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.

Whats New in Perl for MPE/iX
       January 12, 2006

	  Updated for perl-5.8.8 and perl-5.9.3 by Ken Hirsch.

	   Simplified the build process by using the MPEAUTOCONF functionality
	   in Mark Kleins ld.

	   If you build this from scratch, make sure you have a version of ld
	   which supports it.  In the shell, type

	     ld --help
	       and look for AUTOCONF or MPEAUTOCONF near the bottom

	     or do this:
	     ld --help 2>&1 | grep AUTOCONF

	   If you see dont see AUTOCONF or MPEAUTOCONF, make sure you get a
	   new version.

	   You also do not have to use mpeix/relink after building, so the
	   recommend sequence is:

	     ./Configure -de

		 # or ./Configure -de -Dusedevel
		 # if youre building a development version

	     make
	     make test
		# if you run this in a job, do "make test_notty"

	     make install

	   Be prepared for a wait. These take much longer on MPE/iX than on a
	   Unix system, because of a slow forking, mostly.  On a lightly-
	   loaded HP3000 Series 979 running MPE/iX 7.5:

	       Configure: 1 hour
	       make:	  1 hour 15 minutes
	       make test  1 hour 45 minutes

	   Various socket problems were fixed in mpeix.c.

	   Mark Klein provided a fixed sigsetjmp (that works with dynamic
	   libraries) in mpeix_setjmp.c

	  June 1, 2000

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

	      uselargefiles="undef": not available in 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 high performance per
		       sistent 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 5.6.0.  Builds straight out of the box on
	       MPE/iX.

	      Perls getpwnam() function which had regressed to being unim
	       plemented 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 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.

       Im doing this port because I cant 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 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 Im 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 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 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 you install the MPEKX40B
	   extended POSIX filename characters patch, but this is optional.

	  Patch LBCJXT6A is required on MPE/iX 5.5 machines in 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 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

	   .....Or download using some other generic web or ftp client (the
	   alternate 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 an 8-bit clean bytestream
	       manner to:

		   /tmp/perl.tar.Z

	      Then extract the installation script (after both download meth
	       ods)

		   :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 necessary (adding additional capabilities, choosing a non-
	       system volume set, 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
	       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
	       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 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 problems,
	   and handling exit() 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

	   The summary test results from "cd t; ./perl -I../lib harness":

	     Failed Test  Status Wstat Total Fail  Failed  List of failed
	     ---------------------------------------------------------------------------
	     io/fs.t			  29	8  27.59%  2-5, 7-9, 11

	     op/lex_assign.t		 187	1   0.53%  13
	     op/stat.t			  58	1   1.72%  3
	     15 tests and 94 subtests skipped.
	     Failed 7/236 test scripts, 97.03% okay. 15/11306 subtests failed, 99.87% okay.

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

       Be sure to take a look 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 doesnt 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 MPEs /bin/cp command to copy files by
	   name in order to preserve file attributes like file 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 order to bind() to ports less than
	   1024.  Perl/iX will call GETPRIVMODE() automatically on your behalf
	   if you attempt to bind() to these low-numbered ports.  Note that
	   the Perl/iX executable and the PERL account do not normally have
	   CAP=PM, so if you will be bind()-ing to these privileged ports, you
	   will manually need to add PM capability as appropriate.

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

	  MPE requires GETPRIVMODE() in 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().

Known Perl/iX Bugs Under Investigation
       None.

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

	  Make sure that fcntl() against a socket descriptor is redirected to
	   sfcntl().

	  Add support for Berkeley DB once Ive 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 order to pre
	   vent Perl/iX from dying with an unresolved external reference to
	   _getenv_libc.

	   April 7, 1999

	      Updated to version 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
	       characters patch is now MPEKX40B.

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

	   November 20, 1998

	      Updated to version 5.005_02.

	      Fixed a DynaLoader bug that was unable to load symbols from
	       relative path name libraries.

	      Fixed a .xs compilation bug where the mpeixish.sh include file
	       wasnt being installed into the proper directory.

	      All bugfixes will be submitted back to the official Perl devel
	       opers.

	      The current incarnation of the POSIX filename extended charac
	       ters 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 5.005_01.

	   July 23, 1998

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

	   July 17, 1998

	      Updated to version 5.005b1 (public beta release).  The public
	       freeware 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 recog
	       nize scripts more easily and efficiently.

	   July 8, 1998

	      Updated to version 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 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 you wish to compile
	       Perl/iX.

	   November 6, 1997

	      Updated to version 5.004_04.  No changes in MPE-specific func
	       tionality.

	   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.
