132 | .TH ExtUtils::MM_VMS 3 "2001-09-21" "perl v5.8.8" "Perl Programmers Reference Guide" | |
133 | .SH "NAME" | |
134 | ExtUtils::MM_VMS \- methods to override UN*X behaviour in ExtUtils::MakeMaker | |
135 | .SH "SYNOPSIS" | |
136 | .IX Header "SYNOPSIS" | |
137 | .Vb 3 | |
138 | \& Do not use this directly. | |
139 | \& Instead, use ExtUtils::MM and it will figure out which MM_* | |
140 | \& class to use for you. | |
141 | .Ve | |
142 | .SH "DESCRIPTION" | |
143 | .IX Header "DESCRIPTION" | |
144 | See ExtUtils::MM_Unix for a documentation of the methods provided | |
145 | there. This package overrides the implementation of these methods, not | |
146 | the semantics. | |
147 | .Sh "Methods always loaded" | |
148 | .IX Subsection "Methods always loaded" | |
149 | .IP "wraplist" 4 | |
150 | .IX Item "wraplist" | |
151 | Converts a list into a string wrapped at approximately 80 columns. | |
152 | .Sh "Methods" | |
153 | .IX Subsection "Methods" | |
154 | Those methods which override default MM_Unix methods are marked | |
155 | \&\*(L"(override)\*(R", while methods unique to \s-1MM_VMS\s0 are marked \*(L"(specific)\*(R". | |
156 | For overridden methods, documentation is limited to an explanation | |
157 | of why this method overrides the MM_Unix method; see the ExtUtils::MM_Unix | |
158 | documentation for more details. | |
159 | .IP "guess_name (override)" 4 | |
160 | .IX Item "guess_name (override)" | |
161 | Try to determine name of extension being built. We begin with the name | |
162 | of the current directory. Since \s-1VMS\s0 filenames are case\-insensitive, | |
163 | however, we look for a \fI.pm\fR file whose name matches that of the current | |
164 | directory (presumably the 'main' \fI.pm\fR file for this extension), and try | |
165 | to find a \f(CW\*(C`package\*(C'\fR statement from which to obtain the Mixed::Case | |
166 | package name. | |
167 | .IP "find_perl (override)" 4 | |
168 | .IX Item "find_perl (override)" | |
169 | Use \s-1VMS\s0 file specification syntax and \s-1CLI\s0 commands to find and | |
170 | invoke Perl images. | |
171 | .IP "maybe_command (override)" 4 | |
172 | .IX Item "maybe_command (override)" | |
173 | Follows \s-1VMS\s0 naming conventions for executable files. | |
174 | If the name passed in doesn't exactly match an executable file, | |
175 | appends \fI.Exe\fR (or equivalent) to check for executable image, and \fI.Com\fR | |
176 | to check for \s-1DCL\s0 procedure. If this fails, checks directories in \s-1DCL$PATH\s0 | |
177 | and finally \fISys$System:\fR for an executable file having the name specified, | |
178 | with or without the \fI.Exe\fR\-equivalent suffix. | |
179 | .IP "pasthru (override)" 4 | |
180 | .IX Item "pasthru (override)" | |
181 | \&\s-1VMS\s0 has $(\s-1MMSQUALIFIERS\s0) which is a listing of all the original command line | |
182 | options. This is used in every invokation of make in the \s-1VMS\s0 Makefile so | |
183 | \&\s-1PASTHRU\s0 should not be necessary. Using \s-1PASTHRU\s0 tends to blow commands past | |
184 | the 256 character limit. | |
185 | .IP "pm_to_blib (override)" 4 | |
186 | .IX Item "pm_to_blib (override)" | |
187 | \&\s-1VMS\s0 wants a dot in every file so we can't have one called 'pm_to_blib', | |
188 | it becomes 'pm_to_blib.' and \s-1MMS/K\s0 isn't smart enough to know that when | |
189 | you have a target called 'pm_to_blib' it should look for 'pm_to_blib.'. | |
190 | .Sp | |
191 | So in \s-1VMS\s0 its pm_to_blib.ts. | |
192 | .IP "perl_script (override)" 4 | |
193 | .IX Item "perl_script (override)" | |
194 | If name passed in doesn't specify a readable file, appends \fI.com\fR or | |
195 | \&\fI.pl\fR and tries again, since it's customary to have file types on all files | |
196 | under \s-1VMS\s0. | |
197 | .IP "replace_manpage_separator" 4 | |
198 | .IX Item "replace_manpage_separator" | |
199 | Use as separator a character which is legal in a VMS-syntax file name. | |
200 | .IP "init_DEST" 4 | |
201 | .IX Item "init_DEST" | |
202 | (override) Because of the difficulty concatenating \s-1VMS\s0 filepaths we | |
203 | must pre-expand the DEST* variables. | |
204 | .IP "init_DIRFILESEP" 4 | |
205 | .IX Item "init_DIRFILESEP" | |
206 | No seperator between a directory path and a filename on \s-1VMS\s0. | |
207 | .IP "init_main (override)" 4 | |
208 | .IX Item "init_main (override)" | |
209 | .PD 0 | |
210 | .IP "init_others (override)" 4 | |
211 | .IX Item "init_others (override)" | |
212 | .PD | |
213 | Provide VMS-specific forms of various utility commands, then hand | |
214 | off to the default MM_Unix method. | |
215 | .Sp | |
216 | \&\s-1DEV_NULL\s0 should probably be overriden with something. | |
217 | .Sp | |
218 | Also changes \s-1EQUALIZE_TIMESTAMP\s0 to set revision date of target file to | |
219 | one second later than source file, since \s-1MMK\s0 interprets precisely | |
220 | equal revision dates for a source and target file as a sign that the | |
221 | target needs to be updated. | |
222 | .IP "init_platform (override)" 4 | |
223 | .IX Item "init_platform (override)" | |
224 | Add \s-1PERL_VMS\s0, \s-1MM_VMS_REVISION\s0 and \s-1MM_VMS_VERSION\s0. | |
225 | .Sp | |
226 | \&\s-1MM_VMS_REVISION\s0 is for backwards compatibility before \s-1MM_VMS\s0 had a | |
227 | \&\f(CW$VERSION\fR. | |
228 | .IP "platform_constants" 4 | |
229 | .IX Item "platform_constants" | |
230 | .PD 0 | |
231 | .IP "init_VERSION (override)" 4 | |
232 | .IX Item "init_VERSION (override)" | |
233 | .PD | |
234 | Override the *DEFINE_VERSION macros with \s-1VMS\s0 semantics. Translate the | |
235 | \&\s-1MAKEMAKER\s0 filepath to \s-1VMS\s0 style. | |
236 | .IP "constants (override)" 4 | |
237 | .IX Item "constants (override)" | |
238 | Fixes up numerous file and directory macros to insure \s-1VMS\s0 syntax | |
239 | regardless of input syntax. Also makes lists of files | |
240 | comma\-separated. | |
241 | .IP "special_targets" 4 | |
242 | .IX Item "special_targets" | |
243 | Clear the default .SUFFIXES and put in our own list. | |
244 | .IP "cflags (override)" 4 | |
245 | .IX Item "cflags (override)" | |
246 | Bypass shell script and produce qualifiers for \s-1CC\s0 directly (but warn | |
247 | user if a shell script for this extension exists). Fold multiple | |
248 | /Defines into one, since some C compilers pay attention to only one | |
249 | instance of this qualifier on the command line. | |
250 | .IP "const_cccmd (override)" 4 | |
251 | .IX Item "const_cccmd (override)" | |
252 | Adds directives to point C preprocessor to the right place when | |
253 | handling #include <sys/foo.h> directives. Also constructs \s-1CC\s0 | |
254 | command line a bit differently than MM_Unix method. | |
255 | .IP "tools_other (override)" 4 | |
256 | .IX Item "tools_other (override)" | |
257 | Throw in some dubious extra macros for Makefile args. | |
258 | .Sp | |
259 | Also keep around the old $(\s-1SAY\s0) macro in case somebody's using it. | |
260 | .IP "init_dist (override)" 4 | |
261 | .IX Item "init_dist (override)" | |
262 | VMSish defaults for some values. | |

290 | \& VERSION for the name | |
291 | .Ve | |
292 | .IP "c_o (override)" 4 | |
293 | .IX Item "c_o (override)" | |
294 | Use \s-1VMS\s0 syntax on command line. In particular, $(\s-1DEFINE\s0) and | |
295 | $(\s-1PERL_INC\s0) have been pulled into $(\s-1CCCMD\s0). Also use MM[\s-1SK\s0] macros. | |
296 | .IP "xs_c (override)" 4 | |
297 | .IX Item "xs_c (override)" | |
298 | Use MM[\s-1SK\s0] macros. | |
299 | .IP "xs_o (override)" 4 | |
300 | .IX Item "xs_o (override)" | |
301 | Use MM[\s-1SK\s0] macros, and \s-1VMS\s0 command line for C compiler. | |
302 | .IP "dlsyms (override)" 4 | |
303 | .IX Item "dlsyms (override)" | |
304 | Create \s-1VMS\s0 linker options files specifying universal symbols for this | |
305 | extension's shareable image, and listing other shareable images or | |
306 | libraries to which it should be linked. | |
307 | .IP "dynamic_lib (override)" 4 | |
308 | .IX Item "dynamic_lib (override)" | |
309 | Use \s-1VMS\s0 Link command. | |
310 | .IP "static_lib (override)" 4 | |
311 | .IX Item "static_lib (override)" | |
312 | Use \s-1VMS\s0 commands to manipulate object library. | |
313 | .IP "extra_clean_files" 4 | |
314 | .IX Item "extra_clean_files" | |

325 | Syntax for invoking shar, tar and zip differs from that for Unix. | |
326 | .IP "install (override)" 4 | |
327 | .IX Item "install (override)" | |
328 | Work around \s-1DCL\s0's 255 character limit several times,and use | |
329 | VMS-style command line quoting in a few cases. | |
330 | .IP "perldepend (override)" 4 | |
331 | .IX Item "perldepend (override)" | |
332 | Use VMS-style syntax for files; it's cheaper to just do it directly here | |
333 | than to have the MM_Unix method call \f(CW\*(C`catfile\*(C'\fR repeatedly. Also, if | |
334 | we have to rebuild Config.pm, use MM[\s-1SK\s0] to do it. | |
335 | .IP "makeaperl (override)" 4 | |
336 | .IX Item "makeaperl (override)" | |
337 | Undertake to build a new set of Perl images using \s-1VMS\s0 commands. Since | |
338 | \&\s-1VMS\s0 does dynamic loading, it's not necessary to statically link each | |
339 | extension into the Perl image, so this isn't the normal build path. | |
340 | Consequently, it hasn't really been tested, and may well be incomplete. | |
341 | .IP "nicetext (override)" 4 | |
342 | .IX Item "nicetext (override)" | |
343 | Insure that colons marking targets are preceded by space, in order | |
344 | to distinguish the target delimiter from a colon appearing as | |
345 | part of a filespec. | |
346 | .IP "prefixify (override)" 4 | |
347 | .IX Item "prefixify (override)" | |
348 | prefixifying on \s-1VMS\s0 is simple. Each should simply be: | |
349 | .Sp | |
350 | .Vb 1 | |
351 | \& perl_root:[some.dir] | |
352 | .Ve | |
353 | .Sp | |

356 | .Vb 1 | |
357 | \& volume:[your.prefix.some.dir] | |
358 | .Ve | |
359 | .Sp | |
360 | otherwise you get the default layout. | |
361 | .Sp | |
362 | In effect, your search prefix is ignored and \f(CW$Config\fR{vms_prefix} is | |
363 | used instead. | |

402 | Catchall routine to clean up problem MM[\s-1SK\s0]/Make macros. Expands macros | |
403 | in any directory specification, in order to avoid juxtaposing two | |
404 | VMS-syntax directories when MM[\s-1SK\s0] is run. Also expands expressions which | |
405 | are all macro, so that we can tell how long the expansion is, and avoid | |
406 | overrunning \s-1DCL\s0's command buffer when MM[\s-1KS\s0] is running. | |

408 | \&\fIfixpath()\fR checks to see whether the result matches the name of a | |
409 | directory in the current default directory and returns a directory or | |
410 | file specification accordingly. \f(CW$is_dir\fR can be set to true to | |
411 | force \fIfixpath()\fR to consider the path to be a directory or false to force | |
412 | it to be a file. | |
