------
-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.

-From: Casper.Dik@Holland.Sun.COM (Casper H.S. Dik - Network Security Engineer)
-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.
-
-7.0) 64-bitness, from Alan Burlison (added by jhi 2000-02-21)
-
- You need a machine running Solaris 2.7 or above.
-
- Here's some rules:
-
- 1. Solaris 2.7 and above will run in either 32 bit or 64 bit mode,
- via a reboot.
- 2. You can build 64 bit apps whilst running 32 bit mode and vice-versa.
- 3. 32 bit apps will run under Solaris running in either 32 or 64 bit mode.
- 4. 64 bit apps require Solaris to be running 64 bit mode
- 5. It is possible to select the appropriate 32 or 64 bit version of an
- app at run-time using isaexec(3).
- 6. You can detect the OS mode using "isainfo -v", e.g.
- fubar$ isainfo -v # Ultra 30 in 64 bit mode
- 64-bit sparcv9 applications
- 32-bit sparc applications
- 7. To compile 64 bit you need to use the flag "-xarch=v9".
- getconf(1) will tell you this, e.g.
- fubar$ getconf -a | grep v9
- XBS5_LP64_OFF64_CFLAGS: -xarch=v9
- XBS5_LP64_OFF64_LDFLAGS: -xarch=v9
