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: ^^^^^^^^^^^^^^^
1.55 ! itojun 10: 20020319:
! 11: raw IPv6 socket now makes strict checking for sa_family and sa_len
! 12: on send(2) operation. be sure to have sbin/rtsol and usr.sbin/rtsold
! 13: newer than November 2001 when you upgrade the kernel.
! 14:
1.54 itojun 15: 20020311:
16: ssh configuration files were moved from /etc to /etc/ssh. Beware
17: if you restart your machine from remote. Note that sshd.conf needs
18: to be changed (due to the use of "/etc" inside).
19:
20: 20020223:
1.53 matt 21: Users of the VAX port will need to rebuild and install gas
22: so it deal with the now present register prefix used in all
23: the VAX assembly files.
24:
1.50 itojun 25: 20020118:
26:
27: ntpd user/group has been added. Need to hand add this in or builds
28: will break as mtree aborts early.
29:
30: Add the following into /etc/group:
31:
32: ntpd:*:15:
33:
34: and the following to /etc/master.passwd (via vipw):
35:
36: ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin
37:
1.49 jmc 38: 20011207:
39:
40: If you're attempting to build a snapshot on sparc64 and are getting
41: reloc errors from the toolchain groff binary this means your native
42: toolchain has some broken C++ bits.
43:
44: To fix:
45:
46: Build a new toolchain (i.e. build.sh -t)
47: Use the new toolchain to build and install natively (i.e. /usr/lib)
48:
49: gnu/lib/libgcc
1.51 pooka 50: gnu/lib/libstdc++
1.49 jmc 51:
52: After this a snapshot will be able to be built.
53:
1.47 jmc 54: 20011201:
55: In order for a sparc64 build to work you must have a working awk. If
56: you've built and installed a system with the new toolchain up to this
1.52 wiz 57: point you do not have a working awk as its ability to do floating
1.47 jmc 58: point is broken.
59:
60: To build:
61:
62: remake and install gnu/lib/libgcc
63: remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links
1.48 jmc 64: against the new libgcc.a)
1.47 jmc 65:
1.46 thorpej 66: 20011128:
67: Kernel config information was changed to use defflag in
68: the various "files" files. Bug fixes to config(8) are
69: required in order for this to work properly. Make sure
70: to build and install in usr.sbin/config before attempting
71: to build a new kernel.
72:
1.45 yamt 73: 20011030:
74: libc/locale/wcstod.c now needs new lint(1). Update lint(1)
75: before building libc.
1.43 mason 76:
1.44 tv 77: 20011029:
78: The new document BUILDING.mdoc (view with nroff | more, or
79: see pre-generated .txt and .html versions) describes the build
80: procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
81: build process, are intended in the long run to replace this
82: manual update log.
83:
84: Users building a USE_NEW_TOOLCHAIN system should read the
85: BUILDING document for caveats. Generally, BUILDING supersedes
86: UPDATING for these systems, as tool updating is taken care of
87: by the new build system.
1.42 perry 88:
89: 20011028:
90: src/etc/Makefile now needs install to be able to handle
91: symlinks that point to nowhere. A bug in install that
92: prevented this was corrected.
93:
94: Solution: update and reinstall usr.bin/xinstall
95: Better Solution: Use the new toolchain and it will just work
96: for you.
1.40 lukem 97:
98: 20011006:
99: /etc/mtree/NetBSD.dist has been updated to take advantage of
100: absolute path support added to mtree(8). Older mtree(8)s don't
101: understand the format.
102:
103: Solution: update and reinstall usr.sbin/mtree
1.39 jmc 104:
105: 20011004:
106: Crunchgen has been updated to work via reach-over makefiles. Updating
107: is suggested before running a snapshot build
1.36 tv 108:
1.35 thorpej 109: 20010915:
110: The new "ubcperf" code committed by Chuck Silvers removed
111: a header file, uvm/uvm_vnode.h. There may be stale .depend
112: files that still reference this file.
113:
114: Solution: "make cleandir && make dependall" in affected
115: directories.
1.31 enami 116:
117: 20010803:
118: grep.info is now built from grep.texi using makeinfo. Since it
119: requires makeinfo v4.0, you need to install new texinfo before
120: building gnu/usr.bin/grep. To install new texinfo, please follow
121: the instruction described in 20010726 entry.
1.30 enami 122:
123: 20010803:
1.41 wiz 124: (i386 only): i386 kernel now uses new instructions like
125: `fxsave' which old gas doesn't understand. To build the
1.52 wiz 126: kernel successfully, you need to build and install new gas
1.41 wiz 127: (gnu/usr.bin/gas.new), or (temporarily) comment out
128: "options I686_CPU" from your kernel configuration until you
129: rebuilt your userland (and got a new gas).
1.29 bjh21 130:
131: 20010731:
132: Bootloader update on ELF platforms. DDB in kernels from before
133: this will be unable to read symbol tables provided by newer
134: bootloaders.
1.27 assar 135:
136: 20010726:
137: Texinfo was updated to 4.0. To avoid failures when trying to
1.28 assar 138: build the included texinfo files, do:
139:
140: cd src/gnu/usr.bin/texinfo
141: make MKINFO=no dependall install
1.25 thorpej 142:
143: 20010718:
144: Enabled correct .init/.fini processing in crt0. The way this
145: was done was to change a -I directive to cc(1), which means
146: make(1) will have a stale dependency (it will be checking the
147: timestamp on the wrong "dot_init.h").
148:
149: The symptom you will see is that new programs die with SIGSEGV
150: if you have a stale dependency.
151:
152: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
153: before starting your build.
1.26 thorpej 154:
155: 20010628:
156: A construct was added to uvm_page.h that uncovered a bug
157: in lint(1). If you get a warning/error about a non-portable
158: bitfield, update your lint(1) before proceeding.
1.21 jmc 159:
160: 20010226:
1.22 jmc 161: Added named user/group to system. Need to hand add this in or builds
1.21 jmc 162: will break as mtree aborts early.
163:
164: To work around add by hand:
165:
166: named:*:14:
167:
1.22 jmc 168: to /etc/group and add:
169:
170: named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin
171:
172: to master.passwd (use vipw for instance if doing by hand).
173:
174: Now a make build should progress.
1.18 jmc 175:
176: 20010219:
1.52 wiz 177: get/setprogname() added. Any hostprogs that may use this will need
1.20 jmc 178: to be bootstrapped manually until the host system is current.
1.18 jmc 179:
180: Known problems: sys/arch/macppc/stand/fixcoff
1.19 cgd 181: usr.sbin/config (adding -DMAKE_BOOTSTRAP to
182: CFLAGS and rebuilding should work)
1.20 jmc 183: usr.sbin/mdsetimage - Build a static copy if
184: building a snapshot before fully bootstrapped.
1.15 christos 185:
186: 20010204:
187: prepare the code to compile with stricter gcc flags. in
188: particular start eliminating redundant declarations. Yacc
189: needs to be installed before make build.
1.10 christos 190:
191: 20010114:
192: introduce .if commands(target) in make(1). You need to
193: bring everything up-to-date first, then without installing
1.23 tron 194: anything make and install in usr.bin/make, then proceed
1.10 christos 195: with make build.
1.9 sommerfe 196:
197: 20010101:
198: bsd.subdir.mk committed 20001230 had a bug which caused
199: afterinstall targets to run too soon; update again.
1.8 sommerfe 200:
201: 20001230:
202: New share/mk files needed to support .WAIT in SUBDIR variables.
203: If you get make errors,
204: (cd share/mk; make install)
205: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 206:
207: 20001019:
1.7 ad 208: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 209: major and minor numbers haven't changed, you should update your /dev
210: directory.
1.1 abs 211:
1.4 itojun 212: 20000929:
213: The following make directives are obsoleted.
214: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
215: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 216: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 217: additional library libcrypto_{idea,rc5}.
1.1 abs 218:
219:
220: Hints for a more successful build:
221: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 222: Build a new kernel first:
223: This makes sure that any new system calls or features
224: expected by the new userland will be present. This
225: helps to avoid critical errors when upgrading.
1.1 abs 226: Use object directories:
227: This helps to keep stale object
228: files from polluting the build if a Makefile "forgets"
229: about one. It also makes it easier to clean up after
230: a build. It's also necessary if you want to use the
231: same source tree for multiple machines.
232: To use object directories:
233: a) cd /usr/src ; make cleandir
1.2 mrg 234: b) Add "OBJMACHINE=yes" to /etc/mk.conf
235: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 236: d) cd /usr/src ; make build
1.2 mrg 237: Note that running "make obj" in a directory will create
238: in obj.$MACHINE directory.
1.1 abs 239: Build to a DESTDIR:
240: This helps to keep old
241: installed files (especially libraries) from interfering
242: with the new build.
243: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 244: variable before running make build. It should be set to
245: the pathname of an initially empty directory.
1.1 abs 246: Problems: you might need to update critical utilities
247: without using DESTDIR since nothing is executed
248: from what is installed in DESTDIR.
249: (See critical utils, below)
250: Build often:
251: This keeps critical utilities current enough to not choke
252: on any other part of the source tree that depends on up to
253: date functionality.
254:
255: What to do if things don't work:
256: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
257: When things don't work there is usually a few things that commonly
258: should be done.
259: 1) make includes
260: This should be done automatically by make build.
261: 2) cd share/mk && make install
262: Again, automatically done by make build.
263:
264: Failsafe rebuild of a small part of the tree:
265: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
266: To make sure you rebuild something correctly you want to do
267: something like the following:
268: 1) Make sure the includes and .mk files are up to date.
269: 2) Make sure any program used to build the particular
270: utility is up to date. (yacc, lex, etc...)
271: 3) cd ...path/to/util...
272: make cleandir
273: rm ...all obj directories...
274: make cleandir # yes, again
275: make obj
276: make depend && make
277:
278: Failsafe rebuild of the entire tree:
279: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
280: If you really want to make sure the source tree is clean and
1.2 mrg 281: ready for a build try the following. Note that sourcing /etc/mk.conf
282: (a make(1) Makefile) in this manner is not right, and will not work
283: for anyone who uses any make(1) features in /etc/mk.conf.
1.1 abs 284:
