9 # way to do that is to invoke Configure with
11 # sh Configure -Dcc='gcc -B/usr/ccs/bin/'
13 # (Note that the trailing slash is *required*.)

434 Here are some notes kindly contributed by Dean Roehrich.
437 Generic notes about building Perl5 on Solaris:
438 - Use /usr/ccs/bin/make.
439 - If you use GNU make, remove its setgid bit.
440 - Remove all instances of *ucb* from your path.
441 - Make sure libucb is not in /usr/lib (it should be in /usr/ucblib).
442 - Do not use GNU as or GNU ld, or any of GNU binutils or GNU libc.
443 - Do not use /usr/ucb/cc.
444 - Do not change Configure's default answers, except for the path names.
445 - Do not use -lmalloc.
446 - Do not build on SunOS 4 and expect it to work properly on SunOS 5.
447 - /dev/fd must be mounted if you want set-uid scripts to work.
450 Here are the gcc-related questions and answers from the Solaris 2 FAQ. Note
453 - run fixincludes correctly
454 - don't use GNU as or GNU ld
456 Question 5.7 covers the __builtin_va_alist problem people are always seeing.
457 Question 6.1.3 covers the GNU as and GNU ld issues which are always biting
459 Question 6.9 is for those who are still trying to compile Perl4.
461 The latest Solaris 2 FAQ can be found in the following locations:
462 rtfm.mit.edu:/pub/usenet-by-group/comp.sys.sun.admin
463 ftp.fwi.uva.nl:/pub/solaris
465 Perl5 comes with a script in the top-level directory called "myconfig" which
466 will print a summary of the configuration in your config.sh. My summary for
467 Solaris 2.4 and gcc 2.6.3 follows. I have also built with gcc 2.7.0 and the
468 results are identical. This configuration was generated with Configure's -d
469 option (take all defaults, don't bother prompting me). All tests pass for

502 Subject: Solaris 2 Frequently Asked Questions (FAQ) 1.48
503 Date: 25 Jul 1995 12:20:18 GMT
505 5.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined?
507 You're using gcc without properly installing the gcc fixed
508 include files. Or you ran fixincludes after installing gcc
509 w/o moving the gcc supplied varargs.h and stdarg.h files
510 out of the way and moving them back again later. This often
511 happens when people install gcc from a binary distribution.
512 If there's a tmp directory in gcc's include directory, fixincludes
513 didn't complete. You should have run "just-fixinc" instead.
515 Another possible cause is using ``gcc -I/usr/include.''
517 6.1) Where is the C compiler or where can I get one?
523 Gcc is available from the GNU archives in source and binary
524 form. Look in a directory called sparc-sun-solaris2 for
525 binaries. You need gcc 2.3.3 or later. You should not use
526 GNU as or GNU ld. Make sure you run just-fixinc if you use
527 a binary distribution. Better is to get a binary version and
528 use that to bootstrap gcc from source.
532 When you install gcc, don't make the mistake of installing
533 GNU binutils or GNU libc, they are not as capable as their
534 counterparts you get with Solaris 2.x.
536 6.9) I can't get perl 4.036 to compile or run.
538 Run Configure, and use the solaris_2_0 hints, *don't* use
539 the solaris_2_1 hints and don't use the config.sh you may
540 already have. First you must make sure Configure and make
541 don't find /usr/ucb/cc. (It must use gcc or the native C
542 compiler: /opt/SUNWspro/bin/cc)
544 Some questions need a special answer.
546 Are your system (especially dbm) libraries compiled with gcc? [y] y
548 yes: gcc 2.3.3 or later uses the standard calling
549 conventions, same as Sun's C.
551 Any additional cc flags? [ -traditional -Dvolatile=__volatile__
552 -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__
553 Remove /usr/ucbinclude.
555 Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm
556 -lucb] -lsocket -lnsl -lm
558 Don't include -ldbm, -lmalloc and -lucb.
560 Perl 5 compiled out of the box.
562 7.0) 64-bitness, from Alan Burlison (added by jhi 2000-02-21)
564 You need a machine running Solaris 2.7 or above.
568 1. Solaris 2.7 and above will run in either 32 bit or 64 bit mode,
570 2. You can build 64 bit apps whilst running 32 bit mode and vice-versa.
571 3. 32 bit apps will run under Solaris running in either 32 or 64 bit mode.
572 4. 64 bit apps require Solaris to be running 64 bit mode
573 5. It is possible to select the appropriate 32 or 64 bit version of an
574 app at run-time using isaexec(3).
575 6. You can detect the OS mode using "isainfo -v", e.g.
576 fubar$ isainfo -v # Ultra 30 in 64 bit mode
577 64-bit sparcv9 applications
578 32-bit sparc applications
579 7. To compile 64 bit you need to use the flag "-xarch=v9".
580 getconf(1) will tell you this, e.g.
581 fubar$ getconf -a | grep v9
582 XBS5_LP64_OFF64_CFLAGS: -xarch=v9
583 XBS5_LP64_OFF64_LDFLAGS: -xarch=v9
