NAME
perlvos - Perl for Stratus VOS
SYNOPSIS
This file contains notes for building perl on the Stratus VOS 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 is not
supported on VOS Release 14.2 or earlier releases. If you have a Continuum platform
running VOS Release 14.3 through 14.7, download Perl from the Stratus Anonymous FTP site
at ftp://ftp.stratus.com/pub/vos/posix/ga/continuum/continuum.html. If you have a V
Series platform running VOS Release 15.0 or later, or if you have a V Series platform
running OpenVOS Release 17.0 or later, download Perl from
ftp://ftp.stratus.com/pub/vos/posix/ga/v-series/v-series.html. The perl distribution
files on the Stratus anonymous FTP site are stored in a format called a "bundled file".
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 (or later) of the VOS GNU C/C++ and GNU Tools
product from Stratus Technologies.
BUILDING PERL FOR VOS
To build perl from its source code on the Stratus Continuum platform, you must be have VOS
Release 14.5.0 or later, the STCP product, and the GNU C/C++ and GNU Tools, Release 2.0.1
or later. On the V Series platform you must have VOS Release 15.0.0 or later, and any
version of the GNU C/C++ and GNU Tools product.
To build full perl using the supplied Configure script and makefiles, change to the "vos"
subdirectory and type the command "compile_full_perl" or "start_process
compile_full_perl". This will configure, build, and test perl.
INSTALLING PERL IN VOS
1. If 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>7100
>system>ported>lib>perl5>VERSION>8000
>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>7100
>system>ported>lib>perl5>site_perl>VERSION>8000
>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 VOS
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.
See the file pod/perlport.pod for more information about the VOS port of Perl.
Handling of underflow and overflow
Prior to VOS Release 14.7.0, VOS does not support automatically mapping overflowed
floating-point values to +infinity, nor automatically mapping underflowed floating-point
values to zero, unlike many other platforms. The Perl pack function has been modified to
perform such mapping in software on VOS. Performing other floating-point computations
that underflow or overflow will probably result in SIGFPE. Don't push your luck.
As of VOS Release 14.7.0 or later, the VOS POSIX runtime sets up the PA-RISC and IA-32
hardware floating-point status register so that the overflow and underflow exceptions do
not trap, but instead automatically convert the result to infinity or zero, as
appropriate. As of this writing, there are still floating-point operations that can trap,
for example, subtracting two infinite values. This is recorded as suggestion posix-1022,
which has been fixed in VOS Release 15.2 and higher.
TEST STATUS
When Perl 5.9.0 is built using the native build process on VOS Release 14.7.0 and GNU
C++/GNU Tools 2.0.2a, all but nine attempted tests either pass or result in TODO (ignored)
failures. The tests that fail are:
t/io/dup, test 2 t/io/tell, test 28 t/op/pack, test 0 ext/B/t/bytecode, test 1
ext/Devel/Peek/t/Peek, test 1 ext/Encode/t/enc_module, test 1 ext/IO/t/io_dup, test 2
lib/ExtUtils/t/MM_Unix, test 94 lib/Net/ing/t/450_service, test 8
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 VOS, purchase the VOS GNU C/C++ and GNU Tools
Release 2.0.1 (or later) product from Stratus Technologies, along with a support contract
(or from anyone else who will sell you support).
