293 Here are some notes kindly contributed by Dean Roehrich.
296 Generic notes about building Perl5 on Solaris:
297 - Use /usr/ccs/bin/make.
298 - If you use GNU make, remove its setgid bit.
299 - Remove all instances of *ucb* from your path.
300 - Make sure libucb is not in /usr/lib (it should be in /usr/ucblib).
301 - Do not use GNU as or GNU ld, or any of GNU binutils or GNU libc.
302 - Do not use /usr/ucb/cc.
303 - Do not change Configure's default answers, except for the path names.
304 - Do not use -lmalloc.
305 - Do not build on SunOS 4 and expect it to work properly on SunOS 5.
306 - /dev/fd must be mounted if you want set-uid scripts to work.
309 Here are the gcc-related questions and answers from the Solaris 2 FAQ. Note
312 - run fixincludes correctly
313 - don't use GNU as or GNU ld
315 Question 5.7 covers the __builtin_va_alist problem people are always seeing.
316 Question 6.1.3 covers the GNU as and GNU ld issues which are always biting
318 Question 6.9 is for those who are still trying to compile Perl4.

324 Perl5 comes with a script in the top-level directory called "myconfig" which
325 will print a summary of the configuration in your config.sh. My summary for
326 Solaris 2.4 and gcc 2.6.3 follows. I have also built with gcc 2.7.0 and the
327 results are identical. This configuration was generated with Configure's -d
328 option (take all defaults, don't bother prompting me). All tests pass for

361 Subject: Solaris 2 Frequently Asked Questions (FAQ) 1.48
362 Date: 25 Jul 1995 12:20:18 GMT
364 5.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined?
366 You're using gcc without properly installing the gcc fixed
367 include files. Or you ran fixincludes after installing gcc
368 w/o moving the gcc supplied varargs.h and stdarg.h files
369 out of the way and moving them back again later. This often
370 happens when people install gcc from a binary distribution.
371 If there's a tmp directory in gcc's include directory, fixincludes
372 didn't complete. You should have run "just-fixinc" instead.
374 Another possible cause is using ``gcc -I/usr/include.''
376 6.1) Where is the C compiler or where can I get one?
382 Gcc is available from the GNU archives in source and binary
383 form. Look in a directory called sparc-sun-solaris2 for
384 binaries. You need gcc 2.3.3 or later. You should not use
385 GNU as or GNU ld. Make sure you run just-fixinc if you use
386 a binary distribution. Better is to get a binary version and
387 use that to bootstrap gcc from source.
391 When you install gcc, don't make the mistake of installing
392 GNU binutils or GNU libc, they are not as capable as their
393 counterparts you get with Solaris 2.x.
395 6.9) I can't get perl 4.036 to compile or run.
397 Run Configure, and use the solaris_2_0 hints, *don't* use
398 the solaris_2_1 hints and don't use the config.sh you may
399 already have. First you must make sure Configure and make
400 don't find /usr/ucb/cc. (It must use gcc or the native C
401 compiler: /opt/SUNWspro/bin/cc)
403 Some questions need a special answer.
405 Are your system (especially dbm) libraries compiled with gcc? [y] y
407 yes: gcc 2.3.3 or later uses the standard calling
408 conventions, same as Sun's C.
410 Any additional cc flags? [ -traditional -Dvolatile=__volatile__
411 -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__
412 Remove /usr/ucbinclude.
414 Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm
415 -lucb] -lsocket -lnsl -lm
417 Don't include -ldbm, -lmalloc and -lucb.
