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