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.

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

1.34 ! simonb 217: Other problems and possible solutions:
1.1 abs 218: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
219: Symptom:Unreasonable compiler errors.
220: Fix: Rebuild gnu/usr.bin/egcs
221:
222: Symptom:Complaints involving a Makefile.
1.17 erh 223: Fix: Rebuild usr.bin/make:
224: cd usr.bin/make && make && make install
225: Or, a failsafe method if that doesn't work:
226: cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
227:
1.1 abs 228: Fix: Make sure .mk files are up to date.
229: cd share/mk && make install
1.2 mrg 230:
231: Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
232: Fix: Rebuild usr.sbin/config

240: Symptom:
241: Fix: rm /usr/lib/libbfd.a
1.4 itojun 242:
243: Symptom:Obsolete intermediate files are used during compilation
244: Fix: Try the following sequence of commands in the directory in question.
245: make cleandir; rm `make print-objdir`; make cleandir; make obj
246: (If you built the tree without "make obj" in the past, obsolete files
247: may remain. The command tries to clean everything up)
