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.
5:
6: For a more detailed description see Makefile.

8: Recent changes:
9: ^^^^^^^^^^^^^^^
1.40 lukem 10:
11: 20011006:
12: /etc/mtree/NetBSD.dist has been updated to take advantage of
13: absolute path support added to mtree(8). Older mtree(8)s don't
14: understand the format.
15:
16: Solution: update and reinstall usr.sbin/mtree
1.39 jmc 17:
18: 20011004:
19:
20: Crunchgen has been updated to work via reach-over makefiles. Updating
21: is suggested before running a snapshot build
1.36 tv 22:
23: 20010922:
24: The new toolchain is enabled on i386. This new build method
1.38 tron 25: is intended to make all the upgrade issues elsewhere in UPDATING
1.36 tv 26: obsolete (stay tuned...).
27:
1.37 kristerw 28: i386 platform builds must now set TOOLDIR in mk.conf or the
1.36 tv 29: environment in order to build the system. This is a pathname
30: where host build tools will be installed, and must NOT be
31: the same as src/tools.
32:
33: (Optionally, USETOOLS=no can be set in the environment if you
34: wish to avoid using the separate host toolchain for building a
35: subtree. Otherwise, this will default to "yes" automatically.)
1.35 thorpej 36:
37: 20010915:
38: The new "ubcperf" code committed by Chuck Silvers removed
39: a header file, uvm/uvm_vnode.h. There may be stale .depend
40: files that still reference this file.
41:
42: Solution: "make cleandir && make dependall" in affected
43: directories.
1.31 enami 44:
45: 20010803:
46: grep.info is now built from grep.texi using makeinfo. Since it
47: requires makeinfo v4.0, you need to install new texinfo before
48: building gnu/usr.bin/grep. To install new texinfo, please follow
49: the instruction described in 20010726 entry.
1.30 enami 50:
51: 20010803:
1.41 ! wiz 52: (i386 only): i386 kernel now uses new instructions like
! 53: `fxsave' which old gas doesn't understand. To build the
! 54: kernel successfuly, you need to build and install new gas
! 55: (gnu/usr.bin/gas.new), or (temporarily) comment out
! 56: "options I686_CPU" from your kernel configuration until you
! 57: rebuilt your userland (and got a new gas).
1.29 bjh21 58:
59: 20010731:
60: Bootloader update on ELF platforms. DDB in kernels from before
61: this will be unable to read symbol tables provided by newer
62: bootloaders.
1.27 assar 63:
64: 20010726:
65: Texinfo was updated to 4.0. To avoid failures when trying to
1.28 assar 66: build the included texinfo files, do:
67:
68: cd src/gnu/usr.bin/texinfo
69: make MKINFO=no dependall install
1.25 thorpej 70:
71: 20010718:
72:
73: Enabled correct .init/.fini processing in crt0. The way this
74: was done was to change a -I directive to cc(1), which means
75: make(1) will have a stale dependency (it will be checking the
76: timestamp on the wrong "dot_init.h").
77:
78: The symptom you will see is that new programs die with SIGSEGV
79: if you have a stale dependency.
80:
81: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
82: before starting your build.
1.26 thorpej 83:
84: 20010628:
85:
86: A construct was added to uvm_page.h that uncovered a bug
87: in lint(1). If you get a warning/error about a non-portable
88: bitfield, update your lint(1) before proceeding.
1.21 jmc 89:
90: 20010226:
91:
1.22 jmc 92: Added named user/group to system. Need to hand add this in or builds
1.21 jmc 93: will break as mtree aborts early.
94:
95: To work around add by hand:
96:
97: named:*:14:
98:
1.22 jmc 99: to /etc/group and add:
100:
101: named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin
102:
103: to master.passwd (use vipw for instance if doing by hand).
104:
105: Now a make build should progress.
1.18 jmc 106:
107: 20010219:
108: get/setprogname() added. Any hostprog's that may use this will need
1.20 jmc 109: to be bootstrapped manually until the host system is current.
1.18 jmc 110:
111: Known problems: sys/arch/macppc/stand/fixcoff
1.19 cgd 112: usr.sbin/config (adding -DMAKE_BOOTSTRAP to
113: CFLAGS and rebuilding should work)
1.20 jmc 114: usr.sbin/mdsetimage - Build a static copy if
115: building a snapshot before fully bootstrapped.
1.15 christos 116:
117: 20010204:
118: prepare the code to compile with stricter gcc flags. in
119: particular start eliminating redundant declarations. Yacc
120: needs to be installed before make build.
1.10 christos 121:
122: 20010114:
123: introduce .if commands(target) in make(1). You need to
124: bring everything up-to-date first, then without installing
1.23 tron 125: anything make and install in usr.bin/make, then proceed
1.10 christos 126: with make build.
1.9 sommerfe 127:
128: 20010101:
129: bsd.subdir.mk committed 20001230 had a bug which caused
130: afterinstall targets to run too soon; update again.
1.8 sommerfe 131:
132: 20001230:
133: New share/mk files needed to support .WAIT in SUBDIR variables.
134: If you get make errors,
135: (cd share/mk; make install)
136: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 137:
138: 20001019:
1.7 ad 139: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 140: major and minor numbers haven't changed, you should update your /dev
141: directory.
1.1 abs 142:
1.4 itojun 143: 20000929:
144: The following make directives are obsoleted.
145: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
146: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 147: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 148: additional library libcrypto_{idea,rc5}.
149:
1.1 abs 150: 20000623:
151: MKCRYPTO and friends added to share/mk/bsd.own.mk.
152: 'cd share/mk ; make install' needed before make build.
153:
154:
155: Hints for a more successful build:
156: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 157: Build a new kernel first:
158: This makes sure that any new system calls or features
159: expected by the new userland will be present. This
160: helps to avoid critical errors when upgrading.
1.1 abs 161: Use object directories:
162: This helps to keep stale object
163: files from polluting the build if a Makefile "forgets"
164: about one. It also makes it easier to clean up after
165: a build. It's also necessary if you want to use the
166: same source tree for multiple machines.
167: To use object directories:
168: a) cd /usr/src ; make cleandir
1.2 mrg 169: b) Add "OBJMACHINE=yes" to /etc/mk.conf
170: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 171: d) cd /usr/src ; make build
1.2 mrg 172: Note that running "make obj" in a directory will create
173: in obj.$MACHINE directory.
1.1 abs 174: Build to a DESTDIR:
175: This helps to keep old
176: installed files (especially libraries) from interfering
177: with the new build.
178: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 179: variable before running make build. It should be set to
180: the pathname of an initially empty directory.
1.1 abs 181: Problems: you might need to update critical utilities
182: without using DESTDIR since nothing is executed
183: from what is installed in DESTDIR.
184: (See critical utils, below)
185: Build often:
186: This keeps critical utilities current enough to not choke
187: on any other part of the source tree that depends on up to
188: date functionality.
189:
190: What to do if things don't work:
191: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
192: When things don't work there is usually a few things that commonly
193: should be done.
194: 1) make includes
195: This should be done automatically by make build.
196: 2) cd share/mk && make install
197: Again, automatically done by make build.
198:
199: Failsafe rebuild of a small part of the tree:
200: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
201: To make sure you rebuild something correctly you want to do
202: something like the following:
203: 1) Make sure the includes and .mk files are up to date.
204: 2) Make sure any program used to build the particular
205: utility is up to date. (yacc, lex, etc...)
206: 3) cd ...path/to/util...
207: make cleandir
208: rm ...all obj directories...
209: make cleandir # yes, again
210: make obj
211: make depend && make
212:
213: Failsafe rebuild of the entire tree:
214: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
215: If you really want to make sure the source tree is clean and
1.2 mrg 216: ready for a build try the following. Note that sourcing /etc/mk.conf
217: (a make(1) Makefile) in this manner is not right, and will not work
218: for anyone who uses any make(1) features in /etc/mk.conf.
1.1 abs 219:
220: ---cut here---
221: #!/bin/sh
222: . /etc/mk.conf
223:
224: if [ -z $BSDSRCDIR ] ; then
225: BSDSRCDIR=/usr/src
226: fi
227: if [ \! -d $BSDSRCDIR ] ; then
228: echo Unable to find sources
229: exit 1
230: fi
231: find $BSDSRCDIR -name \*.o -o -name obj.\* -o -name obj -exec rm \{\} \;
232:
233: if [ -z $BSDOBJDIR ] ; then
234: BSDOBJDIR=/usr/obj
235: fi
236: if [ -d $BSDOBJDIR ] ; then
237: rm -rf $BSDOBJDIR
238: fi
239:
240: cd $BSDSRCDIR && make cleandir
