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