- Change History
- 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!
- bincompat5005="undef": sorry, but you will have to recompile any binary
5.005 extensions that you may be using (if any; there is no 5.005 code
in what you download from bixby.org)
- uselargefiles="undef": not available in MPE for POSIX files yet.
- Now bundled with various add-on packages:
- libnet
- libwww-perl
(LWP) which lets Perl programs behave like web browsers:
- #!/PERL/PUB/perl
- use LWP::Simple;
- $doc = get('//bixby.org/mark/perlix.html'); # reads the
web page into variable $doc
- 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.
- and much much more hiding under /PERL/PUB/.cpan/
- The
CPAN module now works for automatic downloading and installing of add-on
packages:
- export FTP_PASSIVE=1
- perl -MCPAN -e shell
- 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.
This is the official home page for the HP e3000 MPE/iX port of the Perl
scripting language 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 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, by e-mailing to mark@bixby.org.
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.
The combined porting wisdom from all of my ports can be found in my
MPE/iX Porting Guide.
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.
- 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.
- 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
and the /BIND/PUB/include and /BIND/PUB/lib portions of BIND/iX.
- Download Perl using either FTP.ARPA.SYS or some other client
- Extract the installation script
- Edit the installation script
- Run the installation script
- 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):
Upload those files to your HP 3000 in an 8-bit clean bytestream manner
to:
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

- The file you're reading now.
- INSTALL
- Perl/iX Installation script.
- LIBSHP3K
- Script to convert *.a system archive libraries to *.sl shared libraries.
- PERL
- Perl NMPRG executable. A version-numbered backup copy also exists.
You might wish to "ln -s /PERL/PUB/PERL /usr/local/bin/perl".
- .cpan/
- Much add-on source code downloaded with the CPAN module.
- lib/
- Perl libraries, both core and add-on.

- Perl man page documentation.
- public_html/feedback.cgi
- Sample feedback CGI form written in Perl.
- src/perl-5.6.0-mpe
- Source code.
- cd src/perl-5.6.0-mpe
- Read the INSTALL file for the official instructions
- ./Configure -d
- make
- ./mpeix/relink
- 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)
- make install
- 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

15 tests and 94 subtests skipped.
Failed 7/236 test scripts, 97.03% okay. 15/11306 subtests failed, 99.87% okay.
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. A wide variety of free Perl software is available.
You can automatically download these packages by using the
CPAN module.
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.
- If you use Perl/iX fcntl() against a socket it will fail, because MPE requires
that you use sfcntl() instead. Perl/iX does not presently support
sfcntl().
- 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().
- 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().
- May 6, 1999
- 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.
- 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 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 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
- September 1997
