NAME
       perlsolaris - Perl version 5 on Solaris systems

DESCRIPTION
       This document describes various features	of Sun's Solaris operating
       system that will	affect how Perl	version	5 (hereafter just perl)	is
       compiled	and/or runs.  Some issues relating to the older	SunOS 4.x are
       also discussed, though they may be out of date.

       For the most part, everything should just work.

       Starting	with Solaris 8,	perl5.00503 (or	higher)	is supplied with the
       operating system, so you	might not even need to build a newer version
       of perl at all.	The Sun-supplied version is installed in /usr/perl5
       with /usr/bin/perl pointing to /usr/perl5/bin/perl.  Do not disturb
       that installation unless	you really know	what you are doing.  If	you
       remove the perl supplied	with the OS, you will render some bits of your
       system inoperable.  If you wish to install a newer version of perl,
       install it under	a different prefix from	/usr/perl5.  Common prefixes
       to use are /usr/local and /opt/perl.

       You may wish to put your	version	of perl	in the PATH of all users by
       changing	the link /usr/bin/perl.	 This is probably OK, as most perl
       scripts shipped with Solaris use	an explicit path.  (There are a	few
       exceptions, such	as /usr/bin/rpm2cpio and /etc/rcm/scripts/README, but
       these are also sufficiently generic that	the actual version of perl
       probably	doesn't	matter too much.)

       Solaris ships with a range of Solaris-specific modules.	If you choose
       to install your own version of perl you will find the source of many of
       these modules is	available on CPAN under	the Sun::Solaris:: namespace.

       Solaris may include two versions	of perl, e.g. Solaris 9	includes both
       5.005_03	and 5.6.1.  This is to provide stability across	Solaris
       releases, in cases where	a later	perl version has incompatibilities
       with the	version	included in the	preceding Solaris release.  The
       default perl version will always	be the most recent, and	in general the
       old version will	only be	retained for one Solaris release.  Note	also
       that the	default	perl will NOT be configured to search for modules in
       the older version, again	due to compatibility/stability concerns.  As a
       consequence if you upgrade Solaris, you will have to rebuild/reinstall
       any additional CPAN modules that	you installed for the previous Solaris
       version.	 See the CPAN manpage under 'autobundle' for a quick way of
       doing this.

       As an interim measure, you may either change the	#! line	of your
       scripts to specifically refer to	the old	perl version, e.g. on Solaris
       9 use #!/usr/perl5/5.00503/bin/perl to use the perl version that	was
       the default for Solaris 8, or if	you have a large number	of scripts it
       may be more convenient to make the old version of perl the default on
       your system.  You can do	this by	changing the appropriate symlinks
       under /usr/perl5	as follows (example for	Solaris	9):

	# cd /usr/perl5
	# rm bin man pod
	# ln -s	./5.00503/bin
	# ln -s	./5.00503/man
	# ln -s	./5.00503/lib/pod
	# rm /usr/bin/perl
	# ln -s	../perl5/5.00503/bin/perl /usr/bin/perl

       In both cases this should only be considered to be a temporary measure
       - you should upgrade to the later version of perl as soon as is
       practicable.

       Note also that the perl command-line utilities (e.g. perldoc) and any
       that are	added by modules that you install will be under
       /usr/perl5/bin, so that directory should	be added to your PATH.

   Solaris Version Numbers.
       For consistency with common usage, perl's Configure script performs
       some minor manipulations	on the operating system	name and version
       number as reported by uname.  Here's a partial translation table:

		 Sun:			   perl's Configure:
	uname	 uname -r   Name	   osname     osvers
	SunOS	 4.1.3	   Solaris 1.1	   sunos      4.1.3
	SunOS	 5.6	   Solaris 2.6	   solaris    2.6
	SunOS	 5.8	   Solaris 8	   solaris    2.8
	SunOS	 5.9	   Solaris 9	   solaris    2.9
	SunOS	 5.10	   Solaris 10	   solaris    2.10

       The complete table can be found in the Sun Managers' FAQ
       <ftp://ftp.cs.toronto.edu/pub/jdd/sunmanagers/faq> under	"9.1) Which
       Sun models run which versions of	SunOS?".

RESOURCES
       There are many, many sources for	Solaris	information.  A	few of the
       important ones for perl:

       Solaris FAQ
	   The Solaris FAQ is available	at
	   <http://www.science.uva.nl/pub/solaris/solaris2.html>.

	   The Sun Managers' FAQ is available at
	   <ftp://ftp.cs.toronto.edu/pub/jdd/sunmanagers/faq>

       Precompiled Binaries
	   Precompiled binaries, links to many sites, and much,	much more are
	   available at	<http://www.sunfreeware.com/> and
	   <http://www.blastwave.org/>.

       Solaris Documentation
	   All Solaris documentation is	available on-line at
	   <http://docs.sun.com/>.

SETTING	UP
   File	Extraction Problems on Solaris.
       Be sure to use a	tar program compiled under Solaris (not	SunOS 4.x) to
       extract the perl-5.x.x.tar.gz file.  Do not use GNU tar compiled	for
       SunOS4 on Solaris.  (GNU	tar compiled for Solaris should	be fine.)
       When you	run SunOS4 binaries on Solaris,	the run-time system magically
       alters pathnames	matching m#lib/locale# so that when tar	tries to
       create lib/locale.pm, a file named lib/oldlocale.pm gets	created
       instead.	 If you	found this advice too late and used a SunOS4-compiled
       tar anyway, you must find the incorrectly renamed file and move it back
       to lib/locale.pm.

   Compiler and	Related	Tools on Solaris.
       You must	use an ANSI C compiler to build	perl.  Perl can	be compiled
       with either Sun's add-on	C compiler or with gcc.	 The C compiler	that
       shipped with SunOS4 will	not do.

       Include /usr/ccs/bin/ in	your PATH.

       Several tools needed to build perl are located in /usr/ccs/bin/:	 ar,
       as, ld, and make.  Make sure that /usr/ccs/bin/ is in your PATH.

       On all the released versions of Solaris (8, 9 and 10) you need to make
       sure the	following packages are installed (this info is extracted from
       the Solaris FAQ):

       for tools (sccs,	lex, yacc, make, nm, truss, ld,	as): SUNWbtool,
       SUNWsprot, SUNWtoo

       for libraries & headers:	SUNWhea, SUNWarc, SUNWlibm, SUNWlibms,
       SUNWdfbh, SUNWcg6h, SUNWxwinc

       Additionally, on	Solaris	8 and 9	you also need:

       for 64 bit development: SUNWarcx, SUNWbtoox, SUNWdplx, SUNWscpux,
       SUNWsprox, SUNWtoox, SUNWlmsx, SUNWlmx, SUNWlibCx

       And only	on Solaris 8 you also need:

       for libraries & headers:	SUNWolinc

       If you are in doubt which package contains a file you are missing, try
       to find an installation that has	that file. Then	do a

	$ grep /my/missing/file	/var/sadm/install/contents

       This will display a line	like this:

       /usr/include/sys/errno.h	f none 0644 root bin 7471 37605	956241356
       SUNWhea

       The last	item listed (SUNWhea in	this example) is the package you need.

       Avoid /usr/ucb/cc.

       You don't need to have /usr/ucb/	in your	PATH to	build perl.  If	you
       want /usr/ucb/ in your PATH anyway, make	sure that /usr/ucb/ is NOT in
       your PATH before	the directory containing the right C compiler.

       Sun's C Compiler

       If you use Sun's	C compiler, make sure the correct directory (usually
       /opt/SUNWspro/bin/) is in your PATH (before /usr/ucb/).

       GCC

       If you use gcc, make sure your installation is recent and complete.
       perl versions since 5.6.0 build fine with gcc > 2.8.1 on	Solaris	>=
       2.6.

       You must	Configure perl with

	$ sh Configure -Dcc=gcc

       If you don't, you may experience	strange	build errors.

       If you have updated your	Solaris	version, you may also have to update
       your gcc.  For example, if you are running Solaris 2.6 and your gcc is
       installed under /usr/local, check in /usr/local/lib/gcc-lib and make
       sure you	have the appropriate directory,	sparc-sun-solaris2.6/ or
       i386-pc-solaris2.6/.  If	gcc's directory	is for a different version of
       Solaris than you	are running, then you will need	to rebuild gcc for
       your new	version	of Solaris.

       You can get a precompiled version of gcc	from
       <http://www.sunfreeware.com/> or	<http://www.blastwave.org/>. Make sure
       you pick	up the package for your	Solaris	release.

       If you wish to use gcc to build add-on modules for use with the perl
       shipped with Solaris, you should	use the	Solaris::PerlGcc module	which
       is available from CPAN.	The perl shipped with Solaris is configured
       and built with the Sun compilers, and the compiler configuration
       information stored in Config.pm is therefore only relevant to the Sun
       compilers.  The Solaris:PerlGcc module contains a replacement Config.pm
       that is correct for gcc - see the module	for details.

       GNU as and GNU ld

       The following information applies to gcc	version	2.  Volunteers to
       update it as appropriately for gcc version 3 would be appreciated.

       The versions of as and ld supplied with Solaris work fine for building
       perl.  There is normally	no need	to install the GNU versions to compile
       perl.

       If you decide to	ignore this advice and use the GNU versions anyway,
       then be sure that they are relatively recent.  Versions newer than 2.7
       are apparently new enough.  Older versions may have trouble with
       dynamic loading.

       If you wish to use GNU ld, then you need	to pass	it the -Wl,-E flag.
       The hints/solaris_2.sh file tries to do this automatically by setting
       the following Configure variables:

	ccdlflags="$ccdlflags -Wl,-E"
	lddlflags="$lddlflags -Wl,-E -G"

       However,	over the years,	changes	in gcc,	GNU ld,	and Solaris ld have
       made it difficult to automatically detect which ld ultimately gets
       called.	You may	have to	manually edit config.sh	and add	the -Wl,-E
       flags yourself, or else run Configure interactively and add the flags
       at the appropriate prompts.

       If your gcc is configured to use	GNU as and ld but you want to use the
       Solaris ones instead to build perl, then	you'll need to add
       -B/usr/ccs/bin/ to the gcc command line.	 One convenient	way to do that
       is with

	$ sh Configure -Dcc='gcc -B/usr/ccs/bin/'

       Note that the trailing slash is required.  This will result in some
       harmless	warnings as Configure is run:

	gcc: file path prefix `/usr/ccs/bin/' never used

       These messages may safely be ignored.  (Note that for a SunOS4 system,
       you must	use -B/bin/ instead.)

       Alternatively, you can use the GCC_EXEC_PREFIX environment variable to
       ensure that Sun's as and	ld are used.  Consult your gcc documentation
       for further information on the -B option	and the	GCC_EXEC_PREFIX
       variable.

       Sun and GNU make

       The make	under /usr/ccs/bin works fine for building perl.  If you have
       the Sun C compilers, you	will also have a parallel version of make
       (dmake).	 This works fine to build perl,	but can	sometimes cause
       problems	when running 'make test' due to	underspecified dependencies
       between the different test harness files.  The same problem can also
       affect the building of some add-on modules, so in those cases either
       specify '-m serial' on the dmake	command	line, or use /usr/ccs/bin/make
       instead.	 If you	wish to	use GNU	make, be sure that the set-group-id
       bit is not set.	If it is, then arrange your PATH so that
       /usr/ccs/bin/make is before GNU make or else have the system
       administrator disable the set-group-id bit on GNU make.

       Avoid libucb.

       Solaris provides	some BSD-compatibility functions in
       /usr/ucblib/libucb.a.  Perl will	not build and run correctly if linked
       against -lucb since it contains routines	that are incompatible with the
       standard	Solaris	libc.  Normally	this is	not a problem since the
       solaris hints file prevents Configure from even looking in /usr/ucblib
       for libraries, and also explicitly omits	-lucb.

   Environment for Compiling perl on Solaris
       PATH

       Make sure your PATH includes the	compiler (/opt/SUNWspro/bin/ if	you're
       using Sun's compiler) as	well as	/usr/ccs/bin/ to pick up the other
       development tools (such as make,	ar, as,	and ld).  Make sure your path
       either doesn't include /usr/ucb or that it includes it after the
       compiler	and compiler tools and other standard Solaris directories.
       You definitely don't want /usr/ucb/cc.

       LD_LIBRARY_PATH

       If you have the LD_LIBRARY_PATH environment variable set, be sure that
       it does NOT include /lib	or /usr/lib.  If you will be building
       extensions that call third-party	shared libraries (e.g. Berkeley	DB)
       then make sure that your	LD_LIBRARY_PATH	environment variable includes
       the directory with that library (e.g. /usr/local/lib).

       If you get an error message

	dlopen:	stub interception failed

       it is probably because your LD_LIBRARY_PATH environment variable
       includes	a directory which is a symlink to /usr/lib (such as /lib).
       The reason this causes a	problem	is quite subtle.  The file
       libdl.so.1.0 actually *only* contains functions which generate 'stub
       interception failed' errors!  The runtime linker	intercepts links to
       "/usr/lib/libdl.so.1.0" and links in internal implementations of	those
       functions instead.  [Thanks to Tim Bunce	for this explanation.]

RUN CONFIGURE.
       See the INSTALL file for	general	information regarding Configure.  Only
       Solaris-specific	issues are discussed here.  Usually, the defaults
       should be fine.

   64-bit perl on Solaris.
       See the INSTALL file for	general	information regarding 64-bit compiles.
       In general, the defaults	should be fine for most	people.

       By default, perl-5.6.0 (or later) is compiled as	a 32-bit application
       with largefile and long-long support.

       General 32-bit vs. 64-bit issues.

       Solaris 7 and above will	run in either 32 bit or	64 bit mode on SPARC
       CPUs, via a reboot. You can build 64 bit	apps whilst running 32 bit
       mode and	vice-versa. 32 bit apps	will run under Solaris running in
       either 32 or 64 bit mode.  64 bit apps require Solaris to be running 64
       bit mode.

       Existing	32 bit apps are	properly known as LP32,	i.e. Longs and
       Pointers	are 32 bit.  64-bit apps are more properly known as LP64.  The
       discriminating feature of a LP64	bit app	is its ability to utilise a
       64-bit address space.  It is perfectly possible to have a LP32 bit app
       that supports both 64-bit integers (long	long) and largefiles (>	2GB),
       and this	is the default for perl-5.6.0.

       For a more complete explanation of 64-bit issues, see the "Solaris
       64-bit Developer's Guide" at <http://docs.sun.com/>

       You can detect the OS mode using	"isainfo -v", e.g.

	$ isainfo -v   # Ultra 30 in 64	bit mode
	64-bit sparcv9 applications
	32-bit sparc applications

       By default, perl	will be	compiled as a 32-bit application.  Unless you
       want to allocate	more than ~ 4GB	of memory inside perl, or unless you
       need more than 255 open file descriptors, you probably don't need perl
       to be a 64-bit app.

       Large File Support

       For Solaris 2.6 and onwards, there are two different ways for 32-bit
       applications to manipulate large	files (files whose size	is > 2GByte).
       (A 64-bit application automatically has largefile support built in by
       default.)

       First is	the "transitional compilation environment", described in
       lfcompile64(5).	According to the man page,

	The transitional compilation  environment  exports  all	 the
	explicit 64-bit	functions (xxx64()) and	types in addition to
	all the	regular	functions (xxx()) and types. Both xxx()	 and
	xxx64()	 functions  are	 available to the program source.  A
	32-bit application must	use the	xxx64()	functions in  order
	to  access  large  files.  See the lf64(5) manual page for a
	complete listing of the	64-bit transitional interfaces.

       The transitional	compilation environment	is obtained with the following
       compiler	and linker flags:

	getconf	LFS64_CFLAGS	    -D_LARGEFILE64_SOURCE
	getconf	LFS64_LDFLAG	    # nothing special needed
	getconf	LFS64_LIBS	    # nothing special needed

       Second is the "large file compilation environment", described in
       lfcompile(5).  According	to the man page,

	Each interface named xxx() that	needs to access	64-bit entities
	to  access  large  files maps to a xxx64() call	in the
	resulting binary. All relevant data types are defined to  be
	of correct size	(for example, off_t has	a typedef definition
	for a 64-bit entity).

	An application compiled	in this	environment is able  to	 use
	the  xxx()  source interfaces to access	both large and small
	files, rather than having to explicitly	utilize	the  transitional
	xxx64()	 interface  calls to access large files.

       Two exceptions are fseek() and ftell().	32-bit applications should use
       fseeko(3C) and ftello(3C).  These will get automatically	mapped to
       fseeko64() and ftello64().

       The large file compilation environment is obtained with

	getconf	LFS_CFLAGS	-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64
	getconf	LFS_LDFLAGS	# nothing special needed
	getconf	LFS_LIBS	# nothing special needed

       By default, perl	uses the large file compilation	environment and	relies
       on Solaris to do	the underlying mapping of interfaces.

       Building	an LP64	perl

       To compile a 64-bit application on an UltraSparc	with a recent Sun
       Compiler, you need to use the flag "-xarch=v9".	getconf(1) will	tell
       you this, e.g.

	$ getconf -a | grep v9
	XBS5_LP64_OFF64_CFLAGS:		-xarch=v9
	XBS5_LP64_OFF64_LDFLAGS:	-xarch=v9
	XBS5_LP64_OFF64_LINTFLAGS:	-xarch=v9
	XBS5_LPBIG_OFFBIG_CFLAGS:	-xarch=v9
	XBS5_LPBIG_OFFBIG_LDFLAGS:	-xarch=v9
	XBS5_LPBIG_OFFBIG_LINTFLAGS:	-xarch=v9
	_XBS5_LP64_OFF64_CFLAGS:	-xarch=v9
	_XBS5_LP64_OFF64_LDFLAGS:	-xarch=v9
	_XBS5_LP64_OFF64_LINTFLAGS:	-xarch=v9
	_XBS5_LPBIG_OFFBIG_CFLAGS:	-xarch=v9
	_XBS5_LPBIG_OFFBIG_LDFLAGS:	-xarch=v9
	_XBS5_LPBIG_OFFBIG_LINTFLAGS:	-xarch=v9

       This flag is supported in Sun WorkShop Compilers	5.0 and	onwards	(now
       marketed	under the name Forte) when used	on Solaris 7 or	later on
       UltraSparc systems.

       If you are using	gcc, you would need to use -mcpu=v9 -m64 instead.
       This option is not yet supported	as of gcc 2.95.2; from
       install/SPECIFIC	in that	release:

	GCC version 2.95 is not	able to	compile	code correctly for sparc64
	targets. Users of the Linux kernel, at least, can use the sparc32
	program	to start up a new shell	invocation with	an environment that
	causes configure to recognize (via uname -a) the system	as sparc-*-*
	instead.

       All this	should be handled automatically	by the hints file, if
       requested.

       Long Doubles.

       As of 5.8.1, long doubles are working if	you use	the Sun	compilers
       (needed for additional math routines not	included in libm).

   Threads in perl on Solaris.
       It is possible to build a threaded version of perl on Solaris.  The
       entire perl thread implementation is still experimental,	however, so
       beware.

   Malloc Issues with perl on Solaris.
       Starting	from perl 5.7.1	perl uses the Solaris malloc, since the	perl
       malloc breaks when dealing with more than 2GB of	memory,	and the
       Solaris malloc also seems to be faster.

       If you for some reason (such as binary backward compatibility) really
       need to use perl's malloc, you can rebuild perl from the	sources	and
       Configure the build with

	$ sh Configure -Dusemymalloc

       You should not use perl's malloc	if you are building with gcc.  There
       are reports of core dumps, especially in	the PDL	module.	 The problem
       appears to go away under	-DDEBUGGING, so	it has been difficult to track
       down.  Sun's compiler appears to	be okay	with or	without	perl's malloc.
       [XXX further investigation is needed here.]

MAKE PROBLEMS.
       Dynamic Loading Problems	With GNU as and	GNU ld
	   If you have problems	with dynamic loading using gcc on SunOS	or
	   Solaris, and	you are	using GNU as and GNU ld, see the section "GNU
	   as and GNU ld" above.

       ld.so.1:	./perl:	fatal: relocation error:
	   If you get this message on SunOS or Solaris,	and you're using gcc,
	   it's	probably the GNU as or GNU ld problem in the previous item
	   "GNU	as and GNU ld".

       dlopen: stub interception failed
	   The primary cause of	the 'dlopen: stub interception failed' message
	   is that the LD_LIBRARY_PATH environment variable includes a
	   directory which is a	symlink	to /usr/lib (such as /lib).  See
	   "LD_LIBRARY_PATH" above.

       #error "No DATAMODEL_NATIVE specified"
	   This	is a common error when trying to build perl on Solaris 2.6
	   with	a gcc installation from	Solaris	2.5 or 2.5.1.  The Solaris
	   header files	changed, so you	need to	update your gcc	installation.
	   You can either rerun	the fixincludes	script from gcc	or take	the
	   opportunity to update your gcc installation.

       sh: ar: not found
	   This	is a message from your shell telling you that the command 'ar'
	   was not found.  You need to check your PATH environment variable to
	   make	sure that it includes the directory with the 'ar' command.
	   This	is a common problem on Solaris,	where 'ar' is in the
	   /usr/ccs/bin/ directory.

MAKE TEST
   op/stat.t test 4 in Solaris
       op/stat.t test 4	may fail if you	are on a tmpfs of some sort.  Building
       in /tmp sometimes shows this behavior.  The test	suite detects if you
       are building in /tmp, but it may	not be able to catch all tmpfs
       situations.

   nss_delete core dump	from op/pwent or op/grent
       See "nss_delete core dump from op/pwent or op/grent" in perlhpux.

CROSS-COMPILATION
       Nothing too unusual here.  You can easily do this if you	have a cross-
       compiler	available;  A usual Configure invocation when targetting a
       Solaris x86 looks something like	this:

	   sh ./Configure -des -Dusecrosscompile \
	       -Dcc=i386-pc-solaris2.11-gcc	 \
	       -Dsysroot=$SYSROOT		 \
	       -Alddlflags=" -Wl,-z,notext"	 \
	       -Dtargethost=...	# The usual cross-compilation options

       The lddlflags addition is the only abnormal bit.

PREBUILT BINARIES OF PERL FOR SOLARIS.
       You can pick up prebuilt	binaries for Solaris from
       <http://www.sunfreeware.com/>, <http://www.blastwave.org>, ActiveState
       <http://www.activestate.com/>, and <http://www.perl.com/> under the
       Binaries	list at	the top	of the page.  There are	probably other sources
       as well.	 Please	note that these	sites are under	the control of their
       respective owners, not the perl developers.

RUNTIME	ISSUES FOR PERL	ON SOLARIS.
   Limits on Numbers of	Open Files on Solaris.
       The stdio(3C) manpage notes that	for LP32 applications, only 255	files
       may be opened using fopen(), and	only file descriptors 0	through	255
       can be used in a	stream.	 Since perl calls open() and then fdopen(3C)
       with the	resulting file descriptor, perl	is limited to 255 simultaneous
       open files, even	if sysopen() is	used.  If this proves to be an
       insurmountable problem, you can compile perl as a LP64 application, see
       "Building an LP64 perl" for details.  Note also that the	default
       resource	limit for open file descriptors	on Solaris is 255, so you will
       have to modify your ulimit or rctl (Solaris 9 onwards) appropriately.

SOLARIS-SPECIFIC MODULES.
       See the modules under the Solaris:: and Sun::Solaris namespaces on
       CPAN, see <http://www.cpan.org/modules/by-module/Solaris/> and
       <http://www.cpan.org/modules/by-module/Sun/>.

SOLARIS-SPECIFIC PROBLEMS WITH MODULES.
   Proc::ProcessTable on Solaris
       Proc::ProcessTable does not compile on Solaris with perl5.6.0 and
       higher if you have LARGEFILES defined.  Since largefile support is the
       default in 5.6.0	and later, you have to take special steps to use this
       module.

       The problem is that various structures visible via procfs use off_t,
       and if you compile with largefile support these change from 32 bits to
       64 bits.	 Thus what you get back	from procfs doesn't match up with the
       structures in perl, resulting in	garbage.  See proc(4) for further
       discussion.

       A fix for Proc::ProcessTable is to edit Makefile	to explicitly remove
       the largefile flags from	the ones MakeMaker picks up from Config.pm.
       This will result	in Proc::ProcessTable being built under	the correct
       environment.  Everything	should then be OK as long as
       Proc::ProcessTable doesn't try to share off_t's with the	rest of	perl,
       or if it	does they should be explicitly specified as off64_t.

   BSD::Resource on Solaris
       BSD::Resource versions earlier than 1.09	do not compile on Solaris with
       perl 5.6.0 and higher, for the same reasons as Proc::ProcessTable.
       BSD::Resource versions starting from 1.09 have a	workaround for the
       problem.

   Net::SSLeay on Solaris
       Net::SSLeay requires a /dev/urandom to be present. This device is
       available from Solaris 9	onwards.  For earlier Solaris versions you can
       either get the package SUNWski (packaged	with several Sun software
       products, for example the Sun WebServer,	which is part of the Solaris
       Server Intranet Extension, or the Sun Directory Services, part of
       Solaris for ISPs) or download the ANDIrand package from
       <http://www.cosy.sbg.ac.at/~andi/>. If you use SUNWski, make a symbolic
       link /dev/urandom pointing to /dev/random.  For more details, see
       Document	ID27606	entitled "Differing /dev/random	support	requirements
       within Solaris[TM] Operating Environments", available at
       <http://sunsolve.sun.com> .

       It may be possible to use the Entropy Gathering Daemon (written in
       Perl!), available from <http://www.lothar.com/tech/crypto/>.

SunOS 4.x
       In SunOS	4.x you	most probably want to use the SunOS ld,	/usr/bin/ld,
       since the more recent versions of GNU ld	(like 2.13) do not seem	to
       work for	building Perl anymore.	When linking the extensions, the GNU
       ld gets very unhappy and	spews a	lot of errors like this

	 ... relocation	truncated to fit: BASE13 ...

       and dies.  Therefore the	SunOS 4.1 hints	file explicitly	sets the ld to
       be /usr/bin/ld.

       As of Perl 5.8.1	the dynamic loading of libraries (DynaLoader,
       XSLoader) also seems to have become broken in in	SunOS 4.x.  Therefore
       the default is to build Perl statically.

       Running the test	suite in SunOS 4.1 is a	bit tricky since the
       dist/Tie-File/t/09_gen_rs.t test	hangs (subtest #51, FWIW) for some
       unknown reason.	Just stop the test and kill that particular Perl
       process.

       There are various other failures, that as of SunOS 4.1.4	and gcc	3.2.2
       look a lot like gcc bugs.  Many of the failures happen in the Encode
       tests, where for	example	when the test expects "0" you get "&#48;"
       which should after a little squinting look very odd indeed.  Another
       example is earlier in t/run/fresh_perl where chr(0xff) is expected but
       the test	fails because the result is chr(0xff).	Exactly.

       This is the "make test" result from the said combination:

	 Failed	27 test	scripts	out of 745, 96.38% okay.

       Running the "harness" is	painful	because	of the many failing Unicode-
       related tests will output megabytes of failure messages,	but if one
       patiently waits,	one gets these results:

       The alarm() test	failure	is caused by system() apparently blocking
       alarm().	 That is probably a libc bug, and given	that SunOS 4.x has
       been end-of-lifed years ago, don't hold your breath for a fix.  In
       addition	to that, don't try anything too	Unicode-y, especially with
       Encode, and you should be fine in SunOS 4.x.
