10 Do not use this directly.
11 Instead, use ExtUtils::MM and it will figure out which MM_*
12 class to use for you.
13
15 See ExtUtils::MM_Unix for a documentation of the methods provided
16 there. This package overrides the implementation of these methods, not
17 the semantics.
18 Methods always loaded
20 wraplist
21 Converts a list into a string wrapped at approximately 80 columns.
22 Methods
24 Those methods which override default MM_Unix methods are marked
25 "(override)", while methods unique to MM_VMS are marked "(specific)".
26 For overridden methods, documentation is limited to an explanation of
27 why this method overrides the MM_Unix method; see the ExtUtils::MM_Unix
28 documentation for more details.
29 guess_name (override)
31 Try to determine name of extension being built. We begin with the
32 name of the current directory. Since VMS filenames are case-
33 insensitive, however, we look for a .pm file whose name matches
34 that of the current directory (presumably the 'main' .pm file for
35 this extension), and try to find a "package" statement from which
36 to obtain the Mixed::Case package name.
37 find_perl (override)
39 Use VMS file specification syntax and CLI commands to find and
40 invoke Perl images.
41 _fixin_replace_shebang (override)
43 Helper routine for MM->fixin(), overridden because there's no such
44 thing as an actual shebang line that will be interpreted by the
45 shell, so we just prepend $Config{startperl} and preserve the
46 shebang line argument for any switches it may contain.
47 maybe_command (override)
49 Follows VMS naming conventions for executable files. If the name
50 passed in doesn't exactly match an executable file, appends .Exe
51 (or equivalent) to check for executable image, and .Com to check
52 for DCL procedure. If this fails, checks directories in DCL$PATH
53 and finally Sys$System: for an executable file having the name
54 specified, with or without the .Exe-equivalent suffix.
55 pasthru (override)
57 The list of macro definitions to be passed through must be
58 specified using the /MACRO qualifier and must not add another
59 /DEFINE qualifier. We prepend our own comma here to the contents
60 of $(PASTHRU_DEFINE) because it is often empty and a comma always
61 present in CCFLAGS would generate a missing qualifier value error.
62 pm_to_blib (override)
64 VMS wants a dot in every file so we can't have one called
65 'pm_to_blib', it becomes 'pm_to_blib.' and MMS/K isn't smart enough
66 to know that when you have a target called 'pm_to_blib' it should
67 look for 'pm_to_blib.'.
68 So in VMS its pm_to_blib.ts.
70 perl_script (override)
72 If name passed in doesn't specify a readable file, appends .com or
73 .pl and tries again, since it's customary to have file types on all
74 files under VMS.
75 replace_manpage_separator
77 Use as separator a character which is legal in a VMS-syntax file
78 name.
79 init_DEST
81 (override) Because of the difficulty concatenating VMS filepaths we
82 must pre-expand the DEST* variables.
83 init_DIRFILESEP
85 No separator between a directory path and a filename on VMS.
86 init_main (override)
88 init_tools (override)
89 Provide VMS-specific forms of various utility commands.
90 Sets DEV_NULL to nothing because I don't know how to do it on VMS.
92 Changes EQUALIZE_TIMESTAMP to set revision date of target file to
94 one second later than source file, since MMK interprets precisely
95 equal revision dates for a source and target file as a sign that
96 the target needs to be updated.
97 init_platform (override)
99 Add PERL_VMS, MM_VMS_REVISION and MM_VMS_VERSION.
100 MM_VMS_REVISION is for backwards compatibility before MM_VMS had a
102 $VERSION.
103 platform_constants
105 init_VERSION (override)
106 Override the *DEFINE_VERSION macros with VMS semantics. Translate
107 the MAKEMAKER filepath to VMS style.
108 constants (override)
110 Fixes up numerous file and directory macros to insure VMS syntax
111 regardless of input syntax. Also makes lists of files comma-
112 separated.
113 special_targets
115 Clear the default .SUFFIXES and put in our own list.
116 cflags (override)
118 Bypass shell script and produce qualifiers for CC directly (but
119 warn user if a shell script for this extension exists). Fold
120 multiple /Defines into one, since some C compilers pay attention to
121 only one instance of this qualifier on the command line.
122 const_cccmd (override)
124 Adds directives to point C preprocessor to the right place when
125 handling #include <sys/foo.h> directives. Also constructs CC
126 command line a bit differently than MM_Unix method.
127 tools_other (override)
129 Throw in some dubious extra macros for Makefile args.
130 Also keep around the old $(SAY) macro in case somebody's using it.
132 init_dist (override)
134 VMSish defaults for some values.
135 macro description default
137 ZIPFLAGS flags to pass to ZIP -Vu
139 COMPRESS compression command to gzip
141 use for tarfiles
142 SUFFIX suffix to put on -gz
143 compressed files
144 SHAR shar command to use vms_share
146 DIST_DEFAULT default target to use to tardist
148 create a distribution
149 DISTVNAME Use VERSION_SYM instead of $(DISTNAME)-$(VERSION_SYM)
151 VERSION for the name
152 c_o (override)
154 Use VMS syntax on command line. In particular, $(DEFINE) and
155 $(PERL_INC) have been pulled into $(CCCMD). Also use MM[SK]
156 macros.
157 xs_c (override)
159 Use MM[SK] macros.
160 xs_o (override)
162 Use MM[SK] macros, and VMS command line for C compiler.
163 _xsbuild_replace_macro (override)
165 There is no simple replacement possible since a qualifier and all
166 its subqualifiers must be considered together, so we use our own
167 utility routine for the replacement.
168 _xsbuild_value (override)
170 Convert the extension spec to Unix format, as that's what will
171 match what's in the XSBUILD data structure.
172 dlsyms (override)
174 Create VMS linker options files specifying universal symbols for
175 this extension's shareable image(s), and listing other shareable
176 images or libraries to which it should be linked.
177 xs_obj_opt
179 Override to fixup -o flags.
180 dynamic_lib (override)
182 Use VMS Link command.
183 xs_make_static_lib (override)
185 Use VMS commands to manipulate object library.
186 static_lib_pure_cmd (override)
188 Use VMS commands to manipulate object library.
189 xs_static_lib_is_xs
191 extra_clean_files
192 Clean up some OS specific files. Plus the temp file used to
193 shorten a lot of commands. And the name mangler database.
194 zipfile_target
196 tarfile_target
197 shdist_target
198 Syntax for invoking shar, tar and zip differs from that for Unix.
199 install (override)
201 Work around DCL's 255 character limit several times,and use VMS-
202 style command line quoting in a few cases.
203 perldepend (override)
205 Use VMS-style syntax for files; it's cheaper to just do it directly
206 here than to have the MM_Unix method call "catfile" repeatedly.
207 Also, if we have to rebuild Config.pm, use MM[SK] to do it.
208 makeaperl (override)
210 Undertake to build a new set of Perl images using VMS commands.
211 Since VMS does dynamic loading, it's not necessary to statically
212 link each extension into the Perl image, so this isn't the normal
213 build path. Consequently, it hasn't really been tested, and may
214 well be incomplete.
215 maketext_filter (override)
217 Ensure that colons marking targets are preceded by space, in order
218 to distinguish the target delimiter from a colon appearing as part
219 of a filespec.
220 prefixify (override)
222 prefixifying on VMS is simple. Each should simply be:
223 perl_root:[some.dir]
225 which can just be converted to:
227 volume:[your.prefix.some.dir]
229 otherwise you get the default layout.
231 In effect, your search prefix is ignored and $Config{vms_prefix} is
233 used instead.
234 cd
236 oneliner
237 echo
238 perl trips up on "<foo>" thinking it's an input redirect. So we
239 use the native Write command instead. Besides, it's faster.
240 quote_literal
242 escape_dollarsigns
243 Quote, don't escape.
244 escape_all_dollarsigns
246 Quote, don't escape.
247 escape_newlines
249 max_exec_len
250 256 characters.
251 init_linker
253 catdir (override)
254 catfile (override)
255 Eliminate the macros in the output to the MMS/MMK file.
256 (File::Spec::VMS used to do this for us, but it's being removed)
258 eliminate_macros
260 Expands MM[KS]/Make macros in a text string, using the contents of
261 identically named elements of %$self, and returns the result as a
262 file specification in Unix syntax.
263 NOTE: This is the canonical version of the method. The version in
265 File::Spec::VMS is deprecated.
266 fixpath
268 my $path = $mm->fixpath($path);
269 my $path = $mm->fixpath($path, $is_dir);
270 Catchall routine to clean up problem MM[SK]/Make macros. Expands
272 macros in any directory specification, in order to avoid
273 juxtaposing two VMS-syntax directories when MM[SK] is run. Also
274 expands expressions which are all macro, so that we can tell how
275 long the expansion is, and avoid overrunning DCL's command buffer
276 when MM[KS] is running.
277 fixpath() checks to see whether the result matches the name of a
279 directory in the current default directory and returns a directory
280 or file specification accordingly. $is_dir can be set to true to
281 force fixpath() to consider the path to be a directory or false to
282 force it to be a file.
283 NOTE: This is the canonical version of the method. The version in
285 File::Spec::VMS is deprecated.
286 os_flavor
288 VMS is VMS.
289 is_make_type (override)
291 None of the make types being checked for is viable on VMS, plus our
292 $self->{MAKE} is an unexpanded (and unexpandable) macro whose value
293 is known only to the make utility itself.
294 make_type (override)
296 Returns a suitable string describing the type of makefile being
297 written.
