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

336 Date: 25 Jul 1995 12:20:18 GMT
338 5.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined?
340 You're using gcc without properly installing the gcc fixed
341 include files. Or you ran fixincludes after installing gcc
342 w/o moving the gcc supplied varargs.h and stdarg.h files
343 out of the way and moving them back again later. This often
344 happens when people install gcc from a binary distribution.
345 If there's a tmp directory in gcc's include directory, fixincludes
346 didn't complete. You should have run "just-fixinc" instead.
348 Another possible cause is using ``gcc -I/usr/include.''
350 6.1) Where is the C compiler or where can I get one?
356 Gcc is available from the GNU archives in source and binary
357 form. Look in a directory called sparc-sun-solaris2 for
358 binaries. You need gcc 2.3.3 or later. You should not use
359 GNU as or GNU ld. Make sure you run just-fixinc if you use
360 a binary distribution. Better is to get a binary version and
361 use that to bootstrap gcc from source.
365 When you install gcc, don't make the mistake of installing
366 GNU binutils or GNU libc, they are not as capable as their
367 counterparts you get with Solaris 2.x.
369 6.9) I can't get perl 4.036 to compile or run.
371 Run Configure, and use the solaris_2_0 hints, *don't* use
372 the solaris_2_1 hints and don't use the config.sh you may
373 already have. First you must make sure Configure and make
374 don't find /usr/ucb/cc. (It must use gcc or the native C
375 compiler: /opt/SUNWspro/bin/cc)
377 Some questions need a special answer.
379 Are your system (especially dbm) libraries compiled with gcc? [y] y
381 yes: gcc 2.3.3 or later uses the standard calling
382 conventions, same as Sun's C.
384 Any additional cc flags? [ -traditional -Dvolatile=__volatile__
385 -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__
386 Remove /usr/ucbinclude.
388 Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm
389 -lucb] -lsocket -lnsl -lm
391 Don't include -ldbm, -lmalloc and -lucb.
