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.

8: Recent changes:
9: ^^^^^^^^^^^^^^^
1.77 ! lukem 10:
! 11: 20021126:
! 12: The mk.conf(5) variable SYS_INCLUDE has been deprecated,
! 13: including the optional "SYS_INCLUDE=symlinks" support.
! 14: All header files, including <sys/*.h> are copied into
! 15: /usr/include.
1.76 thorpej 16:
17: 20021121:
18: The C run-time support files crtbegin.o and crtend.o
19: (and their companions crtbeginS.o and crtendS.o) were
20: split up, with new crti.o and crtn.o files resulting.
21: This means that libtool needs to be rebuilt once the
22: new libraries are installed. The process of rebuilding
23: libtool will cause it to automatically notice the new
24: required files, but it *must* be rebuilt in order to
25: do this.
26:
27: An out-of-date libtool will result in shared libraries
28: which lack _init() and _fini() routines, which means that
29: their global contructors/destructors will not be invoked.
1.75 thorpej 30:
31: 20021121:
32: A bug related to how ARM ELF objects were tagged has been
33: corrected.
34:
35: NetBSD ARM ELF uses the soft-VFP floating point model by
36: default. However, the assembler lacked support for marking
37: objects as using the VFP floating point format, and the
38: compiler was no properly passing the flag indicating "soft-VFP"
39: to the assembler.
40:
41: Unfortunately, this means that the linker will now consider
42: old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be
43: incompatible with new (properly marked) objects.
44:
45: The problem will only manifest itself if you attempt to compile
46: a new program using the fixed toolchain, and link that program
47: against old libraries which do not have the proper "softvfp"
48: markings. ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES
49: WILL CONTINUE TO WORK PROPERLY.
50:
51: The only work-around for the problem is to recompile all of
52: the libraries on the system. The easiest way to do this for
53: system libraries is to install a binary snapshot; there are
54: generally available on releng.netbsd.org. Any packages you
55: have installed which supply libraries will have to be recompiled
56: if you wish to link new programs against those libraries.
57:
58: If you have questions about this matter, please contact
59: port-arm@netbsd.org.
1.73 provos 60:
61: 20021011:
62: Systrace has been improved to support privilege elevation.
63: Updating the kernel requires the userland part of systrace
64: to be rebuild.
1.72 thorpej 65:
66: 20021010:
67: The config(8) grammar was changed to allow options to register
68: dependencies on attributes, as well as other options. Users
69: must update and reinstall usr.sbin/config before building a new
70: kernel.
1.70 thorpej 71:
72: 20021009:
73: A new attribute dependency syntax was introduced to config(8),
74: which is now used by the SCSI configuration description. Users
1.71 wiz 75: must update and reinstall usr.sbin/config before building a new
1.70 thorpej 76: kernel.
1.69 thorpej 77:
78: 20021003:
79: Several changes have been made to the autoconfiguration
80: framework. Users must update and reinstall usr.sbin/config
81: before building a new kernel.
1.74 jschauma 82:
83: 20021001:
84: The i386mp branch has been merged. To compile a kernel, users
85: will need to add the option 'cpu* at mainbus?' to their configuration
86: file. Multiprocessor kernels will need
87: ioapic* at mainbus? apid ?
88: options MULTIPROCESSOR
89: options COM_MPLOCK
1.68 lukem 90:
91: 20020922:
92: MKDYNAMICROOT=yes enabled by default, which means that
93: certain shared libraries are installed into /lib, the shared
94: linker is installed into /libexec, and all programs in /bin
95: and /sbin are dynamically linked.
96: If you do not use "make build", you should ensure that
97: you have the libraries and shared linker in the new locations,
98: with:
99: make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so
1.67 lukem 100:
101: 20020917:
102: USE_NEW_TOOLCHAIN has been replaced with:
103: - TOOLCHAIN_MISSING -- set to "yes" on platforms for which
104: there is no working in-tree toolchain (hppa, ns32k, sh5,
105: x86_64).
106: - EXTERNAL_TOOLCHAIN -- if defined by the user, points to the
107: root ofan external toolchain (e.g. /usr/local/gnu). This
108: enables the cross-build framework even for TOOLCHAIN_MISSING
109: platforms.
1.66 gehenna 110:
111: 20020906:
112: gehenna-devsw has been merged into the trunk. Need to update and
113: reinstall usr.sbin/config before build the kernel.
1.65 lukem 114:
115: 20020822:
116: Crunched rescue tools (contents of /bin and /sbin, plus others)
117: are now provided in /rescue.
118:
119: To ensure that these are built statically linked (no matter
120: what the setting of LDSTATIC is), use a crunchgen(1) built
121: from sources newer than 20020820 (see the next entry).
122:
123: 20020820:
124: crunchgen(1) changed to ensure that the generated program
125: is statically linked.
126:
127: Solution: update and reinstall usr.bin/crunch
1.61 itojun 128:
129: 20020515:
130: sshd user/group has been added. Need to hand add this in, or sshd
131: will not let you log in (with default, or UsePrivlegeSeparation=yes)
132:
133: Add the following into /etc/group:
134:
135: sshd:*:16:
136:
137: and the following to /etc/master.passwd (via vipw):
138:
1.63 enami 139: sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin
1.61 itojun 140:
1.62 jdolecek 141: also /var/chroot/sshd directory needs to be present (digged as a part of
1.61 itojun 142: build process).
1.60 sommerfe 143:
144: 20020426:
145: NBUILDJOBS obsoleted in favor of just using -j.
1.59 lukem 146:
147: 20020426:
148: etc/postinstall added, which performs various checks for
149: configuration file updates and changes, and can fix most of
150: the problems identified.
151: This should make it much easier to upgrade a system's
152: configuration from earlier systems (as far back as NetBSD 1.5).
1.56 lukem 153:
154: 20020320:
155: <bsd.lib.mk> needs a new install(1) for it's "-a cmd" support.
1.57 itojun 156: build and install at usr.bin/xinstall before the build.
1.56 lukem 157:
1.55 itojun 158: 20020319:
159: raw IPv6 socket now makes strict checking for sa_family and sa_len
160: on send(2) operation. be sure to have sbin/rtsol and usr.sbin/rtsold
161: newer than November 2001 when you upgrade the kernel.
162:
1.54 itojun 163: 20020311:
164: ssh configuration files were moved from /etc to /etc/ssh. Beware
165: if you restart your machine from remote. Note that sshd.conf needs
166: to be changed (due to the use of "/etc" inside).
167:
168: 20020223:
1.53 matt 169: Users of the VAX port will need to rebuild and install gas
170: so it deal with the now present register prefix used in all
171: the VAX assembly files.
172:
1.50 itojun 173: 20020118:
174:
175: ntpd user/group has been added. Need to hand add this in or builds
176: will break as mtree aborts early.
177:
178: Add the following into /etc/group:
179:
180: ntpd:*:15:
181:
182: and the following to /etc/master.passwd (via vipw):
183:
184: ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin
185:
1.49 jmc 186: 20011207:
187:
188: If you're attempting to build a snapshot on sparc64 and are getting
189: reloc errors from the toolchain groff binary this means your native
190: toolchain has some broken C++ bits.
191:
192: To fix:
193:
194: Build a new toolchain (i.e. build.sh -t)
195: Use the new toolchain to build and install natively (i.e. /usr/lib)
196:
197: gnu/lib/libgcc
1.51 pooka 198: gnu/lib/libstdc++
1.49 jmc 199:
200: After this a snapshot will be able to be built.
201:
1.47 jmc 202: 20011201:
203: In order for a sparc64 build to work you must have a working awk. If
204: you've built and installed a system with the new toolchain up to this
1.52 wiz 205: point you do not have a working awk as its ability to do floating
1.47 jmc 206: point is broken.
207:
208: To build:
209:
210: remake and install gnu/lib/libgcc
211: remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links
1.48 jmc 212: against the new libgcc.a)
1.47 jmc 213:
1.46 thorpej 214: 20011128:
215: Kernel config information was changed to use defflag in
216: the various "files" files. Bug fixes to config(8) are
217: required in order for this to work properly. Make sure
218: to build and install in usr.sbin/config before attempting
219: to build a new kernel.
220:
1.45 yamt 221: 20011030:
222: libc/locale/wcstod.c now needs new lint(1). Update lint(1)
223: before building libc.
1.43 mason 224:
1.44 tv 225: 20011029:
226: The new document BUILDING.mdoc (view with nroff | more, or
227: see pre-generated .txt and .html versions) describes the build
228: procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
229: build process, are intended in the long run to replace this
230: manual update log.
231:
232: Users building a USE_NEW_TOOLCHAIN system should read the
233: BUILDING document for caveats. Generally, BUILDING supersedes
234: UPDATING for these systems, as tool updating is taken care of
235: by the new build system.
1.42 perry 236:
237: 20011028:
238: src/etc/Makefile now needs install to be able to handle
239: symlinks that point to nowhere. A bug in install that
240: prevented this was corrected.
241:
242: Solution: update and reinstall usr.bin/xinstall
243: Better Solution: Use the new toolchain and it will just work
244: for you.
1.40 lukem 245:
246: 20011006:
247: /etc/mtree/NetBSD.dist has been updated to take advantage of
248: absolute path support added to mtree(8). Older mtree(8)s don't
249: understand the format.
250:
251: Solution: update and reinstall usr.sbin/mtree
1.39 jmc 252:
253: 20011004:
254: Crunchgen has been updated to work via reach-over makefiles. Updating
255: is suggested before running a snapshot build
1.36 tv 256:
1.35 thorpej 257: 20010915:
258: The new "ubcperf" code committed by Chuck Silvers removed
259: a header file, uvm/uvm_vnode.h. There may be stale .depend
260: files that still reference this file.
261:
262: Solution: "make cleandir && make dependall" in affected
263: directories.
1.31 enami 264:
265: 20010803:
266: grep.info is now built from grep.texi using makeinfo. Since it
267: requires makeinfo v4.0, you need to install new texinfo before
268: building gnu/usr.bin/grep. To install new texinfo, please follow
269: the instruction described in 20010726 entry.
1.30 enami 270:
1.64 sommerfe 271: 20010803:
1.41 wiz 272: (i386 only): i386 kernel now uses new instructions like
273: `fxsave' which old gas doesn't understand. To build the
1.64 sommerfe 274: kernel successfully, you need to build and install a new toolchain,
275: (i.e., build.sh -t) or (temporarily) comment out "options I686_CPU"
276: from your kernel configuration until you rebuild your userland.
277: See 20011029 above and BUILDING file in this directory for more information.
278: [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]
1.29 bjh21 279:
280: 20010731:
281: Bootloader update on ELF platforms. DDB in kernels from before
282: this will be unable to read symbol tables provided by newer
283: bootloaders.
1.27 assar 284:
285: 20010726:
286: Texinfo was updated to 4.0. To avoid failures when trying to
1.28 assar 287: build the included texinfo files, do:
288:
289: cd src/gnu/usr.bin/texinfo
290: make MKINFO=no dependall install
1.25 thorpej 291:
292: 20010718:
293: Enabled correct .init/.fini processing in crt0. The way this
294: was done was to change a -I directive to cc(1), which means
295: make(1) will have a stale dependency (it will be checking the
296: timestamp on the wrong "dot_init.h").
297:
298: The symptom you will see is that new programs die with SIGSEGV
299: if you have a stale dependency.
300:
301: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
302: before starting your build.
1.26 thorpej 303:
304: 20010628:
305: A construct was added to uvm_page.h that uncovered a bug
306: in lint(1). If you get a warning/error about a non-portable
307: bitfield, update your lint(1) before proceeding.
1.21 jmc 308:
309: 20010226:
1.22 jmc 310: Added named user/group to system. Need to hand add this in or builds
1.21 jmc 311: will break as mtree aborts early.
312:
313: To work around add by hand:
314:
315: named:*:14:
316:
1.22 jmc 317: to /etc/group and add:
318:
319: named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin
320:
321: to master.passwd (use vipw for instance if doing by hand).
322:
323: Now a make build should progress.
1.18 jmc 324:
325: 20010219:
1.52 wiz 326: get/setprogname() added. Any hostprogs that may use this will need
1.20 jmc 327: to be bootstrapped manually until the host system is current.
1.18 jmc 328:
329: Known problems: sys/arch/macppc/stand/fixcoff
1.19 cgd 330: usr.sbin/config (adding -DMAKE_BOOTSTRAP to
331: CFLAGS and rebuilding should work)
1.20 jmc 332: usr.sbin/mdsetimage - Build a static copy if
333: building a snapshot before fully bootstrapped.
1.15 christos 334:
335: 20010204:
336: prepare the code to compile with stricter gcc flags. in
337: particular start eliminating redundant declarations. Yacc
338: needs to be installed before make build.
1.10 christos 339:
340: 20010114:
341: introduce .if commands(target) in make(1). You need to
342: bring everything up-to-date first, then without installing
1.23 tron 343: anything make and install in usr.bin/make, then proceed
1.10 christos 344: with make build.
1.9 sommerfe 345:
346: 20010101:
347: bsd.subdir.mk committed 20001230 had a bug which caused
348: afterinstall targets to run too soon; update again.
1.8 sommerfe 349:
350: 20001230:
351: New share/mk files needed to support .WAIT in SUBDIR variables.
352: If you get make errors,
353: (cd share/mk; make install)
354: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 355:
356: 20001019:
1.7 ad 357: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 358: major and minor numbers haven't changed, you should update your /dev
359: directory.
1.1 abs 360:
1.4 itojun 361: 20000929:
362: The following make directives are obsoleted.
363: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
364: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 365: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 366: additional library libcrypto_{idea,rc5}.
1.1 abs 367:
368:
369: Hints for a more successful build:
370: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 371: Build a new kernel first:
372: This makes sure that any new system calls or features
373: expected by the new userland will be present. This
374: helps to avoid critical errors when upgrading.
1.1 abs 375: Use object directories:
376: This helps to keep stale object
377: files from polluting the build if a Makefile "forgets"
378: about one. It also makes it easier to clean up after
379: a build. It's also necessary if you want to use the
380: same source tree for multiple machines.
381: To use object directories:
382: a) cd /usr/src ; make cleandir
1.2 mrg 383: b) Add "OBJMACHINE=yes" to /etc/mk.conf
384: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 385: d) cd /usr/src ; make build
1.2 mrg 386: Note that running "make obj" in a directory will create
387: in obj.$MACHINE directory.
1.1 abs 388: Build to a DESTDIR:
389: This helps to keep old
390: installed files (especially libraries) from interfering
391: with the new build.
392: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 393: variable before running make build. It should be set to
394: the pathname of an initially empty directory.
1.1 abs 395: Problems: you might need to update critical utilities
396: without using DESTDIR since nothing is executed
397: from what is installed in DESTDIR.
398: (See critical utils, below)
399: Build often:
400: This keeps critical utilities current enough to not choke
401: on any other part of the source tree that depends on up to
402: date functionality.
403:
404: What to do if things don't work:
405: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
406: When things don't work there is usually a few things that commonly
407: should be done.
408: 1) make includes
409: This should be done automatically by make build.
410: 2) cd share/mk && make install
411: Again, automatically done by make build.
412:
413: Failsafe rebuild of a small part of the tree:
414: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
415: To make sure you rebuild something correctly you want to do
416: something like the following:
417: 1) Make sure the includes and .mk files are up to date.
418: 2) Make sure any program used to build the particular
419: utility is up to date. (yacc, lex, etc...)
420: 3) cd ...path/to/util...
421: make cleandir
422: rm ...all obj directories...
423: make cleandir # yes, again
424: make obj
425: make depend && make
426:
427: Failsafe rebuild of the entire tree:
428: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
429: If you really want to make sure the source tree is clean and
1.2 mrg 430: ready for a build try the following. Note that sourcing /etc/mk.conf
431: (a make(1) Makefile) in this manner is not right, and will not work
432: for anyone who uses any make(1) features in /etc/mk.conf.
1.1 abs 433:
