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: ^^^^^^^^^^^^^^^
1.73 ! provos 10:
! 11: 20021011:
! 12: Systrace has been improved to support privilege elevation.
! 13: Updating the kernel requires the userland part of systrace
! 14: to be rebuild.
1.72 thorpej 15:
16: 20021010:
17: The config(8) grammar was changed to allow options to register
18: dependencies on attributes, as well as other options. Users
19: must update and reinstall usr.sbin/config before building a new
20: kernel.
1.70 thorpej 21:
22: 20021009:
23: A new attribute dependency syntax was introduced to config(8),
24: which is now used by the SCSI configuration description. Users
1.71 wiz 25: must update and reinstall usr.sbin/config before building a new
1.70 thorpej 26: kernel.
1.69 thorpej 27:
28: 20021003:
29: Several changes have been made to the autoconfiguration
30: framework. Users must update and reinstall usr.sbin/config
31: before building a new kernel.
1.68 lukem 32:
33: 20020922:
34: MKDYNAMICROOT=yes enabled by default, which means that
35: certain shared libraries are installed into /lib, the shared
36: linker is installed into /libexec, and all programs in /bin
37: and /sbin are dynamically linked.
38: If you do not use "make build", you should ensure that
39: you have the libraries and shared linker in the new locations,
40: with:
41: make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so
1.67 lukem 42:
43: 20020917:
44: USE_NEW_TOOLCHAIN has been replaced with:
45: - TOOLCHAIN_MISSING -- set to "yes" on platforms for which
46: there is no working in-tree toolchain (hppa, ns32k, sh5,
47: x86_64).
48: - EXTERNAL_TOOLCHAIN -- if defined by the user, points to the
49: root ofan external toolchain (e.g. /usr/local/gnu). This
50: enables the cross-build framework even for TOOLCHAIN_MISSING
51: platforms.
1.66 gehenna 52:
53: 20020906:
54: gehenna-devsw has been merged into the trunk. Need to update and
55: reinstall usr.sbin/config before build the kernel.
1.65 lukem 56:
57: 20020822:
58: Crunched rescue tools (contents of /bin and /sbin, plus others)
59: are now provided in /rescue.
60:
61: To ensure that these are built statically linked (no matter
62: what the setting of LDSTATIC is), use a crunchgen(1) built
63: from sources newer than 20020820 (see the next entry).
64:
65: 20020820:
66: crunchgen(1) changed to ensure that the generated program
67: is statically linked.
68:
69: Solution: update and reinstall usr.bin/crunch
1.61 itojun 70:
71: 20020515:
72: sshd user/group has been added. Need to hand add this in, or sshd
73: will not let you log in (with default, or UsePrivlegeSeparation=yes)
74:
75: Add the following into /etc/group:
76:
77: sshd:*:16:
78:
79: and the following to /etc/master.passwd (via vipw):
80:
1.63 enami 81: sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin
1.61 itojun 82:
1.62 jdolecek 83: also /var/chroot/sshd directory needs to be present (digged as a part of
1.61 itojun 84: build process).
1.60 sommerfe 85:
86: 20020426:
87: NBUILDJOBS obsoleted in favor of just using -j.
1.59 lukem 88:
89: 20020426:
90: etc/postinstall added, which performs various checks for
91: configuration file updates and changes, and can fix most of
92: the problems identified.
93: This should make it much easier to upgrade a system's
94: configuration from earlier systems (as far back as NetBSD 1.5).
1.56 lukem 95:
96: 20020320:
97: <bsd.lib.mk> needs a new install(1) for it's "-a cmd" support.
1.57 itojun 98: build and install at usr.bin/xinstall before the build.
1.56 lukem 99:
1.55 itojun 100: 20020319:
101: raw IPv6 socket now makes strict checking for sa_family and sa_len
102: on send(2) operation. be sure to have sbin/rtsol and usr.sbin/rtsold
103: newer than November 2001 when you upgrade the kernel.
104:
1.54 itojun 105: 20020311:
106: ssh configuration files were moved from /etc to /etc/ssh. Beware
107: if you restart your machine from remote. Note that sshd.conf needs
108: to be changed (due to the use of "/etc" inside).
109:
110: 20020223:
1.53 matt 111: Users of the VAX port will need to rebuild and install gas
112: so it deal with the now present register prefix used in all
113: the VAX assembly files.
114:
1.50 itojun 115: 20020118:
116:
117: ntpd user/group has been added. Need to hand add this in or builds
118: will break as mtree aborts early.
119:
120: Add the following into /etc/group:
121:
122: ntpd:*:15:
123:
124: and the following to /etc/master.passwd (via vipw):
125:
126: ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin
127:
1.49 jmc 128: 20011207:
129:
130: If you're attempting to build a snapshot on sparc64 and are getting
131: reloc errors from the toolchain groff binary this means your native
132: toolchain has some broken C++ bits.
133:
134: To fix:
135:
136: Build a new toolchain (i.e. build.sh -t)
137: Use the new toolchain to build and install natively (i.e. /usr/lib)
138:
139: gnu/lib/libgcc
1.51 pooka 140: gnu/lib/libstdc++
1.49 jmc 141:
142: After this a snapshot will be able to be built.
143:
1.47 jmc 144: 20011201:
145: In order for a sparc64 build to work you must have a working awk. If
146: you've built and installed a system with the new toolchain up to this
1.52 wiz 147: point you do not have a working awk as its ability to do floating
1.47 jmc 148: point is broken.
149:
150: To build:
151:
152: remake and install gnu/lib/libgcc
153: remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links
1.48 jmc 154: against the new libgcc.a)
1.47 jmc 155:
1.46 thorpej 156: 20011128:
157: Kernel config information was changed to use defflag in
158: the various "files" files. Bug fixes to config(8) are
159: required in order for this to work properly. Make sure
160: to build and install in usr.sbin/config before attempting
161: to build a new kernel.
162:
1.45 yamt 163: 20011030:
164: libc/locale/wcstod.c now needs new lint(1). Update lint(1)
165: before building libc.
1.43 mason 166:
1.44 tv 167: 20011029:
168: The new document BUILDING.mdoc (view with nroff | more, or
169: see pre-generated .txt and .html versions) describes the build
170: procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
171: build process, are intended in the long run to replace this
172: manual update log.
173:
174: Users building a USE_NEW_TOOLCHAIN system should read the
175: BUILDING document for caveats. Generally, BUILDING supersedes
176: UPDATING for these systems, as tool updating is taken care of
177: by the new build system.
1.42 perry 178:
179: 20011028:
180: src/etc/Makefile now needs install to be able to handle
181: symlinks that point to nowhere. A bug in install that
182: prevented this was corrected.
183:
184: Solution: update and reinstall usr.bin/xinstall
185: Better Solution: Use the new toolchain and it will just work
186: for you.
1.40 lukem 187:
188: 20011006:
189: /etc/mtree/NetBSD.dist has been updated to take advantage of
190: absolute path support added to mtree(8). Older mtree(8)s don't
191: understand the format.
192:
193: Solution: update and reinstall usr.sbin/mtree
1.39 jmc 194:
195: 20011004:
196: Crunchgen has been updated to work via reach-over makefiles. Updating
197: is suggested before running a snapshot build
1.36 tv 198:
1.35 thorpej 199: 20010915:
200: The new "ubcperf" code committed by Chuck Silvers removed
201: a header file, uvm/uvm_vnode.h. There may be stale .depend
202: files that still reference this file.
203:
204: Solution: "make cleandir && make dependall" in affected
205: directories.
1.31 enami 206:
207: 20010803:
208: grep.info is now built from grep.texi using makeinfo. Since it
209: requires makeinfo v4.0, you need to install new texinfo before
210: building gnu/usr.bin/grep. To install new texinfo, please follow
211: the instruction described in 20010726 entry.
1.30 enami 212:
1.64 sommerfe 213: 20010803:
1.41 wiz 214: (i386 only): i386 kernel now uses new instructions like
215: `fxsave' which old gas doesn't understand. To build the
1.64 sommerfe 216: kernel successfully, you need to build and install a new toolchain,
217: (i.e., build.sh -t) or (temporarily) comment out "options I686_CPU"
218: from your kernel configuration until you rebuild your userland.
219: See 20011029 above and BUILDING file in this directory for more information.
220: [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]
1.29 bjh21 221:
222: 20010731:
223: Bootloader update on ELF platforms. DDB in kernels from before
224: this will be unable to read symbol tables provided by newer
225: bootloaders.
1.27 assar 226:
227: 20010726:
228: Texinfo was updated to 4.0. To avoid failures when trying to
1.28 assar 229: build the included texinfo files, do:
230:
231: cd src/gnu/usr.bin/texinfo
232: make MKINFO=no dependall install
1.25 thorpej 233:
234: 20010718:
235: Enabled correct .init/.fini processing in crt0. The way this
236: was done was to change a -I directive to cc(1), which means
237: make(1) will have a stale dependency (it will be checking the
238: timestamp on the wrong "dot_init.h").
239:
240: The symptom you will see is that new programs die with SIGSEGV
241: if you have a stale dependency.
242:
243: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
244: before starting your build.
1.26 thorpej 245:
246: 20010628:
247: A construct was added to uvm_page.h that uncovered a bug
248: in lint(1). If you get a warning/error about a non-portable
249: bitfield, update your lint(1) before proceeding.
1.21 jmc 250:
251: 20010226:
1.22 jmc 252: Added named user/group to system. Need to hand add this in or builds
1.21 jmc 253: will break as mtree aborts early.
254:
255: To work around add by hand:
256:
257: named:*:14:
258:
1.22 jmc 259: to /etc/group and add:
260:
261: named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin
262:
263: to master.passwd (use vipw for instance if doing by hand).
264:
265: Now a make build should progress.
1.18 jmc 266:
267: 20010219:
1.52 wiz 268: get/setprogname() added. Any hostprogs that may use this will need
1.20 jmc 269: to be bootstrapped manually until the host system is current.
1.18 jmc 270:
271: Known problems: sys/arch/macppc/stand/fixcoff
1.19 cgd 272: usr.sbin/config (adding -DMAKE_BOOTSTRAP to
273: CFLAGS and rebuilding should work)
1.20 jmc 274: usr.sbin/mdsetimage - Build a static copy if
275: building a snapshot before fully bootstrapped.
1.15 christos 276:
277: 20010204:
278: prepare the code to compile with stricter gcc flags. in
279: particular start eliminating redundant declarations. Yacc
280: needs to be installed before make build.
1.10 christos 281:
282: 20010114:
283: introduce .if commands(target) in make(1). You need to
284: bring everything up-to-date first, then without installing
1.23 tron 285: anything make and install in usr.bin/make, then proceed
1.10 christos 286: with make build.
1.9 sommerfe 287:
288: 20010101:
289: bsd.subdir.mk committed 20001230 had a bug which caused
290: afterinstall targets to run too soon; update again.
1.8 sommerfe 291:
292: 20001230:
293: New share/mk files needed to support .WAIT in SUBDIR variables.
294: If you get make errors,
295: (cd share/mk; make install)
296: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 297:
298: 20001019:
1.7 ad 299: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 300: major and minor numbers haven't changed, you should update your /dev
301: directory.
1.1 abs 302:
1.4 itojun 303: 20000929:
304: The following make directives are obsoleted.
305: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
306: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 307: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 308: additional library libcrypto_{idea,rc5}.
1.1 abs 309:
310:
311: Hints for a more successful build:
312: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 313: Build a new kernel first:
314: This makes sure that any new system calls or features
315: expected by the new userland will be present. This
316: helps to avoid critical errors when upgrading.
1.1 abs 317: Use object directories:
318: This helps to keep stale object
319: files from polluting the build if a Makefile "forgets"
320: about one. It also makes it easier to clean up after
321: a build. It's also necessary if you want to use the
322: same source tree for multiple machines.
323: To use object directories:
324: a) cd /usr/src ; make cleandir
1.2 mrg 325: b) Add "OBJMACHINE=yes" to /etc/mk.conf
326: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 327: d) cd /usr/src ; make build
1.2 mrg 328: Note that running "make obj" in a directory will create
329: in obj.$MACHINE directory.
1.1 abs 330: Build to a DESTDIR:
331: This helps to keep old
332: installed files (especially libraries) from interfering
333: with the new build.
334: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 335: variable before running make build. It should be set to
336: the pathname of an initially empty directory.
1.1 abs 337: Problems: you might need to update critical utilities
338: without using DESTDIR since nothing is executed
339: from what is installed in DESTDIR.
340: (See critical utils, below)
341: Build often:
342: This keeps critical utilities current enough to not choke
343: on any other part of the source tree that depends on up to
344: date functionality.
345:
346: What to do if things don't work:
347: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
348: When things don't work there is usually a few things that commonly
349: should be done.
350: 1) make includes
351: This should be done automatically by make build.
352: 2) cd share/mk && make install
353: Again, automatically done by make build.
354:
355: Failsafe rebuild of a small part of the tree:
356: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
357: To make sure you rebuild something correctly you want to do
358: something like the following:
359: 1) Make sure the includes and .mk files are up to date.
360: 2) Make sure any program used to build the particular
361: utility is up to date. (yacc, lex, etc...)
362: 3) cd ...path/to/util...
363: make cleandir
364: rm ...all obj directories...
365: make cleandir # yes, again
366: make obj
367: make depend && make
368:
369: Failsafe rebuild of the entire tree:
370: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
371: If you really want to make sure the source tree is clean and
1.2 mrg 372: ready for a build try the following. Note that sourcing /etc/mk.conf
373: (a make(1) Makefile) in this manner is not right, and will not work
374: for anyone who uses any make(1) features in /etc/mk.conf.
