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.

6: For a more detailed description see Makefile.

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

170: BSDSRCDIR=/usr/src

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

178: if [ -z $BSDOBJDIR ] ; then
179: BSDOBJDIR=/usr/obj

181: if [ -d $BSDOBJDIR ] ; then
182: rm -rf $BSDOBJDIR
183: fi

1.1 abs 193: usr.bin/make
194: usr.bin/yacc

1.11 lukem 196: usr.bin/xlint
1.2 mrg 197: usr.sbin/config
1.1 abs 198:
199: Other problems and possibly solutions:
200: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
201: Symptom:Unreasonable compiler errors.
202: Fix: Rebuild gnu/usr.bin/egcs
203:
204: Symptom:Complaints involving a Makefile.
1.17 erh 205: Fix: Rebuild usr.bin/make:
206: cd usr.bin/make && make && make install
207: Or, a failsafe method if that doesn't work:
208: cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
209:
1.1 abs 210: Fix: Make sure .mk files are up to date.
211: cd share/mk && make install
1.2 mrg 212:
213: Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
214: Fix: Rebuild usr.sbin/config
1.1 abs 215:
216: Symptom:
217: Fix: Rebuild usr.bin/yacc

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