478 Here are some notes kindly contributed by Dean Roehrich.
481 Generic notes about building Perl5 on Solaris:
482 - Use /usr/ccs/bin/make.
483 - If you use GNU make, remove its setgid bit.
484 - Remove all instances of *ucb* from your path.
485 - Make sure libucb is not in /usr/lib (it should be in /usr/ucblib).
486 - Do not use GNU as or GNU ld, or any of GNU binutils or GNU libc.
487 - Do not use /usr/ucb/cc.
488 - Do not change Configure's default answers, except for the path names.
489 - Do not use -lmalloc.
490 - Do not build on SunOS 4 and expect it to work properly on SunOS 5.
491 - /dev/fd must be mounted if you want set-uid scripts to work.
494 Here are the gcc-related questions and answers from the Solaris 2 FAQ. Note
497 - run fixincludes correctly
498 - don't use GNU as or GNU ld
500 Question 5.7 covers the __builtin_va_alist problem people are always seeing.
501 Question 6.1.3 covers the GNU as and GNU ld issues which are always biting
503 Question 6.9 is for those who are still trying to compile Perl4.
505 The latest Solaris 2 FAQ can be found in the following locations:
506 rtfm.mit.edu:/pub/usenet-by-group/comp.sys.sun.admin
507 ftp.fwi.uva.nl:/pub/solaris
509 Perl5 comes with a script in the top-level directory called "myconfig" which
510 will print a summary of the configuration in your config.sh. My summary for
511 Solaris 2.4 and gcc 2.6.3 follows. I have also built with gcc 2.7.0 and the
512 results are identical. This configuration was generated with Configure's -d
513 option (take all defaults, don't bother prompting me). All tests pass for

546 Subject: Solaris 2 Frequently Asked Questions (FAQ) 1.48
547 Date: 25 Jul 1995 12:20:18 GMT
549 5.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined?
551 You're using gcc without properly installing the gcc fixed
552 include files. Or you ran fixincludes after installing gcc
553 w/o moving the gcc supplied varargs.h and stdarg.h files
554 out of the way and moving them back again later. This often
555 happens when people install gcc from a binary distribution.
556 If there's a tmp directory in gcc's include directory, fixincludes
557 didn't complete. You should have run "just-fixinc" instead.
559 Another possible cause is using ``gcc -I/usr/include.''
561 6.1) Where is the C compiler or where can I get one?
567 Gcc is available from the GNU archives in source and binary
568 form. Look in a directory called sparc-sun-solaris2 for
569 binaries. You need gcc 2.3.3 or later. You should not use
570 GNU as or GNU ld. Make sure you run just-fixinc if you use
571 a binary distribution. Better is to get a binary version and
572 use that to bootstrap gcc from source.
576 When you install gcc, don't make the mistake of installing
577 GNU binutils or GNU libc, they are not as capable as their
578 counterparts you get with Solaris 2.x.
580 6.9) I can't get perl 4.036 to compile or run.
582 Run Configure, and use the solaris_2_0 hints, *don't* use
583 the solaris_2_1 hints and don't use the config.sh you may
584 already have. First you must make sure Configure and make
585 don't find /usr/ucb/cc. (It must use gcc or the native C
586 compiler: /opt/SUNWspro/bin/cc)
588 Some questions need a special answer.
590 Are your system (especially dbm) libraries compiled with gcc? [y] y
592 yes: gcc 2.3.3 or later uses the standard calling
593 conventions, same as Sun's C.
595 Any additional cc flags? [ -traditional -Dvolatile=__volatile__
596 -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__
597 Remove /usr/ucbinclude.
599 Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm
600 -lucb] -lsocket -lnsl -lm
602 Don't include -ldbm, -lmalloc and -lucb.
604 Perl 5 compiled out of the box.
606 7.0) 64-bitness, from Alan Burlison (added by jhi 2000-02-21)
608 You need a machine running Solaris 2.7 or above.
612 1. Solaris 2.7 and above will run in either 32 bit or 64 bit mode,
614 2. You can build 64 bit apps whilst running 32 bit mode and vice-versa.
615 3. 32 bit apps will run under Solaris running in either 32 or 64 bit mode.
616 4. 64 bit apps require Solaris to be running 64 bit mode
617 5. It is possible to select the appropriate 32 or 64 bit version of an
618 app at run-time using isaexec(3).
619 6. You can detect the OS mode using "isainfo -v", e.g.
620 fubar$ isainfo -v # Ultra 30 in 64 bit mode
621 64-bit sparcv9 applications
622 32-bit sparc applications
623 7. To compile 64 bit you need to use the flag "-xarch=v9".
624 getconf(1) will tell you this, e.g.
625 fubar$ getconf -a | grep v9
626 XBS5_LP64_OFF64_CFLAGS: -xarch=v9
627 XBS5_LP64_OFF64_LDFLAGS: -xarch=v9
