+.SH NAME
+perlsolaris \- Perl version 5 on Solaris systems
+.SH DESCRIPTION
+.IX Header "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+also discussed, though they may be out of date.
+.PP
+For the most part, everything should just work.
+.PP
+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 \fI/usr/bin/perl\fR pointing to \fI/usr/perl5/bin/perl\fR. 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.
+.PP
+You may wish to put your version of perl in the PATH of all users by
+changing the link \fI/usr/bin/perl\fR. This is probably OK, as most perl
+scripts shipped with Solaris use an explicit path. (There are a few
+exceptions, such as \fI/usr/bin/rpm2cpio\fR and \fI/etc/rcm/scripts/README\fR, but
+these are also sufficiently generic that the actual version of perl
+probably doesn't matter too much.)
+.PP
+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.
+.PP
+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.
+.PP
+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):
+.PP
+.Vb 7
+\& # 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
+.Ve
+.PP
+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.
+.PP
+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.
+.SS "Solaris Version Numbers."
+.IX Subsection "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:
+.PP
+.Vb 7
+\& Sun: perl\*(Aqs 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

+.SS "File Extraction Problems on Solaris."
+.IX Subsection "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.
+.SS "Compiler and Related Tools on Solaris."
+.IX Subsection "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.
+.PP
+\fIInclude /usr/ccs/bin/ in your PATH.\fR
+.IX Subsection "Include /usr/ccs/bin/ in your PATH."
+.PP
+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.
+.PP
+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):
+.PP
+for tools (sccs, lex, yacc, make, nm, truss, ld, as): SUNWbtool,
+SUNWsprot, SUNWtoo
+.PP
+for libraries & headers: SUNWhea, SUNWarc, SUNWlibm, SUNWlibms, SUNWdfbh,
+SUNWcg6h, SUNWxwinc
+.PP
+Additionally, on Solaris 8 and 9 you also need:
+.PP
+for 64 bit development: SUNWarcx, SUNWbtoox, SUNWdplx, SUNWscpux,
+SUNWsprox, SUNWtoox, SUNWlmsx, SUNWlmx, SUNWlibCx
+.PP
+And only on Solaris 8 you also need:
+.PP
+for libraries & headers: SUNWolinc
+.PP
+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
+.PP
+.Vb 1
+\& $ grep /my/missing/file /var/sadm/install/contents
+.Ve
+.PP
+This will display a line like this:
+.PP
+/usr/include/sys/errno.h f none 0644 root bin 7471 37605 956241356 SUNWhea
+.PP
+The last item listed (SUNWhea in this example) is the package you need.
+.PP
+\fIAvoid /usr/ucb/cc.\fR
+.IX Subsection "Avoid /usr/ucb/cc."
+.PP
+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.
+.PP
+\fISun's C Compiler\fR
+.IX Subsection "Sun's C Compiler"
+.PP
+If you use Sun's C compiler, make sure the correct directory
+(usually /opt/SUNWspro/bin/) is in your PATH (before /usr/ucb/).
+.PP
+\fIGCC\fR
+.IX Subsection "GCC"
+.PP
+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.
+.PP
+You must Configure perl with
+.PP
+.Vb 1
+\& $ sh Configure \-Dcc=gcc
+.Ve
+.PP
+If you don't, you may experience strange build errors.
+.PP
+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.
+.PP
+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.
+.PP
+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.
+.PP
+\fIGNU as and GNU ld\fR
+.IX Subsection "GNU as and GNU ld"
+.PP
+The following information applies to gcc version 2. Volunteers to
+update it as appropriately for gcc version 3 would be appreciated.
+.PP
+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.
+.PP
+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.
+.PP
+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:
+.PP
+.Vb 2
+\& ccdlflags="$ccdlflags \-Wl,\-E"
+\& lddlflags="$lddlflags \-Wl,\-E \-G"
+.Ve
+.PP
+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.
+.PP
+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
+.PP
+.Vb 1
+\& $ sh Configure \-Dcc=\*(Aqgcc \-B/usr/ccs/bin/\*(Aq
+.Ve
+.PP
+Note that the trailing slash is required. This will result in some
+harmless warnings as Configure is run:
+.PP
+.Vb 1
+\& gcc: file path prefix \`/usr/ccs/bin/\*(Aq never used
+.Ve
+.PP
+These messages may safely be ignored.
+(Note that for a SunOS4 system, you must use \-B/bin/ instead.)
+.PP
+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.
+.PP
+\fISun and GNU make\fR
+.IX Subsection "Sun and GNU make"
+.PP
+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.
+.PP
+\fIAvoid libucb.\fR
+.IX Subsection "Avoid libucb."
+.PP
+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.
+.SS "Environment for Compiling perl on Solaris"
+.IX Subsection "Environment for Compiling perl on Solaris"
+\fIPATH\fR
+.IX Subsection "PATH"
+.PP
+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.
+.PP
+\fILD_LIBRARY_PATH\fR
+.IX Subsection "LD_LIBRARY_PATH"
+.PP
+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).
+.PP
+If you get an error message
+.PP
+.Vb 1
+\& dlopen: stub interception failed
+.Ve
+.PP
+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.]
+.SH "RUN CONFIGURE."
+.IX Header "RUN CONFIGURE."
+See the INSTALL file for general information regarding Configure.
+Only Solaris-specific issues are discussed here. Usually, the
+defaults should be fine.
+.SS "64\-bit perl on Solaris."
+.IX Subsection "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.
+.PP
+By default, perl\-5.6.0 (or later) is compiled as a 32\-bit application
+with largefile and long-long support.
+.PP
+\fIGeneral 32\-bit vs. 64\-bit issues.\fR
+.IX Subsection "General 32-bit vs. 64-bit issues."
+.PP
+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.
+.PP
+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.
+.PP
+For a more complete explanation of 64\-bit issues, see the
+"Solaris 64\-bit Developer's Guide" at <http://docs.sun.com/>
+.PP
+You can detect the OS mode using "isainfo \-v", e.g.
+.PP
+.Vb 3
+\& $ isainfo \-v # Ultra 30 in 64 bit mode
+\& 64\-bit sparcv9 applications
+\& 32\-bit sparc applications
+.Ve
+.PP
+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.
+.PP
+\fILarge File Support\fR
+.IX Subsection "Large File Support"
+.PP
+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.)
+.PP
+First is the "transitional compilation environment", described in
+\&\fBlfcompile64\fR\|(5). According to the man page,
+.PP
+.Vb 7
+\& 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.
+.Ve
+.PP
+The transitional compilation environment is obtained with the
+following compiler and linker flags:
+.PP
+.Vb 3
+\& getconf LFS64_CFLAGS \-D_LARGEFILE64_SOURCE
+\& getconf LFS64_LDFLAG # nothing special needed
+\& getconf LFS64_LIBS # nothing special needed
+.Ve
+.PP
+Second is the "large file compilation environment", described in
+\&\fBlfcompile\fR\|(5). According to the man page,
+.PP
+.Vb 5
+\& 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.
+.Ve
+.PP
+Two exceptions are \fBfseek()\fR and \fBftell()\fR. 32\-bit applications should
+use fseeko(3C) and ftello(3C). These will get automatically mapped
+to \fBfseeko64()\fR and \fBftello64()\fR.
+.PP
+The large file compilation environment is obtained with
+.PP
+.Vb 3
+\& getconf LFS_CFLAGS \-D_LARGEFILE_SOURCE \-D_FILE_OFFSET_BITS=64
+\& getconf LFS_LDFLAGS # nothing special needed
+\& getconf LFS_LIBS # nothing special needed
+.Ve
+.PP
+By default, perl uses the large file compilation environment and
+relies on Solaris to do the underlying mapping of interfaces.
+.PP
+\fIBuilding an LP64 perl\fR
+.IX Subsection "Building an LP64 perl"
+.PP
+To compile a 64\-bit application on an UltraSparc with a recent Sun Compiler,
+you need to use the flag "\-xarch=v9". \fBgetconf\fR\|(1) will tell you this, e.g.
+.PP
+.Vb 10
+\& $ 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_LDFLAGS: \-xarch=v9
+\& _XBS5_LPBIG_OFFBIG_LINTFLAGS: \-xarch=v9
+.Ve
+.PP
+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.
+.PP
+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:
+.PP
+.Vb 5
+\& 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.

+.IX 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.

+.IX Subsection "Limits on Numbers of Open Files on Solaris."
+The stdio(3C) manpage notes that for LP32 applications, only 255
+files may be opened using \fBfopen()\fR, and only file descriptors 0
+through 255 can be used in a stream. Since perl calls \fBopen()\fR and
+then fdopen(3C) with the resulting file descriptor, perl is limited
+to 255 simultaneous open files, even if \fBsysopen()\fR 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.

+.SS "Proc::ProcessTable on Solaris"
+.IX Subsection "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.
+.PP
+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 \fBproc\fR\|(4) for further
+discussion.
+.PP
+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.
+.SS "BSD::Resource on Solaris"
+.IX Subsection "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.
+.SS "Net::SSLeay on Solaris"
+.IX Subsection "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

+.SH "SunOS 4.x"
+.IX Header "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
+.PP
+.Vb 1
+\& ... relocation truncated to fit: BASE13 ...
+.Ve
+.PP
+and dies. Therefore the SunOS 4.1 hints file explicitly sets the
+ld to be \fI/usr/bin/ld\fR.
+.PP
+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.
+.PP
+Running the test suite in SunOS 4.1 is a bit tricky since the
+\&\fIdist/Tie\-File/t/09_gen_rs.t\fR test hangs (subtest #51, FWIW) for some
+unknown reason. Just stop the test and kill that particular Perl
+process.
+.PP
+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 \fIt/run/fresh_perl\fR where \fBchr\fR\|(0xff) is
+expected but the test fails because the result is \fBchr\fR\|(0xff). Exactly.
+.PP
+This is the "make test" result from the said combination:
