UPDATING revision 1.74
1 $NetBSD: UPDATING,v 1.74 2002/11/20 04:36:43 jschauma 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 20021011: 12 Systrace has been improved to support privilege elevation. 13 Updating the kernel requires the userland part of systrace 14 to be rebuild. 15 16 20021010: 17 The config(8) grammar was changed to allow options to register 18 dependencies on attributes, as well as other options. Users 19 must update and reinstall usr.sbin/config before building a new 20 kernel. 21 22 20021009: 23 A new attribute dependency syntax was introduced to config(8), 24 which is now used by the SCSI configuration description. Users 25 must update and reinstall usr.sbin/config before building a new 26 kernel. 27 28 20021003: 29 Several changes have been made to the autoconfiguration 30 framework. Users must update and reinstall usr.sbin/config 31 before building a new kernel. 32 33 20021001: 34 The i386mp branch has been merged. To compile a kernel, users 35 will need to add the option 'cpu* at mainbus?' to their configuration 36 file. Multiprocessor kernels will need 37 ioapic* at mainbus? apid ? 38 options MULTIPROCESSOR 39 options COM_MPLOCK 40 41 20020922: 42 MKDYNAMICROOT=yes enabled by default, which means that 43 certain shared libraries are installed into /lib, the shared 44 linker is installed into /libexec, and all programs in /bin 45 and /sbin are dynamically linked. 46 If you do not use "make build", you should ensure that 47 you have the libraries and shared linker in the new locations, 48 with: 49 make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so 50 51 20020917: 52 USE_NEW_TOOLCHAIN has been replaced with: 53 - TOOLCHAIN_MISSING -- set to "yes" on platforms for which 54 there is no working in-tree toolchain (hppa, ns32k, sh5, 55 x86_64). 56 - EXTERNAL_TOOLCHAIN -- if defined by the user, points to the 57 root ofan external toolchain (e.g. /usr/local/gnu). This 58 enables the cross-build framework even for TOOLCHAIN_MISSING 59 platforms. 60 61 20020906: 62 gehenna-devsw has been merged into the trunk. Need to update and 63 reinstall usr.sbin/config before build the kernel. 64 65 20020822: 66 Crunched rescue tools (contents of /bin and /sbin, plus others) 67 are now provided in /rescue. 68 69 To ensure that these are built statically linked (no matter 70 what the setting of LDSTATIC is), use a crunchgen(1) built 71 from sources newer than 20020820 (see the next entry). 72 73 20020820: 74 crunchgen(1) changed to ensure that the generated program 75 is statically linked. 76 77 Solution: update and reinstall usr.bin/crunch 78 79 20020515: 80 sshd user/group has been added. Need to hand add this in, or sshd 81 will not let you log in (with default, or UsePrivlegeSeparation=yes) 82 83 Add the following into /etc/group: 84 85 sshd:*:16: 86 87 and the following to /etc/master.passwd (via vipw): 88 89 sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin 90 91 also /var/chroot/sshd directory needs to be present (digged as a part of 92 build process). 93 94 20020426: 95 NBUILDJOBS obsoleted in favor of just using -j. 96 97 20020426: 98 etc/postinstall added, which performs various checks for 99 configuration file updates and changes, and can fix most of 100 the problems identified. 101 This should make it much easier to upgrade a system's 102 configuration from earlier systems (as far back as NetBSD 1.5). 103 104 20020320: 105 <bsd.lib.mk> needs a new install(1) for it's "-a cmd" support. 106 build and install at usr.bin/xinstall before the build. 107 108 20020319: 109 raw IPv6 socket now makes strict checking for sa_family and sa_len 110 on send(2) operation. be sure to have sbin/rtsol and usr.sbin/rtsold 111 newer than November 2001 when you upgrade the kernel. 112 113 20020311: 114 ssh configuration files were moved from /etc to /etc/ssh. Beware 115 if you restart your machine from remote. Note that sshd.conf needs 116 to be changed (due to the use of "/etc" inside). 117 118 20020223: 119 Users of the VAX port will need to rebuild and install gas 120 so it deal with the now present register prefix used in all 121 the VAX assembly files. 122 123 20020118: 124 125 ntpd user/group has been added. Need to hand add this in or builds 126 will break as mtree aborts early. 127 128 Add the following into /etc/group: 129 130 ntpd:*:15: 131 132 and the following to /etc/master.passwd (via vipw): 133 134 ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin 135 136 20011207: 137 138 If you're attempting to build a snapshot on sparc64 and are getting 139 reloc errors from the toolchain groff binary this means your native 140 toolchain has some broken C++ bits. 141 142 To fix: 143 144 Build a new toolchain (i.e. build.sh -t) 145 Use the new toolchain to build and install natively (i.e. /usr/lib) 146 147 gnu/lib/libgcc 148 gnu/lib/libstdc++ 149 150 After this a snapshot will be able to be built. 151 152 20011201: 153 In order for a sparc64 build to work you must have a working awk. If 154 you've built and installed a system with the new toolchain up to this 155 point you do not have a working awk as its ability to do floating 156 point is broken. 157 158 To build: 159 160 remake and install gnu/lib/libgcc 161 remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links 162 against the new libgcc.a) 163 164 20011128: 165 Kernel config information was changed to use defflag in 166 the various "files" files. Bug fixes to config(8) are 167 required in order for this to work properly. Make sure 168 to build and install in usr.sbin/config before attempting 169 to build a new kernel. 170 171 20011030: 172 libc/locale/wcstod.c now needs new lint(1). Update lint(1) 173 before building libc. 174 175 20011029: 176 The new document BUILDING.mdoc (view with nroff | more, or 177 see pre-generated .txt and .html versions) describes the build 178 procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN 179 build process, are intended in the long run to replace this 180 manual update log. 181 182 Users building a USE_NEW_TOOLCHAIN system should read the 183 BUILDING document for caveats. Generally, BUILDING supersedes 184 UPDATING for these systems, as tool updating is taken care of 185 by the new build system. 186 187 20011028: 188 src/etc/Makefile now needs install to be able to handle 189 symlinks that point to nowhere. A bug in install that 190 prevented this was corrected. 191 192 Solution: update and reinstall usr.bin/xinstall 193 Better Solution: Use the new toolchain and it will just work 194 for you. 195 196 20011006: 197 /etc/mtree/NetBSD.dist has been updated to take advantage of 198 absolute path support added to mtree(8). Older mtree(8)s don't 199 understand the format. 200 201 Solution: update and reinstall usr.sbin/mtree 202 203 20011004: 204 Crunchgen has been updated to work via reach-over makefiles. Updating 205 is suggested before running a snapshot build 206 207 20010915: 208 The new "ubcperf" code committed by Chuck Silvers removed 209 a header file, uvm/uvm_vnode.h. There may be stale .depend 210 files that still reference this file. 211 212 Solution: "make cleandir && make dependall" in affected 213 directories. 214 215 20010803: 216 grep.info is now built from grep.texi using makeinfo. Since it 217 requires makeinfo v4.0, you need to install new texinfo before 218 building gnu/usr.bin/grep. To install new texinfo, please follow 219 the instruction described in 20010726 entry. 220 221 20010803: 222 (i386 only): i386 kernel now uses new instructions like 223 `fxsave' which old gas doesn't understand. To build the 224 kernel successfully, you need to build and install a new toolchain, 225 (i.e., build.sh -t) or (temporarily) comment out "options I686_CPU" 226 from your kernel configuration until you rebuild your userland. 227 See 20011029 above and BUILDING file in this directory for more information. 228 [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled] 229 230 20010731: 231 Bootloader update on ELF platforms. DDB in kernels from before 232 this will be unable to read symbol tables provided by newer 233 bootloaders. 234 235 20010726: 236 Texinfo was updated to 4.0. To avoid failures when trying to 237 build the included texinfo files, do: 238 239 cd src/gnu/usr.bin/texinfo 240 make MKINFO=no dependall install 241 242 20010718: 243 Enabled correct .init/.fini processing in crt0. The way this 244 was done was to change a -I directive to cc(1), which means 245 make(1) will have a stale dependency (it will be checking the 246 timestamp on the wrong "dot_init.h"). 247 248 The symptom you will see is that new programs die with SIGSEGV 249 if you have a stale dependency. 250 251 Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so 252 before starting your build. 253 254 20010628: 255 A construct was added to uvm_page.h that uncovered a bug 256 in lint(1). If you get a warning/error about a non-portable 257 bitfield, update your lint(1) before proceeding. 258 259 20010226: 260 Added named user/group to system. Need to hand add this in or builds 261 will break as mtree aborts early. 262 263 To work around add by hand: 264 265 named:*:14: 266 267 to /etc/group and add: 268 269 named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin 270 271 to master.passwd (use vipw for instance if doing by hand). 272 273 Now a make build should progress. 274 275 20010219: 276 get/setprogname() added. Any hostprogs that may use this will need 277 to be bootstrapped manually until the host system is current. 278 279 Known problems: sys/arch/macppc/stand/fixcoff 280 usr.sbin/config (adding -DMAKE_BOOTSTRAP to 281 CFLAGS and rebuilding should work) 282 usr.sbin/mdsetimage - Build a static copy if 283 building a snapshot before fully bootstrapped. 284 285 20010204: 286 prepare the code to compile with stricter gcc flags. in 287 particular start eliminating redundant declarations. Yacc 288 needs to be installed before make build. 289 290 20010114: 291 introduce .if commands(target) in make(1). You need to 292 bring everything up-to-date first, then without installing 293 anything make and install in usr.bin/make, then proceed 294 with make build. 295 296 20010101: 297 bsd.subdir.mk committed 20001230 had a bug which caused 298 afterinstall targets to run too soon; update again. 299 300 20001230: 301 New share/mk files needed to support .WAIT in SUBDIR variables. 302 If you get make errors, 303 (cd share/mk; make install) 304 Also, PRINTOBJDIR has changed and is now used more heavily. 305 306 20001019: 307 The `ca' device driver has been replaced by `ld'; although the 308 major and minor numbers haven't changed, you should update your /dev 309 directory. 310 311 20000929: 312 The following make directives are obsoleted. 313 MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA 314 By default, RSA is built into libcrypto. IDEA and RC5 will not be 315 built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build 316 additional library libcrypto_{idea,rc5}. 317 318 319 Hints for a more successful build: 320 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 321 Build a new kernel first: 322 This makes sure that any new system calls or features 323 expected by the new userland will be present. This 324 helps to avoid critical errors when upgrading. 325 Use object directories: 326 This helps to keep stale object 327 files from polluting the build if a Makefile "forgets" 328 about one. It also makes it easier to clean up after 329 a build. It's also necessary if you want to use the 330 same source tree for multiple machines. 331 To use object directories: 332 a) cd /usr/src ; make cleandir 333 b) Add "OBJMACHINE=yes" to /etc/mk.conf 334 c) Add "MKOBJDIRS=yes" to /etc/mk.conf 335 d) cd /usr/src ; make build 336 Note that running "make obj" in a directory will create 337 in obj.$MACHINE directory. 338 Build to a DESTDIR: 339 This helps to keep old 340 installed files (especially libraries) from interfering 341 with the new build. 342 To build to a DESTDIR, set the DESTDIR environment 343 variable before running make build. It should be set to 344 the pathname of an initially empty directory. 345 Problems: you might need to update critical utilities 346 without using DESTDIR since nothing is executed 347 from what is installed in DESTDIR. 348 (See critical utils, below) 349 Build often: 350 This keeps critical utilities current enough to not choke 351 on any other part of the source tree that depends on up to 352 date functionality. 353 354 What to do if things don't work: 355 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 356 When things don't work there is usually a few things that commonly 357 should be done. 358 1) make includes 359 This should be done automatically by make build. 360 2) cd share/mk && make install 361 Again, automatically done by make build. 362 363 Failsafe rebuild of a small part of the tree: 364 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 365 To make sure you rebuild something correctly you want to do 366 something like the following: 367 1) Make sure the includes and .mk files are up to date. 368 2) Make sure any program used to build the particular 369 utility is up to date. (yacc, lex, etc...) 370 3) cd ...path/to/util... 371 make cleandir 372 rm ...all obj directories... 373 make cleandir # yes, again 374 make obj 375 make depend && make 376 377 Failsafe rebuild of the entire tree: 378 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 379 If you really want to make sure the source tree is clean and 380 ready for a build try the following. Note that sourcing /etc/mk.conf 381 (a make(1) Makefile) in this manner is not right, and will not work 382 for anyone who uses any make(1) features in /etc/mk.conf. 383 384 ---cut here--- 385 #!/bin/sh 386 . /etc/mk.conf 387 388 if [ -z $NETBSDSRCDIR ] ; then 389 NETBSDSRCDIR=/usr/src 390 fi 391 if [ \! -d $NETBSDSRCDIR ] ; then 392 echo Unable to find sources 393 exit 1 394 fi 395 find $NETBSDSRCDIR -name \*.o -o -name obj.\* -o -name obj -exec rm \{\} \; 396 397 if [ -z $BSDOBJDIR ] ; then 398 BSDOBJDIR=/usr/obj 399 fi 400 if [ -d $BSDOBJDIR ] ; then 401 rm -rf $BSDOBJDIR 402 fi 403 404 cd $NETBSDSRCDIR && make cleandir 405 406 ---cut here--- 407 408 Critical utilities: 409 ^^^^^^^^^^^^^^^^^^^ 410 gnu/usr.bin/egcs 411 usr.bin/compile_et 412 usr.bin/make 413 usr.bin/yacc 414 usr.bin/lex 415 usr.bin/xlint 416 usr.sbin/config 417 418 Other problems and possible solutions: 419 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 420 Symptom:Unreasonable compiler errors. 421 Fix: Rebuild gnu/usr.bin/egcs 422 423 Symptom:Complaints involving a Makefile. 424 Fix: Rebuild usr.bin/make: 425 cd usr.bin/make && make && make install 426 Or, a failsafe method if that doesn't work: 427 cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin 428 429 Fix: Make sure .mk files are up to date. 430 cd share/mk && make install 431 432 Symptom:Kernel `config' fails to configure any kernel, including GENERIC. 433 Fix: Rebuild usr.sbin/config 434 435 Symptom: 436 Fix: Rebuild usr.bin/yacc 437 438 Symptom: 439 Fix: Rebuild usr.bin/lex 440 441 Symptom: 442 Fix: rm /usr/lib/libbfd.a 443 444 Symptom:Obsolete intermediate files are used during compilation 445 Fix: Try the following sequence of commands in the directory in question. 446 make cleandir; rm `make print-objdir`; make cleandir; make obj 447 (If you built the tree without "make obj" in the past, obsolete files 448 may remain.
