336 | =head1 NAME |
337 | |
338 | buildperl.pl - build/install perl distributions |
339 | |
340 | =head1 SYNOPSIS |
341 | |
342 | perl buildperl.pl [options] |
343 | |
344 | --help show this help |
345 | |
346 | --source=directory directory containing source tarballs |
347 | [default: /tmp/perl/source] |
348 | |
349 | --build=directory directory used for building perls [EXPAND] |
350 | [default: /tmp/perl/build/<config>] |
351 | |
352 | --prefix=directory use this installation prefix [EXPAND] |
353 | [default: /tmp/perl/install/<config>/<perl>] |
354 | |
355 | --config=configuration build this configuration [MULTI] |
356 | [default: all possible configurations] |
357 | |
358 | --perl=version build this version of perl [MULTI] |
359 | [default: all possible versions] |
360 | |
361 | --force rebuild and install already installed versions |
362 | |
363 | --test run test suite after building |
364 | |
365 | --noinstall don't install after building |
366 | |
367 | options tagged with [MULTI] can be given multiple times |
368 | |
369 | options tagged with [EXPAND] expand the following items |
370 | |
371 | <perl> versioned perl directory (e.g. 'perl-5.6.1') |
372 | <version> perl version (e.g. '5.6.1') |
373 | <config> name of the configuration (e.g. 'default') |
374 | |
375 | =head1 EXAMPLES |
376 | |
377 | The following examples assume that your Perl source tarballs are |
378 | in F</tmp/perl/source>. If they are somewhere else, use the C<--source> |
379 | option to specify a different source directory. |
380 | |
381 | To build a default configuration of perl5.004_05 and install it |
382 | to F</opt/perl5.004_05>, you would say: |
383 | |
384 | buildperl.pl --prefix='/opt/<perl>' --perl=5.004_05 --config=default |
385 | |
386 | To build debugging configurations of all perls in the source directory |
387 | and install them to F</opt>, use: |
388 | |
389 | buildperl.pl --prefix='/opt/<perl>' --config=debug |
390 | |
391 | To build all configurations for perl-5.8.5 and perl-5.8.6, test them |
392 | and don't install them, run: |
393 | |
394 | buildperl.pl --perl=5.8.5 --perl=5.8.6 --test --noinstall |
