24 The simplest way to obtain Perl for the MPE/iX is to go either of
25 these URLs and follow the instructions within.

33 =head1 What's New in Perl for MPE/iX
41 Updated for perl-5.8.8 and perl-5.9.3 by Ken Hirsch.
43 Simplified the build process by using the MPEAUTOCONF
44 functionality in Mark Klein's ld.
46 If you build this from scratch, make sure you have a version
47 of ld which supports it. In the shell, type
50 and look for AUTOCONF or MPEAUTOCONF near the bottom
53 ld --help 2>&1 | grep AUTOCONF
55 If you see don't see AUTOCONF or MPEAUTOCONF, make sure you get a new
58 You also do not have to use mpeix/relink after building, so the
59 recommend sequence is:
63 # or ./Configure -de -Dusedevel
64 # if you're building a development version
68 # if you run this in a job, do "make test_notty"
72 Be prepared for a wait. These take much longer on MPE/iX than on a Unix
73 system, because of a slow forking, mostly. On a lightly-loaded HP3000
74 Series 979 running MPE/iX 7.5:
77 make: 1 hour 15 minutes
78 make test 1 hour 45 minutes
80 Various socket problems were fixed in mpeix.c.
82 Mark Klein provided a fixed sigsetjmp (that works with dynamic
83 libraries) in mpeix_setjmp.c
93 Rebuilt to be compatible with mod_perl. If you plan on using
94 mod_perl, you MUST download and install this version of Perl/iX!
98 uselargefiles="undef": not available in MPE for POSIX files yet.
102 Now bundled with various add-on packages:
108 libnet (as seen on CPAN)
112 libwww-perl (LWP) which lets Perl programs behave like web browsers:
116 3. $doc = get('http://www.bixby.org/mark/perlix.html'); # reads the
117 web page into variable $doc
119 (http://www.bixby.org/mark/perlix.html)
123 mod_perl (just the perl portion; the actual DSO will be released
124 soon with Apache/iX 1.3.12 from bixby.org). This module allows you to
125 write high performance persistent Perl CGI scripts and all sorts of
126 cool things. (http://perl.apache.org/)
128 and much much more hiding under /PERL/PUB/.cpan/
132 The CPAN module now works for automatic downloading and
133 installing of add-on packages:
135 1. export FTP_PASSIVE=1
136 2. perl -MCPAN -e shell
137 3. Ignore any terminal I/O related complaints!
139 (http://theoryx5.uwinnipeg.ca/CPAN/data/perl/CPAN.html)
151 Updated to version 5.6.0. Builds straight out of the box on MPE/iX.
155 Perl's getpwnam() function which had regressed to being
156 unimplemented on MPE is now implemented once again.
166 Migrated from cccd.edu to bixby.org.
170 =head1 Welcome to Perl/iX
172 This is the official home page for the HP e3000 MPE/iX
173 ( http://www.hp.com/go/e3000 ) port of the Perl scripting
174 language ( http://www.perl.com/ ) which gives you all of the power of C,
175 awk, sed, and sh in a single language. Check here for the latest news,
176 implemented functionality, known bugs, to-do list, etc. Status reports
177 about major milestones will also be posted to the HP3000-L mailing list
178 ( http://www.lsoft.com/scripts/wl.exe?SL1=HP3000-L&H=RAVEN.UTC.EDU ) and
179 its associated gatewayed newsgroup comp.sys.hp.mpe.
181 I'm doing this port because I can't live without Perl on the Unix
182 machines that I administer, and I want to have the same power
183 available to me on MPE.
185 Please send your comments, questions, and bug reports directly to me,
186 Mark Bixby ( http://www.bixby.org/mark/ ). Or just post them to HP3000-L.
188 The platform I'm using to do this port is an HP 3000 957RX running
189 MPE/iX 6.0 and using the GNU gcc C compiler
190 ( http://jazz.external.hp.com/src/gnu/gnuframe.html ).
192 The combined porting wisdom from all of my ports can be found in my
193 MPE/iX Porting Guide (http://www.bixby.org/mark/porting.html).
195 IMPORTANT NOTICE: Yes, I do work for the HP CSY R&D lab, but ALL of
196 the software you download from bixby.org is my personal freeware that
197 is NOT supported by HP.
199 =head1 System Requirements for Perl/iX
205 MPE/iX 5.5 or later. This version of Perl/iX does NOT run on
206 MPE/iX 5.0 or earlier, nor does it run on "classic" MPE/V machines.
210 If you wish to recompile Perl, you must install both GNUCORE and
211 GNUGCC from jazz (http://jazz.external.hp.com/src/gnu/gnuframe.html).
215 Perl/iX will be happier on MPE/iX 5.5 if you install the MPEKX40B
216 extended POSIX filename characters patch, but this is optional.
220 Patch LBCJXT6A is required on MPE/iX 5.5 machines in order to
221 prevent Perl/iX from dying with an unresolved external reference
226 If you will be compiling Perl/iX yourself, you will also need
227 Syslog/iX ( http://www.bixby.org/mark/syslogix.html ) and the
228 /BIND/PUB/include and /BIND/PUB/lib portions of BIND/iX
229 ( http://www.bixby.org/mark/bindix.html ).
233 =head1 How to Obtain Perl/iX
239 Download Perl using either FTP.ARPA.SYS or some other client
243 Extract the installation script
247 Edit the installation script
251 Run the installation script
255 Convert your *.a system archive libraries to *.sl shared libraries
259 Download Perl using FTP.ARPA.SYS from your HP 3000 (the preferred
269 get perl-5.6.0-mpe.tar.Z /tmp/perl.tar.Z;disc=2147483647
272 .....Or download using some other generic web or ftp client (the alternate
275 Download the following files (make sure that you use "binary mode" or
276 whatever client feature that is 8-bit clean):
284 http://www.bixby.org/ftp/pub/mpe/perl-5.6.0-mpe.tar.Z
288 ftp://ftp.bixby.org/pub/mpe/perl-5.6.0-mpe.tar.Z
292 Upload those files to your HP 3000 in an 8-bit clean bytestream manner to:
298 Then extract the installation script (after both download methods)
301 :XEQ TAR.HPBIN.SYS 'xvfopz /tmp/perl.tar.Z INSTALL'
305 Edit the installation script
307 Examine the accounting structure creation commands and modify if
308 necessary (adding additional capabilities, choosing a non-system
311 :XEQ VI.HPBIN.SYS /tmp/INSTALL
315 Run the installation script.
317 The accounting structure will be created and then all files will be
318 extracted from the archive.
320 :XEQ SH.HPBIN.SYS /tmp/INSTALL
324 Convert your *.a system archive libraries to *.sl shared libraries
326 You only have to do this ONCE on your MPE/iX 5.5 machine in order to
327 convert /lib/lib*.a and /usr/lib/lib*.a libraries to their *.sl
328 equivalents. This step should not be necessary on MPE/iX 6.0 or later
329 machines because the 6.0 or later update process does it for you.

378 =head1 How to Compile Perl/iX
384 cd src/perl-5.6.0-mpe
388 Read the INSTALL file for the official instructions
404 make test (expect approximately 15 out of 11306 subtests to fail,
405 mostly due to MPE not supporting hard links, UDP socket problems,
406 and handling exit() return codes improperly)
414 Optionally create symbolic links that point to the Perl
415 executable, i.e. ln -s /PERL/PUB/PERL /usr/local/bin/perl

433 =head1 Getting Started with Perl/iX
435 Create your Perl script files with "#!/PERL/PUB/perl" (or an
436 equivalent symbolic link) as the first line. Use the chmod command to
437 make sure that your script has execute permission. Run your script!
439 Be sure to take a look at the CPAN module list
440 ( http://www.cpan.org/CPAN.html ). A wide variety of free Perl software
441 is available. You can automatically download these packages by using
442 the CPAN module ( http://theoryx5.uwinnipeg.ca/CPAN/data/perl/CPAN.html ).
444 =head1 MPE/iX Implementation Considerations
446 There some minor functionality issues to be aware of when comparing
447 Perl for Unix (Perl/UX) to Perl/iX:
453 MPE gcc/ld doesn't properly support linking NMPRG executables against
454 NMXL dynamic libraries, so you must manually run mpeix/relink after
455 each re-build of Perl.
459 Perl/iX File::Copy will use MPE's /bin/cp command to copy files by
460 name in order to preserve file attributes like file code.
464 MPE (and thus Perl/iX) lacks support for setgrent(), endgrent(),
465 setpwent(), endpwent().
469 MPE (and thus Perl/iX) lacks support for hard links.
473 MPE requires GETPRIVMODE() in order to bind() to ports less than 1024.
474 Perl/iX will call GETPRIVMODE() automatically on your behalf if you
475 attempt to bind() to these low-numbered ports. Note that the Perl/iX
476 executable and the PERL account do not normally have CAP=PM, so if you
477 will be bind()-ing to these privileged ports, you will manually need
478 to add PM capability as appropriate.
482 MPE requires that you bind() to an IP address of zero. Perl/iX
483 automatically replaces the IP address that you pass to bind() with
488 MPE requires GETPRIVMODE() in order to setuid(). There are too many
489 calls to setuid() within Perl/iX, so I have not attempted an automatic
490 GETPRIVMODE() solution similar to bind().
494 =head1 Known Perl/iX Bugs Under Investigation
498 =head1 Perl/iX To-Do List
504 Make setuid()/setgid() support work.
508 Make sure that fcntl() against a socket descriptor is redirected to sfcntl().
512 Add support for Berkeley DB once I've finished porting Berkeley DB.
516 Write an MPE XS extension library containing miscellaneous important
517 MPE functions like GETPRIVMODE(), GETUSERMODE(), and sfcntl().
521 =head1 Perl/iX Change History
529 Patch LBCJXT6A is required on MPE/iX 5.5 machines in order to prevent
530 Perl/iX from dying with an unresolved external reference to _getenv_libc.
540 Updated to version 5.005_03.
544 The official source distribution once again compiles "straight out
549 The current incarnation of the 5.5 POSIX filename extended
550 characters patch is now MPEKX40B.
554 The LIBSHP3K *.a -> *.sl library conversion script is now included
555 as /PERL/PUB/LIBSHP3K.
565 Updated to version 5.005_02.
569 Fixed a DynaLoader bug that was unable to load symbols from relative
574 Fixed a .xs compilation bug where the mpeixish.sh include file wasn't
575 being installed into the proper directory.
579 All bugfixes will be submitted back to the official Perl developers.
583 The current incarnation of the POSIX filename extended characters
584 patch is now MPEKXJ3A.
594 The previous POSIX filename extended characters patch MPEKX44C has
595 been superseded by MPEKXB5A.
605 The previous POSIX filename extended characters patch MPEKX76A has
606 been superseded by MPEKX44C.
616 Updated to version 5.005_01.
626 Updated to version 5.005 (production release). The public
627 freeware sources are now 100% MPE-ready "straight out of the box".
637 Updated to version 5.005b1 (public beta release). The public
638 freeware sources are now 99.9% MPE-ready. By installing and
639 testing this beta on your own HP3000, you will be helping to
640 insure that the final release of 5.005 will be 100% MPE-ready and
645 My MPE binary release is now extracted using my standard INSTALL script.
655 Changed startperl to #!/PERL/PUB/perl so that Perl will recognize
656 scripts more easily and efficiently.
666 Updated to version 5.004_70 (internal developer release) which is now
667 MPE-ready. The next public freeware release of Perl should compile
668 "straight out of the box" on MPE. Note that this version of Perl/iX
669 was strictly internal to me and never publicly released. Note that
670 [21]BIND/iX is now required (well, the include files and libbind.a) if
671 you wish to compile Perl/iX.
681 Updated to version 5.004_04. No changes in MPE-specific functionality.
691 Added Demos section to the Perl/iX home page so you can see some
692 sample Perl applications running on my 3000.
702 Added System Requirements section to the Perl/iX home page just so the
703 prerequisites stand out more. Various other home page tweaks.
713 Initial public release.
