516 Here are some notes kindly contributed by Dean Roehrich.
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.
532 Here are the gcc-related questions and answers from the Solaris 2 FAQ. Note
535 - run fixincludes correctly
536 - don't use GNU as or GNU ld
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
541 Question 6.9 is for those who are still trying to compile Perl4.
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
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

584 Subject: Solaris 2 Frequently Asked Questions (FAQ) 1.48
585 Date: 25 Jul 1995 12:20:18 GMT
587 5.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined?
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.
597 Another possible cause is using ``gcc -I/usr/include.''
599 6.1) Where is the C compiler or where can I get one?
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.
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.
618 6.9) I can't get perl 4.036 to compile or run.
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)
626 Some questions need a special answer.
628 Are your system (especially dbm) libraries compiled with gcc? [y] y
630 yes: gcc 2.3.3 or later uses the standard calling
631 conventions, same as Sun's C.
633 Any additional cc flags? [ -traditional -Dvolatile=__volatile__
634 -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__
635 Remove /usr/ucbinclude.
637 Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm
638 -lucb] -lsocket -lnsl -lm
640 Don't include -ldbm, -lmalloc and -lucb.
642 Perl 5 compiled out of the box.
644 7.0) 64-bitness, from Alan Burlison (added by jhi 2000-02-21)
646 You need a machine running Solaris 2.7 or above.
650 1. Solaris 2.7 and above will run in either 32 bit or 64 bit mode,
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
