| 28 | Rebuilt to be compatible with mod_perl. If you plan on using |
| 29 | mod_perl, you MUST download and install this version of Perl/iX! |
| 30 | |
| 31 | =item * |
| 32 | |
| 33 | bincompat5005="undef": sorry, but you will have to recompile any |
| 34 | binary 5.005 extensions that you may be using (if any; there is no |
| 35 | 5.005 code in what you download from bixby.org) |
| 36 | uselargefiles="undef": not available in MPE for POSIX files yet. |
| 37 | |
| 38 | =item * |

| 40 | Now bundled with various add-on packages: |

| 50 | libwww-perl (LWP) which lets Perl programs behave like web browsers: |
| 51 | |
| 52 | 1. #!/PERL/PUB/perl |
| 53 | 2. use LWP::Simple; |
| 54 | 3. $doc = get('http://www.bixby.org/mark/perlix.html'); # reads the |

| 58 | |
| 59 | =item * |
| 60 | |
| 61 | mod_perl (just the perl portion; the actual DSO will be released |
| 62 | soon with Apache/iX 1.3.12 from bixby.org). This module allows you to |
| 63 | write high performance persistent Perl CGI scripts and all sorts of |
| 64 | cool things. (http://perl.apache.org/) |
| 65 | |
| 66 | and much much more hiding under /PERL/PUB/.cpan/ |
| 67 | |
| 68 | =item * |
| 69 | |
| 70 | The CPAN module now works for automatic downloading and |
| 71 | installing of add-on packages: |
| 72 | |
| 73 | 1. export FTP_PASSIVE=1 |
| 74 | 2. perl -MCPAN -e shell |
| 75 | 3. Ignore any terminal I/O related complaints! |

| 89 | Updated to version 5.6.0. Builds straight out of the box on MPE/iX. |
| 90 | |
| 91 | =item * |
| 92 | |
| 93 | Perl's getpwnam() function which had regressed to being |

| 107 | |
| 108 | =head1 Welcome to Perl/iX |
| 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. |

| 143 | |
| 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 |
| 150 | GNUGCC from jazz (http://jazz.external.hp.com/src/gnu/gnuframe.html). |
| 151 | |
| 152 | =item * |
| 153 | |
| 154 | Perl/iX will be happier on MPE/iX 5.5 if you install the MPEKX40B |
| 155 | extended POSIX filename characters patch, but this is optional. |
| 156 | |
| 157 | =item * |
| 158 | |
| 159 | Patch LBCJXT6A is required on MPE/iX 5.5 machines in order to |
| 160 | prevent Perl/iX from dying with an unresolved external reference |
| 161 | to _getenv_libc. |
| 162 | |
| 163 | =item * |
| 164 | |
| 165 | If you will be compiling Perl/iX yourself, you will also need |
| 166 | Syslog/iX (http://www.bixby.org/mark/syslogix.html) and the |
| 167 | /BIND/PUB/include and /BIND/PUB/lib portions of BIND/iX |
| 168 | (http://www.bixby.org/mark/bindix.html). |

| 210 | |
| 211 | .....Or download using some other generic web or ftp client (the alternate |

| 234 | |
| 235 | =item * |

| 249 | |
| 250 | :XEQ VI.HPBIN.SYS /tmp/INSTALL |
| 251 | |
| 252 | =item * |
| 253 | |

| 371 | |
| 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(). |
| 436 | |

| 448 | |
| 449 | Make setuid()/setgid() support work. |
| 450 | |
| 451 | =item * |
| 452 | |
| 453 | Make sure that fcntl() against a socket descriptor is redirected to sfcntl(). |
| 454 | |
| 455 | =item * |
| 456 | |
| 457 | Add support for Berkeley DB once I've finished porting Berkeley DB. |

| 459 | =item * |
| 460 | |

| 585 | insure that the final release of 5.005 will be 100% MPE-ready and |

| 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. |
