8 # you are using gcc, be sure that you are NOT using GNU as and ld. One
9 # way to do that is to invoke Configure with

27 # GNU CC on the Sparc assumes that doubles are 8 byte aligned.

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

312 5.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined?
314 You're using gcc without properly installing the gcc fixed
315 include files. Or you ran fixincludes after installing gcc
316 w/o moving the gcc supplied varargs.h and stdarg.h files
317 out of the way and moving them back again later. This often
318 happens when people install gcc from a binary distribution.
319 If there's a tmp directory in gcc's include directory, fixincludes
320 didn't complete. You should have run "just-fixinc" instead.
322 Another possible cause is using ``gcc -I/usr/include.''
324 6.1) Where is the C compiler or where can I get one?
330 Gcc is available from the GNU archives in source and binary
331 form. Look in a directory called sparc-sun-solaris2 for
332 binaries. You need gcc 2.3.3 or later. You should not use
333 GNU as or GNU ld. Make sure you run just-fixinc if you use
334 a binary distribution. Better is to get a binary version and
335 use that to bootstrap gcc from source.
339 When you install gcc, don't make the mistake of installing
340 GNU binutils or GNU libc, they are not as capable as their
341 counterparts you get with Solaris 2.x.
343 6.9) I can't get perl 4.036 to compile or run.
345 Run Configure, and use the solaris_2_0 hints, *don't* use
346 the solaris_2_1 hints and don't use the config.sh you may
347 already have. First you must make sure Configure and make
348 don't find /usr/ucb/cc. (It must use gcc or the native C
349 compiler: /opt/SUNWspro/bin/cc)
351 Some questions need a special answer.
353 Are your system (especially dbm) libraries compiled with gcc? [y] y
355 yes: gcc 2.3.3 or later uses the standard calling
356 conventions, same as Sun's C.
358 Any additional cc flags? [ -traditional -Dvolatile=__volatile__
359 -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__
360 Remove /usr/ucbinclude.
362 Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm
363 -lucb] -lsocket -lnsl -lm
365 Don't include -ldbm, -lmalloc and -lucb.
