9: ^^^^^^^^^^^^^^^
1.66 ! gehenna 10:
! 11: 20020906:
! 12: gehenna-devsw has been merged into the trunk. Need to update and
! 13: reinstall usr.sbin/config before build the kernel.
1.65 lukem 14:
15: 20020822:
16: Crunched rescue tools (contents of /bin and /sbin, plus others)
17: are now provided in /rescue.
18:
19: To ensure that these are built statically linked (no matter
20: what the setting of LDSTATIC is), use a crunchgen(1) built
21: from sources newer than 20020820 (see the next entry).
22:
23: 20020820:
24: crunchgen(1) changed to ensure that the generated program
25: is statically linked.
26:
27: Solution: update and reinstall usr.bin/crunch
1.61 itojun 28:
29: 20020515:
30: sshd user/group has been added. Need to hand add this in, or sshd
31: will not let you log in (with default, or UsePrivlegeSeparation=yes)
32:
33: Add the following into /etc/group:
34:
35: sshd:*:16:
36:
37: and the following to /etc/master.passwd (via vipw):
38:
1.63 enami 39: sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin
1.61 itojun 40:
1.62 jdolecek 41: also /var/chroot/sshd directory needs to be present (digged as a part of
1.61 itojun 42: build process).
1.60 sommerfe 43:
44: 20020426:
45: NBUILDJOBS obsoleted in favor of just using -j.
1.59 lukem 46:
47: 20020426:
48: etc/postinstall added, which performs various checks for
49: configuration file updates and changes, and can fix most of
50: the problems identified.
51: This should make it much easier to upgrade a system's
52: configuration from earlier systems (as far back as NetBSD 1.5).
1.56 lukem 53:
54: 20020320:
55: <bsd.lib.mk> needs a new install(1) for it's "-a cmd" support.
1.57 itojun 56: build and install at usr.bin/xinstall before the build.
1.56 lukem 57:
1.55 itojun 58: 20020319:
59: raw IPv6 socket now makes strict checking for sa_family and sa_len
60: on send(2) operation. be sure to have sbin/rtsol and usr.sbin/rtsold
61: newer than November 2001 when you upgrade the kernel.
62:
1.54 itojun 63: 20020311:
64: ssh configuration files were moved from /etc to /etc/ssh. Beware
65: if you restart your machine from remote. Note that sshd.conf needs
66: to be changed (due to the use of "/etc" inside).
67:
68: 20020223:
1.53 matt 69: Users of the VAX port will need to rebuild and install gas
70: so it deal with the now present register prefix used in all
71: the VAX assembly files.
72:
1.50 itojun 73: 20020118:
74:
75: ntpd user/group has been added. Need to hand add this in or builds
76: will break as mtree aborts early.
77:
78: Add the following into /etc/group:
79:
80: ntpd:*:15:
81:
82: and the following to /etc/master.passwd (via vipw):
83:
84: ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin
85:
1.49 jmc 86: 20011207:
87:
88: If you're attempting to build a snapshot on sparc64 and are getting
89: reloc errors from the toolchain groff binary this means your native
90: toolchain has some broken C++ bits.
91:
92: To fix:
93:
94: Build a new toolchain (i.e. build.sh -t)
95: Use the new toolchain to build and install natively (i.e. /usr/lib)
96:
97: gnu/lib/libgcc
1.51 pooka 98: gnu/lib/libstdc++
1.49 jmc 99:
100: After this a snapshot will be able to be built.
101:
1.47 jmc 102: 20011201:
103: In order for a sparc64 build to work you must have a working awk. If
104: you've built and installed a system with the new toolchain up to this
1.52 wiz 105: point you do not have a working awk as its ability to do floating
1.47 jmc 106: point is broken.
107:
108: To build:
109:
110: remake and install gnu/lib/libgcc
111: remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links
1.48 jmc 112: against the new libgcc.a)
1.47 jmc 113:
1.46 thorpej 114: 20011128:
115: Kernel config information was changed to use defflag in
116: the various "files" files. Bug fixes to config(8) are
117: required in order for this to work properly. Make sure
118: to build and install in usr.sbin/config before attempting
119: to build a new kernel.
120:
1.45 yamt 121: 20011030:
122: libc/locale/wcstod.c now needs new lint(1). Update lint(1)
123: before building libc.
1.43 mason 124:
1.44 tv 125: 20011029:
126: The new document BUILDING.mdoc (view with nroff | more, or
127: see pre-generated .txt and .html versions) describes the build
128: procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
129: build process, are intended in the long run to replace this
130: manual update log.
131:
132: Users building a USE_NEW_TOOLCHAIN system should read the
133: BUILDING document for caveats. Generally, BUILDING supersedes
134: UPDATING for these systems, as tool updating is taken care of
135: by the new build system.
1.42 perry 136:
137: 20011028:
138: src/etc/Makefile now needs install to be able to handle
139: symlinks that point to nowhere. A bug in install that
140: prevented this was corrected.
141:
142: Solution: update and reinstall usr.bin/xinstall
143: Better Solution: Use the new toolchain and it will just work
144: for you.
1.40 lukem 145:
146: 20011006:
147: /etc/mtree/NetBSD.dist has been updated to take advantage of
148: absolute path support added to mtree(8). Older mtree(8)s don't
149: understand the format.
150:
151: Solution: update and reinstall usr.sbin/mtree
1.39 jmc 152:
153: 20011004:
154: Crunchgen has been updated to work via reach-over makefiles. Updating
155: is suggested before running a snapshot build
1.36 tv 156:
1.35 thorpej 157: 20010915:
158: The new "ubcperf" code committed by Chuck Silvers removed
159: a header file, uvm/uvm_vnode.h. There may be stale .depend
160: files that still reference this file.
161:
162: Solution: "make cleandir && make dependall" in affected
163: directories.
1.31 enami 164:
165: 20010803:
166: grep.info is now built from grep.texi using makeinfo. Since it
167: requires makeinfo v4.0, you need to install new texinfo before
168: building gnu/usr.bin/grep. To install new texinfo, please follow
169: the instruction described in 20010726 entry.
1.30 enami 170:
1.64 sommerfe 171: 20010803:
1.41 wiz 172: (i386 only): i386 kernel now uses new instructions like
173: `fxsave' which old gas doesn't understand. To build the
1.64 sommerfe 174: kernel successfully, you need to build and install a new toolchain,
175: (i.e., build.sh -t) or (temporarily) comment out "options I686_CPU"
176: from your kernel configuration until you rebuild your userland.
177: See 20011029 above and BUILDING file in this directory for more information.
178: [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]
1.29 bjh21 179:
180: 20010731:
181: Bootloader update on ELF platforms. DDB in kernels from before
182: this will be unable to read symbol tables provided by newer
183: bootloaders.
1.27 assar 184:
185: 20010726:
186: Texinfo was updated to 4.0. To avoid failures when trying to
1.28 assar 187: build the included texinfo files, do:
188:
189: cd src/gnu/usr.bin/texinfo
190: make MKINFO=no dependall install
1.25 thorpej 191:
192: 20010718:
193: Enabled correct .init/.fini processing in crt0. The way this
194: was done was to change a -I directive to cc(1), which means
195: make(1) will have a stale dependency (it will be checking the
196: timestamp on the wrong "dot_init.h").
197:
198: The symptom you will see is that new programs die with SIGSEGV
199: if you have a stale dependency.
200:
201: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
202: before starting your build.
1.26 thorpej 203:
204: 20010628:
205: A construct was added to uvm_page.h that uncovered a bug
206: in lint(1). If you get a warning/error about a non-portable
207: bitfield, update your lint(1) before proceeding.
1.21 jmc 208:
209: 20010226:
1.22 jmc 210: Added named user/group to system. Need to hand add this in or builds
1.21 jmc 211: will break as mtree aborts early.
212:
213: To work around add by hand:
214:
215: named:*:14:
216:
1.22 jmc 217: to /etc/group and add:
218:
219: named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin
220:
221: to master.passwd (use vipw for instance if doing by hand).
222:
223: Now a make build should progress.
1.18 jmc 224:
225: 20010219:
1.52 wiz 226: get/setprogname() added. Any hostprogs that may use this will need
1.20 jmc 227: to be bootstrapped manually until the host system is current.
1.18 jmc 228:
229: Known problems: sys/arch/macppc/stand/fixcoff
1.19 cgd 230: usr.sbin/config (adding -DMAKE_BOOTSTRAP to
231: CFLAGS and rebuilding should work)
1.20 jmc 232: usr.sbin/mdsetimage - Build a static copy if
233: building a snapshot before fully bootstrapped.
1.15 christos 234:
235: 20010204:
236: prepare the code to compile with stricter gcc flags. in
237: particular start eliminating redundant declarations. Yacc
238: needs to be installed before make build.
1.10 christos 239:
240: 20010114:
241: introduce .if commands(target) in make(1). You need to
242: bring everything up-to-date first, then without installing
1.23 tron 243: anything make and install in usr.bin/make, then proceed
1.10 christos 244: with make build.
1.9 sommerfe 245:
246: 20010101:
247: bsd.subdir.mk committed 20001230 had a bug which caused
248: afterinstall targets to run too soon; update again.
1.8 sommerfe 249:
250: 20001230:
251: New share/mk files needed to support .WAIT in SUBDIR variables.
252: If you get make errors,
253: (cd share/mk; make install)
254: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 255:
256: 20001019:
1.7 ad 257: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 258: major and minor numbers haven't changed, you should update your /dev
259: directory.
1.1 abs 260:
1.4 itojun 261: 20000929:
262: The following make directives are obsoleted.
263: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
264: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 265: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 266: additional library libcrypto_{idea,rc5}.
1.1 abs 267:
268:
269: Hints for a more successful build:
270: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 271: Build a new kernel first:
272: This makes sure that any new system calls or features
273: expected by the new userland will be present. This
274: helps to avoid critical errors when upgrading.
1.1 abs 275: Use object directories:
276: This helps to keep stale object
277: files from polluting the build if a Makefile "forgets"
278: about one. It also makes it easier to clean up after
279: a build. It's also necessary if you want to use the
280: same source tree for multiple machines.
281: To use object directories:
282: a) cd /usr/src ; make cleandir
1.2 mrg 283: b) Add "OBJMACHINE=yes" to /etc/mk.conf
284: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 285: d) cd /usr/src ; make build
1.2 mrg 286: Note that running "make obj" in a directory will create
287: in obj.$MACHINE directory.
1.1 abs 288: Build to a DESTDIR:
289: This helps to keep old
290: installed files (especially libraries) from interfering
291: with the new build.
292: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 293: variable before running make build. It should be set to
294: the pathname of an initially empty directory.
1.1 abs 295: Problems: you might need to update critical utilities
296: without using DESTDIR since nothing is executed
297: from what is installed in DESTDIR.
298: (See critical utils, below)
299: Build often:
300: This keeps critical utilities current enough to not choke
301: on any other part of the source tree that depends on up to
302: date functionality.
303:
304: What to do if things don't work:
305: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
306: When things don't work there is usually a few things that commonly
307: should be done.
308: 1) make includes
309: This should be done automatically by make build.
310: 2) cd share/mk && make install
311: Again, automatically done by make build.
312:
313: Failsafe rebuild of a small part of the tree:
314: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
315: To make sure you rebuild something correctly you want to do
316: something like the following:
317: 1) Make sure the includes and .mk files are up to date.
318: 2) Make sure any program used to build the particular
319: utility is up to date. (yacc, lex, etc...)
320: 3) cd ...path/to/util...
321: make cleandir
322: rm ...all obj directories...
323: make cleandir # yes, again
324: make obj
325: make depend && make
326:
327: Failsafe rebuild of the entire tree:
328: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
329: If you really want to make sure the source tree is clean and
1.2 mrg 330: ready for a build try the following. Note that sourcing /etc/mk.conf
331: (a make(1) Makefile) in this manner is not right, and will not work
332: for anyone who uses any make(1) features in /etc/mk.conf.
