UPDATING revision 1.347
1$NetBSD: UPDATING,v 1.347 2024/04/11 06:20:29 nia Exp $ 2 3This file (UPDATING) is intended to be a brief reference to recent 4changes that might cause problems in the build process, and a guide for 5what to do if something doesn't work. 6 7For a more detailed description of the recommended way to build NetBSD 8using build.sh, see the BUILDING file. 9 10Note that much of the advice in this UPDATING file was written before 11build.sh existed. Nevertheless, the advice here may be useful for 12working around specific problems with build.sh. 13 14Sections are marked with "^^^^^". After the section on "Recent changes" 15are several sections containing more general information. 16 17See also: BUILDING, build.sh, Makefile. 18 19Recent changes: 20^^^^^^^^^^^^^^^ 21 2220240410: 23 Update builds may require manually deleting 24 $DESTDIR/var/run/named (and, potentially, 25 $DESTDIR/var/run/lwresd) in order to avoid checkflist failure. 26 2720240409: 28 32-bit compatibility libraries were moved into the base32 29 and debug32 sets. HTML man pages were moved into the manhtml set. 30 3120230828: 32 If: 33 - you updated to current and ran postinstall between 20230826 34 and 20230828 inclusive, and 35 - you are not using anything outside the base system to 36 populate /etc/openssl/certs (e.g., manually adding 37 certificates or using ca-certificates or mozilla-rootcerts or 38 mozilla-rootcerts-openssl from pkgsrc), 39 delete /etc/openssl/certs and rerun postinstall or just 40 `certctl rehash'. 41 42 Otherwise, certctl(8) will think someone else has left 43 /etc/openssl/certs in the way and will avoid clobbering it on 44 upgrade from older NetBSD. 45 4620230718: 47 build.sh will use mk.conf in the same directory as build.sh instead 48 of /etc/mk.conf, unless MAKECONF is already defined in the environment. 49 5020230714: 51 Import of gcc 10.5 requires a clean build of at least tools/gcc 52 and external/gpl3/gcc* object directories. An update build 53 without cleaning will result in obscure failures in rare corner 54 cases. 55 5620230604: 57 Building native kernels with the installed make(1) instead of 58 the $TOOLDIR/bin/nbmake-${arch} wrapper will fail if userland 59 has not been updated. Note that this is an unsupported build 60 configuration (but usually works if userland is -current enough). 61 6220230523: 63 ctfmerge was fixed as macOS host tool. This may require a clean tools 64 rebuild to detect the update to tools/compat/configure. 65 6620230515: 67 New openssl build requires removal of the crypto/external/bsd/openssl 68 and tests/crypto/libcrypto subdirectories in the ${OBJDIR} hierarchy. 69 Otherwise test results may be wrong due to wrong "golden" output 70 files being installed. 71 7220230322: 73 Fixes for moved /lib/libisns* mean that builds will complain about 74 ./usr/lib/libisns* being missing until src/lib/libisns is forced 75 to (re)install the files, including the symlinks. The simplest 76 way is to clean this subdir before building. 77 7820230112: 79 New binutils require an updated ld.elf_so. If you are doing 80 (unsupported) in-place self builds (with the -E flag to build.sh), 81 make sure to have installed latest ld.elf_so before you rebuild 82 userland. 83 8420221116: 85 The addition to NetBSD's version of UFS2 of support for extended 86 attributes broke backward compatibility with previous releases 87 of NetBSD, so UFS2 has been restored to being compatible with 88 previous NetBSD releases by disabling extended attributes. 89 (Note that ACLs are implemented as extended attributes, so 90 this changes disables ACLs as well.) 91 92 Support for UFS2 with extended attributes is now available in a new 93 UFS variant called UFS2ea. If you have created extended attributes 94 in an original UFS2 file system then "fsck -p" will now fail due to 95 the unexpected presence of extended attributes and "fsck -y" will 96 remove all extended attributes. If you wish to preserve extended 97 attributes rather than delete them, there is a utility to convert 98 a UFS2 file system to UFS2ea and leave extended attributes in place, 99 but this should be used with caution since it will preserve any 100 extended attributes that have been corrupted by the backward 101 incompatibility too. 102 103 If you wish to use a UFS2ea file system as your root file system, 104 then you will need to update your boot loader to a version that 105 supports UFS2ea. 106 107 For more information, see: 108 https://wiki.netbsd.org/features/UFS2ea 109 11020221111: 111 The new libdrm import worsened the conflict issues for the 112 kdump/ktruss ioctl, and i915 now conflicts with base, and has 113 been turned off. This will cause update build issues like: 114 115 kdump-ioctl.c:12175:143: error: 'DRM_IOCTL_I915_DESTROY_HEAP' 116 undeclared here (not in a function); 117 did you mean 'DRM_IOCTL_MODE_DESTROY_DUMB'? 118 119 You'll need to clean usr.bin/ktruss, usr.bin/kdump, and rescue. 120 12120220921: 122 Since the kernel version was bumped to 9.99.100, the bootloader 123 must be updated on x86 or EFI boot platforms in order to load 124 modules from boot.cfg(5) or interactively at the bootloader 125 prompt. 126 127 The kernel can still load modules at runtime, with modload(8) 128 or modules.conf(5), with no bootloader update. This will not 129 affect release branches because it only applies to patch 130 numbers >=100. 131 132 On x86 (i386 or amd64) with BIOS boot, this requires copying a 133 new /usr/mdec/boot to /boot. You can build this in the destdir 134 by running `$TOOLDIR/bin/nbmake-$ARCH dependall install' in 135 sys/arch/i386/stand. 136 137 On platforms with EFI boot (including x86 with EFI boot), this 138 requires copying a new /usr/mdec/boot*.efi to the EFI/BOOT/ 139 directory on the EFI system partition. The boot*.efi file is: 140 141 aarch64 bootaa64.efi 142 amd64 bootx64.efi 143 arm bootarm.efi (32-bit arm) 144 i386 bootx32.efi 145 146 You can build this in the destdir by running 147 `$TOOLDIR/bin/nbmake-$ARCH dependall install' in 148 sys/stand/efiboot/boot*. 149 15020220821: 151 Support for building extsrc/ has been deprecated. 152 EXTSRCSRCDIR and MKEXTSRC have been deprecated. 153 15420220714: 155 Updates to xorg-server and associated drivers may cause builds to 156 fail. Cleaning both DESTDIR and the xorg build tree may be needed. 157 15820220628: 159 Changes in the build of src/games/robots require a clean build 160 of that program. 161 16220211116: 163 Changes in the xorg build require clean obj dirs for external/mit/xorg 164 (or a full clean/non-update build). 165 16620211112: 167 Device tree sources were updated for evbarm. Some device nodes 168 (in particular, ld(4) devices on the ROCKPro64) will be renumbered. 169 17020211014: 171 MKPIE default for aarch64 has changed, a clean build is required. 172 17320210917: 174 Changed MNT_ACLS to default to POSIX1e ACLs instead of NFSv4 175 ACLs, to be compatible with FreeBSD. If you are using NFSv4 ACLs 176 and have "acls" in /etc/fstab you'll need to change it to "nfs4acls". 177 17820210711: 179 Updated GMP sources may require cleaning in tools/gmp and/or in 180 external/lgpl3/gmp/lib, particularly if GCC itself does not build. 181 18220210417: 183 GCC 10 was enabled for several platforms. If builds fail in either 184 tools/gcc or external/gpl/gcc, first try cleaning those objects and 185 removing the $DESTDIR/usr/include/g++ subdirectory. 186 18720201230: 188 lint1/ops.c is no longer autogenerated. If this makes the build 189 fail, clean $OBJDIR/tools/*lint* and $OBJDIR/usr.bin/*xlint*. 190 19120201016: 192 MIPS kernel modules have been disabled until they work. This will 193 turn up in extra files in the DESTDIR, which should be cleaned. 194 19520200925: 196 GNU MPC and MPFR have been updated. At least MPFR needs cleaning 197 in both the tools and external dirs. 198 19920200912: 200 GCC 9 has arrived for Arm and x86 platforms, and will be coming 201 for several more, as will binutils 2.34. Clean as required. 202 20320200907: 204 GCC 9 is coming, and binutils has been updated for MIPS. This 205 probably requires cleaning the tools/binutils. 206 20720200811: 208 GCC updates may require cleaning the objdir. This may occur 209 due to GCC 7.5 update, GCC 8.4 move to gcc.old, or the upcoming 210 GCC 9 upgrade. 211 21220200614: 213 blacklist* has been renamed to blocklist*. postinstall(8) 214 should handle the migration. 215 21620200601: 217 Due to a mistake in LIBISPRIVATE handling, .so libraries were 218 created in the build directories and need cleaning. 219 22020200311: 221 GCC 8 ports will need cleaning in src/tools/gcc and 222 src/external/gpl3/gcc due to GCC 8.4 update. 223 22420191118: 225 More architectures were switched to gcc8: 226 i386, ia64 powerpc64, sparc, sparc64, arm 227 The same comments as in 20191022 apply. 228 22920191112: 230 The LLVM update requires a clean rebuild for all architectures using 231 LLVM during the tools build phase (i386, amd64, aarch64). 232 23320191022: 234 Ports amd64 and aarch64 switched to GCC 8.3 by default. 235 In-place ("expert mode", build.sh -E) builds are not supported 236 when going from a GCC 7 userland to GCC 8. Do a regular 237 build to a different DESTDIR (or preferably: build.sh -U) at least 238 once and install sets, or download comp.{tar.xz,tgz} from the 239 daily builds and install that before doing the next in-place build. 240 24120191001: 242 GCC 8.3 was imported. Builds of src/tools/gcc may fail if 243 old builds with GCC 7 output now uses GCC 8. Clean this 244 directory, and also clean src/external/gpl3/gcc. 245 24620190903: 247 Files with names that coincide with existing files' names on 248 case-insensitive file systems were inadvertently committed, for 249 radeon GPU firmware. We cannot mark these as obsolete for 250 postinstall to fix, so if you updated src since 2019-08-26, and 251 ran build.sh distribution or ran build.sh release, you must 252 manually delete the following files in your DESTDIR (which is 253 usually $OBJDIR/destir.$ARCH), or from / if you have installed 254 them: 255 256 /libdata/firmware/radeon/bonaire_ce.bin 257 /libdata/firmware/radeon/bonaire_mc.bin 258 /libdata/firmware/radeon/bonaire_me.bin 259 /libdata/firmware/radeon/bonaire_mec.bin 260 /libdata/firmware/radeon/bonaire_pfp.bin 261 /libdata/firmware/radeon/bonaire_rlc.bin 262 /libdata/firmware/radeon/bonaire_sdma.bin 263 /libdata/firmware/radeon/bonaire_smc.bin 264 /libdata/firmware/radeon/bonaire_uvd.bin 265 /libdata/firmware/radeon/hainan_ce.bin 266 /libdata/firmware/radeon/hainan_mc.bin 267 /libdata/firmware/radeon/hainan_me.bin 268 /libdata/firmware/radeon/hainan_pfp.bin 269 /libdata/firmware/radeon/hainan_rlc.bin 270 /libdata/firmware/radeon/hainan_smc.bin 271 /libdata/firmware/radeon/hawaii_ce.bin 272 /libdata/firmware/radeon/hawaii_mc.bin 273 /libdata/firmware/radeon/hawaii_me.bin 274 /libdata/firmware/radeon/hawaii_mec.bin 275 /libdata/firmware/radeon/hawaii_pfp.bin 276 /libdata/firmware/radeon/hawaii_rlc.bin 277 /libdata/firmware/radeon/hawaii_sdma.bin 278 /libdata/firmware/radeon/hawaii_smc.bin 279 /libdata/firmware/radeon/kabini_ce.bin 280 /libdata/firmware/radeon/kabini_me.bin 281 /libdata/firmware/radeon/kabini_mec.bin 282 /libdata/firmware/radeon/kabini_pfp.bin 283 /libdata/firmware/radeon/kabini_rlc.bin 284 /libdata/firmware/radeon/kabini_sdma.bin 285 /libdata/firmware/radeon/kaveri_ce.bin 286 /libdata/firmware/radeon/kaveri_me.bin 287 /libdata/firmware/radeon/kaveri_mec.bin 288 /libdata/firmware/radeon/kaveri_mec2.bin 289 /libdata/firmware/radeon/kaveri_pfp.bin 290 /libdata/firmware/radeon/kaveri_rlc.bin 291 /libdata/firmware/radeon/kaveri_sdma.bin 292 /libdata/firmware/radeon/mullins_ce.bin 293 /libdata/firmware/radeon/mullins_me.bin 294 /libdata/firmware/radeon/mullins_mec.bin 295 /libdata/firmware/radeon/mullins_pfp.bin 296 /libdata/firmware/radeon/mullins_rlc.bin 297 /libdata/firmware/radeon/mullins_sdma.bin 298 /libdata/firmware/radeon/oland_ce.bin 299 /libdata/firmware/radeon/oland_mc.bin 300 /libdata/firmware/radeon/oland_me.bin 301 /libdata/firmware/radeon/oland_pfp.bin 302 /libdata/firmware/radeon/oland_rlc.bin 303 /libdata/firmware/radeon/oland_smc.bin 304 /libdata/firmware/radeon/pitcairn_ce.bin 305 /libdata/firmware/radeon/pitcairn_mc.bin 306 /libdata/firmware/radeon/pitcairn_me.bin 307 /libdata/firmware/radeon/pitcairn_pfp.bin 308 /libdata/firmware/radeon/pitcairn_rlc.bin 309 /libdata/firmware/radeon/pitcairn_smc.bin 310 /libdata/firmware/radeon/tahiti_ce.bin 311 /libdata/firmware/radeon/tahiti_mc.bin 312 /libdata/firmware/radeon/tahiti_me.bin 313 /libdata/firmware/radeon/tahiti_pfp.bin 314 /libdata/firmware/radeon/tahiti_rlc.bin 315 /libdata/firmware/radeon/tahiti_smc.bin 316 /libdata/firmware/radeon/verde_ce.bin 317 /libdata/firmware/radeon/verde_mc.bin 318 /libdata/firmware/radeon/verde_me.bin 319 /libdata/firmware/radeon/verde_pfp.bin 320 /libdata/firmware/radeon/verde_rlc.bin 321 /libdata/firmware/radeon/verde_smc.bin 322 323 We will re-import these radeon firmware images another way 324 later. 325 32620190727: 327 The uefi bootloader has gained tftp support and needs a clean 328 build. If you do update builds, manually clean its object 329 directory by something like: 330 cd sys/arch/i386/stand/efiboot && make clean 331 33220190723: 333 The jemalloc allocator in libc is now built without extended 334 debugging (for performance reasons). In update builds make sure 335 to rebuild it completely, by removing all affected object files, 336 including compat builds, something like: 337 cd /usr/obj && find . -type d -name jemalloc|xargs rm -rf 338 33920190207: 340 GCC 7 switched for many ports. Update builds are likely to fail. 341 34220180924: 343 A newer OpenSSL version has been imported. If you are doing 344 update builds, make sure to remove all old obj dirs, like: 345 cd /usr/obj && find . -type d -name openssl | xargs rm -rf 346 34720180717: 348 On aarch64 int64_t and related types have changed from long long 349 to long. This requires recompiling all C++ binaries. 350 35120180713: 352 On amd64 and i386 static binaries are now build position 353 independent. This requires recompilation of all object 354 files used to create the crunched /rescue binary. 355 Clean the rescue directory in your obj directory before 356 doing an update build, otherwise linking will fail. 357 35820180414: 359 Existing binutils was migrated to binutils.old. Manual 360 removal of tools/binutils objects directory may be required 361 to fix tools build failure. 362 36320180311: 364 bdftopcf was updated and may need cleaning in the 365 src/external/mit/xorg/tools/bdftopcf subdirectory if there are 366 link errors. 367 36820180212: 369 between OpenSSL and GCC updates, many things may fail to build. 370 any failure that looks like GCC or openssl is best handled by 371 a clean destdir and objdir. Full cleandir and destdir deletion 372 is recommended if build failures occur. 373 37420171225: 375 removal of the vadvise syscall requires manual removal of all 376 associated files from the libc build object directory (including 377 the .depend files) - a command like: 378 cd $OBJ && find . -type d -name libc | xargs rm -rf 379 For architectures that support multiple "compat" binary targets, 380 you'll need to cleanup both the regular libc directory and the 381 compat ones (the above command will do that). 382 38320171010: 384 a change to the build structure of external/bsd/acpica/bin/iasl 385 means that its objdir (or *.d and .depend at least) might need 386 to be manually removed - or a build done once without -u. 387 38820170822: 389 a new version of GMP has been imported and probably 390 will break parts of builds related to themselves or GCC, both 391 in the tools and the native section. Remove all GCC, GMP, MPFR 392 and MPC objdirs or build once without -u. 393 39420170816: 395 a new version of MPFR and MPC have been imported and probably 396 will break parts of builds related to themselves or GCC, both 397 in the tools and the native section. Remove all GCC, GMP, MPFR 398 and MPC objdirs or build once without -u. 399 40020170402: 401 a new version of dhcpcd has been imported, which does not support 402 update builds from the previous version. Remove your 403 external/bsd/dhcpcd object dir or build once without -u. 404 40520170211: 406 a new terminfo database has been imported. 407 The structure of it has changed slightly from prior versions and 408 an updated tic tool is required. 409 If you build.sh, don't use -u 410 41120170207: 412 various arch dependent libc/exect.S files were removed 413 Either remove the obj directories (lib/libc and compat/amd64/i386/lib 414 if it exists) or do a clean build. 415 (This is a bug in the make system, it should be corrected without 416 human intervention, but isn't.) 417 41820170104: 419 xinput build options have changed. 420 Remove the obj directory (external/mit/xorg/bin/xinput) 421 if you build.sh -u 422 42320170103: 424 a new version of flex has been imported. 425 Remove the file from obj (external/bsd/flex) 426 if you build.sh -u 427 42820161014: 429 a new version of OpenSSL has been imported. 430 Remove the files from obj (crypto/external/bsd/openssl) 431 if you build.sh -u 432 43320161009: 434 a new version of dhcpcd has been imported with slightly changed 435 build infrastructure. When doing a build.sh -u this requires 436 pruning the external/bsd/dhcpcd objdir. 437 43820160914: 439 i386, amd64, shark, ofppc and macppc have joined shark and x68k 440 ports in using xorg-server 1.18. This requires a clean destdir 441 and a clean objdir. 442 44320160527: 444 i386 needs a full cleandir or objdir deletion because PIE has 445 been enabled. (see the amd64 entry two down for further info) 446 44720160418: 448 libedit needs manual removal of all autogenerated files since 449 some of them are not autogenerated anymore. Remember that there 450 might be two copies of libedit if your platform builds "compat". 451 45220160410: 453 amd64 needs full "make cleandir" or deletion of objdir now that 454 PIE has been enabled for amd64. PIE, or position-independent 455 executables, means all code, including executables and not just 456 shared libraries, is position-independent and hence able to be 457 relocated by ASLR, address space layout randomization. 458 459 The change was made in Makefile variables for compiler and 460 linker flags, for which make(1) does not record dependencies, 461 hence it is unable to detect that all .o files need rebuilding. 462 463 Partial rebuilds with some modified source files will likely 464 fail when linking executables, since the linker refuses to mix 465 position-independent code with position-dependent code in 466 position-independent executables: 467 468 .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC 469 47020160401: 471 Ports switching to GCC 5.3 will need a full "make cleandir". 472 Some people have found that cleandir is not sufficient, so if 473 in doubt delete the entire object directory tree for gcc. 474 47520160306: 476 NetBSD's regexp implementation is now part of libnbcompat. 477 Nblex, nbm4, nbpax, nbsed use it and they may crash on 478 non-NetBSD hosts if linked with stale object files produced 479 while they included a non-NetBSD regex.h. 480 In any case, you should "make cleandir" at least these tools 481 before updating your toolchain. 482 48320160125: 484 Dtrace has been enabled by default on some architectures. 485 When doing an update build, make sure to clean the etc/mtree 486 object directory before starting the build - otherwise the 487 needed directories in destdir will not be created. 488 An easy way to do this is: 489 cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir 490 49120150818: 492 New acpica requires "make cleandir" in src/external/bsd/acpica 493 again. 494 49520150413: 496 New acpica requires "make cleandir" and reinstalling yacc 497 in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and 498 also "make cleandir" in /usr/src/external/bsd/acpica. 499 50020150404: 501 Lint changes require a full rebuild of the tool, so make 502 sure to build without -u option to build.sh, or manually 503 do a make cleandir in src/tools/lint1 and 504 src/usr.bin/xlint. 505 50620150310: 507 Improvements to openssl for arm mean that update builds of 508 the openssl libraries will fail. A make cleandir in 509 external/bsd/openssl/lib is needed 510 51120141026: 512 A mishap during the import of pppd may cause your corruption 513 in your cvs directory if you happened to do a cvs update 514 during a short period of time. To fix, just remove the 515 directory src/external/bsd/ppp/dist/pppd completely 516 and let cvs restore it on next update. 517 51820140721: 519 The src/external/mit/lua/src directory was accidentally created 520 and then deleted in the CVS repository. If you get errors like 521 522 cvs [update aborted]: cannot open directory 523 /cvsroot/src/external/mit/lua/src: No such file or directory 524 525 then delete your local copy of that directory tree and try again. 526 52720140530: 528 ARM eABI switched to DWARF based exception handling. This requires 529 rebuilding all C++ code. It is strongly advised to do a clean build. 530 53120140131: 532 The new compiler_rt/libc integration moved a few things. It is strongly 533 advised to do a clean build. At least lib/libc, the compat version(s) 534 of libc, libkern, rump and the kernels need to be cleaned. 535 53620131227: 537 1. The new ntpd runs in a restricted mode to prevent amplification 538 attacks. If you need ntpdc to work you need to explicitly enable 539 mode7 in your config file. Make sure you put the necessary restrict 540 statements to avoid being exposed. 541 2. strncat has moved from lib/libc to common/lib/libc; you might need 542 to make clean in libc 543 54420131129: 545 The GMP sources were updated, and builds will likely fail without 546 cleaning their build trees for both tools and in-tree, like below. 547 54820131128: 549 The MPC and MPFR sources were updated, and builds may require their 550 tools and in-tree directories cleaned for successful updates. 551 55220130605: 553 The kernel option FAST_IPSEC no longer exists, it's been renamed 554 to IPSEC (and the older IPSEC version removed). 555 55620130605: 557 Previous freetype installations erroneously installed private 558 header files. If you are building against a non-empty $DESTDIR, 559 please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/. 560 56120130531: 562 The xdm update may cause build failure due to xdm.man being 563 in the obj tree. Make sure to ensure any like this: 564 nbmake: nbmake: don't know how to make xdm.man. Stop 565 is fixed by deleting the xdm.man in the obj tree. 566 56720130530: 568 Updates of many xsrc packages will leave old .pc files around. 569 Best to clean out the xsrc objdir entirely before rebuilds. 570 57120130301: 572 The removal of netiso requires manual removal of /usr/include/netiso 573 prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump} 574 57520120726: 576 The update of OpenSSL requires cleaning both the OpenSSL build 577 directory and DESTDIR. *Even non-update builds require cleaning 578 DESTDIR.* Builds done without taking these steps may fail, or in 579 some cases may succeed and install broken OpenSSL libraries that 580 cause third-party software to link incorrectly and/or crash. 581 58220120507: 583 The database schema for makemandb was changed. You will 584 need to update the database using 'makemandb -f' or wait 585 for the next weekly run to fix it. 586 58720120319: 588 sys/conf/Makefile.kern.inc has been modified to adjust the 589 size of db_symtab automatically. You need to update dbsym in 590 your $TOOLDIR to build kernels with options SYMTAB_SPACE. If 591 you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your 592 mk.conf. 593 59420120216: 595 Default for MKCATPAGES changed to NO. Update builds will fail 596 unless DESTDIR is cleaned manually. If you built between 20120207 597 and 20120216, daily and weekly could have created an unreadable 598 /var/db/man.db index for apropos. Running makemandb -f or 599 the next run of weekly will fix it. 600 60120111227: 602 If you built between 20111225 and 20111227 you need to remove 603 /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the 604 bump has been reverted. 605 60620111125: 607 The "rnd" pseudodevice has been added to sys/conf/std, which 608 means it should no longer be explicitly listed in kernel 609 configuration files. The line "pseudo-device rnd" should be 610 removed from any custom kernel config files users may have. 611 61220111119: 613 A problem with the datastructures used by the rndctl(8) 614 utility (pointers in datastructures in an array, making 32->64 615 bit compatibility very painful) has been fixed in a 616 non-backwards-compatible way. If you replace your kernel, 617 replace your rndctl executable too. 618 61920111001: 620 the prop_*_send_syscall() functions from proplib(3) have been 621 changed and their new version is not backward compatible with the old 622 one. So ensure that all consumers of these functions (currently: 623 quota2 code and its tests) are updated together with the new lib. 624 62520110817: 626 sparc has been changed to use GCC 4.5.3, so any objdir or 627 DESTDIR for them should be deleted before updating. 628 62920110806: 630 i386 and amd64 have been changed to use GCC 4.5.3, so any 631 objdir or DESTDIR for them should be deleted before updating. 632 63320110805: 634 The update to GCC 4.5.3 requires a non-trivial portion of 635 the tree to be cleaned. Best to delete both objdir and 636 DESTDIR before running this update. So far, only the 637 sparc64, mips and powerpc platforms have changed. 638 63920110803: 640 The layout of external/public-domain/xz has changed. To do an 641 update build you will have to remove the contents of the OBJDIR 642 for external/public-domain/xz/bin by hand as the xz entry there 643 is now a directory. 644 64520110410: 646 The configuration of src/tools/gcc has changed. To do an 647 update build you have to clean both tools/binutils and 648 tools/gcc by hand. 649 65020110328: 651 Building the Xorg binary was moved into a subdirectory to fix 652 ordering issues with "make all". It may be necessary to remove 653 the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86 654 if your update build fails, as the "Xorg" entry there is now a 655 directory. 656 65720110121: 658 Assembler files no longer use -traditional-cpp. This can break 659 the build of individual parts of the tree. This is handled 660 correctly by build.sh. Manual builds have to update /usr/share/mk 661 and re-run config(1) for any kernel configurations as needed. 662 66320101217: 664 The tcpdump(8) program was changed to drop privileges and chroot(2) 665 by default. It may be necessary to manually update passwd(5) and 666 group(5) in order to make the program work with existing setups. 667 66820101125: 669 The latest changes to setenv(3) disallow setting environment 670 variables with names that contain '='. Revision 1.18 of env.c 671 assumed that this was allowed. Installing a new libc with an 672 old copy of /usr/bin/env causes env x=1 printenv | grep x= to 673 break which affects the autoconf tests for dependency finding, 674 so building gcc will end up printing: 675 checking dependency style of gcc... none 676 configure: error: no usable dependency style found 677 Fix it by rebuilding and re-installing env. 678 67920101119: 680 Recent Xorg updates in xsrc/external/mit/ may cause various build 681 or run-time problems. Delete your entire DESTDIR and OBJDIR if you 682 have any build problems with xsrc, or problems with mismatched 683 versions between xorg-server and drivers. 684 68520100604: 686 The update of ATF to 0.9 causes old tests written in shell to fail 687 unless they are rebuilt. If you are building with MKUPDATE=yes, 688 you need to clean the src/external/bsd/atf/tests/ and the src/tests/ 689 trees by hand. 690 69120100522: 692 Recent Xorg updates in xsrc/external/mit/ will cause various build 693 problems. Delete your entire DESTDIR and OBJDIR if you have any 694 build problems with xsrc. 695 69620100522: 697 private section of <ctype.h> was split, and now mklocale(1) 698 include ctype_local.h, so you have to make cleandir in tools/mklocale. 699 70020100520: 701 The location of the xkb compiled descriptions has changed. Please 702 remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR. 703 70420100222: 705 The shared objects file extension has been changed from .so to 706 .pico, in order to avoid conflicts with shared libraries names 707 libXX.so. All now stale regular .so files can be removed from 708 your object directories. 709 71020100204: 711 The termcap database has been removed from the sources, 712 but has not been marked obsolete so it is not removed 713 from the system when upgrading. 714 As such, you will need to remove them from your object 715 and destination directories. 716 71720091101: 718 After updating, it may be necessary to make the 'cleandir' 719 target in src/tools/yacc/ and in src/usr.bin/yacc/ before a 720 'build.sh -u tools' or 'build.sh -u distribution'. Ditto 721 src/tools/lex/ and src/usr.bin/lex/. 722 72320091001: 724 On amd64 you must rebuild tools (to get the new binutils) 725 before building a kernel, or the build fails on cpufunc.S. 726 72720091001: 728 An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb 729 symlink, failing the build. Delete the link, and the subdir 730 it is in, and retry your build. 731 73220090718: 733 libc build changed so that strchr() provides the extra entry 734 point for index(). Update build of libc.a (and libc_pic.a) 735 may fail because the archive contains the unwanted index.o. 736 (Similarly for strrchr() and rindex().) 737 73820090709: 739 Native Xorg was upgraded again. Builds will probably fail again 740 without a clean objdir, at least for src/external/mit/xorg. 741 74220090616: 743 Native Xorg was upgraded. Builds will need a clean objdir for 744 src/external/mit/xorg. Upgrading a system from sets will not 745 work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc 746 subdirectory has been changed into a file, and this needs to 747 be manually "rm -r"'ed before installing xbase.tgz. 748 74920090501: 750 Several new functions were added to string.h/libc, and this 751 can cause autoconf problems during the tool build for people 752 who fail to clean out their tools objects properly. If you 753 note messages about stpcpy, stpncpy or strnlen accompanying a 754 failure during the tool build, clean out all your tools 755 objects and start again. 756 75720090325: 758 The i386 port was switched to i486 default toolchain. This requires 759 cleaning your src/tools directory and $TOOLDIR and rebuilding them. 760 76120090126: 762 The __posix_fadvise50 system call changed assembly stub type. You 763 need to 'rm -f __posix_fadvise50.*' in the libc build directory 764 to avoid using the old assembly stub. 765 76620090202: 767 pkg_install now depends on the pkgdb cache for automatic conflict 768 detection. It is recommended to rebuild the cache with 769 ``pkg_admin rebuild''. 770 77120090110: 772 time_t and dev_t have been bumped to 64 bit quantities. To upgrade: 773 1. Make sure your kernel has COMPAT_50 in it. Build and install. 774 This is needed even in the MODULAR kernel because there is 775 conditionally compiled code in rtsock.c. 776 2. make sure build.sh completes and the binaries in a chroot work 777 before installing. 778 3. If you don't use build.sh and you build directly to root, and 779 your build breaks in the middle, don't despair. Make sure headers 780 are installed properly, and start building libraries first libc 781 and libutil, install them and then continue building all the 782 libraries in src/lib and src/gnu/lib and install them. Once 783 the new libraries are installed, you can restart the build. 784 4. If you compile packages and you notice link time warnings, 785 rebuild the required packages to update their shared libraries. 786 Any package you rebuild will require rebuilding all the packages 787 that depend on it. 788 5. Next time you run pwd_mkdb with the new binary, the file 789 will be upgraded and it will not be backwards compatible. 790 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see 791 lastlogx(5)) have been versioned, and there is a heuristic 792 for utmp. You are better off removing the old files after 793 upgrading. The automated clearing of /var/run during 794 boot, and the automated rotating of files in /var/log by 795 newsyslog(8), may mean that you do not have to remove the 796 files manually. 797 7. The optional accounting file (/var/account/acct, see 798 accton(8)) has not been versioned, and will need to be 799 removed. The automatic rotation of the accounting file by 800 /etc/daily limits the bad consequences of failure to remove 801 the file. 802 8. Application software that writes time_t to binary files on 803 disk will break or need attention. Most notably: if you are 804 using PostgreSQL < 8.4, you need to dump your databases, 805 rebuild PostgreSQL with the new time_t, then restore. 806 80720081219: 808 config(1) has been updated, and one of the files it creates - 809 swapnetbsd.o - has changed format. You need to rebuild config 810 (done automatically by build.sh) and then you need to rerun 811 config on all kernel configuration files before rebuilding those 812 kernels. 813 81420081205: 815 If you build with MKX11=no, you should remove /etc/rc.d/xdm and 816 /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc 817 set and will appear as extra files for MKX11=no update builds. 818 81920081122: 820 On i386, various kernel options(4) in GENERIC including 821 file systems have been disabled and moved into kernel modules. 822 Before trying a new GENERIC kernel, you have to prepare the 823 following files as well as a new GENERIC kernel: 824 825 - build and install kernel modules from src/sys/modules 826 827 - install the latest bootloader, which will load a module 828 for the file system from which the kernel is loaded automatically 829 830 If you have to load your kernel from a file system which is not of 831 the same type as the root file system, you have to load the necessary 832 file system module manually on the boot prompt or in the boot.cfg file. 833 83420080827: 835 If you built and installed a libc from sources between 836 2008/08/20 and 2008/08/26 you got a broken strtouq(3) 837 which results in false errors reported by lint(1). 838 Since this breaks the libc build itself, manual help is 839 needed -- lint must be disabled temporarily, e.g.: 840 $ (cd lib/libc && make MKLINT=no dependall install) 841 84220080813: 843 MKDEBUG build was broken because the .depend files did not know 844 about .go files. You need to remove all .depend files and rebuild. 845 84620080802: 847 A regression in binary compatibility for pthread_mutex_t has 848 been fixed. Unfortunately, the price is breaking compatibility 849 for -current. 850 851 Threaded programs (using libpthread) and C++ programs (using 852 libstdc++) compiled after 20070907 and before 20080802 need to 853 be recompiled. 854 855 One way to find affected pkgsrc packages: 856 857 $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO 858 $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO 859 86020080731: 861 WAPBL (metadata journaling support) has been added, but at this 862 time isn't backwards compatible with pre-WAPBL aware kernels 863 and userland (fsck_ffs in particular). Please make sure you 864 don't use a journaled filesystem with an older kernel/userland, 865 especially an uncleanly mounted journaled filesystem. WAPBL 866 also requires the super block to be in the UFS2 format. You 867 can use fsck_ffs -c 4 to update the superblock format. 868 86920080721: 870 Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR 871 isn't defined. 872 87320080531: 874 The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed 875 from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8) 876 utility needs to be rebuilt and reinstalled as older binaries 877 won't work correctly. The following sequence of commands: 878 879 $ (cd sys/sys/ && nbmake-$arch includes) 880 $ (cd sbin/drvctl/ && nbmake-$arch clean) 881 $ (cd sbin/drvctl/ && nbmake-$arch all) 882 883 leaves new drvctl utility in sbin/drvctl build directory. 884 88520080503: 886 The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE. 887 88820080521: 889 For a while, unprivileged UPDATE builds would fail to 890 succeed at the checkflist stage, complaining that 891 ${DESTDIR}/stand/<arch>/ did not exist. A fix for this 892 problem was committed to share/mk/bsd.kmodule.mk, revision 1.9. 893 If you already hit this problem, update the .mk file, 894 remove ${DESTDIR}/stand/<arch>, and re-run the build. 895 89620080303: 897 Linker warnings are now fatal if $WARNS>0. 898 89920080126: 900 The posix_fadvise system call has been changed from an assembly 901 stub, to a c file that calls an assembly stub. You need to 902 'rm -f posix_fadvise.* .depend' in the libc build directory to 903 avoid using the old assembly stub. 904 90520071209: 906 The acpiec(4) driver has been split into two attachments. If you 907 get ACPI errors before the attachment, please update your kernel 908 configuration file appropriately or see GENERIC for more details. 909 91020071115: 911 The it(4) driver has been renamed to itesio(4) and the old port 912 argument specified in the kernel configuration file is not valid 913 anymore. The itesio(4) driver now uses the Super I/O address port 914 rather than the EC address port. Please update your kernel 915 configuration file appropriately or see GENERIC for more details. 916 91720071028: 918 The pccons(4) driver has been removed from the NetBSD/shark port. 919 You need to update any custom kernel configuration file you have 920 to remove any references to pccons (which includes removing the 921 now useless XSERVER option) and replace them with the correct 922 entries for the wscons driver. See the GENERIC configuration file 923 for more details. 924 92520070913: 926 A latent bug in dhclient/dhcpd that caused it to be unable to 927 enumerate interfaces was fixed. The bug began to cause 928 problems after 20070911 when the kernel's SIOCGIFCONF 929 implementation was repaired. From 20070529 to 20070911 racoon 930 could not enumerate interfaces. (These are noted because 931 normal kernel/userspace version matching hygiene is not 932 sufficient to avoid this problem.) Ensure that both kernel 933 and userland are from after 20070913. 934 93520070703: 936 nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It 937 calls the target-specific strip program, and the logic to pass 938 down STRIP from make has been removed. This requires a 939 re-installation of tools. 940 94120070422: 942 The way OS emulations lookup filenames inside the emulation root 943 has been changed. Rather than modify the pathname (and copy back 944 to userspace) namei() and lookup() directly check the emulation 945 root. One side effect is that absolute symlinks inside the emulated 946 root file system will be relative to that file system - unless they 947 start /../ this is useful when the emulated root is a real install 948 that has such links. 949 This might affect symlinks that have been added to reference outside 950 the emulated root. 951 95220070412: 953 The pckbc driver on sgimips IP32 has been removed. Use macekbc 954 instead. See the GENERIC32_IP3x kernel configuration for an 955 example. 956 95720070319: 958 src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so 959 on many platforms due to incorrect flags settings. If you 960 updated and built after about 20070315, do "nbmake-$arch 961 cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a 962 rebuild of object files that might have been built 963 incorrectly, and ensure that you have at least 964 src/lib/libc/Makefile 1.130. 965 96620070210: 967 src/sys/sys/{sa.h,savar.h} were removed. 968 find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \ 969 | xargs egrep -l '/sa.h|/savar.h' | xargs rm 970 will allow dependencies on those files to get get rebuilt 971 97220070209: 973 The threading model was changed when the newlock2 branch 974 was merged to NetBSD-current. If you boot with a new 975 kernel (version 4.99.10), then you also need a new pthread 976 library (/usr/lib/libpthread.so.0.7). If you boot with 977 an old kernel, then you need the old pthread library 978 (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and 979 the pthread library in sync, old threaded applications should 980 continue to work with an old or new kernel. Note that named(8) 981 is the only threaded application in the base system. 982 98320061214: 984 Following the move of string_to_flags() and flags_to_string() 985 from the bin/ls/ sources to libutil, users doing UPDATE builds 986 will need to do a "make cleandir" in 987 tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/, 988 bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/, 989 usr.bin/xinstall/, libexec/ftpd/, rescue/, as well 990 as the installation images in distrib/ 991 in order to excise stale references to the old stat_flags.h header 992 file in the ls sources -- stat_flags.h has been removed. 993 99420061108: 995 The configure script used in the src/tools/gcc compiler has been 996 changed to indicate that our libc has ssp support built-in and 997 does not depend on -lssp and -lssp-nonshared. You'll need to 998 make clean in src/tools/gcc first to rebuild the compiler. 999 100020061009: 1001 The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer 1002 available. Use net.inet{,6}.tcp{,6}.congctl.selected instead. 1003 100420060814: 1005 The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been 1006 withdrawn. Use vidcvideo and pckbd instead. See the GENERIC 1007 kernel configuration for an example. X servers from the last 1008 few years should cope. 1009 101020060703: 1011 MPACPI is no more. We always configure PCI interrupts using ACPI 1012 if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed 1013 to ACPI_SCANPCI. Thanks to work from fvdl. 1014 101520060627: 1016 socket(2) has changed, and its system call has been versioned. 1017 For userlands with the old version of socket(2), make sure that 1018 your kernel has 'options COMPAT_30' set, or else 'bad system call' 1019 errors will result. 1020 1021Hints for a more successful build: 1022^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 1023 Use build.sh, but do not use its "expert mode": 1024 This will automatically build the tools in the 1025 correct order, and it will keep the tools and the 1026 new build products from interfering with the running 1027 system. This will allow you to ignore most of the 1028 other advice in this file. 1029 Build a new kernel first: 1030 This makes sure that any new system calls or features 1031 expected by the new userland will be present. This 1032 helps to avoid critical errors when upgrading. 1033 Use object directories: 1034 This helps to keep stale object 1035 files from polluting the build if a Makefile "forgets" 1036 about one. It also makes it easier to clean up after 1037 a build. It's also necessary if you want to use the 1038 same source tree for multiple machines. 1039 To use object directories with build.sh: 1040 a) invoke build.sh with the "-M" or "-O" options. 1041 To use object directories without using build.sh: 1042 a) cd /usr/src ; make cleandir 1043 b) Add "OBJMACHINE=yes" to /etc/mk.conf 1044 c) Add "MKOBJDIRS=yes" to /etc/mk.conf 1045 d) cd /usr/src ; make build 1046 Note that running "make obj" in a directory will create 1047 in obj.$MACHINE directory. 1048 Build to a DESTDIR: 1049 This helps to keep old installed files (especially libraries) 1050 from interfering with the new build. 1051 To build to a DESTDIR with build.sh, use the "-D" option. 1052 To build to a DESTDIR without using build.sh, set the DESTDIR 1053 environment variable before running make build. It should be 1054 set to the pathname of an initially empty directory. 1055 Problems: if you do not use build.sh, you might need to 1056 update critical utilities without using DESTDIR since 1057 nothing is executed from what is installed in DESTDIR. 1058 (See critical utils, below.) 1059 Build often: 1060 This keeps critical utilities current enough to not choke 1061 on any other part of the source tree that depends on up to 1062 date functionality. If you use build.sh, you should not have 1063 this problem. 1064 1065What to do if things don't work: 1066^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 1067When things don't work there are usually a few things that commonly 1068should be done. 1069 1) make includes 1070 This should be done automatically by make build. 1071 2) cd share/mk && make install 1072 Again, automatically done by make build. 1073 1074Failsafe rebuild of a small part of the tree: 1075^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 1076To make sure you rebuild something correctly you want to do 1077something like the following: 1078 1) Make sure the includes and .mk files are up to date. 1079 2) Make sure any program used to build the particular 1080 utility is up to date. (yacc, lex, etc...) 1081 3) cd ...path/to/util... 1082 make cleandir 1083 rm ...all obj directories... 1084 make cleandir # yes, again 1085 make obj 1086 make depend && make 1087 1088Failsafe rebuild of the entire tree: 1089^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 1090If you really want to make sure the source tree is clean and 1091ready for a build try the following. Note that sourcing /etc/mk.conf 1092(a make(1) Makefile) in this manner is not right, and will not work 1093for anyone who uses any make(1) features in /etc/mk.conf. 1094 1095---cut here--- 1096#!/bin/sh 1097. /etc/mk.conf 1098 1099if [ -z $NETBSDSRCDIR ] ; then 1100 NETBSDSRCDIR=/usr/src 1101fi 1102if [ \! -d $NETBSDSRCDIR ] ; then 1103 echo Unable to find sources 1104 exit 1 1105fi 1106find $NETBSDSRCDIR -name \*.o -o -name obj.\* -o -name obj -exec rm \{\} \; 1107 1108if [ -z $BSDOBJDIR ] ; then 1109 BSDOBJDIR=/usr/obj 1110fi 1111if [ -d $BSDOBJDIR ] ; then 1112 rm -rf $BSDOBJDIR 1113fi 1114 1115cd $NETBSDSRCDIR && make cleandir 1116 1117---cut here--- 1118 1119Critical utilities: 1120^^^^^^^^^^^^^^^^^^^ 1121 usr.bin/compile_et 1122 usr.bin/make 1123 usr.bin/yacc 1124 usr.bin/lex 1125 usr.bin/xlint 1126 usr.bin/config 1127 1128Other problems and possible solutions: 1129^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 1130Symptom:Complaints involving a Makefile. 1131Fix: Rebuild usr.bin/make: 1132 cd usr.bin/make && make && make install 1133 Or, a failsafe method if that doesn't work: 1134 cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin 1135 1136Fix: Make sure .mk files are up to date. 1137 cd share/mk && make install 1138 1139Symptom:Kernel `config' fails to configure any kernel, including GENERIC. 1140Fix: Rebuild usr.bin/config 1141 1142Symptom: 1143Fix: Rebuild usr.bin/yacc 1144 1145Symptom: 1146Fix: Rebuild usr.bin/lex 1147 1148Symptom: 1149Fix: rm /usr/lib/libbfd.a 1150 1151Symptom:Obsolete intermediate files are used during compilation 1152Fix: Try the following sequence of commands in the directory in question. 1153 make cleandir; rm `make print-objdir`; make cleandir; make obj 1154 (If you built the tree without "make obj" in the past, obsolete files 1155 may remain.

If your cvs working tree 1185 contains references to a directory that has been deleted on the 1186 server in this way, then "cvs update" reports this error. 1187Fix: Recursively delete the affected directory from your working tree 1188 and try the update again. 1189
