15 | =head2 Using perl as shipped with HP-UX |
16 | ||
7cd31a2a MB |
17 | Application release September 2001, HP-UX 11.00 is the first to ship |
18 | with Perl. By the time it was perl-5.6.1 in /opt/perl. The first | |
19 | occurrence is on CD 5012-7954 and can be installed using | |
c3c48d5c | 20 | |
af8e01f2 | 21 | swinstall -s /cdrom perl |
c3c48d5c | 22 | |
34d14706 | 23 | assuming you have mounted that CD on /cdrom. |
c3c48d5c | 24 | |
c8fb9d34 MB |
25 | That build was a portable hppa-1.1 multithread build that supports large |
26 | files compiled with gcc-2.9-hppa-991112. | |
c3c48d5c | 27 | |
c8fb9d34 | 28 | If you perform a new installation, then (a newer) Perl will be installed |
34d14706 | 29 | automatically. Pre-installed HP-UX systems now have more recent versions |
c8fb9d34 | 30 | of Perl and the updated modules. |

32 | The official (threaded) builds from HP, as they are shipped on the |
33 | Application DVD/CD's are available on | |
635d4d9b | 34 | L<http://www.software.hp.com/portal/swdepot/displayProductInfo.do?productNumber=PERL> |
c8fb9d34 | 35 | for both PA-RISC and IPF (Itanium Processor Family). They are built |
ddce4f23 | 36 | with the HP ANSI-C compiler. Up till 5.8.8 that was done by ActiveState. |

61 | =head2 Using perl from HP's porting centre |
62 | ||
34d14706 MB |
63 | HP porting centre tries to keep up with customer demand and release |
64 | updates from the Open Source community. Having precompiled Perl binaries | |
65 | available is obvious, though "up-to-date" is something relative. At the | |
66 | moment of writing only perl-5.10.1 was available (with 5.16.3 being the | |
67 | latest stable release from the porters point of view). | |
48529397 MB |
68 | |
69 | The HP porting centres are limited in what systems they are allowed | |
70 | to port to and they usually choose the two most recent OS versions | |
34d14706 | 71 | available. |
48529397 MB |
72 | |
73 | HP has asked the porting centre to move Open Source binaries | |
74 | from /opt to /usr/local, so binaries produced since the start | |
75 | of July 2002 are located in /usr/local. | |
76 | ||
635d4d9b | 77 | One of HP porting centres URL's is L<http://hpux.connect.org.uk/> |
48529397 MB |
78 | The port currently available is built with GNU gcc. |

86 | =head2 Compiling Perl 5 on HP-UX |
87 | ||
60ed1d8c GS |
88 | When compiling Perl, you must use an ANSI C compiler. The C compiler |
89 | that ships with all HP-UX systems is a K&R compiler that should only be | |
90 | used to build new kernels. | |
f2a260d6 GS |
91 | |
92 | Perl can be compiled with either HP's ANSI C compiler or with gcc. The | |
60ed1d8c GS |
93 | former is recommended, as not only can it compile Perl with no |
94 | difficulty, but also can take advantage of features listed later that | |
95 | require the use of HP compiler-specific command-line flags. | |
f2a260d6 | 96 | |
60ed1d8c | 97 | If you decide to use gcc, make sure your installation is recent and |
b48c3bfb | 98 | complete, and be sure to read the Perl INSTALL file for more gcc-specific |
60ed1d8c | 99 | details. |

c8fb9d34 | 103 | HP's HP9000 Unix systems run on HP's own Precision Architecture |
60ed1d8c GS |
104 | (PA-RISC) chip. HP-UX used to run on the Motorola MC68000 family of |
105 | chips, but any machine with this chip in it is quite obsolete and this | |
106 | document will not attempt to address issues for compiling Perl on the | |
107 | Motorola chipset. | |

109 | The version of PA-RISC at the time of this document's last update is 2.0, |
110 | which is also the last there will be. HP PA-RISC systems are usually | |
1a43aa03 | 111 | referred to with model description "HP 9000". The last CPU in this series |

151 | =head2 Portability Between PA-RISC Versions | |
152 | ||
153 | An executable compiled on a PA-RISC 2.0 platform will not execute on a | |
154 | PA-RISC 1.1 platform, even if they are running the same version of | |
155 | HP-UX. If you are building Perl on a PA-RISC 2.0 platform and want that | |
156 | Perl to also run on a PA-RISC 1.1, the compiler flags +DAportable and | |
157 | +DS32 should be used. | |
158 | ||
159 | It is no longer possible to compile PA-RISC 1.0 executables on either | |
160 | the PA-RISC 1.1 or 2.0 platforms. The command-line flags are accepted, | |
161 | but the resulting executable will not run when transferred to a PA-RISC | |
162 | 1.0 system. | |

242 | the exception of a few differences detailed below and in later sections, |
243 | Perl should compile with no problems. | |
13e84f2c JH |
244 | |
245 | Although PA-RISC binaries can run on Itanium systems, you should not | |
246 | attempt to use a PA-RISC version of Perl on an Itanium system. This is | |
247 | because shared libraries created on an Itanium system cannot be loaded | |
248 | while running a PA-RISC executable. | |

288 | =head2 Building Dynamic Extensions on HP-UX |
289 | ||
290 | HP-UX supports dynamically loadable libraries (shared libraries). | |
13e84f2c JH |
291 | Shared libraries end with the suffix .sl. On Itanium systems, |
292 | they end with the suffix .so. | |
f2a260d6 | 293 | |
60ed1d8c GS |
294 | Shared libraries created on a platform using a particular PA-RISC |
295 | version are not usable on platforms using an earlier PA-RISC version by | |
296 | default. However, this backwards compatibility may be enabled using the | |
297 | same +DAportable compiler flag (with the same PA-RISC 1.0 caveat | |
298 | mentioned above). | |
f2a260d6 | 299 | |
13e84f2c JH |
300 | Shared libraries created on an Itanium platform cannot be loaded on |
301 | a PA-RISC platform. Shared libraries created on a PA-RISC platform | |
302 | can only be loaded on an Itanium platform if it is a PA-RISC executable | |
303 | that is attempting to load the PA-RISC library. A PA-RISC shared | |
304 | library cannot be loaded into an Itanium executable nor vice-versa. | |
305 | ||
f2a260d6 GS |
306 | To create a shared library, the following steps must be performed: |
307 | ||
af8e01f2 MB |
308 | 1. Compile source modules with +z or +Z flag to create a .o module |
309 | which contains Position-Independent Code (PIC). The linker will | |
310 | tell you in the next step if +Z was needed. | |
311 | (For gcc, the appropriate flag is -fpic or -fPIC.) | |
f2a260d6 | 312 | |
af8e01f2 MB |
313 | 2. Link the shared library using the -b flag. If the code calls |
314 | any functions in other system libraries (e.g., libm), it must | |
315 | be included on this line. | |
f2a260d6 GS |
316 | |
317 | (Note that these steps are usually handled automatically by the extension's | |
318 | Makefile). | |
319 | ||
320 | If these dependent libraries are not listed at shared library creation | |
321 | time, you will get fatal "Unresolved symbol" errors at run time when the | |
322 | library is loaded. | |
323 | ||
a75f7dba | 324 | You may create a shared library that refers to another library, which |
60ed1d8c GS |
325 | may be either an archive library or a shared library. If this second |
326 | library is a shared library, this is called a "dependent library". The | |
327 | dependent library's name is recorded in the main shared library, but it | |
328 | is not linked into the shared library. Instead, it is loaded when the | |
329 | main shared library is loaded. This can cause problems if you build an | |
330 | extension on one system and move it to another system where the | |
331 | libraries may not be located in the same place as on the first system. | |
f2a260d6 GS |
332 | |
333 | If the referred library is an archive library, then it is treated as a | |
334 | simple collection of .o modules (all of which must contain PIC). These | |
335 | modules are then linked into the shared library. | |
336 | ||
60ed1d8c GS |
337 | Note that it is okay to create a library which contains a dependent |
338 | library that is already linked into perl. | |
f2a260d6 | 339 | |
42be3f00 JH |
340 | Some extensions, like DB_File and Compress::Zlib use/require prebuilt |
341 | libraries for the perl extensions/modules to work. If these libraries | |
3853ea39 JH |
342 | are built using the default configuration, it might happen that you |
343 | run into an error like "invalid loader fixup" during load phase. | |
344 | HP is aware of this problem. Search the HP-UX cxx-dev forums for | |
345 | discussions about the subject. The short answer is that B<everything> | |
346 | (all libraries, everything) must be compiled with C<+z> or C<+Z> to be | |
b48c3bfb AD |
347 | PIC (position independent code). (For gcc, that would be |
348 | C<-fpic> or C<-fPIC>). In HP-UX 11.00 or newer the linker | |
3853ea39 | 349 | error message should tell the name of the offending object file. |
42be3f00 JH |
350 | |
351 | A more general approach is to intervene manually, as with an example for | |
352 | the DB_File module, which requires SleepyCat's libdb.sl: | |
353 | ||
af8e01f2 MB |
354 | # cd .../db-3.2.9/build_unix |
355 | # vi Makefile | |
356 | ... add +Z to all cflags to create shared objects | |
357 | CFLAGS= -c $(CPPFLAGS) +Z -Ae +O2 +Onolimit \ | |
c8fb9d34 | 358 | -I/usr/local/include -I/usr/include/X11R6 |
af8e01f2 | 359 | CXXFLAGS= -c $(CPPFLAGS) +Z -Ae +O2 +Onolimit \ |
c8fb9d34 | 360 | -I/usr/local/include -I/usr/include/X11R6 |
af8e01f2 MB |
361 | |
362 | # make clean | |
363 | # make | |
364 | # mkdir tmp | |
365 | # cd tmp | |
366 | # ar x ../libdb.a | |
367 | # ld -b -o libdb-3.2.sl *.o | |
368 | # mv libdb-3.2.sl /usr/local/lib | |
369 | # rm *.o | |
370 | # cd /usr/local/lib | |
371 | # rm -f libdb.sl | |
372 | # ln -s libdb-3.2.sl libdb.sl | |
373 | ||
374 | # cd .../DB_File-1.76 | |
375 | # make distclean | |
376 | # perl Makefile.PL | |
377 | # make | |
378 | # make test | |
379 | # make install | |
380 | ||
381 | As of db-4.2.x it is no longer needed to do this by hand. Sleepycat | |
382 | has changed the configuration process to add +z on HP-UX automatically. | |
383 | ||
384 | # cd .../db-4.2.25/build_unix | |
6a555251 | 385 | # env CFLAGS=+DD64 LDFLAGS=+DD64 ../dist/configure |

386 | |
387 | should work to generate 64bit shared libraries for HP-UX 11.00 and 11i. | |
42be3f00 | 388 | |
13e84f2c JH |
389 | It is no longer possible to link PA-RISC 1.0 shared libraries (even |
390 | though the command-line flags are still present). | |
391 | ||
392 | PA-RISC and Itanium object files are not interchangeable. Although | |
393 | you may be able to use ar to create an archive library of PA-RISC | |
394 | object files on an Itanium system, you cannot link against it using | |
395 | an Itanium link editor. | |

42be3f00 JH |
401 | file (though see the section on 64-bit perl below). If you are using a |
402 | recent version of the Perl distribution, these flags are set automatically. | |

404 | Even though HP-UX 10.20 and 11.00 are not actively maintained by HP |
405 | anymore, updates for the HP ANSI C compiler are still available from | |
406 | time to time, and it might be advisable to see if updates are applicable. | |
407 | At the moment of writing, the latests available patches for 11.00 that | |
408 | should be applied are PHSS_35098, PHSS_35175, PHSS_35100, PHSS_33036, | |

412 | =head2 The GNU C Compiler |
413 | ||
414 | When you are going to use the GNU C compiler (gcc), and you don't have | |

464a08e7 | 416 | from e.g. L<http://gcc.gnu.org/mirrors.html>) or fetch |
34d14706 MB |
417 | a prebuilt binary from the HP porting center |
418 | at L<http://hpux.connect.org.uk/hppd/cgi-bin/search?term=gcc&Search=Search> | |
419 | or from the DSPP (you need to be a member) at | |
420 | L<http://h21007.www2.hp.com/portal/site/dspp/menuitem.863c3e4cbcdc3f3515b49c108973a801?ciid=2a08725cc2f02110725cc2f02110275d6e10RCRD&jumpid=reg_r1002_usen_c-001_title_r0001> | |

421 | (Browse through the list, because there are often multiple versions of |
422 | the same package available). | |
2be3a552 | 423 | |
34d14706 | 424 | Most mentioned distributions are depots. H.Merijn Brand has made prebuilt |
635d4d9b | 425 | gcc binaries available on L<http://mirrors.develooper.com/hpux/> and/or |
34d14706 MB |
426 | L<http://www.cmve.net/~merijn/> for HP-UX 10.20 (only 32bit), HP-UX 11.00, |
427 | HP-UX 11.11 (HP-UX 11i v1), and HP-UX 11.23 (HP-UX 11i v2 PA-RISC) in both | |
428 | 32- and 64-bit versions. For HP-UX 11.23 IPF and HP-UX 11.31 IPF depots are | |
429 | available too. The IPF versions do not need two versions of GNU gcc. | |
b20ef1a8 MB |
430 | |
431 | On PA-RISC you need a different compiler for 32-bit applications and for | |
432 | 64-bit applications. On PA-RISC, 32-bit objects and 64-bit objects do | |
fb1ee0ec | 433 | not mix. Period. There is no different behaviour for HP C-ANSI-C or GNU |
b20ef1a8 | 434 | gcc. So if you require your perl binary to use 64-bit libraries, like |
1d69df2b | 435 | Oracle-64bit, you MUST build a 64-bit perl. |
b20ef1a8 | 436 | |
1d69df2b MHM |
437 | Building a 64-bit capable gcc on PA-RISC from source is possible only when |
438 | you have the HP C-ANSI C compiler or an already working 64-bit binary of | |
b20ef1a8 MB |
439 | gcc available. Best performance for perl is achieved with HP's native |
440 | compiler. | |

a83b6f46 | 442 | =head2 Using Large Files with Perl on HP-UX |
f2a260d6 | 443 | |
60ed1d8c GS |
444 | Beginning with HP-UX version 10.20, files larger than 2GB (2^31 bytes) |
445 | may be created and manipulated. Three separate methods of doing this | |
446 | are available. Of these methods, the best method for Perl is to compile | |
447 | using the -Duselargefiles flag to Configure. This causes Perl to be | |
448 | compiled using structures and functions in which these are 64 bits wide, | |
449 | rather than 32 bits wide. (Note that this will only work with HP's ANSI | |
450 | C compiler. If you want to compile Perl using gcc, you will have to get | |
aca48073 | 451 | a version of the compiler that supports 64-bit operations. See above for |
f3e4a94e | 452 | where to find it.) |
60ed1d8c GS |
453 | |
454 | There are some drawbacks to this approach. One is that any extension | |
455 | which calls any file-manipulating C function will need to be recompiled | |
f74a9bd3 GS |
456 | (just follow the usual "perl Makefile.PL; make; make test; make install" |
457 | procedure). | |
60ed1d8c | 458 | |
d66be8f9 | 459 | The list of functions that will need to recompiled is: |
c8fb9d34 MB |
460 | creat, fgetpos, fopen, |
461 | freopen, fsetpos, fstat, | |
462 | fstatvfs, fstatvfsdev, ftruncate, | |
463 | ftw, lockf, lseek, | |
464 | lstat, mmap, nftw, | |
465 | open, prealloc, stat, | |
466 | statvfs, statvfsdev, tmpfile, | |
467 | truncate, getrlimit, setrlimit | |
f2a260d6 | 468 | |
60ed1d8c GS |
469 | Another drawback is only valid for Perl versions before 5.6.0. This |
470 | drawback is that the seek and tell functions (both the builtin version | |
471 | and POSIX module version) will not perform correctly. | |
472 | ||
473 | It is strongly recommended that you use this flag when you run | |
474 | Configure. If you do not do this, but later answer the question about | |
475 | large files when Configure asks you, you may get a configuration that | |
476 | cannot be compiled, or that does not function as expected. | |

a83b6f46 | 478 | =head2 Threaded Perl on HP-UX |
f2a260d6 | 479 | |
c7d9b096 JH |
480 | It is possible to compile a version of threaded Perl on any version of |
481 | HP-UX before 10.30, but it is strongly suggested that you be running on | |
f2a260d6 GS |
482 | HP-UX 11.00 at least. |
483 | ||
60ed1d8c GS |
484 | To compile Perl with threads, add -Dusethreads to the arguments of |
485 | Configure. Verify that the -D_POSIX_C_SOURCE=199506L compiler flag is | |
486 | automatically added to the list of flags. Also make sure that -lpthread | |
42be3f00 JH |
487 | is listed before -lc in the list of libraries to link Perl with. The |
488 | hints provided for HP-UX during Configure will try very hard to get | |
489 | this right for you. | |
f2a260d6 | 490 | |
210b36aa | 491 | HP-UX versions before 10.30 require a separate installation of a POSIX |
c7d9b096 JH |
492 | threads library package. Two examples are the HP DCE package, available |
493 | on "HP-UX Hardware Extensions 3.0, Install and Core OS, Release 10.20, | |
494 | April 1999 (B3920-13941)" or the Freely available PTH package, available | |
635d4d9b | 495 | on H.Merijn's site (L<http://mirrors.develooper.com/hpux/>). The use of PTH |
30026e36 | 496 | will be unsupported in perl-5.12 and up and is rather buggy in 5.11.x. |
c7d9b096 | 497 | |
fa01be49 MB |
498 | If you are going to use the HP DCE package, the library used for threading |
499 | is /usr/lib/libcma.sl, but there have been multiple updates of that | |
500 | library over time. Perl will build with the first version, but it | |
501 | will not pass the test suite. Older Oracle versions might be a compelling | |
8e4bcd96 | 502 | reason not to update that library, otherwise please find a newer version |

a83b6f46 | 533 | =head2 64-bit Perl on HP-UX |
f2a260d6 | 534 | |
60ed1d8c GS |
535 | Beginning with HP-UX 11.00, programs compiled under HP-UX can take |
536 | advantage of the LP64 programming environment (LP64 means Longs and | |
b204bbd5 MB |
537 | Pointers are 64 bits wide), in which scalar variables will be able |
538 | to hold numbers larger than 2^32 with complete precision. Perl has | |
539 | proven to be consistent and reliable in 64bit mode since 5.8.1 on | |
540 | all HP-UX 11.xx. | |
f2a260d6 | 541 | |
70dff5ba | 542 | As of the date of this document, Perl is fully 64-bit compliant on |
b20ef1a8 | 543 | HP-UX 11.00 and up for both cc- and gcc builds. If you are about to |
1d69df2b | 544 | build a 64-bit perl with GNU gcc, please read the gcc section carefully. |
f2a260d6 | 545 | |
b204bbd5 MB |
546 | Should a user have the need for compiling Perl in the LP64 environment, |
547 | use the -Duse64bitall flag to Configure. This will force Perl to be | |
548 | compiled in a pure LP64 environment (with the +DD64 flag for HP C-ANSI-C, | |
549 | with no additional options for GNU gcc 64-bit on PA-RISC, and with | |
550 | -mlp64 for GNU gcc on Itanium). | |
b20ef1a8 | 551 | If you want to compile Perl using gcc, you will have to get a version of |
aca48073 | 552 | the compiler that supports 64-bit operations.) |
f74a9bd3 | 553 | |
60ed1d8c GS |
554 | You can also use the -Duse64bitint flag to Configure. Although there |
555 | are some minor differences between compiling Perl with this flag versus | |
556 | the -Duse64bitall flag, they should not be noticeable from a Perl user's | |
b204bbd5 MB |
557 | perspective. When configuring -Duse64bitint using a 64bit gcc on a |
558 | pa-risc architecture, -Duse64bitint is silently promoted to -Duse64bitall. | |
f74a9bd3 | 559 | |
60ed1d8c GS |
560 | In both cases, it is strongly recommended that you use these flags when |
561 | you run Configure. If you do not use do this, but later answer the | |
562 | questions about 64-bit numbers when Configure asks you, you may get a | |
563 | configuration that cannot be compiled, or that does not function as | |
564 | expected. | |

568 | Using perl to connect to Oracle databases through DBI and DBD::Oracle | |
569 | has caused a lot of people many headaches. Read README.hpux in the | |
570 | DBD::Oracle for much more information. The reason to mention it here | |
571 | is that Oracle requires a perl built with libcl and libpthread, the | |
572 | latter even when perl is build without threads. Building perl using | |
573 | all defaults, but still enabling to build DBD::Oracle later on can be | |
574 | achieved using | |

585 | If you attempt to compile Perl with (POSIX) threads on an 11.X system |
586 | and also link in the GDBM library, then Perl will immediately core dump | |
587 | when it starts up. The only workaround at this point is to relink the | |
588 | GDBM library under 11.X, then relink it into Perl. | |
589 | ||
590 | the error might show something like: | |

a83b6f46 | 604 | =head2 HP-UX Kernel Parameters (maxdsiz) for Compiling Perl |
13e84f2c JH |
605 | |
606 | By default, HP-UX comes configured with a maximum data segment size of | |
607 | 64MB. This is too small to correctly compile Perl with the maximum | |
608 | optimization levels. You can increase the size of the maxdsiz kernel | |
609 | parameter through the use of SAM. | |
610 | ||
611 | When using the GUI version of SAM, click on the Kernel Configuration | |
612 | icon, then the Configurable Parameters icon. Scroll down and select | |
613 | the maxdsiz line. From the Actions menu, select the Modify Configurable | |
614 | Parameter item. Insert the new formula into the Formula/Value box. | |
615 | Then follow the instructions to rebuild your kernel and reboot your | |
616 | system. | |
617 | ||
618 | In general, a value of 256MB (or "256*1024*1024") is sufficient for | |
619 | Perl to compile at maximum optimization. | |

638 | The key here is the C<nss_delete> call. One workaround for this | |
639 | bug seems to be to create add to the file F</etc/nsswitch.conf> | |
640 | (at least) the following lines | |
641 | ||
48529397 | 642 | group: files |

643 | passwd: files |

645 | Whether you are using NIS does not matter. Amazingly enough, | |
3a1825b5 | 646 | the same bug also affects Solaris. |

650 | There seems to be a broken system header file in HP-UX 11.00 that | |
651 | breaks perl building in 32bit mode with GNU gcc-4.x causing this | |
652 | error. The same file for HP-UX 11.11 (even though the file is older) | |
653 | does not show this failure, and has the correct definition, so the | |
654 | best fix is to patch the header to match: | |

671 | earlier than 11.31 but are harmless: | |

695 | HP-UX 11 Y2K patch "Y2K-1100 B.11.00.B0125 HP-UX Core OS Year 2000 | |
696 | Patch Bundle" has been reported to break the io/fs test #18 which | |
697 | tests whether utime() can change timestamps. The Y2K patch seems to | |
698 | break utime() so that over NFS the timestamps do not get changed | |
699 | (on local filesystems utime() still works). This has probably been | |
700 | fixed on your system by now. | |
