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.

1.183 ! pgoyette 19: 20081219:
! 20: config(1) has been updated, and one of the files it creates -
! 21: swapnetbsd.o - has changed format. You need to rebuild config
! 22: (done automatically by build.sh) and then you need to rerun
! 23: config on all kernel configuration files before rebuilding those
! 24: kernels.
! 25:
1.181 cube 26: 20081205:
27: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
28: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
29: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 30:
1.179 tsutsui 31: 20081122:
1.182 tsutsui 32: On i386, various kernel options(4) in GENERIC including
1.180 wiz 33: file systems have been disabled and moved into kernel modules.
34: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 35: following files as well as a new GENERIC kernel:
36:
37: - build and install kernel modules from src/sys/modules
38:
39: - install the latest bootloader, which will load a module
1.180 wiz 40: for the file system from which the kernel is loaded automatically
1.179 tsutsui 41:
1.180 wiz 42: If you have to load your kernel from a file system which is not of
43: the same type as the root file system, you have to load the necessary
44: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 45:
1.178 lukem 46: 20080827:
47: If you built and installed a libc from sources between
48: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
49: which results in false errors reported by lint(1).
50: Since this breaks the libc build itself, manual help is
1.180 wiz 51: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 52: $ (cd lib/libc && make MKLINT=no dependall install)
53:
1.177 christos 54: 20080813:
55: MKDEBUG build was broken because the .depend files did not know
56: about .go files. You need to remove all .depend files and rebuild.
57:
1.175 simonb 58: 20080731:
59: WAPBL (metadata journaling support) has been added, but at this
60: time isn't backwards compatible with pre-WAPBL aware kernels
61: and userland (fsck_ffs in particular). Please make sure you
62: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 63: especially an uncleanly mounted journaled filesystem. WAPBL
64: also requires the super block to be in the UFS2 format. You
65: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 66:
1.174 lukem 67: 20080721:
68: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
69: isn't defined.
70:
1.173 freza 71: 20080531:
72: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
73: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
74: utility needs to be rebuilt and reinstalled as older binaries
75: won't work correctly. The following sequence of commands:
76:
77: $ (cd sys/sys/ && nbmake-$arch includes)
78: $ (cd sbin/drvctl/ && nbmake-$arch clean)
79: $ (cd sbin/drvctl/ && nbmake-$arch all)
80:
81: leaves new drvctl utility in sbin/drvctl build directory.
82:
1.172 lukem 83: 20080503:
84: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
85:
1.171 he 86: 20080521:
87: For a while, unprivileged UPDATE builds would fail to
88: succeed at the checkflist stage, complaining that
89: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
90: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
91: If you already hit this problem, update the .mk file,
92: remove ${DESTDIR}/stand/<arch>, and re-run the build.
93:
1.174 lukem 94: 20080303:
95: Linker warnings are now fatal if $WARNS>0.
96:
1.170 christos 97: 20080126:
98: The posix_fadvise system call has been changed from an assembly
99: stub, to a c file that calls an assembly stub. You need to
100: 'rm -f posix_fadvise.* .depend' in the libc build directory to
101: avoid using the old assembly stub.
102:
1.168 joerg 103: 20071209:
104: The acpiec(4) driver has been split into two attachments. If you
105: get ACPI errors before the attachment, please update your kernel
1.169 wiz 106: configuration file appropriately or see GENERIC for more details.
1.168 joerg 107:
1.166 xtraeme 108: 20071115:
109: The it(4) driver has been renamed to itesio(4) and the old port
110: argument specified in the kernel configuration file is not valid
111: anymore. The itesio(4) driver now uses the Super I/O address port
112: rather than the EC address port. Please update your kernel
1.167 wiz 113: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 114:
1.165 jmmv 115: 20071028:
116: The pccons(4) driver has been removed from the NetBSD/shark port.
117: You need to update any custom kernel configuration file you have
118: to remove any references to pccons (which includes removing the
119: now useless XSERVER option) and replace them with the correct
120: entries for the wscons driver. See the GENERIC configuration file
121: for more details.
122:
1.164 gdt 123: 20070913:
124: A latent bug in dhclient/dhcpd that caused it to be unable to
125: enumerate interfaces was fixed. The bug began to cause
126: problems after 20070911 when the kernel's SIOCGIFCONF
127: implementation was repaired. From 20070529 to 20070911 racoon
128: could not enumerate interfaces. (These are noted because
129: normal kernel/userspace version matching hygiene is not
130: sufficient to avoid this problem.) Ensure that both kernel
131: and userland are from after 20070913.
132:
1.163 joerg 133: 20070703:
134: nbinstall has been renamed as it calls the target specific and
135: the logic to pass down STRIP from mk been removed. This forces
136: a re-installation of tools.
137:
1.161 dsl 138: 20070422:
139: The way OS emulations lookup filenames inside the emulation root
140: has been changed. Rather than modify the pathname (and copy back
141: to userspace) namei() and lookup() directly check the emulation
142: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 143: root file system will be relative to that file system - unless they
1.161 dsl 144: start /../ this is useful when the emulated root is a real install
145: that has such links.
146: This might affect symlinks that have been added to reference outside
147: the emulated root.
148:
1.160 jmcneill 149: 20070412:
150: The pckbc driver on sgimips IP32 has been removed. Use macekbc
151: instead. See the GENERIC32_IP3x kernel configuration for an
152: example.
153:
1.159 gdt 154: 20070319:
155: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
156: on many platforms due to incorrect flags settings. If you
157: updated and built after about 20070315, do "nbmake-$arch
158: cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
159: rebuild of object files that might have been built
160: incorrectly, and ensure that you have at least
161: src/lib/libc/Makefile 1.130.
162:
1.158 dbj 163: 20070210:
164: src/sys/sys/{sa.h,savar.h} were removed.
165: find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
166: | xargs egrep -l '/sa.h|/savar.h' | xargs rm
167: will allow dependencies on those files to get get rebuilt
168:
1.157 apb 169: 20070209:
170: The threading model was changed when the newlock2 branch
171: was merged to NetBSD-current. If you boot with a new
172: kernel (version 4.99.10), then you also need a new pthread
173: library (/usr/lib/libpthread.so.0.7). If you boot with
174: an old kernel, then you need the old pthread library
175: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
176: the pthread library in sync, old threaded applications should
177: continue to work with an old or new kernel. Note that named(8)
178: is the only threaded application in the base system.
179:
1.154 he 180: 20061214:
181: Following the move of string_to_flags() and flags_to_string()
182: from the bin/ls/ sources to libutil, users doing UPDATE builds
183: will need to do a "make cleandir" in
184: tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
185: bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
1.156 he 186: usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
187: as the installation images in distrib/
1.154 he 188: in order to excise stale references to the old stat_flags.h header
189: file in the ls sources -- stat_flags.h has been removed.
190:
1.152 christos 191: 20061108:
192: The configure script used in the src/tools/gcc compiler has been
193: changed to indicate that our libc has ssp support built-in and
194: does not depend on -lssp and -lssp-nonshared. You'll need to
195: make clean in src/tools/gcc first to rebuild the compiler.
196:
1.151 rpaulo 197: 20061009:
198: The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
199: available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
200:
1.150 bjh21 201: 20060814:
202: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
203: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
204: kernel configuration for an example. X servers from the last
205: few years should cope.
206:
1.149 christos 207: 20060703:
208: MPACPI is no more. We always configure PCI interrupts using ACPI
209: if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
210: to ACPI_SCANPCI. Thanks to work from fvdl.
211:
1.148 dogcow 212: 20060627:
213: socket(2) has changed, and its system call has been versioned.
214: For userlands with the old version of socket(2), make sure that
215: your kernel has 'options COMPAT_30' set, or else 'bad system call'
216: errors will result.
217:
1.1 abs 218: Hints for a more successful build:
219: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 220: Use build.sh, but do not use its "expert mode":
1.132 jmmv 221: This will automatically build the tools in the
1.123 jmc 222: correct order, and it will keep the tools and the
223: new build products from interfering with the running
224: system. This will allow you to ignore most of the
225: other advice in this file.
1.2 mrg 226: Build a new kernel first:
227: This makes sure that any new system calls or features
228: expected by the new userland will be present. This
229: helps to avoid critical errors when upgrading.
1.1 abs 230: Use object directories:
231: This helps to keep stale object
232: files from polluting the build if a Makefile "forgets"
233: about one. It also makes it easier to clean up after
234: a build. It's also necessary if you want to use the
235: same source tree for multiple machines.
1.123 jmc 236: To use object directories with build.sh:
237: a) invoke build.sh with the "-M" or "-O" options.
238: To use object directories without using build.sh:
1.1 abs 239: a) cd /usr/src ; make cleandir
1.2 mrg 240: b) Add "OBJMACHINE=yes" to /etc/mk.conf
241: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 242: d) cd /usr/src ; make build
1.2 mrg 243: Note that running "make obj" in a directory will create
244: in obj.$MACHINE directory.
1.1 abs 245: Build to a DESTDIR:
1.123 jmc 246: This helps to keep old installed files (especially libraries)
247: from interfering with the new build.
248: To build to a DESTDIR with build.sh, use the "-D" option.
249: To build to a DESTDIR without using build.sh, set the DESTDIR
250: environment variable before running make build. It should be
251: set to the pathname of an initially empty directory.
252: Problems: if you do not use build.sh, you might need to
253: update critical utilities without using DESTDIR since
254: nothing is executed from what is installed in DESTDIR.
255: (See critical utils, below.)
1.1 abs 256: Build often:
257: This keeps critical utilities current enough to not choke
258: on any other part of the source tree that depends on up to
1.123 jmc 259: date functionality. If you use build.sh, you should not have
260: this problem.
1.1 abs 261:
262: What to do if things don't work:
263: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
264: When things don't work there is usually a few things that commonly
265: should be done.
266: 1) make includes
267: This should be done automatically by make build.
268: 2) cd share/mk && make install
269: Again, automatically done by make build.
270:
271: Failsafe rebuild of a small part of the tree:
272: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
273: To make sure you rebuild something correctly you want to do
274: something like the following:
275: 1) Make sure the includes and .mk files are up to date.
276: 2) Make sure any program used to build the particular
277: utility is up to date. (yacc, lex, etc...)
278: 3) cd ...path/to/util...
279: make cleandir
280: rm ...all obj directories...
281: make cleandir # yes, again
282: make obj
283: make depend && make
284:
285: Failsafe rebuild of the entire tree:
286: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
287: If you really want to make sure the source tree is clean and
1.2 mrg 288: ready for a build try the following. Note that sourcing /etc/mk.conf
289: (a make(1) Makefile) in this manner is not right, and will not work
290: for anyone who uses any make(1) features in /etc/mk.conf.
