Ben Gras 2fe8fb192f Full switch to clang/ELF. Drop ack. Simplify.
There is important information about booting non-ack images in
docs/UPDATING. ack/aout-format images can't be built any more, and
booting clang/ELF-format ones is a little different. Updating to the
new boot monitor is recommended.

Changes in this commit:

	. drop boot monitor -> allowing dropping ack support
	. facility to copy ELF boot files to /boot so that old boot monitor
	  can still boot fairly easily, see UPDATING
	. no more ack-format libraries -> single-case libraries
	. some cleanup of OBJECT_FMT, COMPILER_TYPE, etc cases
	. drop several ack toolchain commands, but not all support
	  commands (e.g. aal is gone but acksize is not yet).
	. a few libc files moved to netbsd libc dir
	. new /bin/date as minix date used code in libc/
	. test compile fix
	. harmonize includes
	. /usr/lib is no longer special: without ack, /usr/lib plays no
	  kind of special bootstrapping role any more and bootstrapping
	  is done exclusively through packages, so releases depend even
	  less on the state of the machine making them now.
	. rename nbsd_lib* to lib*
	. reduce mtree

Full switch to clang/ELF. ack is no longer supported.
clang is the ELF-generating compiler in the base system, gcc is
available as a package.
To boot ELF-format images, either reinstall your whole system,
thereby getting the netbsd-based boot loader, or use the boot
monitor as documented at
http://wiki.minix3.org/en/UsersGuide/BootMonitor
Single copies of ELF boot files are also stored in /boot on
make hdboot as a boot monitor compatability measure. In short,
to boot the ELF image in /boot using the boot monitor,
do "mb=1" and "kernel=/boot/kernel", then "boot" in the boot
monitor.
Workaround for header file timestamps causing perpetual recompiles:
# find /usr/pkg -name '*.h' | xargs touch
Now that CC is clang instead of ack (cc), the depend files will
be out of date, so to make world, do:
# make cleandepend clean world
20120213
Replace VFS with AVFS
In case you were running AVFS by doing
'BUILDAVFS=yes make clean world', you now have to do a
'make clean cleandepend world' instead of a normal 'make clean world'.
20120202
Rename installboot to installboot_minix.
Do this BEFORE a 'make world':
# rm -f /usr/bin/installboot /usr/sbin/installboot
# make -C boot/installboot clean install
# make -C usr.sbin/installboot clean install
Then 'make clean world' as usual.
20120119:
Follow up to previous entry. The same problem also exists for
the man pages.
Do this BEFORE a 'make world':
# rm /usr/man/man1/rm.1
# cp /usr/man/man1/cp.1 /usr/man/man1/rm.1
Then 'make clean world' as usual.
20120112:
Replace our native rm and rmdir with NetBSD version.
As our native rm is a hard link to cp, simply overwriting rm with
the new version would cause mv, cp, ln, etc to stop working.
Do this BEFORE a 'make world':
# rm /bin/rm
# cp /bin/cp /bin/rm
Then 'make clean world' as usual.
20111222:
This update requires /etc/fstab having the new format.
The latest mkfs.mfs and fsck.mfs must be installed in
/sbin when building a new image, and booting with the new mfs,
and the new system rc script must be installed that invokes the new
fsck driver.
Do this BEFORE a 'make world':
# make clean etcfiles etcforce includes libraries
# make -C commands/mkfs.mfs clean install
# make -C commands/fsck.mfs clean install
Then 'make clean world' as usual.
20111212:
After a successful "make world", issue the following commands:
# cd /dev
# MAKEDEV fbd
20111109:
Switch to NetBSD passwd system.
You have to bootstrap pwd_mkdb:
# make clean includes elf-libraries
# make -C usr.sbin/pwd_mkdb install
Now build world. WARNING: this will blind your system to
/etc/shadow, making current user accounts vanish. Updating the
group file is necessary to add a 'users' group so the new stock
useradd will work.
# make clean world
# cp etc/group /etc/group
The new shadow file is /etc/master.passwd. Add your old user
accounts back with useradd(8), groups with groupadd(8), and
set a root pw with passwd(1) if you want. Use vipw(8) to edit
/etc/master.passwd if you want. See useradd(8) to get started
with the new pw format. Test your new system now by logging in.
Once you're satisfied your new system works, remove the old
adduser, and rely exclusively on the new useradd and
master.passwd.
# rm /usr/bin/adduser
# mv /etc/shadow /etc/shadow.orig
pwdauth is updated so that current binaries (e.g. sshd) will
work with the new pw db.
By default your new users are in the 'users' group. Add yourself
to the 'operator' group if you want to be able to su without
typing in the password.
20111109:
fstab format change. /etc/rc reads both formats for a while.
Please convert your /etc/fstab to the new format though as
the system will assume the new format in the future.
A helper script is in etc/. Example:
# sh etc/newfstab.sh /etc/fstab >newfstab
(Don't redirect to /etc/fstab directly as the shell will
truncate it before it can be read.)
20110928:
Update your /usr/etc/daily and /etc/man.conf if you
want to fully enjoy the manpage fixes.
20110817:
To use the new asynchronous version of VFS do:
# BUILDAVFS=yes make cleandepend world
To switch back to the normal VFS do:
# make cleandepend world
By default the old VFS and PFS are built and included in the boot
image. AVFS is a work in progress and not yet mature. Use at your own
risk.
20110722:
To install the new mkdep:
# cp /usr/bin/mkdep /usr/bin/ackmkdep
# make elf-libraries
# cd usr.bin/mkdep
# touch findcc.d mkdep.d .depend
# make install
20110716:
To install libterminfo and terminfo database, you need
the new stat:
# cd /usr/src/usr.bin/stat
# make clean install
You must create a directory /usr/share/terminfo for terminfo database
to be installed.
# make -C etc install
Then make clean world as normal.
20110708
* VFS and installed MFSes must be in sync before and after this change *
You must update the GNU headers.
# cd /usr/src
# make gnu-includes
You must rebuild both MFS and VFS (including those one in the image).
Either make world or do the following:
# cd /usr/src/servers/mfs
# make install
# cd /usr/src/servers/vfs
# make install
# cd /usr/src/tools
# make hdboot
# shutdown -r now
20110701:
# rm -rf /usr/include /usr/netbsd
# make etcfiles includes cleandepend depend gnu-includes
DOWNGRADING:
Important: this automatically updates your /usr/lib/descr,
something you will have to revert manually if you
want to go back a revision! Previous to this
revision, you do this by:
# cp commands/acd/acd.descr /usr/lib/descr
Repeating the above commands to make sure your /usr/include
is re-acked is probably a good idea too for going back revisions.
This change moves
1. /usr/include to /usr/include.ack
2. /usr/netbsd/include to /usr/include
Reduce compiler cases to only two:
1. ack, a.out, minix headers (moved to /usr/include.ack),
minix libc
2. gcc/clang, elf, netbsd headers (moved to /usr/include),
netbsd libc (moved to /usr/lib)
So this obsoletes the /usr/netbsd hierarchy.
There are no specific UPDATING instructions, but you should know
that starting with this version, gcc/clang use the netbsd libc and
headers system exclusively, and those files are in the standard
locations now. It's the first step to switching completely and
simplifying building.
20110629:
Rebuild m4:
make -C usr.bin/m4 install
20110629:
You must install clang. By default, it is used to build the
elf libraries and some userland utilities.
20110628:
Since buildworld will also build the elf-libraries, you
must follow the process in
http://wiki.minix3.org/en/UsersGuide/ELFSwitch
20110624:
(Next release bumped to MINIX 3.2.0.)
ELF support in the base system. /usr/lib libraries
will be in ELF format once you upgrade.
These were know as 'gcc format', but now more properly refered
to as 'elf format,' as they are shared between gcc and clang.
To start producing ELF, please see:
http://wiki.minix3.org/en/UsersGuide/ELFSwitch
To create the /usr/netbsd hierarchy:
# cd /usr/src
# umount /proc
# make etcfiles
# mount -e -t procfs none /proc
20110225:
Create ddekit include dirs:
mkdir -p /usr/include/ddekit/minix
20100921:
gcc format libraries are created in /usr/lib now,
so throw out /usr/gnu/lib/ if you want to make sure you
don't pick up the old ones.
(with pkgsrc and this, all of /usr/gnu is obsolete now.)
20100914:
mkdir /proc
chmod 555 /proc
20100827:
From now on, the rc scripts, recovery scripts and system.conf in /etc
and /usr/etc are updated automatically by make world. If you want to
change them, do so in the source tree. If you make changes to your
settings in /etc and /usr/etc, merge them into the the source tree
before issuing a make world.
20100805:
mkfs and fsck have been renamed to mkfs.mfs and fsck.mfs, respectively.
Moreover, they have been moved to /sbin, which is by default not in
PATH. Edit your .ashrc (or equivalent) to also include /sbin in PATH.
Also, first issue a 'make commands' before building world.
20100802:
/usr/src/etc/system.conf updated to include ext2 file server: copy it
(or merge it) to /etc/system.conf.
20100719:
If you installed using a 3.1.6 image (or earlier) and haven't updated
the boot monitor since r6246 you need to do so now:
cd /usr/src/boot; make install; sh updateboot.sh
20100714:
mknod /dev/uds c 18 0
chmod 666 /dev/uds
20100713:
/usr/src/etc/rc updated: copy it (or merge it) to /etc/rc.
/usr/src/etc/system.conf updated to include boot sys services: copy
it (or merge it) to /etc/system.conf.
*** WARNING ***: this change breaks binary compatibility with
old images. Use only newly compiled images (make clean world
the first time) or download and install the latest ISO.
20100705:
/usr/src/etc/usr/rc updated: copy it (or merge it) to /usr/etc/rc.
/usr/src/etc/rc updated: copy it (or merge it) to /etc/rc.
Perform some cleanup (optional):
# rm -f /sbin/tty /sbin/log
20100630:
protocol change between service and rs: be sure to compile commands
together with the system image and don't use the new userspace with
an old image (or vice versa); it is recommended to replace
/boot/image_big with the newly compiled image to keep option 1 in the
boot menu working.
20100625:
/etc/mk has been moved to /usr/share/mk. You will need to
create /usr/share/mk manually.
# cp -r /usr/src/share/mk /usr/share/
# cd /usr/src; make -m /usr/share/mk world
20100515:
/usr/src/etc/usr/rc updated: copy it (or merge it) to /usr/etc/rc.
/etc/inet.conf is now line-based; if you have hand-edited this file
before, then make sure that you do not have configurations in there
that span multiple lines.
20100512:
yacc and lex updated
# make includes
# cd commands/yacc
# make depend all install
# cd commands/lex
# LEX=flex make depend all install
20100506:
/usr/src/etc/usr/rc updated: copy it (or merge it) to /usr/etc/rc.
20100410:
/usr/src/etc/usr/rc updated: copy it (or merge it) to /usr/etc/rc.
/usr/src/etc/rc updated: copy it (or merge it) to /etc/rc.
20100408:
/usr/src/etc/usr/rc updated: copy it (or merge it) to /usr/etc/rc.
20100318:
Gas2ack updates: Run 'make install' in commands/i386/gas2ack
20100317:
/usr/src/etc/system.conf updated to ignore default kernel calls: copy
it (or merge it) to /etc/system.conf.
The hello driver (/dev/hello) added to the distribution:
# cd /usr/src/commands/scripts && make clean install
# cd /dev && MAKEDEV hello
20100316:
/usr/man/man9 is required
# mkdir /usr/man/man9
20100308:
Include directory reorganization:
# mv /usr/include/ibm /usr/include/i386
# ln -s /usr/include/i386 /usr/include/machine
Install(1) updates:
# cd commands/simple && make /bin/install
20100303:
Gas2ack updates: Run 'make install' in commands/i386/gas2ack
20100215:
Make(1) has been replaced: Run 'make install' in commands/make
Mkdep updates: Copy commands/scripts/mkdep.sh to /usr/bin/mkdep
Make(1) needs mkfiles: Copy files in etc/mk to /etc/mk
ACK update: Copy commands/i386/acd.descr to /usr/lib/descr
End.a renamed:
-Copy /usr/lib/i86/end.a to /usr/lib/i86/libend.a
-Copy /usr/lib/i386/end.a to /usr/lib/i386/libend.a
-Copy /usr/gnu/lib/end.a to /usr/gnu/lib/libend.a
Asmconv updates: Run 'make install' in commands/i386/asmconv
20091212:
/etc/drivers.conf has been renamed to /etc/system.conf.
user "service" has been added to password file /etc/passwd.
20091006 (r5422):
OSS requires an improved make to be compiled; run "make install"
in /usr/src/commands/make before running "make world".
20070212 (r2751):
mkfs needs more memory to make an image; chmem it or do
# touch mkfs.c ; make /usr/bin/mkfs
in /usr/src/commands/simple.
20070118:
drivers.conf has been updated to include an ACL for mfs. it has
to be installed before rebooting after an update of the mount command.
20061222:
The archictecture-dependent/-independent split needs ARCH=<arch>
in /etc/make.conf, included by some Makefiles and sourced by
some shell scripts. To install it, type 'make install' in
src/etc, or simply copy the file over.
20061222:
Install binaries in the right order because the new readdir
implementation and the new mount program are incompatible
with older kernels and the new kernels require the new mount.
# cd /usr/src
# make includes
# make libraries
# make cmds
# make depend
# cd /usr/src/tools
# make hdboot
# make install
# cd ..
# make install
Installing fails for boot. Reboot the system
# reboot -x 'unset image; boot'
Now install everything
# cd /usr/src
# make install
20060818:
You need flex in your $PATH, which has become part of the base
system. This needs bigger binaries.
If you don't have flex yet, you can compile it first by doing:
# cp /usr/src/etc/binary_sizes* /etc
# binsizes big
# cd /usr/src/commands/flex-2.5.4
# sh build
