221
222-----
223Generic notes about building Perl5 on Solaris:
224- Use /usr/ccs/bin/make.
225- If you use GNU make, remove its setgid bit.
226- Remove all instances of *ucb* from your path.
227- Make sure libucb is not in /usr/lib (it should be in /usr/ucblib).
228- Do not use GNU as or GNU ld, or any of GNU binutils or GNU libc.
229- Do not use /usr/ucb/cc.
230- Do not change Configure's default answers, except for the path names.
231- Do not use -lmalloc.
232- Do not build on SunOS 4 and expect it to work properly on SunOS 5.
233- /dev/fd must be mounted if you want set-uid scripts to work.
234
235
236Here are the gcc-related questions and answers from the Solaris 2 FAQ. Note
237the themes:
238 - run fixincludes
239 - run fixincludes correctly
240 - don't use GNU as or GNU ld
241
242Question 5.7 covers the __builtin_va_alist problem people are always seeing.
243Question 6.1.3 covers the GNU as and GNU ld issues which are always biting
244people.
245Question 6.9 is for those who are still trying to compile Perl4.
246
247The latest Solaris 2 FAQ can be found in the following locations:

250
251Perl5 comes with a script in the top-level directory called "myconfig" which
252will print a summary of the configuration in your config.sh. My summary for
253Solaris 2.4 and gcc 2.6.3 follows. I have also built with gcc 2.7.0 and the
254results are identical. This configuration was generated with Configure's -d
255option (take all defaults, don't bother prompting me). All tests pass for
256Perl5.001, patch.1m.

287From: Casper.Dik@Holland.Sun.COM (Casper H.S. Dik - Network Security Engineer)
288Subject: Solaris 2 Frequently Asked Questions (FAQ) 1.48
289Date: 25 Jul 1995 12:20:18 GMT
290
2915.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined?
292
293 You're using gcc without properly installing the gcc fixed
294 include files. Or you ran fixincludes after installing gcc
295 w/o moving the gcc supplied varargs.h and stdarg.h files
296 out of the way and moving them back again later. This often
297 happens when people install gcc from a binary distribution.
298 If there's a tmp directory in gcc's include directory, fixincludes
299 didn't complete. You should have run "just-fixinc" instead.
300
301 Another possible cause is using ``gcc -I/usr/include.''
302
3036.1) Where is the C compiler or where can I get one?
304
305 [...]
306
307 3) Gcc.
308
309 Gcc is available from the GNU archives in source and binary
310 form. Look in a directory called sparc-sun-solaris2 for
311 binaries. You need gcc 2.3.3 or later. You should not use
312 GNU as or GNU ld. Make sure you run just-fixinc if you use
313 a binary distribution. Better is to get a binary version and
314 use that to bootstrap gcc from source.
315
316 [...]
317
318 When you install gcc, don't make the mistake of installing
319 GNU binutils or GNU libc, they are not as capable as their
320 counterparts you get with Solaris 2.x.
321
3226.9) I can't get perl 4.036 to compile or run.
323
324 Run Configure, and use the solaris_2_0 hints, *don't* use
325 the solaris_2_1 hints and don't use the config.sh you may
326 already have. First you must make sure Configure and make
327 don't find /usr/ucb/cc. (It must use gcc or the native C
328 compiler: /opt/SUNWspro/bin/cc)
329
330 Some questions need a special answer.
331
332 Are your system (especially dbm) libraries compiled with gcc? [y] y
333
334 yes: gcc 2.3.3 or later uses the standard calling
335 conventions, same as Sun's C.
336
337 Any additional cc flags? [ -traditional -Dvolatile=__volatile__
338 -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__
339 Remove /usr/ucbinclude.
340
341 Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm
342 -lucb] -lsocket -lnsl -lm
343
344 Don't include -ldbm, -lmalloc and -lucb.
345
346 Perl 5 compiled out of the box.
