Perl language for MPE
Last updated January 12, 2006 @ 2100 UTC
NOTE
This is a podified version of what used to be on the above-mentioned web page, podified by Jarkko Hietaniemi 2001-Jan-01.What's 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 Klein's 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 don't 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 you're 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

- •
- 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:
-
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 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!
-
May 20, 2000
- Updated to version 5.6.0. Builds straight out of the box on MPE/iX.
- Perl's getpwnam() function which had regressed to being unimplemented 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, implemented 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 <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 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.external.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.external.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 prevent Perl/iX from dying with an unresolved external reference to _getenv_libc.
- If you will be compiling Perl/iX yourself, you will also need Syslog/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 [email protected] 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 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 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

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://search.cpan.org/dist/CPAN/> ).
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 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 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 I've finished porting Berkeley DB.
- Write an MPE XS extension library containing miscellaneous important MPE functions like GETPRIVMODE(), GETUSERMODE(), and sfcntl().
Perl/iX Change History

- 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 wasn't being installed into the proper directory.
- All bugfixes will be submitted back to the official Perl developers.
- 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 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 recognize 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 functionality.
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.
