9: ^^^^^^^^^^^^^^^
1.87 ! bjh21 10:
! 11: 20030402:
! 12: The superblock layout for FFS was changed. If you have 1.6
! 13: fsck binaries, they will signal a fatal superblock mismatch
! 14: with the first alternate, because they compare too many
! 15: fields (even ones that aren't useful). If possible, upgrade
! 16: your fsck_ffs binary before using a new kernel.
! 17: None of this signals actual filesystem damage.
1.85 atatat 18:
19: 20030324:
20: sendmail version 8.12.8 was imported. Since sendmail is
21: now setgid to the smmsp group, and runs in "collection"
22: mode for most common activities, there is a new config
23: file called submit.cf that needs to live in /etc/mail.
24: The generic submit.cf sample in /usr/share/sendmail/cf
25: is named netbsd-msp.cf. Upgrading your regular sendmail
26: configuration file is also strongly advised.
27:
28: See the section named "MESSAGE SUBMISSION PROGRAM" in
29: the updated /usr/share/sendmail/README file for more
30: information.
1.82 wiz 31:
32: 20030117:
33: Texinfo was updated to 4.3. To avoid failures when trying to
34: build the included texinfo files, do:
35:
36: cd src/gnu/usr.bin/texinfo
37: make MKINFO=no dependall install
1.81 lukem 38:
39: 20021223:
40: The METALOG format changed slightly, to remove the leading
41: "${DESTDIR}" from path names.
42: This only affects people building with UNPRIVED.
43: For complete safety, remove the DESTDIR entirely and
44: update tools/mtree, before running make build.
1.80 lukem 45:
46: 20021219:
47: install(1) had a '-N dbdir' option added, to specify an
48: alternate location to look up users & groups (instead
49: of the host system passwd(5) and group(5) databases).
50:
51: The build system was modified to take advantage of
52: this option (using ${NETBSDSRCDIR}/etc), so if you
1.83 kei 53: use USETOOLS==no, you may have to rebuild and
1.80 lukem 54: reinstall usr.bin/xinstall first.
1.78 lukem 55:
56: 20021130:
57: fparseln(3) moved from libutil to libc.
58: If building to DESTDIR=/, reinstall the includes
59: and rebuild libc:
60: make includes
61: make do-lib-libc
62: If using build.sh, "cd tools/compat && make clean"
63: before rebuilding the tools.
1.77 lukem 64:
65: 20021126:
66: The mk.conf(5) variable SYS_INCLUDE has been deprecated,
67: including the optional "SYS_INCLUDE=symlinks" support.
68: All header files, including <sys/*.h> are copied into
69: /usr/include.
1.76 thorpej 70:
71: 20021121:
72: The C run-time support files crtbegin.o and crtend.o
73: (and their companions crtbeginS.o and crtendS.o) were
74: split up, with new crti.o and crtn.o files resulting.
75: This means that libtool needs to be rebuilt once the
76: new libraries are installed. The process of rebuilding
77: libtool will cause it to automatically notice the new
78: required files, but it *must* be rebuilt in order to
79: do this.
80:
81: An out-of-date libtool will result in shared libraries
82: which lack _init() and _fini() routines, which means that
83: their global contructors/destructors will not be invoked.
1.75 thorpej 84:
85: 20021121:
86: A bug related to how ARM ELF objects were tagged has been
87: corrected.
88:
89: NetBSD ARM ELF uses the soft-VFP floating point model by
90: default. However, the assembler lacked support for marking
91: objects as using the VFP floating point format, and the
1.79 wiz 92: compiler was not properly passing the flag indicating "soft-VFP"
1.75 thorpej 93: to the assembler.
94:
95: Unfortunately, this means that the linker will now consider
96: old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be
97: incompatible with new (properly marked) objects.
98:
99: The problem will only manifest itself if you attempt to compile
100: a new program using the fixed toolchain, and link that program
101: against old libraries which do not have the proper "softvfp"
102: markings. ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES
103: WILL CONTINUE TO WORK PROPERLY.
104:
105: The only work-around for the problem is to recompile all of
106: the libraries on the system. The easiest way to do this for
1.79 wiz 107: system libraries is to install a binary snapshot; they are
1.75 thorpej 108: generally available on releng.netbsd.org. Any packages you
109: have installed which supply libraries will have to be recompiled
110: if you wish to link new programs against those libraries.
111:
112: If you have questions about this matter, please contact
113: port-arm@netbsd.org.
1.73 provos 114:
115: 20021011:
116: Systrace has been improved to support privilege elevation.
117: Updating the kernel requires the userland part of systrace
1.79 wiz 118: to be rebuilt.
1.72 thorpej 119:
120: 20021010:
121: The config(8) grammar was changed to allow options to register
122: dependencies on attributes, as well as other options. Users
123: must update and reinstall usr.sbin/config before building a new
124: kernel.
1.70 thorpej 125:
126: 20021009:
127: A new attribute dependency syntax was introduced to config(8),
128: which is now used by the SCSI configuration description. Users
1.71 wiz 129: must update and reinstall usr.sbin/config before building a new
1.70 thorpej 130: kernel.
1.69 thorpej 131:
132: 20021003:
133: Several changes have been made to the autoconfiguration
134: framework. Users must update and reinstall usr.sbin/config
135: before building a new kernel.
1.74 jschauma 136:
137: 20021001:
138: The i386mp branch has been merged. To compile a kernel, users
139: will need to add the option 'cpu* at mainbus?' to their configuration
140: file. Multiprocessor kernels will need
141: ioapic* at mainbus? apid ?
142: options MULTIPROCESSOR
143: options COM_MPLOCK
1.68 lukem 144:
145: 20020922:
146: MKDYNAMICROOT=yes enabled by default, which means that
147: certain shared libraries are installed into /lib, the shared
148: linker is installed into /libexec, and all programs in /bin
149: and /sbin are dynamically linked.
150: If you do not use "make build", you should ensure that
151: you have the libraries and shared linker in the new locations,
152: with:
153: make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so
1.67 lukem 154:
155: 20020917:
156: USE_NEW_TOOLCHAIN has been replaced with:
157: - TOOLCHAIN_MISSING -- set to "yes" on platforms for which
158: there is no working in-tree toolchain (hppa, ns32k, sh5,
159: x86_64).
160: - EXTERNAL_TOOLCHAIN -- if defined by the user, points to the
1.79 wiz 161: root of an external toolchain (e.g. /usr/local/gnu). This
1.67 lukem 162: enables the cross-build framework even for TOOLCHAIN_MISSING
163: platforms.
1.66 gehenna 164:
165: 20020906:
166: gehenna-devsw has been merged into the trunk. Need to update and
1.79 wiz 167: reinstall usr.sbin/config before building the kernel.
1.65 lukem 168:
169: 20020822:
170: Crunched rescue tools (contents of /bin and /sbin, plus others)
171: are now provided in /rescue.
172:
173: To ensure that these are built statically linked (no matter
174: what the setting of LDSTATIC is), use a crunchgen(1) built
175: from sources newer than 20020820 (see the next entry).
176:
177: 20020820:
178: crunchgen(1) changed to ensure that the generated program
179: is statically linked.
180:
181: Solution: update and reinstall usr.bin/crunch
1.84 grant 182:
183: 20020605:
184: smmsp user/group has been added for sendmail.
185:
186: Add the following into /etc/group:
187:
188: smmsp:*:17:
189:
190: and the following to /etc/master.passwd (via vipw):
191:
192: smmsp:*:17:17::0:0:Sendmail Message Submission Program:/nonexistent:/sbin/nologin
1.61 itojun 193:
194: 20020515:
195: sshd user/group has been added. Need to hand add this in, or sshd
196: will not let you log in (with default, or UsePrivlegeSeparation=yes)
197:
198: Add the following into /etc/group:
199:
200: sshd:*:16:
201:
202: and the following to /etc/master.passwd (via vipw):
203:
1.63 enami 204: sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin
1.61 itojun 205:
1.79 wiz 206: Also /var/chroot/sshd directory needs to be present (digged as part of
207: the build process).
1.60 sommerfe 208:
209: 20020426:
210: NBUILDJOBS obsoleted in favor of just using -j.
1.59 lukem 211:
212: 20020426:
213: etc/postinstall added, which performs various checks for
214: configuration file updates and changes, and can fix most of
215: the problems identified.
216: This should make it much easier to upgrade a system's
217: configuration from earlier systems (as far back as NetBSD 1.5).
1.56 lukem 218:
219: 20020320:
1.79 wiz 220: <bsd.lib.mk> needs a new install(1) for its "-a cmd" support.
221: Build and install at usr.bin/xinstall before the build.
1.56 lukem 222:
1.55 itojun 223: 20020319:
1.79 wiz 224: Raw IPv6 socket now makes strict checking for sa_family and sa_len
225: on send(2) operation. Be sure to have sbin/rtsol and usr.sbin/rtsold
1.55 itojun 226: newer than November 2001 when you upgrade the kernel.
227:
1.54 itojun 228: 20020311:
229: ssh configuration files were moved from /etc to /etc/ssh. Beware
230: if you restart your machine from remote. Note that sshd.conf needs
231: to be changed (due to the use of "/etc" inside).
232:
233: 20020223:
1.53 matt 234: Users of the VAX port will need to rebuild and install gas
235: so it deal with the now present register prefix used in all
236: the VAX assembly files.
237:
1.50 itojun 238: 20020118:
239: ntpd user/group has been added. Need to hand add this in or builds
240: will break as mtree aborts early.
241:
242: Add the following into /etc/group:
243:
244: ntpd:*:15:
245:
246: and the following to /etc/master.passwd (via vipw):
247:
248: ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin
249:
1.49 jmc 250: 20011207:
251: If you're attempting to build a snapshot on sparc64 and are getting
252: reloc errors from the toolchain groff binary this means your native
253: toolchain has some broken C++ bits.
254:
255: To fix:
256:
257: Build a new toolchain (i.e. build.sh -t)
258: Use the new toolchain to build and install natively (i.e. /usr/lib)
259:
260: gnu/lib/libgcc
1.51 pooka 261: gnu/lib/libstdc++
1.49 jmc 262:
263: After this a snapshot will be able to be built.
264:
1.47 jmc 265: 20011201:
266: In order for a sparc64 build to work you must have a working awk. If
267: you've built and installed a system with the new toolchain up to this
1.52 wiz 268: point you do not have a working awk as its ability to do floating
1.47 jmc 269: point is broken.
270:
271: To build:
272:
273: remake and install gnu/lib/libgcc
274: remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links
1.48 jmc 275: against the new libgcc.a)
1.47 jmc 276:
1.46 thorpej 277: 20011128:
278: Kernel config information was changed to use defflag in
279: the various "files" files. Bug fixes to config(8) are
280: required in order for this to work properly. Make sure
281: to build and install in usr.sbin/config before attempting
282: to build a new kernel.
283:
1.45 yamt 284: 20011030:
285: libc/locale/wcstod.c now needs new lint(1). Update lint(1)
286: before building libc.
1.43 mason 287:
1.44 tv 288: 20011029:
289: The new document BUILDING.mdoc (view with nroff | more, or
290: see pre-generated .txt and .html versions) describes the build
291: procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
292: build process, are intended in the long run to replace this
293: manual update log.
294:
295: Users building a USE_NEW_TOOLCHAIN system should read the
296: BUILDING document for caveats. Generally, BUILDING supersedes
297: UPDATING for these systems, as tool updating is taken care of
298: by the new build system.
1.42 perry 299:
300: 20011028:
301: src/etc/Makefile now needs install to be able to handle
302: symlinks that point to nowhere. A bug in install that
303: prevented this was corrected.
304:
305: Solution: update and reinstall usr.bin/xinstall
306: Better Solution: Use the new toolchain and it will just work
307: for you.
1.40 lukem 308:
309: 20011006:
310: /etc/mtree/NetBSD.dist has been updated to take advantage of
311: absolute path support added to mtree(8). Older mtree(8)s don't
312: understand the format.
313:
314: Solution: update and reinstall usr.sbin/mtree
1.39 jmc 315:
316: 20011004:
317: Crunchgen has been updated to work via reach-over makefiles. Updating
318: is suggested before running a snapshot build
1.36 tv 319:
1.35 thorpej 320: 20010915:
321: The new "ubcperf" code committed by Chuck Silvers removed
322: a header file, uvm/uvm_vnode.h. There may be stale .depend
323: files that still reference this file.
324:
325: Solution: "make cleandir && make dependall" in affected
326: directories.
1.31 enami 327:
328: 20010803:
329: grep.info is now built from grep.texi using makeinfo. Since it
330: requires makeinfo v4.0, you need to install new texinfo before
331: building gnu/usr.bin/grep. To install new texinfo, please follow
332: the instruction described in 20010726 entry.
1.30 enami 333:
1.64 sommerfe 334: 20010803:
1.41 wiz 335: (i386 only): i386 kernel now uses new instructions like
336: `fxsave' which old gas doesn't understand. To build the
1.64 sommerfe 337: kernel successfully, you need to build and install a new toolchain,
338: (i.e., build.sh -t) or (temporarily) comment out "options I686_CPU"
339: from your kernel configuration until you rebuild your userland.
340: See 20011029 above and BUILDING file in this directory for more information.
341: [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]
1.29 bjh21 342:
343: 20010731:
344: Bootloader update on ELF platforms. DDB in kernels from before
345: this will be unable to read symbol tables provided by newer
346: bootloaders.
1.27 assar 347:
348: 20010726:
349: Texinfo was updated to 4.0. To avoid failures when trying to
1.28 assar 350: build the included texinfo files, do:
351:
352: cd src/gnu/usr.bin/texinfo
353: make MKINFO=no dependall install
1.25 thorpej 354:
355: 20010718:
356: Enabled correct .init/.fini processing in crt0. The way this
357: was done was to change a -I directive to cc(1), which means
358: make(1) will have a stale dependency (it will be checking the
359: timestamp on the wrong "dot_init.h").
360:
361: The symptom you will see is that new programs die with SIGSEGV
362: if you have a stale dependency.
363:
364: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
365: before starting your build.
1.26 thorpej 366:
367: 20010628:
368: A construct was added to uvm_page.h that uncovered a bug
369: in lint(1). If you get a warning/error about a non-portable
370: bitfield, update your lint(1) before proceeding.
1.21 jmc 371:
372: 20010226:
1.22 jmc 373: Added named user/group to system. Need to hand add this in or builds
1.21 jmc 374: will break as mtree aborts early.
375:
376: To work around add by hand:
377:
378: named:*:14:
379:
1.22 jmc 380: to /etc/group and add:
381:
382: named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin
383:
384: to master.passwd (use vipw for instance if doing by hand).
385:
386: Now a make build should progress.
1.18 jmc 387:
388: 20010219:
1.52 wiz 389: get/setprogname() added. Any hostprogs that may use this will need
1.20 jmc 390: to be bootstrapped manually until the host system is current.
1.18 jmc 391:
392: Known problems: sys/arch/macppc/stand/fixcoff
1.19 cgd 393: usr.sbin/config (adding -DMAKE_BOOTSTRAP to
394: CFLAGS and rebuilding should work)
1.20 jmc 395: usr.sbin/mdsetimage - Build a static copy if
396: building a snapshot before fully bootstrapped.
1.15 christos 397:
398: 20010204:
399: prepare the code to compile with stricter gcc flags. in
400: particular start eliminating redundant declarations. Yacc
401: needs to be installed before make build.
1.10 christos 402:
403: 20010114:
404: introduce .if commands(target) in make(1). You need to
405: bring everything up-to-date first, then without installing
1.23 tron 406: anything make and install in usr.bin/make, then proceed
1.10 christos 407: with make build.
1.9 sommerfe 408:
409: 20010101:
410: bsd.subdir.mk committed 20001230 had a bug which caused
411: afterinstall targets to run too soon; update again.
1.8 sommerfe 412:
413: 20001230:
414: New share/mk files needed to support .WAIT in SUBDIR variables.
415: If you get make errors,
416: (cd share/mk; make install)
417: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 418:
419: 20001019:
1.7 ad 420: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 421: major and minor numbers haven't changed, you should update your /dev
422: directory.
1.1 abs 423:
1.4 itojun 424: 20000929:
425: The following make directives are obsoleted.
426: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
427: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 428: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 429: additional library libcrypto_{idea,rc5}.
1.1 abs 430:
431:
432: Hints for a more successful build:
433: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 434: Build a new kernel first:
435: This makes sure that any new system calls or features
436: expected by the new userland will be present. This
437: helps to avoid critical errors when upgrading.
1.1 abs 438: Use object directories:
439: This helps to keep stale object
440: files from polluting the build if a Makefile "forgets"
441: about one. It also makes it easier to clean up after
442: a build. It's also necessary if you want to use the
443: same source tree for multiple machines.
444: To use object directories:
445: a) cd /usr/src ; make cleandir
1.2 mrg 446: b) Add "OBJMACHINE=yes" to /etc/mk.conf
447: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 448: d) cd /usr/src ; make build
1.2 mrg 449: Note that running "make obj" in a directory will create
450: in obj.$MACHINE directory.
1.1 abs 451: Build to a DESTDIR:
452: This helps to keep old
453: installed files (especially libraries) from interfering
454: with the new build.
455: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 456: variable before running make build. It should be set to
457: the pathname of an initially empty directory.
1.1 abs 458: Problems: you might need to update critical utilities
459: without using DESTDIR since nothing is executed
460: from what is installed in DESTDIR.
461: (See critical utils, below)
462: Build often:
463: This keeps critical utilities current enough to not choke
464: on any other part of the source tree that depends on up to
465: date functionality.
466:
467: What to do if things don't work:
468: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
469: When things don't work there is usually a few things that commonly

478: To make sure you rebuild something correctly you want to do
479: something like the following:
480: 1) Make sure the includes and .mk files are up to date.
481: 2) Make sure any program used to build the particular
482: utility is up to date. (yacc, lex, etc...)
483: 3) cd ...path/to/util...

536: Symptom:Complaints involving a Makefile.
1.17 erh 537: Fix: Rebuild usr.bin/make:
538: cd usr.bin/make && make && make install
539: Or, a failsafe method if that doesn't work:
540: cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin

557: Symptom:Obsolete intermediate files are used during compilation
558: Fix: Try the following sequence of commands in the directory in question.
559: make cleandir; rm `make print-objdir`; make cleandir; make obj
560: (If you built the tree without "make obj" in the past, obsolete files
561: may remain. The command tries to clean everything up)
