General Notes
|
|
-------------
|
|
|
|
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.
|
|
|
|
Perl on Windows
|
|
---------------
|
|
|
|
There are a number of build targets that can be viewed as "Windows".
|
|
Indeed, there are `VC-*` configs targeting Visual Studio C, as well as
|
|
MinGW and Cygwin. The key recommendation is to use a Perl installation
|
|
that matches the 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 Strawberry Perl, from <http://strawberryperl.com>.
|
|
An alternative is ActiveState Perl, from <http://www.activestate.com/ActivePerl>
|
|
for which you may need to explicitly select the Perl module Win32/Console.pm
|
|
available via <https://platform.activestate.com/ActiveState>.
|
|
|
|
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.md` 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.
|
|
|
|
Perl on NonStop
|
|
---------------
|
|
|
|
Perl is installed on HPE NonStop platforms as part of the Scripting Languages
|
|
package T1203PAX file. The package is shipped as part of a NonStop RVU
|
|
(Release Version Updates) package. Individual SPRs (Software Product Release)
|
|
representing fixes can be obtained from the Scout website at
|
|
<https://h22204.www2.hpe.com/NEP>. Follow the appropriate set of installation
|
|
instructions for your operating system release as described in the
|
|
Script Language User Guide available from the NonStop Technical Library.
|
|
|
|
Required Perl modules
|
|
---------------------
|
|
|
|
We do our best to limit ourselves to core Perl modules to keep the
|
|
requirements down. There are just a few exceptions.
|
|
|
|
* Text::Template this is required *for building*
|
|
|
|
To avoid unnecessary initial hurdles, we include a copy of this module
|
|
in the source. It will work as a fallback if the module isn't already
|
|
installed.
|
|
|
|
* `Test::More` this is required *for testing*
|
|
|
|
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.
|
|
|
|
Notes on installing a Perl module
|
|
---------------------------------
|
|
|
|
There are a number of ways to install a perl module. In all
|
|
descriptions below, `Text::Template` will serve 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 uppercase
|
|
characters, so the lines above would be:
|
|
|
|
$ cpan -i "Text::Template"
|
|
|
|
and:
|
|
|
|
$ cpan -f -i "Text::Template"
|
