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.
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

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 perl-5.10.1 and 5.28.0 were available.
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. As porting modern GNU gcc is extremely hard on HP-UX, they are stuck at version gcc-4.2.3.
Other prebuilt perl binaries
To get more 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.
PA-RISC
The last and final version of PA-RISC is 2.0, HP no longer sells any system with these CPU's.
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. Even though PA-
RISC hardware is not sold anymore, a lot of machines still running on these CPU's can be found in the
wild.
The last order date for HP 9000 systems was December 31, 2008.
HP PA-RISC systems are usually referred to with model description "HP 9000". The last CPU in this series
is the PA-8900. Support for PA-RISC architectured machines officially ended as shown in the following

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.

rp7410, rp7420, rp7440, rp8400, rp8420, rp8440, Superdome
The current naming convention is:

b = blade
sa = appliance
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.
Itanium Processor Family (IPF) and HP-UX
HP-UX also runs on the newer Itanium processor. This requires the use of HP-UX version 11.23 (11i v2) or
11.31 (11i v3), 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 referred 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,

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
# 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).
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 (if you feel masochistic enough) 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
<http://h21007.www2.hp.com/portal/site/dspp/menuitem.863c3e4cbcdc3f3515b49c108973a801?ciid=2a08725cc2f02110725cc2f02110275d6e10RCRD&jumpid=reg_r1002_usen_c-001_title_r0001>
(Browse through the list, because there are often multiple versions of the same package available).
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 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.
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 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

#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 Solaris.
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:
--- /usr/include/inttypes.h 2001-04-20 18:42:14 +0200
+++ /usr/include/inttypes.h 2000-11-14 09:00:00 +0200

Redeclaration of "sendpath" with a different storage class specifier
The following compilation warnings may happen in HP-UX releases earlier than 11.31 but are harmless:
cc: "/usr/include/sys/socket.h", line 535: warning 562:
Redeclaration of "sendfile" with a different storage class
specifier: "sendfile" will have internal linkage.
cc: "/usr/include/sys/socket.h", line 536: warning 562:
Redeclaration of "sendpath" with a different storage class
specifier: "sendpath" will have internal linkage.
They seem to be caused by broken system header files, and also other open source projects are seeing
them. The following HP-UX patches should make the warnings go away:
CR JAGae12001: PHNE_27063
Warning 562 on sys/socket.h due to redeclaration of prototypes
CR JAGae16787:

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.
