that can be individually overridden. Each subroutine returns the text
it wishes to have written to the Makefile.
-=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.
+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().
-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 How To Write A Makefile.PL
- $self->{LIBS} = ['-ldbm -lucb -lc'];
+The short answer is: Don't.
-=head2 What's new in version 5 of MakeMaker
+ Always begin with h2xs.
+ Always begin with h2xs!
+ ALWAYS BEGIN WITH H2XS!
-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.
+even if you're not building around a header file, and even if you
+don't have an XS component.
-Multi directory extensions have an immediately visible speed
-advantage, because there's no startup penalty for any single
-subdirectory Makefile.
+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.
-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.
+The medium answer is:
-=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();
- }
-
-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].
-
-Try to build several extensions simultanously to debug your
-Makefile.PL. You can unpack a bunch of distributed packages within one
-directory and run
-
- perl -MExtUtils::MakeMaker -e 'WriteMakefile()'
-
-That's actually fun to watch :)
-
-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. That's all about it.

+=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>

The I<install> target of the generated Makefile copies the files found
below each of the INST_* directories to their INSTALL*

INST_ARCHLIB INSTALLARCHLIB INSTALLSITEARCH
- INST_EXE INSTALLBIN
+ INST_LIB INSTALLPRIVLIB INSTALLSITELIB
+ 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.
-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.

+
+This will install the module's architecture-independent files into

+If you running experiments with embedding perl as a library into other
+applications, you might find MakeMaker 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.
+For a complete description of all MakeMaker methods see L<ExtUtils::MM_Unix>.
+
+Here is a simple example of how to add a new target to the generated
+Makefile:
+
+ sub MY::postamble {
+ '
+ $(MYEXTLIB): sdbm/Makefile
+ cd sdbm && $(MAKE) all
+ ';
+ }
+
+
+=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 tardist
-First does a command $(PREOP) which defaults to a null command. Does a
-distdir next and runs C<tar> on that directory into a tarfile. Then
-deletes the distdir. Finishes with a command $(POSTOP) which defaults
-to a null command.
+First does a distdir. Then a command $(PREOP) which defaults to a null
+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.
=item make dist
=item make shdist
-First does a command $(PREOP) which defaults to a null command. Does a
-distdir next and runs C<shar> on that directory into a sharfile. Then
-deletes the distdir. Finishes with a command $(POSTOP) which defaults
-to a null command. Note: For shdist to work properly a C<shar>
-program that can handle directories is mandatory.

-=head1 MODIFICATION HISTORY
+This may be useful if other modules expect this module to be I<built>
+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
+dependency in a CPAN::Bundle, but the functionality is supported by
+different means on the current architecture).
