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