108 | =head1 Welcome | |
109 | ||
110 | This is the official home page for the HP e3000 MPE/iX | |
111 | (http://www.businessservers.hp.com/) port of the Perl scripting | |
112 | language (http://www.perl.com/) which gives you all of the power of C, | |
113 | awk, sed, and sh in a single language. Check here for the latest news, | |
114 | implemented functionality, known bugs, to-do list, etc. Status reports | |
115 | about major milestones will also be posted to the HP3000-L mailing list | |
116 | (http://www.lsoft.com/scripts/wl.exe?SL1=HP3000-L&H=RAVEN.UTC.EDU) and | |
117 | its associated gatewayed newsgroup comp.sys.hp.mpe. | |
118 | ||
119 | I'm doing this port because I can't live without Perl on the Unix | |
120 | machines that I administer, and I want to have the same power | |
121 | available to me on MPE. | |
122 | ||
123 | Please send your comments, questions, and bug reports directly to me, | |
124 | Mark Bixby (http://www.bixby.org/mark/), by e-mailing to | |
125 | mark@bixby.org. Or just post them to HP3000-L. | |
126 | ||
127 | The platform I'm using to do this port is an HP 3000 957RX running | |
128 | MPE/iX 6.0 and using the GNU gcc C compiler | |
129 | (http://jazz.external.hp.com/src/gnu/gnuframe.html). | |
130 | ||
131 | The combined porting wisdom from all of my ports can be found in my | |
132 | MPE/iX Porting Guide (http://www.bixby.org/mark/porting.html). | |
133 | ||
134 | IMPORTANT NOTICE: Yes, I do work for the HP CSY R&D lab, but ALL of | |
135 | the software you download from bixby.org is my personal freeware that | |
136 | is NOT supported by HP. | |

144 | MPE/iX 5.5 or later. This version of Perl/iX does NOT run on | |
145 | MPE/iX 5.0 or earlier, nor does it run on "classic" MPE/V machines. | |
146 | ||
147 | =item * | |
148 | ||
149 | If you wish to recompile Perl, you must install both GNUCORE and | |

151 | ||

154 | Perl/iX will be happier on MPE/iX 5.5 if you install the MPEKX40B | |

167 | /BIND/PUB/include and /BIND/PUB/lib portions of BIND/iX | |

372 | =head1 Getting Started with Perl/iX | |
373 | ||
374 | Create your Perl script files with "#!/PERL/PUB/perl" (or an | |
375 | equivalent symbolic link) as the first line. Use the chmod command to | |
376 | make sure that your script has execute permission. Run your script! | |
377 | ||
378 | Be sure to take a look at the CPAN module list | |
379 | (http://www.cpan.org/CPAN.html). A wide variety of free Perl software | |
380 | is available. You can automatically download these packages by using | |
381 | the CPAN module (http://theoryx5.uwinnipeg.ca/CPAN/data/perl/CPAN.html). | |
382 | ||
383 | =head1 MPE/iX Implementation Considerations | |
384 | ||
385 | There some minor functionality issues to be aware of when comparing | |
386 | Perl for Unix (Perl/UX) to Perl/iX: | |
387 | ||
388 | =over 4 | |
389 | ||
390 | =item * | |
391 | ||
392 | MPE gcc/ld doesn't properly support linking NMPRG executables against | |
393 | NMXL dynamic libraries, so you must manually run mpeix/relink after | |
394 | each re-build of Perl. | |
395 | ||
396 | =item * | |
397 | ||
398 | Perl/iX File::Copy will use MPE's /bin/cp command to copy files by | |
399 | name in order to preserve file attributes like file code. | |
400 | ||
401 | =item * | |
402 | ||
403 | MPE (and thus Perl/iX) lacks support for setgrent(), endgrent(), | |
404 | setpwent(), endpwent(). | |
405 | ||
406 | =item * | |
407 | ||
408 | MPE (and thus Perl/iX) lacks support for hard links. | |
409 | ||
410 | =item * | |
411 | ||
412 | MPE requires GETPRIVMODE() in order to bind() to ports less than 1024. | |
413 | Perl/iX will call GETPRIVMODE() automatically on your behalf if you | |
414 | attempt to bind() to these low-numbered ports. Note that the Perl/iX | |
415 | executable and the PERL account do not normally have CAP=PM, so if you | |
416 | will be bind()-ing to these privileged ports, you will manually need | |
417 | to add PM capability as appropriate. | |
418 | ||
419 | =item * | |
420 | ||
421 | MPE requires that you bind() to an IP address of zero. Perl/iX | |
422 | automatically replaces the IP address that you pass to bind() with | |
423 | a zero. | |
424 | ||
425 | =item * | |
426 | ||
427 | If you use Perl/iX fcntl() against a socket it will fail, because MPE | |
428 | requires that you use sfcntl() instead. Perl/iX does not presently | |
429 | support sfcntl(). | |
430 | ||
431 | =item * | |
432 | ||
433 | MPE requires GETPRIVMODE() in order to setuid(). There are too many | |
434 | calls to setuid() within Perl/iX, so I have not attempted an automatic | |
435 | GETPRIVMODE() solution similar to bind(). | |

450 | ||

452 | ||
453 | Make sure that fcntl() against a socket descriptor is redirected to sfcntl(). | |

611 | Updated to version 5.004_70 (internal developer release) which is now | |
612 | MPE-ready. The next public freeware release of Perl should compile | |
613 | "straight out of the box" on MPE. Note that this version of Perl/iX | |
614 | was strictly internal to me and never publicly released. Note that | |
615 | [21]BIND/iX is now required (well, the include files and libbind.a) if | |
616 | you wish to compile Perl/iX. | |
