there is a simple test to verify that a program is properly
installed, this target should run that test.
Do not strip executables when installing them. Devil-may-care
users can use the `install-strip' target to do that.
If possible, write the `install' target rule so that it does not
modify anything in the directory where the program was built,
provided `make all' has just been done. This is convenient for
building the program under one user name and installing it under
another.
The commands should create all the directories in which files are
to be installed, if they don't already exist. This includes the
directories specified as the values of the variables `prefix' and
`exec_prefix', as well as all subdirectories that are needed. One
way to do this is by means of an `installdirs' target as described
below.
Use `-' before any command for installing a man page, so that
`make' will ignore any errors. This is in case there are systems
that don't have the Unix man page documentation system installed.
The way to install Info files is to copy them into `$(infodir)'
with `$(INSTALL_DATA)' (Note: Command Variables), and then run
the `install-info' program if it is present. `install-info' is a
program that edits the Info `dir' file to add or update the menu
entry for the given Info file; it is part of the Texinfo package.
Here is a sample rule to install an Info file:
$(DESTDIR)$(infodir)/foo.info: foo.info
$(POST_INSTALL)
# There may be a newer info file in . than in srcdir.
-if test -f foo.info; then d=.; \
else d=$(srcdir); fi; \
$(INSTALL_DATA) $$d/foo.info $(DESTDIR)$@; \
# Run install-info only if it exists.
# Use `if' instead of just prepending `-' to the
# line so we notice real errors from install-info.
# We use `$(SHELL) -c' because some shells do not
# fail gracefully when there is an unknown command.
if $(SHELL) -c 'install-info --version' \
>/dev/null 2>&1; then \
install-info --dir-file=$(DESTDIR)$(infodir)/dir \
$(DESTDIR)$(infodir)/foo.info; \
else true; fi
When writing the `install' target, you must classify all the
commands into three categories: normal ones, "pre-installation"
commands and "post-installation" commands. Note: Install Command
Categories.
`uninstall'
Delete all the installed files--the copies that the `install'
target creates.
This rule should not modify the directories where compilation is
done, only the directories where files are installed.
The uninstallation commands are divided into three categories,
just like the installation commands. Note: Install Command
Categories.
`install-strip'
Like `install', but strip the executable files while installing
them. In many cases, the definition of this target can be very
simple:
install-strip:
$(MAKE) INSTALL_PROGRAM='$(INSTALL_PROGRAM) -s' \
install
Normally we do not recommend stripping an executable unless you
are sure the program has no bugs. However, it can be reasonable
to install a stripped executable for actual execution while saving
the unstripped executable elsewhere in case there is a bug.
`clean'
Delete all files from the current directory that are normally
created by building the program. Don't delete the files that
record the configuration. Also preserve files that could be made
by building, but normally aren't because the distribution comes
with them.
Delete `.dvi' files here if they are not part of the distribution.
`distclean'
Delete all files from the current directory that are created by
configuring or building the program. If you have unpacked the
source and built the program without creating any other files,
`make distclean' should leave only the files that were in the
distribution.
`mostlyclean'
Like `clean', but may refrain from deleting a few files that people
normally don't want to recompile. For example, the `mostlyclean'
target for GCC does not delete `libgcc.a', because recompiling it
is rarely necessary and takes a lot of time.
`maintainer-clean'
Delete almost everything from the current directory that can be
reconstructed with this Makefile. This typically includes
everything deleted by `distclean', plus more: C source files
produced by Bison, tags tables, Info files, and so on.
The reason we say "almost everything" is that running the command
`make maintainer-clean' should not delete `configure' even if
`configure' can be remade using a rule in the Makefile. More
generally, `make maintainer-clean' should not delete anything that
needs to exist in order to run `configure' and then begin to build
the program. This is the only exception; `maintainer-clean' should
delete everything else that can be rebuilt.
The `maintainer-clean' target is intended to be used by a
maintainer of the package, not by ordinary users. You may need
special tools to reconstruct some of the files that `make
maintainer-clean' deletes. Since these files are normally
included in the distribution, we don't take care to make them easy
to reconstruct. If you find you need to unpack the full
distribution again, don't blame us.
To help make users aware of this, the commands for the special
`maintainer-clean' target should start with these two:
@echo 'This command is intended for maintainers to use; it'
@echo 'deletes files that may need special tools to rebuild.'
`TAGS'
Update a tags table for this program.
`info'
Generate any Info files needed. The best way to write the rules
is as follows:
info: foo.info
foo.info: foo.texi chap1.texi chap2.texi
$(MAKEINFO) $(srcdir)/foo.texi
You must define the variable `MAKEINFO' in the Makefile. It should
run the `makeinfo' program, which is part of the Texinfo
distribution.
Normally a GNU distribution comes with Info files, and that means
the Info files are present in the source directory. Therefore,
the Make rule for an info file should update it in the source
directory. When users build the package, ordinarily Make will not
update the Info files because they will already be up to date.
`dvi'
Generate DVI files for all Texinfo documentation. For example:
dvi: foo.dvi
foo.dvi: foo.texi chap1.texi chap2.texi
$(TEXI2DVI) $(srcdir)/foo.texi
You must define the variable `TEXI2DVI' in the Makefile. It should
run the program `texi2dvi', which is part of the Texinfo
distribution.(1) Alternatively, write just the dependencies, and
allow GNU `make' to provide the command.
`dist'
Create a distribution tar file for this program. The tar file
should be set up so that the file names in the tar file start with
a subdirectory name which is the name of the package it is a
distribution for. This name can include the version number.
For example, the distribution tar file of GCC version 1.40 unpacks
into a subdirectory named `gcc-1.40'.
The easiest way to do this is to create a subdirectory
appropriately named, use `ln' or `cp' to install the proper files
in it, and then `tar' that subdirectory.
Compress the tar file file with `gzip'. For example, the actual
distribution file for GCC version 1.40 is called `gcc-1.40.tar.gz'.
The `dist' target should explicitly depend on all non-source files
that are in the distribution, to make sure they are up to date in
the distribution. Note: Making Releases.
`check'
Perform self-tests (if any). The user must build the program
before running the tests, but need not install the program; you
should write the self-tests so that they work when the program is
built but not installed.
The following targets are suggested as conventional names, for
programs in which they are useful.
`installcheck'
Perform installation tests (if any). The user must build and
install the program before running the tests. You should not
assume that `$(bindir)' is in the search path.
`installdirs'
It's useful to add a target named `installdirs' to create the
directories where files are installed, and their parent
directories. There is a script called `mkinstalldirs' which is
convenient for this; you can find it in the Texinfo package. You
can use a rule like this:
# Make sure all installation directories (e.g. $(bindir))
# actually exist by making them if necessary.
installdirs: mkinstalldirs
$(srcdir)/mkinstalldirs $(bindir) $(datadir) \
$(libdir) $(infodir) \
$(mandir)
This rule should not modify the directories where compilation is
done. It should do nothing but create installation directories.
