UPDATING revision 1.8
1 $NetBSD: UPDATING,v 1.8 2001/01/01 14:13:51 sommerfeld Exp $ 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. 7 8 Recent changes: 9 ^^^^^^^^^^^^^^^ 10 11 20001230: 12 New share/mk files needed to support .WAIT in SUBDIR variables. 13 If you get make errors, 14 (cd share/mk; make install) 15 Also, PRINTOBJDIR has changed and is now used more heavily. 16 17 20001019: 18 The `ca' device driver has been replaced by `ld'; although the 19 major and minor numbers haven't changed, you should update your /dev 20 directory. 21 22 20000929: 23 The following make directives are obsoleted. 24 MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA 25 By default, RSA is built into libcrypto. IDEA and RC5 will not be 26 bulit into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build 27 additional library libcrypto_{idea,rc5}. 28 29 20000623: 30 MKCRYPTO and friends added to share/mk/bsd.own.mk. 31 'cd share/mk ; make install' needed before make build. 32 33 34 Hints for a more successful build: 35 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 36 Build a new kernel first: 37 This makes sure that any new system calls or features 38 expected by the new userland will be present. This 39 helps to avoid critical errors when upgrading. 40 Use object directories: 41 This helps to keep stale object 42 files from polluting the build if a Makefile "forgets" 43 about one. It also makes it easier to clean up after 44 a build. It's also necessary if you want to use the 45 same source tree for multiple machines. 46 To use object directories: 47 a) cd /usr/src ; make cleandir 48 b) Add "OBJMACHINE=yes" to /etc/mk.conf 49 c) Add "MKOBJDIRS=yes" to /etc/mk.conf 50 d) cd /usr/src ; make build 51 Note that running "make obj" in a directory will create 52 in obj.$MACHINE directory. 53 Build to a DESTDIR: 54 This helps to keep old 55 installed files (especially libraries) from interfering 56 with the new build. 57 To build to a DESTDIR, set the DESTDIR environment 58 variable before running make build. It should be set to 59 the pathname of an initially empty directory. 60 Problems: you might need to update critical utilities 61 without using DESTDIR since nothing is executed 62 from what is installed in DESTDIR. 63 (See critical utils, below) 64 Build often: 65 This keeps critical utilities current enough to not choke 66 on any other part of the source tree that depends on up to 67 date functionality. 68 69 What to do if things don't work: 70 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 71 When things don't work there is usually a few things that commonly 72 should be done. 73 1) make includes 74 This should be done automatically by make build. 75 2) cd share/mk && make install 76 Again, automatically done by make build. 77 78 Failsafe rebuild of a small part of the tree: 79 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 80 To make sure you rebuild something correctly you want to do 81 something like the following: 82 1) Make sure the includes and .mk files are up to date. 83 2) Make sure any program used to build the particular 84 utility is up to date. (yacc, lex, etc...) 85 3) cd ...path/to/util... 86 make cleandir 87 rm ...all obj directories... 88 make cleandir # yes, again 89 make obj 90 make depend && make 91 92 Failsafe rebuild of the entire tree: 93 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 94 If you really want to make sure the source tree is clean and 95 ready for a build try the following. Note that sourcing /etc/mk.conf 96 (a make(1) Makefile) in this manner is not right, and will not work 97 for anyone who uses any make(1) features in /etc/mk.conf. 98 99 ---cut here--- 100 #!/bin/sh 101 . /etc/mk.conf 102 103 if [ -z $BSDSRCDIR ] ; then 104 BSDSRCDIR=/usr/src 105 fi 106 if [ \! -d $BSDSRCDIR ] ; then 107 echo Unable to find sources 108 exit 1 109 fi 110 find $BSDSRCDIR -name \*.o -o -name obj.\* -o -name obj -exec rm \{\} \; 111 112 if [ -z $BSDOBJDIR ] ; then 113 BSDOBJDIR=/usr/obj 114 fi 115 if [ -d $BSDOBJDIR ] ; then 116 rm -rf $BSDOBJDIR 117 fi 118 119 cd $BSDSRCDIR && make cleandir 120 121 ---cut here--- 122 123 Critical utilities: 124 ^^^^^^^^^^^^^^^^^^^ 125 gnu/usr.bin/egcs 126 usr.bin/compile_et 127 usr.bin/make 128 usr.bin/yacc 129 usr.bin/lex 130 usr.sbin/config 131 132 Other problems and possibly solutions: 133 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 134 Symptom:Unreasonable compiler errors. 135 Fix: Rebuild gnu/usr.bin/egcs 136 137 Symptom:Complaints involving a Makefile. 138 Fix: Make sure .mk files are up to date. 139 cd share/mk && make install 140 Fix: Rebuild usr.bin/make 141 142 Symptom:Kernel `config' fails to configure any kernel, including GENERIC. 143 Fix: Rebuild usr.sbin/config 144 145 Symptom: 146 Fix: Rebuild usr.bin/yacc 147 148 Symptom: 149 Fix: Rebuild usr.bin/lex 150 151 Symptom: 152 Fix: rm /usr/lib/libbfd.a 153 154 Symptom:Obsolete intermediate files are used during compilation 155 Fix: Try the following sequence of commands in the directory in question. 156 make cleandir; rm `make print-objdir`; make cleandir; make obj 157 (If you built the tree without "make obj" in the past, obsolete files 158 may remain. The command tries to clean everything up) 159 160 Symptom:.../sysinst/run.c:xx: warning: initialization from incompatible pointer type 161 Fix: Rebuild and install usr.bin/menuc 162
