UPDATING revision 1.331
1 $NetBSD: UPDATING,v 1.331 2022/09/21 14:32:26 riastradh 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 Sections are marked with "^^^^^". After the section on "Recent changes" 15 are several sections containing more general information. 16 17 See also: BUILDING, build.sh, Makefile. 18 19 Recent changes: 20 ^^^^^^^^^^^^^^^ 21 22 20220921: 23 Since the kernel version was bumped to 9.99.100, the bootloader 24 must be updated on x86 and efiboot platforms in order to load 25 modules. 26 27 The kernel can still load modules at runtime with no bootloader 28 update. This will not affect release branches because it only 29 applies to patch numbers >100. 30 31 20220821: 32 Support for building extsrc/ has been deprecated. 33 EXTSRCSRCDIR and MKEXTSRC have been deprecated. 34 35 20220714: 36 Updates to xorg-server and associated drivers may cause builds to 37 fail. Cleaning both DESTDIR and the xorg build tree may be needed. 38 39 20220628: 40 Changes in the build of src/games/robots require a clean build 41 of that program. 42 43 20211116: 44 Changes in the xorg build require clean obj dirs for external/mit/xorg 45 (or a full clean/non-update build). 46 47 20211112: 48 Device tree sources were updated for evbarm. Some device nodes 49 (in particular, ld(4) devices on the ROCKPro64) will be renumbered. 50 51 20211014: 52 MKPIE default for aarch64 has changed, a clean build is required. 53 54 20210917: 55 Changed MNT_ACLS to default to POSIX1e ACLs instead of NFSv4 56 ACLs, to be compatible with FreeBSD. If you are using NFSv4 ACLs 57 and have "acls" in /etc/fstab you'll need to change it to "nfs4acls". 58 59 20210711: 60 Updated GMP sources may require cleaning in tools/gmp and/or in 61 external/lgpl3/gmp/lib, particularly if GCC itself does not build. 62 63 20210417: 64 GCC 10 was enabled for several platforms. If builds fail in either 65 tools/gcc or external/gpl/gcc, first try cleaning those objects and 66 removing the $DESTDIR/usr/include/g++ subdirectory. 67 68 20201230: 69 lint1/ops.c is no longer autogenerated. If this makes the build 70 fail, clean $OBJDIR/tools/*lint* and $OBJDIR/usr.bin/*xlint*. 71 72 20201016: 73 MIPS kernel modules have been disabled until they work. This will 74 turn up in extra files in the DESTDIR, which should be cleaned. 75 76 20200925: 77 GNU MPC and MPFR have been updated. At least MPFR needs cleaning 78 in both the tools and external dirs. 79 80 20200912: 81 GCC 9 has arrived for Arm and x86 platforms, and will be coming 82 for several more, as will binutils 2.34. Clean as required. 83 84 20200907: 85 GCC 9 is coming, and binutils has been updated for MIPS. This 86 probably requires cleaning the tools/binutils. 87 88 20200811: 89 GCC updates may require cleaning the objdir. This may occur 90 due to GCC 7.5 update, GCC 8.4 move to gcc.old, or the upcoming 91 GCC 9 upgrade. 92 93 20200614: 94 blacklist* has been renamed to blocklist*. postinstall(8) 95 should handle the migration 96 97 20200601: 98 Due to a mistake in LIBISPRIVATE handling, .so libraries were 99 created in the build directories and need cleaning. 100 101 20200311: 102 GCC 8 ports will need cleaning in src/tools/gcc and 103 src/external/gpl3/gcc due to GCC 8.4 update. 104 105 20191118: 106 More architectures were switched to gcc8: 107 i386, ia64 powerpc64, sparc, sparc64, arm 108 The same comments as in 20191022 apply. 109 110 20191112: 111 The LLVM update requires a clean rebuild for all architectures using 112 LLVM during the tools build phase (i386, amd64, aarch64). 113 114 20191022: 115 Ports amd64 and aarch64 switched to GCC 8.3 by default. 116 In-place ("expert mode", build.sh -E) builds are not supported 117 when going from a GCC 7 userland to GCC 8. Do a regular 118 build to a different DESTDIR (or preferably: build.sh -U) at least 119 once and install sets, or download comp.{tar.xz,tgz} from the 120 daily builds and install that before doing the next in-place build. 121 122 20191001: 123 GCC 8.3 was imported. Builds of src/tools/gcc may fail if 124 old builds with GCC 7 output now uses GCC 8. Clean this 125 directory, and also clean src/external/gpl3/gcc. 126 127 20190903: 128 Files with names that coincide with existing files' names on 129 case-insensitive file systems were inadvertently committed, for 130 radeon GPU firmware. We cannot mark these as obsolete for 131 postinstall to fix, so if you updated src since 2019-08-26, and 132 ran build.sh distribution or ran build.sh release, you must 133 manually delete the following files in your DESTDIR (which is 134 usually $OBJDIR/destir.$ARCH), or from / if you have installed 135 them: 136 137 /libdata/firmware/radeon/bonaire_ce.bin 138 /libdata/firmware/radeon/bonaire_mc.bin 139 /libdata/firmware/radeon/bonaire_me.bin 140 /libdata/firmware/radeon/bonaire_mec.bin 141 /libdata/firmware/radeon/bonaire_pfp.bin 142 /libdata/firmware/radeon/bonaire_rlc.bin 143 /libdata/firmware/radeon/bonaire_sdma.bin 144 /libdata/firmware/radeon/bonaire_smc.bin 145 /libdata/firmware/radeon/bonaire_uvd.bin 146 /libdata/firmware/radeon/hainan_ce.bin 147 /libdata/firmware/radeon/hainan_mc.bin 148 /libdata/firmware/radeon/hainan_me.bin 149 /libdata/firmware/radeon/hainan_pfp.bin 150 /libdata/firmware/radeon/hainan_rlc.bin 151 /libdata/firmware/radeon/hainan_smc.bin 152 /libdata/firmware/radeon/hawaii_ce.bin 153 /libdata/firmware/radeon/hawaii_mc.bin 154 /libdata/firmware/radeon/hawaii_me.bin 155 /libdata/firmware/radeon/hawaii_mec.bin 156 /libdata/firmware/radeon/hawaii_pfp.bin 157 /libdata/firmware/radeon/hawaii_rlc.bin 158 /libdata/firmware/radeon/hawaii_sdma.bin 159 /libdata/firmware/radeon/hawaii_smc.bin 160 /libdata/firmware/radeon/kabini_ce.bin 161 /libdata/firmware/radeon/kabini_me.bin 162 /libdata/firmware/radeon/kabini_mec.bin 163 /libdata/firmware/radeon/kabini_pfp.bin 164 /libdata/firmware/radeon/kabini_rlc.bin 165 /libdata/firmware/radeon/kabini_sdma.bin 166 /libdata/firmware/radeon/kaveri_ce.bin 167 /libdata/firmware/radeon/kaveri_me.bin 168 /libdata/firmware/radeon/kaveri_mec.bin 169 /libdata/firmware/radeon/kaveri_mec2.bin 170 /libdata/firmware/radeon/kaveri_pfp.bin 171 /libdata/firmware/radeon/kaveri_rlc.bin 172 /libdata/firmware/radeon/kaveri_sdma.bin 173 /libdata/firmware/radeon/mullins_ce.bin 174 /libdata/firmware/radeon/mullins_me.bin 175 /libdata/firmware/radeon/mullins_mec.bin 176 /libdata/firmware/radeon/mullins_pfp.bin 177 /libdata/firmware/radeon/mullins_rlc.bin 178 /libdata/firmware/radeon/mullins_sdma.bin 179 /libdata/firmware/radeon/oland_ce.bin 180 /libdata/firmware/radeon/oland_mc.bin 181 /libdata/firmware/radeon/oland_me.bin 182 /libdata/firmware/radeon/oland_pfp.bin 183 /libdata/firmware/radeon/oland_rlc.bin 184 /libdata/firmware/radeon/oland_smc.bin 185 /libdata/firmware/radeon/pitcairn_ce.bin 186 /libdata/firmware/radeon/pitcairn_mc.bin 187 /libdata/firmware/radeon/pitcairn_me.bin 188 /libdata/firmware/radeon/pitcairn_pfp.bin 189 /libdata/firmware/radeon/pitcairn_rlc.bin 190 /libdata/firmware/radeon/pitcairn_smc.bin 191 /libdata/firmware/radeon/tahiti_ce.bin 192 /libdata/firmware/radeon/tahiti_mc.bin 193 /libdata/firmware/radeon/tahiti_me.bin 194 /libdata/firmware/radeon/tahiti_pfp.bin 195 /libdata/firmware/radeon/tahiti_rlc.bin 196 /libdata/firmware/radeon/tahiti_smc.bin 197 /libdata/firmware/radeon/verde_ce.bin 198 /libdata/firmware/radeon/verde_mc.bin 199 /libdata/firmware/radeon/verde_me.bin 200 /libdata/firmware/radeon/verde_pfp.bin 201 /libdata/firmware/radeon/verde_rlc.bin 202 /libdata/firmware/radeon/verde_smc.bin 203 204 We will re-import these radeon firmware images another way 205 later. 206 207 20190727: 208 The uefi bootloader has gained tftp support and needs a clean 209 build. If you do update builds, manually clean its object 210 directory by something like: 211 cd sys/arch/i386/stand/efiboot && make clean 212 213 20190723: 214 The jemalloc allocator in libc is now build without extended 215 debugging (for performance reasons). In update builds make sure 216 to rebuild it completely, by removing all affected object files, 217 including compat builds, something like: 218 cd /usr/obj && find . -type d -name jemalloc|xargs rm -rf 219 220 20190207: 221 GCC 7 switched for many ports. Update builds are likely to fail. 222 223 20180924: 224 A newer OpenSSL version has been imported. If you are doing 225 update builds, make sure to remove all old obj dirs, like: 226 cd /usr/obj && find . -type d -name openssl | xargs rm -rf 227 228 20180717: 229 On aarch64 int64_t and related types have changed from long long 230 to long. This requires recompiling all C++ binaries. 231 232 20180713: 233 On amd64 and i386 static binaries are now build position 234 independend. This requires recompilation of all object 235 files used to create the crunched /rescue binary. 236 Clean the rescue directory in your obj directory before 237 doing an update build, otherwise linking will fail. 238 239 20180414: 240 Existing binutils was migrated to binutils.old. Manual 241 removal of tools/binutils objects directory may be required 242 to fix tools build failure. 243 244 20180311: 245 bdftopcf was updated and may need cleaning in the 246 src/external/mit/xorg/tools/bdftopcf subdirectory if there are 247 link errors. 248 249 20180212: 250 between OpenSSL and GCC updates, many things may fail to build. 251 any failure that looks like GCC or openssl is best handled by 252 a clean destdir and objdir. Full cleandir and destdir deletion 253 is recommended if build failures occur. 254 255 20171225: 256 removal of the vadvise syscall requires manual removal of all 257 associated files from the libc build object directory (including 258 the .depend files) - a command like: 259 cd $OBJ && find . -type d -name libc | xargs rm -rf 260 For architectures that support multiple "compat" binary targets, 261 you'll need to cleanup both the regular libc directory and the 262 compat ones (the above command will do that). 263 264 20171010: 265 a change to the build structure of external/bsd/acpica/bin/iasl 266 means that its objdir (or *.d and .depend at least) might need 267 to be manually removed - or a build done once without -u. 268 269 20170822: 270 a new version of GMP has been imported and probably 271 will break parts of builds related to themselves or GCC, both 272 in the tools and the native section. Remove all GCC, GMP, MPFR 273 and MPC objdirs or build once without -u. 274 275 20170816: 276 a new version of MPFR and MPC have been imported and probably 277 will break parts of builds related to themselves or GCC, both 278 in the tools and the native section. Remove all GCC, GMP, MPFR 279 and MPC objdirs or build once without -u. 280 281 20170402: 282 a new version of dhcpcd has been imported, which does not support 283 update builds from the previous version. Remove your 284 external/bsd/dhcpcd object dir or build once without -u. 285 286 20170211: 287 a new terminfo database has been imported. 288 The structure of it has changed slightly from prior versions and 289 an updated tic tool is required. 290 If you build.sh, don't use -u 291 292 20170207: 293 various arch dependent libc/exect.S files were removed 294 Either remove the obj directories (lib/libc and compat/amd64/i386/lib 295 if it exists) or do a clean build. 296 (This is a bug in the make system, it should be corrected without 297 human intervention, but isn't.) 298 299 20170104: 300 xinput build options have changed. 301 Remove the obj directory (external/mit/xorg/bin/xinput) 302 if you build.sh -u 303 304 20170103: 305 a new version of flex has been imported. 306 Remove the file from obj (external/bsd/flex) 307 if you build.sh -u 308 309 20161014: 310 a new version of OpenSSL has been imported. 311 Remove the files from obj (crypto/external/bsd/openssl) 312 if you build.sh -u 313 314 20161009: 315 a new version of dhcpcd has been imported with slightly changed 316 build infrastructure. When doing a build.sh -u this requires 317 pruning the external/bsd/dhcpcd objdir. 318 319 20160914: 320 i386, amd64, shark, ofppc and macppc have joined shark and x68k 321 ports in using xorg-server 1.18. This requires a clean destdir 322 and a clean objdir. 323 324 20160527: 325 i386 needs a full cleandir or objdir deletion because PIE has 326 been enabled. (see the amd64 entry two down for further info) 327 328 20160418: 329 libedit needs manual removal of all autogenerated files since 330 some of them are not autogenerated anymore. Remember that there 331 might be two copies of libedit if your platform builds "compat". 332 333 20160410: 334 amd64 needs full "make cleandir" or deletion of objdir now that 335 PIE has been enabled for amd64. PIE, or position-independent 336 executables, means all code, including executables and not just 337 shared libraries, is position-independent and hence able to be 338 relocated by ASLR, address space layout randomization. 339 340 The change was made in Makefile variables for compiler and 341 linker flags, for which make(1) does not record dependencies, 342 hence it is unable to detect that all .o files need rebuilding. 343 344 Partial rebuilds with some modified source files will likely 345 fail when linking executables, since the linker refuses to mix 346 position-independent code with position-dependent code in 347 position-independent executables: 348 349 .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC 350 351 20160401: 352 Ports switching to GCC 5.3 will need a full "make cleandir". 353 Some people have found that cleandir is not sufficient, so if 354 in doubt delete the entire object directory tree for gcc. 355 356 20160306: 357 NetBSD's regexp implementation is now part of libnbcompat. 358 Nblex, nbm4, nbpax, nbsed use it and they may crash on 359 non-NetBSD hosts if linked with stale object files produced 360 while they included a non-NetBSD regex.h. 361 In any case, you should "make cleandir" at least these tools 362 before updating your toolchain. 363 364 20160125: 365 Dtrace has been enabled by default on some architectures. 366 When doing an update build, make sure to clean the etc/mtree 367 object directory before starting the build - otherwise the 368 needed directories in destdir will not be created. 369 An easy way to do this is: 370 cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir 371 372 20150818: 373 New acpica requires "make cleandir" in src/external/bsd/acpica 374 again. 375 376 20150413: 377 New acpica requires "make cleandir" and reinstalling yacc 378 in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and 379 also "make cleandir" in /usr/src/external/bsd/acpica. 380 381 20150404: 382 Lint changes require a full rebuild of the tool, so make 383 sure to build without -u option to build.sh, or manually 384 do a make cleandir in src/tools/lint1 and 385 src/usr.bin/xlint. 386 387 20150310: 388 Improvements to openssl for arm mean that update builds of 389 the openssl libraries will fail. A make cleandir in 390 external/bsd/openssl/lib is needed 391 392 20141026: 393 A mishap during the import of pppd may cause your corruption 394 in your cvs directory if you happened to do a cvs update 395 during a short period of time. To fix, just remove the 396 directory src/external/bsd/ppp/dist/pppd completely 397 and let cvs restore it on next update. 398 399 20140721: 400 The src/external/mit/lua/src directory was accidentally created 401 and then deleted in the CVS repository. If you get errors like 402 403 cvs [update aborted]: cannot open directory 404 /cvsroot/src/external/mit/lua/src: No such file or directory 405 406 then delete your local copy of that directory tree and try again. 407 408 20140530: 409 ARM eABI switched to DWARF based exception handling. This requires 410 rebuilding all C++ code. It is strongly advised to do a clean build. 411 412 20140131: 413 The new compiler_rt/libc integration moved a few things. It is strongly 414 advised to do a clean build. At least lib/libc, the compat version(s) 415 of libc, libkern, rump and the kernels need to be cleaned. 416 417 20131227: 418 1. The new ntpd runs in a restricted mode to prevent amplification 419 attacks. If you need ntpdc to work you need to explicitly enable 420 mode7 in your config file. Make sure you put the necessary restrict 421 statements to avoid being exposed. 422 2. strncat has moved from lib/libc to common/lib/libc; you might need 423 to make clean in libc 424 425 20131129: 426 The GMP sources were updated, and builds will likely fail without 427 cleaning their build trees for both tools and in-tree, like below. 428 429 20131128: 430 The MPC and MPFR sources were updated, and builds may require their 431 tools and in-tree directories cleaned for successful updates. 432 433 20130605: 434 The kernel option FAST_IPSEC no longer exists, it's been renamed 435 to IPSEC (and the older IPSEC version removed). 436 437 20130605: 438 Previous freetype installations erroneously installed private 439 header files. If you are building against a non-empty $DESTDIR, 440 please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/. 441 442 20130531: 443 The xdm update may cause build failure due to xdm.man being 444 in the obj tree. Make sure to ensure any like this: 445 nbmake: nbmake: don't know how to make xdm.man. Stop 446 is fixed by deleting the xdm.man in the obj tree. 447 448 20130530: 449 Updates of many xsrc packages will leave old .pc files around. 450 Best to clean out the xsrc objdir entirely before rebuilds. 451 452 20130301: 453 The removal of netiso requires manual removal of /usr/include/netiso 454 prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump} 455 456 20120726: 457 The update of OpenSSL requires cleaning both the OpenSSL build 458 directory and DESTDIR. *Even non-update builds require cleaning 459 DESTDIR.* Builds done without taking these steps may fail, or in 460 some cases may succeed and install broken OpenSSL libraries that 461 cause third-party software to link incorrectly and/or crash. 462 463 20120507: 464 The database schema for makemandb was changed. You will 465 need to update the database using 'makemandb -f' or wait 466 for the next weekly run to fix it. 467 468 20120319: 469 sys/conf/Makefile.kern.inc has been modified to adjust the 470 size of db_symtab automatically. You need to update dbsym in 471 your $TOOLDIR to build kernels with options SYMTAB_SPACE. If 472 you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your 473 mk.conf. 474 475 20120216: 476 Default for MKCATPAGES changed to NO. Update builds will fail 477 unless DESTDIR is cleaned manually. If you built between 20120207 478 and 20120216, daily and weekly could have created an unreadable 479 /var/db/man.db index for apropos. Running makemandb -f or 480 the next run of weekly will fix it. 481 482 20111227: 483 If you built between 20111225 and 20111227 you need to remove 484 /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the 485 bump has been reverted. 486 487 20111125: 488 The "rnd" pseudodevice has been added to sys/conf/std, which 489 means it should no longer be explicitly listed in kernel 490 configuration files. The line "pseudo-device rnd" should be 491 removed from any custom kernel config files users may have. 492 493 20111119: 494 A problem with the datastructures used by the rndctl(8) 495 utility (pointers in datastructures in an array, making 32->64 496 bit compatibility very painful) has been fixed in a 497 non-backwards-compatible way. If you replace your kernel, 498 replace your rndctl executable too. 499 500 20111001: 501 the prop_*_send_syscall() functions from proplib(3) have been 502 changed and their new version is not backward compatible with the old 503 one. So ensure that all consumers of these functions (currently: 504 quota2 code and its tests) are updated together with the new lib. 505 506 20110817: 507 sparc has been changed to use GCC 4.5.3, so any objdir or 508 DESTDIR for them should be deleted before updating. 509 510 20110806: 511 i386 and amd64 have been changed to use GCC 4.5.3, so any 512 objdir or DESTDIR for them should be deleted before updating. 513 514 20110805: 515 The update to GCC 4.5.3 requires a non-trivial portion of 516 the tree to be cleaned. Best to delete both objdir and 517 DESTDIR before running this update. So far, only the 518 sparc64, mips and powerpc platforms have changed. 519 520 20110803: 521 The layout of external/public-domain/xz has changed. To do an 522 update build you will have to remove the contents of the OBJDIR 523 for external/public-domain/xz/bin by hand as the xz entry there 524 is now a directory. 525 526 20110410: 527 The configuration of src/tools/gcc has changed. To do an 528 update build you have to clean both tools/binutils and 529 tools/gcc by hand. 530 531 20110328: 532 Building the Xorg binary was moved into a subdirectory to fix 533 ordering issues with "make all". It may be necessary to remove 534 the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86 535 if your update build fails, as the "Xorg" entry there is now a 536 directory. 537 538 20110121: 539 Assembler files no longer use -traditional-cpp. This can break 540 the build of individual parts of the tree. This is handled 541 correctly by build.sh. Manual builds have to update /usr/share/mk 542 and re-run config(1) for any kernel configurations as needed. 543 544 20101217: 545 The tcpdump(8) program was changed to drop privileges and chroot(2) 546 by default. It may be necessary to manually update passwd(5) and 547 group(5) in order to make the program work with existing setups. 548 549 20101125: 550 The latest changes to setenv(3) disallow setting environment 551 variables with names that contain '='. Revision 1.18 of env.c 552 assumed that this was allowed. Installing a new libc with an 553 old copy of /usr/bin/env causes env x=1 printenv | grep x= to 554 break which affects the autoconf tests for dependency finding, 555 so building gcc will end up printing: 556 checking dependency style of gcc... none 557 configure: error: no usable dependency style found 558 Fix it by rebuilding and re-installing env. 559 560 20101119: 561 Recent Xorg updates in xsrc/external/mit/ may cause various build 562 or run-time problems. Delete your entire DESTDIR and OBJDIR if you 563 have any build problems with xsrc, or problems with mismatched 564 versions between xorg-server and drivers. 565 566 20100604: 567 The update of ATF to 0.9 causes old tests written in shell to fail 568 unless they are rebuilt. If you are building with MKUPDATE=yes, 569 you need to clean the src/external/bsd/atf/tests/ and the src/tests/ 570 trees by hand. 571 572 20100522: 573 Recent Xorg updates in xsrc/external/mit/ will cause various build 574 problems. Delete your entire DESTDIR and OBJDIR if you have any 575 build problems with xsrc. 576 577 20100522: 578 private section of <ctype.h> was split, and now mklocale(1) 579 include ctype_local.h, so you have to make cleandir in tools/mklocale. 580 581 20100520: 582 The location of the xkb compiled descriptions has changed. Please 583 remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR. 584 585 20100222: 586 The shared objects file extension has been changed from .so to 587 .pico, in order to avoid conflicts with shared libraries names 588 libXX.so. All now stale regular .so files can be removed from 589 your object directories. 590 591 20100204: 592 The termcap database has been removed from the sources, 593 but has not been marked obsolete so it is not removed 594 from the system when upgrading. 595 As such, you will need to remove them from your object 596 and destination directories. 597 598 20091101: 599 After updating, it may be necessary to make the 'cleandir' 600 target in src/tools/yacc/ and in src/usr.bin/yacc/ before a 601 'build.sh -u tools' or 'build.sh -u distribution'. Ditto 602 src/tools/lex/ and src/usr.bin/lex/. 603 604 20091001: 605 On amd64 you must rebuild tools (to get the new binutils) 606 before building a kernel, or the build fails on cpufunc.S. 607 608 20091001: 609 An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb 610 symlink, failing the build. Delete the link, and the subdir 611 it is in, and retry your build. 612 613 20090718: 614 libc build changed so that strchr() provides the extra entry 615 point for index(). Update build of libc.a (and libc_pic.a) 616 may fail because the archive contains the unwanted index.o. 617 (Similarly for strrchr() and rindex().) 618 619 20090709: 620 Native Xorg was upgraded again. Builds will probably fail again 621 without a clean objdir, at least for src/external/mit/xorg. 622 623 20090616: 624 Native Xorg was upgraded. Builds will need a clean objdir for 625 src/external/mit/xorg. Upgrading a system from sets will not 626 work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc 627 subdirectory has been changed into a file, and this needs to 628 be manually "rm -r"'ed before installing xbase.tgz. 629 630 20090501: 631 Several new functions were added to string.h/libc, and this 632 can cause autoconf problems during the tool build for people 633 who fail to clean out their tools objects properly. If you 634 note messages about stpcpy, stpncpy or strnlen accompanying a 635 failure during the tool build, clean out all your tools 636 objects and start again. 637 638 20090325: 639 The i386 port was switched to i486 default toolchain. This requires 640 cleaning your src/tools directory and $TOOLDIR and rebuilding them. 641 642 20090126: 643 The __posix_fadvise50 system call changed assembly stub type. You 644 need to 'rm -f __posix_fadvise50.*' in the libc build directory 645 to avoid using the old assembly stub. 646 647 20090202: 648 pkg_install now depends on the pkgdb cache for automatic conflict 649 detection. It is recommended to rebuild the cache with 650 ``pkg_admin rebuild''. 651 652 20090110: 653 time_t and dev_t have been bumped to 64 bit quantities. To upgrade: 654 1. Make sure your kernel has COMPAT_50 in it. Build and install. 655 This is needed even in the MODULAR kernel because there is 656 conditionally compiled code in rtsock.c. 657 2. make sure build.sh completes and the binaries in a chroot work 658 before installing. 659 3. If you don't use build.sh and you build directly to root, and 660 your build breaks in the middle, don't despair. Make sure headers 661 are installed properly, and start building libraries first libc 662 and libutil, install them and then continue building all the 663 libraries in src/lib and src/gnu/lib and install them. Once 664 the new libraries are installed, you can restart the build. 665 4. If you compile packages and you notice link time warnings, 666 rebuild the required packages to update their shared libraries. 667 Any package you rebuild will require rebuilding all the packages 668 that depend on it. 669 5. Next time you run pwd_mkdb with the new binary, the file 670 will be upgraded and it will not be backwards compatible. 671 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see 672 lastlogx(5)) have been versioned, and there is a heuristic 673 for utmp. You are better off removing the old files after 674 upgrading. The automated clearing of /var/run during 675 boot, and the automated rotating of files in /var/log by 676 newsyslog(8), may mean that you do not have to remove the 677 files manually. 678 7. The optional accounting file (/var/account/acct, see 679 accton(8)) has not been versioned, and will need to be 680 removed. The automatic rotation of the accounting file by 681 /etc/daily limits the bad consequences of failure to remove 682 the file. 683 8. Application software that writes time_t to binary files on 684 disk will break or need attention. Most notably: if you are 685 using PostgreSQL < 8.4, you need to dump your databases, 686 rebuild PostgreSQL with the new time_t, then restore. 687 688 20081219: 689 config(1) has been updated, and one of the files it creates - 690 swapnetbsd.o - has changed format. You need to rebuild config 691 (done automatically by build.sh) and then you need to rerun 692 config on all kernel configuration files before rebuilding those 693 kernels. 694 695 20081205: 696 If you build with MKX11=no, you should remove /etc/rc.d/xdm and 697 /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc 698 set and will appear as extra files for MKX11=no update builds. 699 700 20081122: 701 On i386, various kernel options(4) in GENERIC including 702 file systems have been disabled and moved into kernel modules. 703 Before trying a new GENERIC kernel, you have to prepare the 704 following files as well as a new GENERIC kernel: 705 706 - build and install kernel modules from src/sys/modules 707 708 - install the latest bootloader, which will load a module 709 for the file system from which the kernel is loaded automatically 710 711 If you have to load your kernel from a file system which is not of 712 the same type as the root file system, you have to load the necessary 713 file system module manually on the boot prompt or in the boot.cfg file. 714 715 20080827: 716 If you built and installed a libc from sources between 717 2008/08/20 and 2008/08/26 you got a broken strtouq(3) 718 which results in false errors reported by lint(1). 719 Since this breaks the libc build itself, manual help is 720 needed -- lint must be disabled temporarily, e.g.: 721 $ (cd lib/libc && make MKLINT=no dependall install) 722 723 20080813: 724 MKDEBUG build was broken because the .depend files did not know 725 about .go files. You need to remove all .depend files and rebuild. 726 727 20080802: 728 A regression in binary compatibility for pthread_mutex_t has 729 been fixed. Unfortunately, the price is breaking compatibility 730 for -current. 731 732 Threaded programs (using libpthread) and C++ programs (using 733 libstdc++) compiled after 20070907 and before 20080802 need to 734 be recompiled. 735 736 One way to find affected pkgsrc packages: 737 738 $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO 739 $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO 740 741 20080731: 742 WAPBL (metadata journaling support) has been added, but at this 743 time isn't backwards compatible with pre-WAPBL aware kernels 744 and userland (fsck_ffs in particular). Please make sure you 745 don't use a journaled filesystem with an older kernel/userland, 746 especially an uncleanly mounted journaled filesystem. WAPBL 747 also requires the super block to be in the UFS2 format. You 748 can use fsck_ffs -c 4 to update the superblock format. 749 750 20080721: 751 Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR 752 isn't defined. 753 754 20080531: 755 The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed 756 from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8) 757 utility needs to be rebuilt and reinstalled as older binaries 758 won't work correctly. The following sequence of commands: 759 760 $ (cd sys/sys/ && nbmake-$arch includes) 761 $ (cd sbin/drvctl/ && nbmake-$arch clean) 762 $ (cd sbin/drvctl/ && nbmake-$arch all) 763 764 leaves new drvctl utility in sbin/drvctl build directory. 765 766 20080503: 767 The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE. 768 769 20080521: 770 For a while, unprivileged UPDATE builds would fail to 771 succeed at the checkflist stage, complaining that 772 ${DESTDIR}/stand/<arch>/ did not exist. A fix for this 773 problem was committed to share/mk/bsd.kmodule.mk, revision 1.9. 774 If you already hit this problem, update the .mk file, 775 remove ${DESTDIR}/stand/<arch>, and re-run the build. 776 777 20080303: 778 Linker warnings are now fatal if $WARNS>0. 779 780 20080126: 781 The posix_fadvise system call has been changed from an assembly 782 stub, to a c file that calls an assembly stub. You need to 783 'rm -f posix_fadvise.* .depend' in the libc build directory to 784 avoid using the old assembly stub. 785 786 20071209: 787 The acpiec(4) driver has been split into two attachments. If you 788 get ACPI errors before the attachment, please update your kernel 789 configuration file appropriately or see GENERIC for more details. 790 791 20071115: 792 The it(4) driver has been renamed to itesio(4) and the old port 793 argument specified in the kernel configuration file is not valid 794 anymore. The itesio(4) driver now uses the Super I/O address port 795 rather than the EC address port. Please update your kernel 796 configuration file appropriately or see GENERIC for more details. 797 798 20071028: 799 The pccons(4) driver has been removed from the NetBSD/shark port. 800 You need to update any custom kernel configuration file you have 801 to remove any references to pccons (which includes removing the 802 now useless XSERVER option) and replace them with the correct 803 entries for the wscons driver. See the GENERIC configuration file 804 for more details. 805 806 20070913: 807 A latent bug in dhclient/dhcpd that caused it to be unable to 808 enumerate interfaces was fixed. The bug began to cause 809 problems after 20070911 when the kernel's SIOCGIFCONF 810 implementation was repaired. From 20070529 to 20070911 racoon 811 could not enumerate interfaces. (These are noted because 812 normal kernel/userspace version matching hygiene is not 813 sufficient to avoid this problem.) Ensure that both kernel 814 and userland are from after 20070913. 815 816 20070703: 817 nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It 818 calls the target-specific strip program, and the logic to pass 819 down STRIP from make has been removed. This requires a 820 re-installation of tools. 821 822 20070422: 823 The way OS emulations lookup filenames inside the emulation root 824 has been changed. Rather than modify the pathname (and copy back 825 to userspace) namei() and lookup() directly check the emulation 826 root. One side effect is that absolute symlinks inside the emulated 827 root file system will be relative to that file system - unless they 828 start /../ this is useful when the emulated root is a real install 829 that has such links. 830 This might affect symlinks that have been added to reference outside 831 the emulated root. 832 833 20070412: 834 The pckbc driver on sgimips IP32 has been removed. Use macekbc 835 instead. See the GENERIC32_IP3x kernel configuration for an 836 example. 837 838 20070319: 839 src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so 840 on many platforms due to incorrect flags settings. If you 841 updated and built after about 20070315, do "nbmake-$arch 842 cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a 843 rebuild of object files that might have been built 844 incorrectly, and ensure that you have at least 845 src/lib/libc/Makefile 1.130. 846 847 20070210: 848 src/sys/sys/{sa.h,savar.h} were removed. 849 find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \ 850 | xargs egrep -l '/sa.h|/savar.h' | xargs rm 851 will allow dependencies on those files to get get rebuilt 852 853 20070209: 854 The threading model was changed when the newlock2 branch 855 was merged to NetBSD-current. If you boot with a new 856 kernel (version 4.99.10), then you also need a new pthread 857 library (/usr/lib/libpthread.so.0.7). If you boot with 858 an old kernel, then you need the old pthread library 859 (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and 860 the pthread library in sync, old threaded applications should 861 continue to work with an old or new kernel. Note that named(8) 862 is the only threaded application in the base system. 863 864 20061214: 865 Following the move of string_to_flags() and flags_to_string() 866 from the bin/ls/ sources to libutil, users doing UPDATE builds 867 will need to do a "make cleandir" in 868 tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/, 869 bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/, 870 usr.bin/xinstall/, libexec/ftpd/, rescue/, as well 871 as the installation images in distrib/ 872 in order to excise stale references to the old stat_flags.h header 873 file in the ls sources -- stat_flags.h has been removed. 874 875 20061108: 876 The configure script used in the src/tools/gcc compiler has been 877 changed to indicate that our libc has ssp support built-in and 878 does not depend on -lssp and -lssp-nonshared. You'll need to 879 make clean in src/tools/gcc first to rebuild the compiler. 880 881 20061009: 882 The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer 883 available. Use net.inet{,6}.tcp{,6}.congctl.selected instead. 884 885 20060814: 886 The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been 887 withdrawn. Use vidcvideo and pckbd instead. See the GENERIC 888 kernel configuration for an example. X servers from the last 889 few years should cope. 890 891 20060703: 892 MPACPI is no more. We always configure PCI interrupts using ACPI 893 if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed 894 to ACPI_SCANPCI. Thanks to work from fvdl. 895 896 20060627: 897 socket(2) has changed, and its system call has been versioned. 898 For userlands with the old version of socket(2), make sure that 899 your kernel has 'options COMPAT_30' set, or else 'bad system call' 900 errors will result. 901 902 Hints for a more successful build: 903 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 904 Use build.sh, but do not use its "expert mode": 905 This will automatically build the tools in the 906 correct order, and it will keep the tools and the 907 new build products from interfering with the running 908 system. This will allow you to ignore most of the 909 other advice in this file. 910 Build a new kernel first: 911 This makes sure that any new system calls or features 912 expected by the new userland will be present. This 913 helps to avoid critical errors when upgrading. 914 Use object directories: 915 This helps to keep stale object 916 files from polluting the build if a Makefile "forgets" 917 about one. It also makes it easier to clean up after 918 a build. It's also necessary if you want to use the 919 same source tree for multiple machines. 920 To use object directories with build.sh: 921 a) invoke build.sh with the "-M" or "-O" options. 922 To use object directories without using build.sh: 923 a) cd /usr/src ; make cleandir 924 b) Add "OBJMACHINE=yes" to /etc/mk.conf 925 c) Add "MKOBJDIRS=yes" to /etc/mk.conf 926 d) cd /usr/src ; make build 927 Note that running "make obj" in a directory will create 928 in obj.$MACHINE directory. 929 Build to a DESTDIR: 930 This helps to keep old installed files (especially libraries) 931 from interfering with the new build. 932 To build to a DESTDIR with build.sh, use the "-D" option. 933 To build to a DESTDIR without using build.sh, set the DESTDIR 934 environment variable before running make build. It should be 935 set to the pathname of an initially empty directory. 936 Problems: if you do not use build.sh, you might need to 937 update critical utilities without using DESTDIR since 938 nothing is executed from what is installed in DESTDIR. 939 (See critical utils, below.) 940 Build often: 941 This keeps critical utilities current enough to not choke 942 on any other part of the source tree that depends on up to 943 date functionality. If you use build.sh, you should not have 944 this problem. 945 946 What to do if things don't work: 947 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 948 When things don't work there are usually a few things that commonly 949 should be done. 950 1) make includes 951 This should be done automatically by make build. 952 2) cd share/mk && make install 953 Again, automatically done by make build. 954 955 Failsafe rebuild of a small part of the tree: 956 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 957 To make sure you rebuild something correctly you want to do 958 something like the following: 959 1) Make sure the includes and .mk files are up to date. 960 2) Make sure any program used to build the particular 961 utility is up to date. (yacc, lex, etc...) 962 3) cd ...path/to/util... 963 make cleandir 964 rm ...all obj directories... 965 make cleandir # yes, again 966 make obj 967 make depend && make 968 969 Failsafe rebuild of the entire tree: 970 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 971 If you really want to make sure the source tree is clean and 972 ready for a build try the following. Note that sourcing /etc/mk.conf 973 (a make(1) Makefile) in this manner is not right, and will not work 974 for anyone who uses any make(1) features in /etc/mk.conf. 975 976 ---cut here--- 977 #!/bin/sh 978 . /etc/mk.conf 979 980 if [ -z $NETBSDSRCDIR ] ; then 981 NETBSDSRCDIR=/usr/src 982 fi 983 if [ \! -d $NETBSDSRCDIR ] ; then 984 echo Unable to find sources 985 exit 1 986 fi 987 find $NETBSDSRCDIR -name \*.o -o -name obj.\* -o -name obj -exec rm \{\} \; 988 989 if [ -z $BSDOBJDIR ] ; then 990 BSDOBJDIR=/usr/obj 991 fi 992 if [ -d $BSDOBJDIR ] ; then 993 rm -rf $BSDOBJDIR 994 fi 995 996 cd $NETBSDSRCDIR && make cleandir 997 998 ---cut here--- 999 1000 Critical utilities: 1001 ^^^^^^^^^^^^^^^^^^^ 1002 usr.bin/compile_et 1003 usr.bin/make 1004 usr.bin/yacc 1005 usr.bin/lex 1006 usr.bin/xlint 1007 usr.bin/config 1008 1009 Other problems and possible solutions: 1010 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 1011 Symptom:Complaints involving a Makefile. 1012 Fix: Rebuild usr.bin/make: 1013 cd usr.bin/make && make && make install 1014 Or, a failsafe method if that doesn't work: 1015 cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin 1016 1017 Fix: Make sure .mk files are up to date. 1018 cd share/mk && make install 1019 1020 Symptom:Kernel `config' fails to configure any kernel, including GENERIC. 1021 Fix: Rebuild usr.bin/config 1022 1023 Symptom: 1024 Fix: Rebuild usr.bin/yacc 1025 1026 Symptom: 1027 Fix: Rebuild usr.bin/lex 1028 1029 Symptom: 1030 Fix: rm /usr/lib/libbfd.a 1031 1032 Symptom:Obsolete intermediate files are used during compilation 1033 Fix: Try the following sequence of commands in the directory in question. 1034 make cleandir; rm `make print-objdir`; make cleandir; make obj 1035 (If you built the tree without "make obj" in the past, obsolete files 1036 may remain.
