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 ExtU- tils::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 mailing list. 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 (See ExtUtils::MM_VMS) and ExtUtils::MM_OS2). SelfLoaded methods 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. clean (o) Defines the clean target. 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) Initializes lots of constants and .SUFFIXES and .PHONY depend (o) Same as macro for the depend attribute. dir_target (o) Takes an array of directories that need to exist and returns a Makefile entry for a .exists file in these directories. Returns nothing, if the entry has already been processed. We're helpless though, if the same directory comes as $(FOO) _and_ as "bar". Both of them get an entry, that's why we use "::". dist (o) Defines a lot of macros for distribution support. dist_basics (o) Defines the targets distclean, distcheck, skipcheck, manifest, veryclean. dist_ci (o) Defines a check in target for RCS. dist_core (o) Defines the targets dist, tardist, zipdist, uutardist, shdist dist_dir Defines the scratch directory target that will hold the distribution before tar-ing (or shar-ing). dist_test Defines a target that produces the distribution in the scratchdirectory, and runs 'perl Makefile.PL; make ;make test' in that subdirec- tory. dlsyms (o) Used by AIX and VMS to define DL_FUNCS and DL_VARS and write the *.exp files. dynamic (o) Defines the dynamic target. 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 find_tests my $test = $mm->find_tests; Returns a string suitable for feeding to the shell to return all tests in t/*.t. Methods to actually produce chunks of text for the Makefile The methods here are called for each MakeMaker object in the order specified by @ExtUtils::MakeMaker::MM_Sections. fixin $mm->fixin(@files); Inserts the sharpbang or equivalent magic number to a set of @files. force (o) Just writes FORCE: 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 Initializes DIR, XS, PM, C, O_FILES, H, PL_FILES, MAN*PODS, EXE_FILES. init_main Initializes AR, AR_STATIC_ARGS, BASEEXT, CONFIG, DISTNAME, DLBASE, EXE_EXT, FULLEXT, FULLPERL, FULLPERLRUN, FULLPERLRUNINST, INST_*, INSTALL*, INSTALLDIRS, LD, LIB_EXT, LIBPERL_A, MAP_TARGET, NAME, OBJ_EXT, PARENT_NAME, PERL, PERL_ARCHLIB, PERL_INC, PERL_LIB, PERL_SRC, PERLRUN, PERLRUNINST, PREFIX, VERSION, VERSION_FROM, VERSION_SYM, XS_VERSION. init_others Initializes EXTRALIBS, BSLOADLIBS, LDLOADLIBS, LIBS, LD_RUN_PATH, OBJECT, BOOTDEP, PERLMAINCC, LDFROM, LINKTYPE, NOOP, FIRST_MAKEFILE, MAKEFILE, NOECHO, RM_F, RM_RF, TEST_F, TOUCH, CP, MV, CHMOD, UMASK_NULL init_INST $mm->init_INST; Called by init_main. Sets up all INST_* variables. init_INSTALL $mm->init_INSTALL; Called by init_main. Sets up all INSTALL_* variables (except INSTALLDIRS) and PREFIX. 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_PERM $mm->init_PERM Called by init_main. Initializes PERL_* install (o) Defines the install target. installbin (o) Defines targets to make and to install EXE_FILES. libscan (o) Takes a path to a file that is found by init_dirscan and returns false if we don't want to include this file in the library. Mainly used to exclude RCS, CVS, and SCCS directories from installation. 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. manifypods (o) Defines targets and routines to translate the pods into manpages and put them into the INST_* directories. maybe_command Returns true, if the argument is likely to be a command. maybe_command_in_dirs method under development. Not yet used. Ask Ilya :-) needs_linking (o) Does this module need linking? Looks into subdirectory objects (see also has_link_code()) nicetext misnamed method (will have to be changed). The MM_Unix method just returns the argument without further processing. On VMS used to insure that colons marking targets are preceded by space - most Unix Makes don't need this, but it's necessary under VMS to distinguish the target delimiter from a colon appearing as part of a filespec. parse_abstract parse a file and return what you think is the ABSTRACT parse_version parse a file and return what you think is $VERSION in this file set to. 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. 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. perm_rw (o) Returns the attribute "PERM_RW" or the string 644. Used as the string that is passed to the "chmod" command to set the permissions for read/writeable files. MakeMaker chooses 644 because it has turned out in the past that relying on the umask provokes hard-to-track bug reports. When the return value is used by the perl function "chmod", it is interpreted as an octal value. perm_rwx (o) Returns the attribute "PERM_RWX" or the string 755, i.e. the string that is passed to the "chmod" command to set the permissions for exe- cutable files. See also perl_rw. 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 it sill simply set it to the $new_prefix + $default. 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 $Config{installman1dir} if neces- sary) and replace it with '/home/foo'. If this fails it will simply use '/home/foo/man/man1'. processPL (o) Defines targets to run *.PL files. quote_paren Backslashes parentheses "()" in command line arguments. Doesn't handle recursive Makefile "$(...)" constructs, but handles simple ones. realclean (o) Defines the realclean target. 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. 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_autosplit (o) Defines a simple perl call that runs autosplit. May be deprecated by pm_to_blib soon. tools_other (o) Defines SHELL, LD, TOUCH, CP, MV, RM_F, RM_RF, CHMOD, UMASK_NULL in the Makefile. Also defines the perl programs MKPATH, WARN_IF_OLD_PACKLIST, MOD_INSTALL. DOC_INSTALL, and UNINSTALL. tool_xsubpp (o) Determines typemaps, xsubpp version, prototype behaviour. 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. perl_archive This is internal method that returns path to libperl.a equivalent to be linked to dynamic extensions. UNIX does not have one but other OSs might have one. perl_archive_after This is an internal method that returns path to a library which should be put on the linker command line after the external libraries to be linked to dynamic extensions. This may be needed if the linker is one-pass, and Perl includes some overrides for C RTL functions, such as malloc(). export_list This is internal method that returns name of a file that is passed to linker to define symbols to be exported. UNIX does not have one but OS2 and Win32 do. SEE ALSO
