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

211: Other problems and possibly solutions:
212: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
213: Symptom:Unreasonable compiler errors.
214: Fix: Rebuild gnu/usr.bin/egcs
215:
216: Symptom:Complaints involving a Makefile.
1.17 erh 217: Fix: Rebuild usr.bin/make:
218: cd usr.bin/make && make && make install
219: Or, a failsafe method if that doesn't work:
220: cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
221:
1.1 abs 222: Fix: Make sure .mk files are up to date.
223: cd share/mk && make install
1.2 mrg 224:
225: Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
226: Fix: Rebuild usr.sbin/config
1.1 abs 227:
228: Symptom:

234: Symptom:
235: Fix: rm /usr/lib/libbfd.a
1.4 itojun 236:
237: Symptom:Obsolete intermediate files are used during compilation
238: Fix: Try the following sequence of commands in the directory in question.
239: make cleandir; rm `make print-objdir`; make cleandir; make obj
240: (If you built the tree without "make obj" in the past, obsolete files
241: may remain. The command tries to clean everything up)
