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