+=head1 NAME
+
+ExtUtils::MakeMaker - create an extension Makefile
+
+=head1 SYNOPSIS
+
+C<use ExtUtils::MakeMaker;>
+
+C<WriteMakefile( ATTRIBUTE =E<gt> VALUE [, ...] );>
+
+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
+
+or say
+
+ perl Makefile.PL
+ make myperl MAP_TARGET=myperl
+ make inst_perl MAP_TARGET=myperl
+
+In any case you will be prompted with the correct invocation of the
+C<inst_perl> target that installs the new binary into INSTALLBIN.
+
+make inst_perl per default writes some documentation of what has been
+done into the file C<$(INSTALLARCHLIB)/perllocal.pod>. This
+can be bypassed by calling make pure_inst_perl.
+
+Warning: the inst_perl: target will most probably overwrite your
+existing perl binary. Use with care!
+
+Sometimes you might want to build a statically linked perl although
+your system supports dynamic loading. In this case you may explicitly
+set the linktype with the invocation of the Makefile.PL or make:
-$Version = 3.7; # Last edited 19th Dec 1994 by Tim Bunce
+ perl Makefile.PL LINKTYPE=static # recommended
-use Config;
-use Carp;
-use Cwd;
+or
-require Exporter;
-@ISA = qw(Exporter);
-@EXPORT = qw(&WriteMakefile &mkbootstrap $Verbose &writeMakefile);
-@EXPORT_OK = qw($Version %att %skip %Recognized_Att_Keys @MM_Sections %MM_Sections);
+ make LINKTYPE=static # works on most systems
-$Is_VMS = $Config{'osname'} eq 'VMS';
-require ExtUtils::MM_VMS if $Is_VMS;
+=head2 Determination of Perl Library and Installation Locations
-use strict qw(refs);
+MakeMaker needs to know, or to guess, where certain things are
+located. Especially INST_LIB and INST_ARCHLIB (where to put the files
+during the make(1) run), PERL_LIB and PERL_ARCHLIB (where to read
+existing modules from), and PERL_INC (header files and C<libperl*.*>).
+
+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:
+
+ PERL_INC = PERL_SRC
+ PERL_LIB = PERL_SRC/lib
+ PERL_ARCHLIB = PERL_SRC/lib
+ INST_LIB = PERL_LIB
+ INST_ARCHLIB = PERL_ARCHLIB
+
+If an extension is being built away from the perl source then MakeMaker
+will leave PERL_SRC undefined and default to using the installed copy
+of the perl library. The other variables default to the following:
+
+ PERL_INC = $archlibexp/CORE
+ PERL_LIB = $privlibexp
+ PERL_ARCHLIB = $archlibexp
+ INST_LIB = ./blib/lib
+ INST_ARCHLIB = ./blib/arch
+
+If perl has not yet been installed then PERL_SRC can be defined on the
+command line as shown in the previous section.
+
+
+=head2 Which architecture dependent directory?
+
+If you don't want to keep the defaults for the INSTALL* macros,
+MakeMaker helps you to minimize the typing needed: the usual
+relationship between INSTALLPRIVLIB and INSTALLARCHLIB is determined
+by Configure at perl compilation time. MakeMaker supports the user who
+sets INSTALLPRIVLIB. If INSTALLPRIVLIB is set, but INSTALLARCHLIB not,
+then MakeMaker defaults the latter to be the same subdirectory of
+INSTALLPRIVLIB as Configure decided for the counterparts in %Config ,
+otherwise it defaults to INSTALLPRIVLIB. The same relationship holds
+for INSTALLSITELIB and INSTALLSITEARCH.
+
+MakeMaker gives you much more freedom than needed to configure
+internal variables and get different results. It is worth to mention,
+that make(1) also lets you configure most of the variables that are
+used in the Makefile. But in the majority of situations this will not
+be necessary, and should only be done, if the author of a package
+recommends it (or you know what you're doing).
+
+=head2 Using Attributes and Parameters
-$Version = $Version;# avoid typo warning
-$Verbose = 0;
-$^W=1;
+The following attributes can be specified as arguments to WriteMakefile()
+or as NAME=VALUE pairs on the command line:
+=cut
-=head1 NAME
+# The following "=item C" is used by the attrib_help routine
+# likewise the "=back" below. So be careful when changing it!
-ExtUtils::MakeMaker - create an extension Makefile
+=over 2
-=head1 SYNOPSIS
+=item C
-use ExtUtils::MakeMaker;
-WriteMakefile( ATTRIBUTE => VALUE [, ...] );
+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.
-=head1 DESCRIPTION
+=item CCFLAGS
-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.
+String that will be included in the compiler call command line between
+the arguments INC and OPTIMIZE.
-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.
+=item CONFIG
-=head2 Default Makefile Behaviour
+Arrayref. E.g. [qw(archname manext)] defines ARCHNAME & MANEXT from
+config.sh. MakeMaker will add to CONFIG the following values anyway:
+ar
+cc
+cccdlflags
+ccdlflags
+dlext
+dlsrc
+ld
+lddlflags
+ldflags
+libc
+lib_ext
+obj_ext
+ranlib
+sitelibexp
+sitearchexp
+so
-This section (not yet written) will describe how a default Makefile will behave.
+=item CONFIGURE
-=head2 Determination of Perl Library and Installation Locations
+CODE reference. The subroutine should return a hash reference. The
+hash may contain further attributes, e.g. {LIBS =E<gt> ...}, that have to
+be determined by some evaluation method.
-MakeMaker needs to know, or to guess, where certain things are located.
-Especially INST_LIB, INST_ARCHLIB, PERL_LIB, PERL_ARCHLIB and PERL_SRC.
+=item DEFINE
-Because installperl does not currently install header files (etc) into
-the library the Perl source code must be available when building
-extensions. Currently MakeMaker will default PERL_LIB and PERL_ARCHLIB
-to PERL_SRC/lib. Later, once installperl does install header files
-(etc) into the library, PERL_*LIB will only default to PERL_SRC/lib if
-the extension is in PERL_SRC/ext/* (e.g., a standard extension).
-Otherwise PERL_*LIB and PERL_SRC will default to the public library
-locations.
+Something like C<"-DHAVE_UNISTD_H">
-INST_LIB and INST_ARCHLIB default to PERL_LIB and PERL_ARCHLIB.
+=item DIR
-=head2 Useful Default Makefile Macros
+Ref to array of subdirectories containing Makefile.PLs e.g. [ 'sdbm'
+] in ext/SDBM_File
-FULLEXT = Pathname for extension directory (eg DBD/Oracle).
+=item DISTNAME
-BASEEXT = Basename part of FULLEXT. May be just equal FULLEXT.
+Your name for distributing the package (by tar file). This defaults to
+NAME above.
-ROOTEXT = Directory part of FULLEXT with leading slash (eg /DBD)
+=item DL_FUNCS
-PERL_LIB
+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
-PERL_ARCHLIB
+ {"$(NAME)" => ["boot_$(NAME)" ] }
-INST_LIB
+e.g.
-INST_ARCHLIB
+ {"RPC" => [qw( boot_rpcb rpcb_gettime getnetconfigent )],
+ "NetconfigPtr" => [ 'DESTROY'] }
-INST_LIBDIR = $(INST_LIB)$(ROOTEXT) (and INST_ARCHLIBDIR)
+=item DL_VARS
-INST_AUTODIR = $(INST_LIB)/auto/$(FULLEXT) (and INST_ARCHAUTODIR)
+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 ) ])
-=head2 Customizing The Generated Makefile
+=item EXCLUDE_EXT
-If the Makefile generated does not fit your purpose you can change it
-using the mechanisms described below.
+Array of extension names to exclude when doing a static build. This
+is ignored if INCLUDE_EXT is present. Consult INCLUDE_EXT for more
+details. (e.g. [ qw( Socket POSIX ) ] )
-=head2 Using Attributes (and Parameters)
+This attribute may be most useful when specified as a string on the
+commandline: perl Makefile.PL EXCLUDE_EXT='Socket Safe'
-The following attributes can be specified as arguments to WriteMakefile()
-or as NAME=VALUE pairs on the command line:
+=item EXE_FILES
-(not yet complete)
+Ref to array of executable files. The files will be copied to the
+INST_SCRIPT directory. Make realclean will delete them from there
+again.
-=head2 Overriding MakeMaker Methods
+=item FIRST_MAKEFILE
-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:
+The name of the Makefile to be produced. Defaults to the contents of
+MAKEFILE, but can be overridden. This is used for the second Makefile
+that will be produced for the MAP_TARGET.
- sub MY::c_o { "new literal text" }
+=item FULLPERL
-or you can edit the default by saying something like:
+Perl binary able to run this extension.
- sub MY::c_o { $_=MM->c_o; s/old text/new text/; $_ }
+=item FUNCLIST
-If you still need a different solution, try to develop another
-subroutine, that fits your needs and submit the diffs to
-perl5-porters@isu.edu or comp.lang.perl as appropriate.
+This provides an alternate means to specify function names to be
+exported from the extension. Its value is a reference to an
+array of function names to be exported by the extension. These
+names are passed through unaltered to the linker options file.
+=item H
-=head1 AUTHORS
+Ref to array of *.h file names. Similar to C.

-=head1 MODIFICATION HISTORY
-
-v1, August 1994; by Andreas Koenig.
-
-Initial version. Based on Andy Dougherty's Makefile.SH work.
-
-v2, September 1994; by Tim Bunce.
-
-Use inheritance to implement overriding. Methods return text so
-derived methods can edit it before it's output. mkbootstrap() now
-executes the *_BS file in the DynaLoader package and automatically adds
-dl_findfile() if required. More support for nested modules.
-
-v3.0, October/November 1994; by Tim Bunce.
-
-Major reorganisation. Fixed perl binary locating code. Replaced single
-$(TOP) with $(PERL_SRC), $(PERL_LIB) and $(INST_LIB). Restructured
-code. Consolidated and/or eliminated several attributes and added
-argument name checking. Added initial pod documentation. Made generated
-Makefile easier to read. Added generic mechanism for passing parameters
-to specific sections of the Makefile. Merged in Andreas's perl version
-of Andy's extliblist.
-
-v3.1 November 11th 1994 by Tim Bunce
-
-Fixed AIX dynamic loading problem for nested modules. Fixed perl
-extliblist to give paths not names for libs so that cross-check works.
-Converted the .xs to .c translation to a suffix rule. Added a .xs.o
-rule for dumb makes. Added very useful PM, XS and DIR attributes. Used
-new attributes to make other sections smarter (especially clean and
-realclean). Make clean no longer deletes Makefile so that a later make
-realclean can still work. Fixed all known problems. Write temporary
-Makefile as Makefile.new and rename once complete.
-
-v3.2 November 18th 1994 By Tim Bunce
-
-Fixed typos, added makefile section (split out of a flattened
-perldepend section). Added subdirectories to test section. Added -lm
-fix for NeXT in extliblist. Added clean of *~ files. Tidied up clean
-and realclean sections to produce fewer lines. Major revision to the
-const_loadlibs comments for EXTRALIBS, LDLOADLIBS and BSLOADLIBS.
-Added LINKTYPE=\$(LINKTYPE) to subdirectory make invocations.
-Write temporary Makefile as MakeMaker.tmp. Write temporary xsubpp
-output files as xstmp.c instead of tmp. Now installs multiple PM files.
-Improved parsing of NAME=VALUE args. $(BOOTSTRAP) is now a dependency
-of $(INST_DYNAMIC). Improved init of PERL_LIB, INST_LIB and PERL_SRC.
-Reinstated $(TOP) for transition period. Removed CONFIG_SH attribute
-(no longer used). Put INST_PM back and include .pm and .pl files in
-current and lib directory. Allow OBJECT to contain newlines. ROOTEXT
-now has leading slash. Added INST_LIBDIR (containing ROOTEXT) and
-renamed AUTOEXT to INST_AUTO. Assorted other cosmetic changes.
-All known problems fixed.
-
-v3.3 November 27th 1994 By Andreas Koenig
-
-Bug fixes submitted by Michael Peppler and Wayne Scott. Changed the
-order how @libpath is constructed in C<new_extliblist()>. Improved
-pod-structure. Relative paths in C<-L> switches to LIBS are turned into
-absolute ones now. Included VMS support thanks to submissions by
-Charles Bailey. Added warnings for switches other than C<-L> or C<-l>
-in new_extliblist() and if a library is not found at all. Changed
-dependency distclean:clean to distclean:realclean. Added dependency
-all->config. ext.libs is now written without duplicates and empty
-lines. As old_extliblist() and new_extliblist() do not produce the
-same anymore, the default becomes new_extliblist(), though the warning
-remains, whenever they differ. The use of cflags is accompanied by a
-replacement: there will be a warning when the two routines lead to
-different results, but still the output of cflags will be used.
-Cosmetic changes (Capitalize globals, uncapitalize others, insert a
-C<:> as default for $postop). Added some verbosity.
-
-v3.4 December 7th 1994 By Andreas Koenig and Tim Bunce
-
-Introduced ARCH_LIB and required other perl files to be patched.
-
-v3.5 December 15th 1994 By Tim Bunce
-
-Based primarily on v3.3. Replaced ARCH_LIB with INST_ARCHLIB, which
-defaults to INST_LIB, because the rest of perl assumes that ./lib
-includes architecture dependent files. Ideally an ./archlib should
-exist, that would be more consistent and simplify installperl.
-Added linkext and $(INST_PM) dependencies to all: target. The linkext
-target (and subroutine) exists solely to depend on $(LINKTYPE). Any
-Makefile.PLs using LINKTYPE => '...' where '...' is not 'static' or
-'dynamic' should be changed to use 'linkext' => { LINKTYPE => '...' }.
-
-Automatic determination of PERL_* and INST_* has been revised. The
-INST_* macros have INST_ARCH* and INST_*DIR variants. The ARCH variants
-point to the architecture specific directory and the *DIR variants
-include the module specific subdirectory path. So INST_AUTO is now
-INST_AUTODIR and an INST_ARCHAUTODIR has also been defined.
-
-An AUTOSPLITFILE tool macro has been defined which will AutoSplit any
-named file into any named auto directory. This replaces AUTOSPLITLIB.
-MKPATH now accepts multiple paths. The paths INST_LIBDIR,
-INST_ARCHLIBDIR, INST_AUTODIR and INST_ARCHAUTODIR are made by the
-config: target. A new ext.libs mechanism has been added. installpm has
-been split and now calls installpm_x per file. A section attribute
-mechanism has been added and skip cross-checking has been moved into a
-skipcheck function. MakeMaker now uses Cwd and File::Basename modules.
-
-v3.6 December 15th 1994 By Tim Bunce
-
-Added C and H attributes and corresponding macros. These default to the
-list of *.c and *.h files in the directory. C also includes *.c file
-names corresponding to any *.xs files in the directory. ARMAYBE should
-now be specified as an attribute of the dynamic_lib section. The installpm
-section now accepts a SPLITLIB attribute. This defaults to '$(INST_LIB)'.
-Improved automatic setting of INST_ARCHLIB. Newlines in OBJECT now translate
-into <space><backslash><newline><tab> for better formatting. Improved
-descriptive comments for EXTRALIBS, LDLOADLIBS and BSLOADLIBS. Bootstrap
-files are now always installed - (after a small patch) the DynaLoader will
-only read a non-empty bootstrap file. Subdirectory dependencies have
-been improved. The .c files produced from .xs files now depend on
-XSUBPPDEPS (the typemaps).
-
-
-=head1 NOTES
-
-MakeMaker development work still to be done:
-
-Needs more complete documentation.
-
-Replace use of cflags with %Config (taking note of hints etc)
-
-Move xsubpp and typemap into lib/ExtUtils/...
-
-The ext.libs file mechanism will need to be revised to allow a
-make-a-perl [list-of-static-extensions] script to work.
-
-Eventually eliminate use of $(PERL_SRC). This must wait until
-MakeMaker is the standard and Larry makes the required changes
-elsewhere.
-
-Add method to take a list of files and wrap it in a Makefile
-compatible way (<space><backslash><newline><tab>).

- NAME: Perl module name for this extension (DBD::Oracle)
- This defaults to the directory name.
-
- 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 '$(BASEEXT).o',
- but can be a long string containing all object files,
- e.g. "tkpBind.o tkpButton.o tkpCanvas.o"
- MYEXTLIB: If the extension links to a library that it builds
- set this to the name of the library (see SDBM_File)
-
- LIBS: An anonymous array of alternative library specifications
- to be searched for (in order) until at least one library
- is found.
- 'LIBS' => [ "-lgdbm", "-ldbm -lfoo", "-L/path -ldbm.nfs" ]
- Mind, that any element of the array contains a complete
- set of arguments for the ld command. So do not specify
- 'LIBS' => ["-ltcl", "-ltk", "-lX11" ], #wrong
- See ODBM_File/Makefile.PL for an example, where an
- array is needed. If you specify a scalar as in
- 'LIBS' => "-ltcl -ltk -lX11"
- MakeMaker will turn it into an array with one element.
-
- LDTARGET: defaults to "$(OBJECT)" and is used in the ld command
- (some machines need additional switches for bigger projects)
-
- DIR: Ref to array of subdirectories containing Makefile.PLs
- e.g. [ 'sdbm' ] in ext/SDBM_File
-
- PM: Hashref of .pm files and *.pl files to be installed.
- e.g. { 'name_of_file.pm' => '$(INST_LIBDIR)/install_as.pm' }
- By default this will include *.pm and *.pl. If a lib directory
- exists and is not listed in DIR (above) then any *.pm and
- *.pl files it contains will also be included by default.
-
- XS: Hashref of .xs files. MakeMaker will default this.
- e.g. { 'name_of_file.xs' => 'name_of_file.c' }
- The .c files will automatically be included in the list
- of files deleted by a make clean.
-
- C: Ref to array of *.c file names. Initialised from a directory scan
- and the values portion of the XS attribute hash. This is not
- currently used by MakeMaker but may be handy in Makefile.PLs.
-
- H: Ref to array of *.h file names. Similar to C: above.
-
- LINKTYPE: =>'static' or 'dynamic' (default unless usedl=undef in config.sh)
- Should only be used to force static linking (also see linkext below).
-
- CONFIG: =>[qw(archname manext)] defines ARCHNAME & MANEXT from config.sh
- SKIP: =>[qw(name1 name2)] skip (do not write) sections of the Makefile
-
- PERL:
- FULLPERL:
-
-Additional lowercase attributes can be used to pass parameters to the
-methods which implement that part of the Makefile. These are not
-normally required:
-
- installpm: {SPLITLIB => '$(INST_LIB)' (default) or '$(INST_ARCHLIB)'}
- linkext: {LINKTYPE => 'static', 'dynamic' or ''}
- dynamic_lib {ARMAYBE => 'ar', OTHERLDFLAGS => '...'}
- clean: {FILES => "*.xyz foo"}
- realclean: {FILES => '$(INST_AUTODIR)/*.xyz'}

+=head2 Overriding MakeMaker Methods
+
+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:
+
+ sub MY::c_o { "new literal text" }
+
+or you can edit the default by saying something like:
+
+ sub MY::c_o {
+ package MY; # so that "SUPER" works right
+ my $inherited = shift->SUPER::c_o(@_);
+ $inherited =~ s/old text/new text/;
+ $inherited;
}
- warn "Warning (non-fatal): No library found for -l$thislib\n" unless $found_lib>0;
+
+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@perl.org> or F<comp.lang.perl.moderated> 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
+ ';
}

-# --- Write a DynaLoader bootstrap file if required
+=head2 Hintsfile support
-sub mkbootstrap {
+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.
-=head1 NAME
+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
-mkbootstrap
+ $self->{LIBS} = ['-ldbm -lucb -lc'];
-=head1 DESCRIPTION
+=head2 Distribution Support
-Make a bootstrap file for use by this system's DynaLoader.
-It typically gets called from an extension Makefile.
+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.
-There is no .bs file supplied with the extension. Instead a _BS file
-which has code for the special cases, like posix for berkeley db on the
-NeXT.
+=over 4
-This file will get parsed, and produce a maybe empty
-@DynaLoader::dl_resolve_using array for the current architecture.
-That will be extended by $BSLOADLIBS, which was computed by Andy's
-extliblist script. If this array still is empty, we do nothing, else
-we write a .bs file with an @DynaLoader::dl_resolve_using array, but
-without any C<if>s, because there is no longer a need to deal with
-special cases.
+=item make distcheck
-The _BS file can put some code into the generated .bs file by placing
-it in $bscode. This is a handy 'escape' mechanism that may prove
-useful in complex situations.
+reports which files are below the build directory but not in the
+MANIFEST file and vice versa. (See ExtUtils::Manifest::fullcheck() for
+details)
-If @DynaLoader::dl_resolve_using contains C<-L*> or C<-l*> entries then
-mkbootstrap will automatically add a dl_findfile() call to the
-generated .bs file.
+=item make skipcheck

+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
+
+ ExtUtils::MakeMaker::WriteEmptyMakefile();
+
+instead of WriteMakefile().
+
+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).
