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36: An out-of-date libtool will result in shared libraries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