224-----
225Generic notes about building Perl5 on Solaris:
226- Use /usr/ccs/bin/make.
227- If you use GNU make, remove its setgid bit.
228- Remove all instances of *ucb* from your path.
229- Make sure libucb is not in /usr/lib (it should be in /usr/ucblib).
230- Do not use GNU as or GNU ld, or any of GNU binutils or GNU libc.
231- Do not use /usr/ucb/cc.
232- Do not change Configure's default answers, except for the path names.
233- Do not use -lmalloc.
234- Do not build on SunOS 4 and expect it to work properly on SunOS 5.
235- /dev/fd must be mounted if you want set-uid scripts to work.
236
237
238Here are the gcc-related questions and answers from the Solaris 2 FAQ. Note
239the themes:
240 - run fixincludes
241 - run fixincludes correctly
242 - don't use GNU as or GNU ld
243
244Question 5.7 covers the __builtin_va_alist problem people are always seeing.
245Question 6.1.3 covers the GNU as and GNU ld issues which are always biting
246people.
247Question 6.9 is for those who are still trying to compile Perl4.
248
249The latest Solaris 2 FAQ can be found in the following locations:
250 rtfm.mit.edu:/pub/usenet-by-group/comp.sys.sun.admin
251 ftp.fwi.uva.nl:/pub/solaris
252
253Perl5 comes with a script in the top-level directory called "myconfig" which
254will print a summary of the configuration in your config.sh. My summary for
255Solaris 2.4 and gcc 2.6.3 follows. I have also built with gcc 2.7.0 and the
256results are identical. This configuration was generated with Configure's -d
257option (take all defaults, don't bother prompting me). All tests pass for
258Perl5.001, patch.1m.

289From: Casper.Dik@Holland.Sun.COM (Casper H.S. Dik - Network Security Engineer)
290Subject: Solaris 2 Frequently Asked Questions (FAQ) 1.48
291Date: 25 Jul 1995 12:20:18 GMT
292
2935.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined?
294
295 You're using gcc without properly installing the gcc fixed
296 include files. Or you ran fixincludes after installing gcc
297 w/o moving the gcc supplied varargs.h and stdarg.h files
298 out of the way and moving them back again later. This often
299 happens when people install gcc from a binary distribution.
300 If there's a tmp directory in gcc's include directory, fixincludes
301 didn't complete. You should have run "just-fixinc" instead.
302
303 Another possible cause is using ``gcc -I/usr/include.''
304
3056.1) Where is the C compiler or where can I get one?
306
307 [...]
308
309 3) Gcc.
310
311 Gcc is available from the GNU archives in source and binary
312 form. Look in a directory called sparc-sun-solaris2 for
313 binaries. You need gcc 2.3.3 or later. You should not use
314 GNU as or GNU ld. Make sure you run just-fixinc if you use
315 a binary distribution. Better is to get a binary version and
316 use that to bootstrap gcc from source.
317
318 [...]
319
320 When you install gcc, don't make the mistake of installing
321 GNU binutils or GNU libc, they are not as capable as their
322 counterparts you get with Solaris 2.x.
323
3246.9) I can't get perl 4.036 to compile or run.
325
326 Run Configure, and use the solaris_2_0 hints, *don't* use
327 the solaris_2_1 hints and don't use the config.sh you may
328 already have. First you must make sure Configure and make
329 don't find /usr/ucb/cc. (It must use gcc or the native C
330 compiler: /opt/SUNWspro/bin/cc)
331
332 Some questions need a special answer.
333
334 Are your system (especially dbm) libraries compiled with gcc? [y] y
335
336 yes: gcc 2.3.3 or later uses the standard calling
337 conventions, same as Sun's C.
338
339 Any additional cc flags? [ -traditional -Dvolatile=__volatile__
340 -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__
341 Remove /usr/ucbinclude.
342
343 Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm
344 -lucb] -lsocket -lnsl -lm
345
346 Don't include -ldbm, -lmalloc and -lucb.
347
348 Perl 5 compiled out of the box.
