6 Alien::Base::ModuleBuild - A Module::Build subclass for building
7 Alien:: modules and their libraries
8
10 In your Build.PL:
11 use Alien::Base::ModuleBuild;
13 my $builder = Alien::Base::ModuleBuild->new(
15 module_name => 'Alien::MyLibrary',
16 configure_requires => {
18 'Alien::Base::ModuleBuild' => '0.005',
19 'Module::Build' => '0.28'
20 },
21 requires => {
22 'Alien::Base' => '0.005',
23 },
24 alien_name => 'mylibrary', # the pkg-config name if you want
26 # to use pkg-config to discover
27 # system version of the mylibrary
28 alien_repository => {
30 protocol => 'http',
31 host => 'myhost.org',
32 location => '/path/to/tarballs',
33 pattern => qr{^mylibrary-([0-9\.]+)\.tar\.gz$},
34 },
35 # this is the default:
37 alien_build_commands => [
38 "%c --prefix=%s", # %c is a platform independent version of ./configure
39 "make",
40 ],
41 # this is the default for install:
43 alien_install_commands => [
44 "make install",
45 ],
46 alien_isolate_dynamic => 1,
48 );

51 NOTE: Please consider for new development of Aliens that you use
52 Alien::Build and alienfile instead. Like this module they work with
53 Alien::Base. Unlike this module they are more easily customized and
54 handle a number of corner cases better. For a good place to start,
55 please see Alien::Build::Manual::AlienAuthor. Although the Alien-Base
56 / Alien-Build team will continue to maintain this module, (we will
57 continue to fix bugs where appropriate), we aren't adding any new
58 features to this module.
59 This is a subclass of Module::Build, that with Alien::Base allows for
61 easy creation of Alien distributions. This module is used during the
62 build step of your distribution. When properly configured it will
63 use pkg-config to find and use the system version of the library
65 download, build and install the library if the system does not provide
66 it
67
69 alien_check_installed_version
70 [version 0.001]
71 my $version = $abmb->alien_check_installed_version;
73 This function determines if the library is already installed as part of
75 the operating system, and returns the version as a string. If it can't
76 be detected then it should return empty list.
77 The default implementation relies on "pkg-config", but you will
79 probably want to override this with your own implementation if the
80 package you are building does not use "pkg-config".
81 alien_check_built_version
83 [version 0.006]
84 my $version = $amb->alien_check_built_version;
86 This function determines the version of the library after it has been
88 built from source. This function only gets called if the operating
89 system version can not be found and the package is successfully built.
90 The version is returned on success. If the version can't be detected
91 then it should return empty list. Note that failing to detect a
92 version is considered a failure and the corresponding "./Build" action
93 will fail!
94 Any string is valid as a version as far as Alien::Base is concerned.
96 The most useful value would be a number or dotted decimal that most
97 software developers recognize and that software tools can
98 differentiate. In some cases packages will not have a clear version
99 number, in which case the string "unknown" would be a reasonable
100 choice.
101 The default implementation relies on "pkg-config", and other
103 heuristics, but you will probably want to override this with your own
104 implementation if the package you are building does not use
105 "pkg-config".
106 When this method is called, the current working directory will be the
108 build root.
109 If you see an error message like this:
111 Library looks like it installed, but no version was determined
113 After the package is built from source code then you probably need to
115 provide an implementation for this method.
116 alien_extract_archive
118 [version 0.024]
119 my $dir = $amb->alien_extract_archive($filename);
121 This function unpacks the given archive and returns the directory
123 containing the unpacked files.
124 The default implementation relies on Archive::Extract that is able to
126 handle most common formats. In order to handle other formats or
127 archives requiring some special treatment you may want to override this
128 method.
129 alien_do_system
131 [version 0.024]
132 my %result = $amb->alien_do_system($cmd)
134 Similar to Module::Build::do_system, also sets the path and several
136 environment variables in accordance to the object configuration (i.e.
137 "alien_bin_requires") and performs the interpolation of the patterns
138 described in "COMMAND INTERPOLATION" in Alien::Base::ModuleBuild::API.
139 Returns a set of key value pairs including "stdout", "stderr",
141 "success" and "command".
142
144 The documentation for "Module::Build" is broken up into sections:
145 General Usage (Module::Build)
147 This is the landing document for Alien::Base::ModuleBuild's parent
148 class. It describes basic usage and background information. Its
149 main purpose is to assist the user who wants to learn how to invoke
150 and control "Module::Build" scripts at the command line.
151 It also lists the extra documentation for its use. Users and
153 authors of Alien:: modules should familiarize themselves with these
154 documents. Module::Build::API is of particular importance to
155 authors.
156 Alien-Specific Usage (Alien::Base::ModuleBuild)
158 This is the document you are currently reading.
159 Authoring Reference (Alien::Base::Authoring)
161 This document describes the structure and organization of
162 "Alien::Base" based projects, beyond that contained in
163 "Module::Build::Authoring", and the relevant concepts needed by
164 authors who are writing Build.PL scripts for a distribution or
165 controlling "Alien::Base::ModuleBuild" processes programmatically.
166 Note that as it contains information both for the build and use
168 phases of Alien::Base projects, it is located in the upper
169 namespace.
170 API Reference (Alien::Base::ModuleBuild::API)
172 This is a reference to the "Alien::Base::ModuleBuild" API beyond
173 that contained in "Module::Build::API".
174
176 ALIEN_VERBOSE
177 Enables verbose output from M::B::do_system.
178 ALIEN_FORCE
180 Skips checking for an installed version and forces reinstalling the
181 Alien target.
182 ALIEN_INSTALL_TYPE
184 Set to 'share' or 'system' to override the install type. Set to
185 'default' or unset to restore the default.
186 ALIEN_ARCH
188 Set to a true value to install to an arch-specific directory.
189 ALIEN_${MODULENAME}_REPO_${PROTOCOL}_${KEY}
191 Overrides $KEY in the given module's repository configuration
192 matching $PROTOCOL. For example,
193 "ALIEN_OPENSSL_REPO_FTP_HOST=ftp.example.com".
