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: ^^^^^^^^^^^^^^^
1.18 jmc 10:
11: 20010219:
12: get/setprogname() added. Any hostprog's that may use this will need
13: to be bootstraped manually until the host system is current.
14:
15: Known problems: sys/arch/macppc/stand/fixcoff
1.19 ! cgd 16: usr.sbin/config (adding -DMAKE_BOOTSTRAP to
! 17: CFLAGS and rebuilding should work)
1.15 christos 18:
19: 20010204:
20: prepare the code to compile with stricter gcc flags. in
21: particular start eliminating redundant declarations. Yacc
22: needs to be installed before make build.
1.10 christos 23:
24: 20010114:
25: introduce .if commands(target) in make(1). You need to
26: bring everything up-to-date first, then without installing
27: anything make and install in /usr/bin/make, then proceed
28: with make build.
1.9 sommerfe 29:
30: 20010101:
31: bsd.subdir.mk committed 20001230 had a bug which caused
32: afterinstall targets to run too soon; update again.
1.8 sommerfe 33:
34: 20001230:
35: New share/mk files needed to support .WAIT in SUBDIR variables.
36: If you get make errors,
37: (cd share/mk; make install)
38: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 39:
40: 20001019:
1.7 ad 41: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 42: major and minor numbers haven't changed, you should update your /dev
43: directory.
1.1 abs 44:
1.4 itojun 45: 20000929:
46: The following make directives are obsoleted.
47: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
48: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 49: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 50: additional library libcrypto_{idea,rc5}.
51:
1.1 abs 52: 20000623:
53: MKCRYPTO and friends added to share/mk/bsd.own.mk.
54: 'cd share/mk ; make install' needed before make build.
55:
56:
57: Hints for a more successful build:
58: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 59: Build a new kernel first:
60: This makes sure that any new system calls or features
61: expected by the new userland will be present. This
62: helps to avoid critical errors when upgrading.
1.1 abs 63: Use object directories:
64: This helps to keep stale object
65: files from polluting the build if a Makefile "forgets"
66: about one. It also makes it easier to clean up after
67: a build. It's also necessary if you want to use the
68: same source tree for multiple machines.
69: To use object directories:
70: a) cd /usr/src ; make cleandir
1.2 mrg 71: b) Add "OBJMACHINE=yes" to /etc/mk.conf
72: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 73: d) cd /usr/src ; make build
1.2 mrg 74: Note that running "make obj" in a directory will create
75: in obj.$MACHINE directory.
1.1 abs 76: Build to a DESTDIR:
77: This helps to keep old
78: installed files (especially libraries) from interfering
79: with the new build.
80: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 81: variable before running make build. It should be set to
82: the pathname of an initially empty directory.
1.1 abs 83: Problems: you might need to update critical utilities
84: without using DESTDIR since nothing is executed
85: from what is installed in DESTDIR.
86: (See critical utils, below)
87: Build often:
88: This keeps critical utilities current enough to not choke
89: on any other part of the source tree that depends on up to
90: date functionality.
91:
92: What to do if things don't work:
93: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
94: When things don't work there is usually a few things that commonly
95: should be done.
96: 1) make includes
97: This should be done automatically by make build.
98: 2) cd share/mk && make install
99: Again, automatically done by make build.
100:
101: Failsafe rebuild of a small part of the tree:
102: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
103: To make sure you rebuild something correctly you want to do
104: something like the following:
105: 1) Make sure the includes and .mk files are up to date.
106: 2) Make sure any program used to build the particular
107: utility is up to date. (yacc, lex, etc...)
108: 3) cd ...path/to/util...
109: make cleandir
110: rm ...all obj directories...
111: make cleandir # yes, again
112: make obj
113: make depend && make
114:
115: Failsafe rebuild of the entire tree:
116: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
117: If you really want to make sure the source tree is clean and
1.2 mrg 118: ready for a build try the following. Note that sourcing /etc/mk.conf
119: (a make(1) Makefile) in this manner is not right, and will not work
120: for anyone who uses any make(1) features in /etc/mk.conf.
1.1 abs 121:
122: ---cut here---
123: #!/bin/sh
124: . /etc/mk.conf
125:
126: if [ -z $BSDSRCDIR ] ; then
127: BSDSRCDIR=/usr/src
128: fi
129: if [ \! -d $BSDSRCDIR ] ; then
130: echo Unable to find sources
131: exit 1
132: fi
133: find $BSDSRCDIR -name \*.o -o -name obj.\* -o -name obj -exec rm \{\} \;
134:
135: if [ -z $BSDOBJDIR ] ; then
136: BSDOBJDIR=/usr/obj
137: fi
138: if [ -d $BSDOBJDIR ] ; then
139: rm -rf $BSDOBJDIR
140: fi
141:
142: cd $BSDSRCDIR && make cleandir
143:
144: ---cut here---

146: Critical utilities:
147: ^^^^^^^^^^^^^^^^^^^
148: gnu/usr.bin/egcs
1.3 itojun 149: usr.bin/compile_et
1.1 abs 150: usr.bin/make
151: usr.bin/yacc
152: usr.bin/lex
1.11 lukem 153: usr.bin/xlint
1.2 mrg 154: usr.sbin/config
1.1 abs 155:
156: Other problems and possibly solutions:
157: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
158: Symptom:Unreasonable compiler errors.
159: Fix: Rebuild gnu/usr.bin/egcs
160:
161: Symptom:Complaints involving a Makefile.
1.17 erh 162: Fix: Rebuild usr.bin/make:
163: cd usr.bin/make && make && make install
164: Or, a failsafe method if that doesn't work:
165: cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
166:
1.1 abs 167: Fix: Make sure .mk files are up to date.
168: cd share/mk && make install
1.2 mrg 169:
170: Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
171: Fix: Rebuild usr.sbin/config
1.1 abs 172:
173: Symptom:
174: Fix: Rebuild usr.bin/yacc
175:
176: Symptom:
177: Fix: Rebuild usr.bin/lex
178:
179: Symptom:
180: Fix: rm /usr/lib/libbfd.a
1.4 itojun 181:
182: Symptom:Obsolete intermediate files are used during compilation
183: Fix: Try the following sequence of commands in the directory in question.
184: make cleandir; rm `make print-objdir`; make cleandir; make obj
185: (If you built the tree without "make obj" in the past, obsolete files
186: may remain. The command tries to clean everything up)
1.5 wiz 187:
188: Symptom:.../sysinst/run.c:xx: warning: initialization from incompatible pointer type
189: Fix: Rebuild and install usr.bin/menuc
1.12 itojun 190:

194: Symptom:undefined reference to `__assert13'
195: Fix: Rebuild and install lib/libc
196:
1.19 ! cgd 197: Symptom:usr.sbin/config fails to build.
! 198: Fix: Try building with -DMAKE_BOOTSTRAP added to CFLAGS in Makefile.
