378 Here are some notes kindly contributed by Dean Roehrich.
381 Generic notes about building Perl5 on Solaris:
382 - Use /usr/ccs/bin/make.
383 - If you use GNU make, remove its setgid bit.
384 - Remove all instances of *ucb* from your path.
385 - Make sure libucb is not in /usr/lib (it should be in /usr/ucblib).
386 - Do not use GNU as or GNU ld, or any of GNU binutils or GNU libc.
387 - Do not use /usr/ucb/cc.
388 - Do not change Configure's default answers, except for the path names.
389 - Do not use -lmalloc.
390 - Do not build on SunOS 4 and expect it to work properly on SunOS 5.
391 - /dev/fd must be mounted if you want set-uid scripts to work.
394 Here are the gcc-related questions and answers from the Solaris 2 FAQ. Note
397 - run fixincludes correctly
398 - don't use GNU as or GNU ld
400 Question 5.7 covers the __builtin_va_alist problem people are always seeing.
401 Question 6.1.3 covers the GNU as and GNU ld issues which are always biting
403 Question 6.9 is for those who are still trying to compile Perl4.
405 The latest Solaris 2 FAQ can be found in the following locations:
406 rtfm.mit.edu:/pub/usenet-by-group/comp.sys.sun.admin
407 ftp.fwi.uva.nl:/pub/solaris
409 Perl5 comes with a script in the top-level directory called "myconfig" which
410 will print a summary of the configuration in your config.sh. My summary for
411 Solaris 2.4 and gcc 2.6.3 follows. I have also built with gcc 2.7.0 and the
412 results are identical. This configuration was generated with Configure's -d
413 option (take all defaults, don't bother prompting me). All tests pass for

446 Subject: Solaris 2 Frequently Asked Questions (FAQ) 1.48
447 Date: 25 Jul 1995 12:20:18 GMT
449 5.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined?
451 You're using gcc without properly installing the gcc fixed
452 include files. Or you ran fixincludes after installing gcc
453 w/o moving the gcc supplied varargs.h and stdarg.h files
454 out of the way and moving them back again later. This often
455 happens when people install gcc from a binary distribution.
456 If there's a tmp directory in gcc's include directory, fixincludes
457 didn't complete. You should have run "just-fixinc" instead.
459 Another possible cause is using ``gcc -I/usr/include.''
461 6.1) Where is the C compiler or where can I get one?
467 Gcc is available from the GNU archives in source and binary
468 form. Look in a directory called sparc-sun-solaris2 for
469 binaries. You need gcc 2.3.3 or later. You should not use
470 GNU as or GNU ld. Make sure you run just-fixinc if you use
471 a binary distribution. Better is to get a binary version and
472 use that to bootstrap gcc from source.
476 When you install gcc, don't make the mistake of installing
477 GNU binutils or GNU libc, they are not as capable as their
478 counterparts you get with Solaris 2.x.
480 6.9) I can't get perl 4.036 to compile or run.
482 Run Configure, and use the solaris_2_0 hints, *don't* use
483 the solaris_2_1 hints and don't use the config.sh you may
484 already have. First you must make sure Configure and make
485 don't find /usr/ucb/cc. (It must use gcc or the native C
486 compiler: /opt/SUNWspro/bin/cc)
488 Some questions need a special answer.
490 Are your system (especially dbm) libraries compiled with gcc? [y] y
492 yes: gcc 2.3.3 or later uses the standard calling
493 conventions, same as Sun's C.
495 Any additional cc flags? [ -traditional -Dvolatile=__volatile__
496 -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__
497 Remove /usr/ucbinclude.
499 Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm
500 -lucb] -lsocket -lnsl -lm
502 Don't include -ldbm, -lmalloc and -lucb.
504 Perl 5 compiled out of the box.
