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

586 Subject: Solaris 2 Frequently Asked Questions (FAQ) 1.48
587 Date: 25 Jul 1995 12:20:18 GMT
589 5.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined?
591 You're using gcc without properly installing the gcc fixed
592 include files. Or you ran fixincludes after installing gcc
593 w/o moving the gcc supplied varargs.h and stdarg.h files
594 out of the way and moving them back again later. This often
595 happens when people install gcc from a binary distribution.
596 If there's a tmp directory in gcc's include directory, fixincludes
597 didn't complete. You should have run "just-fixinc" instead.
599 Another possible cause is using ``gcc -I/usr/include.''
601 6.1) Where is the C compiler or where can I get one?
607 Gcc is available from the GNU archives in source and binary
608 form. Look in a directory called sparc-sun-solaris2 for
609 binaries. You need gcc 2.3.3 or later. You should not use
610 GNU as or GNU ld. Make sure you run just-fixinc if you use
611 a binary distribution. Better is to get a binary version and
612 use that to bootstrap gcc from source.
616 When you install gcc, don't make the mistake of installing
617 GNU binutils or GNU libc, they are not as capable as their
618 counterparts you get with Solaris 2.x.
620 6.9) I can't get perl 4.036 to compile or run.
622 Run Configure, and use the solaris_2_0 hints, *don't* use
623 the solaris_2_1 hints and don't use the config.sh you may
624 already have. First you must make sure Configure and make
625 don't find /usr/ucb/cc. (It must use gcc or the native C
626 compiler: /opt/SUNWspro/bin/cc)
628 Some questions need a special answer.
630 Are your system (especially dbm) libraries compiled with gcc? [y] y
632 yes: gcc 2.3.3 or later uses the standard calling
633 conventions, same as Sun's C.
635 Any additional cc flags? [ -traditional -Dvolatile=__volatile__
636 -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__
637 Remove /usr/ucbinclude.
639 Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm
640 -lucb] -lsocket -lnsl -lm
642 Don't include -ldbm, -lmalloc and -lucb.
644 Perl 5 compiled out of the box.
646 7.0) 64-bitness, from Alan Burlison (added by jhi 2000-02-21)
648 You need a machine running Solaris 2.7 or above.
652 1. Solaris 2.7 and above will run in either 32 bit or 64 bit mode,
654 2. You can build 64 bit apps whilst running 32 bit mode and vice-versa.
655 3. 32 bit apps will run under Solaris running in either 32 or 64 bit mode.
656 4. 64 bit apps require Solaris to be running 64 bit mode
657 5. It is possible to select the appropriate 32 or 64 bit version of an
658 app at run-time using isaexec(3).
659 6. You can detect the OS mode using "isainfo -v", e.g.
660 fubar$ isainfo -v # Ultra 30 in 64 bit mode
661 64-bit sparcv9 applications
662 32-bit sparc applications
663 7. To compile 64 bit you need to use the flag "-xarch=v9".
664 getconf(1) will tell you this, e.g.
665 fubar$ getconf -a | grep v9
666 XBS5_LP64_OFF64_CFLAGS: -xarch=v9
667 XBS5_LP64_OFF64_LDFLAGS: -xarch=v9
