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

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

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

642 7.0) 64-bitness, from Alan Burlison (added by jhi 2000-02-21)
644 You need a machine running Solaris 2.7 or above.
648 1. Solaris 2.7 and above will run in either 32 bit or 64 bit mode,
650 2. You can build 64 bit apps whilst running 32 bit mode and vice-versa.
651 3. 32 bit apps will run under Solaris running in either 32 or 64 bit mode.
652 4. 64 bit apps require Solaris to be running 64 bit mode
653 5. It is possible to select the appropriate 32 or 64 bit version of an
654 app at run-time using isaexec(3).
655 6. You can detect the OS mode using "isainfo -v", e.g.
656 fubar$ isainfo -v # Ultra 30 in 64 bit mode
657 64-bit sparcv9 applications
658 32-bit sparc applications
659 7. To compile 64 bit you need to use the flag "-xarch=v9".
660 getconf(1) will tell you this, e.g.
661 fubar$ getconf -a | grep v9
