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.

9: ^^^^^^^^^^^^^^^
1.27 assar 10:
11: 20010726:
12: Texinfo was updated to 4.0. To avoid failures when trying to
1.28 ! assar 13: build the included texinfo files, do:
! 14:
! 15: cd src/gnu/usr.bin/texinfo
! 16: make MKINFO=no dependall install
1.25 thorpej 17:
18: 20010718:
19:
20: Enabled correct .init/.fini processing in crt0. The way this
21: was done was to change a -I directive to cc(1), which means
22: make(1) will have a stale dependency (it will be checking the
23: timestamp on the wrong "dot_init.h").
24:
25: The symptom you will see is that new programs die with SIGSEGV
26: if you have a stale dependency.
27:
28: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
29: before starting your build.
1.26 thorpej 30:
31: 20010628:
32:
33: A construct was added to uvm_page.h that uncovered a bug
34: in lint(1). If you get a warning/error about a non-portable
35: bitfield, update your lint(1) before proceeding.
1.21 jmc 36:
37: 20010226:
38:
1.22 jmc 39: Added named user/group to system. Need to hand add this in or builds
1.21 jmc 40: will break as mtree aborts early.
41:
42: To work around add by hand:
43:
44: named:*:14:
45:
1.22 jmc 46: to /etc/group and add:
47:
48: named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin
49:
50: to master.passwd (use vipw for instance if doing by hand).
51:
52: Now a make build should progress.
1.18 jmc 53:
54: 20010219:
55: get/setprogname() added. Any hostprog's that may use this will need
1.20 jmc 56: to be bootstrapped manually until the host system is current.
1.18 jmc 57:
58: Known problems: sys/arch/macppc/stand/fixcoff
1.19 cgd 59: usr.sbin/config (adding -DMAKE_BOOTSTRAP to
60: CFLAGS and rebuilding should work)
1.20 jmc 61: usr.sbin/mdsetimage - Build a static copy if
62: building a snapshot before fully bootstrapped.
1.15 christos 63:
64: 20010204:
65: prepare the code to compile with stricter gcc flags. in
66: particular start eliminating redundant declarations. Yacc
67: needs to be installed before make build.
1.10 christos 68:
69: 20010114:
70: introduce .if commands(target) in make(1). You need to
71: bring everything up-to-date first, then without installing
1.23 tron 72: anything make and install in usr.bin/make, then proceed
1.10 christos 73: with make build.
1.9 sommerfe 74:
75: 20010101:
76: bsd.subdir.mk committed 20001230 had a bug which caused
77: afterinstall targets to run too soon; update again.
1.8 sommerfe 78:
79: 20001230:
80: New share/mk files needed to support .WAIT in SUBDIR variables.
81: If you get make errors,
82: (cd share/mk; make install)
83: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 84:
85: 20001019:
1.7 ad 86: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 87: major and minor numbers haven't changed, you should update your /dev
88: directory.
1.1 abs 89:
1.4 itojun 90: 20000929:
91: The following make directives are obsoleted.
92: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
93: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 94: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 95: additional library libcrypto_{idea,rc5}.
96:
1.1 abs 97: 20000623:
98: MKCRYPTO and friends added to share/mk/bsd.own.mk.
99: 'cd share/mk ; make install' needed before make build.
100:
101:
102: Hints for a more successful build:
103: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 104: Build a new kernel first:
105: This makes sure that any new system calls or features
106: expected by the new userland will be present. This
107: helps to avoid critical errors when upgrading.
1.1 abs 108: Use object directories:
109: This helps to keep stale object
110: files from polluting the build if a Makefile "forgets"
111: about one. It also makes it easier to clean up after
112: a build. It's also necessary if you want to use the
113: same source tree for multiple machines.
114: To use object directories:
115: a) cd /usr/src ; make cleandir
1.2 mrg 116: b) Add "OBJMACHINE=yes" to /etc/mk.conf
117: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 118: d) cd /usr/src ; make build
1.2 mrg 119: Note that running "make obj" in a directory will create
120: in obj.$MACHINE directory.
1.1 abs 121: Build to a DESTDIR:
122: This helps to keep old
123: installed files (especially libraries) from interfering
124: with the new build.
125: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 126: variable before running make build. It should be set to
127: the pathname of an initially empty directory.
1.1 abs 128: Problems: you might need to update critical utilities
129: without using DESTDIR since nothing is executed
130: from what is installed in DESTDIR.
131: (See critical utils, below)
132: Build often:
133: This keeps critical utilities current enough to not choke
134: on any other part of the source tree that depends on up to
135: date functionality.
136:
137: What to do if things don't work:
138: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
139: When things don't work there is usually a few things that commonly
140: should be done.
141: 1) make includes
142: This should be done automatically by make build.
143: 2) cd share/mk && make install
144: Again, automatically done by make build.
145:
146: Failsafe rebuild of a small part of the tree:
147: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
148: To make sure you rebuild something correctly you want to do
149: something like the following:
150: 1) Make sure the includes and .mk files are up to date.
151: 2) Make sure any program used to build the particular
152: utility is up to date. (yacc, lex, etc...)
153: 3) cd ...path/to/util...
154: make cleandir
155: rm ...all obj directories...
156: make cleandir # yes, again
157: make obj
158: make depend && make
159:
160: Failsafe rebuild of the entire tree:
161: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
162: If you really want to make sure the source tree is clean and
1.2 mrg 163: ready for a build try the following. Note that sourcing /etc/mk.conf
164: (a make(1) Makefile) in this manner is not right, and will not work
165: for anyone who uses any make(1) features in /etc/mk.conf.
1.1 abs 166:
167: ---cut here---
168: #!/bin/sh
169: . /etc/mk.conf

172: BSDSRCDIR=/usr/src
173: fi
174: if [ \! -d $BSDSRCDIR ] ; then
175: echo Unable to find sources
176: exit 1
177: fi
178: find $BSDSRCDIR -name \*.o -o -name obj.\* -o -name obj -exec rm \{\} \;

181: BSDOBJDIR=/usr/obj

183: if [ -d $BSDOBJDIR ] ; then
184: rm -rf $BSDOBJDIR
185: fi

1.1 abs 200:
201: Other problems and possibly solutions:
202: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
203: Symptom:Unreasonable compiler errors.
204: Fix: Rebuild gnu/usr.bin/egcs
205:
206: Symptom:Complaints involving a Makefile.
1.17 erh 207: Fix: Rebuild usr.bin/make:
208: cd usr.bin/make && make && make install
209: Or, a failsafe method if that doesn't work:
210: cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
211:
1.1 abs 212: Fix: Make sure .mk files are up to date.
213: cd share/mk && make install
1.2 mrg 214:
215: Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
216: Fix: Rebuild usr.sbin/config
1.1 abs 217:
218: Symptom:
219: Fix: Rebuild usr.bin/yacc

224: Symptom:
225: Fix: rm /usr/lib/libbfd.a
1.4 itojun 226:
227: Symptom:Obsolete intermediate files are used during compilation
228: Fix: Try the following sequence of commands in the directory in question.
229: make cleandir; rm `make print-objdir`; make cleandir; make obj
230: (If you built the tree without "make obj" in the past, obsolete files
231: may remain. The command tries to clean everything up)
