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

220: #!/bin/sh

227: echo Unable to find sources

257:
258: Symptom:Complaints involving a Makefile.
1.17 erh 259: Fix: Rebuild usr.bin/make:

262: cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
263:
1.1 abs 264: Fix: Make sure .mk files are up to date.

1.4 itojun 278:
279: Symptom:Obsolete intermediate files are used during compilation
280: Fix: Try the following sequence of commands in the directory in question.
281: make cleandir; rm `make print-objdir`; make cleandir; make obj
282: (If you built the tree without "make obj" in the past, obsolete files
283: may remain. The command tries to clean everything up)
