(HP-UX) that will affect how Perl version 5 (hereafter just Perl) is
compiled and/or runs.
+=head2 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
+
+The 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 Perl will be installed
+automatically.
+
+More recent (preinstalled) HP-UX systems have more recent versions of
+Perl and the updated modules.
+
+=head2 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.
+
=head2 Compiling Perl 5 on HP-UX
When compiling Perl, you must use an ANSI C compiler. The C compiler
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 README file for more gcc-specific
+complete, and be sure to read the Perl INSTALL file for more gcc-specific
details.

+
+A complete list of models at the time the OS was built is in the file

+=head2 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

+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 \

- # mkdir tmp
- # cd tmp
- # ar x ../libdb.a
- # ld -b -o libdb-3.2.sl *.o

- # rm -f libdb.sl
- # ln -s libdb-3.2.sl libdb.sl
-
- # cd .../DB_File-1.76
- # make distclean
- # perl Makefile.PL
- # make

+ # cd .../DB_File-1.76
+ # make distclean
+ # perl Makefile.PL
+ # make
+ # make test

+
+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.

recent version of the Perl distribution, these flags are set automatically.
-=head2 Using Large Files with Perl
+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 from 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. There are two places where
+gcc prebuilds can be fetched; the first and best (for HP-UX 11 only) is
+http://h21007.www2.hp.com/dspp/tech/tech_TechSoftwareDetailPage_IDX/1,1703,547,00.html
+the second is http://hpux.cs.utah.edu/hppd/hpux/Gnu/ where you can also
+find the GNU binutils package. (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, and HP-UX 11.11
+(HP-UX 11i) 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.

+=head2 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
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
large files when Configure asks you, you may get a configuration that
cannot be compiled, or that does not function as expected.

+=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
+
+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.
-=head2 GDBM and Threads
+Also note that this does not (yet) work with all configurations,
+it is known to fail with 64-bit versions of GCC.
+
+=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)
+=head2 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.

+If HP-UX Perl is compiled with flags that will cause problems if the
-P flag of Perl (preprocess Perl code with the C preprocessor before
perl sees it) is used. The problem is that C<//>, being a C++-style
until-end-of-line comment, will disappear along with the remainder
of the line. This means that common Perl constructs like
- s/foo//;
+ s/foo//;
will turn into illegal code
- s/foo
+ s/foo
The workaround is to use some other quoting separator than C<"/">,
like for example C<"!">:
- s!foo!!;
+ s!foo!!;
-=head2 Kernel parameters (maxdsiz)
+=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
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
+ #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 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,
+the same bug also affects Solaris.
