437Generic notes about building Perl5 on Solaris:
438- Use /usr/ccs/bin/make.
439- If you use GNU make, remove its setgid bit.
440- Remove all instances of *ucb* from your path.
441- Make sure libucb is not in /usr/lib (it should be in /usr/ucblib).
442- Do not use GNU as or GNU ld, or any of GNU binutils or GNU libc.
443- Do not use /usr/ucb/cc.
444- Do not change Configure's default answers, except for the path names.
445- Do not use -lmalloc.
446- Do not build on SunOS 4 and expect it to work properly on SunOS 5.
447- /dev/fd must be mounted if you want set-uid scripts to work.

450Here are the gcc-related questions and answers from the Solaris 2 FAQ. Note
451the themes:
452 - run fixincludes
453 - run fixincludes correctly
454 - don't use GNU as or GNU ld
455
456Question 5.7 covers the __builtin_va_alist problem people are always seeing.
457Question 6.1.3 covers the GNU as and GNU ld issues which are always biting
458people.
459Question 6.9 is for those who are still trying to compile Perl4.
460
461The latest Solaris 2 FAQ can be found in the following locations:

463 ftp.fwi.uva.nl:/pub/solaris
464
465Perl5 comes with a script in the top-level directory called "myconfig" which
466will print a summary of the configuration in your config.sh. My summary for
467Solaris 2.4 and gcc 2.6.3 follows. I have also built with gcc 2.7.0 and the
468results are identical. This configuration was generated with Configure's -d
469option (take all defaults, don't bother prompting me). All tests pass for
470Perl5.001, patch.1m.

501From: Casper.Dik@Holland.Sun.COM (Casper H.S. Dik - Network Security Engineer)
502Subject: Solaris 2 Frequently Asked Questions (FAQ) 1.48
503Date: 25 Jul 1995 12:20:18 GMT
504
5055.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined?
506
507 You're using gcc without properly installing the gcc fixed
508 include files. Or you ran fixincludes after installing gcc
509 w/o moving the gcc supplied varargs.h and stdarg.h files
510 out of the way and moving them back again later. This often
511 happens when people install gcc from a binary distribution.
512 If there's a tmp directory in gcc's include directory, fixincludes
513 didn't complete. You should have run "just-fixinc" instead.
514
515 Another possible cause is using ``gcc -I/usr/include.''
516
5176.1) Where is the C compiler or where can I get one?
518
519 [...]
520
521 3) Gcc.
522
523 Gcc is available from the GNU archives in source and binary
524 form. Look in a directory called sparc-sun-solaris2 for
525 binaries. You need gcc 2.3.3 or later. You should not use
526 GNU as or GNU ld. Make sure you run just-fixinc if you use
527 a binary distribution. Better is to get a binary version and
528 use that to bootstrap gcc from source.
529
530 [...]
531
532 When you install gcc, don't make the mistake of installing
533 GNU binutils or GNU libc, they are not as capable as their
534 counterparts you get with Solaris 2.x.
535
5366.9) I can't get perl 4.036 to compile or run.
537
538 Run Configure, and use the solaris_2_0 hints, *don't* use
539 the solaris_2_1 hints and don't use the config.sh you may
540 already have. First you must make sure Configure and make
541 don't find /usr/ucb/cc. (It must use gcc or the native C
542 compiler: /opt/SUNWspro/bin/cc)
543
544 Some questions need a special answer.
545
546 Are your system (especially dbm) libraries compiled with gcc? [y] y
547
548 yes: gcc 2.3.3 or later uses the standard calling
549 conventions, same as Sun's C.
550
551 Any additional cc flags? [ -traditional -Dvolatile=__volatile__
552 -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__
553 Remove /usr/ucbinclude.
554
555 Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm
556 -lucb] -lsocket -lnsl -lm
557
558 Don't include -ldbm, -lmalloc and -lucb.

5627.0) 64-bitness, from Alan Burlison (added by jhi 2000-02-21)
563
564 You need a machine running Solaris 2.7 or above.
565
566 Here's some rules:
567
568 1. Solaris 2.7 and above will run in either 32 bit or 64 bit mode,
569 via a reboot.
570 2. You can build 64 bit apps whilst running 32 bit mode and vice-versa.
571 3. 32 bit apps will run under Solaris running in either 32 or 64 bit mode.
572 4. 64 bit apps require Solaris to be running 64 bit mode
573 5. It is possible to select the appropriate 32 or 64 bit version of an
574 app at run-time using isaexec(3).
575 6. You can detect the OS mode using "isainfo -v", e.g.
576 fubar$ isainfo -v # Ultra 30 in 64 bit mode
577 64-bit sparcv9 applications
578 32-bit sparc applications
579 7. To compile 64 bit you need to use the flag "-xarch=v9".
580 getconf(1) will tell you this, e.g.
581 fubar$ getconf -a | grep v9
582 XBS5_LP64_OFF64_CFLAGS: -xarch=v9
583 XBS5_LP64_OFF64_LDFLAGS: -xarch=v9
584 XBS5_LP64_OFF64_LINTFLAGS: -xarch=v9
585 XBS5_LPBIG_OFFBIG_CFLAGS: -xarch=v9
586 XBS5_LPBIG_OFFBIG_LDFLAGS: -xarch=v9
587 XBS5_LPBIG_OFFBIG_LINTFLAGS: -xarch=v9
588 _XBS5_LP64_OFF64_CFLAGS: -xarch=v9
589 _XBS5_LP64_OFF64_LDFLAGS: -xarch=v9
590 _XBS5_LP64_OFF64_LINTFLAGS: -xarch=v9
591 _XBS5_LPBIG_OFFBIG_CFLAGS: -xarch=v9
592 _XBS5_LPBIG_OFFBIG_LDFLAGS: -xarch=v9
593 _XBS5_LPBIG_OFFBIG_LINTFLAGS: -xarch=v9
594
595 > > Now, what should we do, then? Should -Duse64bits in a v9 box cause
596 > > Perl to compiled in v9 mode? Or should we for compatibility stick
597 > > with 32 bit builds and let the people in the know to add the -xarch=v9
598 > > to ccflags (and ldflags?)?
599
600 > I think the second (explicit) mechanism should be the default. Unless
601 > you want to allocate more than ~ 4Gb of memory inside Perl, you don't
602 > need Perl to be a 64-bit app. Put it this way, on a machine running
