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.

xs_obj_opt

Takes the object file as an argument, and returns the portion of compile command-line that will output to the specified object file.

dbgoutflag

Returns a CC flag that tells the CC to emit a separate debugging symbol file when compiling an object file.

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)

Sets SHELL if needed, then 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.

                just after CI is run

  DIST_CP       $how argument to manicopy()     best
                when the distdir is created

  DIST_DEFAULT  default target to use to        tardist
                create a distribution

  DISTVNAME     name of the resulting archive   $(DISTNAME)-$(VERSION)
                (minus suffixes)
    

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.

dist_ci (o)

Defines a check in target for RCS.

dist_core (o)

  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.

xs_dynamic_lib_macros

Defines the macros for the "dynamic_lib" section.

xs_make_dynamic_lib

Defines the recipes for the "dynamic_lib" section.

exescan

Deprecated method. Use libscan instead.

extliblist

Called by init_others, and calls ext ExtUtils::Liblist. See ExtUtils::Liblist for details.

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

Determines if man pages should be generated and initializes MAN1PODS and MAN3PODS as appropriate.

init_MAN1PODS

Initializes MAN1PODS from the list of EXE_FILES.

init_MAN3PODS

Initializes MAN3PODS from the list of PM files.

init_PM

Initializes PMLIBDIRS and PM from PMLIBDIRS.

init_DIRFILESEP

Using / for Unix. Called by init_main.

init_main

Initializes AR, AR_STATIC_ARGS, BASEEXT, CONFIG, DISTNAME, DLBASE, EXE_EXT, FULLEXT, FULLPERL, FULLPERLRUN, FULLPERLRUNINST, INST_*, INSTALL*, INSTALLDIRS, 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_SYM, 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.)

xs_static_lib_is_xs (o)

Called by a utility method of makeaperl. Checks whether a given file is an XS library by seeing whether it defines any symbols starting with "boot_" (with an optional leading underscore - needed on MacOS).

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. The variables like "PASTHRU_DEFINE" are used in each level, and passed downwards on the command-line with e.g. the value of that level's DEFINE. Example:

    # Level 0 has DEFINE = -Dfunky
    # This code will define level 0's PASTHRU=PASTHRU_DEFINE="$(DEFINE)
    #     $(PASTHRU_DEFINE)"
    # Level 0's $(CCCMD) will include macros $(DEFINE) and $(PASTHRU_DEFINE)
    # So will level 1's, so when level 1 compiles, it will get right values
    # And so ad infinitum
    

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

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.

specify_shell

Specify SHELL if needed - not done on Unix.

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

Quotes macro literal value suitable for being used on a command line so that when expanded by make, will be received by command as given to this method:

  my $quoted = $mm->quote_literal(q{it isn't});
  # returns:
  #   'it isn'\''t'
  print MAKEFILE "target:\n\techo $quoted\n";
  # when run "make target", will output:
  #   it isn't
    

escape_newlines

max_exec_len

Using POSIX::ARG_MAX. Otherwise falling back to 4096.

static (o)

Defines the static target.

xs_make_static_lib

Defines the recipes for the "static_lib" section.

static_lib_closures

Records "$(EXTRALIBS)" in extralibs.ld and $(PERL_SRC)/ext.libs.

static_lib_fixtures

Handles copying "$(MYEXTLIB)" as starter for final static library that then gets added to.

static_lib_pure_cmd

Defines how to run the archive utility.

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 was originally only intended for broken make implementations, but is now necessary for per-XS file under "XSMULTI", since each XS file might have an individual "$(VERSION)".
