512 Here are some notes kindly contributed by Dean Roehrich.
515 Generic notes about building Perl5 on Solaris:
516 - Use /usr/ccs/bin/make.
517 - If you use GNU make, remove its setgid bit.
518 - Remove all instances of *ucb* from your path.
519 - Make sure libucb is not in /usr/lib (it should be in /usr/ucblib).
520 - Do not use GNU as or GNU ld, or any of GNU binutils or GNU libc.
521 - Do not use /usr/ucb/cc.
522 - Do not change Configure's default answers, except for the path names.
523 - Do not use -lmalloc.
524 - Do not build on SunOS 4 and expect it to work properly on SunOS 5.
525 - /dev/fd must be mounted if you want set-uid scripts to work.
528 Here are the gcc-related questions and answers from the Solaris 2 FAQ. Note
531 - run fixincludes correctly
532 - don't use GNU as or GNU ld
534 Question 5.7 covers the __builtin_va_alist problem people are always seeing.
535 Question 6.1.3 covers the GNU as and GNU ld issues which are always biting
537 Question 6.9 is for those who are still trying to compile Perl4.
539 The latest Solaris 2 FAQ can be found in the following locations:

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

580 Subject: Solaris 2 Frequently Asked Questions (FAQ) 1.48
581 Date: 25 Jul 1995 12:20:18 GMT
583 5.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined?
585 You're using gcc without properly installing the gcc fixed
586 include files. Or you ran fixincludes after installing gcc
587 w/o moving the gcc supplied varargs.h and stdarg.h files
588 out of the way and moving them back again later. This often
589 happens when people install gcc from a binary distribution.
590 If there's a tmp directory in gcc's include directory, fixincludes
591 didn't complete. You should have run "just-fixinc" instead.
593 Another possible cause is using ``gcc -I/usr/include.''
595 6.1) Where is the C compiler or where can I get one?
601 Gcc is available from the GNU archives in source and binary
602 form. Look in a directory called sparc-sun-solaris2 for
603 binaries. You need gcc 2.3.3 or later. You should not use
604 GNU as or GNU ld. Make sure you run just-fixinc if you use
605 a binary distribution. Better is to get a binary version and
606 use that to bootstrap gcc from source.
610 When you install gcc, don't make the mistake of installing
611 GNU binutils or GNU libc, they are not as capable as their
612 counterparts you get with Solaris 2.x.
614 6.9) I can't get perl 4.036 to compile or run.
616 Run Configure, and use the solaris_2_0 hints, *don't* use
617 the solaris_2_1 hints and don't use the config.sh you may
618 already have. First you must make sure Configure and make
619 don't find /usr/ucb/cc. (It must use gcc or the native C
620 compiler: /opt/SUNWspro/bin/cc)
622 Some questions need a special answer.
624 Are your system (especially dbm) libraries compiled with gcc? [y] y
626 yes: gcc 2.3.3 or later uses the standard calling
627 conventions, same as Sun's C.
629 Any additional cc flags? [ -traditional -Dvolatile=__volatile__
630 -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__
631 Remove /usr/ucbinclude.
633 Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm
634 -lucb] -lsocket -lnsl -lm
636 Don't include -ldbm, -lmalloc and -lucb.
638 Perl 5 compiled out of the box.
640 7.0) 64-bitness, from Alan Burlison (added by jhi 2000-02-21)
642 You need a machine running Solaris 2.7 or above.
646 1. Solaris 2.7 and above will run in either 32 bit or 64 bit mode,
648 2. You can build 64 bit apps whilst running 32 bit mode and vice-versa.
649 3. 32 bit apps will run under Solaris running in either 32 or 64 bit mode.
650 4. 64 bit apps require Solaris to be running 64 bit mode
651 5. It is possible to select the appropriate 32 or 64 bit version of an
652 app at run-time using isaexec(3).
653 6. You can detect the OS mode using "isainfo -v", e.g.
654 fubar$ isainfo -v # Ultra 30 in 64 bit mode
655 64-bit sparcv9 applications
656 32-bit sparc applications
657 7. To compile 64 bit you need to use the flag "-xarch=v9".
658 getconf(1) will tell you this, e.g.
659 fubar$ getconf -a | grep v9
660 XBS5_LP64_OFF64_CFLAGS: -xarch=v9
661 XBS5_LP64_OFF64_LDFLAGS: -xarch=v9
