331 Here are some notes kindly contributed by Dean Roehrich.
334 Generic notes about building Perl5 on Solaris:
335 - Use /usr/ccs/bin/make.
336 - If you use GNU make, remove its setgid bit.
337 - Remove all instances of *ucb* from your path.
338 - Make sure libucb is not in /usr/lib (it should be in /usr/ucblib).
339 - Do not use GNU as or GNU ld, or any of GNU binutils or GNU libc.
340 - Do not use /usr/ucb/cc.
341 - Do not change Configure's default answers, except for the path names.
342 - Do not use -lmalloc.
343 - Do not build on SunOS 4 and expect it to work properly on SunOS 5.
344 - /dev/fd must be mounted if you want set-uid scripts to work.
347 Here are the gcc-related questions and answers from the Solaris 2 FAQ. Note
350 - run fixincludes correctly
351 - don't use GNU as or GNU ld
353 Question 5.7 covers the __builtin_va_alist problem people are always seeing.
354 Question 6.1.3 covers the GNU as and GNU ld issues which are always biting
356 Question 6.9 is for those who are still trying to compile Perl4.
358 The latest Solaris 2 FAQ can be found in the following locations:
359 rtfm.mit.edu:/pub/usenet-by-group/comp.sys.sun.admin
360 ftp.fwi.uva.nl:/pub/solaris
362 Perl5 comes with a script in the top-level directory called "myconfig" which
363 will print a summary of the configuration in your config.sh. My summary for
364 Solaris 2.4 and gcc 2.6.3 follows. I have also built with gcc 2.7.0 and the
365 results are identical. This configuration was generated with Configure's -d
366 option (take all defaults, don't bother prompting me). All tests pass for

399 Subject: Solaris 2 Frequently Asked Questions (FAQ) 1.48
400 Date: 25 Jul 1995 12:20:18 GMT
402 5.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined?
404 You're using gcc without properly installing the gcc fixed
405 include files. Or you ran fixincludes after installing gcc
406 w/o moving the gcc supplied varargs.h and stdarg.h files
407 out of the way and moving them back again later. This often
408 happens when people install gcc from a binary distribution.
409 If there's a tmp directory in gcc's include directory, fixincludes
410 didn't complete. You should have run "just-fixinc" instead.
412 Another possible cause is using ``gcc -I/usr/include.''
414 6.1) Where is the C compiler or where can I get one?
420 Gcc is available from the GNU archives in source and binary
421 form. Look in a directory called sparc-sun-solaris2 for
422 binaries. You need gcc 2.3.3 or later. You should not use
423 GNU as or GNU ld. Make sure you run just-fixinc if you use
424 a binary distribution. Better is to get a binary version and
425 use that to bootstrap gcc from source.
429 When you install gcc, don't make the mistake of installing
430 GNU binutils or GNU libc, they are not as capable as their
431 counterparts you get with Solaris 2.x.
433 6.9) I can't get perl 4.036 to compile or run.
435 Run Configure, and use the solaris_2_0 hints, *don't* use
436 the solaris_2_1 hints and don't use the config.sh you may
437 already have. First you must make sure Configure and make
438 don't find /usr/ucb/cc. (It must use gcc or the native C
439 compiler: /opt/SUNWspro/bin/cc)
441 Some questions need a special answer.
443 Are your system (especially dbm) libraries compiled with gcc? [y] y
445 yes: gcc 2.3.3 or later uses the standard calling
446 conventions, same as Sun's C.
448 Any additional cc flags? [ -traditional -Dvolatile=__volatile__
449 -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__
450 Remove /usr/ucbinclude.
452 Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm
453 -lucb] -lsocket -lnsl -lm
455 Don't include -ldbm, -lmalloc and -lucb.
457 Perl 5 compiled out of the box.
