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.
7:
8: Recent changes:
9: ^^^^^^^^^^^^^^^
1.8 ! sommerfe 10:
! 11: 20001230:
! 12: New share/mk files needed to support .WAIT in SUBDIR variables.
! 13: If you get make errors,
! 14: (cd share/mk; make install)
! 15: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 16:
17: 20001019:
1.7 ad 18: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 19: major and minor numbers haven't changed, you should update your /dev
20: directory.
1.1 abs 21:
1.4 itojun 22: 20000929:
23: The following make directives are obsoleted.
24: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
25: By default, RSA is built into libcrypto. IDEA and RC5 will not be
26: bulit into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
27: additional library libcrypto_{idea,rc5}.
28:
1.1 abs 29: 20000623:
30: MKCRYPTO and friends added to share/mk/bsd.own.mk.
31: 'cd share/mk ; make install' needed before make build.
32:
33:
34: Hints for a more successful build:
35: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 36: Build a new kernel first:
37: This makes sure that any new system calls or features
38: expected by the new userland will be present. This
39: helps to avoid critical errors when upgrading.
1.1 abs 40: Use object directories:
41: This helps to keep stale object
42: files from polluting the build if a Makefile "forgets"
43: about one. It also makes it easier to clean up after
44: a build. It's also necessary if you want to use the
45: same source tree for multiple machines.
46: To use object directories:
47: a) cd /usr/src ; make cleandir
1.2 mrg 48: b) Add "OBJMACHINE=yes" to /etc/mk.conf
49: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 50: d) cd /usr/src ; make build
1.2 mrg 51: Note that running "make obj" in a directory will create
52: in obj.$MACHINE directory.
1.1 abs 53: Build to a DESTDIR:
54: This helps to keep old
55: installed files (especially libraries) from interfering
56: with the new build.
57: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 58: variable before running make build. It should be set to
59: the pathname of an initially empty directory.
1.1 abs 60: Problems: you might need to update critical utilities
61: without using DESTDIR since nothing is executed
62: from what is installed in DESTDIR.
63: (See critical utils, below)
64: Build often:
65: This keeps critical utilities current enough to not choke
66: on any other part of the source tree that depends on up to
67: date functionality.
68:
69: What to do if things don't work:
70: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
71: When things don't work there is usually a few things that commonly
72: should be done.
73: 1) make includes
74: This should be done automatically by make build.
75: 2) cd share/mk && make install
76: Again, automatically done by make build.
77:
78: Failsafe rebuild of a small part of the tree:
79: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
80: To make sure you rebuild something correctly you want to do
81: something like the following:
82: 1) Make sure the includes and .mk files are up to date.
83: 2) Make sure any program used to build the particular
84: utility is up to date. (yacc, lex, etc...)
85: 3) cd ...path/to/util...
86: make cleandir
87: rm ...all obj directories...
88: make cleandir # yes, again
89: make obj
90: make depend && make
91:
92: Failsafe rebuild of the entire tree:
93: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
94: If you really want to make sure the source tree is clean and
1.2 mrg 95: ready for a build try the following. Note that sourcing /etc/mk.conf
96: (a make(1) Makefile) in this manner is not right, and will not work
97: for anyone who uses any make(1) features in /etc/mk.conf.
1.1 abs 98:
99: ---cut here---
100: #!/bin/sh
101: . /etc/mk.conf

104: BSDSRCDIR=/usr/src
105: fi
106: if [ \! -d $BSDSRCDIR ] ; then
107: echo Unable to find sources
108: exit 1
109: fi
110: find $BSDSRCDIR -name \*.o -o -name obj.\* -o -name obj -exec rm \{\} \;

112: if [ -z $BSDOBJDIR ] ; then
113: BSDOBJDIR=/usr/obj

115: if [ -d $BSDOBJDIR ] ; then
116: rm -rf $BSDOBJDIR
117: fi

119: cd $BSDSRCDIR && make cleandir

123: Critical utilities:
124: ^^^^^^^^^^^^^^^^^^^
125: gnu/usr.bin/egcs
1.3 itojun 126: usr.bin/compile_et
1.1 abs 127: usr.bin/make
128: usr.bin/yacc
129: usr.bin/lex
1.2 mrg 130: usr.sbin/config
1.1 abs 131:
132: Other problems and possibly solutions:
133: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
134: Symptom:Unreasonable compiler errors.
135: Fix: Rebuild gnu/usr.bin/egcs
136:
137: Symptom:Complaints involving a Makefile.
138: Fix: Make sure .mk files are up to date.
139: cd share/mk && make install
140: Fix: Rebuild usr.bin/make
1.2 mrg 141:
142: Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
143: Fix: Rebuild usr.sbin/config
1.1 abs 144:
145: Symptom:
146: Fix: Rebuild usr.bin/yacc
147:
148: Symptom:
149: Fix: Rebuild usr.bin/lex
150:
151: Symptom:
152: Fix: rm /usr/lib/libbfd.a
1.4 itojun 153:
154: Symptom:Obsolete intermediate files are used during compilation
155: Fix: Try the following sequence of commands in the directory in question.
156: make cleandir; rm `make print-objdir`; make cleandir; make obj
157: (If you built the tree without "make obj" in the past, obsolete files
158: may remain. The command tries to clean everything up)
1.5 wiz 159:
160: Symptom:.../sysinst/run.c:xx: warning: initialization from incompatible pointer type
161: Fix: Rebuild and install usr.bin/menuc
