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.

6: For a more detailed description see Makefile.

9: ^^^^^^^^^^^^^^^
1.46 ! thorpej 10: 20011128:
! 11: Kernel config information was changed to use defflag in
! 12: the various "files" files. Bug fixes to config(8) are
! 13: required in order for this to work properly. Make sure
! 14: to build and install in usr.sbin/config before attempting
! 15: to build a new kernel.
! 16:
1.45 yamt 17: 20011030:
18: libc/locale/wcstod.c now needs new lint(1). Update lint(1)
19: before building libc.
1.43 mason 20:
1.44 tv 21: 20011029:
22: The new document BUILDING.mdoc (view with nroff | more, or
23: see pre-generated .txt and .html versions) describes the build
24: procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
25: build process, are intended in the long run to replace this
26: manual update log.
27:
28: Users building a USE_NEW_TOOLCHAIN system should read the
29: BUILDING document for caveats. Generally, BUILDING supersedes
30: UPDATING for these systems, as tool updating is taken care of
31: by the new build system.
1.42 perry 32:
33: 20011028:
34: src/etc/Makefile now needs install to be able to handle
35: symlinks that point to nowhere. A bug in install that
36: prevented this was corrected.
37:
38: Solution: update and reinstall usr.bin/xinstall
39: Better Solution: Use the new toolchain and it will just work
40: for you.
1.40 lukem 41:
42: 20011006:
43: /etc/mtree/NetBSD.dist has been updated to take advantage of
44: absolute path support added to mtree(8). Older mtree(8)s don't
45: understand the format.
46:
47: Solution: update and reinstall usr.sbin/mtree
1.39 jmc 48:
49: 20011004:
50: Crunchgen has been updated to work via reach-over makefiles. Updating
51: is suggested before running a snapshot build
1.36 tv 52:
1.35 thorpej 53: 20010915:
54: The new "ubcperf" code committed by Chuck Silvers removed
55: a header file, uvm/uvm_vnode.h. There may be stale .depend
56: files that still reference this file.
57:
58: Solution: "make cleandir && make dependall" in affected
59: directories.
1.31 enami 60:
61: 20010803:
62: grep.info is now built from grep.texi using makeinfo. Since it
63: requires makeinfo v4.0, you need to install new texinfo before
64: building gnu/usr.bin/grep. To install new texinfo, please follow
65: the instruction described in 20010726 entry.
1.30 enami 66:
67: 20010803:
1.41 wiz 68: (i386 only): i386 kernel now uses new instructions like
69: `fxsave' which old gas doesn't understand. To build the
70: kernel successfuly, you need to build and install new gas
71: (gnu/usr.bin/gas.new), or (temporarily) comment out
72: "options I686_CPU" from your kernel configuration until you
73: rebuilt your userland (and got a new gas).
1.29 bjh21 74:
75: 20010731:
76: Bootloader update on ELF platforms. DDB in kernels from before
77: this will be unable to read symbol tables provided by newer
78: bootloaders.
1.27 assar 79:
80: 20010726:
81: Texinfo was updated to 4.0. To avoid failures when trying to
1.28 assar 82: build the included texinfo files, do:
83:
84: cd src/gnu/usr.bin/texinfo
85: make MKINFO=no dependall install
1.25 thorpej 86:
87: 20010718:
88: Enabled correct .init/.fini processing in crt0. The way this
89: was done was to change a -I directive to cc(1), which means
90: make(1) will have a stale dependency (it will be checking the
91: timestamp on the wrong "dot_init.h").
92:
93: The symptom you will see is that new programs die with SIGSEGV
94: if you have a stale dependency.
95:
96: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
97: before starting your build.
1.26 thorpej 98:
99: 20010628:
100: A construct was added to uvm_page.h that uncovered a bug
101: in lint(1). If you get a warning/error about a non-portable
102: bitfield, update your lint(1) before proceeding.
1.21 jmc 103:
104: 20010226:
1.22 jmc 105: Added named user/group to system. Need to hand add this in or builds
1.21 jmc 106: will break as mtree aborts early.
107:
108: To work around add by hand:
109:
110: named:*:14:
111:
1.22 jmc 112: to /etc/group and add:
113:
114: named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin
115:
116: to master.passwd (use vipw for instance if doing by hand).
117:
118: Now a make build should progress.
1.18 jmc 119:
120: 20010219:
121: get/setprogname() added. Any hostprog's that may use this will need
1.20 jmc 122: to be bootstrapped manually until the host system is current.
1.18 jmc 123:
124: Known problems: sys/arch/macppc/stand/fixcoff
1.19 cgd 125: usr.sbin/config (adding -DMAKE_BOOTSTRAP to
126: CFLAGS and rebuilding should work)
1.20 jmc 127: usr.sbin/mdsetimage - Build a static copy if
128: building a snapshot before fully bootstrapped.
1.15 christos 129:
130: 20010204:
131: prepare the code to compile with stricter gcc flags. in
132: particular start eliminating redundant declarations. Yacc
133: needs to be installed before make build.
1.10 christos 134:
135: 20010114:
136: introduce .if commands(target) in make(1). You need to
137: bring everything up-to-date first, then without installing
1.23 tron 138: anything make and install in usr.bin/make, then proceed
1.10 christos 139: with make build.
1.9 sommerfe 140:
141: 20010101:
142: bsd.subdir.mk committed 20001230 had a bug which caused
143: afterinstall targets to run too soon; update again.
1.8 sommerfe 144:
145: 20001230:
146: New share/mk files needed to support .WAIT in SUBDIR variables.
147: If you get make errors,
148: (cd share/mk; make install)
149: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 150:
151: 20001019:
1.7 ad 152: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 153: major and minor numbers haven't changed, you should update your /dev
154: directory.
1.1 abs 155:
1.4 itojun 156: 20000929:
157: The following make directives are obsoleted.
158: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
159: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 160: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 161: additional library libcrypto_{idea,rc5}.
1.1 abs 162:
163:
164: Hints for a more successful build:
165: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 166: Build a new kernel first:
167: This makes sure that any new system calls or features
168: expected by the new userland will be present. This
169: helps to avoid critical errors when upgrading.
1.1 abs 170: Use object directories:
171: This helps to keep stale object
172: files from polluting the build if a Makefile "forgets"
173: about one. It also makes it easier to clean up after
174: a build. It's also necessary if you want to use the
175: same source tree for multiple machines.
176: To use object directories:
177: a) cd /usr/src ; make cleandir
1.2 mrg 178: b) Add "OBJMACHINE=yes" to /etc/mk.conf
179: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 180: d) cd /usr/src ; make build
1.2 mrg 181: Note that running "make obj" in a directory will create
182: in obj.$MACHINE directory.
1.1 abs 183: Build to a DESTDIR:
184: This helps to keep old
185: installed files (especially libraries) from interfering
186: with the new build.
187: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 188: variable before running make build. It should be set to
189: the pathname of an initially empty directory.
1.1 abs 190: Problems: you might need to update critical utilities
191: without using DESTDIR since nothing is executed
192: from what is installed in DESTDIR.
193: (See critical utils, below)
194: Build often:
195: This keeps critical utilities current enough to not choke
196: on any other part of the source tree that depends on up to
197: date functionality.
198:
199: What to do if things don't work:
200: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
201: When things don't work there is usually a few things that commonly
202: should be done.
203: 1) make includes
204: This should be done automatically by make build.
205: 2) cd share/mk && make install
206: Again, automatically done by make build.
207:
208: Failsafe rebuild of a small part of the tree:
209: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
210: To make sure you rebuild something correctly you want to do
211: something like the following:
212: 1) Make sure the includes and .mk files are up to date.
213: 2) Make sure any program used to build the particular
214: utility is up to date. (yacc, lex, etc...)
215: 3) cd ...path/to/util...
216: make cleandir
217: rm ...all obj directories...
218: make cleandir # yes, again
219: make obj
220: make depend && make
221:
222: Failsafe rebuild of the entire tree:
223: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
224: If you really want to make sure the source tree is clean and
1.2 mrg 225: ready for a build try the following. Note that sourcing /etc/mk.conf
226: (a make(1) Makefile) in this manner is not right, and will not work
227: for anyone who uses any make(1) features in /etc/mk.conf.
1.1 abs 228:
229: ---cut here---
230: #!/bin/sh
231: . /etc/mk.conf

234: BSDSRCDIR=/usr/src

236: if [ \! -d $BSDSRCDIR ] ; then
237: echo Unable to find sources
238: exit 1
239: fi
240: find $BSDSRCDIR -name \*.o -o -name obj.\* -o -name obj -exec rm \{\} \;

268: Symptom:Complaints involving a Makefile.
1.17 erh 269: Fix: Rebuild usr.bin/make:

271: Or, a failsafe method if that doesn't work:
272: cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
273:
1.1 abs 274: Fix: Make sure .mk files are up to date.

1.4 itojun 288:
289: Symptom:Obsolete intermediate files are used during compilation
290: Fix: Try the following sequence of commands in the directory in question.
291: make cleandir; rm `make print-objdir`; make cleandir; make obj
292: (If you built the tree without "make obj" in the past, obsolete files
293: may remain. The command tries to clean everything up)
