276
277-----
278Generic notes about building Perl5 on Solaris:
279- Use /usr/ccs/bin/make.
280- If you use GNU make, remove its setgid bit.
281- Remove all instances of *ucb* from your path.
282- Make sure libucb is not in /usr/lib (it should be in /usr/ucblib).
283- Do not use GNU as or GNU ld, or any of GNU binutils or GNU libc.
284- Do not use /usr/ucb/cc.
285- Do not change Configure's default answers, except for the path names.
286- Do not use -lmalloc.
287- Do not build on SunOS 4 and expect it to work properly on SunOS 5.
288- /dev/fd must be mounted if you want set-uid scripts to work.
289
290
291Here are the gcc-related questions and answers from the Solaris 2 FAQ. Note
292the themes:
293 - run fixincludes
294 - run fixincludes correctly
295 - don't use GNU as or GNU ld
296
297Question 5.7 covers the __builtin_va_alist problem people are always seeing.
298Question 6.1.3 covers the GNU as and GNU ld issues which are always biting
299people.
300Question 6.9 is for those who are still trying to compile Perl4.
301
302The latest Solaris 2 FAQ can be found in the following locations:
303 rtfm.mit.edu:/pub/usenet-by-group/comp.sys.sun.admin
304 ftp.fwi.uva.nl:/pub/solaris
305
306Perl5 comes with a script in the top-level directory called "myconfig" which
307will print a summary of the configuration in your config.sh. My summary for
308Solaris 2.4 and gcc 2.6.3 follows. I have also built with gcc 2.7.0 and the
309results are identical. This configuration was generated with Configure's -d
310option (take all defaults, don't bother prompting me). All tests pass for
311Perl5.001, patch.1m.

342From: Casper.Dik@Holland.Sun.COM (Casper H.S. Dik - Network Security Engineer)
343Subject: Solaris 2 Frequently Asked Questions (FAQ) 1.48
344Date: 25 Jul 1995 12:20:18 GMT
345
3465.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined?
347
348 You're using gcc without properly installing the gcc fixed
349 include files. Or you ran fixincludes after installing gcc
350 w/o moving the gcc supplied varargs.h and stdarg.h files
351 out of the way and moving them back again later. This often
352 happens when people install gcc from a binary distribution.
353 If there's a tmp directory in gcc's include directory, fixincludes
354 didn't complete. You should have run "just-fixinc" instead.
355
356 Another possible cause is using ``gcc -I/usr/include.''
357
3586.1) Where is the C compiler or where can I get one?
359
360 [...]
361
362 3) Gcc.
363
364 Gcc is available from the GNU archives in source and binary
365 form. Look in a directory called sparc-sun-solaris2 for
366 binaries. You need gcc 2.3.3 or later. You should not use
367 GNU as or GNU ld. Make sure you run just-fixinc if you use
368 a binary distribution. Better is to get a binary version and
369 use that to bootstrap gcc from source.
370
371 [...]
372
373 When you install gcc, don't make the mistake of installing
374 GNU binutils or GNU libc, they are not as capable as their
375 counterparts you get with Solaris 2.x.
376
3776.9) I can't get perl 4.036 to compile or run.
378
379 Run Configure, and use the solaris_2_0 hints, *don't* use
380 the solaris_2_1 hints and don't use the config.sh you may
381 already have. First you must make sure Configure and make
382 don't find /usr/ucb/cc. (It must use gcc or the native C
383 compiler: /opt/SUNWspro/bin/cc)
384
385 Some questions need a special answer.
386
387 Are your system (especially dbm) libraries compiled with gcc? [y] y
388
389 yes: gcc 2.3.3 or later uses the standard calling
390 conventions, same as Sun's C.
391
392 Any additional cc flags? [ -traditional -Dvolatile=__volatile__
393 -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__
394 Remove /usr/ucbinclude.
395
396 Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm
397 -lucb] -lsocket -lnsl -lm
398
399 Don't include -ldbm, -lmalloc and -lucb.
400
401 Perl 5 compiled out of the box.
