+The official (threaded) builds from HP, as they are shipped on the
+Application DVD/CD's are available on
+L<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.

+=head2 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 L<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.
+
+=head2 Other prebuilt perl binaries
+
+To get more perl depots for the whole range of HP-UX, visit
+H.Merijn Brand's site at L<http://mirrors.develooper.com/hpux/#Perl>.
+Carefully read the notes to see if the available versions suit your needs.

details.
=head2 PA-RISC
-HP's current Unix systems run on its own Precision Architecture
+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.
+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 table:

=head2 Building Dynamic Extensions on HP-UX
HP-UX supports dynamically loadable libraries (shared libraries).
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.
+ 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.
+ 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).
HP is aware of this problem. Search the HP-UX cxx-dev forums for
discussions about the subject. The short answer is that B<everything>
(all libraries, everything) must be compiled with C<+z> or C<+Z> to be
-PIC (position independent code). In HP-UX 11.00 or newer the linker
+PIC (position independent code). (For gcc, that would be
+C<-fpic> or C<-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
+ # 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

It is no longer possible to link PA-RISC 1.0 shared libraries (even
though the command-line flags are still present).
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.

+=head2 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)

+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.

=head2 Using Large Files with Perl on HP-UX
Beginning with HP-UX version 10.20, files larger than 2GB (2^31 bytes)
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 support 64-bit operations.)
+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
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
+ creat, fgetpos, fopen,

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
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

-(e.g. http://hpux.tn.tudelft.nl/hppd/hpux/)
+on H.Merijn's site (L<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
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.
=head2 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).
-
-Work is being performed on Perl to make it 64-bit compliant on all
-versions of Unix. Once this is complete, scalar variables will be able
-to hold numbers larger than 2^32 with complete precision.
-
-As of the date of this document, Perl is not 64-bit compliant on HP-UX.
-
-Should a user wish to experiment with compiling Perl in the LP64
-environment, use the -Duse64bitall flag to Configure. This will force
-Perl to be compiled in a pure LP64 environment (via the +DD64 flag).
+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.
+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
configuration that cannot be compiled, or that does not function as
expected.
-(Note that these Configure flags 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 support 64-bit operations.)
+=head2 Oracle on HP-UX
-=head2 GDBM and Threads 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

+achieved using
