1.43 ! mason 1: $NetBSD: UPDATING,v 1.42 2001/10/29 01:46:25 perry Exp $
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.
7:
1.42 perry 8: Note that users of the new toolchain in many instances will not
9: experience the problems listed below because their host tools are
10: automatically generated for them.
11:
1.1 abs 12: Recent changes:
13: ^^^^^^^^^^^^^^^
1.43 ! mason 14:
! 15: 20011028:
! 16: /usr/src/build.sh exists as of 2001.10.19. From the cvs log:
! 17:
! 18: "Script to automate bootstrapping a build on any host platform.
! 19: Creates a bmake (rebuilds, if necessary) and invokes that to
! 20: start the build."
! 21:
! 22: This should, incidentally, allow 1.5.x hosts to build -current
! 23: using the new toolchain, on USE_NEW_TOOLCHAIN-enabled platforms.
1.42 perry 24:
25: 20011028:
26: src/etc/Makefile now needs install to be able to handle
27: symlinks that point to nowhere. A bug in install that
28: prevented this was corrected.
29:
30: Solution: update and reinstall usr.bin/xinstall
31: Better Solution: Use the new toolchain and it will just work
32: for you.
1.40 lukem 33:
34: 20011006:
35: /etc/mtree/NetBSD.dist has been updated to take advantage of
36: absolute path support added to mtree(8). Older mtree(8)s don't
37: understand the format.
38:
39: Solution: update and reinstall usr.sbin/mtree
1.39 jmc 40:
41: 20011004:
42:
43: Crunchgen has been updated to work via reach-over makefiles. Updating
44: is suggested before running a snapshot build
1.36 tv 45:
46: 20010922:
47: The new toolchain is enabled on i386. This new build method
1.38 tron 48: is intended to make all the upgrade issues elsewhere in UPDATING
1.36 tv 49: obsolete (stay tuned...).
50:
1.37 kristerw 51: i386 platform builds must now set TOOLDIR in mk.conf or the
1.36 tv 52: environment in order to build the system. This is a pathname
53: where host build tools will be installed, and must NOT be
54: the same as src/tools.
55:
56: (Optionally, USETOOLS=no can be set in the environment if you
57: wish to avoid using the separate host toolchain for building a
58: subtree. Otherwise, this will default to "yes" automatically.)
1.35 thorpej 59:
60: 20010915:
61: The new "ubcperf" code committed by Chuck Silvers removed
62: a header file, uvm/uvm_vnode.h. There may be stale .depend
63: files that still reference this file.
64:
65: Solution: "make cleandir && make dependall" in affected
66: directories.
1.31 enami 67:
68: 20010803:
69: grep.info is now built from grep.texi using makeinfo. Since it
70: requires makeinfo v4.0, you need to install new texinfo before
71: building gnu/usr.bin/grep. To install new texinfo, please follow
72: the instruction described in 20010726 entry.
1.30 enami 73:
74: 20010803:
1.41 wiz 75: (i386 only): i386 kernel now uses new instructions like
76: `fxsave' which old gas doesn't understand. To build the
77: kernel successfuly, you need to build and install new gas
78: (gnu/usr.bin/gas.new), or (temporarily) comment out
79: "options I686_CPU" from your kernel configuration until you
80: rebuilt your userland (and got a new gas).
1.29 bjh21 81:
82: 20010731:
83: Bootloader update on ELF platforms. DDB in kernels from before
84: this will be unable to read symbol tables provided by newer
85: bootloaders.
1.27 assar 86:
87: 20010726:
88: Texinfo was updated to 4.0. To avoid failures when trying to
1.28 assar 89: build the included texinfo files, do:
90:
91: cd src/gnu/usr.bin/texinfo
92: make MKINFO=no dependall install
1.25 thorpej 93:
94: 20010718:
95:
96: Enabled correct .init/.fini processing in crt0. The way this
97: was done was to change a -I directive to cc(1), which means
98: make(1) will have a stale dependency (it will be checking the
99: timestamp on the wrong "dot_init.h").
100:
101: The symptom you will see is that new programs die with SIGSEGV
102: if you have a stale dependency.
103:
104: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
105: before starting your build.
1.26 thorpej 106:
107: 20010628:
108:
109: A construct was added to uvm_page.h that uncovered a bug
110: in lint(1). If you get a warning/error about a non-portable
111: bitfield, update your lint(1) before proceeding.
1.21 jmc 112:
113: 20010226:
114:
1.22 jmc 115: Added named user/group to system. Need to hand add this in or builds
1.21 jmc 116: will break as mtree aborts early.
117:
118: To work around add by hand:
119:
120: named:*:14:
121:
1.22 jmc 122: to /etc/group and add:
123:
124: named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin
125:
126: to master.passwd (use vipw for instance if doing by hand).
127:
128: Now a make build should progress.
1.18 jmc 129:
130: 20010219:
131: get/setprogname() added. Any hostprog's that may use this will need
1.20 jmc 132: to be bootstrapped manually until the host system is current.
1.18 jmc 133:
134: Known problems: sys/arch/macppc/stand/fixcoff
1.19 cgd 135: usr.sbin/config (adding -DMAKE_BOOTSTRAP to
136: CFLAGS and rebuilding should work)
1.20 jmc 137: usr.sbin/mdsetimage - Build a static copy if
138: building a snapshot before fully bootstrapped.
1.15 christos 139:
140: 20010204:
141: prepare the code to compile with stricter gcc flags. in
142: particular start eliminating redundant declarations. Yacc
143: needs to be installed before make build.
1.10 christos 144:
145: 20010114:
146: introduce .if commands(target) in make(1). You need to
147: bring everything up-to-date first, then without installing
1.23 tron 148: anything make and install in usr.bin/make, then proceed
1.10 christos 149: with make build.
1.9 sommerfe 150:
151: 20010101:
152: bsd.subdir.mk committed 20001230 had a bug which caused
153: afterinstall targets to run too soon; update again.
1.8 sommerfe 154:
155: 20001230:
156: New share/mk files needed to support .WAIT in SUBDIR variables.
157: If you get make errors,
158: (cd share/mk; make install)
159: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 160:
161: 20001019:
1.7 ad 162: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 163: major and minor numbers haven't changed, you should update your /dev
164: directory.
1.1 abs 165:
1.4 itojun 166: 20000929:
167: The following make directives are obsoleted.
168: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
169: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 170: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 171: additional library libcrypto_{idea,rc5}.
172:
1.1 abs 173: 20000623:
174: MKCRYPTO and friends added to share/mk/bsd.own.mk.
175: 'cd share/mk ; make install' needed before make build.
176:
177:
178: Hints for a more successful build:
179: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 180: Build a new kernel first:
181: This makes sure that any new system calls or features
182: expected by the new userland will be present. This
183: helps to avoid critical errors when upgrading.
1.1 abs 184: Use object directories:
185: This helps to keep stale object
186: files from polluting the build if a Makefile "forgets"
187: about one. It also makes it easier to clean up after
188: a build. It's also necessary if you want to use the
189: same source tree for multiple machines.
190: To use object directories:
191: a) cd /usr/src ; make cleandir
1.2 mrg 192: b) Add "OBJMACHINE=yes" to /etc/mk.conf
193: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 194: d) cd /usr/src ; make build
1.2 mrg 195: Note that running "make obj" in a directory will create
196: in obj.$MACHINE directory.
1.1 abs 197: Build to a DESTDIR:
198: This helps to keep old
199: installed files (especially libraries) from interfering
200: with the new build.
201: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 202: variable before running make build. It should be set to
203: the pathname of an initially empty directory.
1.1 abs 204: Problems: you might need to update critical utilities
205: without using DESTDIR since nothing is executed
206: from what is installed in DESTDIR.
207: (See critical utils, below)
208: Build often:
209: This keeps critical utilities current enough to not choke
210: on any other part of the source tree that depends on up to
211: date functionality.
212:
213: What to do if things don't work:
214: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
215: When things don't work there is usually a few things that commonly
216: should be done.
217: 1) make includes
218: This should be done automatically by make build.
219: 2) cd share/mk && make install
220: Again, automatically done by make build.
221:
222: Failsafe rebuild of a small part of the tree:
223: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
224: To make sure you rebuild something correctly you want to do
225: something like the following:
226: 1) Make sure the includes and .mk files are up to date.
227: 2) Make sure any program used to build the particular
228: utility is up to date. (yacc, lex, etc...)
229: 3) cd ...path/to/util...
230: make cleandir
231: rm ...all obj directories...
232: make cleandir # yes, again
233: make obj
234: make depend && make
235:
236: Failsafe rebuild of the entire tree:
237: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
238: If you really want to make sure the source tree is clean and
1.2 mrg 239: ready for a build try the following. Note that sourcing /etc/mk.conf
240: (a make(1) Makefile) in this manner is not right, and will not work
241: for anyone who uses any make(1) features in /etc/mk.conf.
1.1 abs 242:

244: #!/bin/sh
