=head1 NAME
-README.vos - Perl for Stratus VOS
+perlvos - Perl for Stratus OpenVOS
=head1 SYNOPSIS
-This file contains notes for building perl on the Stratus VOS
+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 L<perlbook> for a number of good
-books on Perl.
-
-These are instructions for building Perl from source. Most people can
-simply download a pre-compiled distribution from the VOS anonymous FTP
-site. If you are running VOS Release 14.2.0 or earlier, download Perl
-from ftp://ftp.stratus.com/pub/vos/posix/alpha/alpha.html If you are
-running VOS Release 14.3.0 or later, download Perl from
-ftp://ftp.stratus.com/pub/vos/posix/ga/ga.html Instructions for
-unbundling the Perl distribution file are at
-ftp://ftp.stratus.com/pub/vos/utility/utility.html
-
-If you are running VOS Release 14.4.1 or later, you can obtain a
-pre-compiled, supported copy of perl by purchasing Release 2.0.1
-of the VOS GNU C++ and GNU Tools product from Stratus
-Technologies.
-
-=head2 Multiple methods to build perl for VOS
-
-If you elect to build perl from its source code, you have several
-different ways that you can build perl. The method that you use
-depends on the version of VOS that you are using and on the
-architecture of you Stratus hardware platform.
-
-=over 5
-
-=item 1
-
-If you have a Stratus XA2000 (Motorola 68k-based) platform, you
-must build perl using the alpha version of VOS POSIX support and
-using the VOS Standard C Cross-compiler. You must build perl on
-VOS Release 14.1.0 (or later) on an XA/R or Continuum platform.
-
-This version of perl is properly called "miniperl" because it
-does not contain the full perl functionality.
-
-You must build perl with the compile_perl.cm command macro found
-in the vos subdirectory.
-
-=item 2
-
-If you have a Stratus XA/R (Intel i860-based) platform, you must
-build perl using the alpha version of VOS POSIX support and using
-the VOS Standard C compiler or cross-compiler. You must build
-perl on VOS Release 14.1.0 (or later) on an XA/R or Continuum
-platform.
-
-This version of perl is properly called "miniperl" because it
-does not contain the full perl functionality.
-
-You must build perl with the compile_perl.cm command macro found
-in the vos subdirectory.
-
-=item 3
-
-If you have a Stratus Continuum (PARISC-based) platform that is
-running a version of VOS earlier than VOS 14.3.0, you must build
-perl using the alpha version of VOS POSIX support and using the
-VOS Standard C compiler or cross-compiler. You must build perl
-on VOS Release 14.1.0 (or later) on an XA/R or Continuum
-platform.
-
-This version of perl is properly called "miniperl" because it
-does not contain the full perl functionality.
-
-You must build perl with the compile_perl.cm command macro found
-in the vos subdirectory.
-
-=item 4
-
-If you have a Stratus Continuum (PARISC-based) platform that is
-running VOS Release 14.3.0 through VOS Release 14.4.0, you must
-build perl using the generally-available version of VOS POSIX
-support, and using either the VOS Standard C compiler or the VOS
-GNU C compiler. You must build perl on VOS Release 14.3.0 (or
-later) on a Continuum platform.
-
-This version of perl is properly called "miniperl" because it
-does not contain the full perl functionality.
-
-You must build perl with the compile_perl.cm command macro found

-=item 5
-
-If you have a Stratus Continuum (PA-RISC-based) platform that is
-running VOS Release 14.4.1 or later, you must build perl using
-the generally-available version of VOS POSIX support. You must
-use the VOS GNU C compiler and the VOS GNU Tools product. You
-must build perl on VOS Release 14.4.1 (or later) on a Continuum
-platform.
-
-This version of perl is properly called "full perl" because it
-contains the full perl functionality.
-
-You must use the supplied Configure script and makefiles to build
-perl.

-
-=head2 Stratus POSIX Support
-
-Note that there are two different implementations of POSIX.1
-support on VOS. There is an alpha version of POSIX that is
-available from the Stratus anonymous ftp site
-( ftp://ftp.stratus.com/pub/vos/posix/alpha/alpha.html ). There
-is a generally-available version of POSIX that comes with VOS
-Release 14.3.0 or higher. This port of POSIX will compile and
-bind with either version of POSIX.
-
-Most of the Perl features should work on VOS regardless of which
-version of POSIX that you are using. However, the alpha version
-of POSIX is missing a number of key functions, and therefore any
-attempt by perl.pm to call the following unimplemented POSIX
-functions will result in an error message and an immediate and
-fatal call to the VOS debugger. They are "dup", "fork", and
-"waitpid". The lack of these functions prevents you from
-starting VOS commands and grabbing their output in perl. The
-workaround is to run the commands outside of perl, then have perl
-process the output file. These functions are all available in
-the generally-available version of POSIX.

-=head1 INSTALLING PERL IN VOS
+popular on many systems. See L<perlbook> for a number of good books
+on Perl.
-=head2 Compiling Perl 5 on VOS
+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.
-Before you can build Perl 5 on VOS, you need to have or acquire the
-following additional items.
-
-=over 5
-
-=item 1
-
-The VOS Standard C Compiler (or the VOS Standard C
-Cross-Compiler) and the VOS C Runtime. If you are using
-the generally-available version of POSIX support, you may
-instead use the VOS GNU C/C++ Compiler. These are
-standard Stratus products.
-
-=item 2
-
-Either the VOS OS TCP/IP or STCP product set. If you are
-building with the alpha version of POSIX you need the OS
-TCP/IP product set. If you are building with the
-generally-available version of POSIX you need the STCP
-product set. These are standard Stratus products.
-
-=item 3
-
-Either the alpha or generally-available version of the VOS
-POSIX.1 environment.
-
-The alpha version of POSIX.1 support is available on the
-Stratus FTP site. Login anonymously to ftp.stratus.com and
-get the file /pub/vos/posix/alpha/posix.save.evf.gz in
-binary file-transfer mode. Or use the Uniform Resource
-Locator (URL)
-ftp://ftp.stratus.com/pub/vos/posix/alpha/posix.save.evf.gz from
-your web browser. Instructions for unbundling this file
-are at ftp://ftp.stratus.com/pub/vos/utility/utility.html
-This is not a standard Stratus product.
-
-In VOS Release 14.3.0, the generally-available version of
-POSIX.1 support is bundled with the VOS Standard C compiler
-(or Standard C Cross-Compiler). In VOS Release 14.4.0 or
-higher, it is also bundled with the VOS C Runtime. These
-are standard Stratus products.
-
-=item 4
-
-You must compile this version of Perl 5 on VOS Release
-14.1.0 or higher because some of the perl source files
-contain more than 32,767 source lines. Due to VOS
-release-compatibility rules, this port of perl may not
-execute on VOS Release 12 or earlier.
-
-=item 5
-
-If you are using the generally-available version of VOS POSIX
-support, then you should also acquire the VOS GNU C/C++ Compiler
-and GNU Tools product. When perl is built with this version of
-POSIX support, it assumes that it can find "bash", "sed" and
-other POSIX-compatible commands in the directory
-/system/gnu_library/bin.
-
-=back
-
-To build perl using the supplied VOS command macros, change to
-the "vos" subdirectory and type the command "compile_perl
--processor X", where X is the processor type (mc68020, i80860,
-pa7100, pa8000) that you wish to use. Note that the
-generally-available version of POSIX.1 support is not available
-for the mc68020 or i80860 processors.
-
-Use the "-version alpha" control argument to build perl with
-the alpha version of POSIX support, and use the "-version
-ga" control argument to build it with the
-generally-available version of POSIX. The default is "ga".
-
-Use the "-compiler cc" control argument to build perl with
-the VOS Standard C compiler. Use the "-compiler gcc"
-control argument to build it with the GNU GCC compiler. The
-default is "cc".
-
-You must have purchased the VOS Standard C Cross Compiler in
-order to compile perl for a processor type that is different
-from the processor type of the module.
-
-Note that code compiled for the pa7100 processor type can
-execute on the PA7100, PA8000, PA8500 and PA8600 processors, and
-that code compiled for the pa8000 processor type can execute on
-the PA8000, PA8500 and PA8600 processors.
-
-To build perl using the supplied Configure script and makefiles,
-execute the following commands.
+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.
- !add_library_path command >system>gnu_library>bin -after '(current_dir)'
- !bash
- gzip -d perl-5.8.0.tar.gz
- tar -xvf perl-5.8.0.tar
- cd perl-5.8.0
- Configure -d
- gmake

-If you wish to run the test cases, type:
+To build perl from its source code on the Stratus V Series platform

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

-If perl is built with the alpha version of VOS POSIX.1 support
-and if it attempts to call an unimplemented VOS POSIX.1
-function, it will print a fatal error message and enter the VOS
-debugger. This error is not recoverable. See vos_dummies.c for

-=head2 Restrictions of Perl on VOS

-This port of Perl version 5 to VOS prefers Unix-style,
-slash-separated pathnames over VOS-style greater-than-separated
-pathnames. VOS-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 VOS 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.

+=head1 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.
