490 | Here are some notes kindly contributed by Dean Roehrich. | |
491 | ||
492 | ----- | |
493 | Generic 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 | ||
506 | Here are the gcc-related questions and answers from the Solaris 2 FAQ. Note | |
507 | the themes: | |
508 | - run fixincludes | |
509 | - run fixincludes correctly | |
510 | - don't use GNU as or GNU ld | |
511 | ||
512 | Question 5.7 covers the __builtin_va_alist problem people are always seeing. | |
513 | Question 6.1.3 covers the GNU as and GNU ld issues which are always biting | |
514 | people. | |
515 | Question 6.9 is for those who are still trying to compile Perl4. | |
516 | ||
517 | The latest Solaris 2 FAQ can be found in the following locations: | |
518 | rtfm.mit.edu:/pub/usenet-by-group/comp.sys.sun.admin | |
519 | ftp.fwi.uva.nl:/pub/solaris | |
520 | ||
521 | Perl5 comes with a script in the top-level directory called "myconfig" which | |
522 | will print a summary of the configuration in your config.sh. My summary for | |
523 | Solaris 2.4 and gcc 2.6.3 follows. I have also built with gcc 2.7.0 and the | |
524 | results are identical. This configuration was generated with Configure's -d | |
525 | option (take all defaults, don't bother prompting me). All tests pass for | |
526 | Perl5.001, patch.1m. | |

557 | From: Casper.Dik@Holland.Sun.COM (Casper H.S. Dik - Network Security Engineer) | |
558 | Subject: Solaris 2 Frequently Asked Questions (FAQ) 1.48 | |
559 | Date: 25 Jul 1995 12:20:18 GMT | |
560 | ||
561 | 5.7) 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 | ||
573 | 6.1) 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 | ||
592 | 6.9) 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. | |

618 | 7.0) 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 | |
659 | > Solaris 8, there are 463 executables under /usr/bin, but only 15 of | |
660 | > those require 64 bit versions - mainly because they invade the kernel | |
661 | > address space, e.g. adb, kgmon etc. Certainly we don't recommend users | |
662 | > to build 64 bit apps unless they need the address space. | |
