NAME

App::MechaCPAN::Perl - Mechanize the installation of Perl.

SYNOPSIS

  # Install 5.24 into local/
  user@host:~$ mechacpan perl 5.24

DESCRIPTION

The perl command is used to install perl into local/. This removes the packages dependency on the operating system perl.

Methods

go( \%opts, $version )

There is only a single public function that should be called. This will install the version of perl given in $version using the options in \%opts. The options available are listed in the arguments section below.

$version is either 0 or 1 parameter:

If 0 parameters are given and there is a .perl-version file, it will try and use that as the version to install.
Otherwise, if 0 parameters are given, it will attempt to find and install the newest, stable version of perl.
If the parameter is a major version (5.XX), it will attempt to find and install the newest minor version of that major version.
If the parameter is a minor version (5.XX.X), it will attempt to download and install that exact version.
If the parameter is a file, it will try to use that file as a perl source tarball.
If the parameter is a file, and it contains an executable "bin/perl", it will try to install that file as a binary perl tarball.
If the parameter looks like a URL, it will fetch that URL and try to use it as a perl source tarball.

Arguments

threads

By default, perl is compiled without threads. If you'd like to enable threads, use this argument.

shared-lib

By default, perl will generate a libperl.a file. If you need libperl.so, then use this argument.

build-reusable

Giving this options will change the mode of operation from installing perl into local/ to generating a reusable, relocatable perl archive. This uses the same parameters (i.e. "devel" and "threads") to generate the binary, although do note that the lib/ directory is always included unless "skip-lib" is provided. The archive name will generally reflect what systems it can run on. Because of the nature of how perl builds binaries, it cannot guarantee that it will work on any given system, but if will have the best luck if you use it on the same version of a distribution.

Once you have a reusable binary archive, App::MechaCPAN::Perl can use that archive as a source file and install the binaries into the local directory. This can be handy if you are building a lot of identical systems and only want to build perl once.

jobs

How many make jobs to use when running make. The code must guess if make supports running multiple jobs, and as such, it may not work for all versions of make. Defaults to 2.

skip-tests

Test for perl are ran by default. If you are sure that the tests will pass and you want to save some time, you can skip the testing phase with this option.

smart-tests

As an alternative to telling App::MechaCPAN::Perl to use tests or not, App::MechaCPAN::Perl can try to be clever and guess if it needs to run tests. If there is a .perl-version file and it is the same version that is being installed, then tests will be skips. The thinking is that if there is a .perl-version file, then it is likely that perl has been installed and tested before.

smart-tests are off by default, but are enabled by App::MechaCPAN::Deploy when there is a cpanfile.snapshot file. See "smart-tests" in App::MechaCPAN::Install.

skip-local

Since perl and modules will be installed by App::MechaCPAN into local/, by default local/ will be added to @INC. This means that if you use the local/ installed perl you do not need to use local::lib or other @INC tricks. If you want to suppress this behavior, use this flag.

skip-lib

If a lib/ directory exists in the same directory as the local/ directory, then lib/ will also bee added to @INC. This is helpful if you're installing to run an application that includes a lib/ directory. If you do not want this to be added, use this flag.

devel

By default, perl will not compile a development version without -Dusedevel passed to configure. This adds that flag to the configure step so that perl will install unstable development versions. This is NOT recommended except for testing.

WIN32 LIMITATION

Building perl from scratch on Win32 is nothing like building it on other platforms. At this point, the perl command does not work on Win32.
