6 perlhpux - Perl version 5 on Hewlett-Packard Unix (HP-UX) systems
7
9 This document describes various features of HP's Unix operating system
10 (HP-UX) that will affect how Perl version 5 (hereafter just Perl) is
11 compiled and/or runs.
12
13 Using perl as shipped with HP-UX
14 Application release September 2001, HP-UX 11.00 is the first to ship
15 with Perl. By the time it was perl-5.6.1 in /opt/perl. The first
16 occurrence is on CD 5012-7954 and can be installed using
17
18 swinstall -s /cdrom perl
19
20 assuming you have mounted that CD on /cdrom.
21
22 That build was a portable hppa-1.1 multithread build that supports
23 large files compiled with gcc-2.9-hppa-991112.
24
25 If you perform a new installation, then (a newer) Perl will be
26 installed automatically. Pre-installed HP-UX systems now have more
27 recent versions of Perl and the updated modules.
28
29 The official (threaded) builds from HP, as they are shipped on the
30 Application DVD/CD's are available on
31 <http://www.software.hp.com/portal/swdepot/displayProductInfo.do?productNumber=PERL>
32 for both PA-RISC and IPF (Itanium Processor Family). They are built
33 with the HP ANSI-C compiler. Up till 5.8.8 that was done by
34 ActiveState.
35
36 To see what version is included on the DVD (assumed here to be mounted
37 on /cdrom), issue this command:
38
39 # swlist -s /cdrom perl
40 # perl D.5.8.8.B 5.8.8 Perl Programming Language
41 perl.Perl5-32 D.5.8.8.B 32-bit 5.8.8 Perl Programming Language
42 with Extensions
43 perl.Perl5-64 D.5.8.8.B 64-bit 5.8.8 Perl Programming Language
44 with Extensions
45
46 To see what is installed on your system:
47
48 # swlist -R perl
49 # perl E.5.8.8.J Perl Programming Language
50 # perl.Perl5-32 E.5.8.8.J 32-bit Perl Programming Language

57 perl.Perl5-64.PERL-RUN E.5.8.8.J 64-bit Perl Binaries for IA
58
59 Using perl from HP's porting centre
60 HP porting centre tries to keep up with customer demand and release
61 updates from the Open Source community. Having precompiled Perl
62 binaries available is obvious, though "up-to-date" is something
63 relative. At the moment of writing only perl-5.10.1 was available (with
64 5.16.3 being the latest stable release from the porters point of view).
65
66 The HP porting centres are limited in what systems they are allowed to
67 port to and they usually choose the two most recent OS versions
68 available.
69
70 HP has asked the porting centre to move Open Source binaries from /opt
71 to /usr/local, so binaries produced since the start of July 2002 are
72 located in /usr/local.
73
74 One of HP porting centres URL's is <http://hpux.connect.org.uk/> The
75 port currently available is built with GNU gcc.
76
77 Other prebuilt perl binaries
78 To get even more recent perl depots for the whole range of HP-UX, visit
79 H.Merijn Brand's site at <http://mirrors.develooper.com/hpux/#Perl>.
80 Carefully read the notes to see if the available versions suit your
81 needs.
82
83 Compiling Perl 5 on HP-UX
84 When compiling Perl, you must use an ANSI C compiler. The C compiler
85 that ships with all HP-UX systems is a K&R compiler that should only be
86 used to build new kernels.
87
88 Perl can be compiled with either HP's ANSI C compiler or with gcc. The
89 former is recommended, as not only can it compile Perl with no
90 difficulty, but also can take advantage of features listed later that
91 require the use of HP compiler-specific command-line flags.
92
93 If you decide to use gcc, make sure your installation is recent and
94 complete, and be sure to read the Perl INSTALL file for more gcc-
95 specific details.
96
97 PA-RISC
98 HP's HP9000 Unix systems run on HP's own Precision Architecture (PA-
99 RISC) chip. HP-UX used to run on the Motorola MC68000 family of chips,
100 but any machine with this chip in it is quite obsolete and this
101 document will not attempt to address issues for compiling Perl on the
102 Motorola chipset.
103
104 The version of PA-RISC at the time of this document's last update is
105 2.0, which is also the last there will be. HP PA-RISC systems are
106 usually referred to with model description "HP 9000". The last CPU in
107 this series is the PA-8900. Support for PA-RISC architectured machines
108 officially ends as shown in the following table:

131 From <http://www.hp.com/products1/evolution/9000/faqs.html>
132
133 The last order date for HP 9000 systems was December 31, 2008.
134
135 A complete list of models at the time the OS was built is in the file
136 /usr/sam/lib/mo/sched.models. The first column corresponds to the last
137 part of the output of the "model" command. The second column is the
138 PA-RISC version and the third column is the exact chip type used.
139 (Start browsing at the bottom to prevent confusion ;-)

145
146 Portability Between PA-RISC Versions
147 An executable compiled on a PA-RISC 2.0 platform will not execute on a
148 PA-RISC 1.1 platform, even if they are running the same version of HP-
149 UX. If you are building Perl on a PA-RISC 2.0 platform and want that
150 Perl to also run on a PA-RISC 1.1, the compiler flags +DAportable and
151 +DS32 should be used.
152
153 It is no longer possible to compile PA-RISC 1.0 executables on either
154 the PA-RISC 1.1 or 2.0 platforms. The command-line flags are accepted,
155 but the resulting executable will not run when transferred to a PA-RISC
156 1.0 system.
157
158 PA-RISC 1.0
159 The original version of PA-RISC, HP no longer sells any system with
160 this chip.
161
162 The following systems contained PA-RISC 1.0 chips:
163
164 600, 635, 645, 808, 815, 822, 825, 832, 834, 835, 840, 842, 845, 850,
165 852, 855, 860, 865, 870, 890
166
167 PA-RISC 1.1
168 An upgrade to the PA-RISC design, it shipped for many years in many
169 different system.
170
171 The following systems contain with PA-RISC 1.1 chips:
172
173 705, 710, 712, 715, 720, 722, 725, 728, 730, 735, 742, 743, 744, 745,

184 PA-RISC 2.0
185 The most recent upgrade to the PA-RISC design, it added support for
186 64-bit integer data.
187
188 As of the date of this document's last update, the following systems
189 contain PA-RISC 2.0 chips:
190

200 Just before HP took over Compaq, some systems were renamed. the link
201 that contained the explanation is dead, so here's a short summary:
202
203 HP 9000 A-Class servers, now renamed HP Server rp2400 series.
204 HP 9000 L-Class servers, now renamed HP Server rp5400 series.
205 HP 9000 N-Class servers, now renamed HP Server rp7400.
206
207 rp2400, rp2405, rp2430, rp2450, rp2470, rp3410, rp3440, rp4410,
208 rp4440, rp5400, rp5405, rp5430, rp5450, rp5470, rp7400, rp7405,
209 rp7410, rp7420, rp7440, rp8400, rp8420, rp8440, Superdome
210
211 The current naming convention is:
212
213 aadddd
214 ||||`+- 00 - 99 relative capacity & newness (upgrades, etc.)
215 |||`--- unique number for each architecture to ensure different
216 ||| systems do not have the same numbering across
217 ||| architectures
218 ||`---- 1 - 9 identifies family and/or relative positioning
219 ||
220 |`----- c = ia32 (cisc)
221 | p = pa-risc
222 | x = ia-64 (Itanium & Itanium 2)
223 | h = housing
224 `------ t = tower
225 r = rack optimized
226 s = super scalable
227 b = blade
228 sa = appliance
229
230 Itanium Processor Family (IPF) and HP-UX
231 HP-UX also runs on the new Itanium processor. This requires the use of
232 a different version of HP-UX (currently 11.23 or 11i v2), and with the
233 exception of a few differences detailed below and in later sections,
234 Perl should compile with no problems.
235
236 Although PA-RISC binaries can run on Itanium systems, you should not
237 attempt to use a PA-RISC version of Perl on an Itanium system. This is
238 because shared libraries created on an Itanium system cannot be loaded
239 while running a PA-RISC executable.
240
241 HP Itanium 2 systems are usually referred to with model description "HP
242 Integrity".
243
244 Itanium, Itanium 2 & Madison 6
245 HP also ships servers with the 128-bit Itanium processor(s). The cx26x0
246 is told to have Madison 6. As of the date of this document's last
247 update, the following systems contain Itanium or Itanium 2 chips (this
248 is likely to be out of date):
249
250 BL60p, BL860c, BL870c, BL890c, cx2600, cx2620, rx1600, rx1620, rx2600,
251 rx2600hptc, rx2620, rx2660, rx2800, rx3600, rx4610, rx4640, rx5670,
252 rx6600, rx7420, rx7620, rx7640, rx8420, rx8620, rx8640, rx9610,

276
277 Building Dynamic Extensions on HP-UX
278 HP-UX supports dynamically loadable libraries (shared libraries).
279 Shared libraries end with the suffix .sl. On Itanium systems, they end
280 with the suffix .so.
281
282 Shared libraries created on a platform using a particular PA-RISC
283 version are not usable on platforms using an earlier PA-RISC version by
284 default. However, this backwards compatibility may be enabled using
285 the same +DAportable compiler flag (with the same PA-RISC 1.0 caveat
286 mentioned above).
287
288 Shared libraries created on an Itanium platform cannot be loaded on a
289 PA-RISC platform. Shared libraries created on a PA-RISC platform can
290 only be loaded on an Itanium platform if it is a PA-RISC executable
291 that is attempting to load the PA-RISC library. A PA-RISC shared
292 library cannot be loaded into an Itanium executable nor vice-versa.
293
294 To create a shared library, the following steps must be performed:
295
296 1. Compile source modules with +z or +Z flag to create a .o module
297 which contains Position-Independent Code (PIC). The linker will
298 tell you in the next step if +Z was needed.
299 (For gcc, the appropriate flag is -fpic or -fPIC.)
300
301 2. Link the shared library using the -b flag. If the code calls
302 any functions in other system libraries (e.g., libm), it must
303 be included on this line.
304
305 (Note that these steps are usually handled automatically by the
306 extension's Makefile).
307
308 If these dependent libraries are not listed at shared library creation
309 time, you will get fatal "Unresolved symbol" errors at run time when
310 the library is loaded.
311
312 You may create a shared library that refers to another library, which
313 may be either an archive library or a shared library. If this second
314 library is a shared library, this is called a "dependent library". The
315 dependent library's name is recorded in the main shared library, but it
316 is not linked into the shared library. Instead, it is loaded when the
317 main shared library is loaded. This can cause problems if you build an
318 extension on one system and move it to another system where the
319 libraries may not be located in the same place as on the first system.
320
321 If the referred library is an archive library, then it is treated as a
322 simple collection of .o modules (all of which must contain PIC). These
323 modules are then linked into the shared library.
324
325 Note that it is okay to create a library which contains a dependent
326 library that is already linked into perl.
327
328 Some extensions, like DB_File and Compress::Zlib use/require prebuilt
329 libraries for the perl extensions/modules to work. If these libraries
330 are built using the default configuration, it might happen that you run
331 into an error like "invalid loader fixup" during load phase. HP is
332 aware of this problem. Search the HP-UX cxx-dev forums for discussions
333 about the subject. The short answer is that everything (all libraries,
334 everything) must be compiled with "+z" or "+Z" to be PIC (position
335 independent code). (For gcc, that would be "-fpic" or "-fPIC"). In
336 HP-UX 11.00 or newer the linker error message should tell the name of
337 the offending object file.
338
339 A more general approach is to intervene manually, as with an example
340 for the DB_File module, which requires SleepyCat's libdb.sl:
341
342 # cd .../db-3.2.9/build_unix
343 # vi Makefile
344 ... add +Z to all cflags to create shared objects
345 CFLAGS= -c $(CPPFLAGS) +Z -Ae +O2 +Onolimit \
346 -I/usr/local/include -I/usr/include/X11R6
347 CXXFLAGS= -c $(CPPFLAGS) +Z -Ae +O2 +Onolimit \
348 -I/usr/local/include -I/usr/include/X11R6
349
350 # make clean
351 # make
352 # mkdir tmp
353 # cd tmp
354 # ar x ../libdb.a
355 # ld -b -o libdb-3.2.sl *.o
356 # mv libdb-3.2.sl /usr/local/lib
357 # rm *.o
358 # cd /usr/local/lib
359 # rm -f libdb.sl
360 # ln -s libdb-3.2.sl libdb.sl
361
362 # cd .../DB_File-1.76
363 # make distclean
364 # perl Makefile.PL
365 # make
366 # make test
367 # make install
368
369 As of db-4.2.x it is no longer needed to do this by hand. Sleepycat has
370 changed the configuration process to add +z on HP-UX automatically.
371
372 # cd .../db-4.2.25/build_unix
373 # env CFLAGS=+DD64 LDFLAGS=+DD64 ../dist/configure
374
375 should work to generate 64bit shared libraries for HP-UX 11.00 and 11i.
376
377 It is no longer possible to link PA-RISC 1.0 shared libraries (even
378 though the command-line flags are still present).
379
380 PA-RISC and Itanium object files are not interchangeable. Although you
381 may be able to use ar to create an archive library of PA-RISC object
382 files on an Itanium system, you cannot link against it using an Itanium
383 link editor.
384
385 The HP ANSI C Compiler
386 When using this compiler to build Perl, you should make sure that the
387 flag -Aa is added to the cpprun and cppstdin variables in the config.sh
388 file (though see the section on 64-bit perl below). If you are using a
389 recent version of the Perl distribution, these flags are set
390 automatically.
391
392 Even though HP-UX 10.20 and 11.00 are not actively maintained by HP
393 anymore, updates for the HP ANSI C compiler are still available from
394 time to time, and it might be advisable to see if updates are
395 applicable. At the moment of writing, the latests available patches
396 for 11.00 that should be applied are PHSS_35098, PHSS_35175,
397 PHSS_35100, PHSS_33036, and PHSS_33902). If you have a SUM account, you
398 can use it to search for updates/patches. Enter "ANSI" as keyword.
399
400 The GNU C Compiler
401 When you are going to use the GNU C compiler (gcc), and you don't have
402 gcc yet, you can either build it yourself from the sources (available
403 from e.g. <http://gcc.gnu.org/mirrors.html>) or fetch a prebuilt binary
404 from the HP porting center at
405 <http://hpux.connect.org.uk/hppd/cgi-bin/search?term=gcc&Search=Search>

411 Most mentioned distributions are depots. H.Merijn Brand has made
412 prebuilt gcc binaries available on
413 <http://mirrors.develooper.com/hpux/> and/or
414 <http://www.cmve.net/~merijn/> for HP-UX 10.20 (only 32bit), HP-UX
415 11.00, HP-UX 11.11 (HP-UX 11i v1), and HP-UX 11.23 (HP-UX 11i v2 PA-
416 RISC) in both 32- and 64-bit versions. For HP-UX 11.23 IPF and HP-UX
417 11.31 IPF depots are available too. The IPF versions do not need two
418 versions of GNU gcc.
419
420 On PA-RISC you need a different compiler for 32-bit applications and
421 for 64-bit applications. On PA-RISC, 32-bit objects and 64-bit objects
422 do not mix. Period. There is no different behaviour for HP C-ANSI-C or
423 GNU gcc. So if you require your perl binary to use 64-bit libraries,
424 like Oracle-64bit, you MUST build a 64-bit perl.
425
426 Building a 64-bit capable gcc on PA-RISC from source is possible only
427 when you have the HP C-ANSI C compiler or an already working 64-bit
428 binary of gcc available. Best performance for perl is achieved with
429 HP's native compiler.
430
431 Using Large Files with Perl on HP-UX
432 Beginning with HP-UX version 10.20, files larger than 2GB (2^31 bytes)
433 may be created and manipulated. Three separate methods of doing this
434 are available. Of these methods, the best method for Perl is to
435 compile using the -Duselargefiles flag to Configure. This causes Perl
436 to be compiled using structures and functions in which these are 64
437 bits wide, rather than 32 bits wide. (Note that this will only work
438 with HP's ANSI C compiler. If you want to compile Perl using gcc, you
439 will have to get a version of the compiler that supports 64-bit
440 operations. See above for where to find it.)
441
442 There are some drawbacks to this approach. One is that any extension
443 which calls any file-manipulating C function will need to be recompiled
444 (just follow the usual "perl Makefile.PL; make; make test; make
445 install" procedure).
446
447 The list of functions that will need to recompiled is:
448 creat, fgetpos, fopen,
449 freopen, fsetpos, fstat,
450 fstatvfs, fstatvfsdev, ftruncate,
451 ftw, lockf, lseek,
452 lstat, mmap, nftw,
453 open, prealloc, stat,
454 statvfs, statvfsdev, tmpfile,
455 truncate, getrlimit, setrlimit
456
457 Another drawback is only valid for Perl versions before 5.6.0. This
458 drawback is that the seek and tell functions (both the builtin version
459 and POSIX module version) will not perform correctly.
460
461 It is strongly recommended that you use this flag when you run
462 Configure. If you do not do this, but later answer the question about
463 large files when Configure asks you, you may get a configuration that
464 cannot be compiled, or that does not function as expected.
465
466 Threaded Perl on HP-UX
467 It is possible to compile a version of threaded Perl on any version of
468 HP-UX before 10.30, but it is strongly suggested that you be running on
469 HP-UX 11.00 at least.
470
471 To compile Perl with threads, add -Dusethreads to the arguments of
472 Configure. Verify that the -D_POSIX_C_SOURCE=199506L compiler flag is
473 automatically added to the list of flags. Also make sure that
474 -lpthread is listed before -lc in the list of libraries to link Perl
475 with. The hints provided for HP-UX during Configure will try very hard
476 to get this right for you.
477
478 HP-UX versions before 10.30 require a separate installation of a POSIX
479 threads library package. Two examples are the HP DCE package, available
480 on "HP-UX Hardware Extensions 3.0, Install and Core OS, Release 10.20,
481 April 1999 (B3920-13941)" or the Freely available PTH package,
482 available on H.Merijn's site (<http://mirrors.develooper.com/hpux/>).
483 The use of PTH will be unsupported in perl-5.12 and up and is rather
484 buggy in 5.11.x.
485
486 If you are going to use the HP DCE package, the library used for
487 threading is /usr/lib/libcma.sl, but there have been multiple updates
488 of that library over time. Perl will build with the first version, but
489 it will not pass the test suite. Older Oracle versions might be a
490 compelling reason not to update that library, otherwise please find a
491 newer version in one of the following patches: PHSS_19739, PHSS_20608,
492 or PHSS_23672

511 If you choose for the PTH package, use swinstall to install pth in the
512 default location (/opt/pth), and then make symbolic links to the
513 libraries from /usr/lib
514
515 # cd /usr/lib
516 # ln -s /opt/pth/lib/libpth* .
517
518 For building perl to support Oracle, it needs to be linked with libcl
519 and libpthread. So even if your perl is an unthreaded build, these
520 libraries might be required. See "Oracle on HP-UX" below.
521
522 64-bit Perl on HP-UX
523 Beginning with HP-UX 11.00, programs compiled under HP-UX can take
524 advantage of the LP64 programming environment (LP64 means Longs and
525 Pointers are 64 bits wide), in which scalar variables will be able to
526 hold numbers larger than 2^32 with complete precision. Perl has proven
527 to be consistent and reliable in 64bit mode since 5.8.1 on all HP-UX
528 11.xx.
529
530 As of the date of this document, Perl is fully 64-bit compliant on HP-
531 UX 11.00 and up for both cc- and gcc builds. If you are about to build
532 a 64-bit perl with GNU gcc, please read the gcc section carefully.
533
534 Should a user have the need for compiling Perl in the LP64 environment,
535 use the -Duse64bitall flag to Configure. This will force Perl to be
536 compiled in a pure LP64 environment (with the +DD64 flag for HP C-ANSI-
537 C, with no additional options for GNU gcc 64-bit on PA-RISC, and with
538 -mlp64 for GNU gcc on Itanium). If you want to compile Perl using gcc,
539 you will have to get a version of the compiler that supports 64-bit
540 operations.)
541
542 You can also use the -Duse64bitint flag to Configure. Although there
543 are some minor differences between compiling Perl with this flag versus
544 the -Duse64bitall flag, they should not be noticeable from a Perl
545 user's perspective. When configuring -Duse64bitint using a 64bit gcc on
546 a pa-risc architecture, -Duse64bitint is silently promoted to
547 -Duse64bitall.
548
549 In both cases, it is strongly recommended that you use these flags when
550 you run Configure. If you do not use do this, but later answer the
551 questions about 64-bit numbers when Configure asks you, you may get a
552 configuration that cannot be compiled, or that does not function as
553 expected.
554
555 Oracle on HP-UX
556 Using perl to connect to Oracle databases through DBI and DBD::Oracle
557 has caused a lot of people many headaches. Read README.hpux in the
558 DBD::Oracle for much more information. The reason to mention it here is
559 that Oracle requires a perl built with libcl and libpthread, the latter
560 even when perl is build without threads. Building perl using all
561 defaults, but still enabling to build DBD::Oracle later on can be
562 achieved using
563
564 Configure -A prepend:libswanted='cl pthread ' ...
565
566 Do not forget the space before the trailing quote.
567
568 Also note that this does not (yet) work with all configurations, it is
569 known to fail with 64-bit versions of GCC.
570
571 GDBM and Threads on HP-UX
572 If you attempt to compile Perl with (POSIX) threads on an 11.X system
573 and also link in the GDBM library, then Perl will immediately core dump
574 when it starts up. The only workaround at this point is to relink the
575 GDBM library under 11.X, then relink it into Perl.
576
577 the error might show something like:
578
579 Pthread internal error: message: __libc_reinit() failed, file:
580 ../pthreads/pthread.c, line: 1096 Return Pointer is 0xc082bf33 sh: 5345
581 Quit(coredump)
582
583 and Configure will give up.
584
585 NFS filesystems and utime(2) on HP-UX
586 If you are compiling Perl on a remotely-mounted NFS filesystem, the
587 test io/fs.t may fail on test #18. This appears to be a bug in HP-UX
588 and no fix is currently available.
589
590 HP-UX Kernel Parameters (maxdsiz) for Compiling Perl
591 By default, HP-UX comes configured with a maximum data segment size of
592 64MB. This is too small to correctly compile Perl with the maximum
593 optimization levels. You can increase the size of the maxdsiz kernel
594 parameter through the use of SAM.
595
596 When using the GUI version of SAM, click on the Kernel Configuration
597 icon, then the Configurable Parameters icon. Scroll down and select
598 the maxdsiz line. From the Actions menu, select the Modify
599 Configurable Parameter item. Insert the new formula into the
600 Formula/Value box. Then follow the instructions to rebuild your kernel
601 and reboot your system.
602
603 In general, a value of 256MB (or "256*1024*1024") is sufficient for
604 Perl to compile at maximum optimization.
605
607 You may get a bus error core dump from the op/pwent or op/grent tests.
608 If compiled with -g you will see a stack trace much like the following:
609
610 #0 0xc004216c in () from /usr/lib/libc.2
611 #1 0xc00d7550 in __nss_src_state_destr () from /usr/lib/libc.2
612 #2 0xc00d7768 in __nss_src_state_destr () from /usr/lib/libc.2
613 #3 0xc00d78a8 in nss_delete () from /usr/lib/libc.2
614 #4 0xc01126d8 in endpwent () from /usr/lib/libc.2

618 #8 0x23428 in perl_run () from ./perl
619 #9 0x2005c in main () from ./perl
620
621 The key here is the "nss_delete" call. One workaround for this bug
622 seems to be to create add to the file /etc/nsswitch.conf (at least) the
623 following lines
624
625 group: files
626 passwd: files
627
628 Whether you are using NIS does not matter. Amazingly enough, the same
629 bug also affects Solaris.
630
632 There seems to be a broken system header file in HP-UX 11.00 that
633 breaks perl building in 32bit mode with GNU gcc-4.x causing this error.
634 The same file for HP-UX 11.11 (even though the file is older) does not
635 show this failure, and has the correct definition, so the best fix is
636 to patch the header to match:
637

652 than 11.31 but are harmless:

677 whether utime() can change timestamps. The Y2K patch seems to break
678 utime() so that over NFS the timestamps do not get changed (on local
679 filesystems utime() still works). This has probably been fixed on your
680 system by now.
