The extension you are trying to build apparently is rather old and
|
|
most probably outdated. We detect that from the fact, that a
|
|
subroutine "writeMakefile" is called, and this subroutine is not
|
|
supported anymore since about October 1994.
|
|
|
|
Please contact the author or look into CPAN (details about CPAN can be
|
|
found in the FAQ and at http:/www.perl.com) for a more recent version
|
|
of the extension. If you're really desperate, you can try to change
|
|
the subroutine name from writeMakefile to WriteMakefile and rerun
|
|
'perl Makefile.PL', but you're most probably left alone, when you do
|
|
so.

ExtUtils::MakeMaker - create an extension Makefile

|
|
=head1 SYNOPSIS
|
|
|
|
C<use ExtUtils::MakeMaker;>
|
|
|
|
C<WriteMakefile( ATTRIBUTE =E<gt> VALUE [, ...] );>
|
|
|

|
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 parameters LIB,
|
|
PREFIX and the various INSTALL* arguments are resolved so that

|
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:
|
|
|
|
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 = $archlibexp
|
|
INST_LIB = ./blib/lib
|
|
INST_ARCHLIB = ./blib/arch
|
|
|
|
If perl has not yet been installed then PERL_SRC can be defined on the
|
|
command line as shown in the previous section.
|
|
|
|
|
|
=head2 Which architecture dependent directory?
|
|
|
|
If you don't want to keep the defaults for the INSTALL* macros,
|
|
MakeMaker helps you to minimize the typing needed: the usual
|
|
relationship between INSTALLPRIVLIB and INSTALLARCHLIB is determined
|
|
by Configure at perl compilation time. MakeMaker supports the user who
|
|
sets INSTALLPRIVLIB. If INSTALLPRIVLIB is set, but INSTALLARCHLIB not,
|
|
then MakeMaker defaults the latter to be the same subdirectory of
|
|
INSTALLPRIVLIB as Configure decided for the counterparts in %Config ,
|
|
otherwise it defaults to INSTALLPRIVLIB. The same relationship holds
|
|
for INSTALLSITELIB and INSTALLSITEARCH.
|
|
|
|
MakeMaker gives you much more freedom than needed to configure
|
|
internal variables and get different results. It is worth to mention,
|
|
that make(1) also lets you configure most of the variables that are
|
|
used in the Makefile. But in the majority of situations this will not
|
|
be necessary, and should only be done, if the author of a package
|
|
recommends it (or you know what you're doing).
|
|
|
|
=head2 Using Attributes and Parameters
|
|
|
|
The following attributes can be specified as arguments to WriteMakefile()
|
|
or as NAME=VALUE pairs on the command line:
|
|
|
|
=over 2
|
|
|
|
=item AUTHOR
|
|
|
|
String containing name (and email address) of package author(s). Is used
|
|
in PPD (Perl Package Description) files for PPM (Perl Package Manager).
|
|
|
|
=item ABSTRACT
|
|
|
|
One line description of the module. Will be included in PPD file.
|
|
|
|
=item ABSTRACT_FROM
|
|
|
|
Name of the file that contains the package description. MakeMaker looks
|
|
for a line in the POD matching /^($package\s-\s)(.*)/. This is typically
|
|
the first line in the "=head1 NAME" section. $2 becomes the abstract.
|
|
|
|
=item 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 CAPI
|
|
|
|
Switch to force usage of the Perl C API even when compiling for PERL_OBJECT.
|
|
|
|
Note that this attribute is passed through to any recursive build,
|
|
but if and only if the submodule's Makefile.PL itself makes no mention
|
|
of the 'CAPI' attribute.
|
|
|
|
=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 DIR
|
|
|
|
Ref to array of subdirectories containing Makefile.PLs e.g. [ 'sdbm'
|
|
] in ext/SDBM_File
|
|
|
|
=item DISTNAME
|
|
|
|
Your name for distributing the package (by tar file). This defaults to
|
|
NAME above.
|
|
|
|
=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.
|
|
|
|
=item FIRST_MAKEFILE
|
|
|
|
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.
|
|
|
|
=item FULLPERL
|
|
|
|
Perl binary able to run this extension.
|
|
|
|
=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. 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.
|
|
|
|
=item INSTALLDIRS
|
|
|
|
Determines which of the two sets of installation directories to
|
|
choose: installprivlib and installarchlib versus installsitelib and
|
|
installsitearch. The first pair is chosen with INSTALLDIRS=perl, the
|
|
second with INSTALLDIRS=site. Default is site.
|
|
|
|
=item INSTALLMAN1DIR
|
|
|
|
This directory gets the man pages at 'make install' time. Defaults to
|
|
$Config{installman1dir}.
|
|
|
|
=item INSTALLMAN3DIR
|
|
|
|
This directory gets the man pages at 'make install' time. Defaults to
|
|
$Config{installman3dir}.
|
|
|
|
=item INSTALLPRIVLIB
|
|
|
|
Used by 'make install', which copies files from INST_LIB to this
|
|
directory if INSTALLDIRS is set to perl.
|
|
|
|
=item INSTALLSCRIPT
|
|
|
|
Used by 'make install' which copies files from INST_SCRIPT to this
|
|
directory.
|
|
|
|
=item INSTALLSITEARCH
|
|
|
|
Used by 'make install', which copies files from INST_ARCHLIB to this
|
|
directory if INSTALLDIRS is set to site (default).
|
|
|
|
=item INSTALLSITELIB
|
|
|
|
Used by 'make install', which copies files from INST_LIB to this
|
|
directory if INSTALLDIRS is set to site (default).
|
|
|
|
=item INST_ARCHLIB
|
|
|
|
Same as INST_LIB for architecture dependent files.
|
|
|
|
=item INST_BIN
|
|
|
|
Directory to put real binary files during 'make'. These will be copied
|
|
to INSTALLBIN during 'make install'
|
|
|
|
=item INST_EXE
|
|
|
|
Old name for INST_SCRIPT. Deprecated. Please use INST_SCRIPT if you
|
|
need to use it.
|
|
|
|
=item INST_LIB
|
|
|
|
Directory where we put library files of this extension while building
|
|
it.
|
|
|
|
=item INST_MAN1DIR
|
|
|
|
Directory to hold the man pages at 'make' time
|
|
|
|
=item INST_MAN3DIR
|
|
|
|
Directory to hold the man pages at 'make' time
|
|
|
|
=item INST_SCRIPT
|
|
|
|
Directory, where executable files should be installed during
|
|
'make'. Defaults to "./blib/bin", just to have a dummy location during
|
|
testing. make install will copy the files in INST_SCRIPT to
|
|
INSTALLSCRIPT.
|
|
|
|
=item LDFROM
|
|
|
|
defaults to "$(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)
|
|
|
|
=item LIB
|
|
|
|
LIB can only be set at C<perl Makefile.PL> time. It has the effect of
|
|
setting both INSTALLPRIVLIB and INSTALLSITELIB to that value regardless any
|
|
|
|
=item LIBPERL_A
|
|
|
|
The filename of the perllibrary that will be used together with this
|
|
extension. Defaults to libperl.a.
|
|
|
|
=item LIBS
|
|
|
|
An anonymous array of alternative library
|
|
specifications to be searched for (in order) until
|
|
at least one library is found. E.g.
|
|
|
|
'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"]
|
|
|
|
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.
|
|
|
|
=item LINKTYPE
|
|
|
|
'static' or 'dynamic' (default unless usedl=undef in
|
|
config.sh). Should only be used to force static linking (also see
|
|
linkext below).
|
|
|
|
=item MAKEAPERL
|
|
|
|
Boolean which tells MakeMaker, that it should include the rules to
|
|
make a perl. This is handled automatically as a switch by
|
|
MakeMaker. The user normally does not need it.
|
|
|
|
=item MAKEFILE
|
|
|
|
The name of the Makefile to be produced.
|
|
|
|
=item MAN1PODS
|
|
|
|
Hashref of pod-containing files. MakeMaker will default this to all
|
|
EXE_FILES files that include POD directives. The files listed
|
|
here will be converted to man pages and installed as was requested
|
|
at Configure time.
|
|
|
|
=item MAN3PODS
|
|
|
|
Hashref of .pm and .pod files. MakeMaker will default this to all
|
|
.pod and any .pm files that include POD directives. The files listed
|
|
here will be converted to man pages and installed as was requested
|
|
at Configure time.
|
|
|
|
=item MAP_TARGET
|
|
|
|
If it is intended, that a new perl binary be produced, this variable
|
|
may hold a name for that binary. Defaults to perl
|
|
|
|
=item MYEXTLIB
|
|
|
|
If the extension links to a library that it builds set this to the
|
|
name of the library (see SDBM_File)
|
|
|
|
=item 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.
|
|
|
|
=item NEEDS_LINKING
|
|
|
|
MakeMaker will figure out, if an extension contains linkable code
|
|
anywhere down the directory tree, and will set this variable
|
|
accordingly, but you can speed it up a very little bit, if you define
|
|
this boolean variable yourself.
|
|
|
|
=item NOECHO
|
|
|
|
Defaults to C<@>. By setting it to an empty string you can generate a
|
|
Makefile that echos all commands. Mainly used in debugging MakeMaker
|
|
itself.
|
|
|
|
=item NORECURS
|
|
|
|
Boolean. Attribute to inhibit descending into subdirectories.
|
|
|
|
=item NO_VC
|
|
|
|
In general any generated Makefile checks for the current version of
|
|
MakeMaker and the version the Makefile was built under. If NO_VC is
|
|
set, the version check is neglected. Do not write this into your
|
|
Makefile.PL, use it interactively instead.
|
|
|
|
=item OBJECT
|
|
|
|
List of object files, defaults to '$(BASEEXT)$(OBJ_EXT)', but can be a long
|
|
string containing all object files, e.g. "tkpBind.o
|
|
tkpButton.o tkpCanvas.o"
|
|
|
|
=item OPTIMIZE
|
|
|
|
Defaults to C<-O>. Set it to C<-g> to turn debugging on. The flag is
|
|
passed to subdirectory makes.
|
|
|
|
=item PERL
|
|
|
|
Perl binary for tasks that can be done by miniperl
|
|
|
|
=item PERLMAINCC
|
|
|
|
The call to the program that is able to compile perlmain.c. Defaults
|
|
to $(CC).
|
|
|
|
=item PERL_ARCHLIB
|
|
|
|
Same as above for architecture dependent files
|
|
|
|
=item PERL_LIB
|
|
|
|
Directory containing the Perl library to use.
|
|
|
|
=item PERL_SRC
|
|
|
|
Directory containing the Perl source code (use of this should be
|
|
avoided, it may be undefined)
|
|
|
|
=item PERM_RW
|
|
|
|
Desired permission for read/writable files. Defaults to C<644>.
|
|
See also L<MM_Unix/perm_rw>.
|
|
|
|
=item PERM_RWX
|
|
|
|
Desired permission for executable files. Defaults to C<755>.
|
|
See also L<MM_Unix/perm_rwx>.
|
|
|
|
=item PL_FILES
|
|
|
|
Ref to hash of files to be processed as perl programs. MakeMaker
|
|
will default to any found *.PL file (except Makefile.PL) being keys
|
|
and the basename of the file being the value. E.g.
|
|
|
|
{'foobar.PL' => 'foobar'}
|
|
|
|
The *.PL files are expected to produce output to the target files
|
|
themselves. If multiple files can be generated from the same *.PL
|
|
file then the value in the hash can be a reference to an array of

target file names. E.g.
|
|
|
|
{'foobar.PL' => ['foobar1','foobar2']}
|
|
|
|
=item 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 and the files found in
|
|
the PMLIBDIRS directories. Defining PM in the
|
|
Makefile.PL will override PMLIBDIRS.
|
|
|
|
=item PMLIBDIRS
|
|
|
|
Ref to array of subdirectories containing library files. Defaults to
|
|
[ 'lib', $(BASEEXT) ]. The directories will be scanned and I<any> files
|
|
they contain will be installed in the corresponding location in the
|
|
library. A libscan() method can be used to alter the behaviour.
|
|
Defining PM in the Makefile.PL will override PMLIBDIRS.
|
|
|
|
=item PPM_INSTALL_EXEC
|
|
|
|
Name of the executable used to run C<PPM_INSTALL_SCRIPT> below. (e.g. perl)
|
|
|
|
=item PPM_INSTALL_SCRIPT
|
|
|
|
Name of the script that gets executed by the Perl Package Manager after
|
|
the installation of a package.
|
|
|
|
=item PREFIX
|
|
|
|
Can be used to set the three INSTALL* attributes in one go (except for
|
|
probably INSTALLMAN1DIR, if it is not below PREFIX according to
|
|
%Config). They will have PREFIX as a common directory node and will
|
|
branch from that node into lib/, lib/ARCHNAME or whatever Configure
|
|
decided at the build time of your perl (unless you override one of
|
|
them, of course).
|
|
|
|
=item PREREQ_PM
|
|
|
|
Hashref: Names of modules that need to be available to run this
|
|
extension (e.g. Fcntl for SDBM_File) are the keys of the hash and the
|
|
desired version is the value. If the required version number is 0, we
|
|
only check if any version is installed already.
|
|
|
|
=item SKIP
|
|
|
|
Arryref. E.g. [qw(name1 name2)] skip (do not write) sections of the
|
|
Makefile. Caution! Do not use the SKIP attribute for the neglectible
|
|
speedup. It may seriously damage the resulting Makefile. Only use it,
|
|
if you really need it.
|
|
|
|
=item TYPEMAPS
|
|
|
|
Ref to array of typemap file names. Use this when the typemaps are
|
|
in some directory other than the current directory or when they are
|
|
not named B<typemap>. The last typemap in the list takes
|
|
precedence. A typemap in the current directory has highest
|
|
precedence, even if it isn't listed in TYPEMAPS. The default system
|
|
typemap has lowest precedence.
|
|
|
|
=item VERSION
|
|
|
|
Your version number for distributing the package. This defaults to
|
|
0.1.
|
|
|
|
=item VERSION_FROM
|
|
|
|
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.*\=/
|
|
|
|
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 = '1.00';
|
|
*VERSION = \'1.01';
|
|
( $VERSION ) = '$Revision: 1.222 $ ' =~ /\$Revision:\s+([^\s]+)/;
|
|
$FOO::VERSION = '1.10';
|
|
*FOO::VERSION = \'1.11';
|
|
|
|
but these will fail:
|
|
|
|
my $VERSION = '1.01';
|
|
local $VERSION = '1.02';
|
|
local $FOO::VERSION = '1.30';
|
|
|
|
The file named in VERSION_FROM is not added as a dependency to
|
|
Makefile. This is not really correct, but it would be a major pain
|
|
during development to have to rewrite the Makefile for any smallish
|
|
change in that file. If you want to make sure that the Makefile
|
|
contains the correct VERSION macro after any change of the file, you
|
|
would have to do something like
|
|
|
|
depend => { Makefile => '$(VERSION_FROM)' }
|
|
|
|
See attribute C<depend> below.
|
|
|
|
=item 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.
|
|
|
|
=item XSOPT
|
|
|
|
String of options to pass to xsubpp. This might include C<-C++> or
|
|
C<-extern>. Do not include typemaps here; the TYPEMAP parameter exists for
|
|
that purpose.
|
|
|
|
=item XSPROTOARG
|
|
|
|
May be set to an empty string, which is identical to C<-prototypes>, or
|
|
C<-noprototypes>. See the xsubpp documentation for details. MakeMaker
|
|
defaults to the empty string.
|
|
|
|
=item XS_VERSION
|
|
|
|
Your version number for the .xs file of this package. This defaults
|
|
to the value of the VERSION attribute.
|
|
|

ZIPFLAGS => '-rl', DIST_DEFAULT => 'private tardist' }
|
|
|
|
If you specify COMPRESS, then SUFFIX should also be altered, as it is
|
|
needed to tell make the target file of the compression. Setting
|
|
DIST_CP to ln can be useful, if you need to preserve the timestamps on
|
|
your files. DIST_CP can take the values 'cp', which copies the file,
|
|
'ln', which links the file, and 'best' which copies symbolic links and
|
|
links the rest. Default is 'best'.

with Pre-5.0 MakeMakers. Since version 5.00 of MakeMaker such a line

=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;
|
|
}
|
|
|
|
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<[email protected]> 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
|
|
';
|
|
}
|
|
|
|
|
|
=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
|
|
|
|
$self->{LIBS} = ['-ldbm -lucb -lc'];
|
|
|
|
=head2 Distribution Support
|
|
|
|
For authors of extensions MakeMaker provides several Makefile
|
|
targets. Most of the support comes from the ExtUtils::Manifest module,
|
|
where additional documentation can be found.
|
|
|
|
=over 4
|
|
|
|
=item make distcheck
|
|
|
|
reports which files are below the build directory but not in the
|
|
MANIFEST file and vice versa. (See ExtUtils::Manifest::fullcheck() for
|
|
details)
|
|
|
|
=item make skipcheck
|
|
|
|
reports which files are skipped due to the entries in the
|
|
C<MANIFEST.SKIP> file (See ExtUtils::Manifest::skipcheck() for
|
|
details)
|
|
|
|
=item make distclean
|
|
|
|
does a realclean first and then the distcheck. Note that this is not
|
|
needed to build a new distribution as long as you are sure, that the
|
|
MANIFEST file is ok.
|
|
|
|
=item make manifest
|
|
|
|
rewrites the MANIFEST file, adding all remaining files found (See
|
|
ExtUtils::Manifest::mkmanifest() for details)
|
|
|
|
=item make distdir
|
|
|
|
Copies all the files that are in the MANIFEST file to a newly created
|
|
directory with the name C<$(DISTNAME)-$(VERSION)>. If that directory
|
|
exists, it will be removed first.
|
|
|
|
=item make disttest
|
|
|
|
Makes a distdir first, and runs a C<perl Makefile.PL>, a make, and
|
|
a make test in that directory.
|
|
|
|
=item make tardist
|
|
|
|
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
|
|
|
|
Defaults to $(DIST_DEFAULT) which in turn defaults to tardist.
|
|
|
|
=item make uutardist
|
|
|
|
Runs a tardist first and uuencodes the tarfile.
|
|
|
|
=item make shdist
|
|
|
|
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.
|
|
|
|
=item make zipdist
|
|
|
|
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.
|
|
|
|
=item make ci
|
|
|
|
Does a $(CI) and a $(RCS_LABEL) on all files in the MANIFEST file.
|
|
|
|
=back
|
|
|
|
Customization of the dist targets can be done by specifying a hash
|
|
reference to the dist attribute of the WriteMakefile call. The
|
|
following parameters are recognized:
|
|
|
|
CI ('ci -u')
|
|
COMPRESS ('gzip --best')
|
|
POSTOP ('@ :')
|
|
PREOP ('@ :')
|
|
TO_UNIX (depends on the system)
|
|
RCS_LABEL ('rcs -q -Nv$(VERSION_SYM):')
|
|
SHAR ('shar')
|
|
SUFFIX ('.gz')
|
|
TAR ('tar')
|
|
TARFLAGS ('cvf')
|
|
ZIP ('zip')
|
|
ZIPFLAGS ('-r')
|
|
|
|
An example:
|
|
|
|
WriteMakefile( 'dist' => { COMPRESS=>"bzip2", SUFFIX=>".bz2" })
|
|

|
=head2 Disabling an extension
|
|
|
|
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
|
|
|
|
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).
