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.

16: Recent changes:
17: ^^^^^^^^^^^^^^^
1.138 ! lukem 18:
! 19: 20050417:
! 20: postinstall(8) was moved from /etc to /usr/sbin and made part
! 21: of the "base" set, to make it easier to invoke after an
! 22: upgrade.
! 23:
1.136 cube 24: 20050325:
25: pcppi(4) was separated in two devices, adding attimer(4). Be sure
26: to add a config line for an attimer(4) device in your kernel
27: configuration, or you won't be able to set the pitch of the beep
1.137 cube 28: with wsconsctl. Depending on the default value for the pitch, you
29: might even not hear any more beep. Also, it is advised to attach both
30: devices the same way (i.e., both on isa or both on acpi) or the
31: pcppi(4) device may fail to find the attimer(4) one.
1.136 cube 32:
1.135 jmc 33: 20050211:
34: Fixes to tools/Makefile.gnuhost may cause UPDATE=1 builds in
35: some of the cross tools to fail if they use configure. Some configure's
36: cache the environment passed in and notice the new environment is
37: different and abort. Doing a clean in tools/ should be enough to
38: make a build continue.
39:
1.134 christos 40: 20050109:
41: Since su is using pam by default now, make sure that you have
42: /etc/pam.d populated (postinstall will do that automatically
43: for you). Otherwise su will fail open (i.e. will not require
44: a password).
45:
1.133 christos 46: 20041229:
47: Make had a path resolution bug that manifested itself as not
48: being able to install openpam.3. This bug has been fixed, but
49: you might need to rebuild make manually first to get through
50: the build.
51:
1.130 christos 52: 20041201:
53: Userland programs have been changed to use /dev/bpf instead of
54: /dev/bpfX. You need to create that device by installing a new
1.131 wiz 55: MAKEDEV and running it, or mv /dev/bpf0 /dev/bpf && rm /dev/bpf[0-9]*
1.99 mrg 56:
1.129 jmc 57: 20041006:
58:
59: A bug was introduced into /bin/sh (var.c rev 1.35) which causes
60: variables to not export correctly to subshells in all cases. This
61: will cause builds to break if that version of /bin/sh is installed
62: on the system. The proper version of /bin/sh can be verified with:
63:
64: ident /bin/sh | grep var
65:
66: Any /bin/sh w. version 1.35 will not work and needs to be updated
67: before attempting a build.
68:
1.127 christos 69: 20041001:
70: The ipfilter kernel sources moved from sys/netinet to
71: dist/sys/ipf/netinet. Due to the move some Makefile
72: dependencies are now dangling requiring a make cleandir
1.128 he 73: before they work again (kdump, ktruss, rescue, ipf, and
74: ftp-proxy are the victims).
1.127 christos 75:
1.125 atatat 76: 20040715:
77: The rc.d/sendmail script now uses a heuristic to determine
78: if sendmail should be started at boot time. It checks the
79: contents of /etc/mailer.conf, /etc/mail/submit.cf, and the
80: owner and mode of the sendmail binary to see if any changes
81: to the mail infrastructure have been made. If no changes
82: are detected, it will start an SMTP listener.
83:
84: Setting sendmail=NO in /etc/rc.conf will override this.
85:
86: If you are only using sendmail by default and only for
87: local delivery, it is important that you also update your
88: sendmail.cf so that the SMTP listener only listens on the
89: loopback interface.
90:
91: 20040715:
92: The method by which athhal-elf.o gets pulled into i386
93: kernel builds has been changed again. The latest version
94: of bsd.files.mk is no longer required.
95:
1.124 jmc 96: 20040621:
97: Due to the recent rototill of tools/compat it's crucial one starts
98: from a clean objdir under tools/*.
99:
100: This is mostly due to generated files (yacc and lex sources) needing
1.125 atatat 101: to be generated with new rules from bsd.hostprog.mk.
1.124 jmc 102:
103: The safest course is to rm -rf all objects under tools before building.
104:
1.121 lukem 105: 20040516:
106: The end-user modifiable X11 configuration has been moved
107: from /usr/X11R6/lib/X11/<dir> to /etc/X11/<dir>.
108: Ensure that src and xsrc is up to date, and run
109: "make cleandir" in src/x11 before your next build.
110:
1.126 lukem 111: postinstall currently doesn't migrate the files from
112: /usr/X11R6/lib/X11/* to /etc/X11/* although it does
113: detect that this needs to occur, so you'll have to
114: manually move these files yourself.
115:
1.119 atatat 116: 20040426:
117: Support for the original dynamic sysctl node structure has
118: been removed in favor of the newer layout. This affects
119: consumers of the create and delete interface, as well as
120: the dynamic discovery mechanism. This is believed only to
121: be the sysctl(8) binary itself, at this point in time, so
122: the only effect of this should be that a sysctl binary
123: built from sources dated between 2003/12/04 and 2004/03/24
124: will not work on a kernel built from sources dated after
125: 2004/04/25. If you need a new sysctl binary but build.sh
126: does not work, make sure that your revision of
1.120 atatat 127: src/sys/sys/sysctl.h is 1.112 (or later), and then the
128: do the following:
1.119 atatat 129:
1.120 atatat 130: cd /usr/src (or wherever your source tree is)
131: make USETOOLS=no includes
132: cd lib/libc
133: make USETOOLS=no dependall install
134: cd ../../sbin/sysctl
1.119 atatat 135: make USETOOLS=no dependall install
136:
1.122 itojun 137: If you are using older sysctl binary, GNU autoconf would fail to
138: identify your machine architecture, and tries to build binary for
139: "unknown-unknown-netbsd20F" or something like that. if that happens,
140: make sure to follow the above steps.
141:
1.118 dbj 142: 20040425:
143: The ffs superblock issues listed below under 20040109 and 20030402
144: are now automatically addressed by the /etc/rc.d/fixsb script or by
145: sysinst when it checks a a filesystem. The manual fsck_ffs -b16 -c4
146: invocation mentioned below will continue to work and is now
147: automated by those scripts. Note that under certain circumstances,
148: affected filesystems upgraded to a -current kernel first before
149: upgrading their userland with the fixsb and fsck_ffs fixes may
150: encounter a 'freeing free inode' panic when writing to the affected
151: filesystem, so it is a good idea to repair the filesystem as soon as
152: possible. For more details on the fixsb script, see pr install/25138.
153:
1.115 christos 154: 20040418:
1.121 lukem 155: statfs(2) and friends have been replaced with statvfs(2). Before
1.115 christos 156: installing a newly build userland make sure that you are running
157: a newly built kernel with COMPAT_20 set. In addition your libc
158: build might not work (undefined SYS_statfs symbol) because make
159: clean does not know how to remove files it does not know about
1.116 christos 160: anymore. Manually remove all generated .S sources and objects
161: from the libc build directory.
1.115 christos 162:
1.114 jmc 163: 20040326:
164: The method by which athhal-elf.o gets pulled into i386 kernel builds
1.117 jmc 165: has been changed. The file is now stored as a uuencoded file in CVS
1.114 jmc 166: and the generated Makefile will use the new .uue rules from bsd.file.mk
167: to build it.
168:
169: This means you must have the latest bsd.files.mk installed when
170: building a kernel without USETOOLS=yes.
171:
1.113 dan 172: 20040318:
173: A bug in the cgd(4) blowfish code was corrected, without
174: provision of backwards compatibility, after several public
175: notices over several months. Users of cgd with blowfish cipher
176: ONLY must dump their data before updating their kernels, and
177: recreate cgd's and restore data using the new kernel. See
178: (recent message to current-users, URL when mail-index has updated)
179:
1.108 bjh21 180: 20040313:
181: On acorn32, the opms and qms drivers have been withdrawn, and
182: the old wsqms driver is now called qms. Kernel config files
183: will need updating. See the ones in sys/arch/acorn32/conf
184: for examples.
185:
1.106 bjh21 186: 20040125:
187: On acorn32, the beep and sysbeep devices are no longer
188: needed, and will need to be deleted from kernel configuration
189: files.
1.105 bjh21 190:
1.102 dbj 191: 20040109:
192: Compatibility for old ffs superblock layouts has been
193: added, and the restrictive fsck checks have been reenabled
194: when using those layouts. If you have been using -current
195: since 20030402, you may find that fsck again signals fatal
1.110 dbj 196: superblock mismatches. To repair, make sure you have
1.111 simonb 197: an updated fsck_ffs and then you can use fsck_ffs -b 16 -c 4
1.109 dbj 198: to complete the filesystem upgrade. A message has
1.111 simonb 199: been added to the kernel which should detect this problem.
200: See the following discussion for more information:
1.112 keihan 201: http://mail-index.NetBSD.org/current-users/2004/01/11/0022.html
1.102 dbj 202:
1.99 mrg 203: 20031203:
1.100 keihan 204: New binutils builds may fail due to old dependencies.
1.99 mrg 205: It's necessary to "make cleandir" to ensure that
206: the dependencies will be rebuilt correctly.
1.98 wiz 207:
208: 20031111:
209: A newer mkdep is needed. Error noting that is
210: cc: Ambiguous abbreviation --
1.97 lukem 211:
212: 20031008:
213: /usr/include/sys/disklabel_mbr.h was removed.
214: It's necessary to "make cleandir" to ensure that
215: the dependencies will be rebuilt correctly.
1.96 christos 216:
1.109 dbj 217: 20031007:
1.111 simonb 218: A sign exension bug was fixed which set all the high bits
219: of our newly expanded ffs fs_flags. This should only
220: affect users who installed or upgraded in September of 2003.
1.109 dbj 221: A small utility program was posted to tech-kern which
1.111 simonb 222: should fix this problem, and a warning message was added
223: to the kernel which should discover and warn about it. See
224: http://mail-index.NetBSD.org/tech-kern/2003/10/07/0005.html
1.109 dbj 225:
1.96 christos 226: 20030906:
227: With the addition of siginfo support the old signal trampoline
228: code has been deprecated to COMPAT_16. Make sure that your running
229: kernel has COMPAT_16 enabled before building userland.
1.94 christos 230:
231: 20030801:
1.95 wiz 232: With the new openssl, there is some header and library shuffling.
1.94 christos 233: rm -f /usr/include/des.h /usr/include/kerberosIV/* /lib/libdes* \
1.95 wiz 234: /usr/lib/libdes* before building.
1.92 wiz 235:
236: 20030703:
237: Texinfo was updated to 4.6. To avoid failures when trying to
238: build the included texinfo files, do:
239:
240: cd src/gnu/usr.bin/texinfo
241: make MKINFO=no dependall install
1.90 wiz 242:
243: 20030630:
1.101 junyoung 244: Groff was updated to 1.19; it's probably necessary to do
1.91 wiz 245: cd share/mk && make install
1.90 wiz 246: cd src/gnu/usr.bin/groff
247: make MKMAN=no dependall install
248: (untested).
1.89 christos 249:
250: 20030516:
251: Due to bugs in the export handling code, invalid export lines
252: were accepted before and caused the kernel to panic when
253: mountd got restarted because it freed memory that had already
254: been freed. This has been fixed and the kernel checks
255: export addresses very strictly. If you upgrade your kernel,
256: make sure you also upgrade mountd, because if your export
257: file contains lines with an old inet4 address syntax (i.e.
258: a.b.c or a.b or a), they will get rejected by the new kernel.
1.87 bjh21 259:
260: 20030402:
261: The superblock layout for FFS was changed. If you have 1.6
262: fsck binaries, they will signal a fatal superblock mismatch
263: with the first alternate, because they compare too many
264: fields (even ones that aren't useful). If possible, upgrade
265: your fsck_ffs binary before using a new kernel.
266: None of this signals actual filesystem damage.
1.85 atatat 267:
268: 20030324:
269: sendmail version 8.12.8 was imported. Since sendmail is
270: now setgid to the smmsp group, and runs in "collection"
271: mode for most common activities, there is a new config
272: file called submit.cf that needs to live in /etc/mail.
273: The generic submit.cf sample in /usr/share/sendmail/cf
274: is named netbsd-msp.cf. Upgrading your regular sendmail
275: configuration file is also strongly advised.
276:
277: See the section named "MESSAGE SUBMISSION PROGRAM" in
278: the updated /usr/share/sendmail/README file for more
279: information.
1.82 wiz 280:
281: 20030117:
282: Texinfo was updated to 4.3. To avoid failures when trying to
283: build the included texinfo files, do:
284:
285: cd src/gnu/usr.bin/texinfo
286: make MKINFO=no dependall install
1.81 lukem 287:
288: 20021223:
289: The METALOG format changed slightly, to remove the leading
290: "${DESTDIR}" from path names.
291: This only affects people building with UNPRIVED.
292: For complete safety, remove the DESTDIR entirely and
293: update tools/mtree, before running make build.
1.88 itojun 294:
295: 20021219:
296: CVS repository layout was changed. See the following for details
297: if you are using (anonymous) cvs to update your tree.
298:
1.93 salo 299: http://mail-index.NetBSD.org/netbsd-announce/2002/12/19/0000.html
1.80 lukem 300:
301: 20021219:
302: install(1) had a '-N dbdir' option added, to specify an
303: alternate location to look up users & groups (instead
304: of the host system passwd(5) and group(5) databases).
305:
306: The build system was modified to take advantage of
307: this option (using ${NETBSDSRCDIR}/etc), so if you
1.83 kei 308: use USETOOLS==no, you may have to rebuild and
1.80 lukem 309: reinstall usr.bin/xinstall first.
1.78 lukem 310:
311: 20021130:
312: fparseln(3) moved from libutil to libc.
313: If building to DESTDIR=/, reinstall the includes
314: and rebuild libc:
315: make includes
316: make do-lib-libc
317: If using build.sh, "cd tools/compat && make clean"
318: before rebuilding the tools.
1.77 lukem 319:
320: 20021126:
321: The mk.conf(5) variable SYS_INCLUDE has been deprecated,
322: including the optional "SYS_INCLUDE=symlinks" support.
323: All header files, including <sys/*.h> are copied into
324: /usr/include.
1.76 thorpej 325:
326: 20021121:
327: The C run-time support files crtbegin.o and crtend.o
328: (and their companions crtbeginS.o and crtendS.o) were
329: split up, with new crti.o and crtn.o files resulting.
330: This means that libtool needs to be rebuilt once the
331: new libraries are installed. The process of rebuilding
332: libtool will cause it to automatically notice the new
333: required files, but it *must* be rebuilt in order to
334: do this.
335:
336: An out-of-date libtool will result in shared libraries
337: which lack _init() and _fini() routines, which means that
338: their global contructors/destructors will not be invoked.
1.75 thorpej 339:
340: 20021121:
341: A bug related to how ARM ELF objects were tagged has been
342: corrected.
343:
344: NetBSD ARM ELF uses the soft-VFP floating point model by
345: default. However, the assembler lacked support for marking
346: objects as using the VFP floating point format, and the
1.79 wiz 347: compiler was not properly passing the flag indicating "soft-VFP"
1.75 thorpej 348: to the assembler.
349:
350: Unfortunately, this means that the linker will now consider
351: old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be
352: incompatible with new (properly marked) objects.
353:
354: The problem will only manifest itself if you attempt to compile
355: a new program using the fixed toolchain, and link that program
356: against old libraries which do not have the proper "softvfp"
357: markings. ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES
358: WILL CONTINUE TO WORK PROPERLY.
359:
360: The only work-around for the problem is to recompile all of
361: the libraries on the system. The easiest way to do this for
1.79 wiz 362: system libraries is to install a binary snapshot; they are
1.93 salo 363: generally available on releng.NetBSD.org. Any packages you
1.75 thorpej 364: have installed which supply libraries will have to be recompiled
365: if you wish to link new programs against those libraries.
366:
367: If you have questions about this matter, please contact
1.93 salo 368: port-arm@NetBSD.org.
1.73 provos 369:
370: 20021011:
371: Systrace has been improved to support privilege elevation.
372: Updating the kernel requires the userland part of systrace
1.79 wiz 373: to be rebuilt.
1.72 thorpej 374:
375: 20021010:
376: The config(8) grammar was changed to allow options to register
377: dependencies on attributes, as well as other options. Users
378: must update and reinstall usr.sbin/config before building a new
379: kernel.
1.70 thorpej 380:
381: 20021009:
382: A new attribute dependency syntax was introduced to config(8),
383: which is now used by the SCSI configuration description. Users
1.71 wiz 384: must update and reinstall usr.sbin/config before building a new
1.70 thorpej 385: kernel.
1.69 thorpej 386:
387: 20021003:
388: Several changes have been made to the autoconfiguration
389: framework. Users must update and reinstall usr.sbin/config
390: before building a new kernel.
1.74 jschauma 391:
392: 20021001:
393: The i386mp branch has been merged. To compile a kernel, users
394: will need to add the option 'cpu* at mainbus?' to their configuration
395: file. Multiprocessor kernels will need
396: ioapic* at mainbus? apid ?
397: options MULTIPROCESSOR
398: options COM_MPLOCK

401: MKDYNAMICROOT=yes enabled by default, which means that
402: certain shared libraries are installed into /lib, the shared
403: linker is installed into /libexec, and all programs in /bin
404: and /sbin are dynamically linked.
405: If you do not use "make build", you should ensure that
406: you have the libraries and shared linker in the new locations,
407: with:
408: make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so
1.67 lukem 409:
410: 20020917:
411: USE_NEW_TOOLCHAIN has been replaced with:
412: - TOOLCHAIN_MISSING -- set to "yes" on platforms for which
413: there is no working in-tree toolchain (hppa, ns32k, sh5,
414: x86_64).
415: - EXTERNAL_TOOLCHAIN -- if defined by the user, points to the
1.79 wiz 416: root of an external toolchain (e.g. /usr/local/gnu). This
1.67 lukem 417: enables the cross-build framework even for TOOLCHAIN_MISSING
418: platforms.
1.66 gehenna 419:
420: 20020906:
421: gehenna-devsw has been merged into the trunk. Need to update and
1.79 wiz 422: reinstall usr.sbin/config before building the kernel.
1.65 lukem 423:
424: 20020822:
425: Crunched rescue tools (contents of /bin and /sbin, plus others)
426: are now provided in /rescue.
427:
428: To ensure that these are built statically linked (no matter
429: what the setting of LDSTATIC is), use a crunchgen(1) built
430: from sources newer than 20020820 (see the next entry).
431:

1.59 lukem 466:
467: 20020426:
468: etc/postinstall added, which performs various checks for
469: configuration file updates and changes, and can fix most of
470: the problems identified.
471: This should make it much easier to upgrade a system's
472: configuration from earlier systems (as far back as NetBSD 1.5).

506: If you're attempting to build a snapshot on sparc64 and are getting
507: reloc errors from the toolchain groff binary this means your native
508: toolchain has some broken C++ bits.
509:
510: To fix:
511:
512: Build a new toolchain (i.e. build.sh -t)
513: Use the new toolchain to build and install natively (i.e. /usr/lib)
514:
515: gnu/lib/libgcc
1.51 pooka 516: gnu/lib/libstdc++
1.49 jmc 517:

1.47 jmc 520: 20011201:
521: In order for a sparc64 build to work you must have a working awk. If
522: you've built and installed a system with the new toolchain up to this
1.52 wiz 523: point you do not have a working awk as its ability to do floating
1.47 jmc 524: point is broken.
525:
526: To build:
527:
528: remake and install gnu/lib/libgcc
529: remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links
1.48 jmc 530: against the new libgcc.a)
1.47 jmc 531:
1.46 thorpej 532: 20011128:
533: Kernel config information was changed to use defflag in
534: the various "files" files. Bug fixes to config(8) are
535: required in order for this to work properly. Make sure
536: to build and install in usr.sbin/config before attempting
537: to build a new kernel.

1.44 tv 543: 20011029:
544: The new document BUILDING.mdoc (view with nroff | more, or
545: see pre-generated .txt and .html versions) describes the build
546: procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
547: build process, are intended in the long run to replace this
548: manual update log.
549:
550: Users building a USE_NEW_TOOLCHAIN system should read the
551: BUILDING document for caveats. Generally, BUILDING supersedes
552: UPDATING for these systems, as tool updating is taken care of
553: by the new build system.
1.42 perry 554:
555: 20011028:
556: src/etc/Makefile now needs install to be able to handle
557: symlinks that point to nowhere. A bug in install that
558: prevented this was corrected.
559:
560: Solution: update and reinstall usr.bin/xinstall
561: Better Solution: Use the new toolchain and it will just work
562: for you.
1.40 lukem 563:

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

569: Solution: update and reinstall usr.sbin/mtree
1.39 jmc 570:

577: a header file, uvm/uvm_vnode.h. There may be stale .depend
578: files that still reference this file.
579:
580: Solution: "make cleandir && make dependall" in affected
581: directories.
1.31 enami 582:
583: 20010803:
584: grep.info is now built from grep.texi using makeinfo. Since it
585: requires makeinfo v4.0, you need to install new texinfo before
586: building gnu/usr.bin/grep. To install new texinfo, please follow
587: the instruction described in 20010726 entry.
1.30 enami 588:
1.64 sommerfe 589: 20010803:
1.41 wiz 590: (i386 only): i386 kernel now uses new instructions like
1.111 simonb 591: `fxsave' which old gas doesn't understand. To build the
1.64 sommerfe 592: kernel successfully, you need to build and install a new toolchain,
593: (i.e., build.sh -t) or (temporarily) comment out "options I686_CPU"
594: from your kernel configuration until you rebuild your userland.
595: See 20011029 above and BUILDING file in this directory for more information.
596: [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]
1.29 bjh21 597:

607: cd src/gnu/usr.bin/texinfo
608: make MKINFO=no dependall install
1.25 thorpej 609:
610: 20010718:
611: Enabled correct .init/.fini processing in crt0. The way this
612: was done was to change a -I directive to cc(1), which means
613: make(1) will have a stale dependency (it will be checking the
614: timestamp on the wrong "dot_init.h").
615:
616: The symptom you will see is that new programs die with SIGSEGV
617: if you have a stale dependency.
618:
619: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
620: before starting your build.
1.26 thorpej 621:
622: 20010628:
623: A construct was added to uvm_page.h that uncovered a bug
624: in lint(1). If you get a warning/error about a non-portable
625: bitfield, update your lint(1) before proceeding.
1.21 jmc 626:
627: 20010226:
1.22 jmc 628: Added named user/group to system. Need to hand add this in or builds
1.21 jmc 629: will break as mtree aborts early.

1.22 jmc 635: to /etc/group and add:
636:

641: Now a make build should progress.
1.18 jmc 642:
643: 20010219:
1.52 wiz 644: get/setprogname() added. Any hostprogs that may use this will need
1.111 simonb 645: to be bootstrapped manually until the host system is current.
1.18 jmc 646:
1.111 simonb 647: Known problems: sys/arch/macppc/stand/fixcoff
1.19 cgd 648: usr.sbin/config (adding -DMAKE_BOOTSTRAP to
649: CFLAGS and rebuilding should work)
1.20 jmc 650: usr.sbin/mdsetimage - Build a static copy if
1.111 simonb 651: building a snapshot before fully bootstrapped.
1.15 christos 652:
653: 20010204:
654: prepare the code to compile with stricter gcc flags. in
655: particular start eliminating redundant declarations. Yacc
656: needs to be installed before make build.
1.10 christos 657:
658: 20010114:
659: introduce .if commands(target) in make(1). You need to
660: bring everything up-to-date first, then without installing
1.23 tron 661: anything make and install in usr.bin/make, then proceed
1.10 christos 662: with make build.
1.9 sommerfe 663:
664: 20010101:
665: bsd.subdir.mk committed 20001230 had a bug which caused
666: afterinstall targets to run too soon; update again.
1.8 sommerfe 667:
668: 20001230:
669: New share/mk files needed to support .WAIT in SUBDIR variables.
670: If you get make errors,
671: (cd share/mk; make install)
672: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 673:
674: 20001019:
1.7 ad 675: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 676: major and minor numbers haven't changed, you should update your /dev
677: directory.
1.1 abs 678:
1.4 itojun 679: 20000929:
680: The following make directives are obsoleted.
681: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
682: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 683: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 684: additional library libcrypto_{idea,rc5}.
1.1 abs 685:
686:
687: Hints for a more successful build:
688: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 689: Use build.sh, but do not use its "expert mode":
1.132 jmmv 690: This will automatically build the tools in the
1.123 jmc 691: correct order, and it will keep the tools and the
692: new build products from interfering with the running
693: system. This will allow you to ignore most of the
694: other advice in this file.
1.2 mrg 695: Build a new kernel first:
696: This makes sure that any new system calls or features
697: expected by the new userland will be present. This
698: helps to avoid critical errors when upgrading.
1.1 abs 699: Use object directories:
700: This helps to keep stale object
701: files from polluting the build if a Makefile "forgets"
702: about one. It also makes it easier to clean up after
703: a build. It's also necessary if you want to use the
704: same source tree for multiple machines.
1.123 jmc 705: To use object directories with build.sh:
706: a) invoke build.sh with the "-M" or "-O" options.
707: To use object directories without using build.sh:
1.1 abs 708: a) cd /usr/src ; make cleandir
1.2 mrg 709: b) Add "OBJMACHINE=yes" to /etc/mk.conf
710: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 711: d) cd /usr/src ; make build
1.2 mrg 712: Note that running "make obj" in a directory will create
713: in obj.$MACHINE directory.
1.1 abs 714: Build to a DESTDIR:
1.123 jmc 715: This helps to keep old installed files (especially libraries)
716: from interfering with the new build.
717: To build to a DESTDIR with build.sh, use the "-D" option.
718: To build to a DESTDIR without using build.sh, set the DESTDIR
719: environment variable before running make build. It should be
720: set to the pathname of an initially empty directory.
721: Problems: if you do not use build.sh, you might need to
722: update critical utilities without using DESTDIR since
723: nothing is executed from what is installed in DESTDIR.
724: (See critical utils, below.)
1.1 abs 725: Build often:
726: This keeps critical utilities current enough to not choke
727: on any other part of the source tree that depends on up to
1.123 jmc 728: date functionality. If you use build.sh, you should not have
729: this problem.
1.1 abs 730:
731: What to do if things don't work:
732: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
733: When things don't work there is usually a few things that commonly
734: should be done.
735: 1) make includes
736: This should be done automatically by make build.
737: 2) cd share/mk && make install
738: Again, automatically done by make build.
739:
740: Failsafe rebuild of a small part of the tree:
741: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
742: To make sure you rebuild something correctly you want to do
743: something like the following:
744: 1) Make sure the includes and .mk files are up to date.
745: 2) Make sure any program used to build the particular
746: utility is up to date. (yacc, lex, etc...)
747: 3) cd ...path/to/util...
748: make cleandir
749: rm ...all obj directories...
750: make cleandir # yes, again
751: make obj
752: make depend && make
753:
754: Failsafe rebuild of the entire tree:
755: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
756: If you really want to make sure the source tree is clean and
1.2 mrg 757: ready for a build try the following. Note that sourcing /etc/mk.conf
758: (a make(1) Makefile) in this manner is not right, and will not work
759: for anyone who uses any make(1) features in /etc/mk.conf.
