9: ^^^^^^^^^^^^^^^
1.99 mrg 10:
1.115 ! christos 11: 20040418:
! 12: Statfs(2) and friends have been replaced with statvfs(2). Before
! 13: installing a newly build userland make sure that you are running
! 14: a newly built kernel with COMPAT_20 set. In addition your libc
! 15: build might not work (undefined SYS_statfs symbol) because make
! 16: clean does not know how to remove files it does not know about
! 17: anymore. Manually remove all objects from the libc build directory.
! 18:
1.114 jmc 19: 20040326:
20: The method by which athhal-elf.o gets pulled into i386 kernel builds
21: has been changed. The file is now stored as a uuencode file in CVS
22: and the generated Makefile will use the new .uue rules from bsd.file.mk
23: to build it.
24:
25: This means you must have the latest bsd.files.mk installed when
26: building a kernel without USETOOLS=yes.
27:
1.113 dan 28: 20040318:
29: A bug in the cgd(4) blowfish code was corrected, without
30: provision of backwards compatibility, after several public
31: notices over several months. Users of cgd with blowfish cipher
32: ONLY must dump their data before updating their kernels, and
33: recreate cgd's and restore data using the new kernel. See
34: (recent message to current-users, URL when mail-index has updated)
35:
1.108 bjh21 36: 20040313:
37: On acorn32, the opms and qms drivers have been withdrawn, and
38: the old wsqms driver is now called qms. Kernel config files
39: will need updating. See the ones in sys/arch/acorn32/conf
40: for examples.
41:
1.106 bjh21 42: 20040125:
43: On acorn32, the beep and sysbeep devices are no longer
44: needed, and will need to be deleted from kernel configuration
45: files.
1.105 bjh21 46:
1.102 dbj 47: 20040109:
48: Compatibility for old ffs superblock layouts has been
49: added, and the restrictive fsck checks have been reenabled
50: when using those layouts. If you have been using -current
51: since 20030402, you may find that fsck again signals fatal
1.110 dbj 52: superblock mismatches. To repair, make sure you have
1.111 simonb 53: an updated fsck_ffs and then you can use fsck_ffs -b 16 -c 4
1.109 dbj 54: to complete the filesystem upgrade. A message has
1.111 simonb 55: been added to the kernel which should detect this problem.
56: See the following discussion for more information:
1.112 keihan 57: http://mail-index.NetBSD.org/current-users/2004/01/11/0022.html
1.102 dbj 58:
1.99 mrg 59: 20031203:
1.100 keihan 60: New binutils builds may fail due to old dependencies.
1.99 mrg 61: It's necessary to "make cleandir" to ensure that
62: the dependencies will be rebuilt correctly.
1.98 wiz 63:
64: 20031111:
65: A newer mkdep is needed. Error noting that is
66: cc: Ambiguous abbreviation --
1.97 lukem 67:
68: 20031008:
69: /usr/include/sys/disklabel_mbr.h was removed.
70: It's necessary to "make cleandir" to ensure that
71: the dependencies will be rebuilt correctly.
1.96 christos 72:
1.109 dbj 73: 20031007:
1.111 simonb 74: A sign exension bug was fixed which set all the high bits
75: of our newly expanded ffs fs_flags. This should only
76: affect users who installed or upgraded in September of 2003.
1.109 dbj 77: A small utility program was posted to tech-kern which
1.111 simonb 78: should fix this problem, and a warning message was added
79: to the kernel which should discover and warn about it. See
80: http://mail-index.NetBSD.org/tech-kern/2003/10/07/0005.html
1.109 dbj 81:
1.96 christos 82: 20030906:
83: With the addition of siginfo support the old signal trampoline
84: code has been deprecated to COMPAT_16. Make sure that your running
85: kernel has COMPAT_16 enabled before building userland.
1.94 christos 86:
87: 20030801:
1.95 wiz 88: With the new openssl, there is some header and library shuffling.
1.94 christos 89: rm -f /usr/include/des.h /usr/include/kerberosIV/* /lib/libdes* \
1.95 wiz 90: /usr/lib/libdes* before building.
1.92 wiz 91:
92: 20030703:
93: Texinfo was updated to 4.6. To avoid failures when trying to
94: build the included texinfo files, do:
95:
96: cd src/gnu/usr.bin/texinfo
97: make MKINFO=no dependall install
1.90 wiz 98:
99: 20030630:
1.101 junyoung 100: Groff was updated to 1.19; it's probably necessary to do
1.91 wiz 101: cd share/mk && make install
1.90 wiz 102: cd src/gnu/usr.bin/groff
103: make MKMAN=no dependall install
104: (untested).
1.89 christos 105:
106: 20030516:
107: Due to bugs in the export handling code, invalid export lines
108: were accepted before and caused the kernel to panic when
109: mountd got restarted because it freed memory that had already
110: been freed. This has been fixed and the kernel checks
111: export addresses very strictly. If you upgrade your kernel,
112: make sure you also upgrade mountd, because if your export
113: file contains lines with an old inet4 address syntax (i.e.
114: a.b.c or a.b or a), they will get rejected by the new kernel.
1.87 bjh21 115:
116: 20030402:
117: The superblock layout for FFS was changed. If you have 1.6
118: fsck binaries, they will signal a fatal superblock mismatch
119: with the first alternate, because they compare too many
120: fields (even ones that aren't useful). If possible, upgrade
121: your fsck_ffs binary before using a new kernel.
122: None of this signals actual filesystem damage.
1.85 atatat 123:
124: 20030324:
125: sendmail version 8.12.8 was imported. Since sendmail is
126: now setgid to the smmsp group, and runs in "collection"
127: mode for most common activities, there is a new config
128: file called submit.cf that needs to live in /etc/mail.
129: The generic submit.cf sample in /usr/share/sendmail/cf
130: is named netbsd-msp.cf. Upgrading your regular sendmail
131: configuration file is also strongly advised.
132:
133: See the section named "MESSAGE SUBMISSION PROGRAM" in
134: the updated /usr/share/sendmail/README file for more
135: information.
1.82 wiz 136:
137: 20030117:
138: Texinfo was updated to 4.3. To avoid failures when trying to
139: build the included texinfo files, do:
140:
141: cd src/gnu/usr.bin/texinfo
142: make MKINFO=no dependall install
1.81 lukem 143:
144: 20021223:
145: The METALOG format changed slightly, to remove the leading
146: "${DESTDIR}" from path names.
147: This only affects people building with UNPRIVED.
148: For complete safety, remove the DESTDIR entirely and
149: update tools/mtree, before running make build.
1.88 itojun 150:
151: 20021219:
152: CVS repository layout was changed. See the following for details
153: if you are using (anonymous) cvs to update your tree.
154:
1.93 salo 155: http://mail-index.NetBSD.org/netbsd-announce/2002/12/19/0000.html
1.80 lukem 156:
157: 20021219:
158: install(1) had a '-N dbdir' option added, to specify an
159: alternate location to look up users & groups (instead
160: of the host system passwd(5) and group(5) databases).
161:
162: The build system was modified to take advantage of
163: this option (using ${NETBSDSRCDIR}/etc), so if you
1.83 kei 164: use USETOOLS==no, you may have to rebuild and
1.80 lukem 165: reinstall usr.bin/xinstall first.
1.78 lukem 166:
167: 20021130:
168: fparseln(3) moved from libutil to libc.
169: If building to DESTDIR=/, reinstall the includes
170: and rebuild libc:
171: make includes
172: make do-lib-libc
173: If using build.sh, "cd tools/compat && make clean"
174: before rebuilding the tools.
1.77 lukem 175:
176: 20021126:
177: The mk.conf(5) variable SYS_INCLUDE has been deprecated,
178: including the optional "SYS_INCLUDE=symlinks" support.
179: All header files, including <sys/*.h> are copied into
180: /usr/include.
1.76 thorpej 181:
182: 20021121:
183: The C run-time support files crtbegin.o and crtend.o
184: (and their companions crtbeginS.o and crtendS.o) were
185: split up, with new crti.o and crtn.o files resulting.
186: This means that libtool needs to be rebuilt once the
187: new libraries are installed. The process of rebuilding
188: libtool will cause it to automatically notice the new
189: required files, but it *must* be rebuilt in order to
190: do this.
191:
192: An out-of-date libtool will result in shared libraries
193: which lack _init() and _fini() routines, which means that
194: their global contructors/destructors will not be invoked.
1.75 thorpej 195:
196: 20021121:
197: A bug related to how ARM ELF objects were tagged has been
198: corrected.
199:
200: NetBSD ARM ELF uses the soft-VFP floating point model by
201: default. However, the assembler lacked support for marking
202: objects as using the VFP floating point format, and the
1.79 wiz 203: compiler was not properly passing the flag indicating "soft-VFP"
1.75 thorpej 204: to the assembler.
205:
206: Unfortunately, this means that the linker will now consider
207: old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be
208: incompatible with new (properly marked) objects.
209:
210: The problem will only manifest itself if you attempt to compile
211: a new program using the fixed toolchain, and link that program
212: against old libraries which do not have the proper "softvfp"
213: markings. ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES
214: WILL CONTINUE TO WORK PROPERLY.
215:
216: The only work-around for the problem is to recompile all of
217: the libraries on the system. The easiest way to do this for
1.79 wiz 218: system libraries is to install a binary snapshot; they are
1.93 salo 219: generally available on releng.NetBSD.org. Any packages you
1.75 thorpej 220: have installed which supply libraries will have to be recompiled
221: if you wish to link new programs against those libraries.
222:
223: If you have questions about this matter, please contact
1.93 salo 224: port-arm@NetBSD.org.
1.73 provos 225:
226: 20021011:
227: Systrace has been improved to support privilege elevation.
228: Updating the kernel requires the userland part of systrace
1.79 wiz 229: to be rebuilt.
1.72 thorpej 230:
231: 20021010:
232: The config(8) grammar was changed to allow options to register
233: dependencies on attributes, as well as other options. Users
234: must update and reinstall usr.sbin/config before building a new
235: kernel.
1.70 thorpej 236:
237: 20021009:
238: A new attribute dependency syntax was introduced to config(8),
239: which is now used by the SCSI configuration description. Users
1.71 wiz 240: must update and reinstall usr.sbin/config before building a new
1.70 thorpej 241: kernel.
1.69 thorpej 242:
243: 20021003:
244: Several changes have been made to the autoconfiguration
245: framework. Users must update and reinstall usr.sbin/config
246: before building a new kernel.
1.74 jschauma 247:
248: 20021001:
249: The i386mp branch has been merged. To compile a kernel, users
250: will need to add the option 'cpu* at mainbus?' to their configuration
251: file. Multiprocessor kernels will need
252: ioapic* at mainbus? apid ?
253: options MULTIPROCESSOR
254: options COM_MPLOCK
1.68 lukem 255:
256: 20020922:
257: MKDYNAMICROOT=yes enabled by default, which means that
258: certain shared libraries are installed into /lib, the shared
259: linker is installed into /libexec, and all programs in /bin
260: and /sbin are dynamically linked.
261: If you do not use "make build", you should ensure that
262: you have the libraries and shared linker in the new locations,
263: with:
264: make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so
1.67 lukem 265:
266: 20020917:
267: USE_NEW_TOOLCHAIN has been replaced with:
268: - TOOLCHAIN_MISSING -- set to "yes" on platforms for which
269: there is no working in-tree toolchain (hppa, ns32k, sh5,
270: x86_64).
271: - EXTERNAL_TOOLCHAIN -- if defined by the user, points to the
1.79 wiz 272: root of an external toolchain (e.g. /usr/local/gnu). This
1.67 lukem 273: enables the cross-build framework even for TOOLCHAIN_MISSING
274: platforms.
1.66 gehenna 275:
276: 20020906:
277: gehenna-devsw has been merged into the trunk. Need to update and
1.79 wiz 278: reinstall usr.sbin/config before building the kernel.
1.65 lukem 279:
280: 20020822:
281: Crunched rescue tools (contents of /bin and /sbin, plus others)
282: are now provided in /rescue.
283:
284: To ensure that these are built statically linked (no matter
285: what the setting of LDSTATIC is), use a crunchgen(1) built
286: from sources newer than 20020820 (see the next entry).
287:
288: 20020820:
289: crunchgen(1) changed to ensure that the generated program
290: is statically linked.
291:
292: Solution: update and reinstall usr.bin/crunch
1.84 grant 293:
294: 20020605:
295: smmsp user/group has been added for sendmail.
296:
297: Add the following into /etc/group:
298:
299: smmsp:*:17:
300:
301: and the following to /etc/master.passwd (via vipw):
302:
303: smmsp:*:17:17::0:0:Sendmail Message Submission Program:/nonexistent:/sbin/nologin
1.61 itojun 304:
305: 20020515:
306: sshd user/group has been added. Need to hand add this in, or sshd
307: will not let you log in (with default, or UsePrivlegeSeparation=yes)
308:
309: Add the following into /etc/group:
310:
311: sshd:*:16:
312:
313: and the following to /etc/master.passwd (via vipw):
314:
1.63 enami 315: sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin
1.61 itojun 316:
1.79 wiz 317: Also /var/chroot/sshd directory needs to be present (digged as part of
318: the build process).
1.60 sommerfe 319:
320: 20020426:
321: NBUILDJOBS obsoleted in favor of just using -j.
1.59 lukem 322:
323: 20020426:
324: etc/postinstall added, which performs various checks for
325: configuration file updates and changes, and can fix most of
326: the problems identified.
327: This should make it much easier to upgrade a system's
328: configuration from earlier systems (as far back as NetBSD 1.5).
1.56 lukem 329:
330: 20020320:
1.79 wiz 331: <bsd.lib.mk> needs a new install(1) for its "-a cmd" support.
332: Build and install at usr.bin/xinstall before the build.
1.56 lukem 333:
1.55 itojun 334: 20020319:
1.79 wiz 335: Raw IPv6 socket now makes strict checking for sa_family and sa_len
336: on send(2) operation. Be sure to have sbin/rtsol and usr.sbin/rtsold
1.55 itojun 337: newer than November 2001 when you upgrade the kernel.
338:
1.54 itojun 339: 20020311:
340: ssh configuration files were moved from /etc to /etc/ssh. Beware
341: if you restart your machine from remote. Note that sshd.conf needs
342: to be changed (due to the use of "/etc" inside).
343:
344: 20020223:
1.53 matt 345: Users of the VAX port will need to rebuild and install gas
346: so it deal with the now present register prefix used in all
347: the VAX assembly files.
348:
1.50 itojun 349: 20020118:
350: ntpd user/group has been added. Need to hand add this in or builds
351: will break as mtree aborts early.
352:
353: Add the following into /etc/group:
354:
355: ntpd:*:15:
356:
357: and the following to /etc/master.passwd (via vipw):
358:
359: ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin
360:
1.49 jmc 361: 20011207:
362: If you're attempting to build a snapshot on sparc64 and are getting
363: reloc errors from the toolchain groff binary this means your native
364: toolchain has some broken C++ bits.
365:
366: To fix:
367:
368: Build a new toolchain (i.e. build.sh -t)
369: Use the new toolchain to build and install natively (i.e. /usr/lib)
370:
371: gnu/lib/libgcc
1.51 pooka 372: gnu/lib/libstdc++
1.49 jmc 373:
374: After this a snapshot will be able to be built.
375:
1.47 jmc 376: 20011201:
377: In order for a sparc64 build to work you must have a working awk. If
378: you've built and installed a system with the new toolchain up to this
1.52 wiz 379: point you do not have a working awk as its ability to do floating
1.47 jmc 380: point is broken.
381:
382: To build:
383:
384: remake and install gnu/lib/libgcc
385: remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links
1.48 jmc 386: against the new libgcc.a)
1.47 jmc 387:
1.46 thorpej 388: 20011128:
389: Kernel config information was changed to use defflag in
390: the various "files" files. Bug fixes to config(8) are
391: required in order for this to work properly. Make sure
392: to build and install in usr.sbin/config before attempting
393: to build a new kernel.
394:
1.45 yamt 395: 20011030:
396: libc/locale/wcstod.c now needs new lint(1). Update lint(1)
397: before building libc.
1.43 mason 398:
1.44 tv 399: 20011029:
400: The new document BUILDING.mdoc (view with nroff | more, or
401: see pre-generated .txt and .html versions) describes the build
402: procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
403: build process, are intended in the long run to replace this
404: manual update log.
405:
406: Users building a USE_NEW_TOOLCHAIN system should read the
407: BUILDING document for caveats. Generally, BUILDING supersedes
408: UPDATING for these systems, as tool updating is taken care of
409: by the new build system.
1.42 perry 410:
411: 20011028:
412: src/etc/Makefile now needs install to be able to handle
413: symlinks that point to nowhere. A bug in install that
414: prevented this was corrected.
415:
416: Solution: update and reinstall usr.bin/xinstall
417: Better Solution: Use the new toolchain and it will just work
418: for you.
1.40 lukem 419:
420: 20011006:
421: /etc/mtree/NetBSD.dist has been updated to take advantage of
422: absolute path support added to mtree(8). Older mtree(8)s don't
423: understand the format.
424:
425: Solution: update and reinstall usr.sbin/mtree
1.39 jmc 426:
427: 20011004:
428: Crunchgen has been updated to work via reach-over makefiles. Updating
429: is suggested before running a snapshot build
1.36 tv 430:
1.35 thorpej 431: 20010915:
432: The new "ubcperf" code committed by Chuck Silvers removed
433: a header file, uvm/uvm_vnode.h. There may be stale .depend
434: files that still reference this file.
435:
436: Solution: "make cleandir && make dependall" in affected
437: directories.
1.31 enami 438:
439: 20010803:
440: grep.info is now built from grep.texi using makeinfo. Since it
441: requires makeinfo v4.0, you need to install new texinfo before
442: building gnu/usr.bin/grep. To install new texinfo, please follow
443: the instruction described in 20010726 entry.
1.30 enami 444:
1.64 sommerfe 445: 20010803:
1.41 wiz 446: (i386 only): i386 kernel now uses new instructions like
1.111 simonb 447: `fxsave' which old gas doesn't understand. To build the
1.64 sommerfe 448: kernel successfully, you need to build and install a new toolchain,
449: (i.e., build.sh -t) or (temporarily) comment out "options I686_CPU"
450: from your kernel configuration until you rebuild your userland.

467: Enabled correct .init/.fini processing in crt0. The way this
468: was done was to change a -I directive to cc(1), which means
469: make(1) will have a stale dependency (it will be checking the
470: timestamp on the wrong "dot_init.h").
471:
472: The symptom you will see is that new programs die with SIGSEGV
473: if you have a stale dependency.
474:
475: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
476: before starting your build.
1.26 thorpej 477:
478: 20010628:
479: A construct was added to uvm_page.h that uncovered a bug
480: in lint(1). If you get a warning/error about a non-portable
481: bitfield, update your lint(1) before proceeding.

1.18 jmc 498:

1.52 wiz 500: get/setprogname() added. Any hostprogs that may use this will need
1.111 simonb 501: to be bootstrapped manually until the host system is current.
1.18 jmc 502:
1.111 simonb 503: Known problems: sys/arch/macppc/stand/fixcoff
1.19 cgd 504: usr.sbin/config (adding -DMAKE_BOOTSTRAP to

1.15 christos 508:
509: 20010204:
510: prepare the code to compile with stricter gcc flags. in
511: particular start eliminating redundant declarations. Yacc
512: needs to be installed before make build.
1.10 christos 513:
514: 20010114:
515: introduce .if commands(target) in make(1). You need to
516: bring everything up-to-date first, then without installing
1.23 tron 517: anything make and install in usr.bin/make, then proceed
1.10 christos 518: with make build.
1.9 sommerfe 519:

521: bsd.subdir.mk committed 20001230 had a bug which caused
522: afterinstall targets to run too soon; update again.
1.8 sommerfe 523:
524: 20001230:
525: New share/mk files needed to support .WAIT in SUBDIR variables.
526: If you get make errors,
527: (cd share/mk; make install)
528: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 529:
530: 20001019:
1.7 ad 531: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 532: major and minor numbers haven't changed, you should update your /dev
533: directory.
1.1 abs 534:
1.4 itojun 535: 20000929:
536: The following make directives are obsoleted.
537: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
538: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 539: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 540: additional library libcrypto_{idea,rc5}.
1.1 abs 541:
542:
543: Hints for a more successful build:
544: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 545: Build a new kernel first:
546: This makes sure that any new system calls or features
547: expected by the new userland will be present. This
548: helps to avoid critical errors when upgrading.
1.1 abs 549: Use object directories:
550: This helps to keep stale object
551: files from polluting the build if a Makefile "forgets"
552: about one. It also makes it easier to clean up after
553: a build. It's also necessary if you want to use the
554: same source tree for multiple machines.
555: To use object directories:
556: a) cd /usr/src ; make cleandir
1.2 mrg 557: b) Add "OBJMACHINE=yes" to /etc/mk.conf
558: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 559: d) cd /usr/src ; make build
1.2 mrg 560: Note that running "make obj" in a directory will create
561: in obj.$MACHINE directory.
1.1 abs 562: Build to a DESTDIR:
563: This helps to keep old
564: installed files (especially libraries) from interfering
565: with the new build.
566: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 567: variable before running make build. It should be set to
568: the pathname of an initially empty directory.
1.1 abs 569: Problems: you might need to update critical utilities
570: without using DESTDIR since nothing is executed
571: from what is installed in DESTDIR.
572: (See critical utils, below)
573: Build often:
574: This keeps critical utilities current enough to not choke
575: on any other part of the source tree that depends on up to
576: date functionality.
577:
578: What to do if things don't work:
579: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
580: When things don't work there is usually a few things that commonly
581: should be done.
582: 1) make includes
583: This should be done automatically by make build.
584: 2) cd share/mk && make install
585: Again, automatically done by make build.
586:
587: Failsafe rebuild of a small part of the tree:
588: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
589: To make sure you rebuild something correctly you want to do
590: something like the following:
591: 1) Make sure the includes and .mk files are up to date.
592: 2) Make sure any program used to build the particular
593: utility is up to date. (yacc, lex, etc...)
594: 3) cd ...path/to/util...
595: make cleandir
596: rm ...all obj directories...
597: make cleandir # yes, again
598: make obj
599: make depend && make
600:
601: Failsafe rebuild of the entire tree:
602: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
603: If you really want to make sure the source tree is clean and
1.2 mrg 604: ready for a build try the following. Note that sourcing /etc/mk.conf
605: (a make(1) Makefile) in this manner is not right, and will not work
606: for anyone who uses any make(1) features in /etc/mk.conf.
