NOTE
       This is a podified version(1,3,5) of the above-mentioned web page, podified by
       Jarkko Hietaniemi 2001-Jan-01.

Binary distribution from HP
       The simplest way to obtain Perl for the MPE/iX is to go either of these
       URLs and follow the instructions within.

What's New in(1,8) Perl for MPE/iX
       June 1, 2000

          Rebuilt to be compatible with mod_perl.  If you plan on using
           mod_perl, you MUST download and install this version(1,3,5) of Perl/iX!

          uselargefiles="undef": not available in(1,8) MPE for POSIX files yet.

          Now bundled with various add-on packages:

                  libnet (as seen on CPAN)

                  libwww-perl (LWP) which lets Perl programs behave like web
                   browsers:

                       1. #!/PERL/PUB/perl
                       2. use LWP::Simple;
                       3. $doc = get('http://www.bixby.org/mark/perlix.html');  # reads the
                          web page into variable $doc

                   (http://www.bixby.org/mark/perlix.html)

                  mod_perl (just the perl portion; the actual DSO will be
                   released soon with Apache/iX 1.3.12 from bixby.org).  This
                   module allows you to write(1,2) high performance persistent Perl
                   CGI scripts and all sorts of cool things.
                   (http://perl.apache.org/)

                   and much much more hiding under /PERL/PUB/.cpan/

                  The CPAN module now works for automatic downloading and
                   installing of add-on packages:

                       1. export FTP_PASSIVE=1
                       2. perl -MCPAN -e shell
                       3. Ignore any terminal I/O related complaints!

                   (http://theoryx5.uwinnipeg.ca/CPAN/data/perl/CPAN.html)

       May 20, 2000

          Updated to version(1,3,5) 5.6.0.  Builds straight out of the box on
           MPE/iX.

          Perl's getpwnam() function which had regressed to being unimple-
           mented on MPE is now implemented once again.

       September 17, 1999

          Migrated from cccd.edu to bixby.org.

Welcome to Perl/iX
       This is the official home page for the HP e3000 MPE/iX (
       http://www.hp.com/go/e3000 ) port of the Perl scripting language (
       http://www.perl.com/ ) which gives you all of the power of C, awk, sed,
       and sh in(1,8) a single language. Check here for the latest news, imple-
       mented functionality, known bugs, to-do list, etc. Status reports about
       major milestones will also be posted to the HP3000-L mailing list (
       http://www.lsoft.com/scripts/wl.exe?SL1=HP3000-L&H=RAVEN.UTC.EDU ) and
       its associated gatewayed newsgroup comp.sys.hp.mpe.

       I'm doing this port because I can't live without Perl on the Unix
       machines that I administer, and I want to have the same power available
       to me on MPE.

       Please send(2,n) your comments, questions, and bug reports directly to me,
       Mark Bixby ( http://www.bixby.org/mark/ ). Or just post them to
       HP3000-L.

       The platform I'm using to do this port is an HP 3000 957RX running
       MPE/iX 6.0 and using the GNU gcc C compiler ( http://jazz.exter-
       nal.hp.com/src/gnu/gnuframe.html ).

       The combined porting wisdom from all of my ports can be found in(1,8) my
       MPE/iX Porting Guide (http://www.bixby.org/mark/porting.html).

       IMPORTANT NOTICE: Yes, I do work for the HP CSY R&D lab, but ALL of the
       software you download from bixby.org is my personal freeware that is
       NOT supported by HP.

System Requirements for Perl/iX
          MPE/iX 5.5 or later. This version(1,3,5) of Perl/iX does NOT run on MPE/iX
           5.0 or earlier, nor does it run on "classic" MPE/V machines.

          If you wish to recompile Perl, you must install both GNUCORE and
           GNUGCC from jazz (http://jazz.exter-
           nal.hp.com/src/gnu/gnuframe.html).

          Perl/iX will be happier on MPE/iX 5.5 if(3,n) you install the MPEKX40B
           extended POSIX filename characters patch, but this is optional.

          Patch LBCJXT6A is required on MPE/iX 5.5 machines in(1,8) order to pre-
           vent Perl/iX from dying with an unresolved external reference to
           _getenv_libc.

          If you will be compiling Perl/iX yourself, you will also need Sys-
           log/iX ( http://www.bixby.org/mark/syslogix.html ) and the
           /BIND/PUB/include and /BIND/PUB/lib portions of BIND/iX (
           http://www.bixby.org/mark/bindix.html ).

How to Obtain Perl/iX
       1.  Download Perl using either FTP.ARPA.SYS or some other client

       2.  Extract the installation script

       3.  Edit the installation script

       4.  Run the installation script

       5.  Convert your *.a system archive libraries to *.sl shared libraries

       Download Perl using FTP.ARPA.SYS from your HP 3000 (the preferred
       method).....

           :HELLO MANAGER.SYS
           :XEQ FTP.ARPA.SYS
           open(2,3,n) ftp.bixby.org
           anonymous
           your@email.address
           bytestream
           cd /pub/mpe
           get perl-5.6.0-mpe.tar.Z /tmp/perl.tar.Z;disc=2147483647
           exit(3,n,1 builtins)

       .....Or download using some other generic web or ftp client (the alter-
       nate method)

       Download the following files (make sure that you use "binary mode" or
       whatever client feature that is 8-bit clean):

          Perl from

               http://www.bixby.org/ftp/pub/mpe/perl-5.6.0-mpe.tar.Z

           or

               ftp://ftp.bixby.org/pub/mpe/perl-5.6.0-mpe.tar.Z

          Upload those files to your HP 3000 in(1,8) an 8-bit clean bytestream
           manner to:

               /tmp/perl.tar.Z

          Then extract the installation script (after both download methods)

               :CHDIR /tmp
               :XEQ TAR.HPBIN.SYS 'xvfopz /tmp/perl.tar.Z INSTALL'

          Edit the installation script

           Examine the accounting structure creation commands and modify if(3,n)
           necessary (adding additional capabilities, choosing a non-system
           volume set(7,n,1 builtins), etc).

               :XEQ VI.HPBIN.SYS /tmp/INSTALL

          Run the installation script.

           The accounting structure will be created and then all files will be
           extracted from the archive.

               :XEQ SH.HPBIN.SYS /tmp/INSTALL

          Convert your *.a system archive libraries to *.sl shared libraries

           You only have to do this ONCE on your MPE/iX 5.5 machine in(1,8) order
           to convert /lib/lib*.a and /usr/lib/lib*.a libraries to their *.sl
           equivalents.  This step should not be necessary on MPE/iX 6.0 or
           later machines because the 6.0 or later update(7,n) process does it for
           you.

               :XEQ SH.HPBIN.SYS /PERL/PUB/LIBSHP3K

How to Compile Perl/iX
       1.  cd src/perl-5.6.0-mpe

       2.  Read the INSTALL file(1,n) for the official instructions

       3.  ./Configure -d

       4.  make

       5.  ./mpeix/relink

       6.  make test (expect approximately 15 out of 11306 subtests to fail,
           mostly due to MPE not supporting hard links, UDP socket(2,7,n) problems,
           and handling exit(3,n,1 builtins)() return codes improperly)

       7.  make install

       8.  Optionally create symbolic links that point to the Perl executable,
           i.e. ln -s /PERL/PUB/PERL /usr/local/bin/perl

Getting Started with Perl/iX
       Create your Perl script files with "#!/PERL/PUB/perl" (or an equivalent
       symbolic link(1,2)) as the first line.  Use the chmod(1,2) command to make sure
       that your script has execute permission. Run your script!

       Be sure to take a look(1,8,3 Search::Dict) at the CPAN module list (
       http://www.cpan.org/CPAN.html ). A wide variety of free Perl software
       is available.  You can automatically download these packages by using
       the CPAN module ( http://theoryx5.uwinnipeg.ca/CPAN/data/perl/CPAN.html
       ).

MPE/iX Implementation Considerations
       There some minor functionality issues to be aware of when comparing
       Perl for Unix (Perl/UX) to Perl/iX:

          MPE gcc/ld(1,8) doesn't properly support linking NMPRG executables
           against NMXL dynamic libraries, so you must manually run
           mpeix/relink after each re-build of Perl.

          Perl/iX File::Copy will use MPE's /bin/cp command to copy files by
           name in(1,8) order to preserve file(1,n) attributes like file(1,n) code.

          MPE (and thus Perl/iX) lacks support for setgrent(), endgrent(),
           setpwent(), endpwent().

          MPE (and thus Perl/iX) lacks support for hard links.

          MPE requires GETPRIVMODE() in(1,8) order to bind(2,n,1 builtins)() to ports less(1,3) than
           1024.  Perl/iX will call GETPRIVMODE() automatically on your behalf
           if(3,n) you attempt to bind(2,n,1 builtins)() to these low-numbered ports.  Note that
           the Perl/iX executable and the PERL account do not normally have
           CAP=PM, so if(3,n) you will be bind(2,n,1 builtins)()-ing to these privileged ports, you
           will manually need to add PM capability as appropriate.

          MPE requires that you bind(2,n,1 builtins)() to an IP address of zero.  Perl/iX
           automatically replaces the IP address that you pass to bind(2,n,1 builtins)() with
           a zero.

          MPE requires GETPRIVMODE() in(1,8) order to setuid().  There are too
           many calls to setuid() within Perl/iX, so I have not attempted an
           automatic GETPRIVMODE() solution similar to bind(2,n,1 builtins)().

Known Perl/iX Bugs Under Investigation
       None.

Perl/iX To-Do List
          Make setuid()/setgid() support work.

          Make sure that fcntl() against a socket(2,7,n) descriptor is redirected to
           sfcntl().

          Add support for Berkeley DB once I've finished porting Berkeley DB.

          Write an MPE XS extension library containing miscellaneous impor-
           tant MPE functions like GETPRIVMODE(), GETUSERMODE(), and sfcntl().

Perl/iX Change History
       May 6, 1999

          Patch LBCJXT6A is required on MPE/iX 5.5 machines in(1,8) order to pre-
           vent Perl/iX from dying with an unresolved external reference to
           _getenv_libc.

       April 7, 1999

          Updated to version(1,3,5) 5.005_03.

          The official source distribution once again compiles "straight out
           of the box" for MPE.

          The current incarnation of the 5.5 POSIX filename extended charac-
           ters patch is now MPEKX40B.

          The LIBSHP3K *.a -> *.sl library conversion script is now included
           as /PERL/PUB/LIBSHP3K.

       November 20, 1998

          Updated to version(1,3,5) 5.005_02.

          Fixed a DynaLoader bug that was unable to load(7,n) symbols from rela-
           tive path name libraries.

          Fixed a .xs compilation bug where the mpeixish.sh include file(1,n)
           wasn't being installed into the proper directory.

          All bugfixes will be submitted back to the official Perl develop-
           ers.

          The current incarnation of the POSIX filename extended characters
           patch is now MPEKXJ3A.

       August 14, 1998

          The previous POSIX filename extended characters patch MPEKX44C has
           been superseded by MPEKXB5A.

       August 7, 1998

          The previous POSIX filename extended characters patch MPEKX76A has
           been superseded by MPEKX44C.

       July 28, 1998

          Updated to version(1,3,5) 5.005_01.

       July 23, 1998

          Updated to version(1,3,5) 5.005 (production release).  The public freeware
           sources are now 100% MPE-ready "straight out of the box".

       July 17, 1998

          Updated to version(1,3,5) 5.005b1 (public beta release).  The public free-
           ware sources are now 99.9% MPE-ready.  By installing and testing
           this beta on your own HP3000, you will be helping to insure that
           the final release of 5.005 will be 100% MPE-ready and 100% bug
           free.

          My MPE binary release is now extracted using my standard INSTALL
           script.

       July 15, 1998

          Changed startperl to #!/PERL/PUB/perl so that Perl will recognize
           scripts more easily and efficiently.

       July 8, 1998

          Updated to version(1,3,5) 5.004_70 (internal developer release) which is
           now MPE-ready.  The next public freeware release of Perl should
           compile "straight out of the box" on MPE.  Note that this version(1,3,5)
           of Perl/iX was strictly internal to me and never publicly released.
           Note that [21]BIND/iX is now required (well, the include files and
           libbind.a) if(3,n) you wish to compile Perl/iX.

       November 6, 1997

          Updated to version(1,3,5) 5.004_04.  No changes in(1,8) MPE-specific function-
           ality.

       October 16, 1997

          Added Demos section to the Perl/iX home page so you can see some
           sample Perl applications running on my 3000.

       October 3, 1997

          Added System Requirements section to the Perl/iX home page just so
           the prerequisites stand out more. Various other home page tweaks.

       October 2, 1997

          Initial public release.

       September 1997

          Porting begins.
