1.1 abs 2:
3: This file is intended to be a brief introduction to the build
4: process and a reference on what to do if something doesn't work.

8: Recent changes:
9: ^^^^^^^^^^^^^^^
1.72 ! thorpej 10:
! 11: 20021010:
! 12: The config(8) grammar was changed to allow options to register
! 13: dependencies on attributes, as well as other options. Users
! 14: must update and reinstall usr.sbin/config before building a new
! 15: kernel.
1.70 thorpej 16:
17: 20021009:
18: A new attribute dependency syntax was introduced to config(8),
19: which is now used by the SCSI configuration description. Users
1.71 wiz 20: must update and reinstall usr.sbin/config before building a new
1.70 thorpej 21: kernel.
1.69 thorpej 22:
23: 20021003:
24: Several changes have been made to the autoconfiguration
25: framework. Users must update and reinstall usr.sbin/config
26: before building a new kernel.
1.68 lukem 27:
28: 20020922:
29: MKDYNAMICROOT=yes enabled by default, which means that
30: certain shared libraries are installed into /lib, the shared
31: linker is installed into /libexec, and all programs in /bin
32: and /sbin are dynamically linked.
33: If you do not use "make build", you should ensure that
34: you have the libraries and shared linker in the new locations,
35: with:
36: make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so
1.67 lukem 37:
38: 20020917:
39: USE_NEW_TOOLCHAIN has been replaced with:
40: - TOOLCHAIN_MISSING -- set to "yes" on platforms for which
41: there is no working in-tree toolchain (hppa, ns32k, sh5,
42: x86_64).
43: - EXTERNAL_TOOLCHAIN -- if defined by the user, points to the
44: root ofan external toolchain (e.g. /usr/local/gnu). This
45: enables the cross-build framework even for TOOLCHAIN_MISSING
46: platforms.
1.66 gehenna 47:
48: 20020906:
49: gehenna-devsw has been merged into the trunk. Need to update and
50: reinstall usr.sbin/config before build the kernel.
1.65 lukem 51:
52: 20020822:
53: Crunched rescue tools (contents of /bin and /sbin, plus others)
54: are now provided in /rescue.
55:
56: To ensure that these are built statically linked (no matter
57: what the setting of LDSTATIC is), use a crunchgen(1) built
58: from sources newer than 20020820 (see the next entry).
59:
60: 20020820:
61: crunchgen(1) changed to ensure that the generated program
62: is statically linked.
63:
64: Solution: update and reinstall usr.bin/crunch
1.61 itojun 65:
66: 20020515:
67: sshd user/group has been added. Need to hand add this in, or sshd
68: will not let you log in (with default, or UsePrivlegeSeparation=yes)
69:
70: Add the following into /etc/group:
71:
72: sshd:*:16:
73:
74: and the following to /etc/master.passwd (via vipw):
75:
1.63 enami 76: sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin
1.61 itojun 77:
1.62 jdolecek 78: also /var/chroot/sshd directory needs to be present (digged as a part of
1.61 itojun 79: build process).
1.60 sommerfe 80:
81: 20020426:
82: NBUILDJOBS obsoleted in favor of just using -j.
1.59 lukem 83:
84: 20020426:
85: etc/postinstall added, which performs various checks for
86: configuration file updates and changes, and can fix most of
87: the problems identified.
88: This should make it much easier to upgrade a system's
89: configuration from earlier systems (as far back as NetBSD 1.5).
1.56 lukem 90:
91: 20020320:
92: <bsd.lib.mk> needs a new install(1) for it's "-a cmd" support.
1.57 itojun 93: build and install at usr.bin/xinstall before the build.
1.56 lukem 94:
1.55 itojun 95: 20020319:
96: raw IPv6 socket now makes strict checking for sa_family and sa_len
97: on send(2) operation. be sure to have sbin/rtsol and usr.sbin/rtsold
98: newer than November 2001 when you upgrade the kernel.
99:
1.54 itojun 100: 20020311:
101: ssh configuration files were moved from /etc to /etc/ssh. Beware
102: if you restart your machine from remote. Note that sshd.conf needs
103: to be changed (due to the use of "/etc" inside).
104:
105: 20020223:
1.53 matt 106: Users of the VAX port will need to rebuild and install gas
107: so it deal with the now present register prefix used in all
108: the VAX assembly files.
109:
1.50 itojun 110: 20020118:
111:
112: ntpd user/group has been added. Need to hand add this in or builds
113: will break as mtree aborts early.
114:
115: Add the following into /etc/group:
116:
117: ntpd:*:15:
118:
119: and the following to /etc/master.passwd (via vipw):
120:
121: ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin
122:
1.49 jmc 123: 20011207:
124:
125: If you're attempting to build a snapshot on sparc64 and are getting
126: reloc errors from the toolchain groff binary this means your native
127: toolchain has some broken C++ bits.
128:
129: To fix:
130:
131: Build a new toolchain (i.e. build.sh -t)
132: Use the new toolchain to build and install natively (i.e. /usr/lib)
133:
134: gnu/lib/libgcc
1.51 pooka 135: gnu/lib/libstdc++
1.49 jmc 136:
137: After this a snapshot will be able to be built.
138:
1.47 jmc 139: 20011201:
140: In order for a sparc64 build to work you must have a working awk. If
141: you've built and installed a system with the new toolchain up to this
1.52 wiz 142: point you do not have a working awk as its ability to do floating
1.47 jmc 143: point is broken.
144:
145: To build:
146:
147: remake and install gnu/lib/libgcc
148: remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links
1.48 jmc 149: against the new libgcc.a)
1.47 jmc 150:
1.46 thorpej 151: 20011128:
152: Kernel config information was changed to use defflag in
153: the various "files" files. Bug fixes to config(8) are
154: required in order for this to work properly. Make sure
155: to build and install in usr.sbin/config before attempting
156: to build a new kernel.
157:
1.45 yamt 158: 20011030:
159: libc/locale/wcstod.c now needs new lint(1). Update lint(1)
160: before building libc.
1.43 mason 161:
1.44 tv 162: 20011029:
163: The new document BUILDING.mdoc (view with nroff | more, or
164: see pre-generated .txt and .html versions) describes the build
165: procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
166: build process, are intended in the long run to replace this
167: manual update log.
168:
169: Users building a USE_NEW_TOOLCHAIN system should read the
170: BUILDING document for caveats. Generally, BUILDING supersedes
171: UPDATING for these systems, as tool updating is taken care of
172: by the new build system.
1.42 perry 173:
174: 20011028:
175: src/etc/Makefile now needs install to be able to handle
176: symlinks that point to nowhere. A bug in install that
177: prevented this was corrected.
178:
179: Solution: update and reinstall usr.bin/xinstall
180: Better Solution: Use the new toolchain and it will just work
181: for you.
1.40 lukem 182:
183: 20011006:
184: /etc/mtree/NetBSD.dist has been updated to take advantage of
185: absolute path support added to mtree(8). Older mtree(8)s don't
186: understand the format.
187:
188: Solution: update and reinstall usr.sbin/mtree
1.39 jmc 189:
190: 20011004:
191: Crunchgen has been updated to work via reach-over makefiles. Updating
192: is suggested before running a snapshot build
1.36 tv 193:
1.35 thorpej 194: 20010915:
195: The new "ubcperf" code committed by Chuck Silvers removed
196: a header file, uvm/uvm_vnode.h. There may be stale .depend
197: files that still reference this file.
198:
199: Solution: "make cleandir && make dependall" in affected
200: directories.
1.31 enami 201:
202: 20010803:
203: grep.info is now built from grep.texi using makeinfo. Since it
204: requires makeinfo v4.0, you need to install new texinfo before
205: building gnu/usr.bin/grep. To install new texinfo, please follow
206: the instruction described in 20010726 entry.
1.30 enami 207:
1.64 sommerfe 208: 20010803:
1.41 wiz 209: (i386 only): i386 kernel now uses new instructions like
210: `fxsave' which old gas doesn't understand. To build the
1.64 sommerfe 211: kernel successfully, you need to build and install a new toolchain,
212: (i.e., build.sh -t) or (temporarily) comment out "options I686_CPU"
213: from your kernel configuration until you rebuild your userland.
214: See 20011029 above and BUILDING file in this directory for more information.
215: [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]
1.29 bjh21 216:
217: 20010731:
218: Bootloader update on ELF platforms. DDB in kernels from before
219: this will be unable to read symbol tables provided by newer
220: bootloaders.
1.27 assar 221:
222: 20010726:
223: Texinfo was updated to 4.0. To avoid failures when trying to
1.28 assar 224: build the included texinfo files, do:
225:
226: cd src/gnu/usr.bin/texinfo
227: make MKINFO=no dependall install
1.25 thorpej 228:
229: 20010718:
230: Enabled correct .init/.fini processing in crt0. The way this
231: was done was to change a -I directive to cc(1), which means
232: make(1) will have a stale dependency (it will be checking the
233: timestamp on the wrong "dot_init.h").
234:
235: The symptom you will see is that new programs die with SIGSEGV
236: if you have a stale dependency.
237:
238: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
239: before starting your build.
1.26 thorpej 240:
241: 20010628:
242: A construct was added to uvm_page.h that uncovered a bug
243: in lint(1). If you get a warning/error about a non-portable
244: bitfield, update your lint(1) before proceeding.
1.21 jmc 245:
246: 20010226:
1.22 jmc 247: Added named user/group to system. Need to hand add this in or builds
1.21 jmc 248: will break as mtree aborts early.
249:
250: To work around add by hand:
251:
252: named:*:14:
253:
1.22 jmc 254: to /etc/group and add:
255:
256: named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin
257:
258: to master.passwd (use vipw for instance if doing by hand).
259:
260: Now a make build should progress.
1.18 jmc 261:
262: 20010219:
1.52 wiz 263: get/setprogname() added. Any hostprogs that may use this will need
1.20 jmc 264: to be bootstrapped manually until the host system is current.
1.18 jmc 265:
266: Known problems: sys/arch/macppc/stand/fixcoff
1.19 cgd 267: usr.sbin/config (adding -DMAKE_BOOTSTRAP to
268: CFLAGS and rebuilding should work)
1.20 jmc 269: usr.sbin/mdsetimage - Build a static copy if
270: building a snapshot before fully bootstrapped.
1.15 christos 271:
272: 20010204:
273: prepare the code to compile with stricter gcc flags. in
274: particular start eliminating redundant declarations. Yacc
275: needs to be installed before make build.
1.10 christos 276:
277: 20010114:
278: introduce .if commands(target) in make(1). You need to
279: bring everything up-to-date first, then without installing
1.23 tron 280: anything make and install in usr.bin/make, then proceed
1.10 christos 281: with make build.
1.9 sommerfe 282:
283: 20010101:
284: bsd.subdir.mk committed 20001230 had a bug which caused
285: afterinstall targets to run too soon; update again.
1.8 sommerfe 286:
287: 20001230:
288: New share/mk files needed to support .WAIT in SUBDIR variables.
289: If you get make errors,
290: (cd share/mk; make install)
291: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 292:
293: 20001019:
1.7 ad 294: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 295: major and minor numbers haven't changed, you should update your /dev
296: directory.
1.1 abs 297:
1.4 itojun 298: 20000929:
299: The following make directives are obsoleted.
300: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
301: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 302: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 303: additional library libcrypto_{idea,rc5}.
1.1 abs 304:
305:
306: Hints for a more successful build:
307: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 308: Build a new kernel first:
309: This makes sure that any new system calls or features
310: expected by the new userland will be present. This
311: helps to avoid critical errors when upgrading.
1.1 abs 312: Use object directories:
313: This helps to keep stale object
314: files from polluting the build if a Makefile "forgets"
315: about one. It also makes it easier to clean up after
316: a build. It's also necessary if you want to use the
317: same source tree for multiple machines.
318: To use object directories:
319: a) cd /usr/src ; make cleandir
1.2 mrg 320: b) Add "OBJMACHINE=yes" to /etc/mk.conf
321: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 322: d) cd /usr/src ; make build
1.2 mrg 323: Note that running "make obj" in a directory will create
324: in obj.$MACHINE directory.
1.1 abs 325: Build to a DESTDIR:
326: This helps to keep old
327: installed files (especially libraries) from interfering
328: with the new build.
329: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 330: variable before running make build. It should be set to
331: the pathname of an initially empty directory.
1.1 abs 332: Problems: you might need to update critical utilities
333: without using DESTDIR since nothing is executed
334: from what is installed in DESTDIR.
335: (See critical utils, below)
336: Build often:
337: This keeps critical utilities current enough to not choke
338: on any other part of the source tree that depends on up to
339: date functionality.
340:
341: What to do if things don't work:
342: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
343: When things don't work there is usually a few things that commonly
344: should be done.
345: 1) make includes
346: This should be done automatically by make build.
347: 2) cd share/mk && make install
348: Again, automatically done by make build.
349:
350: Failsafe rebuild of a small part of the tree:
351: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
352: To make sure you rebuild something correctly you want to do
353: something like the following:
354: 1) Make sure the includes and .mk files are up to date.
355: 2) Make sure any program used to build the particular
356: utility is up to date. (yacc, lex, etc...)
357: 3) cd ...path/to/util...
358: make cleandir
359: rm ...all obj directories...
360: make cleandir # yes, again
361: make obj
362: make depend && make
363:
364: Failsafe rebuild of the entire tree:
365: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
366: If you really want to make sure the source tree is clean and
1.2 mrg 367: ready for a build try the following. Note that sourcing /etc/mk.conf
368: (a make(1) Makefile) in this manner is not right, and will not work
369: for anyone who uses any make(1) features in /etc/mk.conf.
