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.

8: Recent changes:
9: ^^^^^^^^^^^^^^^
10:
1.4 itojun 11: 20000929:
12: The following make directives are obsoleted.
13: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
14: By default, RSA is built into libcrypto. IDEA and RC5 will not be
15: bulit into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
16: additional library libcrypto_{idea,rc5}.
17:
1.1 abs 18: 20000623:
19: MKCRYPTO and friends added to share/mk/bsd.own.mk.
20: 'cd share/mk ; make install' needed before make build.
21:
22:
23: Hints for a more successful build:
24: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 25: Build a new kernel first:
26: This makes sure that any new system calls or features
27: expected by the new userland will be present. This
28: helps to avoid critical errors when upgrading.
1.1 abs 29: Use object directories:
30: This helps to keep stale object
31: files from polluting the build if a Makefile "forgets"
32: about one. It also makes it easier to clean up after
33: a build. It's also necessary if you want to use the
34: same source tree for multiple machines.
35: To use object directories:
36: a) cd /usr/src ; make cleandir
1.2 mrg 37: b) Add "OBJMACHINE=yes" to /etc/mk.conf
38: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 39: d) cd /usr/src ; make build
1.2 mrg 40: Note that running "make obj" in a directory will create
41: in obj.$MACHINE directory.
1.1 abs 42: Build to a DESTDIR:
43: This helps to keep old
44: installed files (especially libraries) from interfering
45: with the new build.
46: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 47: variable before running make build. It should be set to
48: the pathname of an initially empty directory.
1.1 abs 49: Problems: you might need to update critical utilities
50: without using DESTDIR since nothing is executed
51: from what is installed in DESTDIR.
52: (See critical utils, below)
53: Build often:
54: This keeps critical utilities current enough to not choke
55: on any other part of the source tree that depends on up to
56: date functionality.
57:
58: What to do if things don't work:
59: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
60: When things don't work there is usually a few things that commonly
61: should be done.
62: 1) make includes
63: This should be done automatically by make build.
64: 2) cd share/mk && make install
65: Again, automatically done by make build.
66:
67: Failsafe rebuild of a small part of the tree:
68: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
69: To make sure you rebuild something correctly you want to do
70: something like the following:
71: 1) Make sure the includes and .mk files are up to date.
72: 2) Make sure any program used to build the particular
73: utility is up to date. (yacc, lex, etc...)
74: 3) cd ...path/to/util...
75: make cleandir
76: rm ...all obj directories...
77: make cleandir # yes, again
78: make obj
79: make depend && make
80:
81: Failsafe rebuild of the entire tree:
82: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
83: If you really want to make sure the source tree is clean and
1.2 mrg 84: ready for a build try the following. Note that sourcing /etc/mk.conf
85: (a make(1) Makefile) in this manner is not right, and will not work
86: for anyone who uses any make(1) features in /etc/mk.conf.

112: Critical utilities:
113: ^^^^^^^^^^^^^^^^^^^
114: gnu/usr.bin/egcs
1.3 itojun 115: usr.bin/compile_et
1.1 abs 116: usr.bin/make
117: usr.bin/yacc
118: usr.bin/lex
1.2 mrg 119: usr.sbin/config
1.1 abs 120:
121: Other problems and possibly solutions:
122: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
123: Symptom:Unreasonable compiler errors.
124: Fix: Rebuild gnu/usr.bin/egcs
125:
126: Symptom:Complaints involving a Makefile.
127: Fix: Make sure .mk files are up to date.
128: cd share/mk && make install
129: Fix: Rebuild usr.bin/make
1.2 mrg 130:
131: Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
132: Fix: Rebuild usr.sbin/config
1.1 abs 133:
134: Symptom:
135: Fix: Rebuild usr.bin/yacc
136:
137: Symptom:
138: Fix: Rebuild usr.bin/lex
139:
140: Symptom:
141: Fix: rm /usr/lib/libbfd.a
1.4 itojun 142:
143: Symptom:Obsolete intermediate files are used during compilation
144: Fix: Try the following sequence of commands in the directory in question.
145: make cleandir; rm `make print-objdir`; make cleandir; make obj
146: (If you built the tree without "make obj" in the past, obsolete files
147: may remain. The command tries to clean everything up)
1.5 ! wiz 148:
! 149: Symptom:.../sysinst/run.c:xx: warning: initialization from incompatible pointer type
! 150: Fix: Rebuild and install usr.bin/menuc
