+
+-----
+Generic notes about building Perl5 on Solaris:
+- Use /usr/ccs/bin/make.
+- If you use GNU make, remove its setgid bit.
+- Remove all instances of *ucb* from your path.
+- Make sure libucb is not in /usr/lib (it should be in /usr/ucblib).
+- Do not use GNU as or GNU ld, or any of GNU binutils or GNU libc.
+- Do not use /usr/ucb/cc.
+- Do not change Configure's default answers, except for the path names.
+- Do not use -lmalloc.
+- Do not build on SunOS 4 and expect it to work properly on SunOS 5.
+- /dev/fd must be mounted if you want set-uid scripts to work.
+
+
+Here are the gcc-related questions and answers from the Solaris 2 FAQ. Note
+the themes:
+ - run fixincludes
+ - run fixincludes correctly
+ - don't use GNU as or GNU ld
+
+Question 5.7 covers the __builtin_va_alist problem people are always seeing.
+Question 6.1.3 covers the GNU as and GNU ld issues which are always biting
+people.
+Question 6.9 is for those who are still trying to compile Perl4.
+
+The latest Solaris 2 FAQ can be found in the following locations:
+ rtfm.mit.edu:/pub/usenet-by-group/comp.sys.sun.admin
+ ftp.fwi.uva.nl:/pub/solaris
+
+Perl5 comes with a script in the top-level directory called "myconfig" which
+will print a summary of the configuration in your config.sh. My summary for
+Solaris 2.4 and gcc 2.6.3 follows. I have also built with gcc 2.7.0 and the
+results are identical. This configuration was generated with Configure's -d
+option (take all defaults, don't bother prompting me). All tests pass for
+Perl5.001, patch.1m.
+
+Summary of my perl5 (patchlevel 1) configuration:
+ Platform:
+ osname=solaris, osver=2.4, archname=sun4-solaris
+ uname='sunos poplar 5.4 generic_101945-27 sun4d sparc '
+ hint=recommended

+Subject: Solaris 2 Frequently Asked Questions (FAQ) 1.48
+Date: 25 Jul 1995 12:20:18 GMT
+
+5.7) Why do I get __builtin_va_alist or __builtin_va_arg_incr undefined?
+
+ You're using gcc without properly installing the gcc fixed
+ include files. Or you ran fixincludes after installing gcc
+ w/o moving the gcc supplied varargs.h and stdarg.h files
+ out of the way and moving them back again later. This often
+ happens when people install gcc from a binary distribution.
+ If there's a tmp directory in gcc's include directory, fixincludes
+ didn't complete. You should have run "just-fixinc" instead.
+
+ Another possible cause is using ``gcc -I/usr/include.''
+
+6.1) Where is the C compiler or where can I get one?
+
+ [...]
+
+ 3) Gcc.
+
+ Gcc is available from the GNU archives in source and binary
+ form. Look in a directory called sparc-sun-solaris2 for
+ binaries. You need gcc 2.3.3 or later. You should not use
+ GNU as or GNU ld. Make sure you run just-fixinc if you use
+ a binary distribution. Better is to get a binary version and
+ use that to bootstrap gcc from source.
+
+ [...]
+
+ When you install gcc, don't make the mistake of installing
+ GNU binutils or GNU libc, they are not as capable as their
+ counterparts you get with Solaris 2.x.
+
+6.9) I can't get perl 4.036 to compile or run.
+
+ Run Configure, and use the solaris_2_0 hints, *don't* use
+ the solaris_2_1 hints and don't use the config.sh you may
+ already have. First you must make sure Configure and make
+ don't find /usr/ucb/cc. (It must use gcc or the native C
+ compiler: /opt/SUNWspro/bin/cc)
+
+ Some questions need a special answer.
+
+ Are your system (especially dbm) libraries compiled with gcc? [y] y
+
+ yes: gcc 2.3.3 or later uses the standard calling
+ conventions, same as Sun's C.
+
+ Any additional cc flags? [ -traditional -Dvolatile=__volatile__
+ -I/usr/ucbinclude] -traditional -Dvolatile=__volatile__
+ Remove /usr/ucbinclude.
+
+ Any additional libraries? [-lsocket -lnsl -ldbm -lmalloc -lm
+ -lucb] -lsocket -lnsl -lm
+
+ Don't include -ldbm, -lmalloc and -lucb.
+
+ Perl 5 compiled out of the box.
