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.

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":

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.
