How to install Perl on a Unix system
This web page explains how to install the Perl programming language from source code under Unix.
First, download the Perl source code. The "perl.org" website offers a
convenient way to do this at www.perl.org. The file is called something like
perl-5.14.1.tar.gz. The numbers after the
perl- are the version number of Perl. "Tar" is a form of file archive. "Gz" indicates that the file is compressed with the
gzip utility, which is usually installed on Unix systems.
Extract the files from the archive with the command
tar xfz perl-5.14.1.tar.gz
This creates a directory (folder) called
puts all the files into it.
Change to the new directory:
There are three stages to installing Perl. First of all, run the script
Configure in order that Perl can understand what operating system it is being installed on:
The initial output looks something like this:
$ ./Configure Beginning of configuration questions for perl5. Checking echo to see how to suppress newlines... ...using -n. The star should be here-->* First let's make sure your kit is complete. Checking... Looks good...
This script asks a lot of questions. Usually it is OK to just press "Enter" each time to accept the default answer. When installing Perl, it is possible to install it into a user directory with an answer like
Installation prefix to use? (~name ok) [/usr/local] /home/ben/software/install
This will make it possible to, for example, install Perl modules
without using a special privileged account. Also note that on Linux
systems such as Debian or Ubuntu, the "system Perl"
/usr/bin/perl is used in various ways by the system
and it is better not to upgrade or otherwise alter it in any way.
After Configure has finished, it is then necessary to build and
install Perl. These stages are done via the
make make install
There is also a
make test option to test whether Perl has
built correctly, if required.
make install has completed, Perl is installed in
the computer and nothing further needs to be done.
