! 11: 20021121:
! 12: The C run-time support files crtbegin.o and crtend.o
! 13: (and their companions crtbeginS.o and crtendS.o) were
! 14: split up, with new crti.o and crtn.o files resulting.
! 15: This means that libtool needs to be rebuilt once the
! 16: new libraries are installed. The process of rebuilding
! 17: libtool will cause it to automatically notice the new
! 18: required files, but it *must* be rebuilt in order to
! 19: do this.
! 20:
! 21: An out-of-date libtool will result in shared libraries
! 22: which lack _init() and _fini() routines, which means that
! 23: their global contructors/destructors will not be invoked.

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