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
1.20 ! jmc 13: to be bootstrapped manually until the host system is current.
1.18 jmc 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)
1.20 ! jmc 18: usr.sbin/mdsetimage - Build a static copy if
! 19: building a snapshot before fully bootstrapped.
1.15 christos 20:
21: 20010204:
22: prepare the code to compile with stricter gcc flags. in
23: particular start eliminating redundant declarations. Yacc
24: needs to be installed before make build.
1.10 christos 25:
26: 20010114:
27: introduce .if commands(target) in make(1). You need to
28: bring everything up-to-date first, then without installing
29: anything make and install in /usr/bin/make, then proceed
30: with make build.
1.9 sommerfe 31:
32: 20010101:
33: bsd.subdir.mk committed 20001230 had a bug which caused
34: afterinstall targets to run too soon; update again.
1.8 sommerfe 35:
36: 20001230:
37: New share/mk files needed to support .WAIT in SUBDIR variables.
38: If you get make errors,
39: (cd share/mk; make install)
40: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 41:
42: 20001019:
1.7 ad 43: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 44: major and minor numbers haven't changed, you should update your /dev
45: directory.
1.1 abs 46:
1.4 itojun 47: 20000929:
48: The following make directives are obsoleted.
49: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
50: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 51: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 52: additional library libcrypto_{idea,rc5}.
53:
1.1 abs 54: 20000623:
55: MKCRYPTO and friends added to share/mk/bsd.own.mk.
56: 'cd share/mk ; make install' needed before make build.
57:

59: Hints for a more successful build:
60: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 61: Build a new kernel first:
62: This makes sure that any new system calls or features
63: expected by the new userland will be present. This
64: helps to avoid critical errors when upgrading.
1.1 abs 65: Use object directories:
66: This helps to keep stale object
67: files from polluting the build if a Makefile "forgets"
68: about one. It also makes it easier to clean up after
69: a build. It's also necessary if you want to use the
70: same source tree for multiple machines.
71: To use object directories:
72: a) cd /usr/src ; make cleandir
1.2 mrg 73: b) Add "OBJMACHINE=yes" to /etc/mk.conf
74: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 75: d) cd /usr/src ; make build
1.2 mrg 76: Note that running "make obj" in a directory will create
77: in obj.$MACHINE directory.
1.1 abs 78: Build to a DESTDIR:
79: This helps to keep old
80: installed files (especially libraries) from interfering
81: with the new build.
82: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 83: variable before running make build. It should be set to
84: the pathname of an initially empty directory.
1.1 abs 85: Problems: you might need to update critical utilities
86: without using DESTDIR since nothing is executed
87: from what is installed in DESTDIR.
88: (See critical utils, below)
89: Build often:
90: This keeps critical utilities current enough to not choke
91: on any other part of the source tree that depends on up to
92: date functionality.
93:
94: What to do if things don't work:
95: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
96: When things don't work there is usually a few things that commonly
97: should be done.
98: 1) make includes
99: This should be done automatically by make build.
100: 2) cd share/mk && make install
101: Again, automatically done by make build.
102:
103: Failsafe rebuild of a small part of the tree:
104: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
105: To make sure you rebuild something correctly you want to do
106: something like the following:
107: 1) Make sure the includes and .mk files are up to date.
108: 2) Make sure any program used to build the particular
109: utility is up to date. (yacc, lex, etc...)
110: 3) cd ...path/to/util...
111: make cleandir
112: rm ...all obj directories...
113: make cleandir # yes, again
114: make obj
115: make depend && make
116:
117: Failsafe rebuild of the entire tree:
118: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
119: If you really want to make sure the source tree is clean and
1.2 mrg 120: ready for a build try the following. Note that sourcing /etc/mk.conf
121: (a make(1) Makefile) in this manner is not right, and will not work
122: for anyone who uses any make(1) features in /etc/mk.conf.
1.1 abs 123:
124: ---cut here---
125: #!/bin/sh
126: . /etc/mk.conf
127:
128: if [ -z $BSDSRCDIR ] ; then
129: BSDSRCDIR=/usr/src
130: fi
131: if [ \! -d $BSDSRCDIR ] ; then
132: echo Unable to find sources
133: exit 1
134: fi
135: find $BSDSRCDIR -name \*.o -o -name obj.\* -o -name obj -exec rm \{\} \;
136:
137: if [ -z $BSDOBJDIR ] ; then
138: BSDOBJDIR=/usr/obj
139: fi
140: if [ -d $BSDOBJDIR ] ; then
141: rm -rf $BSDOBJDIR
142: fi
143:
144: cd $BSDSRCDIR && make cleandir
145:
146: ---cut here---

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

191: Fix: Rebuild and install usr.bin/menuc
1.12 itojun 192:

196: Symptom:undefined reference to `__assert13'
197: Fix: Rebuild and install lib/libc
198:
1.19 cgd 199: Symptom:usr.sbin/config fails to build.
200: Fix: Try building with -DMAKE_BOOTSTRAP added to CFLAGS in Makefile.
