NAME
       ExtUtils::MM_Unix - methods used by ExtUtils::MakeMaker
SYNOPSIS
       "require ExtUtils::MM_Unix;"
DESCRIPTION
       The methods provided by this package are designed to be used in
       conjunction with ExtUtils::MakeMaker. When MakeMaker writes a Makefile,
       it creates one or more objects that inherit their methods from a
       package "MM". MM itself doesn't provide any methods, but it ISA
       ExtUtils::MM_Unix class. The inheritance tree of MM lets operating
       specific packages take the responsibility for all the methods provided
       by MM_Unix. We are trying to reduce the number of the necessary
       overrides by defining rather primitive operations within
       ExtUtils::MM_Unix.
       If you are going to write a platform specific MM package, please try to
       limit the necessary overrides to primitive methods, and if it is not
       possible to do so, let's work out how to achieve that gain.
       If you are overriding any of these methods in your Makefile.PL (in the
       MY class), please report that to the makemaker mailing list. We are
       trying to minimize the necessary method overrides and switch to data
       driven Makefile.PLs wherever possible. In the long run less methods
       will be overridable via the MY class.
METHODS
       The following description of methods is still under development. Please
       refer to the code for not suitably documented sections and complain
       loudly to the makemaker AT perl.org mailing list.  Better yet, provide a
       patch.
       Not all of the methods below are overridable in a Makefile.PL.
       Overridable methods are marked as (o). All methods are overridable by a
       platform specific MM_*.pm file.
       Cross-platform methods are being moved into MM_Any.  If you can't find
       something that used to be in here, look in MM_Any.
   Methods
       os_flavor
           Simply says that we're Unix.
       c_o (o)
           Defines the suffix rules to compile different flavors of C files to
           object files.
       cflags (o)
           Does very much the same as the cflags script in the perl
           distribution. It doesn't return the whole compiler command line,
           but initializes all of its parts. The const_cccmd method then
           actually returns the definition of the CCCMD macro which uses these
           parts.
       const_cccmd (o)
           Returns the full compiler call for C programs and stores the
           definition in CONST_CCCMD.
       const_config (o)
           Defines a couple of constants in the Makefile that are imported
           from %Config.
       const_loadlibs (o)
           Defines EXTRALIBS, LDLOADLIBS, BSLOADLIBS, LD_RUN_PATH. See
           ExtUtils::Liblist for details.
       constants (o)
             my $make_frag = $mm->constants;
           Prints out macros for lots of constants.
       depend (o)
           Same as macro for the depend attribute.
       init_DEST
             $mm->init_DEST
           Defines the DESTDIR and DEST* variables paralleling the INSTALL*.
       init_dist
             $mm->init_dist;
           Defines a lot of macros for distribution support.

       dist (o)
             my $dist_macros = $mm->dist(%overrides);
           Generates a make fragment defining all the macros initialized in
           init_dist.
           %overrides can be used to override any of the above.
       dist_basics (o)
           Defines the targets distclean, distcheck, skipcheck, manifest,
           veryclean.

             my $dist_make_fragment = $MM->dist_core;
           Puts the targets necessary for 'make dist' together into one make
           fragment.
       dist_target
             my $make_frag = $MM->dist_target;
           Returns the 'dist' target to make an archive for distribution.
           This target simply checks to make sure the Makefile is up-to-date
           and depends on $(DIST_DEFAULT).
       tardist_target
             my $make_frag = $MM->tardist_target;
           Returns the 'tardist' target which is simply so 'make tardist'
           works.  The real work is done by the dynamically named
           tardistfile_target() method, tardist should have that as a
           dependency.
       zipdist_target
             my $make_frag = $MM->zipdist_target;
           Returns the 'zipdist' target which is simply so 'make zipdist'
           works.  The real work is done by the dynamically named
           zipdistfile_target() method, zipdist should have that as a
           dependency.
       tarfile_target
             my $make_frag = $MM->tarfile_target;
           The name of this target is the name of the tarball generated by
           tardist.  This target does the actual work of turning the distdir
           into a tarball.
       zipfile_target
             my $make_frag = $MM->zipfile_target;
           The name of this target is the name of the zip file generated by
           zipdist.  This target does the actual work of turning the distdir
           into a zip file.
       uutardist_target
             my $make_frag = $MM->uutardist_target;
           Converts the tarfile into a uuencoded file
       shdist_target
             my $make_frag = $MM->shdist_target;
           Converts the distdir into a shell archive.
       dlsyms (o)
           Used by some OS' to define DL_FUNCS and DL_VARS and write the *.exp
           files.
           Normally just returns an empty string.
       dynamic_bs (o)
           Defines targets for bootstrap files.
       dynamic_lib (o)
           Defines how to produce the *.so (or equivalent) files.
       exescan
           Deprecated method. Use libscan instead.
       extliblist
           Called by init_others, and calls ext ExtUtils::Liblist. See
           ExtUtils::Liblist for details.
       find_perl
           Finds the executables PERL and FULLPERL
       fixin
             $mm->fixin(@files);
           Inserts the sharpbang or equivalent magic number to a set of
           @files.
       force (o)
           Writes an empty FORCE: target.
       guess_name
           Guess the name of this package by examining the working directory's
           name. MakeMaker calls this only if the developer has not supplied a
           NAME attribute.
       has_link_code
           Returns true if C, XS, MYEXTLIB or similar objects exist within
           this object that need a compiler. Does not descend into
           subdirectories as needs_linking() does.
       init_dirscan
           Scans the directory structure and initializes DIR, XS, XS_FILES, C,
           C_FILES, O_FILES, H, H_FILES, PL_FILES, EXE_FILES.
           Called by init_main.
       init_MANPODS

           XS_VERSION.
       init_tools
           Initializes tools to use their common (and faster) Unix commands.
       init_linker
           Unix has no need of special linker flags.
       init_PERL
               $mm->init_PERL;
           Called by init_main.  Sets up ABSPERL, PERL, FULLPERL and all the
           *PERLRUN* permutations.
               PERL is allowed to be miniperl
               FULLPERL must be a complete perl
               ABSPERL is PERL converted to an absolute path
               *PERLRUN contains everything necessary to run perl, find it's
                    libraries, etc...
               *PERLRUNINST is *PERLRUN + everything necessary to find the
                    modules being built.
       init_platform
       platform_constants
           Add MM_Unix_VERSION.
       init_PERM
             $mm->init_PERM
           Called by init_main.  Initializes PERL_*
       init_xs
               $mm->init_xs
           Sets up macros having to do with XS code.  Currently just
           INST_STATIC, INST_DYNAMIC and INST_BOOT.
       install (o)
           Defines the install target.
       installbin (o)
           Defines targets to make and to install EXE_FILES.
       linkext (o)
           Defines the linkext target which in turn defines the LINKTYPE.
       lsdir
           Takes as arguments a directory name and a regular expression.
           Returns all entries in the directory that match the regular
           expression.
       macro (o)
           Simple subroutine to insert the macros defined by the macro
           attribute into the Makefile.
       makeaperl (o)
           Called by staticmake. Defines how to write the Makefile to produce
           a static new perl.
           By default the Makefile produced includes all the static extensions
           in the perl library. (Purified versions of library files, e.g.,
           DynaLoader_pure_p1_c0_032.a are automatically ignored to avoid link
           errors.)
       makefile (o)
           Defines how to rewrite the Makefile.
       maybe_command
           Returns true, if the argument is likely to be a command.
       needs_linking (o)
           Does this module need linking? Looks into subdirectory objects (see
           also has_link_code())
       parse_abstract
           parse a file and return what you think is the ABSTRACT
       parse_version
               my $version = MM->parse_version($file);
           Parse a $file and return what $VERSION is set to by the first
           assignment.  It will return the string "undef" if it can't figure
           out what $VERSION is. $VERSION should be for all to see, so "our
           $VERSION" or plain $VERSION are okay, but "my $VERSION" is not.
           "<package Foo VERSION"> is also checked for.  The first version
           declaration found is used, but this may change as it differs from
           how Perl does it.
           parse_version() will try to "use version" before checking for
           $VERSION so the following will work.
               $VERSION = qv(1.2.3);
       pasthru (o)
           Defines the string that is passed to recursive make calls in
           subdirectories.
       perl_script
           Takes one argument, a file name, and returns the file name, if the
           argument is likely to be a perl script. On MM_Unix this is true for
           any ordinary, readable file.
       perldepend (o)
           Defines the dependency from all *.h files that come with the perl
           distribution.
       pm_to_blib
           Defines target that copies all files in the hash PM to their
           destination and autosplits them. See "DESCRIPTION" in
           ExtUtils::Install
       post_constants (o)
           Returns an empty string per default. Dedicated to overrides from
           within Makefile.PL after all constants have been defined.
       post_initialize (o)
           Returns an empty string per default. Used in Makefile.PLs to add
           some chunk of text to the Makefile after the object is initialized.
       postamble (o)
           Returns an empty string. Can be used in Makefile.PLs to write some
           text to the Makefile at the end.
       ppd Defines target that creates a PPD (Perl Package Description) file
           for a binary distribution.
       prefixify
             $MM->prefixify($var, $prefix, $new_prefix, $default);
           Using either $MM->{uc $var} || $Config{lc $var}, it will attempt to
           replace it's $prefix with a $new_prefix.
           Should the $prefix fail to match AND a PREFIX was given as an
           argument to WriteMakefile() it will set it to the $new_prefix +
           $default.  This is for systems whose file layouts don't neatly fit
           into our ideas of prefixes.
           This is for heuristics which attempt to create directory structures
           that mirror those of the installed perl.
           For example:
               $MM->prefixify('installman1dir', '/usr', '/home/foo', 'man/man1');
           this will attempt to remove '/usr' from the front of the
           $MM->{INSTALLMAN1DIR} path (initializing it to
           $Config{installman1dir} if necessary) and replace it with
           '/home/foo'.  If this fails it will simply use
           '/home/foo/man/man1'.
       processPL (o)
           Defines targets to run *.PL files.
       quote_paren
           Backslashes parentheses "()" in command line arguments.  Doesn't
           handle recursive Makefile "$(...)" constructs, but handles simple
           ones.
       replace_manpage_separator
             my $man_name = $MM->replace_manpage_separator($file_path);
           Takes the name of a package, which may be a nested package, in the
           form 'Foo/Bar.pm' and replaces the slash with "::" or something
           else safe for a man page file name.  Returns the replacement.
       cd
       oneliner
       quote_literal
       escape_newlines
       max_exec_len
           Using POSIX::ARG_MAX.  Otherwise falling back to 4096.
       static (o)
           Defines the static target.
       static_lib (o)
           Defines how to produce the *.a (or equivalent) files.
       staticmake (o)
           Calls makeaperl.
       subdir_x (o)
           Helper subroutine for subdirs
       subdirs (o)
           Defines targets to process subdirectories.
       test (o)
           Defines the test targets.
       test_via_harness (override)
           For some reason which I forget, Unix machines like to have
           PERL_DL_NONLAZY set for tests.
       test_via_script (override)
           Again, the PERL_DL_NONLAZY thing.
       tool_xsubpp (o)
           Determines typemaps, xsubpp version, prototype behaviour.
       all_target
           Build man pages, too
       top_targets (o)
           Defines the targets all, subdirs, config, and O_FILES
       writedoc
           Obsolete, deprecated method. Not used since Version 5.21.
       xs_c (o)
           Defines the suffix rules to compile XS files to C.
       xs_cpp (o)
           Defines the suffix rules to compile XS files to C++.
       xs_o (o)
           Defines suffix rules to go from XS to object files directly. This
           is only intended for broken make implementations.
