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: ^^^^^^^^^^^^^^^
1.82 wiz 10:
11: 20030117:
12: Texinfo was updated to 4.3. To avoid failures when trying to
13: build the included texinfo files, do:
14:
15: cd src/gnu/usr.bin/texinfo
16: make MKINFO=no dependall install
1.81 lukem 17:
18: 20021223:
19: The METALOG format changed slightly, to remove the leading
20: "${DESTDIR}" from path names.
21: This only affects people building with UNPRIVED.
22: For complete safety, remove the DESTDIR entirely and
23: update tools/mtree, before running make build.
1.80 lukem 24:
25: 20021219:
26: install(1) had a '-N dbdir' option added, to specify an
27: alternate location to look up users & groups (instead
28: of the host system passwd(5) and group(5) databases).
29:
30: The build system was modified to take advantage of
31: this option (using ${NETBSDSRCDIR}/etc), so if you
1.83 kei 32: use USETOOLS==no, you may have to rebuild and
1.80 lukem 33: reinstall usr.bin/xinstall first.
1.78 lukem 34:
35: 20021130:
36: fparseln(3) moved from libutil to libc.
37: If building to DESTDIR=/, reinstall the includes
38: and rebuild libc:
39: make includes
40: make do-lib-libc
41: If using build.sh, "cd tools/compat && make clean"
42: before rebuilding the tools.
1.77 lukem 43:
44: 20021126:
45: The mk.conf(5) variable SYS_INCLUDE has been deprecated,
46: including the optional "SYS_INCLUDE=symlinks" support.
47: All header files, including <sys/*.h> are copied into
48: /usr/include.
1.76 thorpej 49:
50: 20021121:
51: The C run-time support files crtbegin.o and crtend.o
52: (and their companions crtbeginS.o and crtendS.o) were
53: split up, with new crti.o and crtn.o files resulting.
54: This means that libtool needs to be rebuilt once the
55: new libraries are installed. The process of rebuilding
56: libtool will cause it to automatically notice the new
57: required files, but it *must* be rebuilt in order to
58: do this.
59:
60: An out-of-date libtool will result in shared libraries
61: which lack _init() and _fini() routines, which means that
62: their global contructors/destructors will not be invoked.
1.75 thorpej 63:
64: 20021121:
65: A bug related to how ARM ELF objects were tagged has been
66: corrected.
67:
68: NetBSD ARM ELF uses the soft-VFP floating point model by
69: default. However, the assembler lacked support for marking
70: objects as using the VFP floating point format, and the
1.79 wiz 71: compiler was not properly passing the flag indicating "soft-VFP"
1.75 thorpej 72: to the assembler.
73:
74: Unfortunately, this means that the linker will now consider
75: old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be
76: incompatible with new (properly marked) objects.
77:
78: The problem will only manifest itself if you attempt to compile
79: a new program using the fixed toolchain, and link that program
80: against old libraries which do not have the proper "softvfp"
81: markings. ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES
82: WILL CONTINUE TO WORK PROPERLY.
83:
84: The only work-around for the problem is to recompile all of
85: the libraries on the system. The easiest way to do this for
1.79 wiz 86: system libraries is to install a binary snapshot; they are
1.75 thorpej 87: generally available on releng.netbsd.org. Any packages you
88: have installed which supply libraries will have to be recompiled
89: if you wish to link new programs against those libraries.
90:
91: If you have questions about this matter, please contact
92: port-arm@netbsd.org.
1.73 provos 93:
94: 20021011:
95: Systrace has been improved to support privilege elevation.
96: Updating the kernel requires the userland part of systrace
1.79 wiz 97: to be rebuilt.
1.72 thorpej 98:
99: 20021010:
100: The config(8) grammar was changed to allow options to register
101: dependencies on attributes, as well as other options. Users
102: must update and reinstall usr.sbin/config before building a new
103: kernel.
1.70 thorpej 104:
105: 20021009:
106: A new attribute dependency syntax was introduced to config(8),
107: which is now used by the SCSI configuration description. Users
1.71 wiz 108: must update and reinstall usr.sbin/config before building a new
1.70 thorpej 109: kernel.
1.69 thorpej 110:
111: 20021003:
112: Several changes have been made to the autoconfiguration
113: framework. Users must update and reinstall usr.sbin/config
114: before building a new kernel.
1.74 jschauma 115:
116: 20021001:
117: The i386mp branch has been merged. To compile a kernel, users
118: will need to add the option 'cpu* at mainbus?' to their configuration
119: file. Multiprocessor kernels will need
120: ioapic* at mainbus? apid ?
121: options MULTIPROCESSOR
122: options COM_MPLOCK
1.68 lukem 123:
124: 20020922:
125: MKDYNAMICROOT=yes enabled by default, which means that
126: certain shared libraries are installed into /lib, the shared
127: linker is installed into /libexec, and all programs in /bin
128: and /sbin are dynamically linked.
129: If you do not use "make build", you should ensure that
130: you have the libraries and shared linker in the new locations,
131: with:
132: make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so
1.67 lukem 133:
134: 20020917:
135: USE_NEW_TOOLCHAIN has been replaced with:
136: - TOOLCHAIN_MISSING -- set to "yes" on platforms for which
137: there is no working in-tree toolchain (hppa, ns32k, sh5,
138: x86_64).
139: - EXTERNAL_TOOLCHAIN -- if defined by the user, points to the
1.79 wiz 140: root of an external toolchain (e.g. /usr/local/gnu). This
1.67 lukem 141: enables the cross-build framework even for TOOLCHAIN_MISSING
142: platforms.
1.66 gehenna 143:
144: 20020906:
145: gehenna-devsw has been merged into the trunk. Need to update and
1.79 wiz 146: reinstall usr.sbin/config before building the kernel.
1.65 lukem 147:
148: 20020822:
149: Crunched rescue tools (contents of /bin and /sbin, plus others)
150: are now provided in /rescue.
151:
152: To ensure that these are built statically linked (no matter
153: what the setting of LDSTATIC is), use a crunchgen(1) built
154: from sources newer than 20020820 (see the next entry).
155:
156: 20020820:
157: crunchgen(1) changed to ensure that the generated program
158: is statically linked.
159:
160: Solution: update and reinstall usr.bin/crunch
1.84 ! grant 161:
! 162: 20020605:
! 163: smmsp user/group has been added for sendmail.
! 164:
! 165: Add the following into /etc/group:
! 166:
! 167: smmsp:*:17:
! 168:
! 169: and the following to /etc/master.passwd (via vipw):
! 170:
! 171: smmsp:*:17:17::0:0:Sendmail Message Submission Program:/nonexistent:/sbin/nologin
1.61 itojun 172:
173: 20020515:
174: sshd user/group has been added. Need to hand add this in, or sshd
175: will not let you log in (with default, or UsePrivlegeSeparation=yes)
176:
177: Add the following into /etc/group:
178:
179: sshd:*:16:
180:
181: and the following to /etc/master.passwd (via vipw):
182:
1.63 enami 183: sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin
1.61 itojun 184:
1.79 wiz 185: Also /var/chroot/sshd directory needs to be present (digged as part of
186: the build process).
1.60 sommerfe 187:
188: 20020426:
189: NBUILDJOBS obsoleted in favor of just using -j.
1.59 lukem 190:
191: 20020426:
192: etc/postinstall added, which performs various checks for
193: configuration file updates and changes, and can fix most of
194: the problems identified.
195: This should make it much easier to upgrade a system's
196: configuration from earlier systems (as far back as NetBSD 1.5).
1.56 lukem 197:
198: 20020320:
1.79 wiz 199: <bsd.lib.mk> needs a new install(1) for its "-a cmd" support.
200: Build and install at usr.bin/xinstall before the build.
1.56 lukem 201:
1.55 itojun 202: 20020319:
1.79 wiz 203: Raw IPv6 socket now makes strict checking for sa_family and sa_len
204: on send(2) operation. Be sure to have sbin/rtsol and usr.sbin/rtsold
1.55 itojun 205: newer than November 2001 when you upgrade the kernel.
206:
1.54 itojun 207: 20020311:
208: ssh configuration files were moved from /etc to /etc/ssh. Beware
209: if you restart your machine from remote. Note that sshd.conf needs
210: to be changed (due to the use of "/etc" inside).
211:
212: 20020223:
1.53 matt 213: Users of the VAX port will need to rebuild and install gas
214: so it deal with the now present register prefix used in all
215: the VAX assembly files.
216:
1.50 itojun 217: 20020118:
218: ntpd user/group has been added. Need to hand add this in or builds
219: will break as mtree aborts early.
220:
221: Add the following into /etc/group:
222:
223: ntpd:*:15:
224:
225: and the following to /etc/master.passwd (via vipw):
226:
227: ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin
228:
1.49 jmc 229: 20011207:
230: If you're attempting to build a snapshot on sparc64 and are getting
231: reloc errors from the toolchain groff binary this means your native
232: toolchain has some broken C++ bits.
233:
234: To fix:
235:
236: Build a new toolchain (i.e. build.sh -t)
237: Use the new toolchain to build and install natively (i.e. /usr/lib)
238:
239: gnu/lib/libgcc
1.51 pooka 240: gnu/lib/libstdc++
1.49 jmc 241:
242: After this a snapshot will be able to be built.
243:
1.47 jmc 244: 20011201:
245: In order for a sparc64 build to work you must have a working awk. If
246: you've built and installed a system with the new toolchain up to this
1.52 wiz 247: point you do not have a working awk as its ability to do floating
1.47 jmc 248: point is broken.
249:
250: To build:
251:
252: remake and install gnu/lib/libgcc
253: remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links
1.48 jmc 254: against the new libgcc.a)
1.47 jmc 255:
1.46 thorpej 256: 20011128:
257: Kernel config information was changed to use defflag in
258: the various "files" files. Bug fixes to config(8) are
259: required in order for this to work properly. Make sure
260: to build and install in usr.sbin/config before attempting
261: to build a new kernel.
262:
1.45 yamt 263: 20011030:
264: libc/locale/wcstod.c now needs new lint(1). Update lint(1)
265: before building libc.
1.43 mason 266:
1.44 tv 267: 20011029:
268: The new document BUILDING.mdoc (view with nroff | more, or
269: see pre-generated .txt and .html versions) describes the build
270: procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
271: build process, are intended in the long run to replace this
272: manual update log.
273:
274: Users building a USE_NEW_TOOLCHAIN system should read the
275: BUILDING document for caveats. Generally, BUILDING supersedes
276: UPDATING for these systems, as tool updating is taken care of
277: by the new build system.
1.42 perry 278:
279: 20011028:
280: src/etc/Makefile now needs install to be able to handle
281: symlinks that point to nowhere. A bug in install that
282: prevented this was corrected.
283:
284: Solution: update and reinstall usr.bin/xinstall
285: Better Solution: Use the new toolchain and it will just work
286: for you.
1.40 lukem 287:
288: 20011006:
289: /etc/mtree/NetBSD.dist has been updated to take advantage of
290: absolute path support added to mtree(8). Older mtree(8)s don't
291: understand the format.
292:
293: Solution: update and reinstall usr.sbin/mtree
1.39 jmc 294:
295: 20011004:
296: Crunchgen has been updated to work via reach-over makefiles. Updating
297: is suggested before running a snapshot build
1.36 tv 298:
1.35 thorpej 299: 20010915:
300: The new "ubcperf" code committed by Chuck Silvers removed
301: a header file, uvm/uvm_vnode.h. There may be stale .depend
302: files that still reference this file.
303:
304: Solution: "make cleandir && make dependall" in affected
305: directories.
1.31 enami 306:
307: 20010803:
308: grep.info is now built from grep.texi using makeinfo. Since it
309: requires makeinfo v4.0, you need to install new texinfo before
310: building gnu/usr.bin/grep. To install new texinfo, please follow
311: the instruction described in 20010726 entry.
1.30 enami 312:
1.64 sommerfe 313: 20010803:
1.41 wiz 314: (i386 only): i386 kernel now uses new instructions like
315: `fxsave' which old gas doesn't understand. To build the
1.64 sommerfe 316: kernel successfully, you need to build and install a new toolchain,
317: (i.e., build.sh -t) or (temporarily) comment out "options I686_CPU"
318: from your kernel configuration until you rebuild your userland.
319: See 20011029 above and BUILDING file in this directory for more information.
320: [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]
1.29 bjh21 321:
322: 20010731:
323: Bootloader update on ELF platforms. DDB in kernels from before
324: this will be unable to read symbol tables provided by newer
325: bootloaders.
1.27 assar 326:
327: 20010726:
328: Texinfo was updated to 4.0. To avoid failures when trying to
1.28 assar 329: build the included texinfo files, do:
330:
331: cd src/gnu/usr.bin/texinfo
332: make MKINFO=no dependall install
1.25 thorpej 333:
334: 20010718:
335: Enabled correct .init/.fini processing in crt0. The way this
336: was done was to change a -I directive to cc(1), which means
337: make(1) will have a stale dependency (it will be checking the
338: timestamp on the wrong "dot_init.h").
339:
340: The symptom you will see is that new programs die with SIGSEGV
341: if you have a stale dependency.
342:
343: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
344: before starting your build.
1.26 thorpej 345:
346: 20010628:
347: A construct was added to uvm_page.h that uncovered a bug
348: in lint(1). If you get a warning/error about a non-portable
349: bitfield, update your lint(1) before proceeding.
1.21 jmc 350:
351: 20010226:
1.22 jmc 352: Added named user/group to system. Need to hand add this in or builds
1.21 jmc 353: will break as mtree aborts early.
354:
355: To work around add by hand:
356:
357: named:*:14:
358:
1.22 jmc 359: to /etc/group and add:
360:
361: named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin
362:
363: to master.passwd (use vipw for instance if doing by hand).
364:
365: Now a make build should progress.
1.18 jmc 366:
367: 20010219:
1.52 wiz 368: get/setprogname() added. Any hostprogs that may use this will need
1.20 jmc 369: to be bootstrapped manually until the host system is current.
1.18 jmc 370:
371: Known problems: sys/arch/macppc/stand/fixcoff
1.19 cgd 372: usr.sbin/config (adding -DMAKE_BOOTSTRAP to
373: CFLAGS and rebuilding should work)
1.20 jmc 374: usr.sbin/mdsetimage - Build a static copy if
375: building a snapshot before fully bootstrapped.
1.15 christos 376:
377: 20010204:
378: prepare the code to compile with stricter gcc flags. in
379: particular start eliminating redundant declarations. Yacc
380: needs to be installed before make build.
1.10 christos 381:
382: 20010114:
383: introduce .if commands(target) in make(1). You need to
384: bring everything up-to-date first, then without installing
1.23 tron 385: anything make and install in usr.bin/make, then proceed
1.10 christos 386: with make build.
1.9 sommerfe 387:
388: 20010101:
389: bsd.subdir.mk committed 20001230 had a bug which caused
390: afterinstall targets to run too soon; update again.
1.8 sommerfe 391:
392: 20001230:
393: New share/mk files needed to support .WAIT in SUBDIR variables.
394: If you get make errors,
395: (cd share/mk; make install)
396: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 397:
398: 20001019:
1.7 ad 399: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 400: major and minor numbers haven't changed, you should update your /dev
401: directory.
1.1 abs 402:
1.4 itojun 403: 20000929:
404: The following make directives are obsoleted.
405: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
406: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 407: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 408: additional library libcrypto_{idea,rc5}.
1.1 abs 409:
410:
411: Hints for a more successful build:
412: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 413: Build a new kernel first:
414: This makes sure that any new system calls or features
415: expected by the new userland will be present. This
416: helps to avoid critical errors when upgrading.
1.1 abs 417: Use object directories:
418: This helps to keep stale object
419: files from polluting the build if a Makefile "forgets"
420: about one. It also makes it easier to clean up after
421: a build. It's also necessary if you want to use the
422: same source tree for multiple machines.
423: To use object directories:
424: a) cd /usr/src ; make cleandir
1.2 mrg 425: b) Add "OBJMACHINE=yes" to /etc/mk.conf
426: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 427: d) cd /usr/src ; make build
1.2 mrg 428: Note that running "make obj" in a directory will create
429: in obj.$MACHINE directory.
1.1 abs 430: Build to a DESTDIR:
431: This helps to keep old
432: installed files (especially libraries) from interfering
433: with the new build.
434: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 435: variable before running make build. It should be set to
436: the pathname of an initially empty directory.
1.1 abs 437: Problems: you might need to update critical utilities
438: without using DESTDIR since nothing is executed
439: from what is installed in DESTDIR.
440: (See critical utils, below)
441: Build often:
442: This keeps critical utilities current enough to not choke
443: on any other part of the source tree that depends on up to
444: date functionality.
445:
446: What to do if things don't work:
447: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
448: When things don't work there is usually a few things that commonly
449: should be done.
450: 1) make includes
451: This should be done automatically by make build.
452: 2) cd share/mk && make install
453: Again, automatically done by make build.
454:
455: Failsafe rebuild of a small part of the tree:
456: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
457: To make sure you rebuild something correctly you want to do
458: something like the following:
459: 1) Make sure the includes and .mk files are up to date.
460: 2) Make sure any program used to build the particular
461: utility is up to date. (yacc, lex, etc...)
462: 3) cd ...path/to/util...
463: make cleandir
464: rm ...all obj directories...
465: make cleandir # yes, again
466: make obj
467: make depend && make
468:
469: Failsafe rebuild of the entire tree:
470: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
471: If you really want to make sure the source tree is clean and

1.1 abs 511: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
512: Symptom:Unreasonable compiler errors.
513: Fix: Rebuild gnu/usr.bin/egcs
514:
515: Symptom:Complaints involving a Makefile.
1.17 erh 516: Fix: Rebuild usr.bin/make:
517: cd usr.bin/make && make && make install
518: Or, a failsafe method if that doesn't work:
519: cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
520:
1.1 abs 521: Fix: Make sure .mk files are up to date.
522: cd share/mk && make install

536: Symptom:Obsolete intermediate files are used during compilation
537: Fix: Try the following sequence of commands in the directory in question.
538: make cleandir; rm `make print-objdir`; make cleandir; make obj
539: (If you built the tree without "make obj" in the past, obsolete files
540: may remain. The command tries to clean everything up)
