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

19 # Avoid all libraries in /usr/ucblib.

25 # -lmalloc can cause a problem with GNU CC & Solaris. Specifically,
26 # libmalloc.a may allocate memory that is only 4 byte aligned, but
27 # GNU CC on the Sparc assumes that doubles are 8 byte aligned.

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

311 5.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined?
313 You're using gcc without properly installing the gcc fixed
314 include files. Or you ran fixincludes after installing gcc
315 w/o moving the gcc supplied varargs.h and stdarg.h files
316 out of the way and moving them back again later. This often
317 happens when people install gcc from a binary distribution.
318 If there's a tmp directory in gcc's include directory, fixincludes
319 didn't complete. You should have run "just-fixinc" instead.
321 Another possible cause is using ``gcc -I/usr/include.''
323 6.1) Where is the C compiler or where can I get one?
329 Gcc is available from the GNU archives in source and binary
330 form. Look in a directory called sparc-sun-solaris2 for
331 binaries. You need gcc 2.3.3 or later. You should not use
332 GNU as or GNU ld. Make sure you run just-fixinc if you use
333 a binary distribution. Better is to get a binary version and
334 use that to bootstrap gcc from source.
338 When you install gcc, don't make the mistake of installing
339 GNU binutils or GNU libc, they are not as capable as their
340 counterparts you get with Solaris 2.x.
342 6.9) I can't get perl 4.036 to compile or run.
344 Run Configure, and use the solaris_2_0 hints, *don't* use
345 the solaris_2_1 hints and don't use the config.sh you may
346 already have. First you must make sure Configure and make
347 don't find /usr/ucb/cc. (It must use gcc or the native C
348 compiler: /opt/SUNWspro/bin/cc)
350 Some questions need a special answer.
352 Are your system (especially dbm) libraries compiled with gcc? [y] y
354 yes: gcc 2.3.3 or later uses the standard calling
355 conventions, same as Sun's C.
357 Any additional cc flags? [ -traditional -Dvolatile=__volatile__
358 -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__
359 Remove /usr/ucbinclude.
361 Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm
362 -lucb] -lsocket -lnsl -lm
364 Don't include -ldbm, -lmalloc and -lucb.
