493Generic notes about building Perl5 on Solaris:
494- Use /usr/ccs/bin/make.
495- If you use GNU make, remove its setgid bit.
496- Remove all instances of *ucb* from your path.
497- Make sure libucb is not in /usr/lib (it should be in /usr/ucblib).
498- Do not use GNU as or GNU ld, or any of GNU binutils or GNU libc.
499- Do not use /usr/ucb/cc.
500- Do not change Configure's default answers, except for the path names.
501- Do not use -lmalloc.
502- Do not build on SunOS 4 and expect it to work properly on SunOS 5.
503- /dev/fd must be mounted if you want set-uid scripts to work.
504
505
506Here are the gcc-related questions and answers from the Solaris 2 FAQ. Note
507the themes:
508 - run fixincludes
509 - run fixincludes correctly
510 - don't use GNU as or GNU ld
511
512Question 5.7 covers the __builtin_va_alist problem people are always seeing.
513Question 6.1.3 covers the GNU as and GNU ld issues which are always biting
514people.
515Question 6.9 is for those who are still trying to compile Perl4.
516
517The latest Solaris 2 FAQ can be found in the following locations:

520
521Perl5 comes with a script in the top-level directory called "myconfig" which
522will print a summary of the configuration in your config.sh. My summary for
523Solaris 2.4 and gcc 2.6.3 follows. I have also built with gcc 2.7.0 and the
524results are identical. This configuration was generated with Configure's -d
525option (take all defaults, don't bother prompting me). All tests pass for
526Perl5.001, patch.1m.

557From: Casper.Dik@Holland.Sun.COM (Casper H.S. Dik - Network Security Engineer)
558Subject: Solaris 2 Frequently Asked Questions (FAQ) 1.48
559Date: 25 Jul 1995 12:20:18 GMT
560
5615.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined?
562
563 You're using gcc without properly installing the gcc fixed
564 include files. Or you ran fixincludes after installing gcc
565 w/o moving the gcc supplied varargs.h and stdarg.h files
566 out of the way and moving them back again later. This often
567 happens when people install gcc from a binary distribution.
568 If there's a tmp directory in gcc's include directory, fixincludes
569 didn't complete. You should have run "just-fixinc" instead.
570
571 Another possible cause is using ``gcc -I/usr/include.''
572
5736.1) Where is the C compiler or where can I get one?
574
575 [...]
576
577 3) Gcc.
578
579 Gcc is available from the GNU archives in source and binary
580 form. Look in a directory called sparc-sun-solaris2 for
581 binaries. You need gcc 2.3.3 or later. You should not use
582 GNU as or GNU ld. Make sure you run just-fixinc if you use
583 a binary distribution. Better is to get a binary version and
584 use that to bootstrap gcc from source.
585
586 [...]
587
588 When you install gcc, don't make the mistake of installing
589 GNU binutils or GNU libc, they are not as capable as their
590 counterparts you get with Solaris 2.x.
591
5926.9) I can't get perl 4.036 to compile or run.
593
594 Run Configure, and use the solaris_2_0 hints, *don't* use
595 the solaris_2_1 hints and don't use the config.sh you may
596 already have. First you must make sure Configure and make
597 don't find /usr/ucb/cc. (It must use gcc or the native C
598 compiler: /opt/SUNWspro/bin/cc)
599
600 Some questions need a special answer.
601
602 Are your system (especially dbm) libraries compiled with gcc? [y] y
603
604 yes: gcc 2.3.3 or later uses the standard calling
605 conventions, same as Sun's C.
606
607 Any additional cc flags? [ -traditional -Dvolatile=__volatile__
608 -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__
609 Remove /usr/ucbinclude.
610
611 Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm
612 -lucb] -lsocket -lnsl -lm
613
614 Don't include -ldbm, -lmalloc and -lucb.

6187.0) 64-bitness, from Alan Burlison (added by jhi 2000-02-21)
619
620 You need a machine running Solaris 2.7 or above.
621
622 Here's some rules:
623
624 1. Solaris 2.7 and above will run in either 32 bit or 64 bit mode,
625 via a reboot.
626 2. You can build 64 bit apps whilst running 32 bit mode and vice-versa.
627 3. 32 bit apps will run under Solaris running in either 32 or 64 bit mode.
628 4. 64 bit apps require Solaris to be running 64 bit mode
629 5. It is possible to select the appropriate 32 or 64 bit version of an
630 app at run-time using isaexec(3).
631 6. You can detect the OS mode using "isainfo -v", e.g.
632 fubar$ isainfo -v # Ultra 30 in 64 bit mode
633 64-bit sparcv9 applications
634 32-bit sparc applications
635 7. To compile 64 bit you need to use the flag "-xarch=v9".
636 getconf(1) will tell you this, e.g.
637 fubar$ getconf -a | grep v9
638 XBS5_LP64_OFF64_CFLAGS: -xarch=v9
639 XBS5_LP64_OFF64_LDFLAGS: -xarch=v9
640 XBS5_LP64_OFF64_LINTFLAGS: -xarch=v9
641 XBS5_LPBIG_OFFBIG_CFLAGS: -xarch=v9
642 XBS5_LPBIG_OFFBIG_LDFLAGS: -xarch=v9
643 XBS5_LPBIG_OFFBIG_LINTFLAGS: -xarch=v9
644 _XBS5_LP64_OFF64_CFLAGS: -xarch=v9
645 _XBS5_LP64_OFF64_LDFLAGS: -xarch=v9
646 _XBS5_LP64_OFF64_LINTFLAGS: -xarch=v9
647 _XBS5_LPBIG_OFFBIG_CFLAGS: -xarch=v9
648 _XBS5_LPBIG_OFFBIG_LDFLAGS: -xarch=v9
649 _XBS5_LPBIG_OFFBIG_LINTFLAGS: -xarch=v9
650
651 > > Now, what should we do, then? Should -Duse64bits in a v9 box cause
652 > > Perl to compiled in v9 mode? Or should we for compatibility stick
653 > > with 32 bit builds and let the people in the know to add the -xarch=v9
654 > > to ccflags (and ldflags?)?
655
656 > I think the second (explicit) mechanism should be the default. Unless
657 > you want to allocate more than ~ 4Gb of memory inside Perl, you don't
658 > need Perl to be a 64-bit app. Put it this way, on a machine running
