Notes on Perl
|
|
-------------
|
|
|
|
For our scripts, we rely quite a bit on Perl, and increasingly on
|
|
some core Perl modules. These Perl modules are part of the Perl
|
|
source, so if you build Perl on your own, you should be set.
|
|
|
|
However, if you install Perl as binary packages, the outcome might
|
|
differ, and you may have to check that you do get the core modules
|
|
installed properly. We do not claim to know them all, but experience
|
|
has told us the following:
|
|
|
|
- on Linux distributions based on Debian, the package 'perl' will
|
|
install the core Perl modules as well, so you will be fine.
|
|
- on Linux distributions based on RPMs, you will need to install
|
|
'perl-core' rather than just 'perl'.
|
|
|
|
You MUST have at least Perl version 5.10.0 installed. This minimum
|
|
requirement is due to our use of regexp backslash sequence \R among
|
|
other features that didn't exist in core Perl before that version.
|
|
|
|
Notes on Perl on Windows
|
|
------------------------
|
|
|
|
There are a number of build targets that can be viewed as "Windows".
|
|
Indeed, there are VC-* configs targeting VisualStudio C, as well as
|
|
MinGW and Cygwin. The key recommendation is to use "matching" Perl,
|
|
one that matches build environment. For example, if you will build
|
|
on Cygwin be sure to use the Cygwin package manager to install Perl.
|
|
For MSYS builds use the MSYS provided Perl. For VC-* builds we
|
|
recommend ActiveState Perl, available from
|
|
http://www.activestate.com/ActivePerl.
|
|
|
|
Notes on Perl on VMS
|
|
--------------------
|
|
|
|
You will need to install Perl separately. One way to do so is to
|
|
download the source from http://perl.org/, unpacking it, reading
|
|
README.vms and follow the instructions. Another way is to download a
|
|
.PCSI file from http://www.vmsperl.com/ and install it using the
|
|
POLYCENTER install tool.
|
|
|
|
Notes on Perl modules we use
|
|
----------------------------
|
|
|
|
We make increasing use of Perl modules, and do our best to limit
|
|
ourselves to core Perl modules to keep the requirements down. There
|
|
are just a few exceptions:
|
|
|
|
Test::More We require the minimum version to be 0.96, which
|
|
appeared in Perl 5.13.4, because that version was
|
|
the first to have all the features we're using.
|
|
This module is required for testing only! If you
|
|
don't plan on running the tests, you don't need to
|
|
bother with this one.
|
|
|
|
Text::Template This module is not part of the core Perl modules.
|
|
As a matter of fact, the core Perl modules do not
|
|
include any templating module to date.
|
|
This module is absolutely needed, configuration
|
|
depends on it.
|
|
|
|
To avoid unnecessary initial hurdles, we have bundled a copy of the
|
|
following modules in our source. They will work as fallbacks if
|
|
these modules aren't already installed on the system.
|
|
|
|

Notes on installing a perl module
|
|
---------------------------------
|
|
|
|
There are a number of ways to install a perl module. In all
|
|
descriptions below, Text::Template will server as an example.
|
|
|
|
1. for Linux users, the easiest is to install with the use of your
|
|
favorite package manager. Usually, all you need to do is search
|
|
for the module name and to install the package that comes up.
|
|
|
|
On Debian based Linux distributions, it would go like this:
|
|
|
|
$ apt-cache search Text::Template
|
|
...
|
|
libtext-template-perl - perl module to process text templates
|
|
$ sudo apt-get install libtext-template-perl
|
|
|
|
Perl modules in Debian based distributions use package names like
|
|
the name of the module in question, with "lib" prepended and
|
|
"-perl" appended.
|
|
|
|
2. Install using CPAN. This is very easy, but usually requires root
|
|
access:
|
|
|
|
$ cpan -i Text::Template
|
|
|
|
Note that this runs all the tests that the module to be installed
|
|
comes with. This is usually a smooth operation, but there are
|
|
platforms where a failure is indicated even though the actual tests
|
|
were successful. Should that happen, you can force an
|
|
installation regardless (that should be safe since you've already
|
|
seen the tests succeed!):
|
|
|
|
$ cpan -f -i Text::Template
|
|
|
|
Note: on VMS, you must quote any argument that contains upper case
|
|
characters, so the lines above would be:
|
|
|
|
$ cpan -i "Text::Template"
|
|
|
|
and:
|
|
|
|
$ cpan -f -i "Text::Template"
|
