8 | # you are using gcc, be sure that you are NOT using GNU as and ld. One |

516 | Here are some notes kindly contributed by Dean Roehrich. |
517 | |
518 | ----- |
519 | Generic notes about building Perl5 on Solaris: |
520 | - Use /usr/ccs/bin/make. |
521 | - If you use GNU make, remove its setgid bit. |
522 | - Remove all instances of *ucb* from your path. |
523 | - Make sure libucb is not in /usr/lib (it should be in /usr/ucblib). |
524 | - Do not use GNU as or GNU ld, or any of GNU binutils or GNU libc. |
525 | - Do not use /usr/ucb/cc. |
526 | - Do not change Configure's default answers, except for the path names. |
527 | - Do not use -lmalloc. |
528 | - Do not build on SunOS 4 and expect it to work properly on SunOS 5. |
529 | - /dev/fd must be mounted if you want set-uid scripts to work. |
530 | |
531 | |
532 | Here are the gcc-related questions and answers from the Solaris 2 FAQ. Note |
533 | the themes: |
534 | - run fixincludes |
535 | - run fixincludes correctly |
536 | - don't use GNU as or GNU ld |
537 | |
538 | Question 5.7 covers the __builtin_va_alist problem people are always seeing. |
539 | Question 6.1.3 covers the GNU as and GNU ld issues which are always biting |
540 | people. |
541 | Question 6.9 is for those who are still trying to compile Perl4. |
542 | |
543 | The latest Solaris 2 FAQ can be found in the following locations: |
544 | rtfm.mit.edu:/pub/usenet-by-group/comp.sys.sun.admin |
545 | ftp.fwi.uva.nl:/pub/solaris |
546 | |
547 | Perl5 comes with a script in the top-level directory called "myconfig" which |
548 | will print a summary of the configuration in your config.sh. My summary for |
549 | Solaris 2.4 and gcc 2.6.3 follows. I have also built with gcc 2.7.0 and the |
550 | results are identical. This configuration was generated with Configure's -d |
551 | option (take all defaults, don't bother prompting me). All tests pass for |
552 | Perl5.001, patch.1m. |
553 | |
554 | Summary of my perl5 (patchlevel 1) configuration: |

583 | From: Casper.Dik@Holland.Sun.COM (Casper H.S. Dik - Network Security Engineer) |
584 | Subject: Solaris 2 Frequently Asked Questions (FAQ) 1.48 |
585 | Date: 25 Jul 1995 12:20:18 GMT |
586 | |
587 | 5.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined? |
588 | |
589 | You're using gcc without properly installing the gcc fixed |
590 | include files. Or you ran fixincludes after installing gcc |
591 | w/o moving the gcc supplied varargs.h and stdarg.h files |
592 | out of the way and moving them back again later. This often |
593 | happens when people install gcc from a binary distribution. |
594 | If there's a tmp directory in gcc's include directory, fixincludes |
595 | didn't complete. You should have run "just-fixinc" instead. |
596 | |
597 | Another possible cause is using ``gcc -I/usr/include.'' |
598 | |
599 | 6.1) Where is the C compiler or where can I get one? |
600 | |
601 | [...] |
602 | |
603 | 3) Gcc. |
604 | |
605 | Gcc is available from the GNU archives in source and binary |
606 | form. Look in a directory called sparc-sun-solaris2 for |
607 | binaries. You need gcc 2.3.3 or later. You should not use |
608 | GNU as or GNU ld. Make sure you run just-fixinc if you use |
609 | a binary distribution. Better is to get a binary version and |
610 | use that to bootstrap gcc from source. |
611 | |
612 | [...] |
613 | |
614 | When you install gcc, don't make the mistake of installing |
615 | GNU binutils or GNU libc, they are not as capable as their |
616 | counterparts you get with Solaris 2.x. |
617 | |
618 | 6.9) I can't get perl 4.036 to compile or run. |
619 | |
620 | Run Configure, and use the solaris_2_0 hints, *don't* use |
621 | the solaris_2_1 hints and don't use the config.sh you may |
622 | already have. First you must make sure Configure and make |
623 | don't find /usr/ucb/cc. (It must use gcc or the native C |
624 | compiler: /opt/SUNWspro/bin/cc) |
625 | |
626 | Some questions need a special answer. |
627 | |
628 | Are your system (especially dbm) libraries compiled with gcc? [y] y |
629 | |
630 | yes: gcc 2.3.3 or later uses the standard calling |
631 | conventions, same as Sun's C. |
632 | |
633 | Any additional cc flags? [ -traditional -Dvolatile=__volatile__ |
634 | -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__ |
635 | Remove /usr/ucbinclude. |
636 | |
637 | Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm |
638 | -lucb] -lsocket -lnsl -lm |
639 | |
640 | Don't include -ldbm, -lmalloc and -lucb. |
641 | |
642 | Perl 5 compiled out of the box. |

644 | 7.0) 64-bitness, from Alan Burlison (added by jhi 2000-02-21) |
645 | |
646 | You need a machine running Solaris 2.7 or above. |
647 | |
648 | Here's some rules: |
649 | |
650 | 1. Solaris 2.7 and above will run in either 32 bit or 64 bit mode, |
651 | via a reboot. |
652 | 2. You can build 64 bit apps whilst running 32 bit mode and vice-versa. |
653 | 3. 32 bit apps will run under Solaris running in either 32 or 64 bit mode. |
654 | 4. 64 bit apps require Solaris to be running 64 bit mode |
655 | 5. It is possible to select the appropriate 32 or 64 bit version of an |
656 | app at run-time using isaexec(3). |
657 | 6. You can detect the OS mode using "isainfo -v", e.g. |
658 | fubar$ isainfo -v # Ultra 30 in 64 bit mode |
659 | 64-bit sparcv9 applications |
660 | 32-bit sparc applications |
661 | 7. To compile 64 bit you need to use the flag "-xarch=v9". |
662 | getconf(1) will tell you this, e.g. |
663 | fubar$ getconf -a | grep 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 | _XBS5_LP64_OFF64_CFLAGS: -xarch=v9 |
671 | _XBS5_LP64_OFF64_LDFLAGS: -xarch=v9 |
672 | _XBS5_LP64_OFF64_LINTFLAGS: -xarch=v9 |
673 | _XBS5_LPBIG_OFFBIG_CFLAGS: -xarch=v9 |
674 | _XBS5_LPBIG_OFFBIG_LDFLAGS: -xarch=v9 |
675 | _XBS5_LPBIG_OFFBIG_LINTFLAGS: -xarch=v9 |
676 | |
677 | > > Now, what should we do, then? Should -Duse64bits in a v9 box cause |
678 | > > Perl to compiled in v9 mode? Or should we for compatibility stick |
679 | > > with 32 bit builds and let the people in the know to add the -xarch=v9 |
680 | > > to ccflags (and ldflags?)? |
681 | |
682 | > I think the second (explicit) mechanism should be the default. Unless |
683 | > you want to allocate more than ~ 4Gb of memory inside Perl, you don't |
684 | > need Perl to be a 64-bit app. Put it this way, on a machine running |
685 | > Solaris 8, there are 463 executables under /usr/bin, but only 15 of |
686 | > those require 64 bit versions - mainly because they invade the kernel |
687 | > address space, e.g. adb, kgmon etc. Certainly we don't recommend users |
688 | > to build 64 bit apps unless they need the address space. |
