+=head2 Itanium Processor Family and HP-UX
+
+HP-UX also runs on the new Itanium processor. This requires the use
+of a different version of HP-UX (currently 11.20), 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.
=head2 Building Dynamic Extensions on HP-UX
HP-UX supports dynamically loadable libraries (shared libraries).
-Shared libraries end with the suffix .sl.
+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
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
Note that it is okay to create a library which contains a dependent
library that is already linked into perl.
-It is no longer possible to link PA-RISC 1.0 shared libraries.
+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 and address it at
+ http://devresource.hp.com/devresource/Docs/TechTips/cxxTips.html#tip13
+
+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
+
+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.

HP-UX versions before 10.30 require a seperate installation of a POSIX
threads library package. Two examples are the HP DCE package, available
though worldwide HP-UX mirrors of precompiled packages
(e.g. http://hpux.tn.tudelft.nl/hppd/hpux/alpha.html)

+=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
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 GDBM and Threads
+=head2 GDBM and Threads on HP-UX
If you attempt to compile Perl with 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.

+=head2 NFS filesystems and utime(2) on HP-UX

+=head2 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.
+
+=head1 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

+ #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 C<nss_delete> call. One workaround for this
+bug seems to be to create add to the file F</etc/nsswitch.conf>
+(at least) the following lines
+
+ group: files
+ passwd: files
+
+Whether you are using NIS does not matter. Amazingly enough,
