1.119 ! atatat 11: 20040426:
! 12: Support for the original dynamic sysctl node structure has
! 13: been removed in favor of the newer layout. This affects
! 14: consumers of the create and delete interface, as well as
! 15: the dynamic discovery mechanism. This is believed only to
! 16: be the sysctl(8) binary itself, at this point in time, so
! 17: the only effect of this should be that a sysctl binary
! 18: built from sources dated between 2003/12/04 and 2004/03/24
! 19: will not work on a kernel built from sources dated after
! 20: 2004/04/25. If you need a new sysctl binary but build.sh
! 21: does not work, make sure that your revision of
! 22: /usr/include/sys/sysctl.h is 1.112 (or later), and then
! 23: the following should provide a functioning sysctl binary:
! 24:
! 25: cd src/sbin/sysctl
! 26: make USETOOLS=no dependall install
! 27:
1.118 dbj 28: 20040425:
29: The ffs superblock issues listed below under 20040109 and 20030402
30: are now automatically addressed by the /etc/rc.d/fixsb script or by
31: sysinst when it checks a a filesystem. The manual fsck_ffs -b16 -c4
32: invocation mentioned below will continue to work and is now
33: automated by those scripts. Note that under certain circumstances,
34: affected filesystems upgraded to a -current kernel first before
35: upgrading their userland with the fixsb and fsck_ffs fixes may
36: encounter a 'freeing free inode' panic when writing to the affected
37: filesystem, so it is a good idea to repair the filesystem as soon as
38: possible. For more details on the fixsb script, see pr install/25138.
39:
1.115 christos 40: 20040418:
41: Statfs(2) and friends have been replaced with statvfs(2). Before
42: installing a newly build userland make sure that you are running
43: a newly built kernel with COMPAT_20 set. In addition your libc
44: build might not work (undefined SYS_statfs symbol) because make
45: clean does not know how to remove files it does not know about
1.116 christos 46: anymore. Manually remove all generated .S sources and objects
47: from the libc build directory.
1.115 christos 48:
1.114 jmc 49: 20040326:
50: The method by which athhal-elf.o gets pulled into i386 kernel builds
1.117 jmc 51: has been changed. The file is now stored as a uuencoded file in CVS
1.114 jmc 52: and the generated Makefile will use the new .uue rules from bsd.file.mk
53: to build it.
54:
55: This means you must have the latest bsd.files.mk installed when
56: building a kernel without USETOOLS=yes.
57:
1.113 dan 58: 20040318:
59: A bug in the cgd(4) blowfish code was corrected, without
60: provision of backwards compatibility, after several public
61: notices over several months. Users of cgd with blowfish cipher
62: ONLY must dump their data before updating their kernels, and
63: recreate cgd's and restore data using the new kernel. See
64: (recent message to current-users, URL when mail-index has updated)
65:
1.108 bjh21 66: 20040313:
67: On acorn32, the opms and qms drivers have been withdrawn, and
68: the old wsqms driver is now called qms. Kernel config files
69: will need updating. See the ones in sys/arch/acorn32/conf
70: for examples.
71:
1.106 bjh21 72: 20040125:
73: On acorn32, the beep and sysbeep devices are no longer
74: needed, and will need to be deleted from kernel configuration
75: files.
1.105 bjh21 76:
1.102 dbj 77: 20040109:
78: Compatibility for old ffs superblock layouts has been
79: added, and the restrictive fsck checks have been reenabled
80: when using those layouts. If you have been using -current
81: since 20030402, you may find that fsck again signals fatal
1.110 dbj 82: superblock mismatches. To repair, make sure you have
1.111 simonb 83: an updated fsck_ffs and then you can use fsck_ffs -b 16 -c 4
1.109 dbj 84: to complete the filesystem upgrade. A message has
1.111 simonb 85: been added to the kernel which should detect this problem.
86: See the following discussion for more information:
1.112 keihan 87: http://mail-index.NetBSD.org/current-users/2004/01/11/0022.html
1.102 dbj 88:
1.99 mrg 89: 20031203:
1.100 keihan 90: New binutils builds may fail due to old dependencies.
1.99 mrg 91: It's necessary to "make cleandir" to ensure that
92: the dependencies will be rebuilt correctly.
1.98 wiz 93:
94: 20031111:
95: A newer mkdep is needed. Error noting that is
96: cc: Ambiguous abbreviation --
1.97 lukem 97:

99: /usr/include/sys/disklabel_mbr.h was removed.
100: It's necessary to "make cleandir" to ensure that
101: the dependencies will be rebuilt correctly.
1.96 christos 102:
1.109 dbj 103: 20031007:
1.111 simonb 104: A sign exension bug was fixed which set all the high bits
105: of our newly expanded ffs fs_flags. This should only
106: affect users who installed or upgraded in September of 2003.
1.109 dbj 107: A small utility program was posted to tech-kern which
1.111 simonb 108: should fix this problem, and a warning message was added
109: to the kernel which should discover and warn about it. See
110: http://mail-index.NetBSD.org/tech-kern/2003/10/07/0005.html
1.109 dbj 111:
1.96 christos 112: 20030906:
113: With the addition of siginfo support the old signal trampoline
114: code has been deprecated to COMPAT_16. Make sure that your running
115: kernel has COMPAT_16 enabled before building userland.
1.94 christos 116:
117: 20030801:
1.95 wiz 118: With the new openssl, there is some header and library shuffling.
1.94 christos 119: rm -f /usr/include/des.h /usr/include/kerberosIV/* /lib/libdes* \
1.95 wiz 120: /usr/lib/libdes* before building.
1.92 wiz 121:
122: 20030703:
123: Texinfo was updated to 4.6. To avoid failures when trying to
124: build the included texinfo files, do:
125:
126: cd src/gnu/usr.bin/texinfo
127: make MKINFO=no dependall install
1.90 wiz 128:
129: 20030630:
1.101 junyoung 130: Groff was updated to 1.19; it's probably necessary to do
1.91 wiz 131: cd share/mk && make install
1.90 wiz 132: cd src/gnu/usr.bin/groff
133: make MKMAN=no dependall install
134: (untested).
1.89 christos 135:
136: 20030516:
137: Due to bugs in the export handling code, invalid export lines
138: were accepted before and caused the kernel to panic when
139: mountd got restarted because it freed memory that had already
140: been freed. This has been fixed and the kernel checks
141: export addresses very strictly. If you upgrade your kernel,
142: make sure you also upgrade mountd, because if your export
143: file contains lines with an old inet4 address syntax (i.e.
144: a.b.c or a.b or a), they will get rejected by the new kernel.
1.87 bjh21 145:
146: 20030402:
147: The superblock layout for FFS was changed. If you have 1.6
148: fsck binaries, they will signal a fatal superblock mismatch
149: with the first alternate, because they compare too many
150: fields (even ones that aren't useful). If possible, upgrade
151: your fsck_ffs binary before using a new kernel.
152: None of this signals actual filesystem damage.
1.85 atatat 153:
154: 20030324:
155: sendmail version 8.12.8 was imported. Since sendmail is
156: now setgid to the smmsp group, and runs in "collection"
157: mode for most common activities, there is a new config
158: file called submit.cf that needs to live in /etc/mail.
159: The generic submit.cf sample in /usr/share/sendmail/cf
160: is named netbsd-msp.cf. Upgrading your regular sendmail
161: configuration file is also strongly advised.
162:
163: See the section named "MESSAGE SUBMISSION PROGRAM" in
164: the updated /usr/share/sendmail/README file for more
165: information.
1.82 wiz 166:
167: 20030117:
168: Texinfo was updated to 4.3. To avoid failures when trying to
169: build the included texinfo files, do:
170:
171: cd src/gnu/usr.bin/texinfo
172: make MKINFO=no dependall install
1.81 lukem 173:
174: 20021223:
175: The METALOG format changed slightly, to remove the leading
176: "${DESTDIR}" from path names.
177: This only affects people building with UNPRIVED.
178: For complete safety, remove the DESTDIR entirely and
179: update tools/mtree, before running make build.
1.88 itojun 180:
181: 20021219:
182: CVS repository layout was changed. See the following for details
183: if you are using (anonymous) cvs to update your tree.
184:
1.93 salo 185: http://mail-index.NetBSD.org/netbsd-announce/2002/12/19/0000.html
1.80 lukem 186:
187: 20021219:
188: install(1) had a '-N dbdir' option added, to specify an
189: alternate location to look up users & groups (instead
190: of the host system passwd(5) and group(5) databases).
191:
192: The build system was modified to take advantage of
193: this option (using ${NETBSDSRCDIR}/etc), so if you
1.83 kei 194: use USETOOLS==no, you may have to rebuild and
1.80 lukem 195: reinstall usr.bin/xinstall first.
1.78 lukem 196:
197: 20021130:
198: fparseln(3) moved from libutil to libc.
199: If building to DESTDIR=/, reinstall the includes
200: and rebuild libc:
201: make includes
202: make do-lib-libc
203: If using build.sh, "cd tools/compat && make clean"
204: before rebuilding the tools.
1.77 lukem 205:
206: 20021126:
207: The mk.conf(5) variable SYS_INCLUDE has been deprecated,
208: including the optional "SYS_INCLUDE=symlinks" support.
209: All header files, including <sys/*.h> are copied into
210: /usr/include.
1.76 thorpej 211:
212: 20021121:
213: The C run-time support files crtbegin.o and crtend.o
214: (and their companions crtbeginS.o and crtendS.o) were
215: split up, with new crti.o and crtn.o files resulting.
216: This means that libtool needs to be rebuilt once the
217: new libraries are installed. The process of rebuilding
218: libtool will cause it to automatically notice the new
219: required files, but it *must* be rebuilt in order to
220: do this.
221:
222: An out-of-date libtool will result in shared libraries
223: which lack _init() and _fini() routines, which means that
224: their global contructors/destructors will not be invoked.
1.75 thorpej 225:
226: 20021121:
227: A bug related to how ARM ELF objects were tagged has been
228: corrected.
229:
230: NetBSD ARM ELF uses the soft-VFP floating point model by
231: default. However, the assembler lacked support for marking
232: objects as using the VFP floating point format, and the
1.79 wiz 233: compiler was not properly passing the flag indicating "soft-VFP"
1.75 thorpej 234: to the assembler.
235:
236: Unfortunately, this means that the linker will now consider
237: old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be
238: incompatible with new (properly marked) objects.
239:
240: The problem will only manifest itself if you attempt to compile
241: a new program using the fixed toolchain, and link that program
242: against old libraries which do not have the proper "softvfp"
243: markings. ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES
244: WILL CONTINUE TO WORK PROPERLY.
245:
246: The only work-around for the problem is to recompile all of
247: the libraries on the system. The easiest way to do this for
1.79 wiz 248: system libraries is to install a binary snapshot; they are
1.93 salo 249: generally available on releng.NetBSD.org. Any packages you
1.75 thorpej 250: have installed which supply libraries will have to be recompiled
251: if you wish to link new programs against those libraries.
252:
253: If you have questions about this matter, please contact
1.93 salo 254: port-arm@NetBSD.org.
1.73 provos 255:
256: 20021011:
257: Systrace has been improved to support privilege elevation.
258: Updating the kernel requires the userland part of systrace
1.79 wiz 259: to be rebuilt.
1.72 thorpej 260:
261: 20021010:
262: The config(8) grammar was changed to allow options to register
263: dependencies on attributes, as well as other options. Users
264: must update and reinstall usr.sbin/config before building a new
265: kernel.
1.70 thorpej 266:
267: 20021009:
268: A new attribute dependency syntax was introduced to config(8),
269: which is now used by the SCSI configuration description. Users
1.71 wiz 270: must update and reinstall usr.sbin/config before building a new
1.70 thorpej 271: kernel.
1.69 thorpej 272:
273: 20021003:
274: Several changes have been made to the autoconfiguration
275: framework. Users must update and reinstall usr.sbin/config
276: before building a new kernel.
1.74 jschauma 277:
278: 20021001:
279: The i386mp branch has been merged. To compile a kernel, users
280: will need to add the option 'cpu* at mainbus?' to their configuration
281: file. Multiprocessor kernels will need
282: ioapic* at mainbus? apid ?
283: options MULTIPROCESSOR
284: options COM_MPLOCK
1.68 lukem 285:
286: 20020922:
287: MKDYNAMICROOT=yes enabled by default, which means that
288: certain shared libraries are installed into /lib, the shared
289: linker is installed into /libexec, and all programs in /bin
290: and /sbin are dynamically linked.
291: If you do not use "make build", you should ensure that
292: you have the libraries and shared linker in the new locations,
293: with:
294: make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so
1.67 lukem 295:
296: 20020917:
297: USE_NEW_TOOLCHAIN has been replaced with:
298: - TOOLCHAIN_MISSING -- set to "yes" on platforms for which
299: there is no working in-tree toolchain (hppa, ns32k, sh5,
300: x86_64).
301: - EXTERNAL_TOOLCHAIN -- if defined by the user, points to the
1.79 wiz 302: root of an external toolchain (e.g. /usr/local/gnu). This
1.67 lukem 303: enables the cross-build framework even for TOOLCHAIN_MISSING
304: platforms.
1.66 gehenna 305:
306: 20020906:
307: gehenna-devsw has been merged into the trunk. Need to update and
1.79 wiz 308: reinstall usr.sbin/config before building the kernel.
1.65 lukem 309:
310: 20020822:
311: Crunched rescue tools (contents of /bin and /sbin, plus others)
312: are now provided in /rescue.
313:
314: To ensure that these are built statically linked (no matter
315: what the setting of LDSTATIC is), use a crunchgen(1) built
316: from sources newer than 20020820 (see the next entry).
317:
318: 20020820:
319: crunchgen(1) changed to ensure that the generated program
320: is statically linked.
321:
322: Solution: update and reinstall usr.bin/crunch

348: the build process).
1.60 sommerfe 349:

351: NBUILDJOBS obsoleted in favor of just using -j.
1.59 lukem 352:
353: 20020426:
354: etc/postinstall added, which performs various checks for
355: configuration file updates and changes, and can fix most of
356: the problems identified.
357: This should make it much easier to upgrade a system's
358: configuration from earlier systems (as far back as NetBSD 1.5).

366: on send(2) operation. Be sure to have sbin/rtsol and usr.sbin/rtsold
1.55 itojun 367: newer than November 2001 when you upgrade the kernel.
368:
1.54 itojun 369: 20020311:
370: ssh configuration files were moved from /etc to /etc/ssh. Beware
371: if you restart your machine from remote. Note that sshd.conf needs
372: to be changed (due to the use of "/etc" inside).
373:

392: If you're attempting to build a snapshot on sparc64 and are getting
393: reloc errors from the toolchain groff binary this means your native
394: toolchain has some broken C++ bits.
395:
396: To fix:
397:
398: Build a new toolchain (i.e. build.sh -t)
399: Use the new toolchain to build and install natively (i.e. /usr/lib)
400:
401: gnu/lib/libgcc
1.51 pooka 402: gnu/lib/libstdc++
1.49 jmc 403:
404: After this a snapshot will be able to be built.
405:
1.47 jmc 406: 20011201:
407: In order for a sparc64 build to work you must have a working awk. If
408: you've built and installed a system with the new toolchain up to this
1.52 wiz 409: point you do not have a working awk as its ability to do floating
1.47 jmc 410: point is broken.
411:
412: To build:
413:
414: remake and install gnu/lib/libgcc
415: remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links
1.48 jmc 416: against the new libgcc.a)
1.47 jmc 417:
1.46 thorpej 418: 20011128:
419: Kernel config information was changed to use defflag in
420: the various "files" files. Bug fixes to config(8) are
421: required in order for this to work properly. Make sure
422: to build and install in usr.sbin/config before attempting
423: to build a new kernel.

1.44 tv 429: 20011029:
430: The new document BUILDING.mdoc (view with nroff | more, or
431: see pre-generated .txt and .html versions) describes the build
432: procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
433: build process, are intended in the long run to replace this
434: manual update log.
435:
436: Users building a USE_NEW_TOOLCHAIN system should read the
437: BUILDING document for caveats. Generally, BUILDING supersedes
438: UPDATING for these systems, as tool updating is taken care of
439: by the new build system.
1.42 perry 440:
441: 20011028:
442: src/etc/Makefile now needs install to be able to handle
443: symlinks that point to nowhere. A bug in install that
444: prevented this was corrected.
445:
446: Solution: update and reinstall usr.bin/xinstall
447: Better Solution: Use the new toolchain and it will just work
448: for you.

451: /etc/mtree/NetBSD.dist has been updated to take advantage of
452: absolute path support added to mtree(8). Older mtree(8)s don't
453: understand the format.
454:
455: Solution: update and reinstall usr.sbin/mtree
1.39 jmc 456:

458: Crunchgen has been updated to work via reach-over makefiles. Updating
459: is suggested before running a snapshot build
1.36 tv 460:
1.35 thorpej 461: 20010915:
462: The new "ubcperf" code committed by Chuck Silvers removed
463: a header file, uvm/uvm_vnode.h. There may be stale .depend
464: files that still reference this file.
465:
466: Solution: "make cleandir && make dependall" in affected
467: directories.
1.31 enami 468:
469: 20010803:
470: grep.info is now built from grep.texi using makeinfo. Since it
471: requires makeinfo v4.0, you need to install new texinfo before
472: building gnu/usr.bin/grep. To install new texinfo, please follow
473: the instruction described in 20010726 entry.
1.30 enami 474:
1.64 sommerfe 475: 20010803:
1.41 wiz 476: (i386 only): i386 kernel now uses new instructions like
1.111 simonb 477: `fxsave' which old gas doesn't understand. To build the
1.64 sommerfe 478: kernel successfully, you need to build and install a new toolchain,
479: (i.e., build.sh -t) or (temporarily) comment out "options I686_CPU"
480: from your kernel configuration until you rebuild your userland.
481: See 20011029 above and BUILDING file in this directory for more information.
482: [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]
1.29 bjh21 483:
484: 20010731:
485: Bootloader update on ELF platforms. DDB in kernels from before
486: this will be unable to read symbol tables provided by newer
487: bootloaders.
1.27 assar 488:
489: 20010726:
490: Texinfo was updated to 4.0. To avoid failures when trying to
1.28 assar 491: build the included texinfo files, do:
492:
493: cd src/gnu/usr.bin/texinfo
494: make MKINFO=no dependall install
1.25 thorpej 495:
496: 20010718:
497: Enabled correct .init/.fini processing in crt0. The way this
498: was done was to change a -I directive to cc(1), which means
499: make(1) will have a stale dependency (it will be checking the
500: timestamp on the wrong "dot_init.h").
501:
502: The symptom you will see is that new programs die with SIGSEGV
503: if you have a stale dependency.
504:
505: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
506: before starting your build.
1.26 thorpej 507:
508: 20010628:
509: A construct was added to uvm_page.h that uncovered a bug
510: in lint(1). If you get a warning/error about a non-portable
511: bitfield, update your lint(1) before proceeding.
1.21 jmc 512:
513: 20010226:
1.22 jmc 514: Added named user/group to system. Need to hand add this in or builds
1.21 jmc 515: will break as mtree aborts early.
516:
517: To work around add by hand:
518:
519: named:*:14:
520:
1.22 jmc 521: to /etc/group and add:
522:
523: named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin
524:
525: to master.passwd (use vipw for instance if doing by hand).
526:
527: Now a make build should progress.
1.18 jmc 528:
529: 20010219:
1.52 wiz 530: get/setprogname() added. Any hostprogs that may use this will need
1.111 simonb 531: to be bootstrapped manually until the host system is current.
1.18 jmc 532:
1.111 simonb 533: Known problems: sys/arch/macppc/stand/fixcoff
1.19 cgd 534: usr.sbin/config (adding -DMAKE_BOOTSTRAP to
535: CFLAGS and rebuilding should work)
1.20 jmc 536: usr.sbin/mdsetimage - Build a static copy if
1.111 simonb 537: building a snapshot before fully bootstrapped.
1.15 christos 538:
539: 20010204:
540: prepare the code to compile with stricter gcc flags. in
541: particular start eliminating redundant declarations. Yacc
542: needs to be installed before make build.
1.10 christos 543:
544: 20010114:
545: introduce .if commands(target) in make(1). You need to
546: bring everything up-to-date first, then without installing
1.23 tron 547: anything make and install in usr.bin/make, then proceed
1.10 christos 548: with make build.
1.9 sommerfe 549:
550: 20010101:
551: bsd.subdir.mk committed 20001230 had a bug which caused
552: afterinstall targets to run too soon; update again.
1.8 sommerfe 553:
554: 20001230:
555: New share/mk files needed to support .WAIT in SUBDIR variables.
556: If you get make errors,
557: (cd share/mk; make install)
558: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 559:
560: 20001019:
1.7 ad 561: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 562: major and minor numbers haven't changed, you should update your /dev
563: directory.
1.1 abs 564:
1.4 itojun 565: 20000929:
566: The following make directives are obsoleted.
567: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
568: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 569: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 570: additional library libcrypto_{idea,rc5}.
1.1 abs 571:
572:
573: Hints for a more successful build:
574: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 575: Build a new kernel first:
576: This makes sure that any new system calls or features
577: expected by the new userland will be present. This
578: helps to avoid critical errors when upgrading.
1.1 abs 579: Use object directories:
580: This helps to keep stale object
581: files from polluting the build if a Makefile "forgets"
582: about one. It also makes it easier to clean up after
583: a build. It's also necessary if you want to use the
584: same source tree for multiple machines.
585: To use object directories:
586: a) cd /usr/src ; make cleandir
1.2 mrg 587: b) Add "OBJMACHINE=yes" to /etc/mk.conf
588: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 589: d) cd /usr/src ; make build
1.2 mrg 590: Note that running "make obj" in a directory will create
591: in obj.$MACHINE directory.
1.1 abs 592: Build to a DESTDIR:
593: This helps to keep old
594: installed files (especially libraries) from interfering
595: with the new build.
596: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 597: variable before running make build. It should be set to
598: the pathname of an initially empty directory.
1.1 abs 599: Problems: you might need to update critical utilities
600: without using DESTDIR since nothing is executed
601: from what is installed in DESTDIR.
602: (See critical utils, below)
603: Build often:
604: This keeps critical utilities current enough to not choke
605: on any other part of the source tree that depends on up to
606: date functionality.
607:
608: What to do if things don't work:
609: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
610: When things don't work there is usually a few things that commonly
611: should be done.
612: 1) make includes
613: This should be done automatically by make build.
614: 2) cd share/mk && make install
615: Again, automatically done by make build.
616:
617: Failsafe rebuild of a small part of the tree:
618: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
619: To make sure you rebuild something correctly you want to do
620: something like the following:
621: 1) Make sure the includes and .mk files are up to date.
622: 2) Make sure any program used to build the particular
623: utility is up to date. (yacc, lex, etc...)
624: 3) cd ...path/to/util...
625: make cleandir
626: rm ...all obj directories...
627: make cleandir # yes, again
628: make obj
629: make depend && make
630:
631: Failsafe rebuild of the entire tree:
632: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
633: If you really want to make sure the source tree is clean and
1.2 mrg 634: ready for a build try the following. Note that sourcing /etc/mk.conf
635: (a make(1) Makefile) in this manner is not right, and will not work
636: for anyone who uses any make(1) features in /etc/mk.conf.
