208-----
209Generic notes about building Perl5 on Solaris:
210- Use /usr/ccs/bin/make.
211- If you use GNU make, remove its setgid bit.
212- Remove all instances of *ucb* from your path.
213- Make sure libucb is not in /usr/lib (it should be in /usr/ucblib).
214- Do not use GNU as or GNU ld, or any of GNU binutils or GNU libc.
215- Do not use /usr/ucb/cc.
216- Do not change Configure's default answers, except for the path names.
217- Do not use -lmalloc.
218- Do not build on SunOS 4 and expect it to work properly on SunOS 5.
219- /dev/fd must be mounted if you want set-uid scripts to work.
220
221
222Here are the gcc-related questions and answers from the Solaris 2 FAQ. Note
223the themes:
224 - run fixincludes
225 - run fixincludes correctly
226 - don't use GNU as or GNU ld
227
228Question 5.7 covers the __builtin_va_alist problem people are always seeing.
229Question 6.1.3 covers the GNU as and GNU ld issues which are always biting
230people.
231Question 6.9 is for those who are still trying to compile Perl4.
232
233The latest Solaris 2 FAQ can be found in the following locations:
234 rtfm.mit.edu:/pub/usenet-by-group/comp.sys.sun.admin
235 ftp.fwi.uva.nl:/pub/solaris
236
237Perl5 comes with a script in the top-level directory called "myconfig" which
238will print a summary of the configuration in your config.sh. My summary for
239Solaris 2.4 and gcc 2.6.3 follows. I have also built with gcc 2.7.0 and the
240results are identical. This configuration was generated with Configure's -d
241option (take all defaults, don't bother prompting me). All tests pass for
242Perl5.001, patch.1m.

273From: Casper.Dik@Holland.Sun.COM (Casper H.S. Dik - Network Security Engineer)
274Subject: Solaris 2 Frequently Asked Questions (FAQ) 1.48
275Date: 25 Jul 1995 12:20:18 GMT
276
2775.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined?
278
279 You're using gcc without properly installing the gcc fixed
280 include files. Or you ran fixincludes after installing gcc
281 w/o moving the gcc supplied varargs.h and stdarg.h files
282 out of the way and moving them back again later. This often
283 happens when people install gcc from a binary distribution.
284 If there's a tmp directory in gcc's include directory, fixincludes
285 didn't complete. You should have run "just-fixinc" instead.
286
287 Another possible cause is using ``gcc -I/usr/include.''
288
2896.1) Where is the C compiler or where can I get one?
290
291 [...]
292
293 3) Gcc.
294
295 Gcc is available from the GNU archives in source and binary
296 form. Look in a directory called sparc-sun-solaris2 for
297 binaries. You need gcc 2.3.3 or later. You should not use
298 GNU as or GNU ld. Make sure you run just-fixinc if you use
299 a binary distribution. Better is to get a binary version and
300 use that to bootstrap gcc from source.
301
302 [...]
303
304 When you install gcc, don't make the mistake of installing
305 GNU binutils or GNU libc, they are not as capable as their
306 counterparts you get with Solaris 2.x.
307
3086.9) I can't get perl 4.036 to compile or run.
309
310 Run Configure, and use the solaris_2_0 hints, *don't* use
311 the solaris_2_1 hints and don't use the config.sh you may
312 already have. First you must make sure Configure and make
313 don't find /usr/ucb/cc. (It must use gcc or the native C
314 compiler: /opt/SUNWspro/bin/cc)
315
316 Some questions need a special answer.
317
318 Are your system (especially dbm) libraries compiled with gcc? [y] y
319
320 yes: gcc 2.3.3 or later uses the standard calling
321 conventions, same as Sun's C.
322
323 Any additional cc flags? [ -traditional -Dvolatile=__volatile__
324 -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__
325 Remove /usr/ucbinclude.
326
327 Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm
328 -lucb] -lsocket -lnsl -lm
329
330 Don't include -ldbm, -lmalloc and -lucb.
331
332 Perl 5 compiled out of the box.
