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.

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