SYNOPSIS

12        my $build = Alien::Build->load('./alienfile');
13        $build->load_requires('configure');
14        $build->set_prefix('/usr/local');
15        $build->set_stage('/foo/mystage');  # needs to be absolute

18        $build->build;
19        # files are now in /foo/mystage, it is your job (or
20        # ExtUtils::MakeMaker, Module::Build, etc) to copy
21        # those files into /usr/local
22

DESCRIPTION

24       This module provides tools for building external (non-CPAN)
25       dependencies for CPAN.  It is mainly designed to be used at install
26       time of a CPAN client, and work closely with Alien::Base which is used
27       at runtime.
28
29       This is the detailed documentation for the Alien::Build class.  If you
30       are starting out you probably want to do so from one of these
31       documents:
32
33       Alien::Build::Manual::Alien
34           A broad overview of "Alien-Build" and its ecosystem.
35
36       Alien::Build::Manual::AlienUser
37           For users of an "Alien::libfoo" that is implemented using
38           Alien::Base.  (The developer of "Alien::libfoo" should provide the
39           documentation necessary, but if not, this is the place to start).
40
41       Alien::Build::Manual::AlienAuthor
42           If you are writing your own Alien based on Alien::Build and
43           Alien::Base.
44
45       Alien::Build::Manual::FAQ
46           If you have a common question that has already been answered, like
47           "How do I use alienfile with some build system".
48
49       Alien::Build::Manual::PluginAuthor
50           This is for the brave souls who want to write plugins that will
51           work with Alien::Build + alienfile.
52
53       Note that you will not usually create a Alien::Build instance directly,
54       but rather be using a thin installer layer, such as Alien::Build::MM
55       (for use with ExtUtils::MakeMaker) or Alien::Build::MB (for use with
56       Module::Build).  One of the goals of this project is to remain
57       installer agnostic.
58

CONSTRUCTORS

60   new
61        my $build = Alien::Build->new;
62
63       This creates a new empty instance of Alien::Build.  Normally you will
64       want to use "load" below to create an instance of Alien::Build from an
65       alienfile recipe.
66
67   load
68        my $build = Alien::Build->load($alienfile);
69
70       This creates an Alien::Build instance with the given alienfile recipe.
71
72   resume
73        my $build = Alien::Build->resume($alienfile, $root);
74
75       Load a checkpointed Alien::Build instance.  You will need the original
76       alienfile and the build root (usually "_alien"), and a build that had
77       been properly checkpointed using the "checkpoint" method below.
78

PROPERTIES

80       There are three main properties for Alien::Build.  There are a number
81       of properties documented here with a specific usage.  Note that these
82       properties may need to be serialized into something primitive like JSON
83       that does not support: regular expressions, code references of blessed
84       objects.
85
86       If you are writing a plugin (Alien::Build::Plugin) you should use a
87       prefix like "plugin_name" (where name is the name of your plugin) so
88       that it does not interfere with other plugin or future versions of
89       Alien::Build.  For example, if you were writing
90       "Alien::Build::Plugin::Fetch::NewProtocol", please use the prefix
91       "plugin_fetch_newprotocol":
92
93        sub init
94        {
95          my($self, $meta) = @_;
96
97          $meta->prop( plugin_fetch_newprotocol_foo => 'some value' );
98
99          $meta->register_hook(
100            some_hook => sub {
101              my($build) = @_;
102              $build->install_prop->{plugin_fetch_newprotocol_bar} = 'some other value';
103              $build->runtime_prop->{plugin_fetch_newprotocol_baz} = 'and another value';
104            }
105          );
106        }
107
108       If you are writing a alienfile recipe please use the prefix "my_":
109
110        use alienfile;
111
112        meta_prop->{my_foo} = 'some value';
113
114        probe sub {
115          my($build) = @_;
116          $build->install_prop->{my_bar} = 'some other value';
117          $build->install_prop->{my_baz} = 'and another value';
118        };
119
120       Any property may be used from a command:
121
122        probe [ 'some command %{.meta.plugin_fetch_newprotocol_foo}' ];
123        probe [ 'some command %{.install.plugin_fetch_newprotocol_bar}' ];
124        probe [ 'some command %{.runtime.plugin_fetch_newprotocol_baz}' ];
125        probe [ 'some command %{.meta.my_foo}' ];
126        probe [ 'some command %{.install.my_bar}' ];
127        probe [ 'some command %{.runtime.my_baz}' ];
128
129   meta_prop
130        my $href = $build->meta_prop;
131        my $href = Alien::Build->meta_prop;
132
133       Meta properties have to do with the recipe itself, and not any
134       particular instance that probes or builds that recipe.  Meta properties
135       can be changed from within an alienfile using the "meta_prop"
136       directive, or from a plugin from its "init" method (though should NOT
137       be modified from any hooks registered within that "init" method).  This
138       is not strictly enforced, but if you do not follow this rule your
139       recipe will likely be broken.
140
141       arch
142           This is a hint to an installer like Alien::Build::MM or
143           Alien::Build::MB, that the library or tool contains architecture
144           dependent files and so should be stored in an architecture
145           dependent location.  If not specified by your alienfile then it
146           will be set to true.
147
148       destdir
149           Use the "DESTDIR" environment variable to stage your install before
150           copying the files into "blib".  This is the preferred method of
151           installing libraries because it improves reliability.  This
152           technique is supported by "autoconf" and others.
153
154       destdir_filter
155           Regular expression for the files that should be copied from the
156           "DESTDIR" into the stage directory.  If not defined, then all files
157           will be copied.
158
159       destdir_ffi_filter
160           Same as "destdir_filter" except applies to "build_ffi" instead of
161           "build".
162
163       env Environment variables to override during the build stage.
164
165       env_interpolate
166           Environment variable values will be interpolated with helpers.
167           Example:
168
169            meta->prop->{env_interpolate} = 1;
170            meta->prop->{env}->{PERL} = '%{perl}';
171
172       local_source
173           Set to true if source code package is available locally.  (that is
174           not fetched over the internet).  This is computed by default based
175           on the "start_url" property.  Can be set by an alienfile or plugin.
176
177       platform
178           Hash reference.  Contains information about the platform beyond
179           just $^O.
180
181           compiler_type
182               Refers to the type of flags that the compiler accepts.  May be
183               expanded in the future, but for now, will be one of:
184
185               microsoft
186                   On Windows when using Microsoft Visual C++
187
188               unix
189                   Virtually everything else, including gcc on windows.
190
191               The main difference is that with Visual C++ "-LIBPATH" should
192               be used instead of "-L", and static libraries should have the
193               ".LIB" suffix instead of ".a".
194
195           system_type
196               $^O is frequently good enough to make platform specific logic
197               in your alienfile, this handles the case when $^O can cover
198               platforms that provide multiple environments that Perl might
199               run under.  The main example is windows, but others may be
200               added in the future.
201
202               unix
203               vms
204               windows-activestate
205               windows-microsoft
206               windows-mingw
207               windows-strawberry
208               windows-unknown
209
210               Note that "cygwin" and "msys" are considered "unix" even though
211               they run on windows!
212
213       out_of_source
214           Build in a different directory from the where the source code is
215           stored.  In autoconf this is referred to as a "VPATH" build.
216           Everyone else calls this an "out-of-source" build.  When this
217           property is true, instead of extracting to the source build root,
218           the downloaded source will be extracted to an source extraction
219           directory and the source build root will be empty.  You can use the
220           "extract" install property to get the location of the extracted
221           source.
222
223       network
224           True if a network fetch is available.  This should NOT be set by an
225           alienfile or plugin.  This is computed based on the
226           "ALIEN_INSTALL_NETWORK" environment variables.
227
228       start_url
229           The default or start URL used by fetch plugins.
230
231   install_prop
232        my $href = $build->install_prop;
233
234       Install properties are used during the install phase (either under
235       "share" or "system" install).  They are remembered for the entire
236       install phase, but not kept around during the runtime phase.  Thus they
237       cannot be accessed from your Alien::Base based module.
238
239       autoconf_prefix
240           The prefix as understood by autoconf.  This is only different on
241           Windows Where MSYS is used and paths like "C:/foo" are  represented
242           as "/C/foo" which are understood by the MSYS tools, but not by
243           Perl.  You should only use this if you are using
244           Alien::Build::Plugin::Autoconf in your alienfile.
245
246       download
247           The location of the downloaded archive (tar.gz, or similar) or
248           directory.
249
250       env Environment variables to override during the build stage.
251
252       extract
253           The location of the last source extraction.  For a "out-of-source"
254           build (see the "out_of_source" meta property above), this will only
255           be set once.  For other types of builds, the source code may be
256           extracted multiple times, and thus this property may change.
257
258       old Hash containing information on a previously installed Alien of the
259           same name, if available.  This may be useful in cases where you
260           want to reuse the previous install if it is still sufficient.
261
262           prefix
263               The prefix for the previous install.  Versions prior to 1.42
264               unfortunately had this in typo form of "preifx".
265
266           runtime
267               The runtime properties from the previous install.
268
269       patch
270           Directory with patches.
271
272       prefix
273           The install time prefix.  Under a "destdir" install this is the
274           same as the runtime or final install location.  Under a
275           non-"destdir" install this is the "stage" directory (usually the
276           appropriate share directory under "blib").
277
278       root
279           The build root directory.  This will be an absolute path.  It is
280           the absolute form of "./_alien" by default.
281
282       stage
283           The stage directory where files will be copied.  This is usually
284           the root of the blib share directory.
285
286   runtime_prop
287        my $href = $build->runtime_prop;
288
289       Runtime properties are used during the install and runtime phases
290       (either under "share" or "system" install).  This should include
291       anything that you will need to know to use the library or tool during
292       runtime, and shouldn't include anything that is no longer relevant once
293       the install process is complete.
294
295       alien_build_version
296           The version of Alien::Build used to install the library or tool.
297
298       alt Alternate configurations.  If the alienized package has multiple
299           libraries this could be used to store the different compiler or
300           linker flags for each library.
301
302       cflags
303           The compiler flags
304
305       cflags_static
306           The static compiler flags
307
308       command
309           The command name for tools where the name my differ from platform
310           to platform.  For example, the GNU version of make is usually
311           "make" in Linux and "gmake" on FreeBSD.
312
313       ffi_name
314           The name DLL or shared object "name" to use when searching for
315           dynamic libraries at runtime.  This is passed into FFI::CheckLib,
316           so if your library is something like "libarchive.so" or
317           "archive.dll" you would set this to "archive".  This may be a
318           string or an array of strings.
319
320       ffi_checklib
321           This property contains two sub properties:
322
323           share
324                $build->runtime_prop->{ffi_checklib}->{share} = [ ... ];
325
326               Array of additional FFI::CheckLib flags to pass in to
327               "find_lib" for a "share" install.
328
329           system
330               Array of additional FFI::CheckLib flags to pass in to
331               "find_lib" for a "system" install.
332
333               Among other things, useful for specifying the
334               "try_linker_script" flag:
335
336                $build->runtime_prop->{ffi_checklib}->{system} = [ try_linker_script => 1 ];
337
338       install_type
339           The install type.  Is one of:
340
341           system
342               For when the library or tool is provided by the operating
343               system, can be detected by Alien::Build, and is considered
344               satisfactory by the "alienfile" recipe.
345
346           share
347               For when a system install is not possible, the library source
348               will be downloaded from the internet or retrieved in another
349               appropriate fashion and built.
350
351       libs
352           The library flags
353
354       libs_static
355           The static library flags
356
357       perl_module_version
358           The version of the Perl module used to install the alien (if
359           available).  For example if Alien::curl is installing "libcurl"
360           this would be the version of Alien::curl used during the install
361           step.
362
363       prefix
364           The final install root.  This is usually they share directory.
365
366       version
367           The version of the library or tool
368
369   hook_prop
370        my $href = $build->hook_prop;
371
372       Hook properties are for the currently running (if any) hook.  They are
373       used only during the execution of each hook and are discarded after.
374       If no hook is currently running then "hook_prop" will return "undef".
375
376       name
377           The name of the currently running hook.
378
379       version (probe)
380           Probe and PkgConfig plugins may set this property indicating the
381           version of the alienized package.  Not all plugins and
382           configurations may be able to provide this.
383

METHODS

385   checkpoint
386        $build->checkpoint;
387
388       Save any install or runtime properties so that they can be reloaded on
389       a subsequent run in a separate process.  This is useful if your build
390       needs to be done in multiple stages from a "Makefile", such as with
391       ExtUtils::MakeMaker.  Once checkpointed you can use the "resume"
392       constructor (documented above) to resume the probe/build/install]
393       process.
394
395   root
396        my $dir = $build->root;
397
398       This is just a shortcut for:
399
400        my $root = $build->install_prop->{root};
401
402       Except that it will be created if it does not already exist.
403
404   install_type
405        my $type = $build->install_type;
406
407       This will return the install type.  (See the like named install
408       property above for details).  This method will call "probe" if it has
409       not already been called.
410
411   set_prefix
412        $build->set_prefix($prefix);
413
414       Set the final (unstaged) prefix.  This is normally only called by
415       Alien::Build::MM and similar modules.  It is not intended for use from
416       plugins or from an alienfile.
417
418   set_stage
419        $build->set_stage($dir);
420
421       Sets the stage directory.  This is normally only called by
422       Alien::Build::MM and similar modules.  It is not intended for use from
423       plugins or from an alienfile.
424
425   requires
426        my $hash = $build->requires($phase);
427
428       Returns a hash reference of the modules required for the given phase.
429       Phases include:
430
431       configure
432           These modules must already be available when the alienfile is read.
433
434       any These modules are used during either a "system" or "share" install.
435
436       share
437           These modules are used during the build phase of a "share" install.
438
439       system
440           These modules are used during the build phase of a "system"
441           install.
442
443   load_requires
444        $build->load_requires($phase);
445
446       This loads the appropriate modules for the given phase (see "requires"
447       above for a description of the phases).
448
449   probe
450        my $install_type = $build->probe;
451
452       Attempts to determine if the operating system has the library or tool
453       already installed.  If so, then the string "system" will be returned
454       and a system install will be performed.  If not, then the string
455       "share" will be installed and the tool or library will be downloaded
456       and built from source.
457
458       If the environment variable "ALIEN_INSTALL_TYPE" is set, then that will
459       force a specific type of install.  If the detection logic cannot
460       accommodate the install type requested then it will fail with an
461       exception.
462
463   download
464        $build->download;
465
466       Download the source, usually as a tarball, usually from the internet.
467
468       Under a "system" install this does not do anything.
469
470   fetch
471        my $res = $build->fetch;
472        my $res = $build->fetch($url);
473
474       Fetch a resource using the fetch hook.  Returns the same hash structure
475       described below in the hook documentation.
476
477   decode
478        my $decoded_res = $build->decode($res);
479
480       Decode the HTML or file listing returned by "fetch".  Returns the same
481       hash structure described below in the hook documentation.
482
483   prefer
484        my $sorted_res = $build->prefer($res);
485
486       Filter and sort candidates.  The preferred candidate will be returned
487       first in the list.  The worst candidate will be returned last.  Returns
488       the same hash structure described below in the hook documentation.
489
490   extract
491        my $dir = $build->extract;
492        my $dir = $build->extract($archive);
493
494       Extracts the given archive into a fresh directory.  This is normally
495       called internally to Alien::Build, and for normal usage is not needed
496       from a plugin or alienfile.
497
498   build
499        $build->build;
500
501       Run the build step.  It is expected that "probe" and "download" have
502       already been performed.  What it actually does depends on the type of
503       install:
504
505       share
506           The source is extracted, and built as determined by the alienfile
507           recipe.  If there is a "gather_share" that will be executed last.
508
509       system
510           The "gather_system" hook will be executed.
511
512   test
513        $build->test;
514
515       Run the test phase
516
517   clean_install
518        $build->clean_install
519
520       Clean files from the final install location.  The default
521       implementation removes all files recursively except for the "_alien"
522       directory.  This is helpful when you have an old install with files
523       that may break the new build.
524
525       For a non-share install this doesn't do anything.
526
527   system
528        $build->system($command);
529        $build->system($command, @args);
530
531       Interpolates the command and arguments and run the results using the
532       Perl "system" command.
533
534   log
535        $build->log($message);
536
537       Send a message to the log.  By default this prints to "STDOUT".
538
539   meta
540        my $meta = Alien::Build->meta;
541        my $meta = $build->meta;
542
543       Returns the meta object for your Alien::Build class or instance.  The
544       meta object is a way to manipulate the recipe, and so any changes to
545       the meta object should be made before the "probe", "download" or
546       "build" steps.
547

META METHODS

549   prop
550        my $href = $build->meta->prop;
551
552       Meta properties.  This is the same as calling "meta_prop" on the class
553       or Alien::Build instance.
554
555   add_requires
556        Alien::Build->meta->add_requires($phase, $module => $version, ...);
557
558       Add the requirement to the given phase.  Phase should be one of:
559
560       configure
561       any
562       share
563       system
564
565   interpolator
566        my $interpolator = $build->meta->interpolator;
567        my $interpolator = Alien::Build->interpolator;
568
569       Returns the Alien::Build::Interpolate instance for the Alien::Build
570       class.
571
572   has_hook
573        my $bool = $build->meta->has_hook($name);
574        my $bool = Alien::Build->has_hook($name);
575
576       Returns if there is a usable hook registered with the given name.
577
578   register_hook
579        $build->meta->register_hook($name, $instructions);
580        Alien::Build->meta->register_hook($name, $instructions);
581
582       Register a hook with the given name.  $instruction should be either a
583       code reference, or a command sequence, which is an array reference.
584
585   default_hook
586        $build->meta->default_hook($name, $instructions);
587        Alien::Build->meta->default_hook($name, $instructions);
588
589       Register a default hook, which will be used if the alienfile does not
590       register its own hook with that name.
591
592   around_hook
593        $build->meta->around_hook($hook, $code);
594        Alien::Build->meta->around_hook($name, $code);
595
596       Wrap the given hook with a code reference.  This is similar to a Moose
597       method modifier, except that it wraps around the given hook instead of
598       a method.  For example, this will add a probe system requirement:
599
600        $build->meta->around_hook(
601          probe => sub {
602            my $orig = shift;
603            my $build = shift;
604            my $type = $orig->($build, @_);
605            return $type unless $type eq 'system';
606            # also require a configuration file
607            if(-f '/etc/foo.conf')
608            {
609              return 'system';
610            }
611            else
612            {
613              return 'share';
614            }
615          },
616        );
617
618   apply_plugin
619        Alien::Build->meta->apply_plugin($name);
620        Alien::Build->meta->apply_plugin($name, @args);
621
622       Apply the given plugin with the given arguments.
623

ENVIRONMENT

625       Alien::Build responds to these environment variables:
626
627       ALIEN_INSTALL_NETWORK
628           If set to true (the default), then network fetch will be allowed.
629           If set to false, then network fetch will not be allowed.
630
631           What constitutes a local vs. network fetch is determined based on
632           the "start_url" and "local_source" meta properties.  An alienfile
633           or plugin "could" override this detection (possibly
634           inappropriately), so this variable is not a substitute for properly
635           auditing of Perl modules for environments that require that.
636
637       ALIEN_INSTALL_TYPE
638           If set to "share" or "system", it will override the system
639           detection logic.  If set to "default", it will use the default
640           setting for the alienfile.  The behavior of other values is
641           undefined.
642
643           Although the recommended way for a consumer to use an Alien::Base
644           based Alien is to declare it as a static configure and build-time
645           dependency, some consumers may prefer to fallback on using an Alien
646           only when the consumer itself cannot detect the necessary package.
647           In some cases the consumer may want the user to opt-in to using an
648           Alien before requiring it.
649
650           To keep the interface consistent among Aliens, the consumer of the
651           fallback opt-in Alien may fallback on the Alien if the environment
652           variable "ALIEN_INSTALL_TYPE" is set to any value. The rationale is
653           that by setting this environment variable the user is aware that
654           Alien modules may be installed and have indicated consent.  The
655           actual implementation of this, by its nature would have to be in
656           the consuming CPAN module.
657
658       ALIEN_BUILD_LOG
659           The default log class used.  See Alien::Build::Log and
660           <Alien:Build::Log::Default>.
661
662       ALIEN_BUILD_RC
663           Perl source file which can override some global defaults for
664           Alien::Build, by, for example, setting preload and postload
665           plugins.
666
667       ALIEN_BUILD_PKG_CONFIG
668           Override the logic in Alien::Build::Plugin::PkgConfig::Negotiate
669           which chooses the best "pkg-config" plugin.
670
671       ALIEN_BUILD_PRELOAD
672           semicolon separated list of plugins to automatically load before
673           parsing your alienfile.
674
675       ALIEN_BUILD_POSTLOAD
676           semicolon separated list of plugins to automatically load after
677           parsing your alienfile.
678
679       DESTDIR
680           This environment variable will be manipulated during a destdir
681           install.
682
683       PKG_CONFIG
684           This environment variable can be used to override the program name
685           for "pkg-config" when using the command line plugin:
686           Alien::Build::Plugin::PkgConfig::CommandLine.
687
688       ftp_proxy, all_proxy
689           If these environment variables are set, it may influence the
690           Download negotiation plugin
691           Alien::Build::Plugin::Downaload::Negotiate.  Other proxy variables
692           may be used by some Fetch plugins, if they support it.
693

SUPPORT

695       The intent of the "Alien-Build" team is to support as best as possible
696       all Perls from 5.8.1 to the latest production version.  So long as they
697       are also supported by the Perl toolchain.
698
699       Please feel encouraged to report issues that you encounter to the
700       project GitHub Issue tracker:

THANKS

724       Alien::Base was originally written by Joel Berger, the rest of this
725       project would not have been possible without him getting the project
726       started.  Thanks to his support I have been able to augment the
727       original Alien::Base system with a reliable set of tools (Alien::Build,
728       alienfile, Test::Alien), which make up this toolset.
729
730       The original Alien::Base is still copyright (c) 2012-2017 Joel Berger.
731       It has the same license as the rest of the Alien::Build and related
732       tools distributed as "Alien-Build".  Joel Berger thanked a number of
733       people who helped in in the development of Alien::Base, in the
734       documentation for that module.
735
736       I would also like to acknowledge the other members of the Perl5-Alien
737       github organization, Zakariyya Mughal (sivoais, ZMUGHAL) and mohawk
738       (ETJ).  Also important in the early development of Alien::Build were
739       the early adopters Chase Whitener (genio, CAPOEIRAB, author of
740       Alien::libuv), William N. Braswell, Jr (willthechill, WBRASWELL, author
741       of Alien::JPCRE2 and Alien::PCRE2) and Ahmad Fatoum (a3f, ATHREEF,
742       author of Alien::libudev and Alien::LibUSB).
