       perlhpux - Perl version 5 on Hewlett-Packard Unix (HP-UX) systems

       This document describes various features of HP's Unix operating system (HP-UX) that will
       affect how Perl version 5 (hereafter just Perl) is compiled and/or runs.

   Using perl as shipped with HP-UX
       Application release September 2001, HP-UX 11.00 is the first to ship with Perl. By the
       time it was perl-5.6.1 in /opt/perl. The first occurrence is on CD 5012-7954 and can be
       installed using

         swinstall -s /cdrom perl

       assuming you have mounted that CD on /cdrom.

       That 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 (a newer) Perl will be installed automatically.
       Pre-installed HP-UX systems now have more recent versions of Perl and the updated modules.

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

       To see what version is included on the DVD (assumed here to be mounted on /cdrom), issue
       this command:

         # swlist -s /cdrom perl
         # perl           D.5.8.8.B  5.8.8 Perl Programming Language
           perl.Perl5-32  D.5.8.8.B  32-bit 5.8.8 Perl Programming Language with Extensions
           perl.Perl5-64  D.5.8.8.B  64-bit 5.8.8 Perl Programming Language with Extensions

       To see what is installed on your system:

         # swlist -R perl
         # perl                    E.5.8.8.J  Perl Programming Language
         # perl.Perl5-32           E.5.8.8.J  32-bit Perl Programming Language with Extensions
           perl.Perl5-32.PERL-MAN  E.5.8.8.J  32-bit Perl Man Pages for IA
           perl.Perl5-32.PERL-RUN  E.5.8.8.J  32-bit Perl Binaries for IA
         # perl.Perl5-64           E.5.8.8.J  64-bit Perl Programming Language with Extensions
           perl.Perl5-64.PERL-MAN  E.5.8.8.J  64-bit Perl Man Pages for IA
           perl.Perl5-64.PERL-RUN  E.5.8.8.J  64-bit Perl Binaries for IA

   Using perl from HP's porting centre
       HP porting centre tries to keep up with customer demand and release updates from the Open
       Source community. Having precompiled Perl binaries available is obvious, though "up-to-
       date" is something relative. At the moment of writing only perl-5.10.1 was available (with
       5.16.3 being the latest stable release from the porters point of view).

       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.

       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.

   Other prebuilt perl binaries
       To get even more recent perl depots for the whole range of HP-UX, visit H.Merijn Brand's
       site at <http://mirrors.develooper.com/hpux/#Perl>.  Carefully read the notes to see if
       the available versions suit your needs.

   Compiling Perl 5 on HP-UX
       When compiling Perl, you must use an ANSI C compiler.  The C compiler that ships with all
       HP-UX systems is a K&R compiler that should only be used to build new kernels.

       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.

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

       The version of PA-RISC at the time of this document's last update is 2.0, which is also
       the last there will be. HP PA-RISC systems are usually refered to with model description
       "HP 9000". The last CPU in this series is the PA-8900.  Support for PA-RISC architectured
       machines officially ends as shown in the following table:

       From <http://www.hp.com/products1/evolution/9000/faqs.html>

        The last order date for HP 9000 systems was December 31, 2008.

       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
         # grep L1000-44 /usr/sam/lib/mo/sched.models
         L1000-44        2.0     PA8500

   Portability Between PA-RISC Versions
       An executable compiled on a PA-RISC 2.0 platform will not execute on a PA-RISC 1.1
       platform, even if they are running the same version of HP-UX.  If you are building Perl on
       a PA-RISC 2.0 platform and want that Perl to also run on a PA-RISC 1.1, the compiler flags
       +DAportable and +DS32 should be used.

       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.

   PA-RISC 1.0
       The original version of PA-RISC, HP no longer sells any system with this chip.

       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

   PA-RISC 1.1
       An upgrade to the PA-RISC design, it shipped for many years in many different system.

       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,

   PA-RISC 2.0
       The most recent upgrade to the PA-RISC design, it added support for 64-bit integer data.

       As of the date of this document's last update, the following systems contain PA-RISC 2.0

         700, 780, 781, 782, 783, 785, 802, 804, 810, 820, 861, 871, 879, 889,

         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, rp7440, rp8400, rp8420, rp8440, Superdome

       The current naming convention is:

         ||||`+- 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

   Itanium Processor Family (IPF) and HP-UX
       HP-UX also runs on the new Itanium processor.  This requires the use of a different
       version of HP-UX (currently 11.23 or 11i v2), and with the exception of a few differences
       detailed below and in later sections, Perl should compile with no problems.

       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".

   Itanium, Itanium 2 & Madison 6
       HP also ships servers with the 128-bit Itanium processor(s). The cx26x0 is told to have
       Madison 6. As of the date of this document's last update, the following systems contain
       Itanium or Itanium 2 chips (this is likely to be out of date):

         BL60p, BL860c, BL870c, BL890c, cx2600, cx2620, rx1600, rx1620, rx2600,
         rx2600hptc, rx2620, rx2660, rx2800, rx3600, rx4610, rx4640, rx5670,
         rx6600, rx7420, rx7620, rx7640, rx8420, rx8620, rx8640, rx9610,
         sx1000, sx2000

       To see all about your machine, type

         # model
         ia64 hp server rx2600
         # /usr/contrib/bin/machinfo

   HP-UX versions
       Not all architectures (PA = PA-RISC, IPF = Itanium Processor Family) support all versions
       of HP-UX, here is a short list

         HP-UX version  Kernel  Architecture End-of-factory support
         -------------  ------  ------------ ----------------------------------

   Building Dynamic Extensions on HP-UX
       HP-UX supports dynamically loadable libraries (shared libraries).  Shared libraries end
       with the suffix .sl.  On Itanium systems, they end with the suffix .so.

       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

       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.

   The HP ANSI C Compiler
       When using this compiler to build Perl, you should make sure that the flag -Aa is added to
       the cpprun and cppstdin variables in the config.sh file (though see the section on 64-bit
       perl below). If you are using a recent version of the Perl distribution, these flags are
       set automatically.

       Even though HP-UX 10.20 and 11.00 are not actively maintained by HP anymore, updates for
       the HP ANSI C compiler are still available from time to time, and it might be advisable to
       see if updates are applicable.  At the moment of writing, the latests available patches
       for 11.00 that should be applied are PHSS_35098, PHSS_35175, PHSS_35100, PHSS_33036, and
       PHSS_33902). If you have a SUM account, you can use it to search for updates/patches.
       Enter "ANSI" as keyword.

   The GNU C Compiler
       When you are going to use the GNU C compiler (gcc), and you don't have gcc yet, you can
       either build it yourself from the sources (available from e.g.
       <http://gcc.gnu.org/mirrors.html>) or fetch a prebuilt binary from the HP porting center
       at <http://hpux.connect.org.uk/hppd/cgi-bin/search?term=gcc&Search=Search> or from the
       DSPP (you need to be a member) at
       (Browse through the list, because there are often multiple versions of the same package

       Most 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 (only 32bit), HP-UX 11.00, HP-UX 11.11 (HP-UX 11i v1), and HP-UX 11.23
       (HP-UX 11i v2 PA-RISC) in both 32- and 64-bit versions. For HP-UX 11.23 IPF and HP-UX
       11.31 IPF depots are available too. The IPF versions do not need two versions of GNU gcc.

       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.

   Using Large Files with Perl on HP-UX
       Beginning with HP-UX version 10.20, files larger than 2GB (2^31 bytes) may be created and
       manipulated.  Three separate methods of doing this are available.  Of these methods, the
       best method for Perl is to compile using the -Duselargefiles flag to Configure.  This
       causes Perl to be compiled using structures and functions in which these are 64 bits wide,
       rather than 32 bits wide.  (Note that this will only work with HP's ANSI C compiler.  If
       you want to compile Perl using gcc, you will have to get a version of the compiler that
       supports 64-bit operations. See above for where to find it.)

       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.

   Threaded Perl on HP-UX
       It is possible to compile a version of threaded Perl on any version of HP-UX before 10.30,
       but it is strongly suggested that you be running on HP-UX 11.00 at least.

       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/>). The use of
       PTH will be unsupported in perl-5.12 and up and is rather buggy in 5.11.x.

       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

       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.

   64-bit Perl on HP-UX
       Beginning with HP-UX 11.00, programs compiled under HP-UX can take advantage of the LP64
       programming environment (LP64 means Longs and Pointers are 64 bits wide), in which scalar
       variables will be able to hold numbers larger than 2^32 with complete precision.  Perl has
       proven to be consistent and reliable in 64bit mode since 5.8.1 on all HP-UX 11.xx.

       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

       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

       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.

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

         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.

   GDBM and Threads on HP-UX
       If you attempt to compile Perl with (POSIX) threads on an 11.X system and also link in the
       GDBM library, then Perl will immediately core dump when it starts up.  The only workaround
       at this point is to relink the GDBM library under 11.X, then relink it into Perl.

       the error might show something like:

       Pthread internal error: message: __libc_reinit() failed, file: ../pthreads/pthread.c,
       line: 1096 Return Pointer is 0xc082bf33 sh: 5345 Quit(coredump)

       and Configure will give up.

   NFS filesystems and utime(2) on HP-UX
       If you are compiling Perl on a remotely-mounted NFS filesystem, the test io/fs.t may fail
       on test #18.  This appears to be a bug in HP-UX and no fix is currently available.

   HP-UX Kernel Parameters (maxdsiz) for Compiling Perl
       By default, HP-UX comes configured with a maximum data segment size of 64MB.  This is too
       small to correctly compile Perl with the maximum optimization levels.  You can increase
       the size of the maxdsiz kernel parameter through the use of SAM.

       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

       In general, a value of 256MB (or "256*1024*1024") is sufficient for Perl to compile at
       maximum optimization.

nss_delete core dump from op/pwent or op/grent
       You may get a bus error core dump from the op/pwent or op/grent tests. If compiled with -g
       you will see a stack trace much like the following:

         #0  0xc004216c in  () from /usr/lib/libc.2
         #1  0xc00d7550 in __nss_src_state_destr () from /usr/lib/libc.2
         #2  0xc00d7768 in __nss_src_state_destr () from /usr/lib/libc.2
         #3  0xc00d78a8 in nss_delete () from /usr/lib/libc.2
         #4  0xc01126d8 in endpwent () from /usr/lib/libc.2
         #5  0xd1950 in Perl_pp_epwent () from ./perl
         #6  0x94d3c in Perl_runops_standard () from ./perl
         #7  0x23728 in S_run_body () from ./perl
         #8  0x23428 in perl_run () from ./perl
         #9  0x2005c in main () from ./perl

       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

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