but the resulting executable will not run when transferred to a PA-RISC
1.0 system.

+=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
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.
-=head2 Using Large Files with Perl
+=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
large files when Configure asks you, you may get a configuration that
cannot be compiled, or that does not function as expected.
-=head2 Threaded Perl
+=head2 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
though worldwide HP-UX mirrors of precompiled packages
(e.g. http://hpux.tn.tudelft.nl/hppd/hpux/alpha.html)
-=head2 64-bit Perl
+=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)
+=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.

+=head2 perl -P and // and HP-UX
In HP-UX Perl is compiled with flags that will cause problems if the

-=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 affects also Solaris.
