-MakeMaker.pm uses the architecture specific information from
-Config.pm. In addition the extension may contribute to the C<%Config>
-hash table of Config.pm by supplying 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. If there is no
-hintsfile for the actual system, but for some previous releases of the
-same operating system, the latest one of those is used.
+__DATA__
-=head2 Default Makefile Behaviour
+package ExtUtils::MakeMaker;
-The automatically generated Makefile enables the user of the extension
-to invoke
+sub WriteMakefile {
+ Carp::croak "WriteMakefile: Need even number of args" if @_ % 2;
+ local $SIG{__WARN__} = \&warnhandler;
- perl Makefile.PL
- make
- make test # optionally set TEST_VERBOSE=1
- make install # See below
+ unless ($Setup_done++){
+ full_setup();
+ undef &ExtUtils::MakeMaker::full_setup; #safe memory
+ }
+ my %att = @_;
+ MM->new(\%att)->flush;
+}
-The Makefile to be produced may be altered by adding arguments of the
-form C<KEY=VALUE>. If the user wants to have the extension installed
-into a directory different from C<$Config{"installprivlib"}> it can be
-done by specifying
+sub prompt ($;$) {
+ my($mess,$def)=@_;
+ $ISA_TTY = -t STDIN && -t STDOUT ;
+ Carp::confess("prompt function called without an argument") unless defined $mess;
+ my $dispdef = defined $def ? "[$def] " : " ";
+ $def = defined $def ? $def : "";
+ my $ans;
+ if ($ISA_TTY) {
+ local $|=1;
+ print "$mess $dispdef";
+ chomp($ans = <STDIN>);
+ }
+ return $ans || $def;
+}
- perl Makefile.PL INST_LIB=~/myperllib INST_EXE=~/bin
+sub eval_in_subdirs {
+ my($self) = @_;
+ my($dir);
+ use Cwd 'cwd';
+ my $pwd = cwd();
-Note, that in this example MakeMaker does the tilde expansion for you
-and INST_ARCHLIB is set to either C<INST_LIB/$Config{"archname"}> if
-that directory exists and otherwise to INST_LIB.
+ foreach $dir (@{$self->{DIR}}){
+ my($abs) = $self->catdir($pwd,$dir);
+ $self->eval_in_x($abs);
+ }
+ chdir $pwd;
+}
-Other interesting targets in the generated Makefile are
+sub eval_in_x {
+ my($self,$dir) = @_;
+ package main;
+ chdir $dir or Carp::carp("Couldn't change to directory $dir: $!");
+# use FileHandle ();
+# my $fh = new FileHandle;

- make config # to check if the Makefile is up-to-date
- make clean # delete local temporary files (Makefile gets renamed)
- make realclean # delete all derived files (including installed files)
- make dist # produce a gzipped file ready for shipping
-
-The macros in the produced Makefile may be overridden on the command
-line to the make call as in the following example:
-
- make INST_LIB=/some/where INST_ARCHLIB=/some/where INST_EXE=/u/k/bin
-
-Note, that this is a solution provided by C<make> in general, so tilde
-expansion will probably not be available and INST_ARCHLIB will not be
-set automatically when INST_LIB is given as argument.
-
-The generated Makefile does not set any permissions. The installer has
-to decide, which umask should be in effect.
-
-=head2 Special case C<make install>
-
-The I<install> target of the generated Makefile is for system
-administrators only that have writing permissions on the
-system-specific directories $Config{installprivlib},
-$Config{installarchlib}, and $Config{installbin}. This works, because
-C<make> alone in fact puts all relevant files into directories that
-are named by the macros INST_LIB, INST_ARCHLIB, and INST_EXE. All
-three default to ./blib if you are not building below the perl source
-directory. C<make install> is just a recursive call to C<make> with
-the three relevant parameters set accordingly to the system-wide
-defaults.
-
-C<make install> per default writes some documentation of what has been
-done into the file C<$Config{'installarchlib'}/perllocal.pod>. This is
-an experimental feature. It can be bypassed by calling C<make
-pure_install>.
-
-Users that do not have privileges on the system but want to install
-the relevant files of the module into their private library or binary
-directories do not call C<make install>. In priciple they have the
-choice to either say
-
- # case: trust the module
- perl Makefile.PL INST_LIB=~/perllib INST_EXE=~/bin

- make test

-=head2 Support to Link a new Perl Binary
+ IMPORTS
-An extension that is built with the above steps is ready to use on
-systems supporting dynamic loading. On systems that do not support
-dynamic loading, any newly created extension has to be linked together
-with the available ressources. MakeMaker supports the linking process
-by creating appropriate targets in the Makefile whenever an extension
-is built. You can invoke the corresponding section of the makefile with
+ installpm
+ /;
- make perl
+ # IMPORTS is used under OS/2
-That produces a new perl binary in the current directory with all
-extensions linked in that can be found in INST_ARCHLIB and
-PERL_ARCHLIB.
+ # ^^^ installpm is deprecated, will go about Summer 96
-The binary can be installed into the directory where perl normally
-resides on your machine with
+ # @Overridable is close to @MM_Sections but not identical. The
+ # order is important. Many subroutines declare macros. These
+ # depend on each other. Let's try to collect the macros up front,
+ # then pasthru, then the rules.
- make inst_perl
+ # MM_Sections are the sections we have to call explicitly
+ # in Overridable we have subroutines that are used indirectly
-To produce a perl binary with a different name than C<perl>, either say
- perl Makefile.PL MAP_TARGET=myperl

- perl Makefile.PL
- make myperl MAP_TARGET=myperl
- make inst_perl MAP_TARGET=myperl

-C<inst_perl> target that installs the new binary into
-$Config{'installbin'}.

- NAME: Perl module name for this extension (DBD::Oracle)
- This will default to the directory name but should
- be explicitly defined in the Makefile.PL.
-
- DISTNAME: Your name for distributing the package (by tar file)
- This defaults to NAME above.
-
- VERSION: Your version number for distributing the package.
- This defaults to 0.1.
-
- INST_LIB: Perl library directory to install the module into.
- INST_ARCHLIB: Perl architecture-dependent library to install into
- (defaults to INST_LIB)
-
- PERL_LIB: Directory containing the Perl library to use.
- PERL_SRC: Directory containing the Perl source code
- (use of this should be avoided, it may be undefined)
-
- INC: Include file dirs eg: '-I/usr/5include -I/path/to/inc'
- DEFINE: something like "-DHAVE_UNISTD_H"
- OBJECT: List of object files, defaults to '$(BASEEXT).o',
- but can be a long string containing all object files,
- e.g. "tkpBind.o tkpButton.o tkpCanvas.o"
- MYEXTLIB: If the extension links to a library that it builds
- set this to the name of the library (see SDBM_File)
-
- LIBS: An anonymous array of alternative library specifications
- to be searched for (in order) until at least one library
- is found.
- 'LIBS' => [ "-lgdbm", "-ldbm -lfoo", "-L/path -ldbm.nfs" ]
- Mind, that any element of the array contains a complete
- set of arguments for the ld command. So do not specify
- 'LIBS' => ["-ltcl", "-ltk", "-lX11" ], #wrong
- See ODBM_File/Makefile.PL for an example, where an
- array is needed. If you specify a scalar as in
- 'LIBS' => "-ltcl -ltk -lX11"
- MakeMaker will turn it into an array with one element.
-
- LDFROM: defaults to "$(OBJECT)" and is used in the ld command
- to specify what files to link/load from
- (also see dynamic_lib below for how to specify ld flags)
-
- DIR: Ref to array of subdirectories containing Makefile.PLs
- e.g. [ 'sdbm' ] in ext/SDBM_File
-
- PMLIBDIRS: Ref to array of subdirectories containing library files.
- Defaults to [ 'lib', $(BASEEXT) ]. The directories will
- be scanned and any files they contain will
- be installed in the corresponding location in the library.
- A MY::libscan() function can be used to alter the behaviour.
- Defining PM in the Makefile.PL will override PMLIBDIRS.
-
- PM: Hashref of .pm files and *.pl files to be installed.
- e.g. { 'name_of_file.pm' => '$(INST_LIBDIR)/install_as.pm' }
- By default this will include *.pm and *.pl. If a lib directory
- exists and is not listed in DIR (above) then any *.pm and
- *.pl files it contains will also be included by default.
- Defining PM in the Makefile.PL will override PMLIBDIRS.
-
- XS: Hashref of .xs files. MakeMaker will default this.
- e.g. { 'name_of_file.xs' => 'name_of_file.c' }
- The .c files will automatically be included in the list
- of files deleted by a make clean.
-
- C: Ref to array of *.c file names. Initialised from a directory scan
- and the values portion of the XS attribute hash. This is not
- currently used by MakeMaker but may be handy in Makefile.PLs.
-
- H: Ref to array of *.h file names. Similar to C: above.
-
- PL_FILES: Ref to hash of files to be processed as perl programs. MakeMaker
- will default to any found C<*.PL> file (except C<Makefile.PL>) being
- keys and the basename of the file being the value. E.g.
- C<{ 'foobar.PL' => 'foobar' }>. The C<*.PL> files are expected to
- produce output to the target files themselves.
-
- EXE_FILES: Ref to array of executable files. The files will be copied to
- the INST_EXE directory. The installed files will be deleted
- by a make realclean.
-
- INST_EXE: Directory, where executable scripts should be installed. Defaults
- to "./blib", just to have a dummy location during testing.
- C<make install> will set INST_EXE to $Config{'installbin'}.
-
- LINKTYPE: =>'static' or 'dynamic' (default unless usedl=undef in config.sh)
- Should only be used to force static linking (also see linkext below).
-
- DL_FUNCS: Hashref of symbol names for routines to be made available as
- universal symbols. Each key/value pair consists of the package
- name and an array of routine names in that package. Used only
- under AIX (export lists) and VMS (linker options) at present.
- The routine names supplied will be expanded in the same way
- as XSUB names are expanded by the XS() macro.
- Defaults to { "$(NAME)" => [ "boot_$(NAME)" ] }.
- (e.g. { "RPC" => [qw( boot_rpcb rpcb_gettime getnetconfigent )],
- "NetconfigPtr" => [ 'DESTROY'] } )
-
- DL_VARS: Array of symbol names for variables to be made available as
- universal symbols. Used only under AIX (export lists) and VMS
- (linker options) at present. Defaults to [].
- (e.g. [ qw( Foo_version Foo_numstreams Foo_tree ) ])
-
- CONFIG: =>[qw(archname manext)] defines ARCHNAME & MANEXT from config.sh
- SKIP: =>[qw(name1 name2)] skip (do not write) sections of the Makefile
-
- MAP_TARGET: If it is intended, that a new perl binary be produced, this variable
- may hold a name for that binary. Defaults to C<perl>
-
- LIBPERL_A: The filename of the perllibrary that will be used together
- with this extension. Defaults to C<libperl.a>.
-
- PERL:
- FULLPERL:
-
-Additional lowercase attributes can be used to pass parameters to the
-methods which implement that part of the Makefile. These are not
-normally required:
-
- installpm: {SPLITLIB => '$(INST_LIB)' (default) or '$(INST_ARCHLIB)'}
- linkext: {LINKTYPE => 'static', 'dynamic' or ''}
- dynamic_lib: {ARMAYBE => 'ar', OTHERLDFLAGS => '...'}
- clean: {FILES => "*.xyz foo"}
- realclean: {FILES => '$(INST_ARCHAUTODIR)/*.xyz'}
- dist: {TARNAME=>'MyTarFile', TARFLAGS=>'cvfF', COMPRESS=>'gzip'}
- tool_autosplit: {MAXLEN => 8}

+=head1 NAME
+
+ExtUtils::MakeMaker - create an extension Makefile
+
+=head1 SYNOPSIS
+
+C<use ExtUtils::MakeMaker;>
+
+C<WriteMakefile( ATTRIBUTE =E<gt> VALUE [, ...] );>
- MY->init_dirscan();
- MY->init_others();
+which is really
+
+C<MM-E<gt>new(\%att)-E<gt>flush;>
+
+=head1 DESCRIPTION
+
+This utility is designed to write a Makefile for an extension module
+from a Makefile.PL. It is based on the Makefile.SH model provided by
+Andy Dougherty and the perl5-porters.
+
+It splits the task of generating the Makefile into several subroutines
+that can be individually overridden. Each subroutine returns the text
+it wishes to have written to the Makefile.
+
+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().
+
+=head2 How To Write A Makefile.PL
+
+The short answer is: Don't.
+
+ Always begin with h2xs.
+ Always begin with h2xs!
+ ALWAYS BEGIN WITH H2XS!
+
+even if you're not building around a header file, and even if you
+don't have an XS component.
+
+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.
+
+The medium answer is:
+
+ use ExtUtils::MakeMaker;
+ WriteMakefile( NAME => "Foo::Bar" );
+
+The long answer is the rest of the manpage :-)
+
+=head2 Default Makefile Behaviour
+
+The generated Makefile enables the user of the extension to invoke
+
+ perl Makefile.PL # optionally "perl Makefile.PL verbose"
+ make
+ make test # optionally set TEST_VERBOSE=1
+ make install # See below
+
+The Makefile to be produced may be altered by adding arguments of the
+form C<KEY=VALUE>. E.g.
+
+ perl Makefile.PL PREFIX=/tmp/myperl5
+
+Other interesting targets in the generated Makefile are
+
+ make config # to check if the Makefile is up-to-date
+ make clean # delete local temp files (Makefile gets renamed)
+ make realclean # delete derived files (including ./blib)
+ make ci # check in all the files in the MANIFEST file
+ make dist # see below the Distribution Support section
+
+=head2 make test
+
+MakeMaker checks for the existence of a file named F<test.pl> in the
+current directory and if it exists it adds commands to the test target
+of the generated Makefile that will execute the script with the proper
+set of perl C<-I> options.
+
+MakeMaker also checks for any files matching glob("t/*.t"). It will
+add commands to the test target of the generated Makefile that execute
+all matching files via the L<Test::Harness> module with the C<-I>
+switches set correctly.
+
+=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_SCRIPT, 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
+
+ INST_ARCHLIB INSTALLARCHLIB INSTALLSITEARCH
+ 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.
+
+You can check the values of these variables on your system with
+
+ perl '-V:install.*'
+
+And to check the sequence in which the library directories are
+searched by perl, run
+
+ perl -le 'print join $/, @INC'
+
+
+=head2 PREFIX and LIB attribute
+
+PREFIX and LIB can be used to set several INSTALL* attributes in one
+go. The quickest way to install a module in a non-standard place might
+be
+
+ perl Makefile.PL LIB=~/lib
+
+This will install the module's architecture-independent files into
+~/lib, the architecture-dependent files into ~/lib/$archname/auto.
+
+Another way to specify many INSTALL directories with a single
+parameter is PREFIX.
+
+ perl Makefile.PL PREFIX=~
+
+This will replace the string specified by $Config{prefix} in all
+$Config{install*} values.
+
+Note, that in both cases the tilde expansion is done by MakeMaker, not
+by perl by default, nor by make. Conflicts between parmeters LIB,
+PREFIX and the various INSTALL* arguments are resolved so that
+XXX
+
+If the user has superuser privileges, and is not working on AFS
+(Andrew File System) or relatives, then the defaults for
+INSTALLPRIVLIB, INSTALLARCHLIB, INSTALLSCRIPT, etc. will be appropriate,
+and this incantation will be the best:
+
+ perl Makefile.PL; make; make test
+ make install
+
+make install per default writes some documentation of what has been
+done into the file C<$(INSTALLARCHLIB)/perllocal.pod>. This feature
+can be bypassed by calling make pure_install.
+
+=head2 AFS users
+
+will have to specify the installation directories as these most
+probably have changed since perl itself has been installed. They will
+have to do this by calling
+
+ perl Makefile.PL INSTALLSITELIB=/afs/here/today \
+ INSTALLSCRIPT=/afs/there/now INSTALLMAN3DIR=/afs/for/manpages
+ make
+
+Be careful to repeat this procedure every time you recompile an
+extension, unless you are sure the AFS installation directories are
+still valid.
+
+=head2 Static Linking of a new Perl Binary
+
+An extension that is built with the above steps is ready to use on
+systems supporting dynamic loading. On systems that do not support
+dynamic loading, any newly created extension has to be linked together
+with the available resources. MakeMaker supports the linking process
+by creating appropriate targets in the Makefile whenever an extension
+is built. You can invoke the corresponding section of the makefile with
+
+ make perl
+
+That produces a new perl binary in the current directory with all
+extensions linked in that can be found in INST_ARCHLIB , SITELIBEXP,
+and PERL_ARCHLIB. To do that, MakeMaker writes a new Makefile, on
+UNIX, this is called Makefile.aperl (may be system dependent). If you
+want to force the creation of a new perl, it is recommended, that you
+delete this Makefile.aperl, so the directories are searched-through
+for linkable libraries again.
+
+The binary can be installed into the directory where perl normally
+resides on your machine with
+
+ make inst_perl
+
+To produce a perl binary with a different name than C<perl>, either say
+
+ perl Makefile.PL MAP_TARGET=myperl
+ make myperl
+ make inst_perl
- unlink("Makefile", "MakeMaker.tmp", $Is_VMS ? 'Descrip.MMS' : '');
- open MAKE, ">MakeMaker.tmp" or die "Unable to open MakeMaker.tmp: $!";
- select MAKE; $|=1; select STDOUT;
+or say
- print MAKE "# This Makefile is for the $att{NAME} extension to perl.\n#";
- print MAKE "# It was generated automatically by MakeMaker version $Version from the contents";
- print MAKE "# of Makefile.PL. Don't edit this file, edit Makefile.PL instead.";

+ perl Makefile.PL
+ make myperl MAP_TARGET=myperl
+ make inst_perl MAP_TARGET=myperl
- # build hash for SKIP to make testing easy
- %skip = map( ($_,1), @{$att{'SKIP'} || []});
+In any case you will be prompted with the correct invocation of the
+C<inst_perl> target that installs the new binary into INSTALLBIN.
- my $section;
- foreach $section ( @MM_Sections ){
- print "Processing Makefile '$section' section" if ($Verbose >= 2);

+Extensions may be built either using the contents of the perl source
+directory tree or from the installed perl library. The recommended way
+is to build extensions after you have run 'make install' on perl
+itself. You can do that in any directory on your hard disk that is not
+below the perl source tree. The support for extensions below the ext
+directory of the perl distribution is only good for the standard
+extensions that come with perl.
+If an extension is being built below the C<ext/> directory of the perl
+source then MakeMaker will set PERL_SRC automatically (e.g.,
+C<../..>). If PERL_SRC is defined and the extension is recognized as
+a standard extension, then other variables default to the following:
-sub neatvalue{
- my($v) = @_;
- return "undef" unless defined $v;

- return "'$v'" unless $t;
- return "[ ".join(', ',map("'$_'",@$v))." ]" if ($t eq 'ARRAY');

-}
+If you don't want to keep the defaults for the INSTALL* macros,
+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.
+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).

+Instead of specifying the VERSION in the Makefile.PL you can let
+MakeMaker parse a file to determine the version number. The parsing
+routine requires that the file named by VERSION_FROM contains one
+single line to compute the version number. The first line in the file
+that contains the regular expression
+ /([\$*])(([\w\:\']*)\bVERSION)\b.*\=/
-# --- Write a DynaLoader bootstrap file if required
+will be evaluated with eval() and the value of the named variable
+B<after> the eval() will be assigned to the VERSION attribute of the
+MakeMaker object. The following lines will be parsed o.k.:

+ *VERSION = \'1.01';

+=head2 Overriding MakeMaker Methods
-v4.04 Februeary 5th 1995 By Andreas Koenig
+If you cannot achieve the desired Makefile behaviour by specifying
+attributes you may define private subroutines in the Makefile.PL.
+Each subroutines returns the text it wishes to have written to
+the Makefile. To override a section of the Makefile you can
+either say:
-v4.05 February 8th 1995 By Andreas Koenig
+ sub MY::c_o { "new literal text" }
-v4.06 February 10th 1995 By Andreas Koenig
+or you can edit the default by saying something like:
-v4.061 February 12th 1995 By Andreas Koenig
+ sub MY::c_o {
+ package MY; # so that "SUPER" works right
+ my $inherited = shift->SUPER::c_o(@_);
+ $inherited =~ s/old text/new text/;
+ $inherited;
+ }
-v4.08 - 4.085 February 14th-21st 1995 by Andreas Koenig
+If you running experiments with embedding perl as a library into other
+applications, you might find MakeMaker not sufficient. You'd better
+have a look at ExtUtils::embed which is a collection of utilities for
+embedding.
-Introduces EXE_FILES and INST_EXE for installing executable scripts
-and fixes documentation to reflect the new variable.
+If you still need a different solution, try to develop another
+subroutine, that fits your needs and submit the diffs to
+F<perl5-porters@nicoh.com> or F<comp.lang.perl.misc> as appropriate.
-Introduces the automated documentation of the installation history. Every
- make install
-and
- make inst_perl
-add some documentation to the file C<$installarchlib/perllocal.pod>.
-This is done by the writedoc() routine in the MM_Unix class. The
-documentation is rudimentary until we find an agreement, what
-information is supposed to go into the pod.
+For a complete description of all MakeMaker methods see L<ExtUtils::MM_Unix>.
-Added ability to specify the another name than C<perl> for a new binary.
+Here is a simple example of how to add a new target to the generated
+Makefile:
-Both C<make perl> and C<makeaperl> now prompt the user, how to install
-the new binary after the build.
+ sub MY::postamble {
+ '
+ $(MYEXTLIB): sdbm/Makefile
+ cd sdbm && $(MAKE) all
+ ';
+ }
-Reduced noise during the make.
-Variable LIBPERL_A enables indirect setting of the switches -DEMBED,
--DDEBUGGING and -DMULTIPLICITY in the same way as done by cflags.
+=head2 Hintsfile support
-old_extliblist() code deleted, new_extliblist() renamed to extliblist().
+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.
-Improved algorithm in extliblist, that returns ('','','') if no
-library has been found, even if a C<-L> directory has been found.
+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
-Fixed a bug that didn't allow lib/ directory work as documented.
+ $self->{LIBS} = ['-ldbm -lucb -lc'];
-Allowed C<make test TEST_VERBOSE=1>
+=head2 Distribution Support
-v4.086 March 9 1995 by Andy Dougherty
+For authors of extensions MakeMaker provides several Makefile
+targets. Most of the support comes from the ExtUtils::Manifest module,
+where additional documentation can be found.
-Fixed some AIX buglets. Fixed DLD support for Linux with gcc 2.6.2.
+=over 4
-v4.09 March 31 1995 by Andreas Koenig
+=item make distcheck
-Patches from Tim (/usr/local/lib/perl5/hpux/CORE/libperl.a not found
-message eliminated, and a small makeaperl patch).
+reports which files are below the build directory but not in the
+MANIFEST file and vice versa. (See ExtUtils::Manifest::fullcheck() for
+details)
-blib now is a relative directory (./blib).
+=item make skipcheck
-Documentation bug fixed.
+reports which files are skipped due to the entries in the
+C<MANIFEST.SKIP> file (See ExtUtils::Manifest::skipcheck() for
+details)
-Chdir in the Makefile always followed by "&&", not by ";".
+=item make distclean
-The output of cflags is no longer directed to /dev/null, but the shell
-version of cflags is now only called once.
+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
+MANIFEST file is ok.
-The result of MakeMaker's cflags takes precedence over
-shell-cflags.
+=item make manifest
-Introduced a $(PASTHRU) variable, that doesn't have much effect yet,
-but now it's easier to add variables that have to be passed to
-recursive makes.
+rewrites the MANIFEST file, adding all remaining files found (See
+ExtUtils::Manifest::mkmanifest() for details)
-'make config' will now always reapply the original arguments to the
-'perl Makefile.PL'.
+=item make distdir
-MKPATH will be called only once for any directory (should speed up Tk
-building and installation considerably).
+Copies all the files that are in the MANIFEST file to a newly created
+directory with the name C<$(DISTNAME)-$(VERSION)>. If that directory
+exists, it will be removed first.
-"Subroutine mkbootstrap redefined" message eliminated. It was
-necessary to move &mkbootstrap and &mksymlists from @EXPORT to
-@EXPORT_OK.
+=item make disttest
-C<*.PL> files will be processed by C<$(PERL)>.
+Makes a distdir first, and runs a C<perl Makefile.PL>, a make, and
+a make test in that directory.
-Turned some globals into my() variables, where it was obvious to be an
-oversight.
+=item make tardist
-Changed some continuation lines so that they work on Solaris and Unicos.
+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.
-v4.091 April 3 1995 by Andy Dougherty
+=item make dist
-Another attempt to fix writedoc() from Dean Roehrich.
+Defaults to $(DIST_DEFAULT) which in turn defaults to tardist.
-v4.092 April 11 1995 by Andreas Koenig
+=item make uutardist
-Fixed a docu bug in hint file description. Added printing of a warning
-from eval in the hintfile section if the eval has errors. Moved
-check_hints() into the WriteMakefile() subroutine to avoid evaling
-hintsfiles for other uses of the module (mkbootstrap, mksymlists).
+Runs a tardist first and uuencodes the tarfile.
-Eliminated csh globbing to work around buggy Linux csh.
+=item make shdist
-In extliblist() libfoo.so.10 now wins against libfoo.so.9.
+First does a distdir. Then a command $(PREOP) which defaults to a null
+command. Next it runs C<shar> on that directory into a sharfile and
+deletes the intermediate directory again. Finishes with a command
+$(POSTOP) which defaults to a null command. Note: For shdist to work
+properly a C<shar> program that can handle directories is mandatory.
-Use $(CC) instead of $Config{'cc'} everywhere to allow overriding
-according to a patch by Dean Roehrich.
+=item make zipdist
-Introduce a ./extralibs.ld file that contains the contents of all
-relevant extralibs.ld files for a static build to shorten the command
-line for the linking of a new static perl.
+First does a distdir. Then a command $(PREOP) which defaults to a null
+command. Runs C<$(ZIP) $(ZIPFLAGS)> on that directory into a
+zipfile. Then deletes that directory. Finishes with a command
+$(POSTOP) which defaults to a null command.
-Minor cosmetics.
+=item make ci
-v4.093 April 12 1995 by Andy Dougherty
+Does a $(CI) and a $(RCS_LABEL) on all files in the MANIFEST file.
-Rename distclean target to plain dist. Insert a dummy distclean
-target that's the same as realclean. This is more consistent with the
-main perl makefile.
+=back
-Fix up extliblist() so even bizarre names like libfoo.so.10.0.1
-are handled.
+Customization of the dist targets can be done by specifying a hash
+reference to the dist attribute of the WriteMakefile call. The
+following parameters are recognized:
-Include Tim's suggestions about $verbose and more careful substitution
-of $(CC) for $Config{'cc'}.
+ CI ('ci -u')
+ COMPRESS ('compress')
+ POSTOP ('@ :')
+ PREOP ('@ :')
+ TO_UNIX (depends on the system)
+ RCS_LABEL ('rcs -q -Nv$(VERSION_SYM):')
+ SHAR ('shar')
+ SUFFIX ('Z')
+ TAR ('tar')
+ TARFLAGS ('cvf')
+ ZIP ('zip')
+ ZIPFLAGS ('-r')
-v4.094 April 12 1995 by Andy Dougherty
+An example:
-Include Andreas' improvement of $(CC) detection.
+ WriteMakefile( 'dist' => { COMPRESS=>"gzip", SUFFIX=>"gz" })
-v4.095 May 30 1995 by Andy Dougherty
+=head2 Disabling an extension
-Include installation of .pod and .pm files.
+If some events detected in F<Makefile.PL> imply that there is no way
+to create the Module, but this is a normal state of things, then you
+can create a F<Makefile> which does nothing, but succeeds on all the
+"usual" build targets. To do so, use
-Space out documentation for better printing with pod2man.
+ ExtUtils::MakeMaker::WriteEmptyMakefile();
-=head1 NOTES
+instead of WriteMakefile().
-MakeMaker development work still to be done:
+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).
-Needs more complete documentation.
