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.
You must use an ANSI C compiler to build perl. Perl can be compiled with either Suns 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
Additionaly, 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.
You dont 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.
Suns C Compiler
If you use Suns C compiler, make sure the correct directory (usually /opt/SUNWspro/bin/) is in your PATH (before /usr/ucb/).
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 dont, 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 gccs 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.
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 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 youll 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 Suns 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.
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.
Make sure your PATH includes the compiler (/opt/SUNWspro/bin/ if youre using Suns 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 doesnt include /usr/ucb or that it includes it after the compiler and compiler tools and other standard Solaris directories. You definitely dont want /usr/ucb/cc.
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.]
See the INSTALL file for general information regarding Configure. Only Solaris-specific issues are discussed here. Usually, the defaults should be fine.
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 Developers 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 dont 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.
As of 5.8.1, long doubles are working if you use the Sun compilers (needed for additional math routines not included in libm).
It is possible to build a threaded version of perl on Solaris. The entire perl thread implementation is still experimental, however, so beware.
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 perls malloc, you can rebuild perl from the sources and Configure the build with
$ sh Configure -Dusemymalloc
You should not use perls 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. Suns compiler appears to be okay with or without perls malloc. [XXX further investigation is needed here.]
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 youre using gcc, its 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.
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.
See nss_delete core dump from op/pwent or op/grent in perlhpux.
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.
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.
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.
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/>.
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 doesnt 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 doesnt try to share off_ts with the rest of perl, or if it does they should be explicitly specified as off64_t.
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 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/>.
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.
Running the test suite in SunOS 4.1 is a bit tricky since the 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 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, dont hold your breath for a fix. In addition to that, dont try anything too Unicode-y, especially with Encode, and you should be fine in SunOS 4.x.
