    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:

    perl Makefile.PL LINKTYPE=static    # recommended

or

    make LINKTYPE=static                # works on most systems

=head2 Determination of Perl Library and Installation Locations

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

The following attributes may be specified as arguments to WriteMakefile()
or as NAME=VALUE pairs on the command line.

=over 2

=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 AUTHOR

String containing name (and email address) of package author(s). Is used
in PPD (Perl Package Description) files for PPM (Perl Package Manager).

=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 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.

=item CCFLAGS

String that will be included in the compiler call command line between
the arguments INC and OPTIMIZE.

=item CONFIG

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

=item CONFIGURE

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.

=item DEFINE

Something like C<"-DHAVE_UNISTD_H">

=item DESTDIR

This is the root directory into which the code will be installed.  It
I<prepends itself to the normal prefix>.  For example, if your code
would normally go into F</usr/local/lib/perl> you could set DESTDIR=~/tmp/
and installation would go into F<~/tmp/usr/local/lib/perl>.

This is primarily of use for people who repackage Perl modules.

NOTE: Due to the nature of make, it is important that you put the trailing
slash on your DESTDIR.  F<~/tmp/> not F<~/tmp>.

=item DIR

Ref to array of subdirectories containing Makefile.PLs e.g. [ 'sdbm'
] in ext/SDBM_File

=item DISTNAME

A safe filename for the package. 

Defaults to NAME above but with :: replaced with -.

For example, Foo::Bar becomes Foo-Bar.

=item DISTVNAME

Your name for distributing the package with the version number
included.  This is used by 'make dist' to name the resulting archive
file.

Defaults to DISTNAME-VERSION.

For example, version 1.04 of Foo::Bar becomes Foo-Bar-1.04.

On some OS's where . has special meaning VERSION_SYM may be used in
place of VERSION.

=item 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, OS/2,
VMS and Win32 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'] }

Please see the L<ExtUtils::Mksymlists> documentation for more information
about the DL_FUNCS, DL_VARS and FUNCLIST attributes.

=item DL_VARS

Array of symbol names for variables to be made available as universal symbols.
Used only under AIX, OS/2, VMS and Win32 at present.  Defaults to [].
(e.g. [ qw(Foo_version Foo_numstreams Foo_tree ) ])

=item EXCLUDE_EXT

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 ) ] )

This attribute may be most useful when specified as a string on the
command line:  perl Makefile.PL EXCLUDE_EXT='Socket Safe'

=item EXE_FILES

Ref to array of executable files. The files will be copied to the
INST_SCRIPT directory. Make realclean will delete them from there
again.

If your executables start with something like #!perl or
#!/usr/bin/perl MakeMaker will change this to the path of the perl
'Makefile.PL' was invoked with so the programs will be sure to run
properly even if perl is not in /usr/bin/perl.

=item FIRST_MAKEFILE

The name of the Makefile to be produced.  This is used for the second
Makefile that will be produced for the MAP_TARGET.

Defaults to 'Makefile' or 'Descrip.MMS' on VMS.

(Note: we couldn't use MAKEFILE because dmake uses this for something
else).

=item FULLPERL

Perl binary able to run this extension, load XS modules, etc...

=item FULLPERLRUN

Like PERLRUN, except it uses FULLPERL.

=item FULLPERLRUNINST

Like PERLRUNINST, except it uses FULLPERL.

=item FUNCLIST

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

Ref to array of *.h file names. Similar to C.

=item IMPORTS

This attribute is used to specify names to be imported into the
extension. Takes a hash ref.

It is only used on OS/2 and Win32.

=item INC

Include file dirs eg: C<"-I/usr/5include -I/path/to/inc">

=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
doing a static build, and that is usually the desired behavior.  If
INCLUDE_EXT is present then MakeMaker will build only with those extensions
which are explicitly mentioned. (e.g.  [ qw( Socket POSIX ) ])

It is not necessary to mention DynaLoader or the current extension when
filling in INCLUDE_EXT.  If the INCLUDE_EXT is mentioned but is empty then
only DynaLoader and the current extension will be included in the build.

This attribute may be most useful when specified as a string on the
command line:  perl Makefile.PL INCLUDE_EXT='POSIX Socket Devel::Peek'

=item INSTALLARCHLIB

Used by 'make install', which copies files from INST_ARCHLIB to this
directory if INSTALLDIRS is set to perl.

=item INSTALLBIN

Directory to install binary files (e.g. tkperl) into if
INSTALLDIRS=perl.

=item INSTALLDIRS

Determines which of the sets of installation directories to choose:
perl, site or vendor.  Defaults to site.

=item INSTALLMAN1DIR

=item INSTALLMAN3DIR

These directories get the man pages at 'make install' time if
INSTALLDIRS=perl.  Defaults to $Config{installman*dir}.

If set to 'none', no man pages will be installed.

=item INSTALLPRIVLIB

Used by 'make install', which copies files from INST_LIB to this
directory if INSTALLDIRS is set to perl.

Defaults to $Config{installprivlib}.

=item INSTALLSCRIPT

Used by 'make install' which copies files from INST_SCRIPT to this
directory if INSTALLDIRS=perl.

=item INSTALLSITEARCH

Used by 'make install', which copies files from INST_ARCHLIB to this
directory if INSTALLDIRS is set to site (default).

=item INSTALLSITEBIN

Used by 'make install', which copies files from INST_BIN to this
directory if INSTALLDIRS is set to site (default).

=item INSTALLSITELIB

Used by 'make install', which copies files from INST_LIB to this
directory if INSTALLDIRS is set to site (default).

=item INSTALLSITEMAN1DIR

=item INSTALLSITEMAN3DIR

INSTALLDIRS=site (default).  Defaults to 
$(SITEPREFIX)/man/man$(MAN*EXT).

If set to 'none', no man pages will be installed.

=item INSTALLSITESCRIPT

Used by 'make install' which copies files from INST_SCRIPT to this
directory if INSTALLDIRS is set to site (default).

=item INSTALLVENDORARCH

Used by 'make install', which copies files from INST_LIB to this
directory if INSTALLDIRS is set to vendor.

=item INSTALLVENDORMAN1DIR

=item INSTALLVENDORMAN3DIR

These directories get the man pages at 'make install' time if
INSTALLDIRS=vendor.  Defaults to $(VENDORPREFIX)/man/man$(MAN*EXT).
