It is written in the POD format (see pod/perlpod.pod) which is +specifically designed to be readable as is. + +=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 Some issues relating to the older SunOS 4.x are +also discussed, though they may be out of date.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 probably OK, as most perl +scripts shipped with Solaris use an explicit path. (There are a few +exceptions, such as /usr/bin/rpm2cpio and /etc/rcm/scripts/README, but +these are also sufficiently generic that the actual version of perl +probably doesn't matter too much.) + +Solaris ships with a range of Solaris-specific modules. If you choose +to install your own version of perl you will find the source of many of +these modules is available on CPAN under the Sun::Solaris:: namespace. + +Solaris may include two versions of perl, e.g. Solaris 9 includes +both 5.005_03 and 5.6.1. This is to provide stability across Solaris +releases, in cases where a later perl version has incompatibilities +with the version included in the 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. 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 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: + + Failed Test Stat Wstat Total Fail Failed List of Failed + ----------------------------------------------------------------------------- + ... + ../ext/Encode/t/at-cn.t 4 1024 29 4 13.79% 14-17 + ../ext/Encode/t/at-tw.t 10 2560 17 10 58.82% 2 4 6 8 10 12 + 14-17 + ../ext/Encode/t/enc_data.t 29 7424 ?? ?? % ?? + ../ext/Encode/t/enc_eucjp.t 29 7424 ?? ?? % ?? + ../ext/Encode/t/enc_module.t 29 7424 ?? ?? % ?? + ../ext/Encode/t/encoding.t 29 7424 ?? ?? % ?? + ../ext/Encode/t/grow.t 12 3072 24 12 50.00% 2 4 6 8 10 12 14 + 16 18 20 22 24 + Failed Test Stat Wstat Total Fail Failed List of Failed + ------------------------------------------------------------------------------ + ../ext/Encode/t/guess.t 255 65280 29 40 137.93% 10-29 + ../ext/Encode/t/jperl.t 29 7424 15 30 200.00% 1-15 + ../ext/Encode/t/mime-header.t 2 512 10 2 20.00% 2-3 + ../ext/Encode/t/perlio.t 22 5632 38 22 57.89% 1-4 9-16 19-20 + 23-24 27-32 + ../ext/List/Util/t/shuffle.t 0 139 ?? ?? % ?? + ../ext/PerlIO/t/encoding.t 14 1 7.14% 11 + ../ext/PerlIO/t/fallback.t 9 2 22.22% 3 5 + ../ext/Socket/t/socketpair.t 0 2 45 70 155.56% 11-45 + ../lib/CPAN/t/vcmp.t 30 1 3.33% 25 + ../lib/Tie/File/t/09_gen_rs.t 0 15 ?? ?? % ?? + ../lib/Unicode/Collate/t/test.t 199 30 15.08% 7 26-27 71-75 + 81-88 95 101 + 103-104 106 108- + 109 122 124 161 + 169-172 + ../lib/sort.t 0 139 119 26 21.85% 107-119 + op/alarm.t 4 1 25.00% 4 + op/utfhash.t 97 1 1.03% 31 + run/fresh_perl.t 91 1 1.10% 32 + uni/tr_7jis.t ?? ?? % ?? + uni/tr_eucjp.t 29 7424 6 12 200.00% 1-6 + uni/tr_sjis.t 29 7424 6 12 200.00% 1-6 + 56 tests and 467 subtests skipped. + Failed 27/811 test scripts, 96.67% okay. 1383/75399 subtests failed, 98.17% okay. + +The alarm() test failure is caused by system() apparently blocking +alarm().
