1.50 ! itojun 10: 20020118:
! 11:
! 12: ntpd user/group has been added. Need to hand add this in or builds
! 13: will break as mtree aborts early.
! 14:
! 15: Add the following into /etc/group:
! 16:
! 17: ntpd:*:15:
! 18:
! 19: and the following to /etc/master.passwd (via vipw):
! 20:
! 21: ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin

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