As a special service "Fossies" has tried to format the requested text file into HTML format (style: standard) with prefixed line numbers. Alternatively you can here view or download the uninterpreted source code file.

    1 If you read this file _as_is_, just ignore the funny characters you
    2 see. It is written in the POD format (see pod/perlpod.pod) which is
    3 specially designed to be readable as is.

    5 =head1 NAME
    6 
    7 perlvos - Perl for Stratus OpenVOS
    8 
    9 =head1 SYNOPSIS
   10 
   11 This file contains notes for building perl on the Stratus OpenVOS
   12 operating system.  Perl is a scripting or macro language that is
   13 popular on many systems.  See L<perlbook> for a number of good books
   14 on Perl.
   15 
   16 These are instructions for building Perl from source.  This version of
   17 Perl requires the dynamic linking support that is found in OpenVOS
   18 Release 17.1 and thus is not supported on OpenVOS Release 17.0 or
   19 earlier releases.
   20 
   21 If you are running VOS Release 14.4.1 or later, you can obtain a
   22 pre-compiled, supported copy of perl by purchasing the GNU Tools
   23 product from Stratus Technologies.
   24 
   25 =head1 BUILDING PERL FOR OPENVOS
   26 
   27 To build perl from its source code on the Stratus V Series platform
   28 you must have OpenVOS Release 17.1.0 or later, GNU Tools Release
   29 3.5 or later, and the C/POSIX Runtime Libraries.
   30 
   31 Follow the normal instructions for building perl; e.g, enter bash, run
   32 the Configure script, then use "gmake" to build perl.

   35 
   36 =over 4
   37 
   38 =item 1
   39 
   40 After you have built perl using the Configure script, ensure that you
   41 have modify and default write permission to C<< >system>ported >> and
   42 all subdirectories.  Then type
   43 
   44      gmake install
   45 
   46 =item 2
   47 
   48 While there are currently no architecture-specific extensions or
   49 modules distributed with perl, the following directories can be
   50 used to hold such files (replace the string VERSION by the
   51 appropriate version number):
   52 
   53      >system>ported>lib>perl5>VERSION>i786
   54 
   55 =item 3
   56 
   57 Site-specific perl extensions and modules can be installed in one of
   58 two places.  Put architecture-independent files into:
   59 
   60      >system>ported>lib>perl5>site_perl>VERSION
   61 
   62 Put site-specific architecture-dependent files into one of the
   63 following directories:
   64 
   65      >system>ported>lib>perl5>site_perl>VERSION>i786
   66 
   67 =item 4
   68 
   69 You can examine the @INC variable from within a perl program
   70 to see the order in which Perl searches these directories.

   74 =head1 USING PERL IN OPENVOS
   75 
   76 =head2 Restrictions of Perl on OpenVOS
   77 
   78 This port of Perl version 5 prefers Unix-style, slash-separated
   79 pathnames over OpenVOS-style greater-than-separated pathnames.
   80 OpenVOS-style pathnames should work in most contexts, but if you have
   81 trouble, replace all greater-than characters by slash characters.
   82 Because the slash character is used as a pathname delimiter, Perl
   83 cannot process OpenVOS pathnames containing a slash character in a
   84 directory or file name; these must be renamed.
   85 
   86 This port of Perl also uses Unix-epoch date values internally.
   87 As long as you are dealing with ASCII character string
   88 representations of dates, this should not be an issue.  The
   89 supported epoch is January 1, 1980 to January 17, 2038.
   90 
   91 See the file pod/perlport.pod for more information about the OpenVOS
   92 port of Perl.
   93 
   94 =head1 TEST STATUS
   95 
   96 A number of the perl self-tests fails for various reasons; generally
   97 these are minor and due to subtle differences between common
   98 POSIX-based environments and the OpenVOS POSIX environment.  Ensure
   99 that you conduct sufficient testing of your code to guarantee that it
  100 works properly in the OpenVOS environment.
  101 
  102 =head1 SUPPORT STATUS
  103 
  104 I'm offering this port "as is".  You can ask me questions, but I
  105 can't guarantee I'll be able to answer them.  There are some
  106 excellent books available on the Perl language; consult a book
  107 seller.
  108 
  109 If you want a supported version of perl for OpenVOS, purchase the
  110 OpenVOS GNU Tools product from Stratus Technologies, along with a
  111 support contract (or from anyone else who will sell you support).
