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

258 ftp.fwi.uva.nl:/pub/solaris
260 Perl5 comes with a script in the top-level directory called "myconfig" which
261 will print a summary of the configuration in your config.sh. My summary for
262 Solaris 2.4 and gcc 2.6.3 follows. I have also built with gcc 2.7.0 and the
263 results are identical. This configuration was generated with Configure's -d
264 option (take all defaults, don't bother prompting me). All tests pass for

300 5.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined?
302 You're using gcc without properly installing the gcc fixed
303 include files. Or you ran fixincludes after installing gcc
304 w/o moving the gcc supplied varargs.h and stdarg.h files
305 out of the way and moving them back again later. This often
306 happens when people install gcc from a binary distribution.
307 If there's a tmp directory in gcc's include directory, fixincludes
308 didn't complete. You should have run "just-fixinc" instead.
310 Another possible cause is using ``gcc -I/usr/include.''
312 6.1) Where is the C compiler or where can I get one?
318 Gcc is available from the GNU archives in source and binary
319 form. Look in a directory called sparc-sun-solaris2 for
320 binaries. You need gcc 2.3.3 or later. You should not use
321 GNU as or GNU ld. Make sure you run just-fixinc if you use
322 a binary distribution. Better is to get a binary version and
323 use that to bootstrap gcc from source.
327 When you install gcc, don't make the mistake of installing
328 GNU binutils or GNU libc, they are not as capable as their
329 counterparts you get with Solaris 2.x.
331 6.9) I can't get perl 4.036 to compile or run.
333 Run Configure, and use the solaris_2_0 hints, *don't* use
334 the solaris_2_1 hints and don't use the config.sh you may
335 already have. First you must make sure Configure and make
336 don't find /usr/ucb/cc. (It must use gcc or the native C
337 compiler: /opt/SUNWspro/bin/cc)
339 Some questions need a special answer.
341 Are your system (especially dbm) libraries compiled with gcc? [y] y
343 yes: gcc 2.3.3 or later uses the standard calling
344 conventions, same as Sun's C.
346 Any additional cc flags? [ -traditional -Dvolatile=__volatile__
347 -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__
348 Remove /usr/ucbinclude.
350 Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm
351 -lucb] -lsocket -lnsl -lm
353 Don't include -ldbm, -lmalloc and -lucb.
