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.

1.25 ! thorpej 10:
! 11: 20010718:
! 12:
! 13: Enabled correct .init/.fini processing in crt0. The way this
! 14: was done was to change a -I directive to cc(1), which means
! 15: make(1) will have a stale dependency (it will be checking the
! 16: timestamp on the wrong "dot_init.h").
! 17:
! 18: The symptom you will see is that new programs die with SIGSEGV
! 19: if you have a stale dependency.
! 20:
! 21: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
! 22: before starting your build.
1.21 jmc 23:
24: 20010226:
25:
1.22 jmc 26: Added named user/group to system. Need to hand add this in or builds
1.21 jmc 27: will break as mtree aborts early.
28:
29: To work around add by hand:
30:
31: named:*:14:
32:
1.22 jmc 33: to /etc/group and add:
34:
35: named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin
36:
37: to master.passwd (use vipw for instance if doing by hand).
38:
39: Now a make build should progress.
1.18 jmc 40:
41: 20010219:
42: get/setprogname() added. Any hostprog's that may use this will need
1.20 jmc 43: to be bootstrapped manually until the host system is current.
1.18 jmc 44:
45: Known problems: sys/arch/macppc/stand/fixcoff
1.19 cgd 46: usr.sbin/config (adding -DMAKE_BOOTSTRAP to
47: CFLAGS and rebuilding should work)
1.20 jmc 48: usr.sbin/mdsetimage - Build a static copy if
49: building a snapshot before fully bootstrapped.
1.15 christos 50:
51: 20010204:
52: prepare the code to compile with stricter gcc flags. in
53: particular start eliminating redundant declarations. Yacc
54: needs to be installed before make build.
1.10 christos 55:
56: 20010114:
57: introduce .if commands(target) in make(1). You need to
58: bring everything up-to-date first, then without installing
1.23 tron 59: anything make and install in usr.bin/make, then proceed
1.10 christos 60: with make build.
1.9 sommerfe 61:
62: 20010101:
63: bsd.subdir.mk committed 20001230 had a bug which caused
64: afterinstall targets to run too soon; update again.
1.8 sommerfe 65:
66: 20001230:
67: New share/mk files needed to support .WAIT in SUBDIR variables.
68: If you get make errors,
69: (cd share/mk; make install)
70: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 71:
72: 20001019:
1.7 ad 73: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 74: major and minor numbers haven't changed, you should update your /dev
75: directory.
1.1 abs 76:
1.4 itojun 77: 20000929:
78: The following make directives are obsoleted.
79: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
80: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 81: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 82: additional library libcrypto_{idea,rc5}.
83:
1.1 abs 84: 20000623:
85: MKCRYPTO and friends added to share/mk/bsd.own.mk.
86: 'cd share/mk ; make install' needed before make build.
87:
88:
89: Hints for a more successful build:
90: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 91: Build a new kernel first:
92: This makes sure that any new system calls or features
93: expected by the new userland will be present. This
94: helps to avoid critical errors when upgrading.
1.1 abs 95: Use object directories:
96: This helps to keep stale object
97: files from polluting the build if a Makefile "forgets"
98: about one. It also makes it easier to clean up after
99: a build. It's also necessary if you want to use the
100: same source tree for multiple machines.
101: To use object directories:
102: a) cd /usr/src ; make cleandir
1.2 mrg 103: b) Add "OBJMACHINE=yes" to /etc/mk.conf
104: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 105: d) cd /usr/src ; make build
1.2 mrg 106: Note that running "make obj" in a directory will create
107: in obj.$MACHINE directory.
1.1 abs 108: Build to a DESTDIR:
109: This helps to keep old
110: installed files (especially libraries) from interfering
111: with the new build.
112: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 113: variable before running make build. It should be set to
114: the pathname of an initially empty directory.
1.1 abs 115: Problems: you might need to update critical utilities
116: without using DESTDIR since nothing is executed
117: from what is installed in DESTDIR.
118: (See critical utils, below)
119: Build often:
120: This keeps critical utilities current enough to not choke
121: on any other part of the source tree that depends on up to
122: date functionality.
123:
124: What to do if things don't work:
125: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
126: When things don't work there is usually a few things that commonly
127: should be done.
128: 1) make includes
129: This should be done automatically by make build.
130: 2) cd share/mk && make install
131: Again, automatically done by make build.
132:
133: Failsafe rebuild of a small part of the tree:
134: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
135: To make sure you rebuild something correctly you want to do
136: something like the following:
137: 1) Make sure the includes and .mk files are up to date.
138: 2) Make sure any program used to build the particular
139: utility is up to date. (yacc, lex, etc...)
140: 3) cd ...path/to/util...
141: make cleandir
142: rm ...all obj directories...
143: make cleandir # yes, again
144: make obj
145: make depend && make
146:
147: Failsafe rebuild of the entire tree:
148: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
149: If you really want to make sure the source tree is clean and
1.2 mrg 150: ready for a build try the following. Note that sourcing /etc/mk.conf
151: (a make(1) Makefile) in this manner is not right, and will not work
152: for anyone who uses any make(1) features in /etc/mk.conf.
1.1 abs 153:
154: ---cut here---
155: #!/bin/sh
156: . /etc/mk.conf

159: BSDSRCDIR=/usr/src

161: if [ \! -d $BSDSRCDIR ] ; then
162: echo Unable to find sources
163: exit 1
164: fi
165: find $BSDSRCDIR -name \*.o -o -name obj.\* -o -name obj -exec rm \{\} \;

171: rm -rf $BSDOBJDIR
172: fi

178: Critical utilities:

180: gnu/usr.bin/egcs
1.3 itojun 181: usr.bin/compile_et
1.1 abs 182: usr.bin/make
183: usr.bin/yacc
184: usr.bin/lex
1.11 lukem 185: usr.bin/xlint
1.2 mrg 186: usr.sbin/config
1.1 abs 187:
188: Other problems and possibly solutions:
189: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
190: Symptom:Unreasonable compiler errors.
191: Fix: Rebuild gnu/usr.bin/egcs
192:
193: Symptom:Complaints involving a Makefile.
1.17 erh 194: Fix: Rebuild usr.bin/make:
195: cd usr.bin/make && make && make install
196: Or, a failsafe method if that doesn't work:
197: cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
198:
1.1 abs 199: Fix: Make sure .mk files are up to date.
200: cd share/mk && make install
1.2 mrg 201:
202: Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
203: Fix: Rebuild usr.sbin/config
1.1 abs 204:
205: Symptom:
206: Fix: Rebuild usr.bin/yacc

210:
211: Symptom:
212: Fix: rm /usr/lib/libbfd.a
1.4 itojun 213:
214: Symptom:Obsolete intermediate files are used during compilation
215: Fix: Try the following sequence of commands in the directory in question.
216: make cleandir; rm `make print-objdir`; make cleandir; make obj
217: (If you built the tree without "make obj" in the past, obsolete files
218: may remain. The command tries to clean everything up)
