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: ^^^^^^^^^^^^^^^
1.6 ! ad 10:
! 11: 20001019:
! 12: The `ca' device driver has been replaced by `lsu'; although the
! 13: major and minor numbers haven't changed, you should update your /dev
! 14: directory.
1.1 abs 15:
1.4 itojun 16: 20000929:
17: The following make directives are obsoleted.
18: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
19: By default, RSA is built into libcrypto. IDEA and RC5 will not be
20: bulit into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
21: additional library libcrypto_{idea,rc5}.
22:
1.1 abs 23: 20000623:
24: MKCRYPTO and friends added to share/mk/bsd.own.mk.
25: 'cd share/mk ; make install' needed before make build.

28: Hints for a more successful build:
29: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 30: Build a new kernel first:
31: This makes sure that any new system calls or features
32: expected by the new userland will be present. This
33: helps to avoid critical errors when upgrading.
1.1 abs 34: Use object directories:
35: This helps to keep stale object
36: files from polluting the build if a Makefile "forgets"
37: about one. It also makes it easier to clean up after
38: a build. It's also necessary if you want to use the
39: same source tree for multiple machines.
40: To use object directories:
41: a) cd /usr/src ; make cleandir
1.2 mrg 42: b) Add "OBJMACHINE=yes" to /etc/mk.conf
43: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 44: d) cd /usr/src ; make build
1.2 mrg 45: Note that running "make obj" in a directory will create
46: in obj.$MACHINE directory.
1.1 abs 47: Build to a DESTDIR:
48: This helps to keep old
49: installed files (especially libraries) from interfering
50: with the new build.
51: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 52: variable before running make build. It should be set to
53: the pathname of an initially empty directory.
1.1 abs 54: Problems: you might need to update critical utilities
55: without using DESTDIR since nothing is executed
56: from what is installed in DESTDIR.
57: (See critical utils, below)
58: Build often:
59: This keeps critical utilities current enough to not choke
60: on any other part of the source tree that depends on up to
61: date functionality.
62:
63: What to do if things don't work:
64: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
65: When things don't work there is usually a few things that commonly
66: should be done.
67: 1) make includes
68: This should be done automatically by make build.
69: 2) cd share/mk && make install
70: Again, automatically done by make build.
71:
72: Failsafe rebuild of a small part of the tree:
73: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
74: To make sure you rebuild something correctly you want to do
75: something like the following:
76: 1) Make sure the includes and .mk files are up to date.
77: 2) Make sure any program used to build the particular
78: utility is up to date. (yacc, lex, etc...)
79: 3) cd ...path/to/util...
80: make cleandir
81: rm ...all obj directories...
82: make cleandir # yes, again
83: make obj
84: make depend && make
85:
86: Failsafe rebuild of the entire tree:
87: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
88: If you really want to make sure the source tree is clean and
1.2 mrg 89: ready for a build try the following. Note that sourcing /etc/mk.conf
90: (a make(1) Makefile) in this manner is not right, and will not work
91: for anyone who uses any make(1) features in /etc/mk.conf.

117: Critical utilities:
118: ^^^^^^^^^^^^^^^^^^^
119: gnu/usr.bin/egcs
1.3 itojun 120: usr.bin/compile_et
1.1 abs 121: usr.bin/make
122: usr.bin/yacc
123: usr.bin/lex
1.2 mrg 124: usr.sbin/config
1.1 abs 125:
126: Other problems and possibly solutions:
127: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
128: Symptom:Unreasonable compiler errors.
129: Fix: Rebuild gnu/usr.bin/egcs
130:
131: Symptom:Complaints involving a Makefile.
132: Fix: Make sure .mk files are up to date.
133: cd share/mk && make install
134: Fix: Rebuild usr.bin/make
1.2 mrg 135:
136: Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
137: Fix: Rebuild usr.sbin/config
1.1 abs 138:
139: Symptom:
140: Fix: Rebuild usr.bin/yacc
141:
142: Symptom:
143: Fix: Rebuild usr.bin/lex
144:
145: Symptom:
146: Fix: rm /usr/lib/libbfd.a
1.4 itojun 147:
148: Symptom:Obsolete intermediate files are used during compilation
149: Fix: Try the following sequence of commands in the directory in question.
150: make cleandir; rm `make print-objdir`; make cleandir; make obj
151: (If you built the tree without "make obj" in the past, obsolete files
152: may remain. The command tries to clean everything up)
1.5 wiz 153:
154: Symptom:.../sysinst/run.c:xx: warning: initialization from incompatible pointer type
155: Fix: Rebuild and install usr.bin/menuc
