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: ^^^^^^^^^^^^^^^
1.29 ! bjh21 10:
! 11: 20010731:
! 12: Bootloader update on ELF platforms. DDB in kernels from before
! 13: this will be unable to read symbol tables provided by newer
! 14: bootloaders.
1.27 assar 15:
16: 20010726:
17: Texinfo was updated to 4.0. To avoid failures when trying to
1.28 assar 18: build the included texinfo files, do:
19:
20: cd src/gnu/usr.bin/texinfo
21: make MKINFO=no dependall install
1.25 thorpej 22:
23: 20010718:
24:
25: Enabled correct .init/.fini processing in crt0. The way this
26: was done was to change a -I directive to cc(1), which means
27: make(1) will have a stale dependency (it will be checking the
28: timestamp on the wrong "dot_init.h").
29:
30: The symptom you will see is that new programs die with SIGSEGV
31: if you have a stale dependency.
32:
33: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
34: before starting your build.
1.26 thorpej 35:
36: 20010628:
37:
38: A construct was added to uvm_page.h that uncovered a bug
39: in lint(1). If you get a warning/error about a non-portable
40: bitfield, update your lint(1) before proceeding.
1.21 jmc 41:
42: 20010226:
43:
1.22 jmc 44: Added named user/group to system. Need to hand add this in or builds
1.21 jmc 45: will break as mtree aborts early.
46:
47: To work around add by hand:
48:
49: named:*:14:
50:
1.22 jmc 51: to /etc/group and add:
52:
53: named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin
54:
55: to master.passwd (use vipw for instance if doing by hand).
56:
57: Now a make build should progress.
1.18 jmc 58:
59: 20010219:
60: get/setprogname() added. Any hostprog's that may use this will need
1.20 jmc 61: to be bootstrapped manually until the host system is current.
1.18 jmc 62:
63: Known problems: sys/arch/macppc/stand/fixcoff
1.19 cgd 64: usr.sbin/config (adding -DMAKE_BOOTSTRAP to
65: CFLAGS and rebuilding should work)
1.20 jmc 66: usr.sbin/mdsetimage - Build a static copy if
67: building a snapshot before fully bootstrapped.
1.15 christos 68:
69: 20010204:
70: prepare the code to compile with stricter gcc flags. in
71: particular start eliminating redundant declarations. Yacc
72: needs to be installed before make build.
1.10 christos 73:
74: 20010114:
75: introduce .if commands(target) in make(1). You need to
76: bring everything up-to-date first, then without installing
1.23 tron 77: anything make and install in usr.bin/make, then proceed
1.10 christos 78: with make build.
1.9 sommerfe 79:
80: 20010101:
81: bsd.subdir.mk committed 20001230 had a bug which caused
82: afterinstall targets to run too soon; update again.
1.8 sommerfe 83:
84: 20001230:
85: New share/mk files needed to support .WAIT in SUBDIR variables.
86: If you get make errors,
87: (cd share/mk; make install)
88: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 89:
90: 20001019:
1.7 ad 91: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 92: major and minor numbers haven't changed, you should update your /dev
93: directory.
1.1 abs 94:
1.4 itojun 95: 20000929:
96: The following make directives are obsoleted.
97: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
98: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 99: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 100: additional library libcrypto_{idea,rc5}.
101:
1.1 abs 102: 20000623:
103: MKCRYPTO and friends added to share/mk/bsd.own.mk.
104: 'cd share/mk ; make install' needed before make build.
105:
106:
107: Hints for a more successful build:
108: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 109: Build a new kernel first:
110: This makes sure that any new system calls or features
111: expected by the new userland will be present. This
112: helps to avoid critical errors when upgrading.
1.1 abs 113: Use object directories:
114: This helps to keep stale object
115: files from polluting the build if a Makefile "forgets"
116: about one. It also makes it easier to clean up after
117: a build. It's also necessary if you want to use the
118: same source tree for multiple machines.
119: To use object directories:
120: a) cd /usr/src ; make cleandir
1.2 mrg 121: b) Add "OBJMACHINE=yes" to /etc/mk.conf
122: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 123: d) cd /usr/src ; make build
1.2 mrg 124: Note that running "make obj" in a directory will create
125: in obj.$MACHINE directory.
1.1 abs 126: Build to a DESTDIR:
127: This helps to keep old
128: installed files (especially libraries) from interfering
129: with the new build.
130: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 131: variable before running make build. It should be set to
132: the pathname of an initially empty directory.
1.1 abs 133: Problems: you might need to update critical utilities
134: without using DESTDIR since nothing is executed
135: from what is installed in DESTDIR.
136: (See critical utils, below)
137: Build often:
138: This keeps critical utilities current enough to not choke
139: on any other part of the source tree that depends on up to
140: date functionality.
141:
142: What to do if things don't work:
143: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
144: When things don't work there is usually a few things that commonly
145: should be done.
146: 1) make includes
147: This should be done automatically by make build.
148: 2) cd share/mk && make install
149: Again, automatically done by make build.
150:
151: Failsafe rebuild of a small part of the tree:
152: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
153: To make sure you rebuild something correctly you want to do
154: something like the following:
155: 1) Make sure the includes and .mk files are up to date.
156: 2) Make sure any program used to build the particular
157: utility is up to date. (yacc, lex, etc...)
158: 3) cd ...path/to/util...
159: make cleandir
160: rm ...all obj directories...
161: make cleandir # yes, again
162: make obj
163: make depend && make
164:
165: Failsafe rebuild of the entire tree:
166: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
167: If you really want to make sure the source tree is clean and
1.2 mrg 168: ready for a build try the following. Note that sourcing /etc/mk.conf
169: (a make(1) Makefile) in this manner is not right, and will not work
170: for anyone who uses any make(1) features in /etc/mk.conf.
1.1 abs 171:
172: ---cut here---
173: #!/bin/sh
174: . /etc/mk.conf
175:
176: if [ -z $BSDSRCDIR ] ; then
177: BSDSRCDIR=/usr/src
178: fi
179: if [ \! -d $BSDSRCDIR ] ; then
180: echo Unable to find sources
181: exit 1
182: fi
183: find $BSDSRCDIR -name \*.o -o -name obj.\* -o -name obj -exec rm \{\} \;
184:
185: if [ -z $BSDOBJDIR ] ; then
186: BSDOBJDIR=/usr/obj
187: fi
188: if [ -d $BSDOBJDIR ] ; then
189: rm -rf $BSDOBJDIR
190: fi
191:
192: cd $BSDSRCDIR && make cleandir

1.1 abs 205:
206: Other problems and possibly solutions:
207: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
208: Symptom:Unreasonable compiler errors.
209: Fix: Rebuild gnu/usr.bin/egcs
210:
211: Symptom:Complaints involving a Makefile.
1.17 erh 212: Fix: Rebuild usr.bin/make:
213: cd usr.bin/make && make && make install
214: Or, a failsafe method if that doesn't work:
215: cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
216:
1.1 abs 217: Fix: Make sure .mk files are up to date.
218: cd share/mk && make install
1.2 mrg 219:
220: Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
221: Fix: Rebuild usr.sbin/config
1.1 abs 222:
223: Symptom:
224: Fix: Rebuild usr.bin/yacc

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