NAME
README.hpux - 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.
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
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:

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

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

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):

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
perl v5.12.5 Last change: 2012-11-03 6
Perl Programmers Reference Guide PERLHPUX(1)
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
perl v5.12.5 Last change: 2012-11-03 7
Perl Programmers Reference Guide PERLHPUX(1)
# 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 from
perl v5.12.5 Last change: 2012-11-03 8
Perl Programmers Reference Guide PERLHPUX(1)
the sources (available from e.g.
http://www.gnu.ai.mit.edu/software/gcc/releases.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,
perl v5.12.5 Last change: 2012-11-03 9
Perl Programmers Reference Guide PERLHPUX(1)
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
perl v5.12.5 Last change: 2012-11-03 12
Perl Programmers Reference Guide PERLHPUX(1)
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
Whether you are using NIS does not matter. Amazingly
enough, the same bug also affects Solaris.
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.
