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.

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