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: ^^^^^^^^^^^^^^^
1.21 jmc 10:
11: 20010226:
12:
1.22 jmc 13: Added named user/group to system. Need to hand add this in or builds
1.21 jmc 14: will break as mtree aborts early.
15:
16: To work around add by hand:
17:
18: named:*:14:
19:
1.22 jmc 20: to /etc/group and add:
21:
22: named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin
23:
24: to master.passwd (use vipw for instance if doing by hand).
25:
26: Now a make build should progress.
1.18 jmc 27:
28: 20010219:
29: get/setprogname() added. Any hostprog's that may use this will need
1.20 jmc 30: to be bootstrapped manually until the host system is current.
1.18 jmc 31:
32: Known problems: sys/arch/macppc/stand/fixcoff
1.19 cgd 33: usr.sbin/config (adding -DMAKE_BOOTSTRAP to
34: CFLAGS and rebuilding should work)
1.20 jmc 35: usr.sbin/mdsetimage - Build a static copy if
36: building a snapshot before fully bootstrapped.
1.15 christos 37:
38: 20010204:
39: prepare the code to compile with stricter gcc flags. in
40: particular start eliminating redundant declarations. Yacc
41: needs to be installed before make build.
1.10 christos 42:
43: 20010114:
44: introduce .if commands(target) in make(1). You need to
45: bring everything up-to-date first, then without installing
1.23 tron 46: anything make and install in usr.bin/make, then proceed
1.10 christos 47: with make build.
1.9 sommerfe 48:
49: 20010101:
50: bsd.subdir.mk committed 20001230 had a bug which caused
51: afterinstall targets to run too soon; update again.
1.8 sommerfe 52:
53: 20001230:
54: New share/mk files needed to support .WAIT in SUBDIR variables.
55: If you get make errors,
56: (cd share/mk; make install)
57: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 58:
59: 20001019:
1.7 ad 60: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 61: major and minor numbers haven't changed, you should update your /dev
62: directory.
1.1 abs 63:
1.4 itojun 64: 20000929:
65: The following make directives are obsoleted.
66: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
67: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 68: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 69: additional library libcrypto_{idea,rc5}.
70:
1.1 abs 71: 20000623:
72: MKCRYPTO and friends added to share/mk/bsd.own.mk.
73: 'cd share/mk ; make install' needed before make build.
74:
75:
76: Hints for a more successful build:
77: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 78: Build a new kernel first:
79: This makes sure that any new system calls or features
80: expected by the new userland will be present. This
81: helps to avoid critical errors when upgrading.
1.1 abs 82: Use object directories:
83: This helps to keep stale object
84: files from polluting the build if a Makefile "forgets"
85: about one. It also makes it easier to clean up after
86: a build. It's also necessary if you want to use the
87: same source tree for multiple machines.
88: To use object directories:
89: a) cd /usr/src ; make cleandir
1.2 mrg 90: b) Add "OBJMACHINE=yes" to /etc/mk.conf
91: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 92: d) cd /usr/src ; make build
1.2 mrg 93: Note that running "make obj" in a directory will create
94: in obj.$MACHINE directory.
1.1 abs 95: Build to a DESTDIR:
96: This helps to keep old
97: installed files (especially libraries) from interfering
98: with the new build.
99: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 100: variable before running make build. It should be set to
101: the pathname of an initially empty directory.
1.1 abs 102: Problems: you might need to update critical utilities
103: without using DESTDIR since nothing is executed
104: from what is installed in DESTDIR.
105: (See critical utils, below)
106: Build often:
107: This keeps critical utilities current enough to not choke
108: on any other part of the source tree that depends on up to
109: date functionality.
110:
111: What to do if things don't work:
112: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
113: When things don't work there is usually a few things that commonly
114: should be done.
115: 1) make includes
116: This should be done automatically by make build.
117: 2) cd share/mk && make install
118: Again, automatically done by make build.
119:
120: Failsafe rebuild of a small part of the tree:
121: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
122: To make sure you rebuild something correctly you want to do
123: something like the following:
124: 1) Make sure the includes and .mk files are up to date.
125: 2) Make sure any program used to build the particular
126: utility is up to date. (yacc, lex, etc...)
127: 3) cd ...path/to/util...
128: make cleandir
129: rm ...all obj directories...
130: make cleandir # yes, again
131: make obj
132: make depend && make
133:
134: Failsafe rebuild of the entire tree:
135: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
136: If you really want to make sure the source tree is clean and
1.2 mrg 137: ready for a build try the following. Note that sourcing /etc/mk.conf
138: (a make(1) Makefile) in this manner is not right, and will not work
139: for anyone who uses any make(1) features in /etc/mk.conf.
1.1 abs 140:
141: ---cut here---
142: #!/bin/sh
143: . /etc/mk.conf
144:
145: if [ -z $BSDSRCDIR ] ; then
146: BSDSRCDIR=/usr/src
147: fi
148: if [ \! -d $BSDSRCDIR ] ; then
149: echo Unable to find sources
150: exit 1
151: fi
152: find $BSDSRCDIR -name \*.o -o -name obj.\* -o -name obj -exec rm \{\} \;
153:
154: if [ -z $BSDOBJDIR ] ; then
155: BSDOBJDIR=/usr/obj
156: fi
157: if [ -d $BSDOBJDIR ] ; then
158: rm -rf $BSDOBJDIR
159: fi
160:
161: cd $BSDSRCDIR && make cleandir

165: Critical utilities:
166: ^^^^^^^^^^^^^^^^^^^
167: gnu/usr.bin/egcs
1.3 itojun 168: usr.bin/compile_et
1.1 abs 169: usr.bin/make
170: usr.bin/yacc
171: usr.bin/lex
1.11 lukem 172: usr.bin/xlint
1.2 mrg 173: usr.sbin/config
1.1 abs 174:
175: Other problems and possibly solutions:
176: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
177: Symptom:Unreasonable compiler errors.
178: Fix: Rebuild gnu/usr.bin/egcs
179:
180: Symptom:Complaints involving a Makefile.
1.17 erh 181: Fix: Rebuild usr.bin/make:
182: cd usr.bin/make && make && make install
183: Or, a failsafe method if that doesn't work:
184: cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
185:
1.1 abs 186: Fix: Make sure .mk files are up to date.
187: cd share/mk && make install
1.2 mrg 188:
189: Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
190: Fix: Rebuild usr.sbin/config
1.1 abs 191:
192: Symptom:
193: Fix: Rebuild usr.bin/yacc
194:
195: Symptom:
196: Fix: Rebuild usr.bin/lex
197:
198: Symptom:
199: Fix: rm /usr/lib/libbfd.a
1.4 itojun 200:
201: Symptom:Obsolete intermediate files are used during compilation
202: Fix: Try the following sequence of commands in the directory in question.
203: make cleandir; rm `make print-objdir`; make cleandir; make obj
204: (If you built the tree without "make obj" in the past, obsolete files
205: may remain. The command tries to clean everything up)

207: Symptom:.../sysinst/run.c:xx: warning: initialization from incompatible pointer type
208: Fix: Rebuild and install usr.bin/menuc

214: Fix: Rebuild and install lib/libc
215:
1.19 cgd 216: Symptom:usr.sbin/config fails to build.
217: Fix: Try building with -DMAKE_BOOTSTRAP added to CFLAGS in Makefile.
