Introduction
************
Automake is a tool for automatically generating `Makefile.in's from
files called `Makefile.am'. The `Makefile.am' is basically a series of
`make' macro definitions (with rules being thrown in occasionally).
The generated `Makefile.in's are compliant with the GNU Makefile
standards.
The GNU Makefile Standards Document (*note Makefile Conventions:
(standards.info)Makefile Conventions.) is long, complicated, and
subject to change. The goal of Automake is to remove the burden of
Makefile maintenance from the back of the individual GNU maintainer
(and put it on the back of the Automake maintainer).
The typical Automake input files is simply a series of macro
definitions. Each such file is processed to create a `Makefile.in'.
There should generally be one `Makefile.am' per directory of a project.
Automake does constrain a project in certain ways; for instance it
assumes that the project uses Autoconf (*note The Autoconf Manual:
(autoconf.info)Top.), and enforces certain restrictions on the
`configure.in' contents.
`Automake' requires `perl' in order to generate the `Makefile.in's.
However, the distributions created by Automake are fully GNU
standards-compliant, and do not require `perl' in order to be built.

Creating a `Makefile.in'
************************
To create all the `Makefile.in's for a package, run the `automake'
program in the top level directory, with no arguments. `automake' will
automatically find each appropriate `Makefile.am' (by scanning
`configure.in'; *note configure::.) and generate the corresponding
`Makefile.in'.
You can optionally give `automake' an argument; `.am' is appended to
the argument and the result is used as the name of the input file.
This feature is generally only used to automatically rebuild an
out-of-date `Makefile.in'. Note that `automake' must always be run
from the topmost directory of a project, even if being used to
regenerate the `Makefile.in' in some subdirectory. This is necessary
because `automake' must scan `configure.in', and because `automake'
uses the knowledge that a `Makefile.in' is in a subdirectory to change
its behavior in some cases.
`automake' accepts the following options:
`--amdir=DIR'
Look for Automake data files in directory DIR instead of in the
installation directory. This is typically used for debugging.
`--foreign'
An alias for `--strictness=foreign'.
`--gnits'
An alias for `--strictness=gnits'.
`--gnu'
An alias for `--strictness=gnu'.
`--help'
Print a summary of the command line options and exit.
`--include-deps'
Include all automatically generated dependency information (*note
Dependencies::.) in the generated `Makefile.in'. This is
generally done when making a distribution; see *Note Dist::.
`--add-missing'
Automake requires certain common files to exist in certain
situations; for instance `config.guess' is required if
`configure.in' runs `AC_CANONICAL_HOST'. Automake is distributed
with several of these files; this option will cause the missing
ones to be automatically added to the package, whenever possible.
`--output-dir=DIR'
Put the generated `Makefile.in' in the directory DIR. Ordinarily
each `Makefile.in' is created in the directory of the
corresponding `Makefile.am'. This option is used when making
distributions.
`--strictness=LEVEL'
Set the global strictness to LEVEL; this can be overridden in each
`Makefile.am' if required. *Note Generalities:: for more
information.
`--verbose'
Cause Automake to print information about which files are being
read or created.
`--version'
Print the version number of Automake and exit.

General ideas
*************
Depth
=====
`automake' supports three kinds of directory hierarchy: "flat",
"shallow", and "deep".
A "flat" package is one in which all the files are in a single
directory. The `Makefile.am' for such a package by definition lacks a
`SUBDIRS' macro. An example of such a package is `termutils'.
A "deep" package is one in which all the source lies in
subdirectories; the top level directory contains mainly configuration
information. GNU cpio is a good example of such a package, as is GNU
`tar'. The top level `Makefile.am' for a deep package will contain a
`SUBDIRS' macro, but no other macros to define objects which are built.
A "shallow" package is one in which the primary source resides in
the top-level directory, while various parts (typically libraries)
reside in subdirectories. `automake' is one such package (as is GNU
`make', which does not currently use `automake').
Strictness
==========
While Automake is intended to be used by maintainers of GNU
packages, it does make some effort to accomodate those who wish to use
it, but do not want to use all the GNU conventions.
To this end, Automake supports three levels of "strictness" - the
strictness indicating how stringently Automake should check standards
conformance.
The valid strictness levels are:
`foreign'
Automake will check for only those things which are absolutely
required for proper operations. For instance, whereas GNU
standards dictate the existence of a `NEWS' file, it will not be
required in this mode. The name comes from the fact that Automake
is intended to be used for GNU programs; these relaxed rules are
not the standard mode of operation.
`gnu'
Automake will check - as much as possible - for compliance to the
GNU standards for packages. This is the default.
`gnits'
Automake will check for compliance to the as-yet-unwritten GNITS
standards. These are based on the GNU standards, but are even more
detailed. Unless you are a GNITS standards contributor, it is
recommended that you avoid this option until such time as the GNITS
standard is actually published.
The Uniform Naming Scheme
=========================
Automake variables generally follow a uniform naming scheme that
makes it easy to decide how programs (and other derived objects) are
built, and how they are installed. This scheme also supports
`configure' time determination of what should be built.
At `make' time, certain variables are used to determine which
objects are to be built. These variables are called "primary"
variables. For instance, the primary variable `PROGRAMS' holds a list
of programs which are to be compiled and linked.
A different set of variables is used to decide where the built
objects should be installed. These variables are named after the
primary variables, but have a prefix indicating which standard
directory should be used as the installation directory. The standard
directory names are given in the GNU standards (*note Directory
Variables: (standards.info)Directory Variables.). `automake' extends
this list with `pkglibdir', `pkgincludedir', and `pkgdatadir'; these
are the same as the non-`pkg' versions, but with `@PACKAGE@' appended.
For each primary, there is one additional variable named by
prepending `EXTRA_' to the primary name. This variable is used to list
objects which may or may not be built, depending on what `configure'
decides. This variable is required because Automake must know the
entire list of objects to be built in order to generate a `Makefile.in'
that will work in all cases.
For instance, `cpio' decides at configure time which programs are
built. Some of the programs are installed in `bindir', and some are
installed in `sbindir':
EXTRA_PROGRAMS = mt rmt
bin_PROGRAMS = cpio pax
sbin_PROGRAMS = @PROGRAMS@
Defining a primary variable is an error.
Note that the common `dir' suffix is left off when constructing the
variable names; thus one writes `bin_PROGRAMS' and not
`bindir_PROGRAMS'.
Not every sort of object can be installed in every directory.
Automake will flag those attempts it finds in error. Automake will
also diagnose obvious misspellings in directory names.
Sometimes the standard directories - even as augmented by Automake -
are not enough. In particular it is sometimes useful, for clarity, to
install objects in a subdirectory of some predefined directory. To this
end, Automake allows you to extend the list of possible installation
directories. A given prefix (eg `zar') is valid if a variable of the
same name with `dir' appended is defined (eg `zardir').
For instance, until HTML support is part of Automake, you could use
this to install raw HTML documentation:
htmldir = $(prefix)/html
html_DATA = automake.html
The special prefix `noinst' indicates that the objects in question
should not be installed at all.
The special prefix `check' indicates that the objects in question
should not be built until the `make check' command is run.
Possible primary names are `PROGRAMS', `LIBRARIES', `SCRIPTS',
`DATA', `HEADERS', `MANS', and `TEXINFOS'.
General Operation
=================
Automake essentially works by reading a `Makefile.am' and generating
a `Makefile.in'. The macro definitions and targets in the
`Makefile.am' are copied into the generated file.
Automake tries to group comments with adjoining targets (or variable
definitions) in an intelligent way.
A target defined in `Makefile.am' generally overrides any such
target of a similar name that would be automatically generated by
`automake'. Although this is a supported feature, it is generally best
to avoid making use of it, as sometimes the generated rules are very
particular.
Automake also allows a form of comment which is *not* copied into
the output; all lines beginning with `##' are completely ignored by
Automake.
It is customary to make the first line of `Makefile.am' read:
## Process this file with automake to produce Makefile.in
File: automake.info, Node: configure, Next: Top level, Prev: Generalities, Up: Top
Scanning `configure.in'
***********************
Automake requires certain variables to be defined and certain macros
to be used in the package `configure.in'.
One such requirement is that `configure.in' must define the
variables `PACKAGE' and `VERSION' with `AC_SUBST'. `PACKAGE' should be
the name of the package as it appears when bundled for distribution.
For instance, Automake definees `PACKAGE' to be `automake'. `VERSION'
should be the version number of the release that is being developed.
We recommend that you make `configure.in' the only place in your
package where the version number is defined; this makes releases
simpler.
Automake requires the use of the macro `AC_ARG_PROGRAM' if a program
or script is installed.
If your package is not a flat distribution, Automake requires the
use of `AC_PROG_MAKE_SET'.
Automake will also recognize the use of certain macros and tailor the
generated `Makefile.in' appropriately. Currently recognized macros and
their effects are:
`AC_CONFIG_HEADER'
Automake will generate rules to automatically regenerate the config
header. If you do use this macro, you must create the file
`stamp-h.in'. It can be empty. Also, the `AC_OUTPUT' command in
`configure.in' must create `stamp-h', eg:
AC_OUTPUT(Makefile, [test -z "$CONFIG_HEADERS" || echo timestamp > stamp-h])
`AC_CONFIG_AUX_DIR'
Automake will look for various helper scripts, such as
`mkinstalldirs', in the directory named in this macro invocation.
If not seen, the scripts are looked for in their "standard"
locations (either the top source directory, or in the source
directory corresponding to the current `Makefile.am', whichever is
appropriate).
`AC_OUTPUT'
Automake uses this to determine which files to create.
`AC_PATH_XTRA'
Automake will insert definitions for the variables defined by
`AC_PATH_XTRA' into each `Makefile.in' that builds a C program or
library.
`AC_CANONICAL_HOST'
`AC_CANONICAL_SYSTEM'
`AC_CHECK_TOOL'
Automake will ensure that `config.guess' and `config.sub' exist.
`AC_FUNC_ALLOCA'
`AC_FUNC_GETLOADAVG'
`AC_FUNC_MEMCMP'
`AC_STRUCT_ST_BLOCKS'
`fp_FUNC_FNMATCH'
`AC_FUNC_FNMATCH'
`AC_REPLACE_FUNCS'
`AC_REPLACE_GNU_GETOPT'
Automake will ensure that the appropriate source files are part of
the distribution, and will ensure that the appropriate
dependencies are generated for these objects. *Note A Library::
for more information.
Automake will also detect statements which put `.o' files into
`LIBOBJS', and will treat these additional files in a similar way.
`AC_PROG_RANLIB'
This is required if any libraries are built in the package.
`AC_PROG_INSTALL'
`fp_PROG_INSTALL'
`fp_PROG_INSTALL' is required if any scripts (*note Scripts::.) are
installed by the package. Otherwise, `AC_PROG_INSTALL' is
required.
`gm_PROG_LIBTOOL'
`AC_PROG_LIBTOOL'
Automake will turn on processing for `libtool' (*note The Libtool
Manual: (libtool.info)Top.). This work is still preliminary.
`ALL_LINGUAS'
If Automake sees that this variable is set in `configure.in', it
will check the `po' directory to ensure that all the named `.po'
files exist, and that all the `.po' files that exist are named.
`fp_C_PROTOTYPES'
This is required when using automatic de-ANSI-fication, see *Note
ANSI::.
`ud_GNU_GETTEXT'
This macro is required for packages which use GNU gettext (FIXME
xref). It is distributed with gettext. Automake uses this macro
to ensure that the package meets some of gettext's requirements.
`jm_MAINTAINER_MODE'
This macro adds a `--enable-maintainer-mode' option to
`configure'. If this is used, `automake' will cause
"maintainer-only" rules to be turned off by default in the
generated `Makefile.in's.
The `fp_' macros are from Franc,ois Pinard and the `jm_' macro is
from Jim Meyering. Both sets are included with Automake. `automake'
will tell where the macros can be found if they are missing.
File: automake.info, Node: Top level, Next: Programs, Prev: configure, Up: Top
The top-level `Makefile.am'
***************************
In non-flat packages, the top level `Makefile.am' must tell Automake
which subdirectories are to be built. This is done via the `SUBDIRS'
variable.
The `SUBDIRS' macro holds a list of subdirectories in which building
of various sorts can occur. Many targets (eg `all') in the generated
`Makefile' will run both locally and in all specified subdirectories.
Note that the directories listed in `SUBDIRS' are not required to
contain `Makefile.am's; only `Makefile's (after configuration). This
allows inclusion of libraries from packages which do not use Automake
(such as `gettext').
In a deep package, the top-level `Makefile.am' is often very short.
For instance, here is the `Makefile.am' from the textutils distribution:
SUBDIRS = lib src doc man
EXTRA_DIST = @README_ALPHA@
`SUBDIRS' can contain configure substitutions (eg `@DIRS@');
Automake itself does not actually examine the contents of this variable.
If `SUBDIRS' is defined, then your `configure.in' must include
`AC_PROG_MAKE_SET'.

Building Programs and Libraries

easy to build C programs and libraries.

File: automake.info, Node: A Program, Next: A Library, Up: Programs
Building a program
==================
In a directory containing source that gets built into a program (as
opposed to a library), the `PROGRAMS' primary is used. Programs can be
installed in `bindir', `sbindir', `libexecdir', `pkglibdir', or not at
all.
For instance:
bin_PROGRAMS = hello
In this simple case, the resulting `Makefile.in' will contain code
to generate a program named `hello'. The variable `hello_SOURCES' is
used to specify which source files get built into an executable:
hello_SOURCES = hello.c
This causes `hello.c' to be compiled into `hello.o', and then linked
to produce `hello'.
If `prog_SOURCES' is needed, but not specified, then it defaults to
the single file `prog.c'. Id est in the example above, the definition
of `hello_SOURCES' is actually redundant.
Multiple programs can be built in a single directory. Multiple
programs can share a single source file. The source file must be
listed in each `_SOURCES' definition.
Header files listed in a `_SOURCES' definition will be ignored. Lex
(`.l') and yacc (`.y') files can also be listed; support for these
should work but is still preliminary.
Sometimes it is useful to determine the programs that are to be
built at configure time. For instance, GNU `cpio' only builts `mt' and
`rmt' under special circumstances.
In this case, you must notify `Automake' of all the programs that
can possibly be built, but at the same time cause the generated
`Makefile.in' to use the programs specified by `configure'. This is
done by having `configure' substitute values into each `_PROGRAMS'
definition, while listing all optionally built programs in
`EXTRA_PROGRAMS'.
If you need to link against libraries that are not found by
`configure', you can use `LDADD' to do so. This variable actually can
be used to add any options to the linker command line.
Sometimes, multiple programs are built in one directory but do not
share the same link-time requirements. In this case, you can use the
`PROG_LDADD' variable (where PROG is the name of the program as it
appears in some `_PROGRAMS' variable, and usually written in lowercase)
to override the global `LDADD'. (If this variable exists for a given
program, then that program is not linked using `LDADD'.)
For instance, in GNU cpio, `pax', `cpio', and `mt' are linked
against the library `libcpio.a'. However, `rmt' is built in the same
directory, and has no such link requirement. Also, `mt' and `rmt' are
only built on certain architectures. Here is what cpio's
`src/Makefile.am' looks like (abridged):
bin_PROGRAMS = cpio pax @MT@
libexec_PROGRAMS = @RMT@
EXTRA_PROGRAMS = mt rmt
LDADD = ../lib/libcpio.a @INTLLIBS@
rmt_LDADD =
cpio_SOURCES = ...
pax_SOURCES = ...
mt_SOURCES = ...
rmt_SOURCES = ...
It is also occasionally useful to have a program depend on some other
target which is not actually part of that program. This can be done
using the `prog_DEPENDENCIES' variable. Each program depends on the
contents of such a variable, but no further interpretation is done.
Since program names are rewritten into Makefile macro names, program
names must follow Makefile macro syntax. Sometimes it is useful to have
a program whose name does not follow such rules. In these cases,
Automake canonicalizes the program name. All characters in the name
except for letters, numbers, and the underscore are turned into
underscores when making macro references. Eg, if your program is named
`sniff-glue', you would use `sniff_glue_SOURCES', not
`sniff-glue_SOURCES'.
File: automake.info, Node: A Library, Next: ANSI, Prev: A Program, Up: Programs
Building a library
==================
Building a library is much like building a program. In this case,
the name of the primary is `LIBRARIES'. Libraries can be installed in
`libdir' or `pkglibdir'.
Each `_LIBRARIES' variable is a list of the base names of libraries
to be built. For instance to create a library named `libcpio.a', but
not install it, you would write:
noinst_LIBRARIES = cpio
The sources that go into a library are determined exactly as they are
for programs, via the `_SOURCES' variables. Note that programs and
libraries share a namespace, so one cannot have a program (`lob') and a
library (`liblob.a') with the same name in one directory.
Extra objects can be added to a library using the `library_LIBADD'
variable. This should be used for objects determined by `configure'.
Again from cpio:
cpio_LIBADD = @LIBOBJS@ @ALLOCA@
Note that Automake explicitly recognizes the use of `@LIBOBJS@' and
`@ALLOCA@' in the above example, and uses this information, plus the
list of `LIBOBJS' files derived from `configure.in' to automatically
include the appropriate source files in the distribution (*note
Dist::.). These source files are also automatically handled in the
dependency-tracking scheme, see *Note Dependencies::.
File: automake.info, Node: ANSI, Next: Dependencies, Prev: A Library, Up: Programs
Automatic de-ANSI-fication
==========================
Although the GNU standards prohibit it, some GNU programs are
written in ANSI C; see FIXME. This is possible because each source
file can be "de-ANSI-fied" before the actual compilation takes place.
If the `Makefile.am' variable `AUTOMAKE_OPTIONS' (*Note Options::)
contains the option `ansi2knr' then code to handle de-ANSI-fication is
inserted into the generated `Makefile.in'.
This causes each source file to be treated as ANSI C. If an ANSI C
compiler is available, it is used.
This support requires the source files `ansi2knr.c' and `ansi2knr.1'
to be in the same directory as the ANSI C source; these files are
distributed with Automake. Also, the package `configure.in' must call
the macro `fp_C_PROTOTYPES'.
File: automake.info, Node: Dependencies, Prev: ANSI, Up: Programs
Automatic dependency tracking
=============================
As a developer it is often painful to continually update the
`Makefile.in' whenever the include-file dependencies change in a
project. `automake' supplies a way to automatically track dependency
changes, and distribute the dependencies in the generated `Makefile.in'.
Currently this support requires the use of GNU `make' and `gcc'. It
might become possible in the future to supply a different dependency
generating program, if there is enough demand.
This mode is enabled by default if any C program or library is
defined in the current directory.
When you decide to make a distribution, the `dist' target will
re-run `automake' with the `--include-deps' option. This causes the
previously generated dependencies to be inserted into the generated
`Makefile.in', and thus into the distribution. `--include-deps' also
turns off inclusion of the dependency generation code.
This mode can be suppressed by putting `no-dependencies' in the
variable `AUTOMAKE_OPTIONS'.

Other Derived Objects
*********************
Automake can handle derived objects which are not C programs.
Sometimes the support for actually building such objects must be
explicitly supplied, but Automake will still automatically handle
installation and distribution.
* Menu:
* Scripts:: Executable scripts
* Headers:: Header files
* Data:: Architecture-independent data files
* Sources:: Derived sources
File: automake.info, Node: Scripts, Next: Headers, Up: Other objects
Executable Scripts
==================
It is possible to define and install programs which are scripts.
Such programs are listed using the `SCRIPTS' primary name. `automake'
doesn't define any dependencies for scripts; the `Makefile.am' should
include the appropriate rules.
`automake' does not assume that scripts are derived objects; such
objects are must be deleted by hand; see *Note Clean:: for more
information.
`automake' itself is a script that is generated at configure time
from `automake.in'. Here is how this is handled:
bin_SCRIPTS = automake
Since `automake' appears in the `AC_OUTPUT' macro, dependencies for
it are automatically generated.
Script objects can be installed in `bindir', `sbindir',
`libexecdir', or `pkgdatadir'.
File: automake.info, Node: Headers, Next: Data, Prev: Scripts, Up: Other objects
Header files
============
Header files are specified by the `HEADERS' family of variables.
Generally header files are not installed, so the `noinst_HEADERS'
variable will be the most used.
All header files must be listed somewhere; missing ones will not
appear in the distribution. Often it is most convenient to list
uninstalled headers with the rest of the sources for a program. *Note
A Program::.
Headers can be installed in `includedir', `oldincludedir', or
`pkgincludedir'.
File: automake.info, Node: Data, Next: Sources, Prev: Headers, Up: Other objects
Architecture-independent data files
===================================
Automake supports the installation of miscellaneous data files using
the `DATA' family of variables.
Such data can be installed in the directories `datadir',
`sysconfdir', `sharedstatedir', `localstatedir', or `pkgdatadir'.
All such data files are included in the distribution.
Here is how `autoconf' installs its auxiliary data files:
pkgdata_DATA = clean-kr.am clean.am compile-kr.am compile-vars.am \
compile.am data.am depend.am dist-subd-top.am dist-subd-vars.am \
dist-subd.am dist-vars.am dist.am footer.am header-vars.am header.am \
libscripts.am libprograms.am libraries-vars.am libraries.am library.am \
mans-vars.am mans.am packagedata.am program.am programs.am remake-hdr.am \

texinfos-vars.am texinfos.am hack-make.sed nl-remove.sed
File: automake.info, Node: Sources, Prev: Data, Up: Other objects
Built sources
=============
Occasionally a file which would otherwise be called "source" (eg a C
`.h' file) is actually derived from some other file. Such files should
be listed in the `BUILT_SOURCES' variable.
Files listed in `BUILT_SOURCES' are built before any automatic
dependency tracking is done. Built sources are included in a
distribution.

Building documentation
**********************
Currently Automake provides support for Texinfo and man pages.
* Menu:
* Texinfo:: Texinfo
* Man pages:: Man pages
File: automake.info, Node: Texinfo, Next: Man pages, Up: Documentation
Texinfo
=======
If the current directory contains Texinfo source, you must declare it
with the `TEXINFOS' primary. Generally Texinfo files are converted
into info, and thus the `info_TEXINFOS' macro is most commonly used
here. Note that any Texinfo source file must end in the `.texi'
extension (`.texinfo' won't work).
If the `.texi' file `@include's `version.texi', then that file will
be automatically generated. `version.texi' defines three Texinfo
macros you can reference: `EDITION', `VERSION', and `UPDATED'. The
first two hold the version number of your package (but are kept
separate for clarity); the last is the date the primary file was last
modified. The `version.texi' support requires the `mdate-sh' program;
this program is supplied with Automake.
Sometimes an info file actually depends on more than one `.texi'
file. For instance, in the `xdvik' distribution, `kpathsea.texi'
includes the files `install.texi', `copying.texi', and `freedom.texi'.
You can tell Automake about these dependencies using the
`texi_TEXINFOS' variable. Here is how `xdvik' could do it:
info_TEXINFOS = kpathsea.texi
kpathsea_TEXINFOS = install.texi copying.texi freedom.texi
Automake will warn if a directory containing Texinfo source does not
also contain the file `texinfo.tex'. This file is supplied with
Automake.
Automake generates an `install-info' target; some people apparently
use this.
File: automake.info, Node: Man pages, Prev: Texinfo, Up: Documentation
Man pages
=========
A package can also include man pages. (Though see the GNU standards
on this matter, *Note Man Pages: (standards.info)Man Pages.) Man pages
are declared using the `MANS' primary. Generally the `man_MANS' macro
is used. Man pages are automatically installed in the correct
subdirectory of `mandir', based on the file extension.
By default, man pages are installed by `make install'. However,
since the GNU project does not require man pages, many maintainers do
not expend effort to keep the man pages up to date. In these cases, the
`no-installman' option will prevent the man pages from being installed
by default. The user can still explicitly install them via `make
install-man'.
Here is how the documentation is handled in GNU `cpio' (which
includes both Texinfo documentation and man pages):
info_TEXINFOS = cpio.texi
man_MANS = cpio.1 mt.1
Texinfo source, info pages and man pages are all considered to be
source for the purposes of making a distribution.

What Gets Installed
*******************
Naturally, Automake handles the details of actually installing your
program once it has been built. All `PROGRAMS', `SCRIPTS',
`LIBRARIES', `DATA' and `HEADERS' are automatically installed in the
appropriate places.
Automake also handles installing any specified info and man pages.
Automake generates separate `install-data' and `install-exec'
targets, in case the installer is installing on multiple machines which
share directory structure - these targets allow the machine-independent
parts to be installed only once. The `install' target depends on both
of these targets.
Automake also generates an `uninstall' target, and an `installdirs'
target.
It is possible to extend this mechanism by defining an
`install-exec-local' or `install-data-local' target. If these targets
exist, they will be run at `make install' time.
File: automake.info, Node: Clean, Next: Dist, Prev: Install, Up: Top
What Gets Cleaned
*****************
The GNU Makefile Standards specify a number of different clean rules.
Generally the files that can cleaned are determined automatically by
Automake. Of course, Automake also recognizes some variables that can
be defined to specify additional files to clean. These variables are
`MOSTLYCLEANFILES', `CLEANFILES', `DISTCLEANFILES', and
`MAINTAINERCLEANFILES'.
In Automake, the `automake' program is not automatically removed,
because it is an executable script. So this code in `Makefile.am'
causes it to be removed by `make clean':
CLEANFILES = automake
File: automake.info, Node: Dist, Next: Tests, Prev: Clean, Up: Top
What Goes in a Distribution
***************************
The `dist' target in the generated `Makefile.in' can be used to
generate a gzip'd `tar' file for distribution. The tar file is named
based on the PACKAGE and VERSION variables.
For the most part, the files to distribute are automatically found by
Automake: all source files are automatically included in a distribution,
as are all `Makefile.am's and `Makefile.in's. Automake also has a
built-in list of commonly used files which, if present in the current
directory, are automatically included. This list is printed by
`automake --help'. Also, files which are read by `configure' (ie, the
source files corresponding to the files specified in the `AC_OUTPUT'
invocation) are automatically distributed.
Still, sometimes there are files which must be distributed, but which
are not covered in the automatic rules. These files should be listed in
the `EXTRA_DIST' variable.
Occasionally it is useful to be able to change the distribution
before it is packaged up. If the `dist-hook' target exists, it is run
after the distribution directory is filled, but before the actual tar
(or shar) file is created. One way to use this is for distributing file
in subdirectories for which a new `Makefile.am' is overkill:
dist-hook:
mkdir $(distdir)/random
cp -p random/a1 random/a2 $(distdir)/random
Automake also generates a `distcheck' target which can be help to
ensure that a given distribution will actually work. `distcheck' makes
a distribution, and then tries to do a `VPATH' build.
File: automake.info, Node: Tests, Next: Options, Prev: Dist, Up: Top
Support for test suites
***********************
Automake supports a two forms of test suite.
If the variable `TESTS' is defined, its value is taken to be a list
of programs to run in order to do the testing. The programs can either
be derived objects or source objects; the generated rule will look both
in SRCDIR and `.'. The number of failures will be printed at the end
of the run.
If `dejagnu' appears in `AUTOMAKE_OPTIONS', then the a
`dejagnu'-based test suite is assumed. The value of the variable
`DEJATOOL' is passed as the `--tool' argument to `runtest'; it defaults
to the name of the package. The variables `EXPECT', `RUNTEST' and
`RUNTESTFLAGS' can also be overridden to provide project-specific
values. For instance, you will need to do this if you are testing a
compiler toolchain, because the default values do not take into account
host and target names.
In either case, the testing is done via `make check'.
File: automake.info, Node: Options, Next: Miscellaneous, Prev: Tests, Up: Top
Changing Automake's Behavior
****************************
Various features of Automake can be controlled by options in the
`Makefile.am'. Such options are listed in a special variable named
`AUTOMAKE_OPTIONS'. Currently understood options are:
`gnits'
`gnu'
`foreign'
The same as the corresponding `--strictness' option.
`no-installman'
The generated `Makefile.in' will not cause man pages to be
installed by default. However, an `install-man' target will still
be available for optional installation.
`ansi2knr'
Turn on automatic de-ANSI-fication.
`dist-shar'
Generate a `dist-shar' target as well as the ordinary `dist'
target.
`dist-zip'
Generate a `dist-zip' target as well as the ordinary `dist' target.
`no-dependencies'
This is similar to using `--include-deps' on the command line, but
is useful for those situations where you don't have the necessary
bits to make automatic dependency tracking work *Note
Dependencies::. In this case the effect is to effectively disable
automatic dependency tracking.
VERSION
A version number (eg `0.30') can be specified. If Automake is not
newer than the version specified, creation of the `Makefile.in'
will be suppressed.
Unrecognized options are diagnosed by `automake'.

Miscellaneous Rules
*******************
There are a few rules and variables that didn't fit anywhere else.
* Menu:
* Tags:: Interfacing to etags and mkid
* Suffixes:: Handling new file extensions
* Built:: Built sources
File: automake.info, Node: Tags, Next: Suffixes, Up: Miscellaneous
Interfacing to `etags'
======================
`automake' will generate rules to generate `TAGS' files for use with
GNU Emacs under some circumstances.
If any C source code or headers are present, then a `tags' target
will be generated for the directory.
At the topmost directory of a multi-directory package, a `tags'
target file will be generated which, when run, will generate a `TAGS'
file that includes by reference all `TAGS' files from subdirectories.
Also, if the variable `ETAGS_ARGS' is defined, a `tags' target will
be generated. This variable is intended for use in directories which
contain taggable source that `etags' does not understand.
Here is how Automake generates tags for its source, and for nodes in
its Texinfo file:
ETAGS_ARGS = automake.in --lang=none \
--regex='/^@node[ \t]+\([^,]+\)/\1/' automake.texi
Automake will also generate an `ID' target which will run `mkid' on
the source. This is only supported on a directory-by-directory basis.
File: automake.info, Node: Suffixes, Next: Built, Prev: Tags, Up: Miscellaneous
Handling new file extensions
============================
It is sometimes useful to introduce a new implicit rule to handle a
file type that Automake does not know about. If this is done, you must
notify GNU Make of the new suffixes. This can be done by putting a list
of new suffixes in the `SUFFIXES' variable.

When Automake Isn't Enough
**************************
Sometimes `automake' isn't enough. Then you just lose.
Actually, `automake's implicit copying semantics means that many
problems can be worked around by simply adding some `make' targets and
rules to `Makefile.in'. `automake' will ignore these additions.
There are some caveats to doing this. Although you can overload a
target already used by `automake', it is often inadvisable,
particularly in the topmost directory of a non-flat package. However,
various useful targets have a `-local' version you can specify in your
`Makefile.in'. Automake will supplement the standard target with these
user-supplied targets.
The targets that support a local version are `all', `info', `dvi',
`check', `install-data', `install-exec', and `uninstall'.
For instance, here is how to install a file in `/etc':
install-data-local:
$(INSTALL_DATA) $(srcdir)/afile /etc/afile
Some targets also have a way to run another target, called a "hook",
after their work is done. The hook is named after the principal target,
with `-hook' appended. The targets allowing hooks are `install-data',
`install-exec', and `dist'.
For instance, here is how to create a hard link to an installed
program:
install-exec-hook:
$(LN) $(bindir)/program $(bindir)/proglink
File: automake.info, Node: Distributing, Next: Examples, Prev: Extending, Up: Top
Distributing `Makefile.in's
***************************
Automake places no restrictions on the distribution of the resulting
`Makefile.in's. We still encourage software authors to distribute
their work under terms like those of the GPL, but doing so is not
required to use Automake.
Some of the files that can be automatically installed via the
`--add-missing' switch do fall under the GPL; examine each file to see.
File: automake.info, Node: Examples, Next: Future, Prev: Distributing, Up: Top
Some example packages
*********************
Here are some examples of how Automake can be used.
* Menu:
* Hello:: The simplest GNU program
* Tricky:: A trickier example
* Automake:: Automake's own use
* Textutils:: A deep hierarchy
File: automake.info, Node: Hello, Next: Tricky, Up: Examples
The simplest GNU program
========================
`hello' is renowned for its classic simplicity and versatility.
What better place to begin a tour? The below shows what could be used
as the Hello distribution's `Makefile.am'.
bin_PROGRAMS = hello
hello_SOURCES = hello.c version.c getopt.c getopt1.c getopt.h
hello_LDADD = @ALLOCA@
info_TEXINFOS = hello.texi
hello_TEXINFOS = gpl.texi
EXTRA_DIST = testdata
check-local: hello
@echo expect no output from diff
./hello > test.out
diff -c $(srcdir)/testdata test.out
rm -f test.out
Of course, Automake also requires some minor changes to
`configure.in'. The new `configure.in' would read:
dnl Process this file with autoconf to produce a configure script.
AC_INIT(hello.c)
VERSION=1.3
AC_SUBST(VERSION)
PACKAGE=hello
AC_SUBST(PACKAGE)
AC_PROG_CC
AC_PROG_CPP
AC_PROG_INSTALL
AC_STDC_HEADERS
AC_HAVE_HEADERS(string.h fcntl.h sys/file.h)
AC_ALLOCA
AC_OUTPUT(Makefile)
If Hello were really going to use Automake, the `version.c' file
would probably be deleted, or changed so as to be automatically
generated.
File: automake.info, Node: Tricky, Next: Automake, Prev: Hello, Up: Examples
A tricker example
=================
Here is another, trickier example. It shows how to generate two
programs (`ctags' and `etags') from the same source file (`etags.c').
The difficult part is that each compilation of `etags.c' requires
different `cpp' flags.
bin_PROGRAMS = etags ctags
ctags_SOURCES =
ctags_LDADD = ctags.o
ctags_DEPENDENCIES = ctags.o
etags.o:
$(COMPILE) -DETAGS_REGEXPS etags.c
ctags.o:
$(COMPILE) -DCTAGS -o ctags.o etags.c
Note that `ctags_SOURCES' is defined to be empty - that way no
implicit value is substituted. The implicit value, however, is used to
generate `etags' from `etags.o'.
`ctags_LDADD' is used to get `ctags.o' into the link line, while
`ctags_DEPENDENCIES' exists to make sure that `ctags.o' gets built in
the first place.
This is a somewhat pathological example.
File: automake.info, Node: Automake, Next: Textutils, Prev: Tricky, Up: Examples
Automake uses itself
====================
Automake, of course, uses itself to generate its `Makefile.in'.
Since Automake is a shallow package, it has more than one
`Makefile.am'. Here is the top-level `Makefile.am':
## Process this file with automake to create Makefile.in
AUTOMAKE_OPTIONS = gnits
MAINT_CHARSET = latin1
PERL = @PERL@
SUBDIRS = tests
bin_SCRIPTS = automake
info_TEXINFOS = automake.texi
pkgdata_DATA = clean-kr.am clean.am compile-kr.am compile-vars.am \
compile.am data.am depend.am \
dist-vars.am footer.am header.am header-vars.am \
kr-vars.am libraries-vars.am \
libraries.am library.am mans-vars.am \
program.am programs.am remake-hdr.am \
remake-subd.am remake.am scripts.am subdirs.am tags.am tags-subd.am \
tags-clean.am \
texi-version.am texinfos-vars.am texinfos.am \
libraries-clean.am programs-clean.am data-clean.am \
COPYING INSTALL texinfo.tex \
ansi2knr.c ansi2knr.1 \
aclocal.m4
## These must all be executable when installed.
pkgdata_SCRIPTS = config.guess config.sub install-sh mdate-sh mkinstalldirs
CLEANFILES = automake
# The following requires a fixed version of the Emacs 19.30 etags.
ETAGS_ARGS = automake.in --lang=none \
--regex='/^@node[ \t]+\([^,]+\)/\1/' automake.texi
## `test -x' is not portable. So we use Perl instead. If Perl
## doesn't exist, then this test is meaningless anyway.
# Check to make sure some installed files are executable.
installcheck-local:
$(PERL) -e "exit ! -x '$(pkgdatadir)/config.guess';"
$(PERL) -e "exit ! -x '$(pkgdatadir)/config.sub';"
$(PERL) -e "exit ! -x '$(pkgdatadir)/install-sh';"
$(PERL) -e "exit ! -x '$(pkgdatadir)/mdate-sh';"
$(PERL) -e "exit ! -x '$(pkgdatadir)/mkinstalldirs';"
# Some simple checks:
# * syntax check with perl4 and perl5.
# * make sure the scripts don't use 'true'
# * expect no instances of '${...}'
# These are only really guaranteed to work on my machine.
maintainer-check: automake check
$(PERL) -c -w automake
@if grep '^[^#].*true' $(srcdir)/[a-z]*.am; then \
echo "can't use 'true' in GNU Makefile" 1>&2; \
exit 1; \
else :; fi
@if test `fgrep '$${' $(srcdir)/[a-z]*.am | wc -l` -ne 0; then \
echo "found too many uses of '\$${'" 1>&2; \
exit 1; \
fi
if $(SHELL) -c 'perl4.036 -v' >/dev/null 2>&1; then \
perl4.036 -c -w automake; \
else :; fi
# Tag before making distribution. Also, don't make a distribution if
# checks fail. Also, make sure the NEWS file is up-to-date.
cvs-dist: maintainer-check
@if sed 1q NEWS | grep -e "$(VERSION)" > /dev/null; then :; else \
echo "NEWS not updated; not releasing" 1>&2; \
exit 1; \
fi
cvs tag `echo "Release-$(VERSION)" | sed 's/\./-/g'`
$(MAKE) dist
As you can see, Automake defines many of its own rules, to make the
maintainer's job easier. For instance the `cvs-dist' rule
automatically tags the current version in the CVS repository, and then
makes a standard distribution.
Automake consists primarily of one program, `automake', and a number
of auxiliary scripts. Automake also installs a number of programs
which are possibly installed via the `--add-missing' option; these
scripts are listed in the `pkgdata_SCRIPTS' variable.
Automake also has a `tests' subdirectory, as indicated in the
`SUBDIRS' variable above. Here is `tests/Makefile.am':
## Process this file with automake to create Makefile.in
AUTOMAKE_OPTIONS = gnits
TESTS = mdate.test vtexi.test acoutput.test instexec.test checkall.test \
acoutnoq.test acouttbs.test libobj.test proginst.test acoutqnl.test \
confincl.test spelling.test prefix.test badprog.test depend.test
EXTRA_DIST = defs
This is where all the tests are really run. `defs' is an
initialization file used by each test script; it is explicitly mentioned
because `automake' has no way of automatically finding it.
File: automake.info, Node: Textutils, Prev: Automake, Up: Examples
A deep hierarchy
================
The GNU textutils are a collection of programs for manipulating text
files. They are distributed as a deep package. The textutils have only
recently been modified to use Automake; the examples come from a
prerelease.
Here is the top-level `Makefile.am':
SUBDIRS = lib src doc man
In the `lib' directory, a library is built which is used by each
textutil. Here is `lib/Makefile.am':
noinst_LIBRARIES = tu
EXTRA_DIST = rx.c regex.c
tu_SOURCES = error.h getline.h getopt.h linebuffer.h \
long-options.h md5.h regex.h rx.h xstrtod.h xstrtol.h xstrtoul.h \
error.c full-write.c getline.c getopt.c getopt1.c \
linebuffer.c long-options.c md5.c memchr.c safe-read.c \
xmalloc.c xstrtod.c xstrtol.c xstrtoul.c
tu_LIBADD = @REGEXOBJ@ @LIBOBJS@ @ALLOCA@
The `src' directory contains the source for all the textutils - 23
programs in all. The `Makefile.am' for this directory also includes
some simple checking code, and constructs a `version.c' file on the fly:
bin_PROGRAMS = cat cksum comm csplit cut expand fmt fold head join md5sum \
nl od paste pr sort split sum tac tail tr unexpand uniq wc
noinst_HEADERS = system.h version.h
DISTCLEANFILES = stamp-v version.c
INCLUDES = -I$(top_srcdir)/lib
LDADD = version.o ../lib/libtu.a
$(PROGRAMS): version.o ../lib/libtu.a
AUTOMAKE_OPTIONS = ansi2knr
version.c: stamp-v
stamp-v: Makefile
rm -f t-version.c
echo '#include <config.h>' > t-version.c
echo '#include "version.h"' >> t-version.c
echo 'const char *version_string = "'GNU @PACKAGE@ @VERSION@'";' \
>> t-version.c
if cmp -s version.c t-version.c; then \
rm t-version.c; \
else \
mv t-version.c version.c; \
fi
echo timestamp > $@
check: md5sum
./md5sum \
--string="" \
--string="a" \
--string="abc" \
--string="message digest" \
--string="abcdefghijklmnopqrstuvwxyz" \
--string="ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789" \
--string="12345678901234567890123456789012345678901234567890123456789012345678901234567890" \
| diff -c $(srcdir)/md5-test.rfc -
The `doc' directory builds the info documentation for the textutils:
info_TEXINFOS = textutils.texi
And, last, the `man' directory installs the man pages for all the
textutils:
man_MANS = cat.1 cksum.1 comm.1 csplit.1 cut.1 expand.1 fmt.1 fold.1 head.1 \
join.1 md5sum.1 nl.1 od.1 paste.1 pr.1 sort.1 split.1 sum.1 tac.1 tail.1 \
tr.1 unexpand.1 uniq.1 wc.1
You can now see how easy it is to handle even a largish project using
Automake.

Some ideas for the future
*************************
Here are some things that might happen in the future:
* HTML support.
* The output will be cleaned up. For instance, only variables which
are actually used will appear in the generated `Makefile.in'.
* There will be support for automatically recoding a distribution.
The intent is to allow a maintainer to use whatever character set
is most convenient locally, but for all distributions to be
Unicode or ISO 10646 with the UTF-8 encoding.
