PERLHPUX(1)                                Perl Programmers Reference Guide                               PERLHPUX(1)



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

DESCRIPTION
       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. 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

       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.  Preinstalled HP-UX
       systems now slao 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

   Using perl from HP's porting centre
       HP porting centre tries very hard to keep up with customer demand and release updates from the Open Source
       community. Having precompiled Perl binaries available is obvious.

       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.

       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
         9000/800/L1000-44
         # 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.

   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 chips:

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

       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:

         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


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

   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
         -------------  ------  ------------
         10.20          32 bit  PA

   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.


       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=+DD64 LDFLAGS=+DD64 ../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).

       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. gcc prebuilds can be fetched from
       <http://h21007.www2.hp.com/dspp/tech/tech_TechSoftwareDetailPage_IDX/1,1703,547,00.html> (Browse through the
       list, because there are often multiple versions of the same package available).

       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, HP-
       UX 11.11 (HP-UX 11i v1), and HP-UX 11.23 (HP-UX 11i v2) 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.

   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.

       (<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
       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.


       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 system.

       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
         #else /* __LP64 */
         #define INT32_C(__c)                    __CONCAT__(__c,l)
        -#define UINT32_C(__c)                   __CONCAT__(__CONCAT_U__(__c),l)
        +#define UINT32_C(__c)                   __CONCAT__(__c,ul)
         #endif /* __LP64 */

         #define INT64_C(__c)                    __CONCAT_L__(__c,l)

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