| 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. |

| 208 | .IX Item "init_main (override)" |
| 209 | .PD 0 |

| 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 |

| 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. |

| 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. |

| 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: |

| 350 | .Vb 1 |
| 351 | \& perl_root:[some.dir] |

| 359 | .Sp |

| 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. |
