README.mpeix - Perl/iX for HP e3000 MPE

http://www.bixby.org/mark/perlix.html http://jazz.external.hp.com/src/hp_freeware/perl/ Perl language for MPE Last updated January 12, 2006 @ 2100 UTC

This is a podified version of the above-mentioned web page, podified by Jarkko Hietaniemi 2001-Jan-01.

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

"" Updated for perl-5.8.8 and perl-5.9.3 by Ken Hirsch. Simplified the build process by using the \s-1MPEAUTOCONF\s0 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 \s-1AUTOCONF\s0 or \s-1MPEAUTOCONF\s0, 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 \s-1HP3000\s0 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 \s-1MUST\s0 download and install this version of Perl/iX!

"" uselargefiles=“undef”: not available in \s-1MPE\s0 for \s-1POSIX\s0 files yet.

"" Now bundled with various add-on packages:

"" libnet (as seen on \s-1CPAN\s0)

"" libwww-perl (\s-1LWP\s0) 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 \s-1DSO\s0 will be released soon with Apache/iX 1.3.12 from bixby.org). This module allows you to write high performance persistent Perl \s-1CGI\s0 scripts and all sorts of cool things. (http://perl.apache.org/) and much much more hiding under /PERL/PUB/.cpan/

"" The \s-1CPAN\s0 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)

"" 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 \s-1MPE\s0 is now implemented once again.

"" Migrated from cccd.edu to bixby.org.

This is the official home page for the \s-1HP\s0 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 \s-1HP3000-L\s0 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 \s-1MPE\s0. Please send your comments, questions, and bug reports directly to me, Mark Bixby ( http://www.bixby.org/mark/ ). Or just post them to \s-1HP3000-L\s0. The platform I'm using to do this port is an \s-1HP\s0 3000 957RX running MPE/iX 6.0 and using the \s-1GNU\s0 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). \s-1IMPORTANT\s0 \s-1NOTICE:\s0 Yes, I do work for the \s-1HP\s0 \s-1CSY\s0 R&D lab, but \s-1ALL\s0 of the software you download from bixby.org is my personal freeware that is \s-1NOT\s0 supported by \s-1HP\s0.

"" MPE/iX 5.5 or later. This version of Perl/iX does \s-1NOT\s0 run on MPE/iX 5.0 or earlier, nor does it run on “classic” \s-1MPE/V\s0 machines.

"" If you wish to recompile Perl, you must install both \s-1GNUCORE\s0 and \s-1GNUGCC\s0 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 \s-1MPEKX40B\s0 extended \s-1POSIX\s0 filename characters patch, but this is optional.

"" Patch \s-1LBCJXT6A\s0 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 ).

"1." Download Perl using either \s-1FTP\s0.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

"" 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 \s-1HP\s0 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 \s-1ONCE\s0 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

"\s-1README\s0" The file you're reading now.

"\s-1INSTALL\s0" Perl/iX Installation script.

"\s-1LIBSHP3K\s0" Script to convert *.a system archive libraries to *.sl shared libraries.

"\s-1PERL\s0" Perl \s-1NMPRG\s0 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 \s-1CPAN\s0 module.

"lib/" Perl libraries, both core and add-on.

"man/" Perl man page documentation.

"public_html/feedback.cgi" Sample feedback \s-1CGI\s0 form written in Perl.

"src/perl-5.6.0-mpe" Source code.

"1." cd src/perl-5.6.0-mpe

"2." Read the \s-1INSTALL\s0 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 \s-1MPE\s0 not supporting hard links, \s-1UDP\s0 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

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 \s-1CPAN\s0 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 \s-1CPAN\s0 module ( http://theoryx5.uwinnipeg.ca/CPAN/data/perl/CPAN.html ).

There some minor functionality issues to be aware of when comparing Perl for Unix (Perl/UX) to Perl/iX:

"" \s-1MPE\s0 gcc/ld doesn't properly support linking \s-1NMPRG\s0 executables against \s-1NMXL\s0 dynamic libraries, so you must manually run mpeix/relink after each re-build of Perl.

"" Perl/iX File::Copy will use \s-1MPE\s0's /bin/cp command to copy files by name in order to preserve file attributes like file code.

"" \s-1MPE\s0 (and thus Perl/iX) lacks support for setgrent(), endgrent(), setpwent(), endpwent().

"" \s-1MPE\s0 (and thus Perl/iX) lacks support for hard links.

"" \s-1MPE\s0 requires \s-1GETPRIVMODE\s0() in order to bind() to ports less than 1024. Perl/iX will call \s-1GETPRIVMODE\s0() automatically on your behalf if you attempt to bind() to these low-numbered ports. Note that the Perl/iX executable and the \s-1PERL\s0 account do not normally have CAP=PM, so if you will be bind()-ing to these privileged ports, you will manually need to add \s-1PM\s0 capability as appropriate.

"" \s-1MPE\s0 requires that you bind() to an \s-1IP\s0 address of zero. Perl/iX automatically replaces the \s-1IP\s0 address that you pass to bind() with a zero.

"" \s-1MPE\s0 requires \s-1GETPRIVMODE\s0() in order to setuid(). There are too many calls to setuid() within Perl/iX, so I have not attempted an automatic \s-1GETPRIVMODE\s0() solution similar to bind().

None.

"" Make setuid()/setgid() support work.

"" Make sure that fcntl() against a socket descriptor is redirected to sfcntl().

"" Add support for Berkeley \s-1DB\s0 once I've finished porting Berkeley \s-1DB\s0.

"" Write an \s-1MPE\s0 \s-1XS\s0 extension library containing miscellaneous important \s-1MPE\s0 functions like \s-1GETPRIVMODE\s0(), \s-1GETUSERMODE\s0(), and sfcntl().

"" Patch \s-1LBCJXT6A\s0 is required on MPE/iX 5.5 machines in order to prevent Perl/iX from dying with an unresolved external reference to _getenv_libc.

"" Updated to version 5.005_03.

"" The official source distribution once again compiles “straight out of the box” for \s-1MPE\s0.

"" The current incarnation of the 5.5 \s-1POSIX\s0 filename extended characters patch is now \s-1MPEKX40B\s0.

"" The \s-1LIBSHP3K\s0 *.a -> *.sl library conversion script is now included as /PERL/PUB/LIBSHP3K.

"" 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 \s-1POSIX\s0 filename extended characters patch is now \s-1MPEKXJ3A\s0.

"" The previous \s-1POSIX\s0 filename extended characters patch \s-1MPEKX44C\s0 has been superseded by \s-1MPEKXB5A\s0.

"" Updated to version 5.005 (production release). The public freeware sources are now 100% MPE-ready “straight out of the box”.

"" 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 \s-1HP3000\s0, you will be helping to insure that the final release of 5.005 will be 100% MPE-ready and 100% bug free.

"" My \s-1MPE\s0 binary release is now extracted using my standard \s-1INSTALL\s0 script.

"" Changed startperl to #!/PERL/PUB/perl so that Perl will recognize scripts more easily and efficiently.

"" 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 \s-1MPE\s0. 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.

"" Updated to version 5.004_04. No changes in MPE-specific functionality.

"" Added Demos section to the Perl/iX home page so you can see some sample Perl applications running on my 3000.

"" Added System Requirements section to the Perl/iX home page just so the prerequisites stand out more. Various other home page tweaks.

"" Initial public release.

"" Porting begins.
