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