UPDATING revision 1.177
1 $NetBSD: UPDATING,v 1.177 2008/08/13 16:37:56 christos Exp $ 2 3 This file (UPDATING) is intended to be a brief reference to recent 4 changes that might cause problems in the build process, and a guide for 5 what to do if something doesn't work. 6 7 For a more detailed description of the recommended way to build NetBSD 8 using build.sh, see the BUILDING file. 9 10 Note that much of the advice in this UPDATING file was written before 11 build.sh existed. Nevertheless, the advice here may be useful for 12 working around specific problems with build.sh. 13 14 See also: BUILDING, build.sh, Makefile. 15 16 Recent changes: 17 ^^^^^^^^^^^^^^^ 18 19 20080813: 20 MKDEBUG build was broken because the .depend files did not know 21 about .go files. You need to remove all .depend files and rebuild. 22 23 20080731: 24 WAPBL (metadata journaling support) has been added, but at this 25 time isn't backwards compatible with pre-WAPBL aware kernels 26 and userland (fsck_ffs in particular). Please make sure you 27 don't use a journaled filesystem with an older kernel/userland, 28 especially an uncleanly mounted journaled filesystem. WAPBL 29 also requires the super block to be in the UFS2 format. You 30 can use fsck_ffs -c 4 to update the superblock format. 31 32 20080721: 33 Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR 34 isn't defined. 35 36 20080531: 37 The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed 38 from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8) 39 utility needs to be rebuilt and reinstalled as older binaries 40 won't work correctly. The following sequence of commands: 41 42 $ (cd sys/sys/ && nbmake-$arch includes) 43 $ (cd sbin/drvctl/ && nbmake-$arch clean) 44 $ (cd sbin/drvctl/ && nbmake-$arch all) 45 46 leaves new drvctl utility in sbin/drvctl build directory. 47 48 20080503: 49 The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE. 50 51 20080521: 52 For a while, unprivileged UPDATE builds would fail to 53 succeed at the checkflist stage, complaining that 54 ${DESTDIR}/stand/<arch>/ did not exist. A fix for this 55 problem was committed to share/mk/bsd.kmodule.mk, revision 1.9. 56 If you already hit this problem, update the .mk file, 57 remove ${DESTDIR}/stand/<arch>, and re-run the build. 58 59 20080303: 60 Linker warnings are now fatal if $WARNS>0. 61 62 20080126: 63 The posix_fadvise system call has been changed from an assembly 64 stub, to a c file that calls an assembly stub. You need to 65 'rm -f posix_fadvise.* .depend' in the libc build directory to 66 avoid using the old assembly stub. 67 68 20071209: 69 The acpiec(4) driver has been split into two attachments. If you 70 get ACPI errors before the attachment, please update your kernel 71 configuration file appropriately or see GENERIC for more details. 72 73 20071115: 74 The it(4) driver has been renamed to itesio(4) and the old port 75 argument specified in the kernel configuration file is not valid 76 anymore. The itesio(4) driver now uses the Super I/O address port 77 rather than the EC address port. Please update your kernel 78 configuration file appropriately or see GENERIC for more details. 79 80 20071028: 81 The pccons(4) driver has been removed from the NetBSD/shark port. 82 You need to update any custom kernel configuration file you have 83 to remove any references to pccons (which includes removing the 84 now useless XSERVER option) and replace them with the correct 85 entries for the wscons driver. See the GENERIC configuration file 86 for more details. 87 88 20070913: 89 A latent bug in dhclient/dhcpd that caused it to be unable to 90 enumerate interfaces was fixed. The bug began to cause 91 problems after 20070911 when the kernel's SIOCGIFCONF 92 implementation was repaired. From 20070529 to 20070911 racoon 93 could not enumerate interfaces. (These are noted because 94 normal kernel/userspace version matching hygiene is not 95 sufficient to avoid this problem.) Ensure that both kernel 96 and userland are from after 20070913. 97 98 20070703: 99 nbinstall has been renamed as it calls the target specific and 100 the logic to pass down STRIP from mk been removed. This forces 101 a re-installation of tools. 102 103 20070422: 104 The way OS emulations lookup filenames inside the emulation root 105 has been changed. Rather than modify the pathname (and copy back 106 to userspace) namei() and lookup() directly check the emulation 107 root. One side effect is that absolute symlinks inside the emulated 108 root file system will be relative to that file system - unless they 109 start /../ this is useful when the emulated root is a real install 110 that has such links. 111 This might affect symlinks that have been added to reference outside 112 the emulated root. 113 114 20070412: 115 The pckbc driver on sgimips IP32 has been removed. Use macekbc 116 instead. See the GENERIC32_IP3x kernel configuration for an 117 example. 118 119 20070319: 120 src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so 121 on many platforms due to incorrect flags settings. If you 122 updated and built after about 20070315, do "nbmake-$arch 123 cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a 124 rebuild of object files that might have been built 125 incorrectly, and ensure that you have at least 126 src/lib/libc/Makefile 1.130. 127 128 20070210: 129 src/sys/sys/{sa.h,savar.h} were removed. 130 find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \ 131 | xargs egrep -l '/sa.h|/savar.h' | xargs rm 132 will allow dependencies on those files to get get rebuilt 133 134 20070209: 135 The threading model was changed when the newlock2 branch 136 was merged to NetBSD-current. If you boot with a new 137 kernel (version 4.99.10), then you also need a new pthread 138 library (/usr/lib/libpthread.so.0.7). If you boot with 139 an old kernel, then you need the old pthread library 140 (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and 141 the pthread library in sync, old threaded applications should 142 continue to work with an old or new kernel. Note that named(8) 143 is the only threaded application in the base system. 144 145 20061214: 146 Following the move of string_to_flags() and flags_to_string() 147 from the bin/ls/ sources to libutil, users doing UPDATE builds 148 will need to do a "make cleandir" in 149 tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/, 150 bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/, 151 usr.bin/xinstall/, libexec/ftpd/, rescue/, as well 152 as the installation images in distrib/ 153 in order to excise stale references to the old stat_flags.h header 154 file in the ls sources -- stat_flags.h has been removed. 155 156 20061108: 157 The configure script used in the src/tools/gcc compiler has been 158 changed to indicate that our libc has ssp support built-in and 159 does not depend on -lssp and -lssp-nonshared. You'll need to 160 make clean in src/tools/gcc first to rebuild the compiler. 161 162 20061009: 163 The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer 164 available. Use net.inet{,6}.tcp{,6}.congctl.selected instead. 165 166 20060814: 167 The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been 168 withdrawn. Use vidcvideo and pckbd instead. See the GENERIC 169 kernel configuration for an example. X servers from the last 170 few years should cope. 171 172 20060703: 173 MPACPI is no more. We always configure PCI interrupts using ACPI 174 if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed 175 to ACPI_SCANPCI. Thanks to work from fvdl. 176 177 20060627: 178 socket(2) has changed, and its system call has been versioned. 179 For userlands with the old version of socket(2), make sure that 180 your kernel has 'options COMPAT_30' set, or else 'bad system call' 181 errors will result. 182 183 Hints for a more successful build: 184 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 185 Use build.sh, but do not use its "expert mode": 186 This will automatically build the tools in the 187 correct order, and it will keep the tools and the 188 new build products from interfering with the running 189 system. This will allow you to ignore most of the 190 other advice in this file. 191 Build a new kernel first: 192 This makes sure that any new system calls or features 193 expected by the new userland will be present. This 194 helps to avoid critical errors when upgrading. 195 Use object directories: 196 This helps to keep stale object 197 files from polluting the build if a Makefile "forgets" 198 about one. It also makes it easier to clean up after 199 a build. It's also necessary if you want to use the 200 same source tree for multiple machines. 201 To use object directories with build.sh: 202 a) invoke build.sh with the "-M" or "-O" options. 203 To use object directories without using build.sh: 204 a) cd /usr/src ; make cleandir 205 b) Add "OBJMACHINE=yes" to /etc/mk.conf 206 c) Add "MKOBJDIRS=yes" to /etc/mk.conf 207 d) cd /usr/src ; make build 208 Note that running "make obj" in a directory will create 209 in obj.$MACHINE directory. 210 Build to a DESTDIR: 211 This helps to keep old installed files (especially libraries) 212 from interfering with the new build. 213 To build to a DESTDIR with build.sh, use the "-D" option. 214 To build to a DESTDIR without using build.sh, set the DESTDIR 215 environment variable before running make build. It should be 216 set to the pathname of an initially empty directory. 217 Problems: if you do not use build.sh, you might need to 218 update critical utilities without using DESTDIR since 219 nothing is executed from what is installed in DESTDIR. 220 (See critical utils, below.) 221 Build often: 222 This keeps critical utilities current enough to not choke 223 on any other part of the source tree that depends on up to 224 date functionality. If you use build.sh, you should not have 225 this problem. 226 227 What to do if things don't work: 228 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 229 When things don't work there is usually a few things that commonly 230 should be done. 231 1) make includes 232 This should be done automatically by make build. 233 2) cd share/mk && make install 234 Again, automatically done by make build. 235 236 Failsafe rebuild of a small part of the tree: 237 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 238 To make sure you rebuild something correctly you want to do 239 something like the following: 240 1) Make sure the includes and .mk files are up to date. 241 2) Make sure any program used to build the particular 242 utility is up to date. (yacc, lex, etc...) 243 3) cd ...path/to/util... 244 make cleandir 245 rm ...all obj directories... 246 make cleandir # yes, again 247 make obj 248 make depend && make 249 250 Failsafe rebuild of the entire tree: 251 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 252 If you really want to make sure the source tree is clean and 253 ready for a build try the following. Note that sourcing /etc/mk.conf 254 (a make(1) Makefile) in this manner is not right, and will not work 255 for anyone who uses any make(1) features in /etc/mk.conf. 256 257 ---cut here--- 258 #!/bin/sh 259 . /etc/mk.conf 260 261 if [ -z $NETBSDSRCDIR ] ; then 262 NETBSDSRCDIR=/usr/src 263 fi 264 if [ \! -d $NETBSDSRCDIR ] ; then 265 echo Unable to find sources 266 exit 1 267 fi 268 find $NETBSDSRCDIR -name \*.o -o -name obj.\* -o -name obj -exec rm \{\} \; 269 270 if [ -z $BSDOBJDIR ] ; then 271 BSDOBJDIR=/usr/obj 272 fi 273 if [ -d $BSDOBJDIR ] ; then 274 rm -rf $BSDOBJDIR 275 fi 276 277 cd $NETBSDSRCDIR && make cleandir 278 279 ---cut here--- 280 281 Critical utilities: 282 ^^^^^^^^^^^^^^^^^^^ 283 usr.bin/compile_et 284 usr.bin/make 285 usr.bin/yacc 286 usr.bin/lex 287 usr.bin/xlint 288 usr.bin/config 289 290 Other problems and possible solutions: 291 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 292 Symptom:Complaints involving a Makefile. 293 Fix: Rebuild usr.bin/make: 294 cd usr.bin/make && make && make install 295 Or, a failsafe method if that doesn't work: 296 cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin 297 298 Fix: Make sure .mk files are up to date. 299 cd share/mk && make install 300 301 Symptom:Kernel `config' fails to configure any kernel, including GENERIC. 302 Fix: Rebuild usr.bin/config 303 304 Symptom: 305 Fix: Rebuild usr.bin/yacc 306 307 Symptom: 308 Fix: Rebuild usr.bin/lex 309 310 Symptom: 311 Fix: rm /usr/lib/libbfd.a 312 313 Symptom:Obsolete intermediate files are used during compilation 314 Fix: Try the following sequence of commands in the directory in question. 315 make cleandir; rm `make print-objdir`; make cleandir; make obj 316 (If you built the tree without "make obj" in the past, obsolete files 317 may remain.
