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.

8: Recent changes:
9: ^^^^^^^^^^^^^^^
1.15 christos 10:
11: 20010204:
12: prepare the code to compile with stricter gcc flags. in
13: particular start eliminating redundant declarations. Yacc
14: needs to be installed before make build.
1.10 christos 15:
16: 20010114:
17: introduce .if commands(target) in make(1). You need to
18: bring everything up-to-date first, then without installing
19: anything make and install in /usr/bin/make, then proceed
20: with make build.
1.9 sommerfe 21:
22: 20010101:
23: bsd.subdir.mk committed 20001230 had a bug which caused
24: afterinstall targets to run too soon; update again.
1.8 sommerfe 25:
26: 20001230:
27: New share/mk files needed to support .WAIT in SUBDIR variables.
28: If you get make errors,
29: (cd share/mk; make install)
30: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 31:
32: 20001019:
1.7 ad 33: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 34: major and minor numbers haven't changed, you should update your /dev
35: directory.
1.1 abs 36:
1.4 itojun 37: 20000929:
38: The following make directives are obsoleted.
39: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
40: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 41: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 42: additional library libcrypto_{idea,rc5}.
43:
1.1 abs 44: 20000623:
45: MKCRYPTO and friends added to share/mk/bsd.own.mk.
46: 'cd share/mk ; make install' needed before make build.
47:

49: Hints for a more successful build:
50: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 51: Build a new kernel first:
52: This makes sure that any new system calls or features
53: expected by the new userland will be present. This
54: helps to avoid critical errors when upgrading.
1.1 abs 55: Use object directories:
56: This helps to keep stale object
57: files from polluting the build if a Makefile "forgets"
58: about one. It also makes it easier to clean up after
59: a build. It's also necessary if you want to use the
60: same source tree for multiple machines.
61: To use object directories:
62: a) cd /usr/src ; make cleandir
1.2 mrg 63: b) Add "OBJMACHINE=yes" to /etc/mk.conf
64: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 65: d) cd /usr/src ; make build
1.2 mrg 66: Note that running "make obj" in a directory will create
67: in obj.$MACHINE directory.
1.1 abs 68: Build to a DESTDIR:
69: This helps to keep old
70: installed files (especially libraries) from interfering
71: with the new build.
72: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 73: variable before running make build. It should be set to
74: the pathname of an initially empty directory.
1.1 abs 75: Problems: you might need to update critical utilities
76: without using DESTDIR since nothing is executed
77: from what is installed in DESTDIR.
78: (See critical utils, below)
79: Build often:
80: This keeps critical utilities current enough to not choke
81: on any other part of the source tree that depends on up to
82: date functionality.
83:
84: What to do if things don't work:
85: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
86: When things don't work there is usually a few things that commonly
87: should be done.
88: 1) make includes
89: This should be done automatically by make build.
90: 2) cd share/mk && make install
91: Again, automatically done by make build.
92:
93: Failsafe rebuild of a small part of the tree:
94: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
95: To make sure you rebuild something correctly you want to do
96: something like the following:
97: 1) Make sure the includes and .mk files are up to date.
98: 2) Make sure any program used to build the particular
99: utility is up to date. (yacc, lex, etc...)
100: 3) cd ...path/to/util...
101: make cleandir
102: rm ...all obj directories...
103: make cleandir # yes, again
104: make obj
105: make depend && make
106:
107: Failsafe rebuild of the entire tree:
108: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
109: If you really want to make sure the source tree is clean and
1.2 mrg 110: ready for a build try the following. Note that sourcing /etc/mk.conf
111: (a make(1) Makefile) in this manner is not right, and will not work
112: for anyone who uses any make(1) features in /etc/mk.conf.
1.1 abs 113:
114: ---cut here---
115: #!/bin/sh
116: . /etc/mk.conf

119: BSDSRCDIR=/usr/src
120: fi
121: if [ \! -d $BSDSRCDIR ] ; then
122: echo Unable to find sources
123: exit 1
124: fi
125: find $BSDSRCDIR -name \*.o -o -name obj.\* -o -name obj -exec rm \{\} \;

132: fi

139: ^^^^^^^^^^^^^^^^^^^
140: gnu/usr.bin/egcs
1.3 itojun 141: usr.bin/compile_et
1.1 abs 142: usr.bin/make
143: usr.bin/yacc

1.11 lukem 145: usr.bin/xlint
1.2 mrg 146: usr.sbin/config
1.1 abs 147:
148: Other problems and possibly solutions:
149: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
150: Symptom:Unreasonable compiler errors.
151: Fix: Rebuild gnu/usr.bin/egcs
152:
153: Symptom:Complaints involving a Makefile.
1.17 ! erh 154: Fix: Rebuild usr.bin/make:
! 155: cd usr.bin/make && make && make install
! 156: Or, a failsafe method if that doesn't work:
! 157: cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
! 158:
1.1 abs 159: Fix: Make sure .mk files are up to date.
160: cd share/mk && make install
1.2 mrg 161:
162: Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
163: Fix: Rebuild usr.sbin/config
1.1 abs 164:
165: Symptom:
166: Fix: Rebuild usr.bin/yacc
167:
168: Symptom:
169: Fix: Rebuild usr.bin/lex
170:
171: Symptom:
172: Fix: rm /usr/lib/libbfd.a
1.4 itojun 173:
174: Symptom:Obsolete intermediate files are used during compilation
175: Fix: Try the following sequence of commands in the directory in question.
176: make cleandir; rm `make print-objdir`; make cleandir; make obj
177: (If you built the tree without "make obj" in the past, obsolete files
178: may remain. The command tries to clean everything up)

180: Symptom:.../sysinst/run.c:xx: warning: initialization from incompatible pointer type
181: Fix: Rebuild and install usr.bin/menuc
1.12 itojun 182:

184: Fix: Build and install usr.bin/mklocale
1.13 dogcow 185:
186: Symptom:undefined reference to `__assert13'
