1.53 ! matt 10: 20010223:
! 11: Users of the VAX port will need to rebuild and install gas
! 12: so it deal with the now present register prefix used in all
! 13: the VAX assembly files.
! 14:
1.50 itojun 15: 20020118:
16:
17: ntpd user/group has been added. Need to hand add this in or builds
18: will break as mtree aborts early.
19:
20: Add the following into /etc/group:
21:
22: ntpd:*:15:
23:
24: and the following to /etc/master.passwd (via vipw):
25:
26: ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin
27:
1.49 jmc 28: 20011207:
29:
30: If you're attempting to build a snapshot on sparc64 and are getting
31: reloc errors from the toolchain groff binary this means your native
32: toolchain has some broken C++ bits.
33:
34: To fix:
35:
36: Build a new toolchain (i.e. build.sh -t)
37: Use the new toolchain to build and install natively (i.e. /usr/lib)
38:
39: gnu/lib/libgcc
1.51 pooka 40: gnu/lib/libstdc++
1.49 jmc 41:
42: After this a snapshot will be able to be built.
43:
1.47 jmc 44: 20011201:
45: In order for a sparc64 build to work you must have a working awk. If
46: you've built and installed a system with the new toolchain up to this
1.52 wiz 47: point you do not have a working awk as its ability to do floating
1.47 jmc 48: point is broken.
49:
50: To build:
51:
52: remake and install gnu/lib/libgcc
53: remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links
1.48 jmc 54: against the new libgcc.a)
1.47 jmc 55:
1.46 thorpej 56: 20011128:
57: Kernel config information was changed to use defflag in
58: the various "files" files. Bug fixes to config(8) are
59: required in order for this to work properly. Make sure
60: to build and install in usr.sbin/config before attempting
61: to build a new kernel.
62:
1.45 yamt 63: 20011030:
64: libc/locale/wcstod.c now needs new lint(1). Update lint(1)
65: before building libc.
1.43 mason 66:
1.44 tv 67: 20011029:
68: The new document BUILDING.mdoc (view with nroff | more, or
69: see pre-generated .txt and .html versions) describes the build
70: procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
71: build process, are intended in the long run to replace this
72: manual update log.
73:
74: Users building a USE_NEW_TOOLCHAIN system should read the
75: BUILDING document for caveats. Generally, BUILDING supersedes
76: UPDATING for these systems, as tool updating is taken care of
77: by the new build system.
1.42 perry 78:
79: 20011028:
80: src/etc/Makefile now needs install to be able to handle
81: symlinks that point to nowhere. A bug in install that
82: prevented this was corrected.
83:
84: Solution: update and reinstall usr.bin/xinstall
85: Better Solution: Use the new toolchain and it will just work
86: for you.
1.40 lukem 87:
88: 20011006:
89: /etc/mtree/NetBSD.dist has been updated to take advantage of
90: absolute path support added to mtree(8). Older mtree(8)s don't
91: understand the format.
92:
93: Solution: update and reinstall usr.sbin/mtree
1.39 jmc 94:
95: 20011004:
96: Crunchgen has been updated to work via reach-over makefiles. Updating
97: is suggested before running a snapshot build
1.36 tv 98:
1.35 thorpej 99: 20010915:
100: The new "ubcperf" code committed by Chuck Silvers removed
101: a header file, uvm/uvm_vnode.h. There may be stale .depend
102: files that still reference this file.
103:
104: Solution: "make cleandir && make dependall" in affected
105: directories.
1.31 enami 106:
107: 20010803:
108: grep.info is now built from grep.texi using makeinfo. Since it
109: requires makeinfo v4.0, you need to install new texinfo before
110: building gnu/usr.bin/grep. To install new texinfo, please follow
111: the instruction described in 20010726 entry.
1.30 enami 112:
113: 20010803:
1.41 wiz 114: (i386 only): i386 kernel now uses new instructions like
115: `fxsave' which old gas doesn't understand. To build the
1.52 wiz 116: kernel successfully, you need to build and install new gas
1.41 wiz 117: (gnu/usr.bin/gas.new), or (temporarily) comment out
118: "options I686_CPU" from your kernel configuration until you
119: rebuilt your userland (and got a new gas).
1.29 bjh21 120:
121: 20010731:
122: Bootloader update on ELF platforms. DDB in kernels from before
123: this will be unable to read symbol tables provided by newer
124: bootloaders.
1.27 assar 125:
126: 20010726:
127: Texinfo was updated to 4.0. To avoid failures when trying to
1.28 assar 128: build the included texinfo files, do:
129:
130: cd src/gnu/usr.bin/texinfo
131: make MKINFO=no dependall install
1.25 thorpej 132:
133: 20010718:
134: Enabled correct .init/.fini processing in crt0. The way this
135: was done was to change a -I directive to cc(1), which means
136: make(1) will have a stale dependency (it will be checking the
137: timestamp on the wrong "dot_init.h").
138:
139: The symptom you will see is that new programs die with SIGSEGV
140: if you have a stale dependency.
141:
142: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
143: before starting your build.
1.26 thorpej 144:
145: 20010628:
146: A construct was added to uvm_page.h that uncovered a bug
147: in lint(1). If you get a warning/error about a non-portable
148: bitfield, update your lint(1) before proceeding.
1.21 jmc 149:
150: 20010226:
1.22 jmc 151: Added named user/group to system. Need to hand add this in or builds
1.21 jmc 152: will break as mtree aborts early.
153:
154: To work around add by hand:
155:
156: named:*:14:
157:
1.22 jmc 158: to /etc/group and add:
159:
160: named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin
161:
162: to master.passwd (use vipw for instance if doing by hand).
163:
164: Now a make build should progress.
1.18 jmc 165:
166: 20010219:
1.52 wiz 167: get/setprogname() added. Any hostprogs that may use this will need
1.20 jmc 168: to be bootstrapped manually until the host system is current.
1.18 jmc 169:
170: Known problems: sys/arch/macppc/stand/fixcoff
1.19 cgd 171: usr.sbin/config (adding -DMAKE_BOOTSTRAP to
172: CFLAGS and rebuilding should work)
1.20 jmc 173: usr.sbin/mdsetimage - Build a static copy if
174: building a snapshot before fully bootstrapped.
1.15 christos 175:
176: 20010204:
177: prepare the code to compile with stricter gcc flags. in
178: particular start eliminating redundant declarations. Yacc
179: needs to be installed before make build.
1.10 christos 180:
181: 20010114:
182: introduce .if commands(target) in make(1). You need to
183: bring everything up-to-date first, then without installing
1.23 tron 184: anything make and install in usr.bin/make, then proceed
1.10 christos 185: with make build.
1.9 sommerfe 186:
187: 20010101:
188: bsd.subdir.mk committed 20001230 had a bug which caused
189: afterinstall targets to run too soon; update again.
1.8 sommerfe 190:
191: 20001230:
192: New share/mk files needed to support .WAIT in SUBDIR variables.
193: If you get make errors,
194: (cd share/mk; make install)
195: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 196:
197: 20001019:
1.7 ad 198: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 199: major and minor numbers haven't changed, you should update your /dev
200: directory.
1.1 abs 201:
1.4 itojun 202: 20000929:
203: The following make directives are obsoleted.
204: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
205: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 206: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 207: additional library libcrypto_{idea,rc5}.
1.1 abs 208:
209:
210: Hints for a more successful build:
211: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 212: Build a new kernel first:
213: This makes sure that any new system calls or features
214: expected by the new userland will be present. This
215: helps to avoid critical errors when upgrading.
1.1 abs 216: Use object directories:
217: This helps to keep stale object
218: files from polluting the build if a Makefile "forgets"
219: about one. It also makes it easier to clean up after
220: a build. It's also necessary if you want to use the
221: same source tree for multiple machines.
222: To use object directories:
223: a) cd /usr/src ; make cleandir
1.2 mrg 224: b) Add "OBJMACHINE=yes" to /etc/mk.conf
225: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 226: d) cd /usr/src ; make build
1.2 mrg 227: Note that running "make obj" in a directory will create
228: in obj.$MACHINE directory.
1.1 abs 229: Build to a DESTDIR:
230: This helps to keep old
231: installed files (especially libraries) from interfering
232: with the new build.
233: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 234: variable before running make build. It should be set to
235: the pathname of an initially empty directory.
1.1 abs 236: Problems: you might need to update critical utilities
237: without using DESTDIR since nothing is executed
238: from what is installed in DESTDIR.
239: (See critical utils, below)
240: Build often:
241: This keeps critical utilities current enough to not choke
242: on any other part of the source tree that depends on up to
243: date functionality.
244:
245: What to do if things don't work:
246: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
247: When things don't work there is usually a few things that commonly
248: should be done.
249: 1) make includes
250: This should be done automatically by make build.
251: 2) cd share/mk && make install
252: Again, automatically done by make build.
253:
254: Failsafe rebuild of a small part of the tree:
255: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
256: To make sure you rebuild something correctly you want to do
257: something like the following:
258: 1) Make sure the includes and .mk files are up to date.
259: 2) Make sure any program used to build the particular
260: utility is up to date. (yacc, lex, etc...)
261: 3) cd ...path/to/util...
262: make cleandir
263: rm ...all obj directories...
264: make cleandir # yes, again
265: make obj
266: make depend && make
267:
268: Failsafe rebuild of the entire tree:
269: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
270: If you really want to make sure the source tree is clean and
1.2 mrg 271: ready for a build try the following. Note that sourcing /etc/mk.conf
272: (a make(1) Makefile) in this manner is not right, and will not work
273: for anyone who uses any make(1) features in /etc/mk.conf.
1.1 abs 274:
275: ---cut here---
276: #!/bin/sh
277: . /etc/mk.conf
278:
279: if [ -z $BSDSRCDIR ] ; then
280: BSDSRCDIR=/usr/src

282: if [ \! -d $BSDSRCDIR ] ; then
283: echo Unable to find sources
284: exit 1
285: fi
