380Here are some notes kindly contributed by Dean Roehrich.
381
382-----
383Generic notes about building Perl5 on Solaris:
384- Use /usr/ccs/bin/make.
385- If you use GNU make, remove its setgid bit.
386- Remove all instances of *ucb* from your path.
387- Make sure libucb is not in /usr/lib (it should be in /usr/ucblib).
388- Do not use GNU as or GNU ld, or any of GNU binutils or GNU libc.
389- Do not use /usr/ucb/cc.
390- Do not change Configure's default answers, except for the path names.
391- Do not use -lmalloc.
392- Do not build on SunOS 4 and expect it to work properly on SunOS 5.
393- /dev/fd must be mounted if you want set-uid scripts to work.
394
395
396Here are the gcc-related questions and answers from the Solaris 2 FAQ. Note
397the themes:
398 - run fixincludes
399 - run fixincludes correctly
400 - don't use GNU as or GNU ld
401
402Question 5.7 covers the __builtin_va_alist problem people are always seeing.
403Question 6.1.3 covers the GNU as and GNU ld issues which are always biting
404people.
405Question 6.9 is for those who are still trying to compile Perl4.
406
407The latest Solaris 2 FAQ can be found in the following locations:
408 rtfm.mit.edu:/pub/usenet-by-group/comp.sys.sun.admin
409 ftp.fwi.uva.nl:/pub/solaris

411Perl5 comes with a script in the top-level directory called "myconfig" which
412will print a summary of the configuration in your config.sh. My summary for
413Solaris 2.4 and gcc 2.6.3 follows. I have also built with gcc 2.7.0 and the
414results are identical. This configuration was generated with Configure's -d
415option (take all defaults, don't bother prompting me). All tests pass for
416Perl5.001, patch.1m.

4515.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined?
452
453 You're using gcc without properly installing the gcc fixed
454 include files. Or you ran fixincludes after installing gcc
455 w/o moving the gcc supplied varargs.h and stdarg.h files
456 out of the way and moving them back again later. This often
457 happens when people install gcc from a binary distribution.
458 If there's a tmp directory in gcc's include directory, fixincludes
459 didn't complete. You should have run "just-fixinc" instead.
460
461 Another possible cause is using ``gcc -I/usr/include.''
462
4636.1) Where is the C compiler or where can I get one?
464
465 [...]
466
467 3) Gcc.
468
469 Gcc is available from the GNU archives in source and binary
470 form. Look in a directory called sparc-sun-solaris2 for
471 binaries. You need gcc 2.3.3 or later. You should not use
472 GNU as or GNU ld. Make sure you run just-fixinc if you use
473 a binary distribution. Better is to get a binary version and
474 use that to bootstrap gcc from source.
475
476 [...]
477
478 When you install gcc, don't make the mistake of installing
479 GNU binutils or GNU libc, they are not as capable as their
480 counterparts you get with Solaris 2.x.
481
4826.9) I can't get perl 4.036 to compile or run.
483
484 Run Configure, and use the solaris_2_0 hints, *don't* use
485 the solaris_2_1 hints and don't use the config.sh you may
486 already have. First you must make sure Configure and make
487 don't find /usr/ucb/cc. (It must use gcc or the native C
488 compiler: /opt/SUNWspro/bin/cc)
489
490 Some questions need a special answer.
491
492 Are your system (especially dbm) libraries compiled with gcc? [y] y
493
494 yes: gcc 2.3.3 or later uses the standard calling
495 conventions, same as Sun's C.
496
497 Any additional cc flags? [ -traditional -Dvolatile=__volatile__
498 -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__
499 Remove /usr/ucbinclude.
500
501 Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm
502 -lucb] -lsocket -lnsl -lm
503
504 Don't include -ldbm, -lmalloc and -lucb.
505
506 Perl 5 compiled out of the box.

5087.0) 64-bitness, from Alan Burlison (added by jhi 2000-02-21)
509
510 You need a machine running Solaris 2.7 or above.
511
512 Here's some rules:
513
514 1. Solaris 2.7 and above will run in either 32 bit or 64 bit mode,
515 via a reboot.
516 2. You can build 64 bit apps whilst running 32 bit mode and vice-versa.
517 3. 32 bit apps will run under Solaris running in either 32 or 64 bit mode.
518 4. 64 bit apps require Solaris to be running 64 bit mode
519 5. It is possible to select the appropriate 32 or 64 bit version of an
520 app at run-time using isaexec(3).
521 6. You can detect the OS mode using "isainfo -v", e.g.
522 fubar$ isainfo -v # Ultra 30 in 64 bit mode
523 64-bit sparcv9 applications
524 32-bit sparc applications
525 7. To compile 64 bit you need to use the flag "-xarch=v9".
526 getconf(1) will tell you this, e.g.
527 fubar$ getconf -a | grep v9
528 XBS5_LP64_OFF64_CFLAGS: -xarch=v9
529 XBS5_LP64_OFF64_LDFLAGS: -xarch=v9
530 XBS5_LP64_OFF64_LINTFLAGS: -xarch=v9
531 XBS5_LPBIG_OFFBIG_CFLAGS: -xarch=v9
532 XBS5_LPBIG_OFFBIG_LDFLAGS: -xarch=v9
533 XBS5_LPBIG_OFFBIG_LINTFLAGS: -xarch=v9
534 _XBS5_LP64_OFF64_CFLAGS: -xarch=v9
535 _XBS5_LP64_OFF64_LDFLAGS: -xarch=v9
536 _XBS5_LP64_OFF64_LINTFLAGS: -xarch=v9
537 _XBS5_LPBIG_OFFBIG_CFLAGS: -xarch=v9
538 _XBS5_LPBIG_OFFBIG_LDFLAGS: -xarch=v9
539 _XBS5_LPBIG_OFFBIG_LINTFLAGS: -xarch=v9
