This file is intended to be a brief introduction to the build |
This file (UPDATING) is intended to be a brief reference to recent |
process and a reference on what to do if something doesn't work. |
changes that might cause problems in the build process, and a guide for |
|
what to do if something doesn't work. |
|
|
|
For a more detailed description of the recommended way to build NetBSD |
|
using build.sh, see the BUILDING file. |
|
|
|
Note that much of the advice in this UPDATING file was written before |
|
build.sh existed. Nevertheless, the advice here may be useful for |
|
working around specific problems with build.sh. |

|
genassym.sh(8) was moved to genassym(1). You need to either build |
|
tools first or install the version of genassym from /usr/bin before |
|
you can build a kernel again. |
|
|
|
20050520: |
|
Because a kernfs bug which xentools relies on was fixed, |
|
xentools up to xentools20-2.0.3nb4 won't work with new kernel. |
|
|
|
20050417: |
|
postinstall(8) was moved from /etc to /usr/sbin and made part |
|
of the "base" set, to make it easier to invoke after an |
|
upgrade. |
|
|
|
20050325: |
|
pcppi(4) was separated in two devices, adding attimer(4). Be sure |
|
to add a config line for an attimer(4) device in your kernel |
|
configuration, or you won't be able to set the pitch of the beep |
|
with wsconsctl. Depending on the default value for the pitch, you |
|
might even not hear any more beep. Also, it is advised to attach both |
|
devices the same way (i.e., both on isa or both on acpi) or the |
|
pcppi(4) device may fail to find the attimer(4) one. |
|
|
|
20050211: |
|
Fixes to tools/Makefile.gnuhost may cause UPDATE=1 builds in |
|
some of the cross tools to fail if they use configure. Some configure's |
|
cache the environment passed in and notice the new environment is |
|
different and abort. Doing a clean in tools/ should be enough to |
|
make a build continue. |
|
|
|
20050109: |
|
Since su is using pam by default now, make sure that you have |
|
/etc/pam.d populated (postinstall will do that automatically |
|
for you). Otherwise su will fail open (i.e. will not require |
|
a password). |
|
|
|
20041229: |
|
Make had a path resolution bug that manifested itself as not |
|
being able to install openpam.3. This bug has been fixed, but |
|
you might need to rebuild make manually first to get through |
|
the build. |
|
|
|
20041201: |
|
Userland programs have been changed to use /dev/bpf instead of |
|
/dev/bpfX. You need to create that device by installing a new |
|
MAKEDEV and running it, or mv /dev/bpf0 /dev/bpf && rm /dev/bpf[0-9]* |
|
|
|
20041006: |
|
|
|
A bug was introduced into /bin/sh (var.c rev 1.35) which causes |
|
variables to not export correctly to subshells in all cases. This |
|
will cause builds to break if that version of /bin/sh is installed |
|
on the system. The proper version of /bin/sh can be verified with: |
|
|
|
ident /bin/sh | grep var |
|
|
|
Any /bin/sh w. version 1.35 will not work and needs to be updated |
|
before attempting a build. |
|
|
|
20041001: |
|
The ipfilter kernel sources moved from sys/netinet to |
|
dist/sys/ipf/netinet. Due to the move some Makefile |
|
dependencies are now dangling requiring a make cleandir |
|
before they work again (kdump, ktruss, rescue, ipf, and |
|
ftp-proxy are the victims). |
|
|
|
20040715: |
|
The rc.d/sendmail script now uses a heuristic to determine |
|
if sendmail should be started at boot time. It checks the |
|
contents of /etc/mailer.conf, /etc/mail/submit.cf, and the |
|
owner and mode of the sendmail binary to see if any changes |
|
to the mail infrastructure have been made. If no changes |
|
are detected, it will start an SMTP listener. |
|
|
|
Setting sendmail=NO in /etc/rc.conf will override this. |
|
|
|
If you are only using sendmail by default and only for |
|
local delivery, it is important that you also update your |
|
sendmail.cf so that the SMTP listener only listens on the |
|
loopback interface. |
|
|
|
20040715: |
|
The method by which athhal-elf.o gets pulled into i386 |
|
kernel builds has been changed again. The latest version |
|
of bsd.files.mk is no longer required. |
|
|
|
20040621: |
|
Due to the recent rototill of tools/compat it's crucial one starts |
|
from a clean objdir under tools/*. |
|
|
|
This is mostly due to generated files (yacc and lex sources) needing |
|
to be generated with new rules from bsd.hostprog.mk. |
|
|
|
The safest course is to rm -rf all objects under tools before building. |
|
|
|
20040516: |
|
The end-user modifiable X11 configuration has been moved |
|
from /usr/X11R6/lib/X11/<dir> to /etc/X11/<dir>. |
|
Ensure that src and xsrc is up to date, and run |
|
"make cleandir" in src/x11 before your next build. |
|
|
|
postinstall currently doesn't migrate the files from |
|
/usr/X11R6/lib/X11/* to /etc/X11/* although it does |
|
detect that this needs to occur, so you'll have to |
|
manually move these files yourself. |
|
|
|
20040426: |
|
Support for the original dynamic sysctl node structure has |
|
been removed in favor of the newer layout. This affects |
|
consumers of the create and delete interface, as well as |
|
the dynamic discovery mechanism. This is believed only to |
|
be the sysctl(8) binary itself, at this point in time, so |
|
the only effect of this should be that a sysctl binary |
|
built from sources dated between 2003/12/04 and 2004/03/24 |
|
will not work on a kernel built from sources dated after |
|
2004/04/25. If you need a new sysctl binary but build.sh |
|
does not work, make sure that your revision of |
|
src/sys/sys/sysctl.h is 1.112 (or later), and then the |
|
do the following: |
|
|
|
cd /usr/src (or wherever your source tree is) |
|
make USETOOLS=no includes |
|
cd lib/libc |
|
make USETOOLS=no dependall install |
|
cd ../../sbin/sysctl |
|
make USETOOLS=no dependall install |
|
|
|
If you are using older sysctl binary, GNU autoconf would fail to |
|
identify your machine architecture, and tries to build binary for |
|
"unknown-unknown-netbsd20F" or something like that. if that happens, |
|
make sure to follow the above steps. |
|
|
|
20040425: |
|
The ffs superblock issues listed below under 20040109 and 20030402 |
|
are now automatically addressed by the /etc/rc.d/fixsb script or by |
|
sysinst when it checks a a filesystem. The manual fsck_ffs -b16 -c4 |
|
invocation mentioned below will continue to work and is now |
|
automated by those scripts. Note that under certain circumstances, |
|
affected filesystems upgraded to a -current kernel first before |
|
upgrading their userland with the fixsb and fsck_ffs fixes may |
|
encounter a 'freeing free inode' panic when writing to the affected |
|
filesystem, so it is a good idea to repair the filesystem as soon as |
|
possible. For more details on the fixsb script, see pr install/25138. |
|
|
|
20040418: |
|
statfs(2) and friends have been replaced with statvfs(2). Before |
|
installing a newly build userland make sure that you are running |
|
a newly built kernel with COMPAT_20 set. In addition your libc |
|
build might not work (undefined SYS_statfs symbol) because make |
|
clean does not know how to remove files it does not know about |
|
anymore. Manually remove all generated .S sources and objects |
|
from the libc build directory. |
|
|
|
20040326: |
|
The method by which athhal-elf.o gets pulled into i386 kernel builds |
|
has been changed. The file is now stored as a uuencoded file in CVS |
|
and the generated Makefile will use the new .uue rules from bsd.file.mk |
|
to build it. |
|
|
|
This means you must have the latest bsd.files.mk installed when |
|
building a kernel without USETOOLS=yes. |
|
|
|
20040318: |
|
A bug in the cgd(4) blowfish code was corrected, without |
|
provision of backwards compatibility, after several public |
|
notices over several months. Users of cgd with blowfish cipher |
|
ONLY must dump their data before updating their kernels, and |
|
recreate cgd's and restore data using the new kernel. See |
|
(recent message to current-users, URL when mail-index has updated) |
|
|
|
20040313: |
|
On acorn32, the opms and qms drivers have been withdrawn, and |
|
the old wsqms driver is now called qms. Kernel config files |
|
will need updating. See the ones in sys/arch/acorn32/conf |
|
for examples. |
|
|
|
20040125: |
|
On acorn32, the beep and sysbeep devices are no longer |
|
needed, and will need to be deleted from kernel configuration |
|
files. |
|
|
|
20040109: |
|
Compatibility for old ffs superblock layouts has been |
|
added, and the restrictive fsck checks have been reenabled |
|
when using those layouts. If you have been using -current |
|
since 20030402, you may find that fsck again signals fatal |
|
superblock mismatches. To repair, make sure you have |
|
an updated fsck_ffs and then you can use fsck_ffs -b 16 -c 4 |
|
to complete the filesystem upgrade. A message has |
|
been added to the kernel which should detect this problem. |
|

|
It's necessary to "make cleandir" to ensure that |
|
the dependencies will be rebuilt correctly. |

|
A sign exension bug was fixed which set all the high bits |
|
of our newly expanded ffs fs_flags. This should only |
|
affect users who installed or upgraded in September of 2003. |
|
A small utility program was posted to tech-kern which |
|
should fix this problem, and a warning message was added |
|
to the kernel which should discover and warn about it. See |
|
