- =head1 NAME
-
- README.solaris - Perl version 5 on Solaris systems
-
- =head1 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- also discussed, though they may be out of date.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 OK, as all perl scripts
- shipped with Solaris use an explicit path. 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 preceeding 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.
-
- =head2 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
- L<ftp://ftp.cs.toronto.edu/pub/jdd/sunmanagers/faq> under
- "9.1) Which Sun models run which versions of SunOS?".
-
- =head1 RESOURCES
-
- There are many, many sources for Solaris information. A few of the
- important ones for perl:
-
- =over 4
-
- =item Solaris FAQ
-
- The Solaris FAQ is available at
- L<http://www.science.uva.nl/pub/solaris/solaris2.html>.
-
- The Sun Managers' FAQ is available at
- L<ftp://ftp.cs.toronto.edu/pub/jdd/sunmanagers/faq>
-
- =item Precompiled Binaries
-
- Precompiled binaries, links to many sites, and much, much more are
- available at L<http://www.sunfreeware.com/> and
- L<http://www.blastwave.org/>.
-
- =item Solaris Documentation
-
- All Solaris documentation is available on-line at L<http://docs.sun.com/>.
-
- =back
-
- =head1 SETTING UP
-
- =head2 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.
-
- =head2 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.
-
- =head3 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.
-
- 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, SUNWolinc
-
- for 64 bit development: SUNWarcx, SUNWbtoox, SUNWdplx, SUNWscpux,
- SUNWsprox, SUNWtoox, SUNWlmsx, SUNWlmx, SUNWlibCx
-
- 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.
-
- =head3 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.
-
- =head3 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/).
-
- =head3 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
- L<http://www.sunfreeware.com/> or L<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.
-
- =head3 GNU as and GNU ld
-
- The following information applies to gcc version 2. Volunteers to
- update it as appropropriate 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.
-
- =head3 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.
-
- =head3 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.
-
- =head2 Environment for Compiling perl on Solaris
-
- =head3 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.
-
- =head3 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.]
-
- =head1 RUN CONFIGURE.
-
- See the INSTALL file for general information regarding Configure.
- Only Solaris-specific issues are discussed here. Usually, the
- defaults should be fine.
-
- =head2 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.
-
- =head3 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 L<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.
-
- =head3 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.
-
- =head3 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.
-
- =head3 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).
-
- =head2 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.
-
- =head2 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.]
-
- =head1 MAKE PROBLEMS.
-
- =over 4
-
- =item 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
- L<"GNU as and GNU ld"> above.
-
- =item 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
- L<"GNU as and GNU ld">.
-
- =item 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
- L<"LD_LIBRARY_PATH"> above.
-
- =item #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.
-
- =item 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.
-
- =back
-
- =head1 MAKE TEST
-
- =head2 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.
-
- =head2 nss_delete core dump from op/pwent or op/grent
-
- See L<perlhpux/"nss_delete core dump from op/pwent or op/grent">.
-
- =head1 PREBUILT BINARIES OF PERL FOR SOLARIS.
-
- You can pick up prebuilt binaries for Solaris from
- L<http://www.sunfreeware.com/>, L<http://www.blastwave.org>,
- ActiveState L<http://www.activestate.com/>, and
- L<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.
-
- =head1 RUNTIME ISSUES FOR PERL ON SOLARIS.
-
- =head2 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 L<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.
-
- =head1 SOLARIS-SPECIFIC MODULES.
-
- See the modules under the Solaris:: and Sun::Solaris namespaces on CPAN,
- see L<http://www.cpan.org/modules/by-module/Solaris/> and
- L<http://www.cpan.org/modules/by-module/Sun/>.
-
- =head1 SOLARIS-SPECIFIC PROBLEMS WITH MODULES.
-
- =head2 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.
-
- =head2 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.
-
- =head2 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
- L<http://www.cosy.sbg.ac.at/~andi/>. If you use SUNWski, make a
- symbolic link /dev/urandom pointing to /dev/random.
-
- It may be possible to use the Entropy Gathering Daemon (written in
- Perl!), available from L<http://www.lothar.com/tech/crypto/>.
-
- =head1 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
- F<lib/Tie/File/t/09_gen_rs> 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 "0"
- which should after a little squinting look very odd indeed.
- Another example is earlier in F<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 C<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.
