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.
5:
6: For a more detailed description see Makefile.

8: Recent changes:
9: ^^^^^^^^^^^^^^^
1.10 christos 10:
11: 20010114:
12: introduce .if commands(target) in make(1). You need to
13: bring everything up-to-date first, then without installing
14: anything make and install in /usr/bin/make, then proceed
15: with make build.
1.9 sommerfe 16:
17: 20010101:
18: bsd.subdir.mk committed 20001230 had a bug which caused
19: afterinstall targets to run too soon; update again.
1.8 sommerfe 20:
21: 20001230:
22: New share/mk files needed to support .WAIT in SUBDIR variables.
23: If you get make errors,
24: (cd share/mk; make install)
25: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 26:
27: 20001019:
1.7 ad 28: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 29: major and minor numbers haven't changed, you should update your /dev
30: directory.
1.1 abs 31:
1.4 itojun 32: 20000929:
33: The following make directives are obsoleted.
34: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
35: By default, RSA is built into libcrypto. IDEA and RC5 will not be
36: bulit into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
37: additional library libcrypto_{idea,rc5}.
38:
1.1 abs 39: 20000623:
40: MKCRYPTO and friends added to share/mk/bsd.own.mk.
41: 'cd share/mk ; make install' needed before make build.
42:
43:
44: Hints for a more successful build:
45: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 46: Build a new kernel first:
47: This makes sure that any new system calls or features
48: expected by the new userland will be present. This
49: helps to avoid critical errors when upgrading.
1.1 abs 50: Use object directories:
51: This helps to keep stale object
52: files from polluting the build if a Makefile "forgets"
53: about one. It also makes it easier to clean up after
54: a build. It's also necessary if you want to use the
55: same source tree for multiple machines.
56: To use object directories:
57: a) cd /usr/src ; make cleandir
1.2 mrg 58: b) Add "OBJMACHINE=yes" to /etc/mk.conf
59: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 60: d) cd /usr/src ; make build
1.2 mrg 61: Note that running "make obj" in a directory will create
62: in obj.$MACHINE directory.
1.1 abs 63: Build to a DESTDIR:
64: This helps to keep old
65: installed files (especially libraries) from interfering
66: with the new build.
67: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 68: variable before running make build. It should be set to
69: the pathname of an initially empty directory.
1.1 abs 70: Problems: you might need to update critical utilities
71: without using DESTDIR since nothing is executed
72: from what is installed in DESTDIR.
73: (See critical utils, below)
74: Build often:
75: This keeps critical utilities current enough to not choke
76: on any other part of the source tree that depends on up to
77: date functionality.
78:
79: What to do if things don't work:
80: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
81: When things don't work there is usually a few things that commonly
82: should be done.
83: 1) make includes
84: This should be done automatically by make build.
85: 2) cd share/mk && make install
86: Again, automatically done by make build.
87:
88: Failsafe rebuild of a small part of the tree:
89: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
90: To make sure you rebuild something correctly you want to do
91: something like the following:
92: 1) Make sure the includes and .mk files are up to date.
93: 2) Make sure any program used to build the particular
94: utility is up to date. (yacc, lex, etc...)
95: 3) cd ...path/to/util...
96: make cleandir
97: rm ...all obj directories...
98: make cleandir # yes, again
99: make obj
100: make depend && make
101:
102: Failsafe rebuild of the entire tree:
103: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
104: If you really want to make sure the source tree is clean and
1.2 mrg 105: ready for a build try the following. Note that sourcing /etc/mk.conf
106: (a make(1) Makefile) in this manner is not right, and will not work
107: for anyone who uses any make(1) features in /etc/mk.conf.
1.1 abs 108:
109: ---cut here---
110: #!/bin/sh
111: . /etc/mk.conf
112:
113: if [ -z $BSDSRCDIR ] ; then
114: BSDSRCDIR=/usr/src
115: fi
116: if [ \! -d $BSDSRCDIR ] ; then
117: echo Unable to find sources
118: exit 1
119: fi
120: find $BSDSRCDIR -name \*.o -o -name obj.\* -o -name obj -exec rm \{\} \;
121:
122: if [ -z $BSDOBJDIR ] ; then
123: BSDOBJDIR=/usr/obj
124: fi
125: if [ -d $BSDOBJDIR ] ; then
126: rm -rf $BSDOBJDIR
127: fi
128:
129: cd $BSDSRCDIR && make cleandir
130:
131: ---cut here---

133: Critical utilities:
134: ^^^^^^^^^^^^^^^^^^^
135: gnu/usr.bin/egcs
1.3 itojun 136: usr.bin/compile_et
1.1 abs 137: usr.bin/make
138: usr.bin/yacc

1.2 mrg 141: usr.sbin/config
1.1 abs 142:
143: Other problems and possibly solutions:
144: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
145: Symptom:Unreasonable compiler errors.
146: Fix: Rebuild gnu/usr.bin/egcs
147:
148: Symptom:Complaints involving a Makefile.
149: Fix: Make sure .mk files are up to date.
150: cd share/mk && make install
151: Fix: Rebuild usr.bin/make
1.2 mrg 152:
153: Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
154: Fix: Rebuild usr.sbin/config
1.1 abs 155:
156: Symptom:
157: Fix: Rebuild usr.bin/yacc
158:
159: Symptom:
160: Fix: Rebuild usr.bin/lex
161:
162: Symptom:
163: Fix: rm /usr/lib/libbfd.a
1.4 itojun 164:
165: Symptom:Obsolete intermediate files are used during compilation
166: Fix: Try the following sequence of commands in the directory in question.
167: make cleandir; rm `make print-objdir`; make cleandir; make obj
168: (If you built the tree without "make obj" in the past, obsolete files
169: may remain. The command tries to clean everything up)
1.5 wiz 170:
171: Symptom:.../sysinst/run.c:xx: warning: initialization from incompatible pointer type
172: Fix: Rebuild and install usr.bin/menuc
