NAME

perlvos − Perl for Stratus OpenVOS

SYNOPSIS

This file contains notes for building perl on the Stratus OpenVOS operating system. Perl is a scripting or macro language that is popular on many systems. See perlbook for a number of good books on Perl.

These are instructions for building Perl from source. This version of Perl requires the dynamic linking support that is found in OpenVOS Release 17.1 and thus is not supported on OpenVOS Release 17.0 or earlier releases.

If you are running VOS Release 14.4.1 or later, you can obtain a pre-compiled, supported copy of perl by purchasing the GNU Tools product from Stratus Technologies.

BUILDING PERL FOR OPENVOS

To build perl from its source code on the Stratus V Series platform you must have OpenVOS Release 17.1.0 or later, GNU Tools Release 3.5 or later, and the C/POSIX Runtime Libraries.

Follow the normal instructions for building perl; e.g, enter bash, run the Configure script, then use "gmake" to build perl.

INSTALLING PERL IN OPENVOS

1.

After you have built perl using the Configure script, ensure that you have modify and default write permission to ">system>ported" and all subdirectories. Then type

     gmake install

2.

While there are currently no architecture-specific extensions or modules distributed with perl, the following directories can be used to hold such files (replace the string VERSION by the appropriate version number):

     >system>ported>lib>perl5>VERSION>i786

3.

Site-specific perl extensions and modules can be installed in one of two places. Put architecture-independent files into:

     >system>ported>lib>perl5>site_perl>VERSION

Put site-specific architecture-dependent files into one of the following directories:

     >system>ported>lib>perl5>site_perl>VERSION>i786

4.

You can examine the @INC variable from within a perl program to see the order in which Perl searches these directories.

USING PERL IN OPENVOS

Restrictions of Perl on OpenVOS
This port of Perl version 5 prefers Unix-style, slash-separated pathnames over OpenVOS-style greater-than-separated pathnames. OpenVOS-style pathnames should work in most contexts, but if you have trouble, replace all greater-than characters by slash characters. Because the slash character is used as a pathname delimiter, Perl cannot process OpenVOS pathnames containing a slash character in a directory or file name; these must be renamed.

This port of Perl also uses Unix-epoch date values internally. As long as you are dealing with ASCII character string representations of dates, this should not be an issue. The supported epoch is January 1, 1980 to January 17, 2038.

See the file pod/perlport.pod for more information about the OpenVOS port of Perl.

TEST STATUS

A number of the perl self-tests fails for various reasons; generally these are minor and due to subtle differences between common POSIX-based environments and the OpenVOS POSIX environment. Ensure that you conduct sufficient testing of your code to guarantee that it works properly in the OpenVOS environment.

SUPPORT STATUS

I’m offering this port "as is". You can ask me questions, but I can’t guarantee I’ll be able to answer them. There are some excellent books available on the Perl language; consult a book seller.

If you want a supported version of perl for OpenVOS, purchase the OpenVOS GNU Tools product from Stratus Technologies, along with a support contract (or from anyone else who will sell you support).

Opportunity


Personal Opportunity - Free software gives you access to billions of dollars of software at no cost. Use this software for your business, personal use or to develop a profitable skill. Access to source code provides access to a level of capabilities/information that companies protect though copyrights. Open source is a core component of the Internet and it is available to you. Leverage the billions of dollars in resources and capabilities to build a career, establish a business or change the world. The potential is endless for those who understand the opportunity.

Business Opportunity - Goldman Sachs, IBM and countless large corporations are leveraging open source to reduce costs, develop products and increase their bottom lines. Learn what these companies know about open source and how open source can give you the advantage.





Free Software


Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.


Free Office Software - The Libre Office suite provides top desktop productivity tools for free. This includes, a word processor, spreadsheet, presentation engine, drawing and flowcharting, database and math applications. Libre Office is available for Linux or Windows.





Free Books


The Free Books Library is a collection of thousands of the most popular public domain books in an online readable format. The collection includes great classical literature and more recent works where the U.S. copyright has expired. These books are yours to read and use without restrictions.


Source Code - Want to change a program or know how it works? Open Source provides the source code for its programs so that anyone can use, modify or learn how to write those programs themselves. Visit the GNU source code repositories to download the source.





Education


Study at Harvard, Stanford or MIT - Open edX provides free online courses from Harvard, MIT, Columbia, UC Berkeley and other top Universities. Hundreds of courses for almost all major subjects and course levels. Open edx also offers some paid courses and selected certifications.


Linux Manual Pages - A man or manual page is a form of software documentation found on Linux/Unix operating systems. Topics covered include computer programs (including library and system calls), formal standards and conventions, and even abstract concepts.
