9: ^^^^^^^^^^^^^^^
1.67 ! lukem 10:
! 11: 20020917:
! 12: USE_NEW_TOOLCHAIN has been replaced with:
! 13: - TOOLCHAIN_MISSING -- set to "yes" on platforms for which
! 14: there is no working in-tree toolchain (hppa, ns32k, sh5,
! 15: x86_64).
! 16: - EXTERNAL_TOOLCHAIN -- if defined by the user, points to the
! 17: root ofan external toolchain (e.g. /usr/local/gnu). This
! 18: enables the cross-build framework even for TOOLCHAIN_MISSING
! 19: platforms.
1.66 gehenna 20:
21: 20020906:
22: gehenna-devsw has been merged into the trunk. Need to update and
23: reinstall usr.sbin/config before build the kernel.
1.65 lukem 24:
25: 20020822:
26: Crunched rescue tools (contents of /bin and /sbin, plus others)
27: are now provided in /rescue.
28:
29: To ensure that these are built statically linked (no matter
30: what the setting of LDSTATIC is), use a crunchgen(1) built
31: from sources newer than 20020820 (see the next entry).
32:
33: 20020820:
34: crunchgen(1) changed to ensure that the generated program
35: is statically linked.
36:
37: Solution: update and reinstall usr.bin/crunch
1.61 itojun 38:
39: 20020515:
40: sshd user/group has been added. Need to hand add this in, or sshd
41: will not let you log in (with default, or UsePrivlegeSeparation=yes)
42:
43: Add the following into /etc/group:
44:
45: sshd:*:16:
46:
47: and the following to /etc/master.passwd (via vipw):
48:
1.63 enami 49: sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin
1.61 itojun 50:
1.62 jdolecek 51: also /var/chroot/sshd directory needs to be present (digged as a part of
1.61 itojun 52: build process).
1.60 sommerfe 53:
54: 20020426:
55: NBUILDJOBS obsoleted in favor of just using -j.
1.59 lukem 56:
57: 20020426:
58: etc/postinstall added, which performs various checks for
59: configuration file updates and changes, and can fix most of
60: the problems identified.
61: This should make it much easier to upgrade a system's
62: configuration from earlier systems (as far back as NetBSD 1.5).
1.56 lukem 63:
64: 20020320:
65: <bsd.lib.mk> needs a new install(1) for it's "-a cmd" support.
1.57 itojun 66: build and install at usr.bin/xinstall before the build.
1.56 lukem 67:
1.55 itojun 68: 20020319:
69: raw IPv6 socket now makes strict checking for sa_family and sa_len
70: on send(2) operation. be sure to have sbin/rtsol and usr.sbin/rtsold
71: newer than November 2001 when you upgrade the kernel.
72:
1.54 itojun 73: 20020311:
74: ssh configuration files were moved from /etc to /etc/ssh. Beware
75: if you restart your machine from remote. Note that sshd.conf needs
76: to be changed (due to the use of "/etc" inside).
77:
78: 20020223:
1.53 matt 79: Users of the VAX port will need to rebuild and install gas
80: so it deal with the now present register prefix used in all
81: the VAX assembly files.
82:
1.50 itojun 83: 20020118:
84:
85: ntpd user/group has been added. Need to hand add this in or builds
86: will break as mtree aborts early.
87:
88: Add the following into /etc/group:
89:
90: ntpd:*:15:
91:
92: and the following to /etc/master.passwd (via vipw):
93:
94: ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin
95:
1.49 jmc 96: 20011207:
97:
98: If you're attempting to build a snapshot on sparc64 and are getting
99: reloc errors from the toolchain groff binary this means your native
100: toolchain has some broken C++ bits.
101:
102: To fix:
103:
104: Build a new toolchain (i.e. build.sh -t)
105: Use the new toolchain to build and install natively (i.e. /usr/lib)
106:
107: gnu/lib/libgcc
1.51 pooka 108: gnu/lib/libstdc++
1.49 jmc 109:
110: After this a snapshot will be able to be built.
111:
1.47 jmc 112: 20011201:
113: In order for a sparc64 build to work you must have a working awk. If
114: you've built and installed a system with the new toolchain up to this
1.52 wiz 115: point you do not have a working awk as its ability to do floating
1.47 jmc 116: point is broken.
117:
118: To build:
119:
120: remake and install gnu/lib/libgcc
121: remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links
1.48 jmc 122: against the new libgcc.a)
1.47 jmc 123:
1.46 thorpej 124: 20011128:
125: Kernel config information was changed to use defflag in
126: the various "files" files. Bug fixes to config(8) are
127: required in order for this to work properly. Make sure
128: to build and install in usr.sbin/config before attempting
129: to build a new kernel.
130:
1.45 yamt 131: 20011030:
132: libc/locale/wcstod.c now needs new lint(1). Update lint(1)
133: before building libc.
1.43 mason 134:
1.44 tv 135: 20011029:
136: The new document BUILDING.mdoc (view with nroff | more, or
137: see pre-generated .txt and .html versions) describes the build
138: procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
139: build process, are intended in the long run to replace this
140: manual update log.
141:
142: Users building a USE_NEW_TOOLCHAIN system should read the
143: BUILDING document for caveats. Generally, BUILDING supersedes
144: UPDATING for these systems, as tool updating is taken care of
145: by the new build system.
1.42 perry 146:
147: 20011028:
148: src/etc/Makefile now needs install to be able to handle
149: symlinks that point to nowhere. A bug in install that
150: prevented this was corrected.
151:
152: Solution: update and reinstall usr.bin/xinstall
153: Better Solution: Use the new toolchain and it will just work
154: for you.
1.40 lukem 155:
156: 20011006:
157: /etc/mtree/NetBSD.dist has been updated to take advantage of
158: absolute path support added to mtree(8). Older mtree(8)s don't
159: understand the format.
160:
161: Solution: update and reinstall usr.sbin/mtree
1.39 jmc 162:
163: 20011004:
164: Crunchgen has been updated to work via reach-over makefiles. Updating
165: is suggested before running a snapshot build
1.36 tv 166:
1.35 thorpej 167: 20010915:
168: The new "ubcperf" code committed by Chuck Silvers removed
169: a header file, uvm/uvm_vnode.h. There may be stale .depend
170: files that still reference this file.
171:
172: Solution: "make cleandir && make dependall" in affected
173: directories.
1.31 enami 174:
175: 20010803:
176: grep.info is now built from grep.texi using makeinfo. Since it
177: requires makeinfo v4.0, you need to install new texinfo before
178: building gnu/usr.bin/grep. To install new texinfo, please follow
179: the instruction described in 20010726 entry.
1.30 enami 180:
1.64 sommerfe 181: 20010803:
1.41 wiz 182: (i386 only): i386 kernel now uses new instructions like
183: `fxsave' which old gas doesn't understand. To build the
1.64 sommerfe 184: kernel successfully, you need to build and install a new toolchain,
185: (i.e., build.sh -t) or (temporarily) comment out "options I686_CPU"
186: from your kernel configuration until you rebuild your userland.
187: See 20011029 above and BUILDING file in this directory for more information.
188: [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]
1.29 bjh21 189:
190: 20010731:
191: Bootloader update on ELF platforms. DDB in kernels from before
192: this will be unable to read symbol tables provided by newer
193: bootloaders.
1.27 assar 194:
195: 20010726:
196: Texinfo was updated to 4.0. To avoid failures when trying to
1.28 assar 197: build the included texinfo files, do:
198:
199: cd src/gnu/usr.bin/texinfo
200: make MKINFO=no dependall install
1.25 thorpej 201:
202: 20010718:
203: Enabled correct .init/.fini processing in crt0. The way this
204: was done was to change a -I directive to cc(1), which means
205: make(1) will have a stale dependency (it will be checking the
206: timestamp on the wrong "dot_init.h").
207:
208: The symptom you will see is that new programs die with SIGSEGV
209: if you have a stale dependency.
210:
211: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
212: before starting your build.
1.26 thorpej 213:
214: 20010628:
215: A construct was added to uvm_page.h that uncovered a bug
216: in lint(1). If you get a warning/error about a non-portable
217: bitfield, update your lint(1) before proceeding.
1.21 jmc 218:
219: 20010226:
1.22 jmc 220: Added named user/group to system. Need to hand add this in or builds
1.21 jmc 221: will break as mtree aborts early.
222:
223: To work around add by hand:
224:
225: named:*:14:
226:
1.22 jmc 227: to /etc/group and add:
228:
229: named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin
230:
231: to master.passwd (use vipw for instance if doing by hand).
232:
233: Now a make build should progress.
1.18 jmc 234:
235: 20010219:
1.52 wiz 236: get/setprogname() added. Any hostprogs that may use this will need
1.20 jmc 237: to be bootstrapped manually until the host system is current.
1.18 jmc 238:
239: Known problems: sys/arch/macppc/stand/fixcoff
1.19 cgd 240: usr.sbin/config (adding -DMAKE_BOOTSTRAP to
241: CFLAGS and rebuilding should work)
1.20 jmc 242: usr.sbin/mdsetimage - Build a static copy if
243: building a snapshot before fully bootstrapped.
1.15 christos 244:
245: 20010204:
246: prepare the code to compile with stricter gcc flags. in
247: particular start eliminating redundant declarations. Yacc
248: needs to be installed before make build.
1.10 christos 249:
250: 20010114:
251: introduce .if commands(target) in make(1). You need to
252: bring everything up-to-date first, then without installing
1.23 tron 253: anything make and install in usr.bin/make, then proceed
1.10 christos 254: with make build.
1.9 sommerfe 255:
256: 20010101:
257: bsd.subdir.mk committed 20001230 had a bug which caused
258: afterinstall targets to run too soon; update again.
1.8 sommerfe 259:
260: 20001230:
261: New share/mk files needed to support .WAIT in SUBDIR variables.
262: If you get make errors,
263: (cd share/mk; make install)
264: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 265:
266: 20001019:
1.7 ad 267: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 268: major and minor numbers haven't changed, you should update your /dev
269: directory.
1.1 abs 270:
1.4 itojun 271: 20000929:
272: The following make directives are obsoleted.
273: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
274: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 275: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 276: additional library libcrypto_{idea,rc5}.
1.1 abs 277:
278:
279: Hints for a more successful build:
280: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 281: Build a new kernel first:
282: This makes sure that any new system calls or features
283: expected by the new userland will be present. This
284: helps to avoid critical errors when upgrading.
1.1 abs 285: Use object directories:
286: This helps to keep stale object
287: files from polluting the build if a Makefile "forgets"
288: about one. It also makes it easier to clean up after
289: a build. It's also necessary if you want to use the
290: same source tree for multiple machines.
291: To use object directories:
292: a) cd /usr/src ; make cleandir
1.2 mrg 293: b) Add "OBJMACHINE=yes" to /etc/mk.conf
294: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 295: d) cd /usr/src ; make build
1.2 mrg 296: Note that running "make obj" in a directory will create
297: in obj.$MACHINE directory.
1.1 abs 298: Build to a DESTDIR:
299: This helps to keep old
300: installed files (especially libraries) from interfering
301: with the new build.
302: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 303: variable before running make build. It should be set to
304: the pathname of an initially empty directory.
1.1 abs 305: Problems: you might need to update critical utilities
306: without using DESTDIR since nothing is executed
307: from what is installed in DESTDIR.
308: (See critical utils, below)
309: Build often:
310: This keeps critical utilities current enough to not choke
311: on any other part of the source tree that depends on up to
312: date functionality.
313:
314: What to do if things don't work:
315: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
316: When things don't work there is usually a few things that commonly
317: should be done.
318: 1) make includes
319: This should be done automatically by make build.
320: 2) cd share/mk && make install
321: Again, automatically done by make build.
322:
323: Failsafe rebuild of a small part of the tree:
324: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
325: To make sure you rebuild something correctly you want to do
326: something like the following:
327: 1) Make sure the includes and .mk files are up to date.
328: 2) Make sure any program used to build the particular
329: utility is up to date. (yacc, lex, etc...)
330: 3) cd ...path/to/util...
331: make cleandir
332: rm ...all obj directories...
333: make cleandir # yes, again
334: make obj
335: make depend && make
336:
337: Failsafe rebuild of the entire tree:
338: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
339: If you really want to make sure the source tree is clean and
1.2 mrg 340: ready for a build try the following. Note that sourcing /etc/mk.conf
341: (a make(1) Makefile) in this manner is not right, and will not work
342: for anyone who uses any make(1) features in /etc/mk.conf.
