4: process and a reference on what to do if something doesn't work.

9: ^^^^^^^^^^^^^^^
1.21 ! jmc 10:
! 11: 20010226:
! 12:
! 13: Added named group to /etc/group. Need to hand add this in or builds
! 14: will break as mtree aborts early.
! 15:
! 16: To work around add by hand:
! 17:
! 18: named:*:14:
! 19:
! 20: to /etc/group before make build.
1.18 jmc 21:
22: 20010219:
23: get/setprogname() added. Any hostprog's that may use this will need
1.20 jmc 24: to be bootstrapped manually until the host system is current.
1.18 jmc 25:
26: Known problems: sys/arch/macppc/stand/fixcoff
1.19 cgd 27: usr.sbin/config (adding -DMAKE_BOOTSTRAP to
28: CFLAGS and rebuilding should work)
1.20 jmc 29: usr.sbin/mdsetimage - Build a static copy if
30: building a snapshot before fully bootstrapped.
1.15 christos 31:
32: 20010204:
33: prepare the code to compile with stricter gcc flags. in
34: particular start eliminating redundant declarations. Yacc
35: needs to be installed before make build.
1.10 christos 36:
37: 20010114:
38: introduce .if commands(target) in make(1). You need to
39: bring everything up-to-date first, then without installing
40: anything make and install in /usr/bin/make, then proceed
41: with make build.
1.9 sommerfe 42:
43: 20010101:
44: bsd.subdir.mk committed 20001230 had a bug which caused
45: afterinstall targets to run too soon; update again.
1.8 sommerfe 46:
47: 20001230:
48: New share/mk files needed to support .WAIT in SUBDIR variables.
49: If you get make errors,
50: (cd share/mk; make install)
51: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 52:
53: 20001019:
1.7 ad 54: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 55: major and minor numbers haven't changed, you should update your /dev
56: directory.
1.1 abs 57:
1.4 itojun 58: 20000929:
59: The following make directives are obsoleted.
60: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
61: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 62: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 63: additional library libcrypto_{idea,rc5}.
64:
1.1 abs 65: 20000623:
66: MKCRYPTO and friends added to share/mk/bsd.own.mk.
67: 'cd share/mk ; make install' needed before make build.
68:

70: Hints for a more successful build:
71: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 72: Build a new kernel first:
73: This makes sure that any new system calls or features
74: expected by the new userland will be present. This
75: helps to avoid critical errors when upgrading.
1.1 abs 76: Use object directories:
77: This helps to keep stale object
78: files from polluting the build if a Makefile "forgets"
79: about one. It also makes it easier to clean up after
80: a build. It's also necessary if you want to use the
81: same source tree for multiple machines.
82: To use object directories:
83: a) cd /usr/src ; make cleandir
1.2 mrg 84: b) Add "OBJMACHINE=yes" to /etc/mk.conf
85: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 86: d) cd /usr/src ; make build
1.2 mrg 87: Note that running "make obj" in a directory will create
88: in obj.$MACHINE directory.
1.1 abs 89: Build to a DESTDIR:
90: This helps to keep old
91: installed files (especially libraries) from interfering
92: with the new build.
93: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 94: variable before running make build. It should be set to
95: the pathname of an initially empty directory.
1.1 abs 96: Problems: you might need to update critical utilities
97: without using DESTDIR since nothing is executed
98: from what is installed in DESTDIR.
99: (See critical utils, below)
100: Build often:
101: This keeps critical utilities current enough to not choke
102: on any other part of the source tree that depends on up to
103: date functionality.
104:
105: What to do if things don't work:
106: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
107: When things don't work there is usually a few things that commonly
108: should be done.
109: 1) make includes
110: This should be done automatically by make build.
111: 2) cd share/mk && make install
112: Again, automatically done by make build.
113:
114: Failsafe rebuild of a small part of the tree:
115: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
116: To make sure you rebuild something correctly you want to do
117: something like the following:
118: 1) Make sure the includes and .mk files are up to date.
119: 2) Make sure any program used to build the particular
120: utility is up to date. (yacc, lex, etc...)
121: 3) cd ...path/to/util...
122: make cleandir
123: rm ...all obj directories...
124: make cleandir # yes, again
125: make obj
126: make depend && make
127:
128: Failsafe rebuild of the entire tree:
129: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
130: If you really want to make sure the source tree is clean and
1.2 mrg 131: ready for a build try the following. Note that sourcing /etc/mk.conf
132: (a make(1) Makefile) in this manner is not right, and will not work
133: for anyone who uses any make(1) features in /etc/mk.conf.
1.1 abs 134:
135: ---cut here---
136: #!/bin/sh
137: . /etc/mk.conf
138:
139: if [ -z $BSDSRCDIR ] ; then
140: BSDSRCDIR=/usr/src
141: fi
142: if [ \! -d $BSDSRCDIR ] ; then
143: echo Unable to find sources
144: exit 1
145: fi
146: find $BSDSRCDIR -name \*.o -o -name obj.\* -o -name obj -exec rm \{\} \;
147:
148: if [ -z $BSDOBJDIR ] ; then
149: BSDOBJDIR=/usr/obj
150: fi
151: if [ -d $BSDOBJDIR ] ; then
152: rm -rf $BSDOBJDIR
153: fi
154:
155: cd $BSDSRCDIR && make cleandir

159: Critical utilities:
160: ^^^^^^^^^^^^^^^^^^^
161: gnu/usr.bin/egcs
1.3 itojun 162: usr.bin/compile_et
1.1 abs 163: usr.bin/make
164: usr.bin/yacc
165: usr.bin/lex
1.11 lukem 166: usr.bin/xlint
1.2 mrg 167: usr.sbin/config
1.1 abs 168:
169: Other problems and possibly solutions:
170: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
171: Symptom:Unreasonable compiler errors.
172: Fix: Rebuild gnu/usr.bin/egcs
173:
174: Symptom:Complaints involving a Makefile.
1.17 erh 175: Fix: Rebuild usr.bin/make:
176: cd usr.bin/make && make && make install
177: Or, a failsafe method if that doesn't work:
178: cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
179:
1.1 abs 180: Fix: Make sure .mk files are up to date.
181: cd share/mk && make install
1.2 mrg 182:
183: Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
184: Fix: Rebuild usr.sbin/config
1.1 abs 185:
186: Symptom:
187: Fix: Rebuild usr.bin/yacc
188:
189: Symptom:
190: Fix: Rebuild usr.bin/lex
191:
192: Symptom:
193: Fix: rm /usr/lib/libbfd.a
1.4 itojun 194:
195: Symptom:Obsolete intermediate files are used during compilation
196: Fix: Try the following sequence of commands in the directory in question.
197: make cleandir; rm `make print-objdir`; make cleandir; make obj
198: (If you built the tree without "make obj" in the past, obsolete files
199: may remain. The command tries to clean everything up)

201: Symptom:.../sysinst/run.c:xx: warning: initialization from incompatible pointer type
202: Fix: Rebuild and install usr.bin/menuc
1.12 itojun 203:

208: Fix: Rebuild and install lib/libc
209:
1.19 cgd 210: Symptom:usr.sbin/config fails to build.
211: Fix: Try building with -DMAKE_BOOTSTRAP added to CFLAGS in Makefile.
