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