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.
1.74 ! jschauma 32:
! 33: 20021001:
! 34: The i386mp branch has been merged. To compile a kernel, users
! 35: will need to add the option 'cpu* at mainbus?' to their configuration
! 36: file. Multiprocessor kernels will need
! 37: ioapic* at mainbus? apid ?
! 38: options MULTIPROCESSOR
! 39: options COM_MPLOCK
1.68 lukem 40:
41: 20020922:
42: MKDYNAMICROOT=yes enabled by default, which means that
43: certain shared libraries are installed into /lib, the shared
44: linker is installed into /libexec, and all programs in /bin
45: and /sbin are dynamically linked.
46: If you do not use "make build", you should ensure that
47: you have the libraries and shared linker in the new locations,
48: with:
49: make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so
1.67 lukem 50:
51: 20020917:
52: USE_NEW_TOOLCHAIN has been replaced with:
53: - TOOLCHAIN_MISSING -- set to "yes" on platforms for which
54: there is no working in-tree toolchain (hppa, ns32k, sh5,
55: x86_64).
56: - EXTERNAL_TOOLCHAIN -- if defined by the user, points to the
57: root ofan external toolchain (e.g. /usr/local/gnu). This
58: enables the cross-build framework even for TOOLCHAIN_MISSING
59: platforms.
1.66 gehenna 60:
61: 20020906:
62: gehenna-devsw has been merged into the trunk. Need to update and
63: reinstall usr.sbin/config before build the kernel.
1.65 lukem 64:
65: 20020822:
66: Crunched rescue tools (contents of /bin and /sbin, plus others)
67: are now provided in /rescue.
68:
69: To ensure that these are built statically linked (no matter
70: what the setting of LDSTATIC is), use a crunchgen(1) built
71: from sources newer than 20020820 (see the next entry).
72:
73: 20020820:
74: crunchgen(1) changed to ensure that the generated program
75: is statically linked.
76:
77: Solution: update and reinstall usr.bin/crunch
1.61 itojun 78:
79: 20020515:
80: sshd user/group has been added. Need to hand add this in, or sshd
81: will not let you log in (with default, or UsePrivlegeSeparation=yes)
82:
83: Add the following into /etc/group:
84:
85: sshd:*:16:
86:
87: and the following to /etc/master.passwd (via vipw):
88:
1.63 enami 89: sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin
1.61 itojun 90:
1.62 jdolecek 91: also /var/chroot/sshd directory needs to be present (digged as a part of
1.61 itojun 92: build process).
1.60 sommerfe 93:
94: 20020426:
95: NBUILDJOBS obsoleted in favor of just using -j.
1.59 lukem 96:
97: 20020426:
98: etc/postinstall added, which performs various checks for
99: configuration file updates and changes, and can fix most of
100: the problems identified.
101: This should make it much easier to upgrade a system's
102: configuration from earlier systems (as far back as NetBSD 1.5).
1.56 lukem 103:
104: 20020320:
105: <bsd.lib.mk> needs a new install(1) for it's "-a cmd" support.
1.57 itojun 106: build and install at usr.bin/xinstall before the build.
1.56 lukem 107:
1.55 itojun 108: 20020319:
109: raw IPv6 socket now makes strict checking for sa_family and sa_len
110: on send(2) operation. be sure to have sbin/rtsol and usr.sbin/rtsold
111: newer than November 2001 when you upgrade the kernel.
112:
1.54 itojun 113: 20020311:
114: ssh configuration files were moved from /etc to /etc/ssh. Beware
115: if you restart your machine from remote. Note that sshd.conf needs
116: to be changed (due to the use of "/etc" inside).
117:
118: 20020223:
1.53 matt 119: Users of the VAX port will need to rebuild and install gas
120: so it deal with the now present register prefix used in all
121: the VAX assembly files.
122:
1.50 itojun 123: 20020118:
124:
125: ntpd user/group has been added. Need to hand add this in or builds
126: will break as mtree aborts early.
127:
128: Add the following into /etc/group:
129:
130: ntpd:*:15:
131:
132: and the following to /etc/master.passwd (via vipw):
133:
134: ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin
135:
1.49 jmc 136: 20011207:
137:
138: If you're attempting to build a snapshot on sparc64 and are getting
139: reloc errors from the toolchain groff binary this means your native
140: toolchain has some broken C++ bits.
141:
142: To fix:
143:
144: Build a new toolchain (i.e. build.sh -t)
145: Use the new toolchain to build and install natively (i.e. /usr/lib)
146:
147: gnu/lib/libgcc
1.51 pooka 148: gnu/lib/libstdc++
1.49 jmc 149:
150: After this a snapshot will be able to be built.
151:
1.47 jmc 152: 20011201:
153: In order for a sparc64 build to work you must have a working awk. If
154: you've built and installed a system with the new toolchain up to this
1.52 wiz 155: point you do not have a working awk as its ability to do floating
1.47 jmc 156: point is broken.
157:
158: To build:
159:
160: remake and install gnu/lib/libgcc
161: remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links
1.48 jmc 162: against the new libgcc.a)
1.47 jmc 163:
1.46 thorpej 164: 20011128:
165: Kernel config information was changed to use defflag in
166: the various "files" files. Bug fixes to config(8) are
167: required in order for this to work properly. Make sure
168: to build and install in usr.sbin/config before attempting
169: to build a new kernel.
170:
1.45 yamt 171: 20011030:
172: libc/locale/wcstod.c now needs new lint(1). Update lint(1)
173: before building libc.
1.43 mason 174:
1.44 tv 175: 20011029:
176: The new document BUILDING.mdoc (view with nroff | more, or
177: see pre-generated .txt and .html versions) describes the build
178: procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
179: build process, are intended in the long run to replace this
180: manual update log.
181:
182: Users building a USE_NEW_TOOLCHAIN system should read the
183: BUILDING document for caveats. Generally, BUILDING supersedes
184: UPDATING for these systems, as tool updating is taken care of
185: by the new build system.
1.42 perry 186:
187: 20011028:
188: src/etc/Makefile now needs install to be able to handle
189: symlinks that point to nowhere. A bug in install that
190: prevented this was corrected.
191:
192: Solution: update and reinstall usr.bin/xinstall
193: Better Solution: Use the new toolchain and it will just work
194: for you.
1.40 lukem 195:
196: 20011006:
197: /etc/mtree/NetBSD.dist has been updated to take advantage of
198: absolute path support added to mtree(8). Older mtree(8)s don't
199: understand the format.
200:
201: Solution: update and reinstall usr.sbin/mtree
1.39 jmc 202:
203: 20011004:
204: Crunchgen has been updated to work via reach-over makefiles. Updating
205: is suggested before running a snapshot build
1.36 tv 206:
1.35 thorpej 207: 20010915:
208: The new "ubcperf" code committed by Chuck Silvers removed
209: a header file, uvm/uvm_vnode.h. There may be stale .depend
210: files that still reference this file.
211:
212: Solution: "make cleandir && make dependall" in affected
213: directories.
1.31 enami 214:
215: 20010803:
216: grep.info is now built from grep.texi using makeinfo. Since it
217: requires makeinfo v4.0, you need to install new texinfo before
218: building gnu/usr.bin/grep. To install new texinfo, please follow
219: the instruction described in 20010726 entry.
1.30 enami 220:
1.64 sommerfe 221: 20010803:
1.41 wiz 222: (i386 only): i386 kernel now uses new instructions like
223: `fxsave' which old gas doesn't understand. To build the
1.64 sommerfe 224: kernel successfully, you need to build and install a new toolchain,
225: (i.e., build.sh -t) or (temporarily) comment out "options I686_CPU"
226: from your kernel configuration until you rebuild your userland.
227: See 20011029 above and BUILDING file in this directory for more information.
228: [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]
1.29 bjh21 229:
230: 20010731:
231: Bootloader update on ELF platforms. DDB in kernels from before
232: this will be unable to read symbol tables provided by newer
233: bootloaders.
1.27 assar 234:
235: 20010726:
236: Texinfo was updated to 4.0. To avoid failures when trying to
1.28 assar 237: build the included texinfo files, do:
238:
239: cd src/gnu/usr.bin/texinfo
240: make MKINFO=no dependall install
1.25 thorpej 241:
242: 20010718:
243: Enabled correct .init/.fini processing in crt0. The way this
244: was done was to change a -I directive to cc(1), which means
245: make(1) will have a stale dependency (it will be checking the
246: timestamp on the wrong "dot_init.h").
247:
248: The symptom you will see is that new programs die with SIGSEGV
249: if you have a stale dependency.
250:
251: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
252: before starting your build.
1.26 thorpej 253:
254: 20010628:
255: A construct was added to uvm_page.h that uncovered a bug
256: in lint(1). If you get a warning/error about a non-portable
257: bitfield, update your lint(1) before proceeding.
1.21 jmc 258:
259: 20010226:
1.22 jmc 260: Added named user/group to system. Need to hand add this in or builds
1.21 jmc 261: will break as mtree aborts early.
262:
263: To work around add by hand:
264:
265: named:*:14:
266:
1.22 jmc 267: to /etc/group and add:
268:
269: named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin
270:
271: to master.passwd (use vipw for instance if doing by hand).
272:
273: Now a make build should progress.
1.18 jmc 274:
275: 20010219:
1.52 wiz 276: get/setprogname() added. Any hostprogs that may use this will need
1.20 jmc 277: to be bootstrapped manually until the host system is current.
1.18 jmc 278:
279: Known problems: sys/arch/macppc/stand/fixcoff
1.19 cgd 280: usr.sbin/config (adding -DMAKE_BOOTSTRAP to
281: CFLAGS and rebuilding should work)
1.20 jmc 282: usr.sbin/mdsetimage - Build a static copy if
283: building a snapshot before fully bootstrapped.
1.15 christos 284:
285: 20010204:
286: prepare the code to compile with stricter gcc flags. in
287: particular start eliminating redundant declarations. Yacc
288: needs to be installed before make build.
1.10 christos 289:
290: 20010114:
291: introduce .if commands(target) in make(1). You need to
292: bring everything up-to-date first, then without installing
1.23 tron 293: anything make and install in usr.bin/make, then proceed
1.10 christos 294: with make build.
1.9 sommerfe 295:
296: 20010101:
297: bsd.subdir.mk committed 20001230 had a bug which caused
298: afterinstall targets to run too soon; update again.
1.8 sommerfe 299:
300: 20001230:
301: New share/mk files needed to support .WAIT in SUBDIR variables.
302: If you get make errors,
303: (cd share/mk; make install)
304: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 305:
306: 20001019:
1.7 ad 307: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 308: major and minor numbers haven't changed, you should update your /dev
309: directory.
1.1 abs 310:
1.4 itojun 311: 20000929:
312: The following make directives are obsoleted.
313: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
314: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 315: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 316: additional library libcrypto_{idea,rc5}.
1.1 abs 317:
318:
319: Hints for a more successful build:
320: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 321: Build a new kernel first:
322: This makes sure that any new system calls or features
323: expected by the new userland will be present. This
324: helps to avoid critical errors when upgrading.
1.1 abs 325: Use object directories:
326: This helps to keep stale object
327: files from polluting the build if a Makefile "forgets"
328: about one. It also makes it easier to clean up after
329: a build. It's also necessary if you want to use the
330: same source tree for multiple machines.
331: To use object directories:
332: a) cd /usr/src ; make cleandir
1.2 mrg 333: b) Add "OBJMACHINE=yes" to /etc/mk.conf
334: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 335: d) cd /usr/src ; make build
1.2 mrg 336: Note that running "make obj" in a directory will create
337: in obj.$MACHINE directory.
1.1 abs 338: Build to a DESTDIR:
339: This helps to keep old
340: installed files (especially libraries) from interfering
341: with the new build.
342: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 343: variable before running make build. It should be set to
344: the pathname of an initially empty directory.
1.1 abs 345: Problems: you might need to update critical utilities
346: without using DESTDIR since nothing is executed
347: from what is installed in DESTDIR.
348: (See critical utils, below)
349: Build often:
350: This keeps critical utilities current enough to not choke
351: on any other part of the source tree that depends on up to
352: date functionality.
353:
354: What to do if things don't work:
355: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
356: When things don't work there is usually a few things that commonly
357: should be done.
358: 1) make includes
359: This should be done automatically by make build.
360: 2) cd share/mk && make install
361: Again, automatically done by make build.
362:
363: Failsafe rebuild of a small part of the tree:
364: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
365: To make sure you rebuild something correctly you want to do
366: something like the following:
367: 1) Make sure the includes and .mk files are up to date.
368: 2) Make sure any program used to build the particular
369: utility is up to date. (yacc, lex, etc...)
370: 3) cd ...path/to/util...
371: make cleandir
372: rm ...all obj directories...
373: make cleandir # yes, again
374: make obj
375: make depend && make
376:
377: Failsafe rebuild of the entire tree:
378: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
379: If you really want to make sure the source tree is clean and
1.2 mrg 380: ready for a build try the following. Note that sourcing /etc/mk.conf
381: (a make(1) Makefile) in this manner is not right, and will not work
382: for anyone who uses any make(1) features in /etc/mk.conf.
