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

264
265 Critical utilities:
266 ^^^^^^^^^^^^^^^^^^^
267 gnu/usr.bin/egcs
268 usr.bin/compile_et
269 usr.bin/make
270 usr.bin/yacc
271 usr.bin/lex
272 usr.bin/xlint
273 usr.sbin/config
274
275 Other problems and possible solutions:
276 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
277 Symptom:Unreasonable compiler errors.
278 Fix: Rebuild gnu/usr.bin/egcs
279
280 Symptom:Complaints involving a Makefile.
281 Fix: Rebuild usr.bin/make:
282 cd usr.bin/make && make && make install
283 Or, a failsafe method if that doesn't work:
284 cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
285
286 Fix: Make sure .mk files are up to date.
287 cd share/mk && make install
288
289 Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
290 Fix: Rebuild usr.sbin/config
291
292 Symptom:
293 Fix: Rebuild usr.bin/yacc
294
295 Symptom:
296 Fix: Rebuild usr.bin/lex
297
298 Symptom:
299 Fix: rm /usr/lib/libbfd.a
300
301 Symptom:Obsolete intermediate files are used during compilation
302 Fix: Try the following sequence of commands in the directory in question.
303 make cleandir; rm `make print-objdir`; make cleandir; make obj
304 (If you built the tree without "make obj" in the past, obsolete files
305 may remain. The command tries to clean everything up)
306
307 Symptom:.../sysinst/run.c:xx: warning: initialization from incompatible pointer type
308 Fix: Rebuild and install usr.bin/menuc
309
310 Symptom:mklocale not found during build in share/locale/ctype
311 Fix: Build and install usr.bin/mklocale
312
313 Symptom:undefined reference to `__assert13'
314 Fix: Rebuild and install lib/libc
315
316 Symptom:usr.sbin/config fails to build.
317 Fix: Try building with -DMAKE_BOOTSTRAP added to CFLAGS in Makefile.
318
319 Symptom:undefined reference to `getprogname' or `setprogname'
320 Fix: Rebuild and install lib/libc
321
322 Symptom:lint does not understand the '-X' option
323 Fix: May need to build & install libs with NOLINT=1 before rebuilding lint
