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.

! 20:
! 21: Due to the recent rototill of tools/compat it's crucial one starts
! 22: from a clean objdir under tools/*.
! 23:
! 24: This is mostly due to generated files (yacc and lex sources) needing
! 25: to be generated w. new rules from bsd.hostprog.mk.
! 26:
! 27: The safest course is to rm -rf all objects under tools before building.

1.121 lukem 29: 20040516:
30: The end-user modifiable X11 configuration has been moved
31: from /usr/X11R6/lib/X11/<dir> to /etc/X11/<dir>.
32: Ensure that src and xsrc is up to date, and run
33: "make cleandir" in src/x11 before your next build.
34:
1.119 atatat 35: 20040426:
36: Support for the original dynamic sysctl node structure has
37: been removed in favor of the newer layout. This affects
38: consumers of the create and delete interface, as well as
39: the dynamic discovery mechanism. This is believed only to
40: be the sysctl(8) binary itself, at this point in time, so
41: the only effect of this should be that a sysctl binary
42: built from sources dated between 2003/12/04 and 2004/03/24
43: will not work on a kernel built from sources dated after
44: 2004/04/25. If you need a new sysctl binary but build.sh
45: does not work, make sure that your revision of
1.120 atatat 46: src/sys/sys/sysctl.h is 1.112 (or later), and then the
47: do the following:
1.119 atatat 48:
1.120 atatat 49: cd /usr/src (or wherever your source tree is)
50: make USETOOLS=no includes
51: cd lib/libc
52: make USETOOLS=no dependall install
53: cd ../../sbin/sysctl
1.119 atatat 54: make USETOOLS=no dependall install
55:
1.122 itojun 56: If you are using older sysctl binary, GNU autoconf would fail to
57: identify your machine architecture, and tries to build binary for
58: "unknown-unknown-netbsd20F" or something like that. if that happens,
59: make sure to follow the above steps.
60:
1.118 dbj 61: 20040425:
62: The ffs superblock issues listed below under 20040109 and 20030402
63: are now automatically addressed by the /etc/rc.d/fixsb script or by
64: sysinst when it checks a a filesystem. The manual fsck_ffs -b16 -c4
65: invocation mentioned below will continue to work and is now
66: automated by those scripts. Note that under certain circumstances,
67: affected filesystems upgraded to a -current kernel first before
68: upgrading their userland with the fixsb and fsck_ffs fixes may
69: encounter a 'freeing free inode' panic when writing to the affected
70: filesystem, so it is a good idea to repair the filesystem as soon as
71: possible. For more details on the fixsb script, see pr install/25138.
72:
1.115 christos 73: 20040418:
1.121 lukem 74: statfs(2) and friends have been replaced with statvfs(2). Before
1.115 christos 75: installing a newly build userland make sure that you are running
76: a newly built kernel with COMPAT_20 set. In addition your libc
77: build might not work (undefined SYS_statfs symbol) because make
78: clean does not know how to remove files it does not know about
1.116 christos 79: anymore. Manually remove all generated .S sources and objects
80: from the libc build directory.
1.115 christos 81:
1.114 jmc 82: 20040326:
83: The method by which athhal-elf.o gets pulled into i386 kernel builds
1.117 jmc 84: has been changed. The file is now stored as a uuencoded file in CVS
1.114 jmc 85: and the generated Makefile will use the new .uue rules from bsd.file.mk
86: to build it.
87:
88: This means you must have the latest bsd.files.mk installed when
89: building a kernel without USETOOLS=yes.
90:
1.113 dan 91: 20040318:
92: A bug in the cgd(4) blowfish code was corrected, without
93: provision of backwards compatibility, after several public
94: notices over several months. Users of cgd with blowfish cipher
95: ONLY must dump their data before updating their kernels, and
96: recreate cgd's and restore data using the new kernel. See
97: (recent message to current-users, URL when mail-index has updated)
98:
1.108 bjh21 99: 20040313:
100: On acorn32, the opms and qms drivers have been withdrawn, and
101: the old wsqms driver is now called qms. Kernel config files
102: will need updating. See the ones in sys/arch/acorn32/conf
103: for examples.
104:
1.106 bjh21 105: 20040125:
106: On acorn32, the beep and sysbeep devices are no longer
107: needed, and will need to be deleted from kernel configuration
108: files.
1.105 bjh21 109:
1.102 dbj 110: 20040109:
111: Compatibility for old ffs superblock layouts has been
112: added, and the restrictive fsck checks have been reenabled
113: when using those layouts. If you have been using -current
114: since 20030402, you may find that fsck again signals fatal
1.110 dbj 115: superblock mismatches. To repair, make sure you have
1.111 simonb 116: an updated fsck_ffs and then you can use fsck_ffs -b 16 -c 4
1.109 dbj 117: to complete the filesystem upgrade. A message has
1.111 simonb 118: been added to the kernel which should detect this problem.
119: See the following discussion for more information:
1.112 keihan 120: http://mail-index.NetBSD.org/current-users/2004/01/11/0022.html
1.102 dbj 121:
1.99 mrg 122: 20031203:
1.100 keihan 123: New binutils builds may fail due to old dependencies.
1.99 mrg 124: It's necessary to "make cleandir" to ensure that
125: the dependencies will be rebuilt correctly.
1.98 wiz 126:
127: 20031111:
128: A newer mkdep is needed. Error noting that is
129: cc: Ambiguous abbreviation --
1.97 lukem 130:
131: 20031008:
132: /usr/include/sys/disklabel_mbr.h was removed.
133: It's necessary to "make cleandir" to ensure that
134: the dependencies will be rebuilt correctly.
1.96 christos 135:
1.109 dbj 136: 20031007:
1.111 simonb 137: A sign exension bug was fixed which set all the high bits
138: of our newly expanded ffs fs_flags. This should only
139: affect users who installed or upgraded in September of 2003.
1.109 dbj 140: A small utility program was posted to tech-kern which
1.111 simonb 141: should fix this problem, and a warning message was added
142: to the kernel which should discover and warn about it. See
143: http://mail-index.NetBSD.org/tech-kern/2003/10/07/0005.html
1.109 dbj 144:
1.96 christos 145: 20030906:
146: With the addition of siginfo support the old signal trampoline
147: code has been deprecated to COMPAT_16. Make sure that your running
148: kernel has COMPAT_16 enabled before building userland.
1.94 christos 149:
150: 20030801:
1.95 wiz 151: With the new openssl, there is some header and library shuffling.
1.94 christos 152: rm -f /usr/include/des.h /usr/include/kerberosIV/* /lib/libdes* \
1.95 wiz 153: /usr/lib/libdes* before building.
1.92 wiz 154:
155: 20030703:
156: Texinfo was updated to 4.6. To avoid failures when trying to
157: build the included texinfo files, do:
158:
159: cd src/gnu/usr.bin/texinfo
160: make MKINFO=no dependall install
1.90 wiz 161:
162: 20030630:
1.101 junyoung 163: Groff was updated to 1.19; it's probably necessary to do
1.91 wiz 164: cd share/mk && make install
1.90 wiz 165: cd src/gnu/usr.bin/groff
166: make MKMAN=no dependall install
167: (untested).
1.89 christos 168:
169: 20030516:
170: Due to bugs in the export handling code, invalid export lines
171: were accepted before and caused the kernel to panic when
172: mountd got restarted because it freed memory that had already
173: been freed. This has been fixed and the kernel checks
174: export addresses very strictly. If you upgrade your kernel,
175: make sure you also upgrade mountd, because if your export
176: file contains lines with an old inet4 address syntax (i.e.
177: a.b.c or a.b or a), they will get rejected by the new kernel.
1.87 bjh21 178:
179: 20030402:
180: The superblock layout for FFS was changed. If you have 1.6
181: fsck binaries, they will signal a fatal superblock mismatch
182: with the first alternate, because they compare too many
183: fields (even ones that aren't useful). If possible, upgrade
184: your fsck_ffs binary before using a new kernel.
185: None of this signals actual filesystem damage.
1.85 atatat 186:
187: 20030324:
188: sendmail version 8.12.8 was imported. Since sendmail is
189: now setgid to the smmsp group, and runs in "collection"
190: mode for most common activities, there is a new config
191: file called submit.cf that needs to live in /etc/mail.
192: The generic submit.cf sample in /usr/share/sendmail/cf
193: is named netbsd-msp.cf. Upgrading your regular sendmail
194: configuration file is also strongly advised.
195:
196: See the section named "MESSAGE SUBMISSION PROGRAM" in
197: the updated /usr/share/sendmail/README file for more
198: information.
1.82 wiz 199:
200: 20030117:
201: Texinfo was updated to 4.3. To avoid failures when trying to
202: build the included texinfo files, do:
203:
204: cd src/gnu/usr.bin/texinfo
205: make MKINFO=no dependall install
1.81 lukem 206:
207: 20021223:
208: The METALOG format changed slightly, to remove the leading
209: "${DESTDIR}" from path names.
210: This only affects people building with UNPRIVED.
211: For complete safety, remove the DESTDIR entirely and
212: update tools/mtree, before running make build.
1.88 itojun 213:
214: 20021219:
215: CVS repository layout was changed. See the following for details
216: if you are using (anonymous) cvs to update your tree.
217:
1.93 salo 218: http://mail-index.NetBSD.org/netbsd-announce/2002/12/19/0000.html
1.80 lukem 219:
220: 20021219:
221: install(1) had a '-N dbdir' option added, to specify an
222: alternate location to look up users & groups (instead
223: of the host system passwd(5) and group(5) databases).
224:
225: The build system was modified to take advantage of
226: this option (using ${NETBSDSRCDIR}/etc), so if you
1.83 kei 227: use USETOOLS==no, you may have to rebuild and
1.80 lukem 228: reinstall usr.bin/xinstall first.
1.78 lukem 229:
230: 20021130:
231: fparseln(3) moved from libutil to libc.
232: If building to DESTDIR=/, reinstall the includes
233: and rebuild libc:
234: make includes
235: make do-lib-libc
236: If using build.sh, "cd tools/compat && make clean"
237: before rebuilding the tools.
1.77 lukem 238:
239: 20021126:
240: The mk.conf(5) variable SYS_INCLUDE has been deprecated,
241: including the optional "SYS_INCLUDE=symlinks" support.
242: All header files, including <sys/*.h> are copied into
243: /usr/include.
1.76 thorpej 244:
245: 20021121:
246: The C run-time support files crtbegin.o and crtend.o
247: (and their companions crtbeginS.o and crtendS.o) were
248: split up, with new crti.o and crtn.o files resulting.
249: This means that libtool needs to be rebuilt once the
250: new libraries are installed. The process of rebuilding
251: libtool will cause it to automatically notice the new
252: required files, but it *must* be rebuilt in order to
253: do this.
254:
255: An out-of-date libtool will result in shared libraries
256: which lack _init() and _fini() routines, which means that
257: their global contructors/destructors will not be invoked.
1.75 thorpej 258:
259: 20021121:
260: A bug related to how ARM ELF objects were tagged has been
261: corrected.
262:
263: NetBSD ARM ELF uses the soft-VFP floating point model by
264: default. However, the assembler lacked support for marking
265: objects as using the VFP floating point format, and the
1.79 wiz 266: compiler was not properly passing the flag indicating "soft-VFP"
1.75 thorpej 267: to the assembler.
268:
269: Unfortunately, this means that the linker will now consider
270: old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be
271: incompatible with new (properly marked) objects.
272:
273: The problem will only manifest itself if you attempt to compile
274: a new program using the fixed toolchain, and link that program
275: against old libraries which do not have the proper "softvfp"
276: markings. ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES
277: WILL CONTINUE TO WORK PROPERLY.
278:
279: The only work-around for the problem is to recompile all of
280: the libraries on the system. The easiest way to do this for
1.79 wiz 281: system libraries is to install a binary snapshot; they are
1.93 salo 282: generally available on releng.NetBSD.org. Any packages you
1.75 thorpej 283: have installed which supply libraries will have to be recompiled
284: if you wish to link new programs against those libraries.
285:
286: If you have questions about this matter, please contact
1.93 salo 287: port-arm@NetBSD.org.
1.73 provos 288:
289: 20021011:
290: Systrace has been improved to support privilege elevation.
291: Updating the kernel requires the userland part of systrace
1.79 wiz 292: to be rebuilt.
1.72 thorpej 293:
294: 20021010:
295: The config(8) grammar was changed to allow options to register
296: dependencies on attributes, as well as other options. Users
297: must update and reinstall usr.sbin/config before building a new
298: kernel.
1.70 thorpej 299:
300: 20021009:
301: A new attribute dependency syntax was introduced to config(8),
302: which is now used by the SCSI configuration description. Users
1.71 wiz 303: must update and reinstall usr.sbin/config before building a new
1.70 thorpej 304: kernel.
1.69 thorpej 305:
306: 20021003:
307: Several changes have been made to the autoconfiguration
308: framework. Users must update and reinstall usr.sbin/config
309: before building a new kernel.
1.74 jschauma 310:
311: 20021001:
312: The i386mp branch has been merged. To compile a kernel, users
313: will need to add the option 'cpu* at mainbus?' to their configuration
314: file. Multiprocessor kernels will need
315: ioapic* at mainbus? apid ?
316: options MULTIPROCESSOR
317: options COM_MPLOCK
1.68 lukem 318:
319: 20020922:
320: MKDYNAMICROOT=yes enabled by default, which means that
321: certain shared libraries are installed into /lib, the shared
322: linker is installed into /libexec, and all programs in /bin
323: and /sbin are dynamically linked.
324: If you do not use "make build", you should ensure that
325: you have the libraries and shared linker in the new locations,
326: with:
327: make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so
1.67 lukem 328:
329: 20020917:
330: USE_NEW_TOOLCHAIN has been replaced with:
331: - TOOLCHAIN_MISSING -- set to "yes" on platforms for which
332: there is no working in-tree toolchain (hppa, ns32k, sh5,
333: x86_64).
334: - EXTERNAL_TOOLCHAIN -- if defined by the user, points to the
1.79 wiz 335: root of an external toolchain (e.g. /usr/local/gnu). This
1.67 lukem 336: enables the cross-build framework even for TOOLCHAIN_MISSING
337: platforms.
1.66 gehenna 338:
339: 20020906:
340: gehenna-devsw has been merged into the trunk. Need to update and
1.79 wiz 341: reinstall usr.sbin/config before building the kernel.
1.65 lukem 342:
343: 20020822:
344: Crunched rescue tools (contents of /bin and /sbin, plus others)
345: are now provided in /rescue.
346:
347: To ensure that these are built statically linked (no matter
348: what the setting of LDSTATIC is), use a crunchgen(1) built
349: from sources newer than 20020820 (see the next entry).
350:
351: 20020820:
352: crunchgen(1) changed to ensure that the generated program
353: is statically linked.

387: etc/postinstall added, which performs various checks for
388: configuration file updates and changes, and can fix most of
389: the problems identified.
390: This should make it much easier to upgrade a system's
391: configuration from earlier systems (as far back as NetBSD 1.5).

1.54 itojun 402: 20020311:
403: ssh configuration files were moved from /etc to /etc/ssh. Beware
404: if you restart your machine from remote. Note that sshd.conf needs
405: to be changed (due to the use of "/etc" inside).
406:

425: If you're attempting to build a snapshot on sparc64 and are getting
426: reloc errors from the toolchain groff binary this means your native
427: toolchain has some broken C++ bits.
428:
429: To fix:
430:
431: Build a new toolchain (i.e. build.sh -t)

463: The new document BUILDING.mdoc (view with nroff | more, or
464: see pre-generated .txt and .html versions) describes the build
465: procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
466: build process, are intended in the long run to replace this
467: manual update log.
468:
469: Users building a USE_NEW_TOOLCHAIN system should read the
470: BUILDING document for caveats. Generally, BUILDING supersedes
471: UPDATING for these systems, as tool updating is taken care of
472: by the new build system.

1.64 sommerfe 508: 20010803:
1.41 wiz 509: (i386 only): i386 kernel now uses new instructions like
1.111 simonb 510: `fxsave' which old gas doesn't understand. To build the
1.64 sommerfe 511: kernel successfully, you need to build and install a new toolchain,
512: (i.e., build.sh -t) or (temporarily) comment out "options I686_CPU"
513: from your kernel configuration until you rebuild your userland.
514: See 20011029 above and BUILDING file in this directory for more information.

530: Enabled correct .init/.fini processing in crt0. The way this
531: was done was to change a -I directive to cc(1), which means
532: make(1) will have a stale dependency (it will be checking the
533: timestamp on the wrong "dot_init.h").
534:
535: The symptom you will see is that new programs die with SIGSEGV
536: if you have a stale dependency.

539: before starting your build.
1.26 thorpej 540:

1.1 abs 604:
605:
606: Hints for a more successful build:
607: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 608: Use build.sh, but do not use its "expert mode":
609: This will will automatically build the tools in the
610: correct order, and it will keep the tools and the
611: new build products from interfering with the running
612: system. This will allow you to ignore most of the
613: other advice in this file.
1.2 mrg 614: Build a new kernel first:
615: This makes sure that any new system calls or features
616: expected by the new userland will be present. This
617: helps to avoid critical errors when upgrading.
1.1 abs 618: Use object directories:
619: This helps to keep stale object
620: files from polluting the build if a Makefile "forgets"
621: about one. It also makes it easier to clean up after
622: a build. It's also necessary if you want to use the
623: same source tree for multiple machines.
1.123 jmc 624: To use object directories with build.sh:
625: a) invoke build.sh with the "-M" or "-O" options.
626: To use object directories without using build.sh:
1.1 abs 627: a) cd /usr/src ; make cleandir
1.2 mrg 628: b) Add "OBJMACHINE=yes" to /etc/mk.conf
629: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 630: d) cd /usr/src ; make build
1.2 mrg 631: Note that running "make obj" in a directory will create
632: in obj.$MACHINE directory.
1.1 abs 633: Build to a DESTDIR:
1.123 jmc 634: This helps to keep old installed files (especially libraries)
635: from interfering with the new build.
636: To build to a DESTDIR with build.sh, use the "-D" option.
637: To build to a DESTDIR without using build.sh, set the DESTDIR
638: environment variable before running make build. It should be
639: set to the pathname of an initially empty directory.
640: Problems: if you do not use build.sh, you might need to
641: update critical utilities without using DESTDIR since
642: nothing is executed from what is installed in DESTDIR.
643: (See critical utils, below.)
1.1 abs 644: Build often:
645: This keeps critical utilities current enough to not choke
646: on any other part of the source tree that depends on up to
1.123 jmc 647: date functionality. If you use build.sh, you should not have
648: this problem.
1.1 abs 649:
650: What to do if things don't work:
651: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
652: When things don't work there is usually a few things that commonly
653: should be done.
654: 1) make includes
655: This should be done automatically by make build.
656: 2) cd share/mk && make install
657: Again, automatically done by make build.
658:
659: Failsafe rebuild of a small part of the tree:
660: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
661: To make sure you rebuild something correctly you want to do
662: something like the following:
663: 1) Make sure the includes and .mk files are up to date.
664: 2) Make sure any program used to build the particular
665: utility is up to date. (yacc, lex, etc...)
666: 3) cd ...path/to/util...
667: make cleandir
668: rm ...all obj directories...
669: make cleandir # yes, again
670: make obj
671: make depend && make
672:
673: Failsafe rebuild of the entire tree:
674: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
675: If you really want to make sure the source tree is clean and
1.2 mrg 676: ready for a build try the following. Note that sourcing /etc/mk.conf
677: (a make(1) Makefile) in this manner is not right, and will not work
678: for anyone who uses any make(1) features in /etc/mk.conf.
