=head1 Start with a Fresh Distribution
the default directory for architecture-dependent library modules
includes the version name. By default, Configure will reuse your old
name (e.g. /opt/perl/lib/i86pc-solaris/5.003) even if you're running
-Configure for a different version, e.g. 5.004. Yes, Configure should
-probably check and correct for this, but it doesn't. Similarly, if you
-used a shared libperl.so (see below) with version numbers, you will
-probably want to adjust them as well.

Also, be careful to check your architecture name. For example, some
-Linux distributions use i386, while others may use i486. If you build

+Linux distributions use i386, but Configure uses the output of the arch
+command, which might be i686 instead. If you pick up a precompiled
+binary, or compile extensions on different systems, they might not all
+agree on the architecture name.
In short, if you wish to use your old config.sh, I recommend running
Configure interactively rather than blindly accepting the defaults.
For example, here's how to add a couple of extra flags to C compiler
invocations:
- sh Configure -Accflags="-DPERL_Y2KWARN -DPERL_POLLUTE_MALLOC"
+ sh Configure -Accflags="-DPERL_EXTERNAL_GLOB -DPERL_POLLUTE_MALLOC"
+
+To clarify, those ccflags values are not Configure options; if passed to
+Configure directly, they won't do anything useful (that will define a config.sh
+variable, but without taking any action based upon it). When passed to the
+compiler, those flags will activate #ifdefd code.
For more help on Configure switches, run
or interactively at the appropriate Configure prompt.
-With the PerlIO abstraction layer, there is another possibility for
-the underlying IO calls, AT&T's "sfio". This has superior performance
-to stdio.h in many cases, and is extensible by the use of "discipline"
-modules ("Native" PerlIO has them too). Sfio currently only builds on
-a subset of the UNIX platforms perl supports. Because the data
-structures are completely different from stdio, perl extension modules
-or external libraries may not work. This configuration exists to

-
-This option requires the 'sfio' package to have been built and installed.
-The latest sfio is available from http://www.research.att.com/sw/tools/sfio/
-
-You select this option by
-
- sh Configure -Duseperlio -Dusesfio
-
-If you have already selected -Duseperlio, and if Configure detects
-that you have sfio, then sfio will be the default suggested by
-Configure.
-
-Note: On some systems, sfio's iffe configuration script fails to
-detect that you have an atexit function (or equivalent). Apparently,
-this is a problem at least for some versions of Linux and SunOS 4.
-Configure should detect this problem and warn you about problems with

=head3 Algorithmic Complexity Attacks on Hashes
In Perls 5.8.0 and earlier it was easy to create degenerate hashes.
Currently, for most systems, the main perl executable is built by
linking the "perl library" libperl.a with perlmain.o, your static

On some systems that support dynamic loading, it may be possible to
replace libperl.a with a shared libperl.so. If you anticipate building
whenever perl is running as a stand alone interpreter, and to call the safe
but potentially leaky C<putenv()> function when the perl interpreter is
embedded in another application. You can force perl to always use C<putenv()>

-In versions 5.005_57 and earlier, the default was to store module man
-pages in a version-specific directory, such as
-/usr/local/lib/perl5/$version/man/man3. The default for 5.005_58 and
-after is /usr/local/man/man3 so that most users can find the man pages
-without resetting MANPATH.
-
-You can continue to use the old default from the command line with
-
- sh Configure -Dman3dir=/usr/local/lib/perl5/5.9.0/man/man3

-Some users also prefer to use a .3pm suffix. You can do that with

Currently, the standard perl installation does not do anything with
management software to move perl to its final destination. This
section describes how to do that.

=item Hint files
-The perl distribution includes a number of system-specific hints files

+Hint files tell Configure about a number of things:

+
+The peculiarities or conventions of particular platforms -- non-standard
+library locations and names, default installation locations for binaries,
+and so on.

+The deficiencies of the platform -- for example, library functions that,
+although present, are too badly broken to be usable; or limits on
+resources that are generously available on most platforms.
+
+=item o
+
+How best to optimize for the platform, both in terms of binary size and/or
+speed, and for Perl feature support. Because of wide variations in the
+implementation of shared libraries and of threading, for example, Configure
+often needs hints in order to be able to use these features.
+
+=back
+
+The perl distribution includes many system-specific hints files
+in the hints/ directory. If one of them matches your system, Configure
+will offer to use that hint file. Unless you have a very good reason
+not to, you should accept its offer.
Several of the hint files contain additional important information.
If you have any problems, it is a good idea to read the relevant hint file
for further information. See hints/solaris_2.sh for an extensive example.
More information about writing good hints is in the hints/README.hints

-=item *** WHOA THERE!!! ***
-
-Occasionally, Configure makes a wrong guess. For example, on SunOS
-4.1.3, Configure incorrectly concludes that tzname[] is in the
-standard C library. The hint file is set up to correct for this. You
-will see a message:
+file, which also explains hint files known as callback-units.
- *** WHOA THERE!!! ***
- The recommended value for $d_tzname on this machine was "undef"!
- Keep the recommended value? [y]
+Note that any hint file is read before any Policy file, meaning that
+Policy overrides hints -- see L</Site-wide Policy settings>.
-You should always keep the recommended value unless, after reading the
-relevant section of the hint file, you are sure you want to try
-overriding it.
+=item *** WHOA THERE!!! ***
-If you are re-using an old config.sh, the word "previous" will be
-used instead of "recommended". Again, you will almost always want
-to keep the previous value, unless you have changed something on your

+If you are re-using an old config.sh, it's possible that Configure detects
+different values from the ones specified in this file. You will almost

=head2 Cross-compilation
-Starting from version 5.8, Perl has the beginnings of cross-compilation
-support. What is known to work is running Configure in a
-cross-compilation environment and building the miniperl executable.
-What is known not to work is building the perl executable because
-that would require building extensions: Dynaloader statically and
-File::Glob dynamically, for extensions one needs MakeMaker and
-MakeMaker is not yet cross-compilation aware, and neither is
-the main Makefile.
-
-Since the functionality is so lacking, it must be considered
-highly experimental. It is so experimental that it is not even
-mentioned during an interactive Configure session, a direct command
-line invocation (detailed shortly) is required to access the
-functionality.
-
- NOTE: Perl is routinely built using cross-compilation
- in the EPOC environment, in the WinCE, and in the OpenZaurus
- project, but all those use something slightly different setup
- than what described here. For the WinCE setup, read the
- wince/README.compile. For the OpenZaurus setup, read the
- Cross/README.
-
-The one environment where this cross-compilation setup has
-successfully been used as of this writing is the Compaq iPAQ running
-ARM Linux. The build host was Intel Linux, the networking setup was
-PPP + SSH. The exact setup details are beyond the scope of this
-document, see http://www.handhelds.org/ for more information.
-
-To run Configure in cross-compilation mode the basic switch is
-C<-Dusecrosscompile>.
+Perl can be cross-compiled. It is just not trivial, cross-compilation
+rarely is. Perl is routinely cross-compiled for many platforms (as of
+June 2005 at least PocketPC aka WinCE, Open Zaurus, EPOC, Symbian, and
+the IBM OS/400). These platforms are known as the B<target> platforms,
+while the systems where the compilation takes place are the B<host>
+platforms.
+
+What makes the situation difficult is that first of all,
+cross-compilation environments vary significantly in how they are set
+up and used, and secondly because the primary way of configuring Perl
+(using the rather large Unix-tool-dependent Configure script) is not
+awfully well suited for cross-compilation. However, starting from
+version 5.8.0, the Configure script also knows one way of supporting
+cross-compilation support, please keep reading.

+Packaging and transferring either the core Perl modules or CPAN
+modules to the target platform is also left up to the each

+platforms are somewhat limited in diskspace: see the section
+L<Minimizing the Perl installation> to learn more of the minimal set
+of files required for a functional Perl installation.

+A nice trick to find out the minimal set of Perl library files you will
+need to run a Perl program is
+
+ perl -e 'do "prog.pl"; END { print "$_\n" for sort keys %INC }'
+
+(this will not find libraries required in runtime, unfortunately, but
+it's a minimal set) and if you want to find out all the files you can
+use something like the below
+
+ strace perl -le 'do "x.pl"' 2>&1 | perl -nle '/^open\(\"(.+?)"/ && print $1'
+
+(The 'strace' is Linux-specific, other similar utilities include 'truss'
+and 'ktrace'.)
