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