NAME

6       README.solaris - Perl version 5 on Solaris systems

DESCRIPTION

9       This document describes various features of Sun's Solaris operating
10       system that will affect how Perl version 5 (hereafter just perl) is
11       compiled and/or runs.  Some issues relating to the older SunOS 4.x are
12       also discussed, though they may be out of date.
13
14       For the most part, everything should just work.
15
16       Starting with Solaris 8, perl5.00503 (or higher) is supplied with the
17       operating system, so you might not even need to build a newer version
18       of perl at all.  The Sun-supplied version is installed in /usr/perl5
19       with /usr/bin/perl pointing to /usr/perl5/bin/perl.  Do not disturb
20       that installation unless you really know what you are doing.  If you
21       remove the perl supplied with the OS, you will render some bits of your
22       system inoperable.  If you wish to install a newer version of perl,
23       install it under a different prefix from /usr/perl5.  Common prefixes
24       to use are /usr/local and /opt/perl.
25
26       You may wish to put your version of perl in the PATH of all users by
27       changing the link /usr/bin/perl.  This is probably OK, as most perl
28       scripts shipped with Solaris use an explicit path.  (There are a few
29       exceptions, such as /usr/bin/rpm2cpio and /etc/rcm/scripts/README, but
30       these are also sufficiently generic that the actual version of perl
31       probably doesn't matter too much.)
32
33       Solaris ships with a range of Solaris-specific modules.  If you choose
34       to install your own version of perl you will find the source of many of
35       these modules is available on CPAN under the Sun::Solaris:: namespace.
36
37       Solaris may include two versions of perl, e.g. Solaris 9 includes both
38       5.005_03 and 5.6.1.  This is to provide stability across Solaris
39       releases, in cases where a later perl version has incompatibilities
40       with the version included in the preceeding Solaris release.  The
41       default perl version will always be the most recent, and in general the
42       old version will only be retained for one Solaris release.  Note also
43       that the default perl will NOT be configured to search for modules in
44       the older version, again due to compatibility/stability concerns.  As a
45       consequence if you upgrade Solaris, you will have to rebuild/reinstall
46       any additional CPAN modules that you installed for the previous Solaris
47       version.  See the CPAN manpage under 'autobundle' for a quick way of
48       doing this.
49
50       As an interim measure, you may either change the #! line of your
51       scripts to specifically refer to the old perl version, e.g. on Solaris
52       9 use #!/usr/perl5/5.00503/bin/perl to use the perl version that was
53       the default for Solaris 8, or if you have a large number of scripts it
54       may be more convenient to make the old version of perl the default on
55       your system.  You can do this by changing the appropriate symlinks
56       under /usr/perl5 as follows (example for Solaris 9):
57
58        # cd /usr/perl5
59        # rm bin man pod
60        # ln -s ./5.00503/bin
61        # ln -s ./5.00503/man
62        # ln -s ./5.00503/lib/pod
63        # rm /usr/bin/perl
64        # ln -s ../perl5/5.00503/bin/perl /usr/bin/perl
65
66       In both cases this should only be considered to be a temporary measure
67       - you should upgrade to the later version of perl as soon as is
68       practicable.
69
70       Note also that the perl command-line utilities (e.g. perldoc) and any
71       that are added by modules that you install will be under
72       /usr/perl5/bin, so that directory should be added to your PATH.
73
74   Solaris Version Numbers.
75       For consistency with common usage, perl's Configure script performs
76       some minor manipulations on the operating system name and version
77       number as reported by uname.  Here's a partial translation table:
78
79                 Sun:                      perl's Configure:
80        uname    uname -r   Name           osname     osvers
81        SunOS    4.1.3     Solaris 1.1     sunos      4.1.3
82        SunOS    5.6       Solaris 2.6     solaris    2.6
83        SunOS    5.8       Solaris 8       solaris    2.8
84        SunOS    5.9       Solaris 9       solaris    2.9
85        SunOS    5.10      Solaris 10      solaris    2.10
86
87       The complete table can be found in the Sun Managers' FAQ

89       Sun models run which versions of SunOS?".

SETTING UP

112   File Extraction Problems on Solaris.
113       Be sure to use a tar program compiled under Solaris (not SunOS 4.x) to
114       extract the perl-5.x.x.tar.gz file.  Do not use GNU tar compiled for
115       SunOS4 on Solaris.  (GNU tar compiled for Solaris should be fine.)
116       When you run SunOS4 binaries on Solaris, the run-time system magically
117       alters pathnames matching m#lib/locale# so that when tar tries to
118       create lib/locale.pm, a file named lib/oldlocale.pm gets created
119       instead.  If you found this advice too late and used a SunOS4-compiled
120       tar anyway, you must find the incorrectly renamed file and move it back
121       to lib/locale.pm.
122
123   Compiler and Related Tools on Solaris.
124       You must use an ANSI C compiler to build perl.  Perl can be compiled
125       with either Sun's add-on C compiler or with gcc.  The C compiler that
126       shipped with SunOS4 will not do.
127
128       Include /usr/ccs/bin/ in your PATH.
129
130       Several tools needed to build perl are located in /usr/ccs/bin/:  ar,
131       as, ld, and make.  Make sure that /usr/ccs/bin/ is in your PATH.
132
133       You need to make sure the following packages are installed (this info
134       is extracted from the Solaris FAQ):
135
136       for tools (sccs, lex, yacc, make, nm, truss, ld, as): SUNWbtool,
137       SUNWsprot, SUNWtoo
138
139       for libraries & headers: SUNWhea, SUNWarc, SUNWlibm, SUNWlibms,
140       SUNWdfbh, SUNWcg6h, SUNWxwinc, SUNWolinc
141
142       for 64 bit development: SUNWarcx, SUNWbtoox, SUNWdplx, SUNWscpux,
143       SUNWsprox, SUNWtoox, SUNWlmsx, SUNWlmx, SUNWlibCx
144
145       If you are in doubt which package contains a file you are missing, try
146       to find an installation that has that file. Then do a
147
148        $ grep /my/missing/file /var/sadm/install/contents
149
150       This will display a line like this:
151
152       /usr/include/sys/errno.h f none 0644 root bin 7471 37605 956241356
153       SUNWhea
154
155       The last item listed (SUNWhea in this example) is the package you need.
156
157       Avoid /usr/ucb/cc.
158
159       You don't need to have /usr/ucb/ in your PATH to build perl.  If you
160       want /usr/ucb/ in your PATH anyway, make sure that /usr/ucb/ is NOT in
161       your PATH before the directory containing the right C compiler.
162
163       Sun's C Compiler
164
165       If you use Sun's C compiler, make sure the correct directory (usually
166       /opt/SUNWspro/bin/) is in your PATH (before /usr/ucb/).
167
168       GCC
169
170       If you use gcc, make sure your installation is recent and complete.
171       perl versions since 5.6.0 build fine with gcc > 2.8.1 on Solaris >=
172       2.6.
173
174       You must Configure perl with
175
176        $ sh Configure -Dcc=gcc
177
178       If you don't, you may experience strange build errors.
179
180       If you have updated your Solaris version, you may also have to update
181       your gcc.  For example, if you are running Solaris 2.6 and your gcc is
182       installed under /usr/local, check in /usr/local/lib/gcc-lib and make
183       sure you have the appropriate directory, sparc-sun-solaris2.6/ or
184       i386-pc-solaris2.6/.  If gcc's directory is for a different version of
185       Solaris than you are running, then you will need to rebuild gcc for
186       your new version of Solaris.
187
188       You can get a precompiled version of gcc from
189       <http://www.sunfreeware.com/> or <http://www.blastwave.org/>. Make sure
190       you pick up the package for your Solaris release.
191
192       If you wish to use gcc to build add-on modules for use with the perl
193       shipped with Solaris, you should use the Solaris::PerlGcc module which
194       is available from CPAN.  The perl shipped with Solaris is configured
195       and built with the Sun compilers, and the compiler configuration
196       information stored in Config.pm is therefore only relevant to the Sun
197       compilers.  The Solaris:PerlGcc module contains a replacement Config.pm
198       that is correct for gcc - see the module for details.
199
200       GNU as and GNU ld
201
202       The following information applies to gcc version 2.  Volunteers to
203       update it as appropropriate for gcc version 3 would be appreciated.
204
205       The versions of as and ld supplied with Solaris work fine for building
206       perl.  There is normally no need to install the GNU versions to compile
207       perl.
208
209       If you decide to ignore this advice and use the GNU versions anyway,
210       then be sure that they are relatively recent.  Versions newer than 2.7
211       are apparently new enough.  Older versions may have trouble with
212       dynamic loading.
213
214       If you wish to use GNU ld, then you need to pass it the -Wl,-E flag.
215       The hints/solaris_2.sh file tries to do this automatically by setting
216       the following Configure variables:
217
218        ccdlflags="$ccdlflags -Wl,-E"
219        lddlflags="$lddlflags -Wl,-E -G"
220
221       However, over the years, changes in gcc, GNU ld, and Solaris ld have
222       made it difficult to automatically detect which ld ultimately gets
223       called.  You may have to manually edit config.sh and add the -Wl,-E
224       flags yourself, or else run Configure interactively and add the flags
225       at the appropriate prompts.
226
227       If your gcc is configured to use GNU as and ld but you want to use the
228       Solaris ones instead to build perl, then you'll need to add
229       -B/usr/ccs/bin/ to the gcc command line.  One convenient way to do that
230       is with
231
232        $ sh Configure -Dcc='gcc -B/usr/ccs/bin/'
233
234       Note that the trailing slash is required.  This will result in some
235       harmless warnings as Configure is run:
236
237        gcc: file path prefix `/usr/ccs/bin/' never used
238
239       These messages may safely be ignored.  (Note that for a SunOS4 system,
240       you must use -B/bin/ instead.)
241
242       Alternatively, you can use the GCC_EXEC_PREFIX environment variable to
243       ensure that Sun's as and ld are used.  Consult your gcc documentation
244       for further information on the -B option and the GCC_EXEC_PREFIX
245       variable.
246
247       Sun and GNU make
248
249       The make under /usr/ccs/bin works fine for building perl.  If you have
250       the Sun C compilers, you will also have a parallel version of make
251       (dmake).  This works fine to build perl, but can sometimes cause
252       problems when running 'make test' due to underspecified dependencies
253       between the different test harness files.  The same problem can also
254       affect the building of some add-on modules, so in those cases either
255       specify '-m serial' on the dmake command line, or use /usr/ccs/bin/make
256       instead.  If you wish to use GNU make, be sure that the set-group-id
257       bit is not set.  If it is, then arrange your PATH so that
258       /usr/ccs/bin/make is before GNU make or else have the system
259       administrator disable the set-group-id bit on GNU make.
260
261       Avoid libucb.
262
263       Solaris provides some BSD-compatibility functions in
264       /usr/ucblib/libucb.a.  Perl will not build and run correctly if linked
265       against -lucb since it contains routines that are incompatible with the
266       standard Solaris libc.  Normally this is not a problem since the
267       solaris hints file prevents Configure from even looking in /usr/ucblib
268       for libraries, and also explicitly omits -lucb.
269
270   Environment for Compiling perl on Solaris
271       PATH
272
273       Make sure your PATH includes the compiler (/opt/SUNWspro/bin/ if you're
274       using Sun's compiler) as well as /usr/ccs/bin/ to pick up the other
275       development tools (such as make, ar, as, and ld).  Make sure your path
276       either doesn't include /usr/ucb or that it includes it after the
277       compiler and compiler tools and other standard Solaris directories.
278       You definitely don't want /usr/ucb/cc.
279
280       LD_LIBRARY_PATH
281
282       If you have the LD_LIBRARY_PATH environment variable set, be sure that
283       it does NOT include /lib or /usr/lib.  If you will be building
284       extensions that call third-party shared libraries (e.g. Berkeley DB)
285       then make sure that your LD_LIBRARY_PATH environment variable includes
286       the directory with that library (e.g. /usr/local/lib).
287
288       If you get an error message
289
290        dlopen: stub interception failed
291
292       it is probably because your LD_LIBRARY_PATH environment variable
293       includes a directory which is a symlink to /usr/lib (such as /lib).
294       The reason this causes a problem is quite subtle.  The file
295       libdl.so.1.0 actually *only* contains functions which generate 'stub
296       interception failed' errors!  The runtime linker intercepts links to
297       "/usr/lib/libdl.so.1.0" and links in internal implementations of those
298       functions instead.  [Thanks to Tim Bunce for this explanation.]

RUN CONFIGURE.

301       See the INSTALL file for general information regarding Configure.  Only
302       Solaris-specific issues are discussed here.  Usually, the defaults
303       should be fine.
304
305   64-bit perl on Solaris.
306       See the INSTALL file for general information regarding 64-bit compiles.
307       In general, the defaults should be fine for most people.
308
309       By default, perl-5.6.0 (or later) is compiled as a 32-bit application
310       with largefile and long-long support.
311
312       General 32-bit vs. 64-bit issues.
313
314       Solaris 7 and above will run in either 32 bit or 64 bit mode on SPARC
315       CPUs, via a reboot. You can build 64 bit apps whilst running 32 bit
316       mode and vice-versa. 32 bit apps will run under Solaris running in
317       either 32 or 64 bit mode.  64 bit apps require Solaris to be running 64
318       bit mode.
319
320       Existing 32 bit apps are properly known as LP32, i.e. Longs and
321       Pointers are 32 bit.  64-bit apps are more properly known as LP64.  The
322       discriminating feature of a LP64 bit app is its ability to utilise a
323       64-bit address space.  It is perfectly possible to have a LP32 bit app
324       that supports both 64-bit integers (long long) and largefiles (> 2GB),
325       and this is the default for perl-5.6.0.
326
327       For a more complete explanation of 64-bit issues, see the "Solaris
328       64-bit Developer's Guide" at <http://docs.sun.com/>
329
330       You can detect the OS mode using "isainfo -v", e.g.
331
332        $ isainfo -v   # Ultra 30 in 64 bit mode
333        64-bit sparcv9 applications
334        32-bit sparc applications
335
336       By default, perl will be compiled as a 32-bit application.  Unless you
337       want to allocate more than ~ 4GB of memory inside perl, or unless you
338       need more than 255 open file descriptors, you probably don't need perl
339       to be a 64-bit app.
340
341       Large File Support
342
343       For Solaris 2.6 and onwards, there are two different ways for 32-bit
344       applications to manipulate large files (files whose size is > 2GByte).
345       (A 64-bit application automatically has largefile support built in by
346       default.)
347
348       First is the "transitional compilation environment", described in
349       lfcompile64(5).  According to the man page,
350
351        The transitional compilation  environment  exports  all  the
352        explicit 64-bit functions (xxx64()) and types in addition to
353        all the regular functions (xxx()) and types. Both xxx()  and
354        xxx64()  functions  are  available to the program source.  A
355        32-bit application must use the xxx64() functions in  order
356        to  access  large  files.  See the lf64(5) manual page for a
357        complete listing of the 64-bit transitional interfaces.
358
359       The transitional compilation environment is obtained with the following
360       compiler and linker flags:
361
362        getconf LFS64_CFLAGS        -D_LARGEFILE64_SOURCE
363        getconf LFS64_LDFLAG        # nothing special needed
364        getconf LFS64_LIBS          # nothing special needed
365
366       Second is the "large file compilation environment", described in
367       lfcompile(5).  According to the man page,
368
369        Each interface named xxx() that needs to access 64-bit entities
370        to  access  large  files maps to a xxx64() call in the
371        resulting binary. All relevant data types are defined to  be
372        of correct size (for example, off_t has a typedef definition
373        for a 64-bit entity).
374
375        An application compiled in this environment is able  to  use
376        the  xxx()  source interfaces to access both large and small
377        files, rather than having to explicitly utilize the  transitional
378        xxx64()  interface  calls to access large files.
379
380       Two exceptions are fseek() and ftell().  32-bit applications should use
381       fseeko(3C) and ftello(3C).  These will get automatically mapped to
382       fseeko64() and ftello64().
383
384       The large file compilation environment is obtained with
385
386        getconf LFS_CFLAGS      -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64
387        getconf LFS_LDFLAGS     # nothing special needed
388        getconf LFS_LIBS        # nothing special needed
389
390       By default, perl uses the large file compilation environment and relies
391       on Solaris to do the underlying mapping of interfaces.
392
393       Building an LP64 perl
394
395       To compile a 64-bit application on an UltraSparc with a recent Sun
396       Compiler, you need to use the flag "-xarch=v9".  getconf(1) will tell
397       you this, e.g.
398
399        $ getconf -a | grep v9
400        XBS5_LP64_OFF64_CFLAGS:         -xarch=v9
401        XBS5_LP64_OFF64_LDFLAGS:        -xarch=v9
402        XBS5_LP64_OFF64_LINTFLAGS:      -xarch=v9
403        XBS5_LPBIG_OFFBIG_CFLAGS:       -xarch=v9
404        XBS5_LPBIG_OFFBIG_LDFLAGS:      -xarch=v9
405        XBS5_LPBIG_OFFBIG_LINTFLAGS:    -xarch=v9
406        _XBS5_LP64_OFF64_CFLAGS:        -xarch=v9
407        _XBS5_LP64_OFF64_LDFLAGS:       -xarch=v9
408        _XBS5_LP64_OFF64_LINTFLAGS:     -xarch=v9
409        _XBS5_LPBIG_OFFBIG_CFLAGS:      -xarch=v9
410        _XBS5_LPBIG_OFFBIG_LDFLAGS:     -xarch=v9
411        _XBS5_LPBIG_OFFBIG_LINTFLAGS:   -xarch=v9
412
413       This flag is supported in Sun WorkShop Compilers 5.0 and onwards (now
414       marketed under the name Forte) when used on Solaris 7 or later on
415       UltraSparc systems.
416
417       If you are using gcc, you would need to use -mcpu=v9 -m64 instead.
418       This option is not yet supported as of gcc 2.95.2; from
419       install/SPECIFIC in that release:
420
421        GCC version 2.95 is not able to compile code correctly for sparc64
422        targets. Users of the Linux kernel, at least, can use the sparc32
423        program to start up a new shell invocation with an environment that
424        causes configure to recognize (via uname -a) the system as sparc-*-*
425        instead.
426
427       All this should be handled automatically by the hints file, if
428       requested.
429
430       Long Doubles.
431
432       As of 5.8.1, long doubles are working if you use the Sun compilers
433       (needed for additional math routines not included in libm).
434
435   Threads in perl on Solaris.
436       It is possible to build a threaded version of perl on Solaris.  The
437       entire perl thread implementation is still experimental, however, so
438       beware.
439
440   Malloc Issues with perl on Solaris.
441       Starting from perl 5.7.1 perl uses the Solaris malloc, since the perl
442       malloc breaks when dealing with more than 2GB of memory, and the
443       Solaris malloc also seems to be faster.
444
445       If you for some reason (such as binary backward compatibility) really
446       need to use perl's malloc, you can rebuild perl from the sources and
447       Configure the build with
448
449        $ sh Configure -Dusemymalloc
450
451       You should not use perl's malloc if you are building with gcc.  There
452       are reports of core dumps, especially in the PDL module.  The problem
453       appears to go away under -DDEBUGGING, so it has been difficult to track
454       down.  Sun's compiler appears to be okay with or without perl's malloc.
455       [XXX further investigation is needed here.]

MAKE PROBLEMS.

458       Dynamic Loading Problems With GNU as and GNU ld
459           If you have problems with dynamic loading using gcc on SunOS or
460           Solaris, and you are using GNU as and GNU ld, see the section "GNU
461           as and GNU ld" above.
462
463       ld.so.1: ./perl: fatal: relocation error:
464           If you get this message on SunOS or Solaris, and you're using gcc,
465           it's probably the GNU as or GNU ld problem in the previous item
466           "GNU as and GNU ld".
467
468       dlopen: stub interception failed
469           The primary cause of the 'dlopen: stub interception failed' message
470           is that the LD_LIBRARY_PATH environment variable includes a
471           directory which is a symlink to /usr/lib (such as /lib).  See
472           "LD_LIBRARY_PATH" above.
473
474       #error "No DATAMODEL_NATIVE specified"
475           This is a common error when trying to build perl on Solaris 2.6
476           with a gcc installation from Solaris 2.5 or 2.5.1.  The Solaris
477           header files changed, so you need to update your gcc installation.
478           You can either rerun the fixincludes script from gcc or take the
479           opportunity to update your gcc installation.
480
481       sh: ar: not found
482           This is a message from your shell telling you that the command 'ar'
483           was not found.  You need to check your PATH environment variable to
484           make sure that it includes the directory with the 'ar' command.
485           This is a common problem on Solaris, where 'ar' is in the
486           /usr/ccs/bin/ directory.
487

MAKE TEST

489   op/stat.t test 4 in Solaris
490       op/stat.t test 4 may fail if you are on a tmpfs of some sort.  Building
491       in /tmp sometimes shows this behavior.  The test suite detects if you
492       are building in /tmp, but it may not be able to catch all tmpfs
493       situations.
494
495   nss_delete core dump from op/pwent or op/grent
496       See "nss_delete core dump from op/pwent or op/grent" in perlhpux.
497

PREBUILT BINARIES OF PERL FOR SOLARIS.

499       You can pick up prebuilt binaries for Solaris from
500       <http://www.sunfreeware.com/>, <http://www.blastwave.org>, ActiveState
501       <http://www.activestate.com/>, and <http://www.perl.com/> under the
502       Binaries list at the top of the page.  There are probably other sources
503       as well.  Please note that these sites are under the control of their
504       respective owners, not the perl developers.
505

RUNTIME ISSUES FOR PERL ON SOLARIS.

507   Limits on Numbers of Open Files on Solaris.
508       The stdio(3C) manpage notes that for LP32 applications, only 255 files
509       may be opened using fopen(), and only file descriptors 0 through 255
510       can be used in a stream.  Since perl calls open() and then fdopen(3C)
511       with the resulting file descriptor, perl is limited to 255 simultaneous
512       open files, even if sysopen() is used.  If this proves to be an
513       insurmountable problem, you can compile perl as a LP64 application, see
514       "Building an LP64 perl" for details.  Note also that the default
515       resource limit for open file descriptors on Solaris is 255, so you will
516       have to modify your ulimit or rctl (Solaris 9 onwards) appropriately.
517

SOLARIS-SPECIFIC MODULES.

519       See the modules under the Solaris:: and Sun::Solaris namespaces on
520       CPAN, see <http://www.cpan.org/modules/by-module/Solaris/> and
521       <http://www.cpan.org/modules/by-module/Sun/>.
522

SOLARIS-SPECIFIC PROBLEMS WITH MODULES.

524   Proc::ProcessTable on Solaris
525       Proc::ProcessTable does not compile on Solaris with perl5.6.0 and
526       higher if you have LARGEFILES defined.  Since largefile support is the
527       default in 5.6.0 and later, you have to take special steps to use this
528       module.
529
530       The problem is that various structures visible via procfs use off_t,
531       and if you compile with largefile support these change from 32 bits to
532       64 bits.  Thus what you get back from procfs doesn't match up with the
533       structures in perl, resulting in garbage.  See proc(4) for further
534       discussion.
535
536       A fix for Proc::ProcessTable is to edit Makefile to explicitly remove
537       the largefile flags from the ones MakeMaker picks up from Config.pm.
538       This will result in Proc::ProcessTable being built under the correct
539       environment.  Everything should then be OK as long as
540       Proc::ProcessTable doesn't try to share off_t's with the rest of perl,
541       or if it does they should be explicitly specified as off64_t.
542
543   BSD::Resource on Solaris
544       BSD::Resource versions earlier than 1.09 do not compile on Solaris with
545       perl 5.6.0 and higher, for the same reasons as Proc::ProcessTable.
546       BSD::Resource versions starting from 1.09 have a workaround for the
547       problem.
548
549   Net::SSLeay on Solaris
550       Net::SSLeay requires a /dev/urandom to be present. This device is
551       available from Solaris 9 onwards.  For earlier Solaris versions you can
552       either get the package SUNWski (packaged with several Sun software
553       products, for example the Sun WebServer, which is part of the Solaris
554       Server Intranet Extension, or the Sun Directory Services, part of
555       Solaris for ISPs) or download the ANDIrand package from
556       <http://www.cosy.sbg.ac.at/~andi/>. If you use SUNWski, make a symbolic
557       link /dev/urandom pointing to /dev/random.  For more details, see
558       Document ID27606 entitled "Differing /dev/random support requirements
559       within Solaris[TM] Operating Environments", available at
560       http://sunsolve.sun.com .
561
562       It may be possible to use the Entropy Gathering Daemon (written in
563       Perl!), available from <http://www.lothar.com/tech/crypto/>.
564

SunOS 4.x

566       In SunOS 4.x you most probably want to use the SunOS ld, /usr/bin/ld,
567       since the more recent versions of GNU ld (like 2.13) do not seem to
568       work for building Perl anymore.  When linking the extensions, the GNU
569       ld gets very unhappy and spews a lot of errors like this
570
571         ... relocation truncated to fit: BASE13 ...
572
573       and dies.  Therefore the SunOS 4.1 hints file explicitly sets the ld to
574       be /usr/bin/ld.
575
576       As of Perl 5.8.1 the dynamic loading of libraries (DynaLoader,
577       XSLoader) also seems to have become broken in in SunOS 4.x.  Therefore
578       the default is to build Perl statically.
579
580       Running the test suite in SunOS 4.1 is a bit tricky since the
581       lib/Tie/File/t/09_gen_rs test hangs (subtest #51, FWIW) for some
582       unknown reason.  Just stop the test and kill that particular Perl
583       process.
584
585       There are various other failures, that as of SunOS 4.1.4 and gcc 3.2.2
586       look a lot like gcc bugs.  Many of the failures happen in the Encode
587       tests, where for example when the test expects "0" you get "&#48;"
588       which should after a little squinting look very odd indeed.  Another
589       example is earlier in t/run/fresh_perl where chr(0xff) is expected but
590       the test fails because the result is chr(0xff).  Exactly.
591
592       This is the "make test" result from the said combination:
593
594         Failed 27 test scripts out of 745, 96.38% okay.
595
596       Running the "harness" is painful because of the many failing Unicode-
597       related tests will output megabytes of failure messages, but if one
598       patiently waits, one gets these results:

639
640       The alarm() test failure is caused by system() apparently blocking
641       alarm().  That is probably a libc bug, and given that SunOS 4.x has
642       been end-of-lifed years ago, don't hold your breath for a fix.  In
643       addition to that, don't try anything too Unicode-y, especially with
644       Encode, and you should be fine in SunOS 4.x.
