ActivePerl FAQ - Availability and Installation

NAME

ActivePerl-faq1 - Availability and Installation

DESCRIPTION

Getting, installing, and using Perl.

What is Perl?

Perl is a scripting language widely used for system administration and programming on the World Wide Web. It originated in the UNIX community and has a strong UNIX slant, but usage on Windows is growing rapidly. ActivePerl is a port of core Perl to Windows.

perl (small 'p') is the program used to interpret the Perl language.

Where can I get tons of information about Perl?

Extensive online documentation is included with Perl itself. You can read the documentation with the perldoc command, as in perldoc document_name. You should start with the perl document and the perlfaq document. For information on other ways of accessing the Perl documentation (including HTML versions of this documentation), see Where can I get documentation on ActivePerl?.

To get more information about Perl, check out these URLs:

There are several good books about Perl. The premier book on ActivePerl is Learning Perl On Win32 Systems By Schwartz, Olson, and Christiansen (O'Reilly & Associates, 1997). This is the Gecko book, and has a picture of a gecko (little chubby lizard with big toes and a smile) on the front cover.

For general perl, two books to consider are Programming Perl, 3rd Edition, by Larry Wall, Tom Christiansen and Randal L. Schwartz (O'Reilly & Associates, 1996) and Learning Perl, 3rd Edition, by Randal L. Schwartz (O'Reilly & Associates, 1993). These are referred to by Perl enthusiasts as the Camel book and the Llama book, respectively.

If you are new to Perl and there are any terms mentioned in this FAQ that you don't get, try one of the above resources. See the perlbook document that comes with Perl for more information.

Where can I get the ActivePerl interpreter?

ActivePerl is available from the ActiveState home page.

To download ActivePerl from ActiveState, look in this directory:

  http://www.ActiveState.com/ActivePerl

What do I get with ActivePerl?

ActivePerl is a complete, self-installing distribution of Perl based on the standard Perl sources. It is distributed online at the ActiveState site.

"Perl for Win32" generally refers to ActivePerl for Windows.

How do I install ActivePerl for Linux?

To install:

    tar -xzf ActivePerl-5.6.1.6XX-i686-linux.tar.gz
    cd ActivePerl-5.6.1.6XX
    sh install.sh

The installer will prompt you for a location for the installation.

How do I install ActivePerl for Solaris?

Pkgadd Format

This package installs Perl in: /usr/local/ActivePerl-5.6

Copy ActivePerl-5.6.1.6XX-sun4-solaris.gz into a temporary directory.

To install:

    gunzip ActivePerl-5.6.1.6XX-sun4-solaris.gz
    pkgadd -d ActivePerl-5.6.1.6XX-sun4-solaris

pkgadd will prompt you for the installation location.

ActiveState Installer Format

Copy ActivePerl-5.6.1.6XX-sun4-solaris.tar.gz into a temporary directory.

To install:

    tar -xzf ActivePerl-5.6.1.6XX-sun4-solaris.tar.gz
    cd ActivePerl-5.6.1.6XX
    sh install.sh

The installer will prompt you for a location for the installation.

How do I install ActivePerl for Windows?

Run the MSI installation package to start the installation wizard, which will guide you through the setup, and give you options on what and where to install stuff.

Perl is installed by default in C:\Perl. The drive "C" may vary; it will usually be the same that the operating system is installed on.

If you run Perl at the command prompt, the script will be executed by the first Perl.exe it encounters in the list of paths in the PATH environment variable. To ensure the script is executed by the Perl build you want it to be executed by, you can specify the complete path to the Perl.exe you want to use. (typing perl -v at the command prompt will tell you which version of Perl is currently first in your PATH).

Installing ActivePerl will change your Path environment variable and may change registry settings, such as file associations, which may affect your Web server. If you want to use a previously installed copy of Perl, you will need to modify these settings.

Should I unset any Perl related environment variables before installing ActivePerl?

The short answer is yes!! If you have environment variables such as PERLLIB, PERL5LIB or PERL5OPT set, incompatible versions of modules may be used during the installation process and this may cause the installation to fail. If you have any of these environment variables set, you should temporarily unset the variables, reboot the system and then attempt the installation of ActivePerl. These environment variables are checked by all installed versions of Perl, if you have multiple versions of Perl installed it is not a good idea to set these environment variables globally.

How do I uninstall ActivePerl for Linux?

Debian Package

To uninstall, run:

    dpkg -r ActivePerl

RPM Package

How do I uninstall ActivePerl for Windows?

Goto the Control Panel, and run the Add/Remove Programs applet. Select the ActiveState ActivePerl entry and click Remove to uninstall ActivePerl.

Can I build perl from the source code?

The Perl source code includes complete instructions on building Perl. You can obtain the latest Perl source from:

    http://www.perl.com/CPAN/src/latest.tar.gz

Once you extract the source, read the README file for instructions on compiling Perl.
