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.

17: ^^^^^^^^^^^^^^^
1.138 lukem 18:
1.184 ! christos 19: 20090110:
! 20: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
! 21: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
! 22: 2. make sure build.sh completes and the binaries in a chroot work
! 23: before installing.
! 24: 3. If you don't use build.sh and you build directly to root, and
! 25: your build breaks in the middle, don't dispair. Make sure headers
! 26: are installed properly, and start building libraries first libc
! 27: and libutil, install them and then continue building all the
! 28: libraries in src/lib and src/gnu/lib and install them. Once
! 29: the new libraries are installed, you can restart the build.
! 30: 4. If you compile packages and you notice link time warnings,
! 31: you'll need to bump them and rebuild them.
1.183 pgoyette 32: 20081219:
33: config(1) has been updated, and one of the files it creates -
34: swapnetbsd.o - has changed format. You need to rebuild config
35: (done automatically by build.sh) and then you need to rerun
36: config on all kernel configuration files before rebuilding those
37: kernels.
38:
1.181 cube 39: 20081205:
40: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
41: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
42: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 43:
1.179 tsutsui 44: 20081122:
1.182 tsutsui 45: On i386, various kernel options(4) in GENERIC including
1.180 wiz 46: file systems have been disabled and moved into kernel modules.
47: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 48: following files as well as a new GENERIC kernel:
49:
50: - build and install kernel modules from src/sys/modules
51:
52: - install the latest bootloader, which will load a module
1.180 wiz 53: for the file system from which the kernel is loaded automatically
1.179 tsutsui 54:
1.180 wiz 55: If you have to load your kernel from a file system which is not of
56: the same type as the root file system, you have to load the necessary
57: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 58:
1.178 lukem 59: 20080827:
60: If you built and installed a libc from sources between
61: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
62: which results in false errors reported by lint(1).
63: Since this breaks the libc build itself, manual help is
1.180 wiz 64: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 65: $ (cd lib/libc && make MKLINT=no dependall install)
66:
1.177 christos 67: 20080813:
68: MKDEBUG build was broken because the .depend files did not know
69: about .go files. You need to remove all .depend files and rebuild.
70:
1.175 simonb 71: 20080731:
72: WAPBL (metadata journaling support) has been added, but at this
73: time isn't backwards compatible with pre-WAPBL aware kernels
74: and userland (fsck_ffs in particular). Please make sure you
75: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 76: especially an uncleanly mounted journaled filesystem. WAPBL
77: also requires the super block to be in the UFS2 format. You
78: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 79:
1.174 lukem 80: 20080721:
81: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
82: isn't defined.
83:
1.173 freza 84: 20080531:
85: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
86: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
87: utility needs to be rebuilt and reinstalled as older binaries
88: won't work correctly. The following sequence of commands:
89:
90: $ (cd sys/sys/ && nbmake-$arch includes)
91: $ (cd sbin/drvctl/ && nbmake-$arch clean)
92: $ (cd sbin/drvctl/ && nbmake-$arch all)
93:
94: leaves new drvctl utility in sbin/drvctl build directory.
95:
1.172 lukem 96: 20080503:
97: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
98:
1.171 he 99: 20080521:
100: For a while, unprivileged UPDATE builds would fail to
101: succeed at the checkflist stage, complaining that
102: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
103: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
104: If you already hit this problem, update the .mk file,
105: remove ${DESTDIR}/stand/<arch>, and re-run the build.
106:
1.174 lukem 107: 20080303:
108: Linker warnings are now fatal if $WARNS>0.
109:
1.170 christos 110: 20080126:
111: The posix_fadvise system call has been changed from an assembly
112: stub, to a c file that calls an assembly stub. You need to
113: 'rm -f posix_fadvise.* .depend' in the libc build directory to
114: avoid using the old assembly stub.
115:
1.168 joerg 116: 20071209:
117: The acpiec(4) driver has been split into two attachments. If you
118: get ACPI errors before the attachment, please update your kernel
1.169 wiz 119: configuration file appropriately or see GENERIC for more details.
1.168 joerg 120:
1.166 xtraeme 121: 20071115:
122: The it(4) driver has been renamed to itesio(4) and the old port
123: argument specified in the kernel configuration file is not valid
124: anymore. The itesio(4) driver now uses the Super I/O address port
125: rather than the EC address port. Please update your kernel
1.167 wiz 126: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 127:
1.165 jmmv 128: 20071028:
129: The pccons(4) driver has been removed from the NetBSD/shark port.
130: You need to update any custom kernel configuration file you have
131: to remove any references to pccons (which includes removing the
132: now useless XSERVER option) and replace them with the correct
133: entries for the wscons driver. See the GENERIC configuration file
134: for more details.
135:
1.164 gdt 136: 20070913:
137: A latent bug in dhclient/dhcpd that caused it to be unable to
138: enumerate interfaces was fixed. The bug began to cause
139: problems after 20070911 when the kernel's SIOCGIFCONF
140: implementation was repaired. From 20070529 to 20070911 racoon
141: could not enumerate interfaces. (These are noted because
142: normal kernel/userspace version matching hygiene is not
143: sufficient to avoid this problem.) Ensure that both kernel
144: and userland are from after 20070913.
145:
1.163 joerg 146: 20070703:
147: nbinstall has been renamed as it calls the target specific and
148: the logic to pass down STRIP from mk been removed. This forces
149: a re-installation of tools.
150:
1.161 dsl 151: 20070422:
152: The way OS emulations lookup filenames inside the emulation root
153: has been changed. Rather than modify the pathname (and copy back
154: to userspace) namei() and lookup() directly check the emulation
155: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 156: root file system will be relative to that file system - unless they
1.161 dsl 157: start /../ this is useful when the emulated root is a real install
158: that has such links.
159: This might affect symlinks that have been added to reference outside
160: the emulated root.
161:
1.160 jmcneill 162: 20070412:
163: The pckbc driver on sgimips IP32 has been removed. Use macekbc
164: instead. See the GENERIC32_IP3x kernel configuration for an
165: example.
166:
1.159 gdt 167: 20070319:
168: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
169: on many platforms due to incorrect flags settings. If you
170: updated and built after about 20070315, do "nbmake-$arch
171: cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
172: rebuild of object files that might have been built
173: incorrectly, and ensure that you have at least
174: src/lib/libc/Makefile 1.130.
175:
1.158 dbj 176: 20070210:
177: src/sys/sys/{sa.h,savar.h} were removed.
178: find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
179: | xargs egrep -l '/sa.h|/savar.h' | xargs rm
180: will allow dependencies on those files to get get rebuilt
181:
1.157 apb 182: 20070209:
183: The threading model was changed when the newlock2 branch
184: was merged to NetBSD-current. If you boot with a new
185: kernel (version 4.99.10), then you also need a new pthread
186: library (/usr/lib/libpthread.so.0.7). If you boot with
187: an old kernel, then you need the old pthread library
188: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
189: the pthread library in sync, old threaded applications should
190: continue to work with an old or new kernel. Note that named(8)
191: is the only threaded application in the base system.
192:
1.154 he 193: 20061214:
194: Following the move of string_to_flags() and flags_to_string()
195: from the bin/ls/ sources to libutil, users doing UPDATE builds
196: will need to do a "make cleandir" in
197: tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
198: bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
1.156 he 199: usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
200: as the installation images in distrib/
1.154 he 201: in order to excise stale references to the old stat_flags.h header
202: file in the ls sources -- stat_flags.h has been removed.
203:
1.152 christos 204: 20061108:
205: The configure script used in the src/tools/gcc compiler has been
206: changed to indicate that our libc has ssp support built-in and
207: does not depend on -lssp and -lssp-nonshared. You'll need to
208: make clean in src/tools/gcc first to rebuild the compiler.
209:
1.151 rpaulo 210: 20061009:
211: The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
212: available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
213:
1.150 bjh21 214: 20060814:
215: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
216: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
217: kernel configuration for an example. X servers from the last
218: few years should cope.
219:
1.149 christos 220: 20060703:
221: MPACPI is no more. We always configure PCI interrupts using ACPI
222: if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
223: to ACPI_SCANPCI. Thanks to work from fvdl.
224:
1.148 dogcow 225: 20060627:
226: socket(2) has changed, and its system call has been versioned.
227: For userlands with the old version of socket(2), make sure that
228: your kernel has 'options COMPAT_30' set, or else 'bad system call'
229: errors will result.
230:
1.1 abs 231: Hints for a more successful build:
232: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 233: Use build.sh, but do not use its "expert mode":
1.132 jmmv 234: This will automatically build the tools in the
1.123 jmc 235: correct order, and it will keep the tools and the
236: new build products from interfering with the running
237: system. This will allow you to ignore most of the
238: other advice in this file.
1.2 mrg 239: Build a new kernel first:
240: This makes sure that any new system calls or features
241: expected by the new userland will be present. This
242: helps to avoid critical errors when upgrading.
1.1 abs 243: Use object directories:
244: This helps to keep stale object
245: files from polluting the build if a Makefile "forgets"
246: about one. It also makes it easier to clean up after
247: a build. It's also necessary if you want to use the
248: same source tree for multiple machines.
1.123 jmc 249: To use object directories with build.sh:
250: a) invoke build.sh with the "-M" or "-O" options.
251: To use object directories without using build.sh:
1.1 abs 252: a) cd /usr/src ; make cleandir
1.2 mrg 253: b) Add "OBJMACHINE=yes" to /etc/mk.conf
254: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 255: d) cd /usr/src ; make build
1.2 mrg 256: Note that running "make obj" in a directory will create
257: in obj.$MACHINE directory.
1.1 abs 258: Build to a DESTDIR:
1.123 jmc 259: This helps to keep old installed files (especially libraries)
260: from interfering with the new build.
261: To build to a DESTDIR with build.sh, use the "-D" option.
262: To build to a DESTDIR without using build.sh, set the DESTDIR
263: environment variable before running make build. It should be
264: set to the pathname of an initially empty directory.
265: Problems: if you do not use build.sh, you might need to
266: update critical utilities without using DESTDIR since
267: nothing is executed from what is installed in DESTDIR.
268: (See critical utils, below.)
1.1 abs 269: Build often:
270: This keeps critical utilities current enough to not choke
271: on any other part of the source tree that depends on up to
1.123 jmc 272: date functionality. If you use build.sh, you should not have
273: this problem.
1.1 abs 274:
275: What to do if things don't work:
276: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
277: When things don't work there is usually a few things that commonly
278: should be done.
279: 1) make includes
280: This should be done automatically by make build.
281: 2) cd share/mk && make install
282: Again, automatically done by make build.
283:
284: Failsafe rebuild of a small part of the tree:
285: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
286: To make sure you rebuild something correctly you want to do
287: something like the following:
288: 1) Make sure the includes and .mk files are up to date.
289: 2) Make sure any program used to build the particular
290: utility is up to date. (yacc, lex, etc...)
291: 3) cd ...path/to/util...
292: make cleandir
293: rm ...all obj directories...
294: make cleandir # yes, again
295: make obj
296: make depend && make
297:
298: Failsafe rebuild of the entire tree:
299: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
300: If you really want to make sure the source tree is clean and
1.2 mrg 301: ready for a build try the following. Note that sourcing /etc/mk.conf
302: (a make(1) Makefile) in this manner is not right, and will not work
303: for anyone who uses any make(1) features in /etc/mk.conf.
