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