README.hpux - Perl version 5 on Hewlett-Packard Unix (HP-UX) systems
swinstall -s /cdrom perl
assuming you have mounted that CD on /cdrom. In this version the following modules were installed:
ActivePerl::DocTools-0.04 HTML::Parser-3.19 XML::DOM-1.25 Archive::Tar-0.072 HTML::Tagset-3.03 XML::Parser-2.27 Compress::Zlib-1.08 MIME::Base64-2.11 XML::Simple-1.05 Convert::ASN1-0.10 Net-1.07 XML::XPath-1.09 Digest::MD5-2.11 PPM-2.1.5 XML::XSLT-0.32 File::CounterFile-0.12 SOAP::Lite-0.46 libwww-perl-5.51 Font::AFM-1.18 Storable-1.011 libxml-perl-0.07 HTML-Tree-3.11 URI-1.11 perl-ldap-0.23
The build was a portable hppa-1.1 multithread build that supports large files compiled with gcc-2.9-hppa-991112
If you perform a new installation, then Perl will be installed automatically.
More recent (preinstalled) HP-UX systems have more recent versions of Perl and the updated modules.
The HP porting centres are limited in what systems they are allowed to port to and they usually choose the two most recent OS versions available. This means that at the moment of writing, there are only HP-UX 11.11 (pa-risc 2.0) and HP-UX 11.23 (Itanium 2) ports available on the porting centres.
HP has asked the porting centre to move Open Source binaries from /opt to /usr/local, so binaries produced since the start of July 2002 are located in /usr/local.
One of HP porting centres URL's is http://hpux.connect.org.uk/ The port currently available is built with GNU gcc.
Perl can be compiled with either HP's ANSI C compiler or with gcc. The former is recommended, as not only can it compile Perl with no difficulty, but also can take advantage of features listed later that require the use of HP compiler-specific command-line flags.
If you decide to use gcc, make sure your installation is recent and complete, and be sure to read the Perl INSTALL file for more gcc-specific details.
The most recent version of PA-RISC at the time of this document's last update is 2.0. HP PA-RISC systems are usually refered to with model description ``HP 9000''.
A complete list of models at the time the OS was built is in the file /usr/sam/lib/mo/sched.models. The first column corresponds to the last part of the output of the ``model'' command. The second column is the PA-RISC version and the third column is the exact chip type used. (Start browsing at the bottom to prevent confusion ;-)
# model 9000/800/L1000-44 # grep L1000-44 /usr/sam/lib/mo/sched.models L1000-44 2.0 PA8500
It is no longer possible to compile PA-RISC 1.0 executables on either the PA-RISC 1.1 or 2.0 platforms. The command-line flags are accepted, but the resulting executable will not run when transferred to a PA-RISC 1.0 system.
The following systems contained PA-RISC 1.0 chips:
600, 635, 645, 808, 815, 822, 825, 832, 834, 835, 840, 842, 845, 850, 852, 855, 860, 865, 870, 890
The following systems contain with PA-RISC 1.1 chips:
705, 710, 712, 715, 720, 722, 725, 728, 730, 735, 742, 743, 744, 745, 747, 750, 755, 770, 777, 778, 779, 800, 801, 803, 806, 807, 809, 811, 813, 816, 817, 819, 821, 826, 827, 829, 831, 837, 839, 841, 847, 849, 851, 856, 857, 859, 867, 869, 877, 887, 891, 892, 897, A180, A180C, B115, B120, B132L, B132L+, B160L, B180L, C100, C110, C115, C120, C160L, D200, D210, D220, D230, D250, D260, D310, D320, D330, D350, D360, D410, DX0, DX5, DXO, E25, E35, E45, E55, F10, F20, F30, G30, G40, G50, G60, G70, H20, H30, H40, H50, H60, H70, I30, I40, I50, I60, I70, J200, J210, J210XC, K100, K200, K210, K220, K230, K400, K410, K420, S700i, S715, S744, S760, T500, T520
As of the date of this document's last update, the following systems contain PA-RISC 2.0 chips:
700, 780, 781, 782, 783, 785, 802, 804, 810, 820, 861, 871, 879, 889, 893, 895, 896, 898, 899, A400, A500, B1000, B2000, C130, C140, C160, C180, C180+, C180-XP, C200+, C400+, C3000, C360, C3600, CB260, D270, D280, D370, D380, D390, D650, J220, J2240, J280, J282, J400, J410, J5000, J5500XM, J5600, J7000, J7600, K250, K260, K260-EG, K270, K360, K370, K380, K450, K460, K460-EG, K460-XP, K470, K570, K580, L1000, L2000, L3000, N4000, R380, R390, SD16000, SD32000, SD64000, T540, T600, V2000, V2200, V2250, V2500, V2600
Just before HP took over Compaq, some systems were renamed. the link that contained the explanation is dead, so here's a short summary:
HP 9000 A-Class servers, now renamed HP Server rp2400 series. HP 9000 L-Class servers, now renamed HP Server rp5400 series. HP 9000 N-Class servers, now renamed HP Server rp7400.
rp2400, rp2405, rp2430, rp2450, rp2470, rp3410, rp3440, rp4410, rp4440, rp5400, rp5405, rp5430, rp5450, rp5470, rp7400, rp7405, rp7410, rp7420, rp8400, rp8420, Superdome
The current naming convention is:
aadddd ||||`+- 00 - 99 relative capacity & newness (upgrades, etc.) |||`--- unique number for each architecture to ensure different ||| systems do not have the same numbering across ||| architectures ||`---- 1 - 9 identifies family and/or relative positioning || |`----- c = ia32 (cisc) | p = pa-risc | x = ia-64 (Itanium & Itanium 2) | h = housing `------ t = tower r = rack optimized s = super scalable b = blade sa = appliance
Although PA-RISC binaries can run on Itanium systems, you should not attempt to use a PA-RISC version of Perl on an Itanium system. This is because shared libraries created on an Itanium system cannot be loaded while running a PA-RISC executable.
HP Itanium 2 systems are usually refered to with model description ``HP Integrity''.
BL60p, rx1600, rx1620, rx2600, rx2600hptc, rx2620, rx4610, rx4640, rx5670, rx7620, rx8620, rx9610
To see all about your machine, type
# model ia64 hp server rx2600 # /usr/contrib/bin/machinfo
Shared libraries created on a platform using a particular PA-RISC version are not usable on platforms using an earlier PA-RISC version by default. However, this backwards compatibility may be enabled using the same +DAportable compiler flag (with the same PA-RISC 1.0 caveat mentioned above).
Shared libraries created on an Itanium platform cannot be loaded on a PA-RISC platform. Shared libraries created on a PA-RISC platform can only be loaded on an Itanium platform if it is a PA-RISC executable that is attempting to load the PA-RISC library. A PA-RISC shared library cannot be loaded into an Itanium executable nor vice-versa.
To create a shared library, the following steps must be performed:
1. Compile source modules with +z or +Z flag to create a .o module which contains Position-Independent Code (PIC). The linker will tell you in the next step if +Z was needed. (For gcc, the appropriate flag is -fpic or -fPIC.)
2. Link the shared library using the -b flag. If the code calls any functions in other system libraries (e.g., libm), it must be included on this line.
(Note that these steps are usually handled automatically by the extension's Makefile).
If these dependent libraries are not listed at shared library creation time, you will get fatal ``Unresolved symbol'' errors at run time when the library is loaded.
You may create a shared library that refers to another library, which may be either an archive library or a shared library. If this second library is a shared library, this is called a ``dependent library''. The dependent library's name is recorded in the main shared library, but it is not linked into the shared library. Instead, it is loaded when the main shared library is loaded. This can cause problems if you build an extension on one system and move it to another system where the libraries may not be located in the same place as on the first system.
If the referred library is an archive library, then it is treated as a simple collection of .o modules (all of which must contain PIC). These modules are then linked into the shared library.
Note that it is okay to create a library which contains a dependent library that is already linked into perl.
Some extensions, like DB_File and Compress::Zlib use/require prebuilt libraries for the perl extensions/modules to work. If these libraries are built using the default configuration, it might happen that you run into an error like ``invalid loader fixup'' during load phase. HP is aware of this problem. Search the HP-UX cxx-dev forums for discussions about the subject. The short answer is that everything (all libraries, everything) must be compiled with "+z" or "+Z" to be PIC (position independent code). (For gcc, that would be "-fpic" or "-fPIC"). In HP-UX 11.00 or newer the linker error message should tell the name of the offending object file.
A more general approach is to intervene manually, as with an example for the DB_File module, which requires SleepyCat's libdb.sl:
# cd .../db-3.2.9/build_unix # vi Makefile ... add +Z to all cflags to create shared objects CFLAGS= -c $(CPPFLAGS) +Z -Ae +O2 +Onolimit \ -I/usr/local/include -I/usr/include/X11R6 CXXFLAGS= -c $(CPPFLAGS) +Z -Ae +O2 +Onolimit \ -I/usr/local/include -I/usr/include/X11R6
# make clean # make # mkdir tmp # cd tmp # ar x ../libdb.a # ld -b -o libdb-3.2.sl *.o # mv libdb-3.2.sl /usr/local/lib # rm *.o # cd /usr/local/lib # rm -f libdb.sl # ln -s libdb-3.2.sl libdb.sl
# cd .../DB_File-1.76 # make distclean # perl Makefile.PL # make # make test # make install
As of db-4.2.x it is no longer needed to do this by hand. Sleepycat has changed the configuration process to add +z on HP-UX automatically.
# cd .../db-4.2.25/build_unix # env CFLAGS=+DA2.0w LDFLAGS=+DA2.0w ../dist/configure
should work to generate 64bit shared libraries for HP-UX 11.00 and 11i.
It is no longer possible to link PA-RISC 1.0 shared libraries (even though the command-line flags are still present).
PA-RISC and Itanium object files are not interchangeable. Although you may be able to use ar to create an archive library of PA-RISC object files on an Itanium system, you cannot link against it using an Itanium link editor.
Above mentioned distributions are depots. H.Merijn Brand has made prebuilt gcc binaries available on http://mirrors.develooper.com/hpux/ and/or http://www.cmve.net/~merijn/ for HP-UX 10.20, HP-UX 11.00, and HP-UX 11.11 (HP-UX 11i) in both 32- and 64-bit versions. These are bzipped tar archives that also include recent GNU binutils and GNU gdb. Read the instructions on that page to rebuild gcc using itself.
On PA-RISC you need a different compiler for 32-bit applications and for 64-bit applications. On PA-RISC, 32-bit objects and 64-bit objects do not mix. Period. There is no different behaviour for HP C-ANSI-C or GNU gcc. So if you require your perl binary to use 64-bit libraries, like Oracle-64bit, you MUST build a 64-bit perl.
Building a 64-bit capable gcc on PA-RISC from source is possible only when you have the HP C-ANSI C compiler or an already working 64-bit binary of gcc available. Best performance for perl is achieved with HP's native compiler.
There are some drawbacks to this approach. One is that any extension which calls any file-manipulating C function will need to be recompiled (just follow the usual ``perl Makefile.PL; make; make test; make install'' procedure).
The list of functions that will need to recompiled is:
creat, fgetpos, fopen,
freopen, fsetpos, fstat,
fstatvfs, fstatvfsdev, ftruncate,
ftw, lockf, lseek,
lstat, mmap, nftw,
open, prealloc, stat,
statvfs, statvfsdev, tmpfile,
truncate, getrlimit, setrlimit
Another drawback is only valid for Perl versions before 5.6.0. This drawback is that the seek and tell functions (both the builtin version and POSIX module version) will not perform correctly.
It is strongly recommended that you use this flag when you run Configure. If you do not do this, but later answer the question about large files when Configure asks you, you may get a configuration that cannot be compiled, or that does not function as expected.
To compile Perl with threads, add -Dusethreads to the arguments of Configure. Verify that the -D_POSIX_C_SOURCE=199506L compiler flag is automatically added to the list of flags. Also make sure that -lpthread is listed before -lc in the list of libraries to link Perl with. The hints provided for HP-UX during Configure will try very hard to get this right for you.
HP-UX versions before 10.30 require a separate installation of a POSIX threads library package. Two examples are the HP DCE package, available on ``HP-UX Hardware Extensions 3.0, Install and Core OS, Release 10.20, April 1999 (B3920-13941)'' or the Freely available PTH package, available on H.Merijn's site (http://mirrors.develooper.com/hpux/).
If you are going to use the HP DCE package, the library used for threading is /usr/lib/libcma.sl, but there have been multiple updates of that library over time. Perl will build with the first version, but it will not pass the test suite. Older Oracle versions might be a compelling reason not to update that library, otherwise please find a newer version in one of the following patches: PHSS_19739, PHSS_20608, or PHSS_23672
d3:/usr/lib 106 > what libcma-*.1 libcma-00000.1: HP DCE/9000 1.5 Module: libcma.sl (Export) Date: Apr 29 1996 22:11:24 libcma-19739.1: HP DCE/9000 1.5 PHSS_19739-40 Module: libcma.sl (Export) Date: Sep 4 1999 01:59:07 libcma-20608.1: HP DCE/9000 1.5 PHSS_20608 Module: libcma.1 (Export) Date: Dec 8 1999 18:41:23 libcma-23672.1: HP DCE/9000 1.5 PHSS_23672 Module: libcma.1 (Export) Date: Apr 9 2001 10:01:06 d3:/usr/lib 107 >
If you choose for the PTH package, use swinstall to install pth in the default location (/opt/pth), and then make symbolic links to the libraries from /usr/lib
# cd /usr/lib # ln -s /opt/pth/lib/libpth* .
For building perl to support Oracle, it needs to be linked with libcl and libpthread. So even if your perl is an unthreaded build, these libraries might be required. See ``Oracle on HP-UX'' below.
As of the date of this document, Perl is fully 64-bit compliant on HP-UX 11.00 and up for both cc- and gcc builds. If you are about to build a 64-bit perl with GNU gcc, please read the gcc section carefully.
Should a user have the need for compiling Perl in the LP64 environment, use the -Duse64bitall flag to Configure. This will force Perl to be compiled in a pure LP64 environment (with the +DD64 flag for HP C-ANSI-C, with no additional options for GNU gcc 64-bit on PA-RISC, and with -mlp64 for GNU gcc on Itanium). If you want to compile Perl using gcc, you will have to get a version of the compiler that supports 64-bit operations.)
You can also use the -Duse64bitint flag to Configure. Although there are some minor differences between compiling Perl with this flag versus the -Duse64bitall flag, they should not be noticeable from a Perl user's perspective. When configuring -Duse64bitint using a 64bit gcc on a pa-risc architecture, -Duse64bitint is silently promoted to -Duse64bitall.
In both cases, it is strongly recommended that you use these flags when you run Configure. If you do not use do this, but later answer the questions about 64-bit numbers when Configure asks you, you may get a configuration that cannot be compiled, or that does not function as expected.
Configure -A prepend:libswanted='cl pthread ' ...
Do not forget the space before the trailing quote.
Also note that this does not (yet) work with all configurations, it is known to fail with 64-bit versions of GCC.
will turn into illegal code
The workaround is to use some other quoting separator than "/", like for example "!":
When using the GUI version of SAM, click on the Kernel Configuration icon, then the Configurable Parameters icon. Scroll down and select the maxdsiz line. From the Actions menu, select the Modify Configurable Parameter item. Insert the new formula into the Formula/Value box. Then follow the instructions to rebuild your kernel and reboot your system.
In general, a value of 256MB (or ``256*1024*1024'') is sufficient for Perl to compile at maximum optimization.

The key here is the "nss_delete" call. One workaround for this bug seems to be to create add to the file /etc/nsswitch.conf (at least) the following lines
group: files passwd: files
Whether you are using NIS does not matter. Amazingly enough, the same bug also affects Solaris.
With much assistance regarding shared libraries from Marc Sabatella.
