- 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- most probably outdated.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.

- =head1 NAME
-
- ExtUtils::MakeMaker - create an extension Makefile
-
- =head1 SYNOPSIS
-
- use ExtUtils::MakeMaker;
-
- WriteMakefile( ATTRIBUTE => VALUE [, ...] );
-
- =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 execute the script with the
- proper set of perl C<-I> options.
-
- MakeMaker also checks for any files matching glob("t/*.t"). It will
- execute all matching files in alphabetical order via the
- L<Test::Harness> module with the C<-I> switches set correctly.
-
- If you'd like to see the raw output of your tests, set the
- C<TEST_VERBOSE> variable to true.
-
- make test TEST_VERBOSE=1
-
- =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 the 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 the 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 vendor
-
- PREFIX SITEPREFIX VENDORPREFIX
- INST_ARCHLIB INSTALLARCHLIB INSTALLSITEARCH INSTALLVENDORARCH
- INST_LIB INSTALLPRIVLIB INSTALLSITELIB INSTALLVENDORLIB
- INST_BIN INSTALLBIN INSTALLSITEBIN INSTALLVENDORBIN
- INST_SCRIPT INSTALLSCRIPT INSTALLSCRIPT INSTALLSCRIPT
- INST_MAN1DIR INSTALLMAN1DIR INSTALLSITEMAN1DIR INSTALLVENDORMAN1DIR
- INST_MAN3DIR INSTALLMAN3DIR INSTALLSITEMAN3DIR INSTALLVENDORMAN3DIR
-
- 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 $/, @INC'
-
-
- =head2 PREFIX and LIB attribute
-
- PREFIX and LIB can be used to set several INSTALL* attributes in one
- go. The quickest way to install a module in a non-standard place might
- be
-
- perl Makefile.PL PREFIX=~
-
- This will install all files in the module under your home directory,
- with man pages and libraries going into an appropriate place (usually
- ~/man and ~/lib).
-
- Another way to specify many INSTALL directories with a single
- parameter is LIB.
-
- perl Makefile.PL LIB=~/lib
-
- This will install the module's architecture-independent files into
- ~/lib, the architecture-dependent files into ~/lib/$archname.
-
- 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:
-
- =over 4
-
- =item *
-
- setting LIB overrides any setting of INSTALLPRIVLIB, INSTALLARCHLIB,
- INSTALLSITELIB, INSTALLSITEARCH (and they are not affected by PREFIX);
-
- =item *
-
- without LIB, setting PREFIX replaces the initial C<$Config{prefix}>
- part of those INSTALL* arguments, even if the latter are explicitly
- set (but are set to still start with C<$Config{prefix}>).
-
- =back
-
- If the user has superuser privileges, and is not working on AFS 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 = $archlibexp
- INST_LIB = ./blib/lib
- INST_ARCHLIB = ./blib/arch
-
- If perl has not yet been installed then PERL_SRC can be defined on the
- command line as shown in the previous section.
-
-
- =head2 Which architecture dependent directory?
-
- If you don't want to keep the defaults for the INSTALL* macros,
- MakeMaker helps you to minimize the typing needed: the usual
- relationship between INSTALLPRIVLIB and INSTALLARCHLIB is determined
- by Configure at perl compilation time. MakeMaker supports the user who
- sets INSTALLPRIVLIB. If INSTALLPRIVLIB is set, but INSTALLARCHLIB not,
- then MakeMaker defaults the latter to be the same subdirectory of
- INSTALLPRIVLIB as Configure decided for the counterparts in %Config ,
- otherwise it defaults to INSTALLPRIVLIB. The same relationship holds
- for INSTALLSITELIB and INSTALLSITEARCH.
-
- MakeMaker gives you much more freedom than needed to configure
- internal variables and get different results. It is worth to mention,
- that make(1) also lets you configure most of the variables that are
- used in the Makefile. But in the majority of situations this will not
- be necessary, and should only be done if the author of a package
- recommends it (or you know what you're doing).
-
- =head2 Using Attributes and Parameters
-
- The following attributes may be specified as arguments to WriteMakefile()
- or as NAME=VALUE pairs on the command line.
-
- =over 2
-
- =item ABSTRACT
-
- One line description of the module. Will be included in PPD file.
-
- =item ABSTRACT_FROM
-
- Name of the file that contains the package description. MakeMaker looks
- for a line in the POD matching /^($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 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, 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.
-
- =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
-
- These directories get the man pages at 'make install' time if
- INSTALLDIRS=site (default). Defaults to
- $(SITEPREFIX)/man/man$(MAN*EXT).
-
- If set to 'none', no man pages will be installed.
-
- =item INSTALLVENDORARCH
-
- Used by 'make install', which copies files from INST_ARCHLIB to this
- directory if INSTALLDIRS is set to vendor.
-
- =item INSTALLVENDORBIN
-
- Used by 'make install', which copies files from INST_BIN to this
- directory if INSTALLDIRS is set to vendor.
-
- =item INSTALLVENDORLIB
-
- 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).
-
- If set to 'none', no man pages will be installed.
-
- =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_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/script", just to have a dummy location during
- testing. make install will copy the files in INST_SCRIPT to
- INSTALLSCRIPT.
-
- =item LDDLFLAGS
-
- Any special flags that might need to be passed to ld to create a
- shared library suitable for dynamic loading. It is up to the makefile
- to use it. (See L<Config/lddlflags>)
-
- Defaults to $Config{lddlflags}.
-
- =item LDFROM
-
- Defaults to "$(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 should only be set at C<perl Makefile.PL> time but is allowed as a
- MakeMaker argument. It has the effect of setting both INSTALLPRIVLIB
- and INSTALLSITELIB to that value regardless any explicit setting of
- those arguments (or of PREFIX). INSTALLARCHLIB and INSTALLSITEARCH
- are set to the corresponding architecture subdirectory.
-
- =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 that assigns to *.pm and *.pod files the files into which the
- manpages are to be written. MakeMaker parses all *.pod and *.pm files
- for POD directives. Files that contain POD will be the default keys of
- the MAN3PODS hashref. These will then be converted to man pages during
- C<make> and will be installed during C<make install>.
-
- =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"
-
- (Where BASEEXT is the last component of NAME, and OBJ_EXT is $Config{obj_ext}.)
-
- =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 PERL_CORE
-
- Set only when MakeMaker is building the extensions of the Perl core
- distribution.
-
- =item PERLMAINCC
-
- The call to the program that is able to compile perlmain.c. Defaults
- to $(CC).
-
- =item PERL_ARCHLIB
-
- Same as for PERL_LIB, but for architecture dependent files.
-
- Used only when MakeMaker is building the extensions of the Perl core
- distribution (because normally $(PERL_ARCHLIB) is automatically in @INC,
- and adding it would get in the way of PERL5LIB).
-
- =item PERL_LIB
-
- Directory containing the Perl library to use.
-
- Used only when MakeMaker is building the extensions of the Perl core
- distribution (because normally $(PERL_LIB) is automatically in @INC,
- and adding it would get in the way of PERL5LIB).
-
- =item PERL_MALLOC_OK
-
- defaults to 0. Should be set to TRUE if the extension can work with
- the memory allocation routines substituted by the Perl malloc() subsystem.
- This should be applicable to most extensions with exceptions of those
-
- =over 4
-
- =item *
-
- with bugs in memory allocations which are caught by Perl's malloc();
-
- =item *
-
- which interact with the memory allocator in other ways than via
- malloc(), realloc(), free(), calloc(), sbrk() and brk();
-
- =item *
-
- which rely on special alignment which is not provided by Perl's malloc().
-
- =back
-
- B<NOTE.> Negligence to set this flag in I<any one> of loaded extension
- nullifies many advantages of Perl's malloc(), such as better usage of
- system resources, error detection, memory usage reporting, catchable failure
- of memory allocations, etc.
-
- =item PERLRUN
-
- Use this instead of $(PERL) when you wish to run perl. It will set up
- extra necessary flags for you.
-
- =item PERLRUNINST
-
- Use this instead of $(PERL) when you wish to run perl to work with
- modules. It will add things like -I$(INST_ARCH) and other necessary
- flags so perl can see the modules you're about to install.
-
- =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.
-
- (Where BASEEXT is the last component of NAME.)
-
- =item PM_FILTER
-
- A filter program, in the traditional Unix sense (input from stdin, output
- to stdout) that is passed on each .pm file during the build (in the
- pm_to_blib() phase). It is empty by default, meaning no filtering is done.
-
- Great care is necessary when defining the command if quoting needs to be
- done. For instance, you would need to say:
-
- {'PM_FILTER' => 'grep -v \\"^\\#\\"'}
-
- to remove all the leading coments on the fly during the build. The
- extra \\ are necessary, unfortunately, because this variable is interpolated
- within the context of a Perl program built on the command line, and double
- quotes are what is used with the -e switch to build that command line. The
- # is escaped for the Makefile, since what is going to be generated will then
- be:
-
- PM_FILTER = grep -v \"^\#\"
-
- Without the \\ before the #, we'd have the start of a Makefile comment,
- and the macro would be incorrectly defined.
-
- =item POLLUTE
-
- Release 5.005 grandfathered old global symbol names by providing preprocessor
- macros for extension source compatibility. As of release 5.6, these
- preprocessor definitions are not available by default. The POLLUTE flag
- specifies that the old names should still be defined:
-
- perl Makefile.PL POLLUTE=1
-
- Please inform the module author if this is necessary to successfully install
- a module under 5.6 or later.
-
- =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
-
- This overrides all the default install locations. Man pages,
- libraries, scripts, etc... MakeMaker will try to make an educated
- guess about where to place things under the new PREFIX based on your
- Config defaults. Failing that, it will fall back to a structure
- which should be sensible for your platform.
-
- If you specify LIB or any INSTALL* variables they will not be effected
- by the PREFIX.
-
- Defaults to $Config{installprefixexp}.
-
- =item PREREQ_FATAL
-
- Bool. If this parameter is true, failing to have the required modules
- (or the right versions thereof) will be fatal. perl Makefile.PL will die
- with the proper message.
-
- Note: see L<Test::Harness> for a shortcut for stopping tests early if
- you are missing dependencies.
-
- Do I<not> use this parameter for simple requirements, which could be resolved
- at a later time, e.g. after an unsuccessful B<make test> of your module.
-
- It is I<extremely> rare to have to use C<PREREQ_FATAL> at all!
-
- =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 PREREQ_PRINT
-
- Bool. If this parameter is true, the prerequisites will be printed to
- stdout and MakeMaker will exit. The output format is
-
- $PREREQ_PM = {
- 'A::B' => Vers1,
- 'C::D' => Vers2,
- ...
- };
-
- =item PRINT_PREREQ
-
- RedHatism for C<PREREQ_PRINT>. The output format is different, though:
-
- perl(A::B)>=Vers1 perl(C::D)>=Vers2 ...
-
- =item SITEPREFIX
-
- Like PREFIX, but only for the site install locations.
-
- Defaults to PREFIX (if set) or $Config{siteprefixexp}. Perls prior to
- 5.6.0 didn't have an explicit siteprefix in the Config. In those
- cases $Config{installprefix} will be used.
-
- =item SKIP
-
- Arrayref. E.g. [qw(name1 name2)] skip (do not write) sections of the
- Makefile. Caution! Do not use the SKIP attribute for the negligible
- 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 VENDORPREFIX
-
- Like PREFIX, but only for the vendor install locations.
-
- Defaults to PREFIX (if set) or $Config{vendorprefixexp}
-
- =item VERBINST
-
- If true, make install will be verbose
-
- =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: 1.63 $ ' =~ /\$Revision:\s+([^\s]+)/;
- $FOO::VERSION = '1.10';
- *FOO::VERSION = \'1.11';
- our $VERSION = 1.2.3; # new for perl5.6.0
-
- but these will fail:
-
- my $VERSION = '1.01';
- local $VERSION = '1.02';
- local $FOO::VERSION = '1.30';
-
- (Putting C<my> or C<local> on the preceding line will work o.k.)
-
- The file named in VERSION_FROM is not added as a dependency to
- Makefile. This is not really correct, but it would be a major pain
- during development to have to rewrite the Makefile for any smallish
- change in that file. If you want to make sure that the Makefile
- contains the correct VERSION macro after any change of the file, you
- would have to do something like
-
- depend => { Makefile => '$(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.
-
- =back
-
- =head2 Additional lowercase attributes
-
- can be used to pass parameters to the methods which implement that
- part of the Makefile.
-
- =over 2
-
- =item clean
-
- {FILES => "*.xyz foo"}
-
- =item depend
-
- {ANY_TARGET => ANY_DEPENDECY, ...}
-
- (ANY_TARGET must not be given a double-colon rule by MakeMaker.)
-
- =item dist
-
- {TARFLAGS => 'cvfF', COMPRESS => 'gzip', SUFFIX => '.gz',
- SHAR => 'shar -m', DIST_CP => 'ln', ZIP => '/bin/zip',
- 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'.
-
- =item dynamic_lib
-
- {ARMAYBE => 'ar', OTHERLDFLAGS => '...', INST_DYNAMIC_DEP => '...'}
-
- =item linkext
-
- {LINKTYPE => 'static', 'dynamic' or ''}
-
- NB: Extensions that have nothing but *.pm files had to say
-
- {LINKTYPE => ''}
-
- with Pre-5.0 MakeMakers. Since version 5.00 of MakeMaker such a line
- can be deleted safely. MakeMaker recognizes when there's nothing to
- be linked.
-
- =item macro
-
- {ANY_MACRO => ANY_VALUE, ...}
-
- =item realclean
-
- {FILES => '$(INST_ARCHAUTODIR)/*.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 subroutine 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:
-
- package MY; # so that "SUPER" works right
- sub c_o {
- 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<makemaker@perl.org>
-
- 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 {
- return <<'MAKE_FRAG';
- $(MYEXTLIB): sdbm/Makefile
- cd sdbm && $(MAKE) all
-
- MAKE_FRAG
- }
-
- =head2 The End Of Cargo Cult Programming
-
- WriteMakefile() now does some basic sanity checks on its parameters to
- protect against typos and malformatted values. This means some things
- which happened to work in the past will now throw warnings and
- possibly produce internal errors.
-
- Some of the most common mistakes:
-
- =over 2
-
- =item C<<MAN3PODS => ' '>>
-
- This is commonly used to supress the creation of man pages. MAN3PODS
- takes a hash ref not a string, but the above worked by accident in old
- versions of MakeMaker.
-
- The correct code is C<<MAN3PODS => { }>>.
-
- =back
-
-
- =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).
-
- =head1 ENVIRONMENT
-
- =over 8
-
- =item PERL_MM_OPT
-
- Command line options used by C<MakeMaker-E<gt>new()>, and thus by
- C<WriteMakefile()>. The string is split on whitespace, and the result
- is processed before any actual command line arguments are processed.
-
- =item PERL_MM_USE_DEFAULT
-
- If set to a true value then MakeMaker's prompt function will
- always return the default without waiting for user input.
