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.
-
-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 What's new in version 5 of MakeMaker
-
-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.
+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().
-Multi directory extensions have an immediately visible speed
-advantage, because there's no startup penalty for any single
-subdirectory Makefile.
+=head2 How To Write A Makefile.PL
-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 short answer is: Don't.
-=head2 Incompatibilities between MakeMaker 5.00 and 4.23
+ Always begin with h2xs.
+ Always begin with h2xs!
+ ALWAYS BEGIN WITH H2XS!
-There are no incompatibilities in the short term, as all changes are
-accompanied by short-term workarounds that guarantee full backwards
-compatibility.
+even if you're not building around a header file, and even if you
+don't have an XS component.
-You are likely to face a few warnings that expose deprecations which
-will result in incompatibilities in the long run:
+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.
-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].
+The medium answer is:
-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 :)
-
-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.
+ use ExtUtils::MakeMaker;
+ WriteMakefile( NAME => "Foo::Bar" );
+The long answer is the rest of the manpage :-)
=head2 Default Makefile Behaviour
-The automatically generated Makefile enables the user of the extension
-to invoke
+The generated Makefile enables the user of the extension to invoke
perl Makefile.PL # optionally "perl Makefile.PL verbose"
make
=head2 make test
-MakeMaker checks for the existence of a file named "test.pl" in the

+=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'];

deletes the directory. Finishes with a command $(POSTOP) which
defaults to a null command.
