that can be individually overridden. Each subroutine returns the text
it wishes to have written to the Makefile.
-=head2 Hintsfile support
+MakeMaker is object oriented. Each directory below the current
+directory that contains a Makefile.PL. Is treated as a separate
+object. This makes it possible to write an unlimited number of
+Makefiles with a single invocation of WriteMakefile().
-MakeMaker.pm uses the architecture specific information from
-Config.pm. In addition it evaluates architecture specific hints files
-in a C<hints/> directory. The hints files are expected to be named
-like their counterparts in C<PERL_SRC/hints>, but with an C<.pl> file
-name extension (eg. C<next_3_2.pl>). They are simply C<eval>ed by
-MakeMaker within the WriteMakefile() subroutine, and can be used to
-execute commands as well as to include special variables. The rules
-which hintsfile is chosen are the same as in Configure.
-
-The hintsfile is eval()ed immediately after the arguments given to
-WriteMakefile are stuffed into a hash reference $self but before this
-reference becomes blessed. So if you want to do the equivalent to
-override or create an attribute you would say something like
-

-=head2 What's new in version 5 of MakeMaker
+The short answer is: Don't.
-MakeMaker 5 is pure object oriented. This allows us to write an
-unlimited number of Makefiles with a single perl process. 'perl
-Makefile.PL' with MakeMaker 5 goes through all subdirectories
-immediately and evaluates any Makefile.PL found in the next level
-subdirectories. The benefit of this approach comes in useful for both
-single and multi directories extensions.
+ Always begin with h2xs.
+ Always begin with h2xs!
+ ALWAYS BEGIN WITH H2XS!
-Multi directory extensions have an immediately visible speed
-advantage, because there's no startup penalty for any single
-subdirectory Makefile.
-
-Single directory packages benefit from the much improved
-needs_linking() method. As the main Makefile knows everything about
-the subdirectories, a needs_linking() method can now query all
-subdirectories if there is any linking involved down in the tree. The
-speedup for PM-only Makefiles seems to be around 1 second on my
-Indy 100 MHz.
-
-=head2 Incompatibilities between MakeMaker 5.00 and 4.23
-
-There are no incompatibilities in the short term, as all changes are
-accompanied by short-term workarounds that guarantee full backwards
-compatibility.
-
-You are likely to face a few warnings that expose deprecations which
-will result in incompatibilities in the long run:
-
-You should not use %att directly anymore. Instead any subroutine you
-override in the MY package will be called by the object method, so you
-can access all object attributes directly via the object in $_[0].
-
-You should not call the class methos MM->something anymore. Instead
-you should call the superclass. Something like
-
- sub MY::constants {
- my $self = shift;
- $self->MM::constants();
- }
+even if you're not building around a header file, and even if you
+don't have an XS component.
-Especially the libscan() and exescan() methods should be altered
-towards OO programming, that means do not expect that $_ to contain
-the path but rather $_[1].
+Run h2xs(1) before you start thinking about writing a module. For so
+called pm-only modules that consist of C<*.pm> files only, h2xs has
+the C<-X> switch. This will generate dummy files of all kinds that are
+useful for the module developer.
-Try to build several extensions simultanously to debug your
-Makefile.PL. You can unpack a bunch of distributed packages within one
-directory and run
+The medium answer is:
- perl -MExtUtils::MakeMaker -e 'WriteMakefile()'
-
-That's actually fun to watch :)
-
-Do not use exit() in your Makefile.PL. MakeMaker tries hard to enable
-multi-module builds in one go.
-
-Final suggestion: Try to delete all of your MY:: subroutines and
-watch, if you really still need them. MakeMaker might already do what
-you want without them. If you see no way to avoid your own subroutine
-solution, please let us know about the problem.

+=head2 make testdb
+
+A useful variation of the above is the target C<testdb>. It runs the
+test under the Perl debugger (see L<perldebug>). If the file
+F<test.pl> exists in the current directory, it is used for the test.
+
+If you want to debug some other testfile, set C<TEST_FILE> variable
+thusly:
+
+ make testdb TEST_FILE=t/mytest.t
+
+By default the debugger is called using C<-d> option to perl. If you
+want to specify some other option, set C<TESTDB_SW> variable:
+
+ make testdb TESTDB_SW=-Dx
+
=head2 make install
make alone puts all relevant files into directories that are named by
-the macros INST_LIB, INST_ARCHLIB, INST_EXE, INST_MAN1DIR, and
-INST_MAN3DIR. All these default to something below ./blib if
-you are I<not> building below the perl source directory. If you I<are>
-building below the perl source, INST_LIB and INST_ARCHLIB default to
- ../../lib, and INST_EXE is not defined.
+the macros INST_LIB, INST_ARCHLIB, INST_SCRIPT, INST_HTMLLIBDIR,
+INST_HTMLSCRIPTDIR, INST_MAN1DIR, and INST_MAN3DIR. All these default
+to something below ./blib if you are I<not> building below the perl
+source directory. If you I<are> building below the perl source,
+INST_LIB and INST_ARCHLIB default to ../../lib, and INST_SCRIPT is not
+defined.
The I<install> target of the generated Makefile copies the files found
below each of the INST_* directories to their INSTALL*
counterparts. Which counterparts are chosen depends on the setting of
INSTALLDIRS according to the following table:
- INSTALLDIRS set to
- perl site
+ INSTALLDIRS set to
+ perl site
- INST_ARCHLIB INSTALLARCHLIB INSTALLSITEARCH
- INST_LIB INSTALLPRIVLIB INSTALLSITELIB
- INST_EXE INSTALLBIN
- INST_MAN1DIR INSTALLMAN1DIR
- INST_MAN3DIR INSTALLMAN3DIR
+ INST_ARCHLIB INSTALLARCHLIB INSTALLSITEARCH
+ INST_LIB INSTALLPRIVLIB INSTALLSITELIB
+ INST_HTMLLIBDIR INSTALLHTMLPRIVLIBDIR INSTALLHTMLSITELIBDIR
+ INST_HTMLSCRIPTDIR INSTALLHTMLSCRIPTDIR
+ INST_BIN INSTALLBIN
+ INST_SCRIPT INSTALLSCRIPT
+ INST_MAN1DIR INSTALLMAN1DIR
+ INST_MAN3DIR INSTALLMAN3DIR
The INSTALL... macros in turn default to their %Config
($Config{installprivlib}, $Config{installarchlib}, etc.) counterparts.
You can check the values of these variables on your system with
- perl -MConfig -le 'print join $/, map
- sprintf("%20s: %s", $_, $Config{$_}),
- grep /^install/, keys %Config'
+ perl '-V:install.*'
-If you don't want to keep the defaults, MakeMaker helps you to
-minimize the typing needed: the usual relationship between
-INSTALLPRIVLIB and INSTALLARCHLIB is determined by Configure at perl
-compilation time. MakeMaker supports the user who sets
-INSTALLPRIVLIB. If INSTALLPRIVLIB is set, but INSTALLARCHLIB not, then
-MakeMaker defaults the latter to be the same subdirectory of
-INSTALLPRIVLIB as Configure decided for the counterparts in %Config ,
-otherwise it defaults to INSTALLPRIVLIB. The same relationship holds
-for INSTALLSITELIB and INSTALLSITEARCH.
+And to check the sequence in which the library directories are
+searched by perl, run
-MakeMaker gives you much more freedom than needed to configure
-internal variables and get different results. It is worth to mention,
-that make(1) also lets you configure most of the variables that are
-used in the Makefile. But in the majority of situations this will not
-be necessary, and should only be done, if the author of a package
-recommends it (or you know what you're doing).

+=head2 PREFIX and LIB attribute

+go. The quickest way to install a module in a non-standard place might
+be

-
-BASEEXT = Basename part of FULLEXT. May be just equal FULLEXT.
-ROOTEXT = Directory part of FULLEXT with leading slash (eg /DBD)
+=head2 Which architecture dependent directory?
-INST_LIBDIR = C<$(INST_LIB)$(ROOTEXT)>
-
-INST_AUTODIR = C<$(INST_LIB)/auto/$(FULLEXT)>

-# The following "=item C" is used by the attrib_help routine
-# likewise the "=back" below. So be careful when changing it!

+=item ABSTRACT
+
+One line description of the module. Will be included in PPD file.

+=item ABSTRACT_FROM
+
+Name of the file that contains the package description. MakeMaker looks
+for a line in the POD matching /^($package\s-\s)(.*)/. This is typically
+the first line in the "=head1 NAME" section. $2 becomes the abstract.

+=item BINARY_LOCATION
+
+Used when creating PPD files for binary packages. It can be set to a
+full or relative path or URL to the binary archive for a particular
+architecture. For example:
+
+ perl Makefile.PL BINARY_LOCATION=x86/Agent.tar.gz
+
+builds a PPD package that references a binary of the C<Agent> package,
+located in the C<x86> directory relative to the PPD itself.

+=item INCLUDE_EXT
+
+Array of extension names to be included when doing a static build.
+MakeMaker will normally build with all of the installed extensions when

=head2 Overriding MakeMaker Methods
or you can edit the default by saying something like:
sub MY::c_o {
- my $self = shift;
- local *c_o;
- $_=$self->MM::c_o;
- s/old text/new text/;
- $_;
+ package MY; # so that "SUPER" works right
+ my $inherited = shift->SUPER::c_o(@_);
+ $inherited =~ s/old text/new text/;
+ $inherited;
}
-Both methods above are available for backwards compatibility with
-older Makefile.PLs.
+If you are running experiments with embedding perl as a library into
+other applications, you might find MakeMaker is not sufficient. You'd
+better have a look at ExtUtils::Embed which is a collection of utilities
+for embedding.
If you still need a different solution, try to develop another
-subroutine, that fits your needs and submit the diffs to
-F<perl5-porters@nicoh.com> or F<comp.lang.perl.misc> as appropriate.

+=head2 Hintsfile support
+
+MakeMaker.pm uses the architecture specific information from
+Config.pm. In addition it evaluates architecture specific hints files
+in a C<hints/> directory. The hints files are expected to be named
+like their counterparts in C<PERL_SRC/hints>, but with an C<.pl> file
+name extension (eg. C<next_3_2.pl>). They are simply C<eval>ed by
+MakeMaker within the WriteMakefile() subroutine, and can be used to
+execute commands as well as to include special variables. The rules
+which hintsfile is chosen are the same as in Configure.
+
+The hintsfile is eval()ed immediately after the arguments given to
+WriteMakefile are stuffed into a hash reference $self but before this
+reference becomes blessed. So if you want to do the equivalent to
+override or create an attribute you would say something like
+
+ $self->{LIBS} = ['-ldbm -lucb -lc'];
+
=head2 Distribution Support
For authors of extensions MakeMaker provides several Makefile
=item make distclean
does a realclean first and then the distcheck. Note that this is not
-needed to build a new distribution as long as you are sure, that the
+needed to build a new distribution as long as you are sure that the
MANIFEST file is ok.
=item make manifest
=item make tardist
First does a distdir. Then a command $(PREOP) which defaults to a null
-command. Next it runs C<tar> on that directory into a tarfile and
+command, followed by $(TOUNIX), which defaults to a null command under
+UNIX, and will convert files in distribution directory to UNIX format
+otherwise. Next it runs C<tar> on that directory into a tarfile and
deletes the directory. Finishes with a command $(POSTOP) which
defaults to a null command.
following parameters are recognized:
CI ('ci -u')
- COMPRESS ('compress')
+ COMPRESS ('gzip --best')
POSTOP ('@ :')
PREOP ('@ :')
+ TO_UNIX (depends on the system)
RCS_LABEL ('rcs -q -Nv$(VERSION_SYM):')
SHAR ('shar')
- SUFFIX ('Z')
+ SUFFIX ('.gz')
TAR ('tar')
TARFLAGS ('cvf')
ZIP ('zip')
An example:
- WriteMakefile( 'dist' => { COMPRESS=>"gzip", SUFFIX=>"gz" })
+ WriteMakefile( 'dist' => { COMPRESS=>"bzip2", SUFFIX=>".bz2" })

+OK, as opposed to I<work> OK (say, this system-dependent module builds
+in a subdirectory of some other distribution, or is listed as a
