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: ^^^^^^^^^^^^^^^
1.32 ! itojun 10:
! 11: 20010814:
! 12: TOOLDIR must be set in /etc/mk.conf.
! 13: http://mail-index.netbsd.org/current-users/2001/08/14/0002.html
1.31 enami 14:
15: 20010803:
16: grep.info is now built from grep.texi using makeinfo. Since it
17: requires makeinfo v4.0, you need to install new texinfo before
18: building gnu/usr.bin/grep. To install new texinfo, please follow
19: the instruction described in 20010726 entry.
1.30 enami 20:
21: 20010803:
22: (i386 only): i386 kernel now uses new instructions like fxsave which
23: old gas doesn't understand. To build the kernel successfuly, you
24: need to build and install new gas (gnu/usr.bin/gas.new).
1.29 bjh21 25:
26: 20010731:
27: Bootloader update on ELF platforms. DDB in kernels from before
28: this will be unable to read symbol tables provided by newer
29: bootloaders.
1.27 assar 30:
31: 20010726:
32: Texinfo was updated to 4.0. To avoid failures when trying to
1.28 assar 33: build the included texinfo files, do:
34:
35: cd src/gnu/usr.bin/texinfo
36: make MKINFO=no dependall install
1.25 thorpej 37:
38: 20010718:
39:
40: Enabled correct .init/.fini processing in crt0. The way this
41: was done was to change a -I directive to cc(1), which means
42: make(1) will have a stale dependency (it will be checking the
43: timestamp on the wrong "dot_init.h").
44:
45: The symptom you will see is that new programs die with SIGSEGV
46: if you have a stale dependency.
47:
48: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
49: before starting your build.
1.26 thorpej 50:
51: 20010628:
52:
53: A construct was added to uvm_page.h that uncovered a bug
54: in lint(1). If you get a warning/error about a non-portable
55: bitfield, update your lint(1) before proceeding.
1.21 jmc 56:
57: 20010226:
58:
1.22 jmc 59: Added named user/group to system. Need to hand add this in or builds
1.21 jmc 60: will break as mtree aborts early.
61:
62: To work around add by hand:
63:
64: named:*:14:
65:
1.22 jmc 66: to /etc/group and add:
67:
68: named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin
69:
70: to master.passwd (use vipw for instance if doing by hand).
71:
72: Now a make build should progress.
1.18 jmc 73:
74: 20010219:
75: get/setprogname() added. Any hostprog's that may use this will need
1.20 jmc 76: to be bootstrapped manually until the host system is current.
1.18 jmc 77:
78: Known problems: sys/arch/macppc/stand/fixcoff
1.19 cgd 79: usr.sbin/config (adding -DMAKE_BOOTSTRAP to
80: CFLAGS and rebuilding should work)
1.20 jmc 81: usr.sbin/mdsetimage - Build a static copy if
82: building a snapshot before fully bootstrapped.
1.15 christos 83:
84: 20010204:
85: prepare the code to compile with stricter gcc flags. in
86: particular start eliminating redundant declarations. Yacc
87: needs to be installed before make build.
1.10 christos 88:
89: 20010114:
90: introduce .if commands(target) in make(1). You need to
91: bring everything up-to-date first, then without installing
1.23 tron 92: anything make and install in usr.bin/make, then proceed
1.10 christos 93: with make build.
1.9 sommerfe 94:
95: 20010101:
96: bsd.subdir.mk committed 20001230 had a bug which caused
97: afterinstall targets to run too soon; update again.
1.8 sommerfe 98:
99: 20001230:
100: New share/mk files needed to support .WAIT in SUBDIR variables.
101: If you get make errors,
102: (cd share/mk; make install)
103: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 104:
105: 20001019:
1.7 ad 106: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 107: major and minor numbers haven't changed, you should update your /dev
108: directory.
1.1 abs 109:
1.4 itojun 110: 20000929:
111: The following make directives are obsoleted.
112: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
113: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 114: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 115: additional library libcrypto_{idea,rc5}.
116:
1.1 abs 117: 20000623:
118: MKCRYPTO and friends added to share/mk/bsd.own.mk.
119: 'cd share/mk ; make install' needed before make build.
120:
121:
122: Hints for a more successful build:
123: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 124: Build a new kernel first:
125: This makes sure that any new system calls or features
126: expected by the new userland will be present. This
127: helps to avoid critical errors when upgrading.
1.1 abs 128: Use object directories:
129: This helps to keep stale object
130: files from polluting the build if a Makefile "forgets"
131: about one. It also makes it easier to clean up after
132: a build. It's also necessary if you want to use the
133: same source tree for multiple machines.
134: To use object directories:
135: a) cd /usr/src ; make cleandir
1.2 mrg 136: b) Add "OBJMACHINE=yes" to /etc/mk.conf
137: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 138: d) cd /usr/src ; make build
1.2 mrg 139: Note that running "make obj" in a directory will create
140: in obj.$MACHINE directory.
1.1 abs 141: Build to a DESTDIR:
142: This helps to keep old
143: installed files (especially libraries) from interfering
144: with the new build.
145: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 146: variable before running make build. It should be set to
147: the pathname of an initially empty directory.
1.1 abs 148: Problems: you might need to update critical utilities
149: without using DESTDIR since nothing is executed
150: from what is installed in DESTDIR.
151: (See critical utils, below)
152: Build often:
153: This keeps critical utilities current enough to not choke
154: on any other part of the source tree that depends on up to
155: date functionality.
156:
157: What to do if things don't work:
158: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
159: When things don't work there is usually a few things that commonly
160: should be done.
161: 1) make includes
162: This should be done automatically by make build.
163: 2) cd share/mk && make install
164: Again, automatically done by make build.
165:
166: Failsafe rebuild of a small part of the tree:
167: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
168: To make sure you rebuild something correctly you want to do
169: something like the following:
170: 1) Make sure the includes and .mk files are up to date.
171: 2) Make sure any program used to build the particular
172: utility is up to date. (yacc, lex, etc...)
173: 3) cd ...path/to/util...
174: make cleandir
175: rm ...all obj directories...
176: make cleandir # yes, again
177: make obj
178: make depend && make
179:
180: Failsafe rebuild of the entire tree:
181: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
182: If you really want to make sure the source tree is clean and
1.2 mrg 183: ready for a build try the following. Note that sourcing /etc/mk.conf
184: (a make(1) Makefile) in this manner is not right, and will not work
185: for anyone who uses any make(1) features in /etc/mk.conf.
1.1 abs 186:
187: ---cut here---
188: #!/bin/sh
189: . /etc/mk.conf

192: BSDSRCDIR=/usr/src

194: if [ \! -d $BSDSRCDIR ] ; then
195: echo Unable to find sources
196: exit 1
197: fi
198: find $BSDSRCDIR -name \*.o -o -name obj.\* -o -name obj -exec rm \{\} \;

221: Other problems and possibly solutions:
222: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
223: Symptom:Unreasonable compiler errors.
224: Fix: Rebuild gnu/usr.bin/egcs
225:
226: Symptom:Complaints involving a Makefile.
1.17 erh 227: Fix: Rebuild usr.bin/make:
228: cd usr.bin/make && make && make install
229: Or, a failsafe method if that doesn't work:
230: cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
231:
1.1 abs 232: Fix: Make sure .mk files are up to date.

244: Symptom:
245: Fix: rm /usr/lib/libbfd.a
1.4 itojun 246:
247: Symptom:Obsolete intermediate files are used during compilation
248: Fix: Try the following sequence of commands in the directory in question.
249: make cleandir; rm `make print-objdir`; make cleandir; make obj
250: (If you built the tree without "make obj" in the past, obsolete files
251: may remain. The command tries to clean everything up)
