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.

1.179 tsutsui 20: 20081122:
21: On i386 and amd64, various kernel options(4) in GENERIC including
1.180 ! wiz 22: file systems have been disabled and moved into kernel modules.
! 23: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 24: following files as well as a new GENERIC kernel:
25:
26: - build and install kernel modules from src/sys/modules
27:
28: - install the latest bootloader, which will load a module
1.180 ! wiz 29: for the file system from which the kernel is loaded automatically
1.179 tsutsui 30:
1.180 ! wiz 31: If you have to load your kernel from a file system which is not of
! 32: the same type as the root file system, you have to load the necessary
! 33: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 34:
1.178 lukem 35: 20080827:
36: If you built and installed a libc from sources between
37: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
38: which results in false errors reported by lint(1).
39: Since this breaks the libc build itself, manual help is
1.180 ! wiz 40: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 41: $ (cd lib/libc && make MKLINT=no dependall install)
42:
1.177 christos 43: 20080813:
44: MKDEBUG build was broken because the .depend files did not know
45: about .go files. You need to remove all .depend files and rebuild.
46:
1.175 simonb 47: 20080731:
48: WAPBL (metadata journaling support) has been added, but at this
49: time isn't backwards compatible with pre-WAPBL aware kernels
50: and userland (fsck_ffs in particular). Please make sure you
51: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 52: especially an uncleanly mounted journaled filesystem. WAPBL
53: also requires the super block to be in the UFS2 format. You
54: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 55:
1.174 lukem 56: 20080721:
57: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
58: isn't defined.
59:
1.173 freza 60: 20080531:
61: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
62: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
63: utility needs to be rebuilt and reinstalled as older binaries
64: won't work correctly. The following sequence of commands:
65:
66: $ (cd sys/sys/ && nbmake-$arch includes)
67: $ (cd sbin/drvctl/ && nbmake-$arch clean)
68: $ (cd sbin/drvctl/ && nbmake-$arch all)
69:
70: leaves new drvctl utility in sbin/drvctl build directory.
71:
1.172 lukem 72: 20080503:
73: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
74:
1.171 he 75: 20080521:
76: For a while, unprivileged UPDATE builds would fail to
77: succeed at the checkflist stage, complaining that
78: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
79: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
80: If you already hit this problem, update the .mk file,
81: remove ${DESTDIR}/stand/<arch>, and re-run the build.
82:
1.174 lukem 83: 20080303:
84: Linker warnings are now fatal if $WARNS>0.
85:
1.170 christos 86: 20080126:
87: The posix_fadvise system call has been changed from an assembly
88: stub, to a c file that calls an assembly stub. You need to
89: 'rm -f posix_fadvise.* .depend' in the libc build directory to
90: avoid using the old assembly stub.
91:
1.168 joerg 92: 20071209:
93: The acpiec(4) driver has been split into two attachments. If you
94: get ACPI errors before the attachment, please update your kernel
1.169 wiz 95: configuration file appropriately or see GENERIC for more details.
1.168 joerg 96:
1.166 xtraeme 97: 20071115:
98: The it(4) driver has been renamed to itesio(4) and the old port
99: argument specified in the kernel configuration file is not valid
100: anymore. The itesio(4) driver now uses the Super I/O address port
101: rather than the EC address port. Please update your kernel
1.167 wiz 102: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 103:
1.165 jmmv 104: 20071028:
105: The pccons(4) driver has been removed from the NetBSD/shark port.
106: You need to update any custom kernel configuration file you have
107: to remove any references to pccons (which includes removing the
108: now useless XSERVER option) and replace them with the correct
109: entries for the wscons driver. See the GENERIC configuration file
110: for more details.
111:
1.164 gdt 112: 20070913:
113: A latent bug in dhclient/dhcpd that caused it to be unable to
114: enumerate interfaces was fixed. The bug began to cause
115: problems after 20070911 when the kernel's SIOCGIFCONF
116: implementation was repaired. From 20070529 to 20070911 racoon
117: could not enumerate interfaces. (These are noted because
118: normal kernel/userspace version matching hygiene is not
119: sufficient to avoid this problem.) Ensure that both kernel
120: and userland are from after 20070913.
121:
1.163 joerg 122: 20070703:
123: nbinstall has been renamed as it calls the target specific and
124: the logic to pass down STRIP from mk been removed. This forces
125: a re-installation of tools.
126:
1.161 dsl 127: 20070422:
128: The way OS emulations lookup filenames inside the emulation root
129: has been changed. Rather than modify the pathname (and copy back
130: to userspace) namei() and lookup() directly check the emulation
131: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 132: root file system will be relative to that file system - unless they
1.161 dsl 133: start /../ this is useful when the emulated root is a real install
134: that has such links.
135: This might affect symlinks that have been added to reference outside
136: the emulated root.
137:
1.160 jmcneill 138: 20070412:
139: The pckbc driver on sgimips IP32 has been removed. Use macekbc
140: instead. See the GENERIC32_IP3x kernel configuration for an
141: example.
142:
1.159 gdt 143: 20070319:
144: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
145: on many platforms due to incorrect flags settings. If you
146: updated and built after about 20070315, do "nbmake-$arch
147: cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
148: rebuild of object files that might have been built
149: incorrectly, and ensure that you have at least
150: src/lib/libc/Makefile 1.130.
151:
1.158 dbj 152: 20070210:
153: src/sys/sys/{sa.h,savar.h} were removed.
154: find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
155: | xargs egrep -l '/sa.h|/savar.h' | xargs rm
156: will allow dependencies on those files to get get rebuilt
157:
1.157 apb 158: 20070209:
159: The threading model was changed when the newlock2 branch
160: was merged to NetBSD-current. If you boot with a new
161: kernel (version 4.99.10), then you also need a new pthread
162: library (/usr/lib/libpthread.so.0.7). If you boot with
163: an old kernel, then you need the old pthread library
164: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
165: the pthread library in sync, old threaded applications should
166: continue to work with an old or new kernel. Note that named(8)
167: is the only threaded application in the base system.
168:
1.154 he 169: 20061214:
170: Following the move of string_to_flags() and flags_to_string()
171: from the bin/ls/ sources to libutil, users doing UPDATE builds
172: will need to do a "make cleandir" in
173: tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
174: bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
1.156 he 175: usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
176: as the installation images in distrib/
1.154 he 177: in order to excise stale references to the old stat_flags.h header
178: file in the ls sources -- stat_flags.h has been removed.
179:
1.152 christos 180: 20061108:
181: The configure script used in the src/tools/gcc compiler has been
182: changed to indicate that our libc has ssp support built-in and
183: does not depend on -lssp and -lssp-nonshared. You'll need to
184: make clean in src/tools/gcc first to rebuild the compiler.
185:
1.151 rpaulo 186: 20061009:
187: The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
188: available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
189:
1.150 bjh21 190: 20060814:
191: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
192: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
193: kernel configuration for an example. X servers from the last
194: few years should cope.
195:
1.149 christos 196: 20060703:
197: MPACPI is no more. We always configure PCI interrupts using ACPI
198: if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
199: to ACPI_SCANPCI. Thanks to work from fvdl.
200:
1.148 dogcow 201: 20060627:
202: socket(2) has changed, and its system call has been versioned.
203: For userlands with the old version of socket(2), make sure that
204: your kernel has 'options COMPAT_30' set, or else 'bad system call'
205: errors will result.
206:
1.1 abs 207: Hints for a more successful build:
208: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 209: Use build.sh, but do not use its "expert mode":
1.132 jmmv 210: This will automatically build the tools in the
1.123 jmc 211: correct order, and it will keep the tools and the
212: new build products from interfering with the running
213: system. This will allow you to ignore most of the
214: other advice in this file.
1.2 mrg 215: Build a new kernel first:
216: This makes sure that any new system calls or features
217: expected by the new userland will be present. This
218: helps to avoid critical errors when upgrading.
1.1 abs 219: Use object directories:
220: This helps to keep stale object
221: files from polluting the build if a Makefile "forgets"
222: about one. It also makes it easier to clean up after
223: a build. It's also necessary if you want to use the
224: same source tree for multiple machines.
1.123 jmc 225: To use object directories with build.sh:
226: a) invoke build.sh with the "-M" or "-O" options.
227: To use object directories without using build.sh:
1.1 abs 228: a) cd /usr/src ; make cleandir
1.2 mrg 229: b) Add "OBJMACHINE=yes" to /etc/mk.conf
230: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 231: d) cd /usr/src ; make build
1.2 mrg 232: Note that running "make obj" in a directory will create
233: in obj.$MACHINE directory.
1.1 abs 234: Build to a DESTDIR:
1.123 jmc 235: This helps to keep old installed files (especially libraries)
236: from interfering with the new build.
237: To build to a DESTDIR with build.sh, use the "-D" option.
238: To build to a DESTDIR without using build.sh, set the DESTDIR
239: environment variable before running make build. It should be
240: set to the pathname of an initially empty directory.
241: Problems: if you do not use build.sh, you might need to
242: update critical utilities without using DESTDIR since
243: nothing is executed from what is installed in DESTDIR.
244: (See critical utils, below.)
1.1 abs 245: Build often:
246: This keeps critical utilities current enough to not choke
247: on any other part of the source tree that depends on up to
1.123 jmc 248: date functionality. If you use build.sh, you should not have
249: this problem.
1.1 abs 250:
251: What to do if things don't work:
252: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
253: When things don't work there is usually a few things that commonly
254: should be done.
255: 1) make includes
256: This should be done automatically by make build.
257: 2) cd share/mk && make install
258: Again, automatically done by make build.
259:
260: Failsafe rebuild of a small part of the tree:
261: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
262: To make sure you rebuild something correctly you want to do
263: something like the following:
264: 1) Make sure the includes and .mk files are up to date.
265: 2) Make sure any program used to build the particular
266: utility is up to date. (yacc, lex, etc...)
267: 3) cd ...path/to/util...
268: make cleandir
269: rm ...all obj directories...
270: make cleandir # yes, again
271: make obj
272: make depend && make
273:
274: Failsafe rebuild of the entire tree:
275: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
276: If you really want to make sure the source tree is clean and
1.2 mrg 277: ready for a build try the following. Note that sourcing /etc/mk.conf
278: (a make(1) Makefile) in this manner is not right, and will not work
279: for anyone who uses any make(1) features in /etc/mk.conf.
