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73: An out-of-date libtool will result in shared libraries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

528: Symptom:Complaints involving a Makefile.
1.17 erh 529: Fix: Rebuild usr.bin/make:
530: cd usr.bin/make && make && make install

551: make cleandir; rm `make print-objdir`; make cleandir; make obj
552: (If you built the tree without "make obj" in the past, obsolete files
553: may remain. The command tries to clean everything up)
