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: ^^^^^^^^^^^^^^^
1.80 ! lukem 10:
! 11: 20021219:
! 12: install(1) had a '-N dbdir' option added, to specify an
! 13: alternate location to look up users & groups (instead
! 14: of the host system passwd(5) and group(5) databases).
! 15:
! 16: The build system was modified to take advantage of
! 17: this option (using ${NETBSDSRCDIR}/etc), so if you
! 18: use USE_TOOLS==no, you may have to rebuild and
! 19: reinstall usr.bin/xinstall first.
1.78 lukem 20:
21: 20021130:
22: fparseln(3) moved from libutil to libc.
23: If building to DESTDIR=/, reinstall the includes
24: and rebuild libc:
25: make includes
26: make do-lib-libc
27: If using build.sh, "cd tools/compat && make clean"
28: before rebuilding the tools.
1.77 lukem 29:
30: 20021126:
31: The mk.conf(5) variable SYS_INCLUDE has been deprecated,
32: including the optional "SYS_INCLUDE=symlinks" support.
33: All header files, including <sys/*.h> are copied into
34: /usr/include.
1.76 thorpej 35:
36: 20021121:
37: The C run-time support files crtbegin.o and crtend.o
38: (and their companions crtbeginS.o and crtendS.o) were
39: split up, with new crti.o and crtn.o files resulting.
40: This means that libtool needs to be rebuilt once the
41: new libraries are installed. The process of rebuilding
42: libtool will cause it to automatically notice the new
43: required files, but it *must* be rebuilt in order to
44: do this.
45:
46: An out-of-date libtool will result in shared libraries
47: which lack _init() and _fini() routines, which means that
48: their global contructors/destructors will not be invoked.
1.75 thorpej 49:
50: 20021121:
51: A bug related to how ARM ELF objects were tagged has been
52: corrected.
53:
54: NetBSD ARM ELF uses the soft-VFP floating point model by
55: default. However, the assembler lacked support for marking
56: objects as using the VFP floating point format, and the
1.79 wiz 57: compiler was not properly passing the flag indicating "soft-VFP"
1.75 thorpej 58: to the assembler.
59:
60: Unfortunately, this means that the linker will now consider
61: old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be
62: incompatible with new (properly marked) objects.
63:
64: The problem will only manifest itself if you attempt to compile
65: a new program using the fixed toolchain, and link that program
66: against old libraries which do not have the proper "softvfp"
67: markings. ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES
68: WILL CONTINUE TO WORK PROPERLY.
69:
70: The only work-around for the problem is to recompile all of
71: the libraries on the system. The easiest way to do this for
1.79 wiz 72: system libraries is to install a binary snapshot; they are
1.75 thorpej 73: generally available on releng.netbsd.org. Any packages you
74: have installed which supply libraries will have to be recompiled
75: if you wish to link new programs against those libraries.
76:
77: If you have questions about this matter, please contact
78: port-arm@netbsd.org.
1.73 provos 79:
80: 20021011:
81: Systrace has been improved to support privilege elevation.
82: Updating the kernel requires the userland part of systrace
1.79 wiz 83: to be rebuilt.
1.72 thorpej 84:
85: 20021010:
86: The config(8) grammar was changed to allow options to register
87: dependencies on attributes, as well as other options. Users
88: must update and reinstall usr.sbin/config before building a new
89: kernel.
1.70 thorpej 90:
91: 20021009:
92: A new attribute dependency syntax was introduced to config(8),
93: which is now used by the SCSI configuration description. Users
1.71 wiz 94: must update and reinstall usr.sbin/config before building a new
1.70 thorpej 95: kernel.
1.69 thorpej 96:
97: 20021003:
98: Several changes have been made to the autoconfiguration
99: framework. Users must update and reinstall usr.sbin/config
100: before building a new kernel.
1.74 jschauma 101:
102: 20021001:
103: The i386mp branch has been merged. To compile a kernel, users
104: will need to add the option 'cpu* at mainbus?' to their configuration
105: file. Multiprocessor kernels will need
106: ioapic* at mainbus? apid ?
107: options MULTIPROCESSOR
108: options COM_MPLOCK
1.68 lukem 109:
110: 20020922:
111: MKDYNAMICROOT=yes enabled by default, which means that
112: certain shared libraries are installed into /lib, the shared
113: linker is installed into /libexec, and all programs in /bin
114: and /sbin are dynamically linked.
115: If you do not use "make build", you should ensure that
116: you have the libraries and shared linker in the new locations,
117: with:
118: make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so
1.67 lukem 119:
120: 20020917:
121: USE_NEW_TOOLCHAIN has been replaced with:
122: - TOOLCHAIN_MISSING -- set to "yes" on platforms for which
123: there is no working in-tree toolchain (hppa, ns32k, sh5,
124: x86_64).
125: - EXTERNAL_TOOLCHAIN -- if defined by the user, points to the
1.79 wiz 126: root of an external toolchain (e.g. /usr/local/gnu). This
1.67 lukem 127: enables the cross-build framework even for TOOLCHAIN_MISSING
128: platforms.
1.66 gehenna 129:
130: 20020906:
131: gehenna-devsw has been merged into the trunk. Need to update and
1.79 wiz 132: reinstall usr.sbin/config before building the kernel.
1.65 lukem 133:
134: 20020822:
135: Crunched rescue tools (contents of /bin and /sbin, plus others)
136: are now provided in /rescue.
137:
138: To ensure that these are built statically linked (no matter
139: what the setting of LDSTATIC is), use a crunchgen(1) built
140: from sources newer than 20020820 (see the next entry).
141:
142: 20020820:
143: crunchgen(1) changed to ensure that the generated program
144: is statically linked.
145:
146: Solution: update and reinstall usr.bin/crunch
1.61 itojun 147:
148: 20020515:
149: sshd user/group has been added. Need to hand add this in, or sshd
150: will not let you log in (with default, or UsePrivlegeSeparation=yes)
151:
152: Add the following into /etc/group:
153:
154: sshd:*:16:
155:
156: and the following to /etc/master.passwd (via vipw):
157:
1.63 enami 158: sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin
1.61 itojun 159:
1.79 wiz 160: Also /var/chroot/sshd directory needs to be present (digged as part of
161: the build process).
1.60 sommerfe 162:
163: 20020426:
164: NBUILDJOBS obsoleted in favor of just using -j.
1.59 lukem 165:
166: 20020426:
167: etc/postinstall added, which performs various checks for
168: configuration file updates and changes, and can fix most of
169: the problems identified.
170: This should make it much easier to upgrade a system's
171: configuration from earlier systems (as far back as NetBSD 1.5).
1.56 lukem 172:
173: 20020320:
1.79 wiz 174: <bsd.lib.mk> needs a new install(1) for its "-a cmd" support.
175: Build and install at usr.bin/xinstall before the build.
1.56 lukem 176:
1.55 itojun 177: 20020319:
1.79 wiz 178: Raw IPv6 socket now makes strict checking for sa_family and sa_len
179: on send(2) operation. Be sure to have sbin/rtsol and usr.sbin/rtsold
1.55 itojun 180: newer than November 2001 when you upgrade the kernel.
181:
1.54 itojun 182: 20020311:
183: ssh configuration files were moved from /etc to /etc/ssh. Beware
184: if you restart your machine from remote. Note that sshd.conf needs
185: to be changed (due to the use of "/etc" inside).
186:
187: 20020223:
1.53 matt 188: Users of the VAX port will need to rebuild and install gas
189: so it deal with the now present register prefix used in all
190: the VAX assembly files.
191:
1.50 itojun 192: 20020118:
193: ntpd user/group has been added. Need to hand add this in or builds
194: will break as mtree aborts early.
195:
196: Add the following into /etc/group:
197:
198: ntpd:*:15:
199:
200: and the following to /etc/master.passwd (via vipw):
201:
202: ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin
203:
1.49 jmc 204: 20011207:
205: If you're attempting to build a snapshot on sparc64 and are getting
206: reloc errors from the toolchain groff binary this means your native
207: toolchain has some broken C++ bits.
208:
209: To fix:
210:
211: Build a new toolchain (i.e. build.sh -t)
212: Use the new toolchain to build and install natively (i.e. /usr/lib)
213:
214: gnu/lib/libgcc
1.51 pooka 215: gnu/lib/libstdc++
1.49 jmc 216:
217: After this a snapshot will be able to be built.
218:
1.47 jmc 219: 20011201:
220: In order for a sparc64 build to work you must have a working awk. If
221: you've built and installed a system with the new toolchain up to this
1.52 wiz 222: point you do not have a working awk as its ability to do floating
1.47 jmc 223: point is broken.
224:
225: To build:
226:
227: remake and install gnu/lib/libgcc
228: remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links
1.48 jmc 229: against the new libgcc.a)
1.47 jmc 230:
1.46 thorpej 231: 20011128:
232: Kernel config information was changed to use defflag in
233: the various "files" files. Bug fixes to config(8) are
234: required in order for this to work properly. Make sure
235: to build and install in usr.sbin/config before attempting
236: to build a new kernel.
237:
1.45 yamt 238: 20011030:
239: libc/locale/wcstod.c now needs new lint(1). Update lint(1)
240: before building libc.
1.43 mason 241:
1.44 tv 242: 20011029:
243: The new document BUILDING.mdoc (view with nroff | more, or
244: see pre-generated .txt and .html versions) describes the build
245: procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
246: build process, are intended in the long run to replace this
247: manual update log.
248:
249: Users building a USE_NEW_TOOLCHAIN system should read the
250: BUILDING document for caveats. Generally, BUILDING supersedes
251: UPDATING for these systems, as tool updating is taken care of
252: by the new build system.
1.42 perry 253:
254: 20011028:
255: src/etc/Makefile now needs install to be able to handle
256: symlinks that point to nowhere. A bug in install that
257: prevented this was corrected.
258:
259: Solution: update and reinstall usr.bin/xinstall
260: Better Solution: Use the new toolchain and it will just work
261: for you.
1.40 lukem 262:
263: 20011006:
264: /etc/mtree/NetBSD.dist has been updated to take advantage of
265: absolute path support added to mtree(8). Older mtree(8)s don't
266: understand the format.
267:
268: Solution: update and reinstall usr.sbin/mtree
1.39 jmc 269:
270: 20011004:
271: Crunchgen has been updated to work via reach-over makefiles. Updating
272: is suggested before running a snapshot build
1.36 tv 273:
1.35 thorpej 274: 20010915:
275: The new "ubcperf" code committed by Chuck Silvers removed
276: a header file, uvm/uvm_vnode.h. There may be stale .depend
277: files that still reference this file.
278:
279: Solution: "make cleandir && make dependall" in affected
280: directories.
1.31 enami 281:
282: 20010803:
283: grep.info is now built from grep.texi using makeinfo. Since it
284: requires makeinfo v4.0, you need to install new texinfo before
285: building gnu/usr.bin/grep. To install new texinfo, please follow
286: the instruction described in 20010726 entry.
1.30 enami 287:
1.64 sommerfe 288: 20010803:
1.41 wiz 289: (i386 only): i386 kernel now uses new instructions like
290: `fxsave' which old gas doesn't understand. To build the
1.64 sommerfe 291: kernel successfully, you need to build and install a new toolchain,
292: (i.e., build.sh -t) or (temporarily) comment out "options I686_CPU"
293: from your kernel configuration until you rebuild your userland.
294: See 20011029 above and BUILDING file in this directory for more information.
295: [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]
1.29 bjh21 296:
297: 20010731:
298: Bootloader update on ELF platforms. DDB in kernels from before
299: this will be unable to read symbol tables provided by newer
300: bootloaders.
1.27 assar 301:
302: 20010726:
303: Texinfo was updated to 4.0. To avoid failures when trying to
1.28 assar 304: build the included texinfo files, do:
305:
306: cd src/gnu/usr.bin/texinfo
307: make MKINFO=no dependall install
1.25 thorpej 308:
309: 20010718:
310: Enabled correct .init/.fini processing in crt0. The way this
311: was done was to change a -I directive to cc(1), which means
312: make(1) will have a stale dependency (it will be checking the
313: timestamp on the wrong "dot_init.h").
314:
315: The symptom you will see is that new programs die with SIGSEGV
316: if you have a stale dependency.
317:
318: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
319: before starting your build.
1.26 thorpej 320:
321: 20010628:
322: A construct was added to uvm_page.h that uncovered a bug
323: in lint(1). If you get a warning/error about a non-portable
324: bitfield, update your lint(1) before proceeding.
1.21 jmc 325:
326: 20010226:
1.22 jmc 327: Added named user/group to system. Need to hand add this in or builds
1.21 jmc 328: will break as mtree aborts early.
329:
330: To work around add by hand:
331:
332: named:*:14:
333:
1.22 jmc 334: to /etc/group and add:
335:
336: named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin
337:
338: to master.passwd (use vipw for instance if doing by hand).
339:
340: Now a make build should progress.
1.18 jmc 341:
342: 20010219:
1.52 wiz 343: get/setprogname() added. Any hostprogs that may use this will need
1.20 jmc 344: to be bootstrapped manually until the host system is current.
1.18 jmc 345:
346: Known problems: sys/arch/macppc/stand/fixcoff
1.19 cgd 347: usr.sbin/config (adding -DMAKE_BOOTSTRAP to
348: CFLAGS and rebuilding should work)
1.20 jmc 349: usr.sbin/mdsetimage - Build a static copy if
350: building a snapshot before fully bootstrapped.
1.15 christos 351:
352: 20010204:
353: prepare the code to compile with stricter gcc flags. in
354: particular start eliminating redundant declarations. Yacc
355: needs to be installed before make build.
1.10 christos 356:
357: 20010114:
358: introduce .if commands(target) in make(1). You need to
359: bring everything up-to-date first, then without installing
1.23 tron 360: anything make and install in usr.bin/make, then proceed
1.10 christos 361: with make build.
1.9 sommerfe 362:
363: 20010101:
364: bsd.subdir.mk committed 20001230 had a bug which caused
365: afterinstall targets to run too soon; update again.
1.8 sommerfe 366:
367: 20001230:
368: New share/mk files needed to support .WAIT in SUBDIR variables.
369: If you get make errors,
370: (cd share/mk; make install)
371: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 372:
373: 20001019:
1.7 ad 374: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 375: major and minor numbers haven't changed, you should update your /dev
376: directory.
1.1 abs 377:
1.4 itojun 378: 20000929:
379: The following make directives are obsoleted.
380: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
381: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 382: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 383: additional library libcrypto_{idea,rc5}.
1.1 abs 384:
385:
386: Hints for a more successful build:
387: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 388: Build a new kernel first:
389: This makes sure that any new system calls or features
390: expected by the new userland will be present. This
391: helps to avoid critical errors when upgrading.
1.1 abs 392: Use object directories:
393: This helps to keep stale object
394: files from polluting the build if a Makefile "forgets"
395: about one. It also makes it easier to clean up after
396: a build. It's also necessary if you want to use the
397: same source tree for multiple machines.
398: To use object directories:
399: a) cd /usr/src ; make cleandir
1.2 mrg 400: b) Add "OBJMACHINE=yes" to /etc/mk.conf
401: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 402: d) cd /usr/src ; make build
1.2 mrg 403: Note that running "make obj" in a directory will create
404: in obj.$MACHINE directory.
1.1 abs 405: Build to a DESTDIR:
406: This helps to keep old
407: installed files (especially libraries) from interfering
408: with the new build.
409: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 410: variable before running make build. It should be set to
411: the pathname of an initially empty directory.
1.1 abs 412: Problems: you might need to update critical utilities
413: without using DESTDIR since nothing is executed
414: from what is installed in DESTDIR.
415: (See critical utils, below)
416: Build often:
417: This keeps critical utilities current enough to not choke
418: on any other part of the source tree that depends on up to
419: date functionality.
420:
421: What to do if things don't work:
422: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
423: When things don't work there is usually a few things that commonly
424: should be done.
425: 1) make includes
426: This should be done automatically by make build.
427: 2) cd share/mk && make install
428: Again, automatically done by make build.
429:
430: Failsafe rebuild of a small part of the tree:
431: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
432: To make sure you rebuild something correctly you want to do
433: something like the following:
434: 1) Make sure the includes and .mk files are up to date.
435: 2) Make sure any program used to build the particular
436: utility is up to date. (yacc, lex, etc...)
437: 3) cd ...path/to/util...
438: make cleandir
439: rm ...all obj directories...
440: make cleandir # yes, again
441: make obj
442: make depend && make
443:
444: Failsafe rebuild of the entire tree:
445: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
446: If you really want to make sure the source tree is clean and
1.2 mrg 447: ready for a build try the following. Note that sourcing /etc/mk.conf
448: (a make(1) Makefile) in this manner is not right, and will not work
449: for anyone who uses any make(1) features in /etc/mk.conf.
