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 Perl for MPE/iX
January 12, 2006
o 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 build-
ing, 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 fork-
ing, 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
o June 1, 2000
o Rebuilt to be compatible with mod_perl. If you
plan on using mod_perl, you MUST download and
install this version of Perl/iX!
o uselargefiles="undef": not available in MPE for
POSIX files yet.
o Now bundled with various add-on packages:
o libnet (as seen on CPAN)
o 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)
o 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 perfor-
mance persistent Perl CGI scripts and all
sorts of cool things.
(http://perl.apache.org/)
and much much more hiding under
/PERL/PUB/.cpan/
o The CPAN module now works for automatic
downloading and installing of add-on pack-
ages:
1. export FTP_PASSIVE=1
2. perl -MCPAN -e shell
3. Ignore any terminal I/O related complaints!
(http://theoryx5.uwin-
nipeg.ca/CPAN/data/perl/CPAN.html)
May 20, 2000
o Updated to version 5.6.0. Builds straight out of
the box on MPE/iX.
o Perl's getpwnam() function which had regressed to
being unimplemented on MPE is now implemented once
again.
September 17, 1999
o 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
) 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
o 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.
o 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).
o Perl/iX will be happier on MPE/iX 5.5 if you install
the MPEKX40B extended POSIX filename characters patch,
but this is optional.
o 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.
o If you will be compiling Perl/iX yourself, you will
also need Syslog/iX ( http://www.bixby.org/mark/sys-
logix.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):
o 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
o Upload those files to your HP 3000 in an 8-bit
clean bytestream manner to:
/tmp/perl.tar.Z
o Then extract the installation script (after both
download methods)
:CHDIR /tmp
:XEQ TAR.HPBIN.SYS 'xvfopz /tmp/perl.tar.Z INSTALL'
o Edit the installation script
Examine the accounting structure creation commands
and modify if necessary (adding additional capa-
bilities, choosing a non-system volume set, etc).
:XEQ VI.HPBIN.SYS /tmp/INSTALL
o 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
o 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 equiva-
lents. 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 sub-
tests 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

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 down-
load these packages by using the CPAN module ( http://the-
oryx5.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:
o MPE gcc/ld doesn't properly support linking NMPRG exe-
cutables against NMXL dynamic libraries, so you must
manually run mpeix/relink after each re-build of Perl.
o 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.
o MPE (and thus Perl/iX) lacks support for setgrent(),
endgrent(), setpwent(), endpwent().
o MPE (and thus Perl/iX) lacks support for hard links.
o MPE requires GETPRIVMODE() in order to bind() to ports
less than 1024. Perl/iX will call GETPRIVMODE() auto-
matically on your behalf if you attempt to bind() to
these low-numbered ports. Note that the Perl/iX exe-
cutable and the PERL account do not normally have
CAP=PM, so if you will be bind()-ing to these privi-
leged ports, you will manually need to add PM capabil-
ity as appropriate.
o 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.
o 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
o Make setuid()/setgid() support work.
o Make sure that fcntl() against a socket descriptor is
redirected to sfcntl().
o Add support for Berkeley DB once I've finished porting
Berkeley DB.
o Write an MPE XS extension library containing miscella-
neous important MPE functions like GETPRIVMODE(),
GETUSERMODE(), and sfcntl().
Perl/iX Change History
May 6, 1999
o 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
o Updated to version 5.005_03.
o The official source distribution once again com-
piles "straight out of the box" for MPE.
o The current incarnation of the 5.5 POSIX filename
extended characters patch is now MPEKX40B.
o The LIBSHP3K *.a -> *.sl library conversion script
is now included as /PERL/PUB/LIBSHP3K.
November 20, 1998
o Updated to version 5.005_02.
o Fixed a DynaLoader bug that was unable to load
symbols from relative path name libraries.
o Fixed a .xs compilation bug where the mpeixish.sh
include file wasn't being installed into the
proper directory.
o All bugfixes will be submitted back to the offi-
cial Perl developers.
o The current incarnation of the POSIX filename
extended characters patch is now MPEKXJ3A.
August 14, 1998
o The previous POSIX filename extended characters
patch MPEKX44C has been superseded by MPEKXB5A.
August 7, 1998
o The previous POSIX filename extended characters
patch MPEKX76A has been superseded by MPEKX44C.
July 28, 1998
o Updated to version 5.005_01.
July 23, 1998
o Updated to version 5.005 (production release).
The public freeware sources are now 100% MPE-ready
"straight out of the box".
July 17, 1998
o 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.
o My MPE binary release is now extracted using my
standard INSTALL script.
July 15, 1998
o Changed startperl to #!/PERL/PUB/perl so that Perl
will recognize scripts more easily and effi-
ciently.
July 8, 1998
o 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 pub-
licly 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
o Updated to version 5.004_04. No changes in MPE-
specific functionality.
October 16, 1997
o Added Demos section to the Perl/iX home page so
you can see some sample Perl applications running
on my 3000.
October 3, 1997
o 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
o Initial public release.
September 1997
o Porting begins.
