Perlcc creates standalone executables from Perl programs, using the code generators provided by the B module. At present, you may either create executable Perl bytecode, using the -B option, or generate and compile C files using the standard and 'optimised' C backends. To build and install Perl and many of the thousands of useful Perl modules you need to have a compiler. For macOS the easiest way to get a compiler is to install 'Command Line Tools for Xcode' (about 100 Megs), either directly or through Xcode (several Gigs), both available from Apple Developer downloads.

When searching a Perl module, sooner or later you will end up on one of two sites sites providing information about CPAN modules.Both Meta CPAN, and search.cpan.orgwill show you a link to download the module, but in most cases that's not what you need.

So how do you really install Perl modules from CPAN?

(As always, some people will disagree with the recommendations below, they probably have not readthe article of Dave Cross, or reachedother conclusions.)

In most cases the installation of a CPAN module works just as installing an app from the Apple Appstore or the Google Play.Except, that these modules are all open source and free software.

Depending on the Operating System and which Perl distribution you have, the specific instructions differ.In order to make the examples clearer, let's try to install the module called Try::Tiny.

It has its description both on Meta CPAN and onsearch.cpan.org. Both have the Download linksthat we won't click on.

Cases

Strawberry Perl or DWIM Perl on Windows

Strawberry Perl,comes with an already configured cpan client. We will use this client to install modules directly from CPAN:

Open the Command Window (Start -> Run -> type in cmd) When you get the 'DOS' prompttype in cpan Path::Tiny.Please note, module names are case sensitive,so typing cpan path::tiny or cpan PATH::TINY will not work!

Also, in normal circumstances, the cpan client is expecting the full name of the module, not one part of the name,and not the name of the zip-file.So cpan Path or cpan Tiny will attempt to install different modules.(One called Path, the other one called Tiny.)

What you need to do is type in:

ActivePerl

There is a graphical tool for this as well, but it might be more simple just to open theCommand Window (Start -> Run -> type cmd). When you get the 'DOS' prompt, type inppm install Path::Tiny. Please note, this too is case sensitive!

The problem you might encounter is that this command uses the 'CPAN store' of ActiveState that for varioustechnical and legal reasons does not carry all the the modules from CPAN. It can also be out-of datecarrying older versions of the modules. On newer versions of ActivePerl you can also enable a realcpan-client that will access the CPAN server just as it does in the case of Strawberry/DWIM Perl above.

GitPerl

TBD.

Cygwin Perl

TBD. Cygwin.

Debian/Ubuntu Linux

If you have root rights, and if you use the system perl located in /usr/bin/perl,then probably the best is to try to install from the package management system of your Linux distribution.If you don't have root rights, you could ask your system administrator to do it on your behalf.

Apparently there is a nice way to find out if a Perl module is on Debian or Ubuntu.

If the module you are looking for is not available in the repositories of your Debian/Ubuntu/etc. distribution(and there are only about 10% of the modules available), or if you don't use the system Perl,then you can follow the instructions with cpan/cpanm below.

To install for the system-perl as root you can use either aptitude or apt-getdepending on your personal preferences.

If the name of the module in Perl-land is Path::Tiny, then the name of the package in Debian/Ubuntu-landis most likely going to be libpath-tiny-perl.

RedHat/Fedora/CentOS Linux

Just as in the case of Debian/Ubuntu above, the instructions here are relevant ifyou use the system perl located in /usr/bin/perl and if you haveroot rights:

Using the package management system:

As Dave Cross mentioned, if you don't know the name of the RH package, you can also use

The subtle difference is that the former installs the named RPM whereas the secondinstalls the RPM that provides the named Perl module.

So if you would like to install the Path::Tiny module then the second command isactually the better one.

If your vendor does not carry this Perl package, you can add other RPM repositories.Check out EPEL, andthe Magnum Solutions CPAN RPM Repositorymaintained by Dave Cross.

Mac OSX

Follow the instructions with cpan/cpanm below.

Using the cpan client

While the cpan program comes with most operating system,and it works well after some configuration, there is probably a better,and certainly lighter solution called cpan minus or cpanm.

Using cpanm

This is for Linux and OSX systems. (For Windows, see described above.)

First, if you don't have it installed yet,then install cpan minus by typing

Once it is installed type:
