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: ^^^^^^^^^^^^^^^
1.47 jmc 10: 20011201:
11: In order for a sparc64 build to work you must have a working awk. If
12: you've built and installed a system with the new toolchain up to this
13: point you do not have a working awk as it's abililty to do floating
14: point is broken.
15:
16: To build:
17:
18: remake and install gnu/lib/libgcc
19: remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links
1.48 ! jmc 20: against the new libgcc.a)
1.47 jmc 21:
1.46 thorpej 22: 20011128:
23: Kernel config information was changed to use defflag in
24: the various "files" files. Bug fixes to config(8) are
25: required in order for this to work properly. Make sure
26: to build and install in usr.sbin/config before attempting
27: to build a new kernel.
28:
1.45 yamt 29: 20011030:
30: libc/locale/wcstod.c now needs new lint(1). Update lint(1)
31: before building libc.
1.43 mason 32:
1.44 tv 33: 20011029:
34: The new document BUILDING.mdoc (view with nroff | more, or
35: see pre-generated .txt and .html versions) describes the build
36: procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
37: build process, are intended in the long run to replace this
38: manual update log.
39:
40: Users building a USE_NEW_TOOLCHAIN system should read the
41: BUILDING document for caveats. Generally, BUILDING supersedes
42: UPDATING for these systems, as tool updating is taken care of
43: by the new build system.
1.42 perry 44:
45: 20011028:
46: src/etc/Makefile now needs install to be able to handle
47: symlinks that point to nowhere. A bug in install that
48: prevented this was corrected.
49:
50: Solution: update and reinstall usr.bin/xinstall
51: Better Solution: Use the new toolchain and it will just work
52: for you.
1.40 lukem 53:
54: 20011006:
55: /etc/mtree/NetBSD.dist has been updated to take advantage of
56: absolute path support added to mtree(8). Older mtree(8)s don't
57: understand the format.
58:
59: Solution: update and reinstall usr.sbin/mtree
1.39 jmc 60:
61: 20011004:
62: Crunchgen has been updated to work via reach-over makefiles. Updating
63: is suggested before running a snapshot build
1.36 tv 64:
1.35 thorpej 65: 20010915:
66: The new "ubcperf" code committed by Chuck Silvers removed
67: a header file, uvm/uvm_vnode.h. There may be stale .depend
68: files that still reference this file.
69:
70: Solution: "make cleandir && make dependall" in affected
71: directories.
1.31 enami 72:
73: 20010803:
74: grep.info is now built from grep.texi using makeinfo. Since it
75: requires makeinfo v4.0, you need to install new texinfo before
76: building gnu/usr.bin/grep. To install new texinfo, please follow
77: the instruction described in 20010726 entry.
1.30 enami 78:
79: 20010803:
1.41 wiz 80: (i386 only): i386 kernel now uses new instructions like
81: `fxsave' which old gas doesn't understand. To build the
82: kernel successfuly, you need to build and install new gas
83: (gnu/usr.bin/gas.new), or (temporarily) comment out
84: "options I686_CPU" from your kernel configuration until you
85: rebuilt your userland (and got a new gas).
1.29 bjh21 86:
87: 20010731:
88: Bootloader update on ELF platforms. DDB in kernels from before
89: this will be unable to read symbol tables provided by newer
90: bootloaders.
1.27 assar 91:
92: 20010726:
93: Texinfo was updated to 4.0. To avoid failures when trying to
1.28 assar 94: build the included texinfo files, do:
95:
96: cd src/gnu/usr.bin/texinfo
97: make MKINFO=no dependall install
1.25 thorpej 98:
99: 20010718:
100: Enabled correct .init/.fini processing in crt0. The way this
101: was done was to change a -I directive to cc(1), which means
102: make(1) will have a stale dependency (it will be checking the
103: timestamp on the wrong "dot_init.h").
104:
105: The symptom you will see is that new programs die with SIGSEGV
106: if you have a stale dependency.
107:
108: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
109: before starting your build.
1.26 thorpej 110:
111: 20010628:
112: A construct was added to uvm_page.h that uncovered a bug
113: in lint(1). If you get a warning/error about a non-portable
114: bitfield, update your lint(1) before proceeding.
1.21 jmc 115:
116: 20010226:
1.22 jmc 117: Added named user/group to system. Need to hand add this in or builds
1.21 jmc 118: will break as mtree aborts early.
119:
120: To work around add by hand:
121:
122: named:*:14:
123:
1.22 jmc 124: to /etc/group and add:
125:
126: named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin
127:
128: to master.passwd (use vipw for instance if doing by hand).
129:
130: Now a make build should progress.
1.18 jmc 131:
132: 20010219:
133: get/setprogname() added. Any hostprog's that may use this will need
1.20 jmc 134: to be bootstrapped manually until the host system is current.
1.18 jmc 135:
136: Known problems: sys/arch/macppc/stand/fixcoff
1.19 cgd 137: usr.sbin/config (adding -DMAKE_BOOTSTRAP to
138: CFLAGS and rebuilding should work)
1.20 jmc 139: usr.sbin/mdsetimage - Build a static copy if
140: building a snapshot before fully bootstrapped.
1.15 christos 141:
142: 20010204:
143: prepare the code to compile with stricter gcc flags. in
144: particular start eliminating redundant declarations. Yacc
145: needs to be installed before make build.
1.10 christos 146:
147: 20010114:
148: introduce .if commands(target) in make(1). You need to
149: bring everything up-to-date first, then without installing
1.23 tron 150: anything make and install in usr.bin/make, then proceed
1.10 christos 151: with make build.
1.9 sommerfe 152:
153: 20010101:
154: bsd.subdir.mk committed 20001230 had a bug which caused
155: afterinstall targets to run too soon; update again.
1.8 sommerfe 156:
157: 20001230:
158: New share/mk files needed to support .WAIT in SUBDIR variables.
159: If you get make errors,
160: (cd share/mk; make install)
161: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 162:
163: 20001019:
1.7 ad 164: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 165: major and minor numbers haven't changed, you should update your /dev
166: directory.
1.1 abs 167:
1.4 itojun 168: 20000929:
169: The following make directives are obsoleted.
170: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
171: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 172: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 173: additional library libcrypto_{idea,rc5}.
1.1 abs 174:
175:
176: Hints for a more successful build:
177: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 178: Build a new kernel first:
179: This makes sure that any new system calls or features
180: expected by the new userland will be present. This
181: helps to avoid critical errors when upgrading.
1.1 abs 182: Use object directories:
183: This helps to keep stale object
184: files from polluting the build if a Makefile "forgets"
185: about one. It also makes it easier to clean up after
186: a build. It's also necessary if you want to use the
187: same source tree for multiple machines.
188: To use object directories:
189: a) cd /usr/src ; make cleandir
1.2 mrg 190: b) Add "OBJMACHINE=yes" to /etc/mk.conf
191: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 192: d) cd /usr/src ; make build
1.2 mrg 193: Note that running "make obj" in a directory will create
194: in obj.$MACHINE directory.
1.1 abs 195: Build to a DESTDIR:
196: This helps to keep old
197: installed files (especially libraries) from interfering
198: with the new build.
199: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 200: variable before running make build. It should be set to
201: the pathname of an initially empty directory.
1.1 abs 202: Problems: you might need to update critical utilities
203: without using DESTDIR since nothing is executed
204: from what is installed in DESTDIR.
205: (See critical utils, below)
206: Build often:
207: This keeps critical utilities current enough to not choke
208: on any other part of the source tree that depends on up to
209: date functionality.
210:
211: What to do if things don't work:
212: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
213: When things don't work there is usually a few things that commonly
214: should be done.
215: 1) make includes
216: This should be done automatically by make build.
217: 2) cd share/mk && make install
218: Again, automatically done by make build.
219:
220: Failsafe rebuild of a small part of the tree:
221: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
222: To make sure you rebuild something correctly you want to do
223: something like the following:
224: 1) Make sure the includes and .mk files are up to date.
225: 2) Make sure any program used to build the particular
226: utility is up to date. (yacc, lex, etc...)
227: 3) cd ...path/to/util...
228: make cleandir
229: rm ...all obj directories...
230: make cleandir # yes, again
231: make obj
232: make depend && make
233:
234: Failsafe rebuild of the entire tree:
235: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
236: If you really want to make sure the source tree is clean and
1.2 mrg 237: ready for a build try the following. Note that sourcing /etc/mk.conf
238: (a make(1) Makefile) in this manner is not right, and will not work
239: for anyone who uses any make(1) features in /etc/mk.conf.
1.1 abs 240:

242: #!/bin/sh

249: echo Unable to find sources
