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

213: ---cut here---

1.34 simonb 225: Other problems and possible solutions:
1.1 abs 226: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
227: Symptom:Unreasonable compiler errors.
228: Fix: Rebuild gnu/usr.bin/egcs
229:
230: Symptom:Complaints involving a Makefile.
1.17 erh 231: Fix: Rebuild usr.bin/make:
232: cd usr.bin/make && make && make install
233: Or, a failsafe method if that doesn't work:
234: cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
235:
1.1 abs 236: Fix: Make sure .mk files are up to date.
237: cd share/mk && make install
1.2 mrg 238:
239: Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
240: Fix: Rebuild usr.sbin/config
1.1 abs 241:
242: Symptom:
243: Fix: Rebuild usr.bin/yacc

247:
248: Symptom:
249: Fix: rm /usr/lib/libbfd.a
1.4 itojun 250:
251: Symptom:Obsolete intermediate files are used during compilation
252: Fix: Try the following sequence of commands in the directory in question.
253: make cleandir; rm `make print-objdir`; make cleandir; make obj
254: (If you built the tree without "make obj" in the past, obsolete files
255: may remain. The command tries to clean everything up)
