1.37 ! kristerw 1: $NetBSD: UPDATING,v 1.36 2001/09/25 02:26:13 tv 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.

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

268: (If you built the tree without "make obj" in the past, obsolete files
