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
perl v5.12.5 Last change: 2012-11-03 2
Perl Programmers Reference Guide PERLVOS(1)
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).
