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
19 Methods always loaded
20 wraplist
21 Converts a list into a string wrapped at approximately 80 columns.
22
23 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
30 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
38 find_perl (override)
39 Use VMS file specification syntax and CLI commands to find and
40 invoke Perl images.
41
42 _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 $Config{startperl} and preserve the
46 shebang line argument for any switches it may contain.
47
48 maybe_command (override)
49 Follows VMS naming conventions for executable files. If the name
50 passed in doesn't exactly match an executable file, appends .Exe
51 (or equivalent) to check for executable image, and .Com to check
52 for DCL procedure. If this fails, checks directories in DCL$PATH
53 and finally Sys$System: for an executable file having the name
54 specified, with or without the .Exe-equivalent suffix.
55
56 pasthru (override)
57 VMS has $(MMSQUALIFIERS) which is a listing of all the original
58 command line options. This is used in every invocation of make in
59 the VMS Makefile so PASTHRU should not be necessary. Using PASTHRU
60 tends to blow commands past the 256 character limit.
61
62 pm_to_blib (override)
63 VMS wants a dot in every file so we can't have one called
64 'pm_to_blib', it becomes 'pm_to_blib.' and MMS/K isn't smart enough
65 to know that when you have a target called 'pm_to_blib' it should
66 look for 'pm_to_blib.'.
67
68 So in VMS its pm_to_blib.ts.
69
70 perl_script (override)
71 If name passed in doesn't specify a readable file, appends .com or
72 .pl and tries again, since it's customary to have file types on all
73 files under VMS.
74
75 replace_manpage_separator
76 Use as separator a character which is legal in a VMS-syntax file
77 name.
78
79 init_DEST
80 (override) Because of the difficulty concatenating VMS filepaths we
81 must pre-expand the DEST* variables.
82
83 init_DIRFILESEP
84 No separator between a directory path and a filename on VMS.
85
86 init_main (override)
87 init_tools (override)
88 Provide VMS-specific forms of various utility commands.
89
90 Sets DEV_NULL to nothing because I don't know how to do it on VMS.
91
92 Changes EQUALIZE_TIMESTAMP to set revision date of target file to
93 one second later than source file, since MMK interprets precisely
94 equal revision dates for a source and target file as a sign that
95 the target needs to be updated.
96
97 init_platform (override)
98 Add PERL_VMS, MM_VMS_REVISION and MM_VMS_VERSION.
99
100 MM_VMS_REVISION is for backwards compatibility before MM_VMS had a
101 $VERSION.
102
103 platform_constants
104 init_VERSION (override)
105 Override the *DEFINE_VERSION macros with VMS semantics. Translate
106 the MAKEMAKER filepath to VMS style.
107
108 constants (override)
109 Fixes up numerous file and directory macros to insure VMS syntax
110 regardless of input syntax. Also makes lists of files comma-
111 separated.
112
113 special_targets
114 Clear the default .SUFFIXES and put in our own list.
115
116 cflags (override)
117 Bypass shell script and produce qualifiers for CC directly (but
118 warn user if a shell script for this extension exists). Fold
119 multiple /Defines into one, since some C compilers pay attention to
120 only one instance of this qualifier on the command line.
121
122 const_cccmd (override)
123 Adds directives to point C preprocessor to the right place when
124 handling #include <sys/foo.h> directives. Also constructs CC
125 command line a bit differently than MM_Unix method.
126
127 tools_other (override)
128 Throw in some dubious extra macros for Makefile args.
129
130 Also keep around the old $(SAY) macro in case somebody's using it.
131
132 init_dist (override)
133 VMSish defaults for some values.
134
135 macro description default
136
137 ZIPFLAGS flags to pass to ZIP -Vu
138
139 COMPRESS compression command to gzip
140 use for tarfiles
141 SUFFIX suffix to put on -gz
142 compressed files
143
144 SHAR shar command to use vms_share
145
146 DIST_DEFAULT default target to use to tardist
147 create a distribution
148
149 DISTVNAME Use VERSION_SYM instead of $(DISTNAME)-$(VERSION_SYM)
150 VERSION for the name
151
152 c_o (override)
153 Use VMS syntax on command line. In particular, $(DEFINE) and
154 $(PERL_INC) have been pulled into $(CCCMD). Also use MM[SK]
155 macros.
156
157 xs_c (override)
158 Use MM[SK] macros.
159
160 xs_o (override)
161 Use MM[SK] macros, and VMS command line for C compiler.
162
163 dlsyms (override)
164 Create VMS linker options files specifying universal symbols for
165 this extension's shareable image, and listing other shareable
166 images or libraries to which it should be linked.
167
168 dynamic_lib (override)
169 Use VMS Link command.
170
171 static_lib (override)
172 Use VMS commands to manipulate object library.
173
174 extra_clean_files
175 Clean up some OS specific files. Plus the temp file used to
176 shorten a lot of commands. And the name mangler database.
177
178 zipfile_target
179 tarfile_target
180 shdist_target
181 Syntax for invoking shar, tar and zip differs from that for Unix.
182
183 install (override)
184 Work around DCL's 255 character limit several times,and use VMS-
185 style command line quoting in a few cases.
186
187 perldepend (override)
188 Use VMS-style syntax for files; it's cheaper to just do it directly
189 here than to have the MM_Unix method call "catfile" repeatedly.
190 Also, if we have to rebuild Config.pm, use MM[SK] to do it.
191
192 makeaperl (override)
193 Undertake to build a new set of Perl images using VMS commands.
194 Since VMS does dynamic loading, it's not necessary to statically
195 link each extension into the Perl image, so this isn't the normal
196 build path. Consequently, it hasn't really been tested, and may
197 well be incomplete.
198
199 maketext_filter (override)
200 Insure that colons marking targets are preceded by space, in order
201 to distinguish the target delimiter from a colon appearing as part
202 of a filespec.
203
204 prefixify (override)
205 prefixifying on VMS is simple. Each should simply be:
206
207 perl_root:[some.dir]
208
209 which can just be converted to:
210
211 volume:[your.prefix.some.dir]
212
213 otherwise you get the default layout.
214
215 In effect, your search prefix is ignored and $Config{vms_prefix} is
216 used instead.
217
218 cd
219 oneliner
220 echo
221 perl trips up on "<foo>" thinking it's an input redirect. So we
222 use the native Write command instead. Besides, its faster.
223
224 quote_literal
225 escape_dollarsigns
226 Quote, don't escape.
227
228 escape_all_dollarsigns
229 Quote, don't escape.
230
231 escape_newlines
232 max_exec_len
233 256 characters.
234
235 init_linker
236 catdir (override)
237 catfile (override)
238 Eliminate the macros in the output to the MMS/MMK file.
239
240 (File::Spec::VMS used to do this for us, but it's being removed)
241
242 eliminate_macros
243 Expands MM[KS]/Make macros in a text string, using the contents of
244 identically named elements of %$self, and returns the result as a
245 file specification in Unix syntax.
246
247 NOTE: This is the canonical version of the method. The version in
248 File::Spec::VMS is deprecated.
249
250 fixpath
251 my $path = $mm->fixpath($path);
252 my $path = $mm->fixpath($path, $is_dir);
253
254 Catchall routine to clean up problem MM[SK]/Make macros. Expands
255 macros in any directory specification, in order to avoid
256 juxtaposing two VMS-syntax directories when MM[SK] is run. Also
257 expands expressions which are all macro, so that we can tell how
258 long the expansion is, and avoid overrunning DCL's command buffer
259 when MM[KS] is running.
260
261 fixpath() checks to see whether the result matches the name of a
262 directory in the current default directory and returns a directory
263 or file specification accordingly. $is_dir can be set to true to
264 force fixpath() to consider the path to be a directory or false to
265 force it to be a file.
266
267 NOTE: This is the canonical version of the method. The version in
268 File::Spec::VMS is deprecated.
269
270 os_flavor
271 VMS is VMS.
