1.1 abs 2:
1.123 jmc 3: This file (UPDATING) is intended to be a brief reference to recent
4: changes that might cause problems in the build process, and a guide for
5: what to do if something doesn't work.
1.1 abs 6:
1.123 jmc 7: For a more detailed description of the recommended way to build NetBSD
8: using build.sh, see the BUILDING file.
9:
10: Note that much of the advice in this UPDATING file was written before
11: build.sh existed. Nevertheless, the advice here may be useful for
12: working around specific problems with build.sh.

17: ^^^^^^^^^^^^^^^
1.138 lukem 18:
1.146 ! pavel 19: 20060526:
! 20: the kernel links script for i386 and xen was changed to set the
! 21: load address correctly, for the benefit of MULTIBOOT boot loaders
! 22: (like Grub). If you use a linker (ld) older than from 2006/04/17, it
! 23: will be unable to link the kernel because of a bug, and you will
! 24: have to update at least src/gnu/dist/binutils/ld and recompile the
! 25: linker. If using the build.sh script, the easiest way is with a
! 26: "build.sh tools" command, with any other options that you use
! 27: normally. When using build.sh, the linker binary is installed as
! 28: ${TOOLDIR}/bin/i386--netbsdelf-ld.
1.145 martin 29: 20060131:
30: the protocol between the sparc64 bootloader (ofwboot) and
31: the kernel was changed. Before installing a new kernel,
32: you need to update ofwboot. After a full build, just copy
33: /usr/mdec/ofwboot to /, or do a rebuild of
34: src/sys/arch/sparc/stand/ofwboot and install the result to /.
35:
1.144 yamt 36: 20050917:
37: arch/*/conf/std.* was changed to include conf/std, which
38: contains MI options previously enabled by default.
39: If you have kernel config files which doesn't include
40: arch/*/conf/std.*, you need to edit them to include conf/std
41: to get the previous configuration.
42:
1.143 lukem 43: 20050830:
44: named.conf was moved from /etc/namedb to /etc.
45: postinstall(8) migrates this during interactive use.
46: Users of MKUPDATE=yes will need to manually rectify
47: this in their DESTDIR.
48:
1.142 drochner 49: 20050825:
50: Some data structures in sys/device.h, related to interface
51: attributes and locator names, were changed. config(1) was
52: modified to emit the new data structures.
53: Thus usr.bin/config must be updated (and run on the kernel
54: configuration file) before a new kernel can be built.
55:
1.139 christos 56: 20050531:
1.141 augustss 57: genassym.sh(8) was moved to genassym(1). You need to either build
58: tools first or install the version of genassym from /usr/bin before
1.139 christos 59: you can build a kernel again.
60:
1.140 yamt 61: 20050520:
62: Because a kernfs bug which xentools relies on was fixed,
63: xentools up to xentools20-2.0.3nb4 won't work with new kernel.
64:
1.138 lukem 65: 20050417:
66: postinstall(8) was moved from /etc to /usr/sbin and made part
67: of the "base" set, to make it easier to invoke after an
68: upgrade.
69:
1.136 cube 70: 20050325:
71: pcppi(4) was separated in two devices, adding attimer(4). Be sure
72: to add a config line for an attimer(4) device in your kernel
73: configuration, or you won't be able to set the pitch of the beep
1.137 cube 74: with wsconsctl. Depending on the default value for the pitch, you
75: might even not hear any more beep. Also, it is advised to attach both
76: devices the same way (i.e., both on isa or both on acpi) or the
77: pcppi(4) device may fail to find the attimer(4) one.
1.136 cube 78:
1.135 jmc 79: 20050211:
80: Fixes to tools/Makefile.gnuhost may cause UPDATE=1 builds in
81: some of the cross tools to fail if they use configure. Some configure's
82: cache the environment passed in and notice the new environment is
83: different and abort. Doing a clean in tools/ should be enough to
84: make a build continue.
85:
1.134 christos 86: 20050109:
87: Since su is using pam by default now, make sure that you have
88: /etc/pam.d populated (postinstall will do that automatically
89: for you). Otherwise su will fail open (i.e. will not require
90: a password).
91:
1.133 christos 92: 20041229:
93: Make had a path resolution bug that manifested itself as not
94: being able to install openpam.3. This bug has been fixed, but
95: you might need to rebuild make manually first to get through
96: the build.
97:
1.130 christos 98: 20041201:
99: Userland programs have been changed to use /dev/bpf instead of
100: /dev/bpfX. You need to create that device by installing a new
1.131 wiz 101: MAKEDEV and running it, or mv /dev/bpf0 /dev/bpf && rm /dev/bpf[0-9]*
1.99 mrg 102:
1.129 jmc 103: 20041006:
104:
105: A bug was introduced into /bin/sh (var.c rev 1.35) which causes
106: variables to not export correctly to subshells in all cases. This
107: will cause builds to break if that version of /bin/sh is installed
108: on the system. The proper version of /bin/sh can be verified with:
109:
110: ident /bin/sh | grep var
111:
112: Any /bin/sh w. version 1.35 will not work and needs to be updated
113: before attempting a build.
114:
1.127 christos 115: 20041001:
116: The ipfilter kernel sources moved from sys/netinet to
117: dist/sys/ipf/netinet. Due to the move some Makefile
118: dependencies are now dangling requiring a make cleandir
1.128 he 119: before they work again (kdump, ktruss, rescue, ipf, and
120: ftp-proxy are the victims).
1.127 christos 121:
1.125 atatat 122: 20040715:
123: The rc.d/sendmail script now uses a heuristic to determine
124: if sendmail should be started at boot time. It checks the
125: contents of /etc/mailer.conf, /etc/mail/submit.cf, and the
126: owner and mode of the sendmail binary to see if any changes
127: to the mail infrastructure have been made. If no changes
128: are detected, it will start an SMTP listener.
129:
130: Setting sendmail=NO in /etc/rc.conf will override this.
131:
132: If you are only using sendmail by default and only for
133: local delivery, it is important that you also update your
134: sendmail.cf so that the SMTP listener only listens on the
135: loopback interface.
136:
137: 20040715:
138: The method by which athhal-elf.o gets pulled into i386
139: kernel builds has been changed again. The latest version
140: of bsd.files.mk is no longer required.
141:
1.124 jmc 142: 20040621:
143: Due to the recent rototill of tools/compat it's crucial one starts
144: from a clean objdir under tools/*.
145:
146: This is mostly due to generated files (yacc and lex sources) needing
1.125 atatat 147: to be generated with new rules from bsd.hostprog.mk.
1.124 jmc 148:
149: The safest course is to rm -rf all objects under tools before building.
150:
1.121 lukem 151: 20040516:
152: The end-user modifiable X11 configuration has been moved
153: from /usr/X11R6/lib/X11/<dir> to /etc/X11/<dir>.
154: Ensure that src and xsrc is up to date, and run
155: "make cleandir" in src/x11 before your next build.
156:
1.126 lukem 157: postinstall currently doesn't migrate the files from
158: /usr/X11R6/lib/X11/* to /etc/X11/* although it does
159: detect that this needs to occur, so you'll have to
160: manually move these files yourself.
161:
1.119 atatat 162: 20040426:
163: Support for the original dynamic sysctl node structure has
164: been removed in favor of the newer layout. This affects
165: consumers of the create and delete interface, as well as
166: the dynamic discovery mechanism. This is believed only to
167: be the sysctl(8) binary itself, at this point in time, so
168: the only effect of this should be that a sysctl binary
169: built from sources dated between 2003/12/04 and 2004/03/24
170: will not work on a kernel built from sources dated after
171: 2004/04/25. If you need a new sysctl binary but build.sh
172: does not work, make sure that your revision of
1.120 atatat 173: src/sys/sys/sysctl.h is 1.112 (or later), and then the
174: do the following:
1.119 atatat 175:
1.120 atatat 176: cd /usr/src (or wherever your source tree is)
177: make USETOOLS=no includes
178: cd lib/libc
179: make USETOOLS=no dependall install
180: cd ../../sbin/sysctl
1.119 atatat 181: make USETOOLS=no dependall install
182:
1.122 itojun 183: If you are using older sysctl binary, GNU autoconf would fail to
184: identify your machine architecture, and tries to build binary for
185: "unknown-unknown-netbsd20F" or something like that. if that happens,
186: make sure to follow the above steps.
187:
1.118 dbj 188: 20040425:
189: The ffs superblock issues listed below under 20040109 and 20030402
190: are now automatically addressed by the /etc/rc.d/fixsb script or by
191: sysinst when it checks a a filesystem. The manual fsck_ffs -b16 -c4
192: invocation mentioned below will continue to work and is now
193: automated by those scripts. Note that under certain circumstances,
194: affected filesystems upgraded to a -current kernel first before
195: upgrading their userland with the fixsb and fsck_ffs fixes may
196: encounter a 'freeing free inode' panic when writing to the affected
197: filesystem, so it is a good idea to repair the filesystem as soon as
198: possible. For more details on the fixsb script, see pr install/25138.
199:
1.115 christos 200: 20040418:
1.121 lukem 201: statfs(2) and friends have been replaced with statvfs(2). Before
1.115 christos 202: installing a newly build userland make sure that you are running
203: a newly built kernel with COMPAT_20 set. In addition your libc
204: build might not work (undefined SYS_statfs symbol) because make
205: clean does not know how to remove files it does not know about
1.116 christos 206: anymore. Manually remove all generated .S sources and objects
207: from the libc build directory.
1.115 christos 208:
1.114 jmc 209: 20040326:
210: The method by which athhal-elf.o gets pulled into i386 kernel builds
1.117 jmc 211: has been changed. The file is now stored as a uuencoded file in CVS
1.114 jmc 212: and the generated Makefile will use the new .uue rules from bsd.file.mk
213: to build it.
214:
215: This means you must have the latest bsd.files.mk installed when
216: building a kernel without USETOOLS=yes.
217:
1.113 dan 218: 20040318:
219: A bug in the cgd(4) blowfish code was corrected, without
220: provision of backwards compatibility, after several public
221: notices over several months. Users of cgd with blowfish cipher
222: ONLY must dump their data before updating their kernels, and
223: recreate cgd's and restore data using the new kernel. See
224: (recent message to current-users, URL when mail-index has updated)
225:
1.108 bjh21 226: 20040313:
227: On acorn32, the opms and qms drivers have been withdrawn, and
228: the old wsqms driver is now called qms. Kernel config files
229: will need updating. See the ones in sys/arch/acorn32/conf
230: for examples.
231:
1.106 bjh21 232: 20040125:
233: On acorn32, the beep and sysbeep devices are no longer
234: needed, and will need to be deleted from kernel configuration
235: files.
1.105 bjh21 236:
1.102 dbj 237: 20040109:
238: Compatibility for old ffs superblock layouts has been
239: added, and the restrictive fsck checks have been reenabled
240: when using those layouts. If you have been using -current
241: since 20030402, you may find that fsck again signals fatal
1.110 dbj 242: superblock mismatches. To repair, make sure you have
1.111 simonb 243: an updated fsck_ffs and then you can use fsck_ffs -b 16 -c 4
1.109 dbj 244: to complete the filesystem upgrade. A message has
1.111 simonb 245: been added to the kernel which should detect this problem.
246: See the following discussion for more information:
1.112 keihan 247: http://mail-index.NetBSD.org/current-users/2004/01/11/0022.html
1.102 dbj 248:
1.99 mrg 249: 20031203:
1.100 keihan 250: New binutils builds may fail due to old dependencies.
1.99 mrg 251: It's necessary to "make cleandir" to ensure that
252: the dependencies will be rebuilt correctly.
1.98 wiz 253:
254: 20031111:
255: A newer mkdep is needed. Error noting that is
256: cc: Ambiguous abbreviation --
1.97 lukem 257:
258: 20031008:
259: /usr/include/sys/disklabel_mbr.h was removed.
260: It's necessary to "make cleandir" to ensure that
261: the dependencies will be rebuilt correctly.
1.96 christos 262:
1.109 dbj 263: 20031007:
1.111 simonb 264: A sign exension bug was fixed which set all the high bits
265: of our newly expanded ffs fs_flags. This should only
266: affect users who installed or upgraded in September of 2003.
1.109 dbj 267: A small utility program was posted to tech-kern which
1.111 simonb 268: should fix this problem, and a warning message was added
269: to the kernel which should discover and warn about it. See
270: http://mail-index.NetBSD.org/tech-kern/2003/10/07/0005.html
1.109 dbj 271:
1.96 christos 272: 20030906:
273: With the addition of siginfo support the old signal trampoline
274: code has been deprecated to COMPAT_16. Make sure that your running
275: kernel has COMPAT_16 enabled before building userland.
1.94 christos 276:
277: 20030801:
1.95 wiz 278: With the new openssl, there is some header and library shuffling.
1.94 christos 279: rm -f /usr/include/des.h /usr/include/kerberosIV/* /lib/libdes* \
1.95 wiz 280: /usr/lib/libdes* before building.
1.92 wiz 281:
282: 20030703:
283: Texinfo was updated to 4.6. To avoid failures when trying to
284: build the included texinfo files, do:
285:
286: cd src/gnu/usr.bin/texinfo
287: make MKINFO=no dependall install
1.90 wiz 288:
289: 20030630:
1.101 junyoung 290: Groff was updated to 1.19; it's probably necessary to do
1.91 wiz 291: cd share/mk && make install
1.90 wiz 292: cd src/gnu/usr.bin/groff
293: make MKMAN=no dependall install
294: (untested).
1.89 christos 295:
296: 20030516:
297: Due to bugs in the export handling code, invalid export lines
298: were accepted before and caused the kernel to panic when
299: mountd got restarted because it freed memory that had already
300: been freed. This has been fixed and the kernel checks
301: export addresses very strictly. If you upgrade your kernel,
302: make sure you also upgrade mountd, because if your export
303: file contains lines with an old inet4 address syntax (i.e.
304: a.b.c or a.b or a), they will get rejected by the new kernel.
1.87 bjh21 305:
306: 20030402:
307: The superblock layout for FFS was changed. If you have 1.6
308: fsck binaries, they will signal a fatal superblock mismatch
309: with the first alternate, because they compare too many
310: fields (even ones that aren't useful). If possible, upgrade
311: your fsck_ffs binary before using a new kernel.
312: None of this signals actual filesystem damage.
1.85 atatat 313:
314: 20030324:
315: sendmail version 8.12.8 was imported. Since sendmail is
316: now setgid to the smmsp group, and runs in "collection"
317: mode for most common activities, there is a new config
318: file called submit.cf that needs to live in /etc/mail.
319: The generic submit.cf sample in /usr/share/sendmail/cf
320: is named netbsd-msp.cf. Upgrading your regular sendmail
321: configuration file is also strongly advised.
322:
323: See the section named "MESSAGE SUBMISSION PROGRAM" in
324: the updated /usr/share/sendmail/README file for more
325: information.
1.82 wiz 326:
327: 20030117:
328: Texinfo was updated to 4.3. To avoid failures when trying to
329: build the included texinfo files, do:
330:
331: cd src/gnu/usr.bin/texinfo
332: make MKINFO=no dependall install
1.81 lukem 333:
334: 20021223:
335: The METALOG format changed slightly, to remove the leading
336: "${DESTDIR}" from path names.
337: This only affects people building with UNPRIVED.
338: For complete safety, remove the DESTDIR entirely and
339: update tools/mtree, before running make build.
1.88 itojun 340:
341: 20021219:
342: CVS repository layout was changed. See the following for details
343: if you are using (anonymous) cvs to update your tree.
344:
1.93 salo 345: http://mail-index.NetBSD.org/netbsd-announce/2002/12/19/0000.html
1.80 lukem 346:
347: 20021219:
348: install(1) had a '-N dbdir' option added, to specify an
349: alternate location to look up users & groups (instead
350: of the host system passwd(5) and group(5) databases).
351:
352: The build system was modified to take advantage of
353: this option (using ${NETBSDSRCDIR}/etc), so if you
1.83 kei 354: use USETOOLS==no, you may have to rebuild and
1.80 lukem 355: reinstall usr.bin/xinstall first.
1.78 lukem 356:
357: 20021130:
358: fparseln(3) moved from libutil to libc.
359: If building to DESTDIR=/, reinstall the includes
360: and rebuild libc:
361: make includes
362: make do-lib-libc
363: If using build.sh, "cd tools/compat && make clean"
364: before rebuilding the tools.
1.77 lukem 365:
366: 20021126:
367: The mk.conf(5) variable SYS_INCLUDE has been deprecated,
368: including the optional "SYS_INCLUDE=symlinks" support.
369: All header files, including <sys/*.h> are copied into
370: /usr/include.
1.76 thorpej 371:
372: 20021121:
373: The C run-time support files crtbegin.o and crtend.o
374: (and their companions crtbeginS.o and crtendS.o) were
375: split up, with new crti.o and crtn.o files resulting.
376: This means that libtool needs to be rebuilt once the
377: new libraries are installed. The process of rebuilding
378: libtool will cause it to automatically notice the new
379: required files, but it *must* be rebuilt in order to
380: do this.
381:
382: An out-of-date libtool will result in shared libraries
383: which lack _init() and _fini() routines, which means that
384: their global contructors/destructors will not be invoked.
1.75 thorpej 385:
386: 20021121:
387: A bug related to how ARM ELF objects were tagged has been
388: corrected.
389:
390: NetBSD ARM ELF uses the soft-VFP floating point model by
391: default. However, the assembler lacked support for marking
392: objects as using the VFP floating point format, and the
1.79 wiz 393: compiler was not properly passing the flag indicating "soft-VFP"
1.75 thorpej 394: to the assembler.
395:
396: Unfortunately, this means that the linker will now consider
397: old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be
398: incompatible with new (properly marked) objects.
399:
400: The problem will only manifest itself if you attempt to compile
401: a new program using the fixed toolchain, and link that program
402: against old libraries which do not have the proper "softvfp"
403: markings. ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES
404: WILL CONTINUE TO WORK PROPERLY.
405:
406: The only work-around for the problem is to recompile all of
407: the libraries on the system. The easiest way to do this for
1.79 wiz 408: system libraries is to install a binary snapshot; they are
1.93 salo 409: generally available on releng.NetBSD.org. Any packages you
1.75 thorpej 410: have installed which supply libraries will have to be recompiled
411: if you wish to link new programs against those libraries.
412:
413: If you have questions about this matter, please contact
1.93 salo 414: port-arm@NetBSD.org.
1.73 provos 415:
416: 20021011:
417: Systrace has been improved to support privilege elevation.
418: Updating the kernel requires the userland part of systrace
1.79 wiz 419: to be rebuilt.
1.72 thorpej 420:
421: 20021010:
422: The config(8) grammar was changed to allow options to register
423: dependencies on attributes, as well as other options. Users
424: must update and reinstall usr.sbin/config before building a new
425: kernel.
1.70 thorpej 426:
427: 20021009:
428: A new attribute dependency syntax was introduced to config(8),

435: framework. Users must update and reinstall usr.sbin/config
436: before building a new kernel.
1.74 jschauma 437:
438: 20021001:
439: The i386mp branch has been merged. To compile a kernel, users
440: will need to add the option 'cpu* at mainbus?' to their configuration
441: file. Multiprocessor kernels will need
442: ioapic* at mainbus? apid ?
443: options MULTIPROCESSOR
444: options COM_MPLOCK
1.68 lukem 445:
446: 20020922:
447: MKDYNAMICROOT=yes enabled by default, which means that
448: certain shared libraries are installed into /lib, the shared
449: linker is installed into /libexec, and all programs in /bin
450: and /sbin are dynamically linked.
451: If you do not use "make build", you should ensure that
452: you have the libraries and shared linker in the new locations,
453: with:
454: make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so
1.67 lukem 455:

457: USE_NEW_TOOLCHAIN has been replaced with:
458: - TOOLCHAIN_MISSING -- set to "yes" on platforms for which
459: there is no working in-tree toolchain (hppa, ns32k, sh5,
460: x86_64).
461: - EXTERNAL_TOOLCHAIN -- if defined by the user, points to the
1.79 wiz 462: root of an external toolchain (e.g. /usr/local/gnu). This
1.67 lukem 463: enables the cross-build framework even for TOOLCHAIN_MISSING
464: platforms.
1.66 gehenna 465:

472: are now provided in /rescue.
473:
474: To ensure that these are built statically linked (no matter
475: what the setting of LDSTATIC is), use a crunchgen(1) built
476: from sources newer than 20020820 (see the next entry).

511: NBUILDJOBS obsoleted in favor of just using -j.
1.59 lukem 512:

514: etc/postinstall added, which performs various checks for
515: configuration file updates and changes, and can fix most of
516: the problems identified.
517: This should make it much easier to upgrade a system's
518: configuration from earlier systems (as far back as NetBSD 1.5).
1.56 lukem 519:
520: 20020320:

526: on send(2) operation. Be sure to have sbin/rtsol and usr.sbin/rtsold
1.55 itojun 527: newer than November 2001 when you upgrade the kernel.
528:
1.54 itojun 529: 20020311:
530: ssh configuration files were moved from /etc to /etc/ssh. Beware
531: if you restart your machine from remote. Note that sshd.conf needs
532: to be changed (due to the use of "/etc" inside).
533:
534: 20020223:
1.53 matt 535: Users of the VAX port will need to rebuild and install gas
536: so it deal with the now present register prefix used in all
537: the VAX assembly files.

1.50 itojun 539: 20020118:
540: ntpd user/group has been added. Need to hand add this in or builds
541: will break as mtree aborts early.
542:
543: Add the following into /etc/group:
544:

552: If you're attempting to build a snapshot on sparc64 and are getting
553: reloc errors from the toolchain groff binary this means your native
554: toolchain has some broken C++ bits.
555:
556: To fix:
557:
558: Build a new toolchain (i.e. build.sh -t)
559: Use the new toolchain to build and install natively (i.e. /usr/lib)
560:
561: gnu/lib/libgcc
1.51 pooka 562: gnu/lib/libstdc++
1.49 jmc 563:

565:
1.47 jmc 566: 20011201:

568: you've built and installed a system with the new toolchain up to this
1.52 wiz 569: point you do not have a working awk as its ability to do floating
1.47 jmc 570: point is broken.
571:
572: To build:
573:
574: remake and install gnu/lib/libgcc
575: remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links
1.48 jmc 576: against the new libgcc.a)
1.47 jmc 577:
1.46 thorpej 578: 20011128:
579: Kernel config information was changed to use defflag in
580: the various "files" files. Bug fixes to config(8) are
581: required in order for this to work properly. Make sure
582: to build and install in usr.sbin/config before attempting
583: to build a new kernel.

1.44 tv 589: 20011029:
590: The new document BUILDING.mdoc (view with nroff | more, or
591: see pre-generated .txt and .html versions) describes the build
592: procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
593: build process, are intended in the long run to replace this
594: manual update log.
595:
596: Users building a USE_NEW_TOOLCHAIN system should read the
597: BUILDING document for caveats. Generally, BUILDING supersedes
598: UPDATING for these systems, as tool updating is taken care of
599: by the new build system.
1.42 perry 600:

602: src/etc/Makefile now needs install to be able to handle
603: symlinks that point to nowhere. A bug in install that
604: prevented this was corrected.
605:
606: Solution: update and reinstall usr.bin/xinstall
607: Better Solution: Use the new toolchain and it will just work
608: for you.
1.40 lukem 609:
610: 20011006:

612: absolute path support added to mtree(8). Older mtree(8)s don't
613: understand the format.

615: Solution: update and reinstall usr.sbin/mtree
1.39 jmc 616:

623: a header file, uvm/uvm_vnode.h. There may be stale .depend
624: files that still reference this file.
625:
626: Solution: "make cleandir && make dependall" in affected
627: directories.
1.31 enami 628:
629: 20010803:
630: grep.info is now built from grep.texi using makeinfo. Since it
631: requires makeinfo v4.0, you need to install new texinfo before
632: building gnu/usr.bin/grep. To install new texinfo, please follow
633: the instruction described in 20010726 entry.
1.30 enami 634:
1.64 sommerfe 635: 20010803:
1.41 wiz 636: (i386 only): i386 kernel now uses new instructions like
1.111 simonb 637: `fxsave' which old gas doesn't understand. To build the
1.64 sommerfe 638: kernel successfully, you need to build and install a new toolchain,
639: (i.e., build.sh -t) or (temporarily) comment out "options I686_CPU"
640: from your kernel configuration until you rebuild your userland.
641: See 20011029 above and BUILDING file in this directory for more information.
642: [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]
1.29 bjh21 643:

657: Enabled correct .init/.fini processing in crt0. The way this
658: was done was to change a -I directive to cc(1), which means
659: make(1) will have a stale dependency (it will be checking the
660: timestamp on the wrong "dot_init.h").
661:
662: The symptom you will see is that new programs die with SIGSEGV
663: if you have a stale dependency.
664:
665: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
666: before starting your build.
1.26 thorpej 667:
668: 20010628:
669: A construct was added to uvm_page.h that uncovered a bug
670: in lint(1). If you get a warning/error about a non-portable
671: bitfield, update your lint(1) before proceeding.
1.21 jmc 672:

702: needs to be installed before make build.
1.10 christos 703:
704: 20010114:
705: introduce .if commands(target) in make(1). You need to
706: bring everything up-to-date first, then without installing
1.23 tron 707: anything make and install in usr.bin/make, then proceed
1.10 christos 708: with make build.
1.9 sommerfe 709:
710: 20010101:

712: afterinstall targets to run too soon; update again.
1.8 sommerfe 713:
714: 20001230:
715: New share/mk files needed to support .WAIT in SUBDIR variables.
716: If you get make errors,
717: (cd share/mk; make install)
718: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 719:
720: 20001019:
1.7 ad 721: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 722: major and minor numbers haven't changed, you should update your /dev
723: directory.
1.1 abs 724:
1.4 itojun 725: 20000929:
726: The following make directives are obsoleted.
727: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
728: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 729: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 730: additional library libcrypto_{idea,rc5}.
1.1 abs 731:
732:
733: Hints for a more successful build:
734: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 735: Use build.sh, but do not use its "expert mode":
1.132 jmmv 736: This will automatically build the tools in the
1.123 jmc 737: correct order, and it will keep the tools and the
738: new build products from interfering with the running
739: system. This will allow you to ignore most of the
740: other advice in this file.
1.2 mrg 741: Build a new kernel first:
742: This makes sure that any new system calls or features
743: expected by the new userland will be present. This
744: helps to avoid critical errors when upgrading.
1.1 abs 745: Use object directories:
746: This helps to keep stale object
747: files from polluting the build if a Makefile "forgets"
748: about one. It also makes it easier to clean up after
749: a build. It's also necessary if you want to use the
750: same source tree for multiple machines.
1.123 jmc 751: To use object directories with build.sh:
752: a) invoke build.sh with the "-M" or "-O" options.
753: To use object directories without using build.sh:
1.1 abs 754: a) cd /usr/src ; make cleandir
1.2 mrg 755: b) Add "OBJMACHINE=yes" to /etc/mk.conf
756: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 757: d) cd /usr/src ; make build
1.2 mrg 758: Note that running "make obj" in a directory will create
759: in obj.$MACHINE directory.
1.1 abs 760: Build to a DESTDIR:
1.123 jmc 761: This helps to keep old installed files (especially libraries)
762: from interfering with the new build.
763: To build to a DESTDIR with build.sh, use the "-D" option.
764: To build to a DESTDIR without using build.sh, set the DESTDIR
765: environment variable before running make build. It should be
766: set to the pathname of an initially empty directory.
767: Problems: if you do not use build.sh, you might need to
768: update critical utilities without using DESTDIR since
769: nothing is executed from what is installed in DESTDIR.
770: (See critical utils, below.)
1.1 abs 771: Build often:
772: This keeps critical utilities current enough to not choke
773: on any other part of the source tree that depends on up to
1.123 jmc 774: date functionality. If you use build.sh, you should not have
775: this problem.
1.1 abs 776:
777: What to do if things don't work:
778: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
779: When things don't work there is usually a few things that commonly
780: should be done.
781: 1) make includes
782: This should be done automatically by make build.
783: 2) cd share/mk && make install
784: Again, automatically done by make build.
785:
786: Failsafe rebuild of a small part of the tree:
787: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
788: To make sure you rebuild something correctly you want to do
789: something like the following:
790: 1) Make sure the includes and .mk files are up to date.
791: 2) Make sure any program used to build the particular
792: utility is up to date. (yacc, lex, etc...)
793: 3) cd ...path/to/util...
794: make cleandir
795: rm ...all obj directories...
796: make cleandir # yes, again
797: make obj
798: make depend && make
799:
800: Failsafe rebuild of the entire tree:
801: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
802: If you really want to make sure the source tree is clean and
1.2 mrg 803: ready for a build try the following. Note that sourcing /etc/mk.conf
804: (a make(1) Makefile) in this manner is not right, and will not work
805: for anyone who uses any make(1) features in /etc/mk.conf.
