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.

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