300 | =item F<staticperl mkbundle> args... |
|
|
301 | |
|
|
302 | The "default" bundle command - it interprets the given bundle options and |
|
|
303 | writes out F<bundle.h>, F<bundle.c>, F<bundle.ccopts> and F<bundle.ldopts> |
|
|
304 | files, useful for embedding. |
|
|
305 | |
|
|
306 | =item F<staticperl mkperl> args... |
|
|
307 | |
|
|
308 | Creates a bundle just like F<staticperl mkbundle> (in fact, it's the same |
|
|
309 | as invoking F<staticperl mkbundle --perl> args...), but then compiles and |
|
|
310 | links a new perl interpreter that embeds the created bundle, then deletes |
|
|
311 | all intermediate files. |
|
|
312 | |
|
|
313 | =item F<staticperl mkapp> filename args... |
|
|
314 | |
|
|
315 | Does the same as F<staticperl mkbundle> (in fact, it's the same as |
|
|
316 | invoking F<staticperl mkbundle --app> filename args...), but then compiles |
|
|
317 | and links a new standalone application that simply initialises the perl |
|
|
318 | interpreter. |
|
|
319 | |
|
|
320 | The difference to F<staticperl mkperl> is that the standalone application |
|
|
321 | does not act like a perl interpreter would - in fact, by default it would |
|
|
322 | just do nothing and exit immediately, so you should specify some code to |
|

323 | be executed via the F<--boot> option. |

353 | =head3 BUNDLE CREATION WORKFLOW / STATICPERL MKBUNDLE OPTIONS |
302 | |
354 | |
303 | F<staticperl mkbundle> has a number of options to control package |
355 | F<staticperl mkbundle> works by first assembling a list of candidate |
304 | selection. This section describes how they interact with each other. Also, |
356 | files and modules to include, then filtering them by include/exclude |
305 | since I am still a newbie w.r.t. these issues, maybe future versions of |
357 | patterns. The remaining modules (together with their direct dependencies, |
306 | F<staticperl> will change this, so watch out :) |
358 | such as link libraries and L<AutoLoader> files) are then converted into |
|
|
359 | bundle files suitable for embedding. F<staticperl mkbundle> can then |
|
|
360 | optionally build a new perl interpreter or a standalone application. |
307 | |
361 | |
308 | The idiom "in order" means "in order that they are specified on the |
|
|
309 | commandline". If you use a bundle specification file, then the options |
|
|
310 | will be processed as if they were given in place of the bundle file name. |

|
|
398 | |
|
|
399 | Include the named module or perl library and trace direct |
|
|
400 | dependencies. This is done by loading the module in a subprocess and |
|
|
401 | tracing which other modules and files it actually loads. |
|
|
402 | |
|
|
403 | Example: include AnyEvent and AnyEvent::Impl::Perl. |
|
|
404 | |
|
|
405 | staticperl mkbundle --use AnyEvent --use AnyEvent::Impl::Perl |
|
|
406 | |
|
|
407 | Sometimes you want to load old-style "perl libraries" (F<.pl> files), or |
|
|
408 | maybe other weirdly named files. To support this, the C<--use> option |
|
|
409 | actually tries to do what you mean, depending on the string you specify: |
|
|
410 | |
|
|
411 | =over 4 |
|
|
412 | |
|
|
413 | =item a possibly valid module name, e.g. F<common::sense>, F<Carp>, |
|
|
414 | F<Coro::Mysql>. |
|
|
415 | |
|
|
416 | If the string contains no quotes, no F</> and no F<.>, then C<--use> |
|
|
417 | assumes that it is a normal module name. It will create a new package and |
|
|
418 | evaluate a C<use module> in it, i.e. it will load the package and do a |
|
|
419 | default import. |
|
|
420 | |
|
|
421 | The import step is done because many modules trigger more dependencies |
|
|
422 | when something is imported than without. |
|
|
423 | |
|
|
424 | =item anything that contains F</> or F<.> characters, |
|
|
425 | e.g. F<utf8_heavy.pl>, F<Module/private/data.pl>. |
|
|
426 | |
|
|
427 | The string will be quoted and passed to require, as if you used C<require |
|
|
428 | $module>. Nothing will be imported. |
|
|
429 | |
|
|
430 | =item "path" or 'path', e.g. C<"utf8_heavy.pl">. |
|
|
431 | |
|
|
432 | If you enclose the name into single or double quotes, then the quotes will |
|
|
433 | be removed and the resulting string will be passed to require. This syntax |
|
|
434 | is form compatibility with older versions of staticperl and should not be |
|
|
435 | used anymore. |
|
|
436 | |
|
|
437 | =back |
|
|
438 | |
|
|
439 | Example: C<use> AnyEvent::Socket, once using C<use> (importing the |
|
|
440 | symbols), and once via C<require>, not importing any symbols. The first |
|
|
441 | form is preferred as many modules load some extra dependencies when asked |
|
|
442 | to export symbols. |
|
|
443 | |
|
|
444 | staticperl mkbundle -MAnyEvent::Socket # use + import |
|
|
445 | staticperl mkbundle -MAnyEvent/Socket.pm # require only |
|
|
446 | |
|
|
447 | Example: include the required files for F<perl -V> to work in all its |
|
|
448 | glory (F<Config.pm> is included automatically by the dependency tracker). |
|
|
449 | |
|
|
450 | # shell command |
|
|
451 | staticperl mkbundle -MConfig_heavy.pl |
|
|
452 | |
|
|
453 | # bundle specification file |
|
|
454 | use Config_heavy.pl |
|
|
455 | |
|
|
456 | The C<-M>module syntax is included as a convenience that might be easier |
|
|
457 | to remember than C<--use> - it's the same switch as perl itself uses |
|
|
458 | to load modules. Or maybe it confuses people. Time will tell. Or maybe |
|
|
459 | not. Sigh. |
|
|
460 | |
|
|
461 | =item C<--eval> "perl code" | C<-e> "perl code" |
|
|
462 | |
|
|
463 | Sometimes it is easier (or necessary) to specify dependencies using perl |
|
|
464 | code, or maybe one of the modules you use need a special use statement. In |
|
|
465 | that case, you can use C<--eval> to execute some perl snippet or set some |
|
|
466 | variables or whatever you need. All files C<require>'d or C<use>'d while |
|
|
467 | executing the snippet are included in the final bundle. |
|
|
468 | |
|
|
469 | Keep in mind that F<mkbundle> will not import any symbols from the modules |
|
|
470 | named by the C<--use> option, so do not expect the symbols from modules |
|
|
471 | you C<--use>'d earlier on the command line to be available. |
|
|
472 | |
|
|
473 | Example: force L<AnyEvent> to detect a backend and therefore include it |
|
|
474 | in the final bundle. |
|
|
475 | |
|
|
476 | staticperl mkbundle --eval 'use AnyEvent; AnyEvent::detect' |
|
|
477 | |
|
|
478 | # or like this |
|
|
479 | staticperl mkbundle -MAnyEvent --eval 'AnyEvent::detect' |
|
|
480 | |
|
|
481 | Example: use a separate "bootstrap" script that C<use>'s lots of modules |
|
|
482 | and also include this in the final bundle, to be executed automatically |
|
|
483 | when the interpreter is initialised. |
|
|
484 | |
|
|
485 | staticperl mkbundle --eval 'do "bootstrap"' --boot bootstrap |
|
|
486 | |
|
|
487 | =item C<--boot> F<filename> |
|
|
488 | |
|
|
489 | Include the given file in the bundle and arrange for it to be |
|
|
490 | executed (using C<require>) before the main program when the new perl |
|
|
491 | is initialised. This can be used to modify C<@INC> or do similar |
|
|
492 | modifications before the perl interpreter executes scripts given on the |
|
|
493 | command line (or via C<-e>). This works even in an embedded interpreter - |
|
|
494 | the file will be executed during interpreter initialisation in that case. |
|
|
495 | |
|
|
496 | =item C<--incglob> pattern |
|
|
497 | |
|
|
498 | This goes through all standard library directories and tries to match any |
|
|
499 | F<.pm> and F<.pl> files against the extended glob pattern (see below). If |
|
|
500 | a file matches, it is added. The pattern is matched against the full path |
|
|
501 | of the file (sans the library directory prefix), e.g. F<Sys/Syslog.pm>. |
|
|
502 | |
|
|
503 | This is very useful to include "everything": |
|
|
504 | |
|
|
505 | --incglob '*' |
|
|
506 | |
|
|
507 | It is also useful for including perl libraries, or trees of those, such as |
|
|
508 | the unicode database files needed by some perl built-ins, the regex engine |
|
|
509 | and other modules. |
|
|
510 | |
|
|
511 | --incglob '/unicore/**.pl' |
|
|
512 | |
|
|
513 | =item C<--add> F<file> | C<--add> "F<file> alias" |
|
|
514 | |
|
|
515 | Adds the given (perl) file into the bundle (and optionally call it |
|
|
516 | "alias"). The F<file> is either an absolute path or a path relative to the |
|
|
517 | current directory. If an alias is specified, then this is the name it will |
|
|
518 | use for C<@INC> searches, otherwise the path F<file> will be used as the |
|
|
519 | internal name. |
|
|
520 | |
|
|
521 | This switch is used to include extra files into the bundle. |
|
|
522 | |
|
|
523 | Example: embed the file F<httpd> in the current directory as F<httpd.pm> |
|
|
524 | when creating the bundle. |
|
|
525 | |
|
|
526 | staticperl mkperl --add "httpd httpd.pm" |
|
|
527 | |
|
|
528 | # can be accessed via "use httpd" |
|
|
529 | |
|
|
530 | Example: add a file F<initcode> from the current directory. |
|
|
531 | |
|
|
532 | staticperl mkperl --add 'initcode &initcode' |
|
|
533 | |
|
|
534 | # can be accessed via "do '&initcode'" |
|
|
535 | |
|
|
536 | Example: add local files as extra modules in the bundle. |
|
|
537 | |
|
|
538 | # specification file |
|
|
539 | add file1 myfiles/file1.pm |
|
|
540 | add file2 myfiles/file2.pm |
|
|
541 | add file3 myfiles/file3.pl |
|
|
542 | |
|
|
543 | # then later, in perl, use |
|
|
544 | use myfiles::file1; |
|
|
545 | require myfiles::file2; |
|
|
546 | my $res = do "myfiles/file3.pl"; |
|
|
547 | |
|
|
548 | =item C<--addbin> F<file> | C<--addbin> "F<file> alias" |
|
|
549 | |
|
|
550 | Just like C<--add>, except that it treats the file as binary and adds it |
|
|
551 | without any post-processing (perl files might get stripped to reduce their |
|
|
552 | size). |
|
|
553 | |
|
|
554 | If you specify an alias you should probably add a C</> prefix to avoid |
|
|
555 | clashing with embedded perl files (whose paths never start with C</>), |
|
|
556 | and/or use a special directory prefix, such as C</res/name>. |
|
|
557 | |
|
|
558 | You can later get a copy of these files by calling C<static::find |
|
|
559 | "alias">. |
|
|
560 | |
|
|
561 | An alternative way to embed binary files is to convert them to perl and |
|
|
562 | use C<do> to get the contents - this method is a bit cumbersome, but works |
|
|
563 | both inside and outside of a staticperl bundle, without extra ado: |
|
|
564 | |
|
|
565 | # a "binary" file, call it "bindata.pl" |
|
|
566 | <<'SOME_MARKER' |
|
|
567 | binary data NOT containing SOME_MARKER |
|
|
568 | SOME_MARKER |
|
|
569 | |
|
|
570 | # load the binary |
|
|
571 | chomp (my $data = do "bindata.pl"); |
|
|
572 | |
|
|
573 | =item C<--allow-dynamic> |
|
|
574 | |
|
|
575 | By default, when F<mkbundle> hits a dynamic perl extension (e.g. a F<.so> |
|
|
576 | or F<.dll> file), it will stop with a fatal error. |
|
|
577 | |
|
|
578 | When this option is enabled, F<mkbundle> packages the shared |
|
|
579 | object into the bundle instead, with a prefix of F<!> |
|
|
580 | (e.g. F<!auto/List/Util/Util.so>). What you do with that is currently up |
|
|
581 | to you, F<staticperl> has no special support for this at the moment, apart |
|
|
582 | from working around the lack of availability of F<PerlIO::scalar> while |
|
|
583 | bootstrapping, at a speed cost. |
|
|
584 | |
|
|
585 | One way to deal with this is to write all files starting with F<!> into |
|
|
586 | some directory and then C<unshift> that path onto C<@INC>. |
|
|
587 | |
|
|
588 | (TODO for future self: write and insert a suitable example here, if |
|
|
589 | somebody requests it). |

593 | =item Step 2: filter all files using C<--include> and C<--exclude> options. |
|
|
594 | |
|
|
595 | After all candidate files and modules are added, they are I<filtered> |
|
|
596 | by a combination of C<--include> and C<--exclude> patterns (there is an |
|
|
597 | implicit C<--include *> at the end, so if no filters are specified, all |
|
|
598 | files are included). |
|
|
599 | |
|
|
600 | All that this step does is potentially reduce the number of files that are |
|
|
601 | to be included - no new files are added during this step. |
|
|
602 | |

604 | |
|
|
605 | =item C<--include> pattern | C<-i> pattern | C<--exclude> pattern | C<-x> pattern |
|
|
606 | |
|
|
607 | These specify an include or exclude pattern to be applied to the candidate |
|
|
608 | file list. An include makes sure that the given files will be part of the |
|
|
609 | resulting file set, an exclude will exclude remaining files. The patterns |
|
|
610 | are "extended glob patterns" (see below). |
|
|
611 | |
|
|
612 | The patterns are applied "in order" - files included via earlier |
|
|
613 | C<--include> specifications cannot be removed by any following |
|
|
614 | C<--exclude>, and likewise, and file excluded by an earlier C<--exclude> |
|
|
615 | cannot be added by any following C<--include>. |
|
|
616 | |
|
|
617 | For example, to include everything except C<Devel> modules, but still |
|
|
618 | include F<Devel::PPPort>, you could use this: |
|
|
619 | |
|
|
620 | --incglob '*' -i '/Devel/PPPort.pm' -x '/Devel/**' |

|
|
624 | =item Step 3: add any extra or "hidden" dependencies. |
|
|
625 | |
|
|
626 | F<staticperl> currently knows about three extra types of depdendencies |
|
|
627 | that are added automatically. Only one (F<.packlist> files) is currently |
|
|
628 | optional and can be influenced, the others are always included: |

632 | =item C<--usepacklists> |
|
|
633 | |
|
|
634 | Read F<.packlist> files for each distribution that happens to match a |
|
|
635 | module name you specified. Sounds weird, and it is, so expect semantics to |
|
|
636 | change somehow in the future. |
|
|
637 | |
|
|
638 | The idea is that most CPAN distributions have a F<.pm> file that matches |
|
|
639 | the name of the distribution (which is rather reasonable after all). |
|
|
640 | |
|
|
641 | If this switch is enabled, then if any of the F<.pm> files that have been |
|
|
642 | selected match an install distribution, then all F<.pm>, F<.pl>, F<.al> |
|
|
643 | and F<.ix> files installed by this distribution are also included. |
|
|
644 | |
|
|
645 | For example, using this switch, when the L<URI> module is specified, then |
|
|
646 | all L<URI> submodules that have been installed via the CPAN distribution |
|
|
647 | are included as well, so you don't have to manually specify them. |
|
|
648 | |
|
|
649 | =item L<AutoLoader> splitfiles |
|
|
650 | |
|
|
651 | Some modules use L<AutoLoader> - less commonly (hopefully) used functions |
|
|
652 | are split into separate F<.al> files, and an index (F<.ix>) file contains |
|
|
653 | the prototypes. |
|
|
654 | |
|
|
655 | Both F<.ix> and F<.al> files will be detected automatically and added to |

656 | the bundle. |

|
|
659 | |
|
|
660 | Modules using XS (or any other non-perl language extension compiled at |
|
|
661 | installation time) will have a static archive (typically F<.a>). These |
|
|
662 | will automatically be added to the linker options in F<bundle.ldopts>. |
|
|
663 | |
|
|
664 | Should F<staticperl> find a dynamic link library (typically F<.so>) it |
|
|
665 | will warn about it - obviously this shouldn't happen unless you use |
|
|
666 | F<staticperl> on the wrong perl, or one (probably wrongly) configured to |
|
|
667 | use dynamic loading. |

668 | |
|
|
669 | =item extra libraries (F<extralibs.ld>) |

760 | that might alter execution in ways that might be undesirable for |
411 | splitfiles will be included as well. |
761 | standalone applications, and this option removes those known to cause |
|
|
762 | trouble. |
412 | |
763 | |
413 | Example: include AnyEvent and AnyEvent::Impl::Perl. |
764 | Specifically, these are removed: |
414 | |
765 | |
415 | staticperl mkbundle --use AnyEvent --use AnyEvent::Impl::Perl |
766 | C<PERL_HASH_SEED_DEBUG> and C<PERL_DEBUG_MSTATS> can cause undesirable |
|
|
767 | output, C<PERL5OPT>, C<PERL_DESTRUCT_LEVEL>, C<PERL_HASH_SEED> and |
|
|
768 | C<PERL_SIGNALS> can alter execution significantly, and C<PERL_UNICODE>, |
|
|
769 | C<PERLIO_DEBUG> and C<PERLIO> can affect input and output. |
416 | |
770 | |
417 | Sometimes you want to load old-style "perl libraries" (F<.pl> files), or |
771 | The variables C<PERL_LIB> and C<PERL5_LIB> are always ignored because the |
418 | maybe other weirdly named files. To do that, you need to quote the name in |
772 | startup code used by F<staticperl> overrides C<@INC> in all cases. |
419 | single or double quotes. When given on the command line, you probably need |
|
|
420 | to quote once more to avoid your shell interpreting it. Common cases that |
|
|
421 | need this are F<Config_heavy.pl> and F<utf8_heavy.pl>. |
|
|
422 | |
773 | |
423 | Example: include the required files for F<perl -V> to work in all its |
774 | This option will not make your program more secure (unless you are |
424 | glory (F<Config.pm> is included automatically by this). |
775 | running with elevated privileges), but it will reduce the surprise effect |
|
|
776 | when a user has these environment variables set and doesn't expect your |
|
|
777 | standalone program to act like a perl interpreter. |
425 | |
778 | |
426 | # bourne shell |
|
|
427 | staticperl mkbundle --use '"Config_heavy.pl"' |
|
|
428 | |
|
|
429 | # bundle specification file |
|
|
430 | use "Config_heavy.pl" |
|
|
431 | |
|
|
432 | The C<-Mmodule> syntax is included as an alias that might be easier to |
|
|
433 | remember than C<use>. Or maybe it confuses people. Time will tell. Or |
|
|
434 | maybe not. Argh. |
|
|
435 | |
|
|
436 | =item --eval "perl code" | -e "perl code" |
|
|
437 | |
|
|
438 | Sometimes it is easier (or necessary) to specify dependencies using perl |
|
|
439 | code, or maybe one of the modules you use need a special use statement. In |
|
|
440 | that case, you can use C<eval> to execute some perl snippet or set some |
|
|
441 | variables or whatever you need. All files C<require>'d or C<use>'d in the |
|
|
442 | script are included in the final bundle. |
|
|
443 | |
|
|
444 | Keep in mind that F<mkbundle> will only C<require> the modules named |
|
|
445 | by the C<--use> option, so do not expect the symbols from modules you |
|
|
446 | C<--use>'d earlier on the command line to be available. |
|
|
447 | |
|
|
448 | Example: force L<AnyEvent> to detect a backend and therefore include it |
|
|
449 | in the final bundle. |
|
|
450 | |
|
|
451 | staticperl mkbundle --eval 'use AnyEvent; AnyEvent::detect' |
|
|
452 | |
|
|
453 | # or like this |
|
|
454 | staticperl mkbundle -MAnyEvent --eval 'use AnyEvent; AnyEvent::detect' |
|
|
455 | |
|
|
456 | Example: use a separate "bootstrap" script that C<use>'s lots of modules |
|
|
457 | and include this in the final bundle, to be executed automatically. |
|
|
458 | |
|
|
459 | staticperl mkbundle --eval 'do "bootstrap"' --boot bootstrap |
|
|
460 | |
|
|
461 | =item --boot filename |
|
|
462 | |
|
|
463 | Include the given file in the bundle and arrange for it to be executed |
|
|
464 | (using a C<require>) before anything else when the new perl is |
|
|
465 | initialised. This can be used to modify C<@INC> or anything else before |
|
|
466 | the perl interpreter executes scripts given on the command line (or via |
|
|
467 | C<-e>). This works even in an embedded interpreter. |
|
|
468 | |
|
|
469 | =item --usepacklist |
|
|
470 | |
|
|
471 | Read F<.packlist> files for each distribution that happens to match a |
|
|
472 | module name you specified. Sounds weird, and it is, so expect semantics to |
|
|
473 | change somehow in the future. |
|
|
474 | |
|
|
475 | The idea is that most CPAN distributions have a F<.pm> file that matches |
|
|
476 | the name of the distribution (which is rather reasonable after all). |
|
|
477 | |
|
|
478 | If this switch is enabled, then if any of the F<.pm> files that have been |
|
|
479 | selected match an install distribution, then all F<.pm>, F<.pl>, F<.al> |
|
|
480 | and F<.ix> files installed by this distribution are also included. |
|
|
481 | |
|
|
482 | For example, using this switch, when the L<URI> module is specified, then |
|
|
483 | all L<URI> submodules that have been installed via the CPAN distribution |
|
|
484 | are included as well, so you don't have to manually specify them. |
|
|
485 | |
|
|
486 | =item --incglob pattern |
|
|
487 | |
|
|
488 | This goes through all library directories and tries to match any F<.pm> |
|
|
489 | and F<.pl> files against the extended glob pattern (see below). If a file |
|
|
490 | matches, it is added. This switch will automatically detect L<AutoLoader> |
|
|
491 | files and the required link libraries for XS modules, but it will I<not> |
|
|
492 | scan the file for dependencies (at the moment). |
|
|
493 | |
|
|
494 | This is mainly useful to include "everything": |
|
|
495 | |
|
|
496 | --incglob '*' |
|
|
497 | |
|
|
498 | Or to include perl libraries, or trees of those, such as the unicode |
|
|
499 | database files needed by many other modules: |
|
|
500 | |
|
|
501 | --incglob '/unicore/**.pl' |
|
|
502 | |
|
|
503 | =item --add file | --add "file alias" |
|
|
504 | |
|
|
505 | Adds the given (perl) file into the bundle (and optionally call it |
|
|
506 | "alias"). This is useful to include any custom files into the bundle. |
|
|
507 | |
|
|
508 | Example: embed the file F<httpd> as F<httpd.pm> when creating the bundle. |
|
|
509 | |
|
|
510 | staticperl mkperl --add "httpd httpd.pm" |
|
|
511 | |
|
|
512 | It is also a great way to add any custom modules: |
|
|
513 | |
|
|
514 | # specification file |
|
|
515 | add file1 myfiles/file1 |
|
|
516 | add file2 myfiles/file2 |
|
|
517 | add file3 myfiles/file3 |
|
|
518 | |
|
|
519 | =item --binadd file | --add "file alias" |
|
|
520 | |
|
|
521 | Just like C<--add>, except that it treats the file as binary and adds it |
|
|
522 | without any processing. |
|
|
523 | |
|
|
524 | You should probably add a C</> prefix to avoid clashing with embedded |
|
|
525 | perl files (whose paths do not start with C</>), and/or use a special |
|
|
526 | directory, such as C</res/name>. |
|
|
527 | |
|
|
528 | You can later get a copy of these files by calling C<staticperl::find |
|
|
529 | "alias">. |
|
|
530 | |
|
|
531 | =item --include pattern | -i pattern | --exclude pattern | -x pattern |
|
|
532 | |
|
|
533 | These two options define an include/exclude filter that is used after all |
|
|
534 | files selected by the other options have been found. Each include/exclude |
|
|
535 | is applied to all files found so far - an include makes sure that the |
|
|
536 | given files will be part of the resulting file set, an exclude will |
|
|
537 | exclude files. The patterns are "extended glob patterns" (see below). |
|
|
538 | |
|
|
539 | For example, to include everything, except C<Devel> modules, but still |
|
|
540 | include F<Devel::PPPort>, you could use this: |
|
|
541 | |
|
|
542 | --incglob '*' -i '/Devel/PPPort.pm' -x '/Devel/**' |
|
|
543 | |
|
|
544 | =item --static |
779 | =item C<--static> |
545 | |

546 | When C<--perl> is also given, link statically instead of dynamically. The |
781 | Add C<-static> to F<bundle.ldopts>, which means a fully static (if |
|
|
782 | supported by the OS) executable will be created. This is not immensely |
|
|
783 | useful when just creating the bundle files, but is most useful when |
|
|
784 | linking a binary with the C<--perl> or C<--app> options. |

785 | |

895 | =head1 FULLY STATIC BINARIES - BUILDROOT |
1276 | =head1 FULLY STATIC BINARIES - ALPINE LINUX |
896 | |
1277 | |
897 | To make truly static (Linux-) libraries, you might want to have a look at |
1278 | This section once contained a way to build fully static (including |
898 | buildroot (L<http://buildroot.uclibc.org/>). |
1279 | uClibc) binaries with buildroot. Unfortunately, buildroot no longer |
|
|
1280 | supports a compiler, so I recommend using alpine linux instead |
|
|
1281 | (L<http://alpinelinux.org/>). Get yourself a VM (e.g. with qemu), run an |
|
|
1282 | older alpine linux verison in it (e.g. 2.4), copy staticperl inside and |
|
|
1283 | use it. |
899 | |
1284 | |
900 | Buildroot is primarily meant to set up a cross-compile environment (which |
1285 | The reason you might want an older alpine linux is that uClibc can be |
901 | is not so useful as perl doesn't quite like cross compiles), but it can also compile |
1286 | quite dependent on kernel versions, so the newest version of alpine linux |
902 | a chroot environment where you can use F<staticperl>. |
1287 | might need a newer kernel then you might want for, if you plan to run your |
903 | |
1288 | binaries on on other kernels. |
904 | To do so, download buildroot, and enable "Build options => development |
|
|
905 | files in target filesystem" and optionally "Build options => gcc |
|
|
906 | optimization level (optimize for size)". At the time of writing, I had |
|
|
907 | good experiences with GCC 4.4.x but not GCC 4.5. |
|
|
908 | |
|
|
909 | To minimise code size, I used C<-pipe -ffunction-sections -fdata-sections |
|
|
910 | -finline-limit=8 -fno-builtin-strlen -mtune=i386>. The C<-mtune=i386> |
|
|
911 | doesn't decrease codesize much, but it makes the file much more |
|
|
912 | compressible. |
|
|
913 | |
|
|
914 | If you don't need Coro or threads, you can go with "linuxthreads.old" (or |
|
|
915 | no thread support). For Coro, it is highly recommended to switch to a |
|
|
916 | uClibc newer than 0.9.31 (at the time of this writing, I used the 20101201 |
|
|
917 | snapshot) and enable NPTL, otherwise Coro needs to be configured with the |
|
|
918 | ultra-slow pthreads backend to work around linuxthreads bugs (it also uses |
|
|
919 | twice the address space needed for stacks). |
|
|
920 | |
|
|
921 | If you use C<linuxthreads.old>, then you should also be aware that |
|
|
922 | uClibc shares C<errno> between all threads when statically linking. See |
|
|
923 | L<http://lists.uclibc.org/pipermail/uclibc/2010-June/044157.html> for a |
|
|
924 | workaround (And L<https://bugs.uclibc.org/2089> for discussion). |
|
|
925 | |
|
|
926 | C<ccache> support is also recommended, especially if you want |
|
|
927 | to play around with buildroot options. Enabling the C<miniperl> |
|
|
928 | package will probably enable all options required for a successful |
|
|
929 | perl build. F<staticperl> itself additionally needs either C<wget> |
|
|
930 | (recommended, for CPAN) or C<curl>. |
|
|
931 | |
|
|
932 | As for shells, busybox should provide all that is needed, but the default |
|
|
933 | busybox configuration doesn't include F<comm> which is needed by perl - |
|
|
934 | either make a custom busybox config, or compile coreutils. |
|
|
935 | |
|
|
936 | For the latter route, you might find that bash has some bugs that keep |

|
|
1351 | |
|
|
1352 | Glib literally requires Glib to be installed already to build - it tries |
|
|
1353 | to fake this by running Glib out of the build directory before being |
|
|
1354 | built. F<staticperl> tries to work around this by forcing C<MAN1PODS> and |
|
|
1355 | C<MAN3PODS> to be empty via the C<PERL_MM_OPT> environment variable. |

1361 | =item Net::SSLeay |
|
|
1362 | |
|
|
1363 | This module hasn't been significantly updated since OpenSSL is called |
|
|
1364 | OpenSSL, and fails to properly link against dependent libraries, most |
|
|
1365 | commonly, it forgets to specify C<-ldl> when linking. |
|
|
1366 | |
|
|
1367 | On GNU/Linux systems this usually goes undetected, as perl usually links |
|
|
1368 | against C<-ldl> itself and OpenSSL just happens to pick it up that way, by |
|
|
1369 | chance. |
|
|
1370 | |
|
|
1371 | For static builds, you either have to configure C<-ldl> manually, or you |
|
|
1372 | can use the following snippet in your C<postinstall> hook which patches |
|
|
1373 | Net::SSLeay after installation, which happens to work most of the time: |
|
|
1374 | |
|
|
1375 | postinstall() { |
|
|
1376 | # first install it |
|
|
1377 | instcpan Net::SSLeay |
|
|
1378 | # then add -ldl for future linking |
|
|
1379 | chmod u+w "$PERL_PREFIX"/lib/auto/Net/SSLeay/extralibs.ld |
