1.182 ! tsutsui 1: $NetBSD: UPDATING,v 1.181 2008/12/06 20:23:38 cube Exp $
1.1 abs 2:
1.123 jmc 3: This file (UPDATING) is intended to be a brief reference to recent
4: changes that might cause problems in the build process, and a guide for
5: what to do if something doesn't work.
1.1 abs 6:
1.123 jmc 7: For a more detailed description of the recommended way to build NetBSD
8: using build.sh, see the BUILDING file.
9:
10: Note that much of the advice in this UPDATING file was written before
11: build.sh existed. Nevertheless, the advice here may be useful for
12: working around specific problems with build.sh.

1.181 cube 19: 20081205:
20: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
21: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
22: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 23:
1.179 tsutsui 24: 20081122:
1.182 ! tsutsui 25: On i386, various kernel options(4) in GENERIC including
1.180 wiz 26: file systems have been disabled and moved into kernel modules.
27: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 28: following files as well as a new GENERIC kernel:
29:
30: - build and install kernel modules from src/sys/modules
31:
32: - install the latest bootloader, which will load a module
1.180 wiz 33: for the file system from which the kernel is loaded automatically
1.179 tsutsui 34:
1.180 wiz 35: If you have to load your kernel from a file system which is not of
36: the same type as the root file system, you have to load the necessary
37: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 38:
1.178 lukem 39: 20080827:
40: If you built and installed a libc from sources between
41: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
42: which results in false errors reported by lint(1).
43: Since this breaks the libc build itself, manual help is
1.180 wiz 44: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 45: $ (cd lib/libc && make MKLINT=no dependall install)
46:
1.177 christos 47: 20080813:
48: MKDEBUG build was broken because the .depend files did not know
49: about .go files. You need to remove all .depend files and rebuild.
50:
1.175 simonb 51: 20080731:
52: WAPBL (metadata journaling support) has been added, but at this
53: time isn't backwards compatible with pre-WAPBL aware kernels
54: and userland (fsck_ffs in particular). Please make sure you
55: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 56: especially an uncleanly mounted journaled filesystem. WAPBL
57: also requires the super block to be in the UFS2 format. You
58: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 59:
1.174 lukem 60: 20080721:
61: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
62: isn't defined.
63:
1.173 freza 64: 20080531:
65: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
66: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
67: utility needs to be rebuilt and reinstalled as older binaries
68: won't work correctly. The following sequence of commands:
69:
70: $ (cd sys/sys/ && nbmake-$arch includes)
71: $ (cd sbin/drvctl/ && nbmake-$arch clean)
72: $ (cd sbin/drvctl/ && nbmake-$arch all)
73:
74: leaves new drvctl utility in sbin/drvctl build directory.
75:
1.172 lukem 76: 20080503:
77: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
78:
1.171 he 79: 20080521:
80: For a while, unprivileged UPDATE builds would fail to
81: succeed at the checkflist stage, complaining that
82: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
83: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
84: If you already hit this problem, update the .mk file,
85: remove ${DESTDIR}/stand/<arch>, and re-run the build.
86:
1.174 lukem 87: 20080303:
88: Linker warnings are now fatal if $WARNS>0.
89:
1.170 christos 90: 20080126:
91: The posix_fadvise system call has been changed from an assembly
92: stub, to a c file that calls an assembly stub. You need to
93: 'rm -f posix_fadvise.* .depend' in the libc build directory to
94: avoid using the old assembly stub.
95:
1.168 joerg 96: 20071209:
97: The acpiec(4) driver has been split into two attachments. If you
98: get ACPI errors before the attachment, please update your kernel
1.169 wiz 99: configuration file appropriately or see GENERIC for more details.
1.168 joerg 100:
1.166 xtraeme 101: 20071115:
102: The it(4) driver has been renamed to itesio(4) and the old port
103: argument specified in the kernel configuration file is not valid
104: anymore. The itesio(4) driver now uses the Super I/O address port
105: rather than the EC address port. Please update your kernel
1.167 wiz 106: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 107:
1.165 jmmv 108: 20071028:
109: The pccons(4) driver has been removed from the NetBSD/shark port.
110: You need to update any custom kernel configuration file you have
111: to remove any references to pccons (which includes removing the
112: now useless XSERVER option) and replace them with the correct
113: entries for the wscons driver. See the GENERIC configuration file
114: for more details.
115:
1.164 gdt 116: 20070913:
117: A latent bug in dhclient/dhcpd that caused it to be unable to
118: enumerate interfaces was fixed. The bug began to cause
119: problems after 20070911 when the kernel's SIOCGIFCONF
120: implementation was repaired. From 20070529 to 20070911 racoon
121: could not enumerate interfaces. (These are noted because
122: normal kernel/userspace version matching hygiene is not
123: sufficient to avoid this problem.) Ensure that both kernel
124: and userland are from after 20070913.
125:
1.163 joerg 126: 20070703:
127: nbinstall has been renamed as it calls the target specific and
128: the logic to pass down STRIP from mk been removed. This forces
129: a re-installation of tools.
130:
1.161 dsl 131: 20070422:
132: The way OS emulations lookup filenames inside the emulation root
133: has been changed. Rather than modify the pathname (and copy back
134: to userspace) namei() and lookup() directly check the emulation
135: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 136: root file system will be relative to that file system - unless they
1.161 dsl 137: start /../ this is useful when the emulated root is a real install
138: that has such links.
139: This might affect symlinks that have been added to reference outside
140: the emulated root.
141:
1.160 jmcneill 142: 20070412:
143: The pckbc driver on sgimips IP32 has been removed. Use macekbc
144: instead. See the GENERIC32_IP3x kernel configuration for an
145: example.
146:
1.159 gdt 147: 20070319:
148: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
149: on many platforms due to incorrect flags settings. If you
150: updated and built after about 20070315, do "nbmake-$arch
151: cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
152: rebuild of object files that might have been built
153: incorrectly, and ensure that you have at least
154: src/lib/libc/Makefile 1.130.
155:
1.158 dbj 156: 20070210:
157: src/sys/sys/{sa.h,savar.h} were removed.
158: find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
159: | xargs egrep -l '/sa.h|/savar.h' | xargs rm
160: will allow dependencies on those files to get get rebuilt
161:
1.157 apb 162: 20070209:
163: The threading model was changed when the newlock2 branch
164: was merged to NetBSD-current. If you boot with a new
165: kernel (version 4.99.10), then you also need a new pthread
166: library (/usr/lib/libpthread.so.0.7). If you boot with
167: an old kernel, then you need the old pthread library
168: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
169: the pthread library in sync, old threaded applications should
170: continue to work with an old or new kernel. Note that named(8)
171: is the only threaded application in the base system.
172:
1.154 he 173: 20061214:
174: Following the move of string_to_flags() and flags_to_string()
175: from the bin/ls/ sources to libutil, users doing UPDATE builds
176: will need to do a "make cleandir" in
177: tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
178: bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
1.156 he 179: usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
180: as the installation images in distrib/
1.154 he 181: in order to excise stale references to the old stat_flags.h header
182: file in the ls sources -- stat_flags.h has been removed.
183:
1.152 christos 184: 20061108:
185: The configure script used in the src/tools/gcc compiler has been
186: changed to indicate that our libc has ssp support built-in and
187: does not depend on -lssp and -lssp-nonshared. You'll need to
188: make clean in src/tools/gcc first to rebuild the compiler.
189:
1.151 rpaulo 190: 20061009:
191: The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
192: available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
193:
1.150 bjh21 194: 20060814:
195: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
196: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
197: kernel configuration for an example. X servers from the last
198: few years should cope.
199:
1.149 christos 200: 20060703:
201: MPACPI is no more. We always configure PCI interrupts using ACPI
202: if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
203: to ACPI_SCANPCI. Thanks to work from fvdl.
204:
1.148 dogcow 205: 20060627:
206: socket(2) has changed, and its system call has been versioned.
207: For userlands with the old version of socket(2), make sure that
208: your kernel has 'options COMPAT_30' set, or else 'bad system call'
209: errors will result.
210:
1.1 abs 211: Hints for a more successful build:
212: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 213: Use build.sh, but do not use its "expert mode":
1.132 jmmv 214: This will automatically build the tools in the
1.123 jmc 215: correct order, and it will keep the tools and the
216: new build products from interfering with the running
217: system. This will allow you to ignore most of the
218: other advice in this file.
1.2 mrg 219: Build a new kernel first:
220: This makes sure that any new system calls or features
221: expected by the new userland will be present. This
222: helps to avoid critical errors when upgrading.
1.1 abs 223: Use object directories:
224: This helps to keep stale object
225: files from polluting the build if a Makefile "forgets"
226: about one. It also makes it easier to clean up after
227: a build. It's also necessary if you want to use the
228: same source tree for multiple machines.
1.123 jmc 229: To use object directories with build.sh:
230: a) invoke build.sh with the "-M" or "-O" options.
231: To use object directories without using build.sh:
1.1 abs 232: a) cd /usr/src ; make cleandir
1.2 mrg 233: b) Add "OBJMACHINE=yes" to /etc/mk.conf
234: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 235: d) cd /usr/src ; make build
1.2 mrg 236: Note that running "make obj" in a directory will create
237: in obj.$MACHINE directory.
1.1 abs 238: Build to a DESTDIR:
1.123 jmc 239: This helps to keep old installed files (especially libraries)
240: from interfering with the new build.
241: To build to a DESTDIR with build.sh, use the "-D" option.
242: To build to a DESTDIR without using build.sh, set the DESTDIR
243: environment variable before running make build. It should be
244: set to the pathname of an initially empty directory.
245: Problems: if you do not use build.sh, you might need to
246: update critical utilities without using DESTDIR since
247: nothing is executed from what is installed in DESTDIR.
248: (See critical utils, below.)
1.1 abs 249: Build often:
250: This keeps critical utilities current enough to not choke
251: on any other part of the source tree that depends on up to
1.123 jmc 252: date functionality. If you use build.sh, you should not have
253: this problem.
1.1 abs 254:
255: What to do if things don't work:
256: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
257: When things don't work there is usually a few things that commonly
258: should be done.
259: 1) make includes
260: This should be done automatically by make build.
261: 2) cd share/mk && make install
262: Again, automatically done by make build.
263:
264: Failsafe rebuild of a small part of the tree:
265: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
266: To make sure you rebuild something correctly you want to do
267: something like the following:
268: 1) Make sure the includes and .mk files are up to date.
269: 2) Make sure any program used to build the particular
270: utility is up to date. (yacc, lex, etc...)
271: 3) cd ...path/to/util...
272: make cleandir
273: rm ...all obj directories...
274: make cleandir # yes, again
275: make obj
276: make depend && make
277:
278: Failsafe rebuild of the entire tree:
279: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
280: If you really want to make sure the source tree is clean and
1.2 mrg 281: ready for a build try the following. Note that sourcing /etc/mk.conf
282: (a make(1) Makefile) in this manner is not right, and will not work
283: for anyone who uses any make(1) features in /etc/mk.conf.
