510Here are some notes kindly contributed by Dean Roehrich.

512-----
513Generic notes about building Perl5 on Solaris:
514- Use /usr/ccs/bin/make.
515- If you use GNU make, remove its setgid bit.
516- Remove all instances of *ucb* from your path.
517- Make sure libucb is not in /usr/lib (it should be in /usr/ucblib).
518- Do not use GNU as or GNU ld, or any of GNU binutils or GNU libc.
519- Do not use /usr/ucb/cc.
520- Do not change Configure's default answers, except for the path names.
521- Do not use -lmalloc.
522- Do not build on SunOS 4 and expect it to work properly on SunOS 5.
523- /dev/fd must be mounted if you want set-uid scripts to work.
524
525
526Here are the gcc-related questions and answers from the Solaris 2 FAQ. Note
527the themes:
528 - run fixincludes
529 - run fixincludes correctly
530 - don't use GNU as or GNU ld
531
532Question 5.7 covers the __builtin_va_alist problem people are always seeing.
533Question 6.1.3 covers the GNU as and GNU ld issues which are always biting
534people.
535Question 6.9 is for those who are still trying to compile Perl4.
536
537The latest Solaris 2 FAQ can be found in the following locations:

541Perl5 comes with a script in the top-level directory called "myconfig" which
542will print a summary of the configuration in your config.sh. My summary for
543Solaris 2.4 and gcc 2.6.3 follows. I have also built with gcc 2.7.0 and the
544results are identical. This configuration was generated with Configure's -d
545option (take all defaults, don't bother prompting me). All tests pass for
546Perl5.001, patch.1m.

577From: Casper.Dik@Holland.Sun.COM (Casper H.S. Dik - Network Security Engineer)
578Subject: Solaris 2 Frequently Asked Questions (FAQ) 1.48
579Date: 25 Jul 1995 12:20:18 GMT
580
5815.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined?
582
583 You're using gcc without properly installing the gcc fixed
584 include files. Or you ran fixincludes after installing gcc
585 w/o moving the gcc supplied varargs.h and stdarg.h files
586 out of the way and moving them back again later. This often
587 happens when people install gcc from a binary distribution.
588 If there's a tmp directory in gcc's include directory, fixincludes
589 didn't complete. You should have run "just-fixinc" instead.
590
591 Another possible cause is using ``gcc -I/usr/include.''
592
5936.1) Where is the C compiler or where can I get one?
594
595 [...]
596
597 3) Gcc.
598
599 Gcc is available from the GNU archives in source and binary
600 form. Look in a directory called sparc-sun-solaris2 for
601 binaries. You need gcc 2.3.3 or later. You should not use
602 GNU as or GNU ld. Make sure you run just-fixinc if you use
603 a binary distribution. Better is to get a binary version and
604 use that to bootstrap gcc from source.
605
606 [...]
607
608 When you install gcc, don't make the mistake of installing
609 GNU binutils or GNU libc, they are not as capable as their
610 counterparts you get with Solaris 2.x.
611
6126.9) I can't get perl 4.036 to compile or run.
613
614 Run Configure, and use the solaris_2_0 hints, *don't* use
615 the solaris_2_1 hints and don't use the config.sh you may
616 already have. First you must make sure Configure and make
617 don't find /usr/ucb/cc. (It must use gcc or the native C
618 compiler: /opt/SUNWspro/bin/cc)
619
620 Some questions need a special answer.
621
622 Are your system (especially dbm) libraries compiled with gcc? [y] y
623
624 yes: gcc 2.3.3 or later uses the standard calling
625 conventions, same as Sun's C.
626
627 Any additional cc flags? [ -traditional -Dvolatile=__volatile__
628 -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__
629 Remove /usr/ucbinclude.
630
631 Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm
632 -lucb] -lsocket -lnsl -lm
633
634 Don't include -ldbm, -lmalloc and -lucb.

6387.0) 64-bitness, from Alan Burlison (added by jhi 2000-02-21)
639
640 You need a machine running Solaris 2.7 or above.
641
642 Here's some rules:
643
644 1. Solaris 2.7 and above will run in either 32 bit or 64 bit mode,
645 via a reboot.
646 2. You can build 64 bit apps whilst running 32 bit mode and vice-versa.
647 3. 32 bit apps will run under Solaris running in either 32 or 64 bit mode.
648 4. 64 bit apps require Solaris to be running 64 bit mode
649 5. It is possible to select the appropriate 32 or 64 bit version of an
650 app at run-time using isaexec(3).
651 6. You can detect the OS mode using "isainfo -v", e.g.
652 fubar$ isainfo -v # Ultra 30 in 64 bit mode
653 64-bit sparcv9 applications
654 32-bit sparc applications
655 7. To compile 64 bit you need to use the flag "-xarch=v9".
656 getconf(1) will tell you this, e.g.
657 fubar$ getconf -a | grep v9
658 XBS5_LP64_OFF64_CFLAGS: -xarch=v9
659 XBS5_LP64_OFF64_LDFLAGS: -xarch=v9
660 XBS5_LP64_OFF64_LINTFLAGS: -xarch=v9
661 XBS5_LPBIG_OFFBIG_CFLAGS: -xarch=v9
662 XBS5_LPBIG_OFFBIG_LDFLAGS: -xarch=v9
663 XBS5_LPBIG_OFFBIG_LINTFLAGS: -xarch=v9
664 _XBS5_LP64_OFF64_CFLAGS: -xarch=v9
665 _XBS5_LP64_OFF64_LDFLAGS: -xarch=v9
666 _XBS5_LP64_OFF64_LINTFLAGS: -xarch=v9
667 _XBS5_LPBIG_OFFBIG_CFLAGS: -xarch=v9
668 _XBS5_LPBIG_OFFBIG_LDFLAGS: -xarch=v9
669 _XBS5_LPBIG_OFFBIG_LINTFLAGS: -xarch=v9
670
671 > > Now, what should we do, then? Should -Duse64bits in a v9 box cause
672 > > Perl to compiled in v9 mode? Or should we for compatibility stick
673 > > with 32 bit builds and let the people in the know to add the -xarch=v9
674 > > to ccflags (and ldflags?)?
675
676 > I think the second (explicit) mechanism should be the default. Unless
677 > you want to allocate more than ~ 4Gb of memory inside Perl, you don't
678 > need Perl to be a 64-bit app. Put it this way, on a machine running
679 > Solaris 8, there are 463 executables under /usr/bin, but only 15 of
680 > those require 64 bit versions - mainly because they invade the kernel
681 > address space, e.g. adb, kgmon etc. Certainly we don't recommend users
