265Here are some notes kindly contributed by Dean Roehrich.
266
267-----
268Generic notes about building Perl5 on Solaris:
269- Use /usr/ccs/bin/make.
270- If you use GNU make, remove its setgid bit.
271- Remove all instances of *ucb* from your path.
272- Make sure libucb is not in /usr/lib (it should be in /usr/ucblib).
273- Do not use GNU as or GNU ld, or any of GNU binutils or GNU libc.
274- Do not use /usr/ucb/cc.
275- Do not change Configure's default answers, except for the path names.
276- Do not use -lmalloc.
277- Do not build on SunOS 4 and expect it to work properly on SunOS 5.
278- /dev/fd must be mounted if you want set-uid scripts to work.
279
280
281Here are the gcc-related questions and answers from the Solaris 2 FAQ. Note
282the themes:
283 - run fixincludes
284 - run fixincludes correctly
285 - don't use GNU as or GNU ld
286
287Question 5.7 covers the __builtin_va_alist problem people are always seeing.
288Question 6.1.3 covers the GNU as and GNU ld issues which are always biting
289people.
290Question 6.9 is for those who are still trying to compile Perl4.
291
292The latest Solaris 2 FAQ can be found in the following locations:
293 rtfm.mit.edu:/pub/usenet-by-group/comp.sys.sun.admin
294 ftp.fwi.uva.nl:/pub/solaris
295
296Perl5 comes with a script in the top-level directory called "myconfig" which
297will print a summary of the configuration in your config.sh. My summary for
298Solaris 2.4 and gcc 2.6.3 follows. I have also built with gcc 2.7.0 and the
299results are identical. This configuration was generated with Configure's -d
300option (take all defaults, don't bother prompting me). All tests pass for
301Perl5.001, patch.1m.

332From: Casper.Dik@Holland.Sun.COM (Casper H.S. Dik - Network Security Engineer)
333Subject: Solaris 2 Frequently Asked Questions (FAQ) 1.48
334Date: 25 Jul 1995 12:20:18 GMT
335
3365.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined?
337
338 You're using gcc without properly installing the gcc fixed
339 include files. Or you ran fixincludes after installing gcc
340 w/o moving the gcc supplied varargs.h and stdarg.h files
341 out of the way and moving them back again later. This often
342 happens when people install gcc from a binary distribution.
343 If there's a tmp directory in gcc's include directory, fixincludes
344 didn't complete. You should have run "just-fixinc" instead.
345
346 Another possible cause is using ``gcc -I/usr/include.''
347
3486.1) Where is the C compiler or where can I get one?
349
350 [...]
351
352 3) Gcc.
353
354 Gcc is available from the GNU archives in source and binary
355 form. Look in a directory called sparc-sun-solaris2 for
356 binaries. You need gcc 2.3.3 or later. You should not use
357 GNU as or GNU ld. Make sure you run just-fixinc if you use
358 a binary distribution. Better is to get a binary version and
359 use that to bootstrap gcc from source.
360
361 [...]
362
363 When you install gcc, don't make the mistake of installing
364 GNU binutils or GNU libc, they are not as capable as their
365 counterparts you get with Solaris 2.x.
366
3676.9) I can't get perl 4.036 to compile or run.
368
369 Run Configure, and use the solaris_2_0 hints, *don't* use
370 the solaris_2_1 hints and don't use the config.sh you may
371 already have. First you must make sure Configure and make
372 don't find /usr/ucb/cc. (It must use gcc or the native C
373 compiler: /opt/SUNWspro/bin/cc)
374
375 Some questions need a special answer.
376
377 Are your system (especially dbm) libraries compiled with gcc? [y] y
378
379 yes: gcc 2.3.3 or later uses the standard calling
380 conventions, same as Sun's C.
381
382 Any additional cc flags? [ -traditional -Dvolatile=__volatile__
383 -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__
384 Remove /usr/ucbinclude.
385
386 Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm
387 -lucb] -lsocket -lnsl -lm
388
389 Don't include -ldbm, -lmalloc and -lucb.
390
391 Perl 5 compiled out of the box.
