UPDATING revision 1.337
1$NetBSD: UPDATING,v 1.337 2023/03/23 07:15:08 mrg 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 2220230322: 23 Fixes for moved /lib/libisns* mean that builds will complain about 24 ./usr/lib/libisns* being missing until src/lib/libisns is forced 25 to (re)install the files, including the symlinks. The simplest 26 way is to clean this subdir before building. 27 2820230112: 29 New binutils require an updated ld.elf_so. If you are doing 30 (unsupported) in-place self builds (with the -E flag to build.sh), 31 make sure to have installed latest ld.elf_so before you rebuild 32 userland. 33 3420221116: 35 36 The addition to NetBSD's version of UFS2 of support for extended 37 attributes broke backward compatibility with previous releases 38 of NetBSD, so UFS2 has been restored to being compatible with 39 previous NetBSD releases by disabling extended attributes. 40 (Note that ACLs are implemented as extended attributes, so 41 this changes disables ACLs as well.) 42 43 Support for UFS2 with extended attributes is now available in a new 44 UFS variant called UFS2ea. If you have created extended attributes 45 in an original UFS2 file system then "fsck -p" will now fail due to 46 the unexpected presence of extended attributes and "fsck -y" will 47 remove all extended attributes. If you wish to preserve extended 48 attributes rather than delete them, there is a utility to convert 49 a UFS2 file system to UFS2ea and leave extended attributes in place, 50 but this should be used with caution since it will preserve any 51 extended attributes that have been corrupted by the backward 52 incompatibility too. 53 54 If you wish to use a UFS2ea file system as your root file system, 55 then you will need to update your boot loader to a version that 56 supports UFS2ea. 57 58 For more information, see: 59 https://wiki.netbsd.org/features/UFS2ea 60 6120221111: 62 The new libdrm import worsened the conflict issues for the 63 kdump/ktruss ioctl, and i915 now conflicts with base, and has 64 been turned off. This will cause update build issues like: 65 66 kdump-ioctl.c:12175:143: error: 'DRM_IOCTL_I915_DESTROY_HEAP' 67 undeclared here (not in a function); 68 did you mean 'DRM_IOCTL_MODE_DESTROY_DUMB'? 69 70 You'll need to clean usr.bin/ktruss, usr.bin/kdump, and rescue. 71 7220220921: 73 Since the kernel version was bumped to 9.99.100, the bootloader 74 must be updated on x86 or EFI boot platforms in order to load 75 modules from boot.cfg(5) or interactively at the bootloader 76 prompt. 77 78 The kernel can still load modules at runtime, with modload(8) 79 or modules.conf(5), with no bootloader update. This will not 80 affect release branches because it only applies to patch 81 numbers >=100. 82 83 On x86 (i386 or amd64) with BIOS boot, this requires copying a 84 new /usr/mdec/boot to /boot. You can build this in the destdir 85 by running `$TOOLDIR/bin/nbmake-$ARCH dependall install' in 86 sys/arch/i386/stand. 87 88 On platforms with EFI boot (including x86 with EFI boot), this 89 requires copying a new /usr/mdec/boot*.efi to the EFI/BOOT/ 90 directory on the EFI system partition. The boot*.efi file is: 91 92 aarch64 bootaa64.efi 93 amd64 bootx64.efi 94 arm bootarm.efi (32-bit arm) 95 i386 bootx32.efi 96 97 You can build this in the destdir by running 98 `$TOOLDIR/bin/nbmake-$ARCH dependall install' in 99 sys/stand/efiboot/boot*. 100 10120220821: 102 Support for building extsrc/ has been deprecated. 103 EXTSRCSRCDIR and MKEXTSRC have been deprecated. 104 10520220714: 106 Updates to xorg-server and associated drivers may cause builds to 107 fail. Cleaning both DESTDIR and the xorg build tree may be needed. 108 10920220628: 110 Changes in the build of src/games/robots require a clean build 111 of that program. 112 11320211116: 114 Changes in the xorg build require clean obj dirs for external/mit/xorg 115 (or a full clean/non-update build). 116 11720211112: 118 Device tree sources were updated for evbarm. Some device nodes 119 (in particular, ld(4) devices on the ROCKPro64) will be renumbered. 120 12120211014: 122 MKPIE default for aarch64 has changed, a clean build is required. 123 12420210917: 125 Changed MNT_ACLS to default to POSIX1e ACLs instead of NFSv4 126 ACLs, to be compatible with FreeBSD. If you are using NFSv4 ACLs 127 and have "acls" in /etc/fstab you'll need to change it to "nfs4acls". 128 12920210711: 130 Updated GMP sources may require cleaning in tools/gmp and/or in 131 external/lgpl3/gmp/lib, particularly if GCC itself does not build. 132 13320210417: 134 GCC 10 was enabled for several platforms. If builds fail in either 135 tools/gcc or external/gpl/gcc, first try cleaning those objects and 136 removing the $DESTDIR/usr/include/g++ subdirectory. 137 13820201230: 139 lint1/ops.c is no longer autogenerated. If this makes the build 140 fail, clean $OBJDIR/tools/*lint* and $OBJDIR/usr.bin/*xlint*. 141 14220201016: 143 MIPS kernel modules have been disabled until they work. This will 144 turn up in extra files in the DESTDIR, which should be cleaned. 145 14620200925: 147 GNU MPC and MPFR have been updated. At least MPFR needs cleaning 148 in both the tools and external dirs. 149 15020200912: 151 GCC 9 has arrived for Arm and x86 platforms, and will be coming 152 for several more, as will binutils 2.34. Clean as required. 153 15420200907: 155 GCC 9 is coming, and binutils has been updated for MIPS. This 156 probably requires cleaning the tools/binutils. 157 15820200811: 159 GCC updates may require cleaning the objdir. This may occur 160 due to GCC 7.5 update, GCC 8.4 move to gcc.old, or the upcoming 161 GCC 9 upgrade. 162 16320200614: 164 blacklist* has been renamed to blocklist*. postinstall(8) 165 should handle the migration. 166 16720200601: 168 Due to a mistake in LIBISPRIVATE handling, .so libraries were 169 created in the build directories and need cleaning. 170 17120200311: 172 GCC 8 ports will need cleaning in src/tools/gcc and 173 src/external/gpl3/gcc due to GCC 8.4 update. 174 17520191118: 176 More architectures were switched to gcc8: 177 i386, ia64 powerpc64, sparc, sparc64, arm 178 The same comments as in 20191022 apply. 179 18020191112: 181 The LLVM update requires a clean rebuild for all architectures using 182 LLVM during the tools build phase (i386, amd64, aarch64). 183 18420191022: 185 Ports amd64 and aarch64 switched to GCC 8.3 by default. 186 In-place ("expert mode", build.sh -E) builds are not supported 187 when going from a GCC 7 userland to GCC 8. Do a regular 188 build to a different DESTDIR (or preferably: build.sh -U) at least 189 once and install sets, or download comp.{tar.xz,tgz} from the 190 daily builds and install that before doing the next in-place build. 191 19220191001: 193 GCC 8.3 was imported. Builds of src/tools/gcc may fail if 194 old builds with GCC 7 output now uses GCC 8. Clean this 195 directory, and also clean src/external/gpl3/gcc. 196 19720190903: 198 Files with names that coincide with existing files' names on 199 case-insensitive file systems were inadvertently committed, for 200 radeon GPU firmware. We cannot mark these as obsolete for 201 postinstall to fix, so if you updated src since 2019-08-26, and 202 ran build.sh distribution or ran build.sh release, you must 203 manually delete the following files in your DESTDIR (which is 204 usually $OBJDIR/destir.$ARCH), or from / if you have installed 205 them: 206 207 /libdata/firmware/radeon/bonaire_ce.bin 208 /libdata/firmware/radeon/bonaire_mc.bin 209 /libdata/firmware/radeon/bonaire_me.bin 210 /libdata/firmware/radeon/bonaire_mec.bin 211 /libdata/firmware/radeon/bonaire_pfp.bin 212 /libdata/firmware/radeon/bonaire_rlc.bin 213 /libdata/firmware/radeon/bonaire_sdma.bin 214 /libdata/firmware/radeon/bonaire_smc.bin 215 /libdata/firmware/radeon/bonaire_uvd.bin 216 /libdata/firmware/radeon/hainan_ce.bin 217 /libdata/firmware/radeon/hainan_mc.bin 218 /libdata/firmware/radeon/hainan_me.bin 219 /libdata/firmware/radeon/hainan_pfp.bin 220 /libdata/firmware/radeon/hainan_rlc.bin 221 /libdata/firmware/radeon/hainan_smc.bin 222 /libdata/firmware/radeon/hawaii_ce.bin 223 /libdata/firmware/radeon/hawaii_mc.bin 224 /libdata/firmware/radeon/hawaii_me.bin 225 /libdata/firmware/radeon/hawaii_mec.bin 226 /libdata/firmware/radeon/hawaii_pfp.bin 227 /libdata/firmware/radeon/hawaii_rlc.bin 228 /libdata/firmware/radeon/hawaii_sdma.bin 229 /libdata/firmware/radeon/hawaii_smc.bin 230 /libdata/firmware/radeon/kabini_ce.bin 231 /libdata/firmware/radeon/kabini_me.bin 232 /libdata/firmware/radeon/kabini_mec.bin 233 /libdata/firmware/radeon/kabini_pfp.bin 234 /libdata/firmware/radeon/kabini_rlc.bin 235 /libdata/firmware/radeon/kabini_sdma.bin 236 /libdata/firmware/radeon/kaveri_ce.bin 237 /libdata/firmware/radeon/kaveri_me.bin 238 /libdata/firmware/radeon/kaveri_mec.bin 239 /libdata/firmware/radeon/kaveri_mec2.bin 240 /libdata/firmware/radeon/kaveri_pfp.bin 241 /libdata/firmware/radeon/kaveri_rlc.bin 242 /libdata/firmware/radeon/kaveri_sdma.bin 243 /libdata/firmware/radeon/mullins_ce.bin 244 /libdata/firmware/radeon/mullins_me.bin 245 /libdata/firmware/radeon/mullins_mec.bin 246 /libdata/firmware/radeon/mullins_pfp.bin 247 /libdata/firmware/radeon/mullins_rlc.bin 248 /libdata/firmware/radeon/mullins_sdma.bin 249 /libdata/firmware/radeon/oland_ce.bin 250 /libdata/firmware/radeon/oland_mc.bin 251 /libdata/firmware/radeon/oland_me.bin 252 /libdata/firmware/radeon/oland_pfp.bin 253 /libdata/firmware/radeon/oland_rlc.bin 254 /libdata/firmware/radeon/oland_smc.bin 255 /libdata/firmware/radeon/pitcairn_ce.bin 256 /libdata/firmware/radeon/pitcairn_mc.bin 257 /libdata/firmware/radeon/pitcairn_me.bin 258 /libdata/firmware/radeon/pitcairn_pfp.bin 259 /libdata/firmware/radeon/pitcairn_rlc.bin 260 /libdata/firmware/radeon/pitcairn_smc.bin 261 /libdata/firmware/radeon/tahiti_ce.bin 262 /libdata/firmware/radeon/tahiti_mc.bin 263 /libdata/firmware/radeon/tahiti_me.bin 264 /libdata/firmware/radeon/tahiti_pfp.bin 265 /libdata/firmware/radeon/tahiti_rlc.bin 266 /libdata/firmware/radeon/tahiti_smc.bin 267 /libdata/firmware/radeon/verde_ce.bin 268 /libdata/firmware/radeon/verde_mc.bin 269 /libdata/firmware/radeon/verde_me.bin 270 /libdata/firmware/radeon/verde_pfp.bin 271 /libdata/firmware/radeon/verde_rlc.bin 272 /libdata/firmware/radeon/verde_smc.bin 273 274 We will re-import these radeon firmware images another way 275 later. 276 27720190727: 278 The uefi bootloader has gained tftp support and needs a clean 279 build. If you do update builds, manually clean its object 280 directory by something like: 281 cd sys/arch/i386/stand/efiboot && make clean 282 28320190723: 284 The jemalloc allocator in libc is now build without extended 285 debugging (for performance reasons). In update builds make sure 286 to rebuild it completely, by removing all affected object files, 287 including compat builds, something like: 288 cd /usr/obj && find . -type d -name jemalloc|xargs rm -rf 289 29020190207: 291 GCC 7 switched for many ports. Update builds are likely to fail. 292 29320180924: 294 A newer OpenSSL version has been imported. If you are doing 295 update builds, make sure to remove all old obj dirs, like: 296 cd /usr/obj && find . -type d -name openssl | xargs rm -rf 297 29820180717: 299 On aarch64 int64_t and related types have changed from long long 300 to long. This requires recompiling all C++ binaries. 301 30220180713: 303 On amd64 and i386 static binaries are now build position 304 independend. This requires recompilation of all object 305 files used to create the crunched /rescue binary. 306 Clean the rescue directory in your obj directory before 307 doing an update build, otherwise linking will fail. 308 30920180414: 310 Existing binutils was migrated to binutils.old. Manual 311 removal of tools/binutils objects directory may be required 312 to fix tools build failure. 313 31420180311: 315 bdftopcf was updated and may need cleaning in the 316 src/external/mit/xorg/tools/bdftopcf subdirectory if there are 317 link errors. 318 31920180212: 320 between OpenSSL and GCC updates, many things may fail to build. 321 any failure that looks like GCC or openssl is best handled by 322 a clean destdir and objdir. Full cleandir and destdir deletion 323 is recommended if build failures occur. 324 32520171225: 326 removal of the vadvise syscall requires manual removal of all 327 associated files from the libc build object directory (including 328 the .depend files) - a command like: 329 cd $OBJ && find . -type d -name libc | xargs rm -rf 330 For architectures that support multiple "compat" binary targets, 331 you'll need to cleanup both the regular libc directory and the 332 compat ones (the above command will do that). 333 33420171010: 335 a change to the build structure of external/bsd/acpica/bin/iasl 336 means that its objdir (or *.d and .depend at least) might need 337 to be manually removed - or a build done once without -u. 338 33920170822: 340 a new version of GMP has been imported and probably 341 will break parts of builds related to themselves or GCC, both 342 in the tools and the native section. Remove all GCC, GMP, MPFR 343 and MPC objdirs or build once without -u. 344 34520170816: 346 a new version of MPFR and MPC have been imported and probably 347 will break parts of builds related to themselves or GCC, both 348 in the tools and the native section. Remove all GCC, GMP, MPFR 349 and MPC objdirs or build once without -u. 350 35120170402: 352 a new version of dhcpcd has been imported, which does not support 353 update builds from the previous version. Remove your 354 external/bsd/dhcpcd object dir or build once without -u. 355 35620170211: 357 a new terminfo database has been imported. 358 The structure of it has changed slightly from prior versions and 359 an updated tic tool is required. 360 If you build.sh, don't use -u 361 36220170207: 363 various arch dependent libc/exect.S files were removed 364 Either remove the obj directories (lib/libc and compat/amd64/i386/lib 365 if it exists) or do a clean build. 366 (This is a bug in the make system, it should be corrected without 367 human intervention, but isn't.) 368 36920170104: 370 xinput build options have changed. 371 Remove the obj directory (external/mit/xorg/bin/xinput) 372 if you build.sh -u 373 37420170103: 375 a new version of flex has been imported. 376 Remove the file from obj (external/bsd/flex) 377 if you build.sh -u 378 37920161014: 380 a new version of OpenSSL has been imported. 381 Remove the files from obj (crypto/external/bsd/openssl) 382 if you build.sh -u 383 38420161009: 385 a new version of dhcpcd has been imported with slightly changed 386 build infrastructure. When doing a build.sh -u this requires 387 pruning the external/bsd/dhcpcd objdir. 388 38920160914: 390 i386, amd64, shark, ofppc and macppc have joined shark and x68k 391 ports in using xorg-server 1.18. This requires a clean destdir 392 and a clean objdir. 393 39420160527: 395 i386 needs a full cleandir or objdir deletion because PIE has 396 been enabled. (see the amd64 entry two down for further info) 397 39820160418: 399 libedit needs manual removal of all autogenerated files since 400 some of them are not autogenerated anymore. Remember that there 401 might be two copies of libedit if your platform builds "compat". 402 40320160410: 404 amd64 needs full "make cleandir" or deletion of objdir now that 405 PIE has been enabled for amd64. PIE, or position-independent 406 executables, means all code, including executables and not just 407 shared libraries, is position-independent and hence able to be 408 relocated by ASLR, address space layout randomization. 409 410 The change was made in Makefile variables for compiler and 411 linker flags, for which make(1) does not record dependencies, 412 hence it is unable to detect that all .o files need rebuilding. 413 414 Partial rebuilds with some modified source files will likely 415 fail when linking executables, since the linker refuses to mix 416 position-independent code with position-dependent code in 417 position-independent executables: 418 419 .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC 420 42120160401: 422 Ports switching to GCC 5.3 will need a full "make cleandir". 423 Some people have found that cleandir is not sufficient, so if 424 in doubt delete the entire object directory tree for gcc. 425 42620160306: 427 NetBSD's regexp implementation is now part of libnbcompat. 428 Nblex, nbm4, nbpax, nbsed use it and they may crash on 429 non-NetBSD hosts if linked with stale object files produced 430 while they included a non-NetBSD regex.h. 431 In any case, you should "make cleandir" at least these tools 432 before updating your toolchain. 433 43420160125: 435 Dtrace has been enabled by default on some architectures. 436 When doing an update build, make sure to clean the etc/mtree 437 object directory before starting the build - otherwise the 438 needed directories in destdir will not be created. 439 An easy way to do this is: 440 cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir 441 44220150818: 443 New acpica requires "make cleandir" in src/external/bsd/acpica 444 again. 445 44620150413: 447 New acpica requires "make cleandir" and reinstalling yacc 448 in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and 449 also "make cleandir" in /usr/src/external/bsd/acpica. 450 45120150404: 452 Lint changes require a full rebuild of the tool, so make 453 sure to build without -u option to build.sh, or manually 454 do a make cleandir in src/tools/lint1 and 455 src/usr.bin/xlint. 456 45720150310: 458 Improvements to openssl for arm mean that update builds of 459 the openssl libraries will fail. A make cleandir in 460 external/bsd/openssl/lib is needed 461 46220141026: 463 A mishap during the import of pppd may cause your corruption 464 in your cvs directory if you happened to do a cvs update 465 during a short period of time. To fix, just remove the 466 directory src/external/bsd/ppp/dist/pppd completely 467 and let cvs restore it on next update. 468 46920140721: 470 The src/external/mit/lua/src directory was accidentally created 471 and then deleted in the CVS repository. If you get errors like 472 473 cvs [update aborted]: cannot open directory 474 /cvsroot/src/external/mit/lua/src: No such file or directory 475 476 then delete your local copy of that directory tree and try again. 477 47820140530: 479 ARM eABI switched to DWARF based exception handling. This requires 480 rebuilding all C++ code. It is strongly advised to do a clean build. 481 48220140131: 483 The new compiler_rt/libc integration moved a few things. It is strongly 484 advised to do a clean build. At least lib/libc, the compat version(s) 485 of libc, libkern, rump and the kernels need to be cleaned. 486 48720131227: 488 1. The new ntpd runs in a restricted mode to prevent amplification 489 attacks. If you need ntpdc to work you need to explicitly enable 490 mode7 in your config file. Make sure you put the necessary restrict 491 statements to avoid being exposed. 492 2. strncat has moved from lib/libc to common/lib/libc; you might need 493 to make clean in libc 494 49520131129: 496 The GMP sources were updated, and builds will likely fail without 497 cleaning their build trees for both tools and in-tree, like below. 498 49920131128: 500 The MPC and MPFR sources were updated, and builds may require their 501 tools and in-tree directories cleaned for successful updates. 502 50320130605: 504 The kernel option FAST_IPSEC no longer exists, it's been renamed 505 to IPSEC (and the older IPSEC version removed). 506 50720130605: 508 Previous freetype installations erroneously installed private 509 header files. If you are building against a non-empty $DESTDIR, 510 please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/. 511 51220130531: 513 The xdm update may cause build failure due to xdm.man being 514 in the obj tree. Make sure to ensure any like this: 515 nbmake: nbmake: don't know how to make xdm.man. Stop 516 is fixed by deleting the xdm.man in the obj tree. 517 51820130530: 519 Updates of many xsrc packages will leave old .pc files around. 520 Best to clean out the xsrc objdir entirely before rebuilds. 521 52220130301: 523 The removal of netiso requires manual removal of /usr/include/netiso 524 prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump} 525 52620120726: 527 The update of OpenSSL requires cleaning both the OpenSSL build 528 directory and DESTDIR. *Even non-update builds require cleaning 529 DESTDIR.* Builds done without taking these steps may fail, or in 530 some cases may succeed and install broken OpenSSL libraries that 531 cause third-party software to link incorrectly and/or crash. 532 53320120507: 534 The database schema for makemandb was changed. You will 535 need to update the database using 'makemandb -f' or wait 536 for the next weekly run to fix it. 537 53820120319: 539 sys/conf/Makefile.kern.inc has been modified to adjust the 540 size of db_symtab automatically. You need to update dbsym in 541 your $TOOLDIR to build kernels with options SYMTAB_SPACE. If 542 you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your 543 mk.conf. 544 54520120216: 546 Default for MKCATPAGES changed to NO. Update builds will fail 547 unless DESTDIR is cleaned manually. If you built between 20120207 548 and 20120216, daily and weekly could have created an unreadable 549 /var/db/man.db index for apropos. Running makemandb -f or 550 the next run of weekly will fix it. 551 55220111227: 553 If you built between 20111225 and 20111227 you need to remove 554 /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the 555 bump has been reverted. 556 55720111125: 558 The "rnd" pseudodevice has been added to sys/conf/std, which 559 means it should no longer be explicitly listed in kernel 560 configuration files. The line "pseudo-device rnd" should be 561 removed from any custom kernel config files users may have. 562 56320111119: 564 A problem with the datastructures used by the rndctl(8) 565 utility (pointers in datastructures in an array, making 32->64 566 bit compatibility very painful) has been fixed in a 567 non-backwards-compatible way. If you replace your kernel, 568 replace your rndctl executable too. 569 57020111001: 571 the prop_*_send_syscall() functions from proplib(3) have been 572 changed and their new version is not backward compatible with the old 573 one. So ensure that all consumers of these functions (currently: 574 quota2 code and its tests) are updated together with the new lib. 575 57620110817: 577 sparc has been changed to use GCC 4.5.3, so any objdir or 578 DESTDIR for them should be deleted before updating. 579 58020110806: 581 i386 and amd64 have been changed to use GCC 4.5.3, so any 582 objdir or DESTDIR for them should be deleted before updating. 583 58420110805: 585 The update to GCC 4.5.3 requires a non-trivial portion of 586 the tree to be cleaned. Best to delete both objdir and 587 DESTDIR before running this update. So far, only the 588 sparc64, mips and powerpc platforms have changed. 589 59020110803: 591 The layout of external/public-domain/xz has changed. To do an 592 update build you will have to remove the contents of the OBJDIR 593 for external/public-domain/xz/bin by hand as the xz entry there 594 is now a directory. 595 59620110410: 597 The configuration of src/tools/gcc has changed. To do an 598 update build you have to clean both tools/binutils and 599 tools/gcc by hand. 600 60120110328: 602 Building the Xorg binary was moved into a subdirectory to fix 603 ordering issues with "make all". It may be necessary to remove 604 the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86 605 if your update build fails, as the "Xorg" entry there is now a 606 directory. 607 60820110121: 609 Assembler files no longer use -traditional-cpp. This can break 610 the build of individual parts of the tree. This is handled 611 correctly by build.sh. Manual builds have to update /usr/share/mk 612 and re-run config(1) for any kernel configurations as needed. 613 61420101217: 615 The tcpdump(8) program was changed to drop privileges and chroot(2) 616 by default. It may be necessary to manually update passwd(5) and 617 group(5) in order to make the program work with existing setups. 618 61920101125: 620 The latest changes to setenv(3) disallow setting environment 621 variables with names that contain '='. Revision 1.18 of env.c 622 assumed that this was allowed. Installing a new libc with an 623 old copy of /usr/bin/env causes env x=1 printenv | grep x= to 624 break which affects the autoconf tests for dependency finding, 625 so building gcc will end up printing: 626 checking dependency style of gcc... none 627 configure: error: no usable dependency style found 628 Fix it by rebuilding and re-installing env. 629 63020101119: 631 Recent Xorg updates in xsrc/external/mit/ may cause various build 632 or run-time problems. Delete your entire DESTDIR and OBJDIR if you 633 have any build problems with xsrc, or problems with mismatched 634 versions between xorg-server and drivers. 635 63620100604: 637 The update of ATF to 0.9 causes old tests written in shell to fail 638 unless they are rebuilt. If you are building with MKUPDATE=yes, 639 you need to clean the src/external/bsd/atf/tests/ and the src/tests/ 640 trees by hand. 641 64220100522: 643 Recent Xorg updates in xsrc/external/mit/ will cause various build 644 problems. Delete your entire DESTDIR and OBJDIR if you have any 645 build problems with xsrc. 646 64720100522: 648 private section of <ctype.h> was split, and now mklocale(1) 649 include ctype_local.h, so you have to make cleandir in tools/mklocale. 650 65120100520: 652 The location of the xkb compiled descriptions has changed. Please 653 remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR. 654 65520100222: 656 The shared objects file extension has been changed from .so to 657 .pico, in order to avoid conflicts with shared libraries names 658 libXX.so. All now stale regular .so files can be removed from 659 your object directories. 660 66120100204: 662 The termcap database has been removed from the sources, 663 but has not been marked obsolete so it is not removed 664 from the system when upgrading. 665 As such, you will need to remove them from your object 666 and destination directories. 667 66820091101: 669 After updating, it may be necessary to make the 'cleandir' 670 target in src/tools/yacc/ and in src/usr.bin/yacc/ before a 671 'build.sh -u tools' or 'build.sh -u distribution'. Ditto 672 src/tools/lex/ and src/usr.bin/lex/. 673 67420091001: 675 On amd64 you must rebuild tools (to get the new binutils) 676 before building a kernel, or the build fails on cpufunc.S. 677 67820091001: 679 An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb 680 symlink, failing the build. Delete the link, and the subdir 681 it is in, and retry your build. 682 68320090718: 684 libc build changed so that strchr() provides the extra entry 685 point for index(). Update build of libc.a (and libc_pic.a) 686 may fail because the archive contains the unwanted index.o. 687 (Similarly for strrchr() and rindex().) 688 68920090709: 690 Native Xorg was upgraded again. Builds will probably fail again 691 without a clean objdir, at least for src/external/mit/xorg. 692 69320090616: 694 Native Xorg was upgraded. Builds will need a clean objdir for 695 src/external/mit/xorg. Upgrading a system from sets will not 696 work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc 697 subdirectory has been changed into a file, and this needs to 698 be manually "rm -r"'ed before installing xbase.tgz. 699 70020090501: 701 Several new functions were added to string.h/libc, and this 702 can cause autoconf problems during the tool build for people 703 who fail to clean out their tools objects properly. If you 704 note messages about stpcpy, stpncpy or strnlen accompanying a 705 failure during the tool build, clean out all your tools 706 objects and start again. 707 70820090325: 709 The i386 port was switched to i486 default toolchain. This requires 710 cleaning your src/tools directory and $TOOLDIR and rebuilding them. 711 71220090126: 713 The __posix_fadvise50 system call changed assembly stub type. You 714 need to 'rm -f __posix_fadvise50.*' in the libc build directory 715 to avoid using the old assembly stub. 716 71720090202: 718 pkg_install now depends on the pkgdb cache for automatic conflict 719 detection. It is recommended to rebuild the cache with 720 ``pkg_admin rebuild''. 721 72220090110: 723 time_t and dev_t have been bumped to 64 bit quantities. To upgrade: 724 1. Make sure your kernel has COMPAT_50 in it. Build and install. 725 This is needed even in the MODULAR kernel because there is 726 conditionally compiled code in rtsock.c. 727 2. make sure build.sh completes and the binaries in a chroot work 728 before installing. 729 3. If you don't use build.sh and you build directly to root, and 730 your build breaks in the middle, don't despair. Make sure headers 731 are installed properly, and start building libraries first libc 732 and libutil, install them and then continue building all the 733 libraries in src/lib and src/gnu/lib and install them. Once 734 the new libraries are installed, you can restart the build. 735 4. If you compile packages and you notice link time warnings, 736 rebuild the required packages to update their shared libraries. 737 Any package you rebuild will require rebuilding all the packages 738 that depend on it. 739 5. Next time you run pwd_mkdb with the new binary, the file 740 will be upgraded and it will not be backwards compatible. 741 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see 742 lastlogx(5)) have been versioned, and there is a heuristic 743 for utmp. You are better off removing the old files after 744 upgrading. The automated clearing of /var/run during 745 boot, and the automated rotating of files in /var/log by 746 newsyslog(8), may mean that you do not have to remove the 747 files manually. 748 7. The optional accounting file (/var/account/acct, see 749 accton(8)) has not been versioned, and will need to be 750 removed. The automatic rotation of the accounting file by 751 /etc/daily limits the bad consequences of failure to remove 752 the file. 753 8. Application software that writes time_t to binary files on 754 disk will break or need attention. Most notably: if you are 755 using PostgreSQL < 8.4, you need to dump your databases, 756 rebuild PostgreSQL with the new time_t, then restore. 757 75820081219: 759 config(1) has been updated, and one of the files it creates - 760 swapnetbsd.o - has changed format. You need to rebuild config 761 (done automatically by build.sh) and then you need to rerun 762 config on all kernel configuration files before rebuilding those 763 kernels. 764 76520081205: 766 If you build with MKX11=no, you should remove /etc/rc.d/xdm and 767 /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc 768 set and will appear as extra files for MKX11=no update builds. 769 77020081122: 771 On i386, various kernel options(4) in GENERIC including 772 file systems have been disabled and moved into kernel modules. 773 Before trying a new GENERIC kernel, you have to prepare the 774 following files as well as a new GENERIC kernel: 775 776 - build and install kernel modules from src/sys/modules 777 778 - install the latest bootloader, which will load a module 779 for the file system from which the kernel is loaded automatically 780 781 If you have to load your kernel from a file system which is not of 782 the same type as the root file system, you have to load the necessary 783 file system module manually on the boot prompt or in the boot.cfg file. 784 78520080827: 786 If you built and installed a libc from sources between 787 2008/08/20 and 2008/08/26 you got a broken strtouq(3) 788 which results in false errors reported by lint(1). 789 Since this breaks the libc build itself, manual help is 790 needed -- lint must be disabled temporarily, e.g.: 791 $ (cd lib/libc && make MKLINT=no dependall install) 792 79320080813: 794 MKDEBUG build was broken because the .depend files did not know 795 about .go files. You need to remove all .depend files and rebuild. 796 79720080802: 798 A regression in binary compatibility for pthread_mutex_t has 799 been fixed. Unfortunately, the price is breaking compatibility 800 for -current. 801 802 Threaded programs (using libpthread) and C++ programs (using 803 libstdc++) compiled after 20070907 and before 20080802 need to 804 be recompiled. 805 806 One way to find affected pkgsrc packages: 807 808 $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO 809 $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO 810 81120080731: 812 WAPBL (metadata journaling support) has been added, but at this 813 time isn't backwards compatible with pre-WAPBL aware kernels 814 and userland (fsck_ffs in particular). Please make sure you 815 don't use a journaled filesystem with an older kernel/userland, 816 especially an uncleanly mounted journaled filesystem. WAPBL 817 also requires the super block to be in the UFS2 format. You 818 can use fsck_ffs -c 4 to update the superblock format. 819 82020080721: 821 Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR 822 isn't defined. 823 82420080531: 825 The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed 826 from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8) 827 utility needs to be rebuilt and reinstalled as older binaries 828 won't work correctly. The following sequence of commands: 829 830 $ (cd sys/sys/ && nbmake-$arch includes) 831 $ (cd sbin/drvctl/ && nbmake-$arch clean) 832 $ (cd sbin/drvctl/ && nbmake-$arch all) 833 834 leaves new drvctl utility in sbin/drvctl build directory. 835 83620080503: 837 The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE. 838 83920080521: 840 For a while, unprivileged UPDATE builds would fail to 841 succeed at the checkflist stage, complaining that 842 ${DESTDIR}/stand/<arch>/ did not exist. A fix for this 843 problem was committed to share/mk/bsd.kmodule.mk, revision 1.9. 844 If you already hit this problem, update the .mk file, 845 remove ${DESTDIR}/stand/<arch>, and re-run the build. 846 84720080303: 848 Linker warnings are now fatal if $WARNS>0. 849 85020080126: 851 The posix_fadvise system call has been changed from an assembly 852 stub, to a c file that calls an assembly stub. You need to 853 'rm -f posix_fadvise.* .depend' in the libc build directory to 854 avoid using the old assembly stub. 855 85620071209: 857 The acpiec(4) driver has been split into two attachments. If you 858 get ACPI errors before the attachment, please update your kernel 859 configuration file appropriately or see GENERIC for more details. 860 86120071115: 862 The it(4) driver has been renamed to itesio(4) and the old port 863 argument specified in the kernel configuration file is not valid 864 anymore. The itesio(4) driver now uses the Super I/O address port 865 rather than the EC address port. Please update your kernel 866 configuration file appropriately or see GENERIC for more details. 867 86820071028: 869 The pccons(4) driver has been removed from the NetBSD/shark port. 870 You need to update any custom kernel configuration file you have 871 to remove any references to pccons (which includes removing the 872 now useless XSERVER option) and replace them with the correct 873 entries for the wscons driver. See the GENERIC configuration file 874 for more details. 875 87620070913: 877 A latent bug in dhclient/dhcpd that caused it to be unable to 878 enumerate interfaces was fixed. The bug began to cause 879 problems after 20070911 when the kernel's SIOCGIFCONF 880 implementation was repaired. From 20070529 to 20070911 racoon 881 could not enumerate interfaces. (These are noted because 882 normal kernel/userspace version matching hygiene is not 883 sufficient to avoid this problem.) Ensure that both kernel 884 and userland are from after 20070913. 885 88620070703: 887 nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It 888 calls the target-specific strip program, and the logic to pass 889 down STRIP from make has been removed. This requires a 890 re-installation of tools. 891 89220070422: 893 The way OS emulations lookup filenames inside the emulation root 894 has been changed. Rather than modify the pathname (and copy back 895 to userspace) namei() and lookup() directly check the emulation 896 root. One side effect is that absolute symlinks inside the emulated 897 root file system will be relative to that file system - unless they 898 start /../ this is useful when the emulated root is a real install 899 that has such links. 900 This might affect symlinks that have been added to reference outside 901 the emulated root. 902 90320070412: 904 The pckbc driver on sgimips IP32 has been removed. Use macekbc 905 instead. See the GENERIC32_IP3x kernel configuration for an 906 example. 907 90820070319: 909 src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so 910 on many platforms due to incorrect flags settings. If you 911 updated and built after about 20070315, do "nbmake-$arch 912 cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a 913 rebuild of object files that might have been built 914 incorrectly, and ensure that you have at least 915 src/lib/libc/Makefile 1.130. 916 91720070210: 918 src/sys/sys/{sa.h,savar.h} were removed. 919 find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \ 920 | xargs egrep -l '/sa.h|/savar.h' | xargs rm 921 will allow dependencies on those files to get get rebuilt 922 92320070209: 924 The threading model was changed when the newlock2 branch 925 was merged to NetBSD-current. If you boot with a new 926 kernel (version 4.99.10), then you also need a new pthread 927 library (/usr/lib/libpthread.so.0.7). If you boot with 928 an old kernel, then you need the old pthread library 929 (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and 930 the pthread library in sync, old threaded applications should 931 continue to work with an old or new kernel. Note that named(8) 932 is the only threaded application in the base system. 933 93420061214: 935 Following the move of string_to_flags() and flags_to_string() 936 from the bin/ls/ sources to libutil, users doing UPDATE builds 937 will need to do a "make cleandir" in 938 tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/, 939 bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/, 940 usr.bin/xinstall/, libexec/ftpd/, rescue/, as well 941 as the installation images in distrib/ 942 in order to excise stale references to the old stat_flags.h header 943 file in the ls sources -- stat_flags.h has been removed. 944 94520061108: 946 The configure script used in the src/tools/gcc compiler has been 947 changed to indicate that our libc has ssp support built-in and 948 does not depend on -lssp and -lssp-nonshared. You'll need to 949 make clean in src/tools/gcc first to rebuild the compiler. 950 95120061009: 952 The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer 953 available. Use net.inet{,6}.tcp{,6}.congctl.selected instead. 954 95520060814: 956 The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been 957 withdrawn. Use vidcvideo and pckbd instead. See the GENERIC 958 kernel configuration for an example. X servers from the last 959 few years should cope. 960 96120060703: 962 MPACPI is no more. We always configure PCI interrupts using ACPI 963 if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed 964 to ACPI_SCANPCI. Thanks to work from fvdl. 965 96620060627: 967 socket(2) has changed, and its system call has been versioned. 968 For userlands with the old version of socket(2), make sure that 969 your kernel has 'options COMPAT_30' set, or else 'bad system call' 970 errors will result. 971 972Hints for a more successful build: 973^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 974 Use build.sh, but do not use its "expert mode": 975 This will automatically build the tools in the 976 correct order, and it will keep the tools and the 977 new build products from interfering with the running 978 system. This will allow you to ignore most of the 979 other advice in this file. 980 Build a new kernel first: 981 This makes sure that any new system calls or features 982 expected by the new userland will be present. This 983 helps to avoid critical errors when upgrading. 984 Use object directories: 985 This helps to keep stale object 986 files from polluting the build if a Makefile "forgets" 987 about one. It also makes it easier to clean up after 988 a build. It's also necessary if you want to use the 989 same source tree for multiple machines. 990 To use object directories with build.sh: 991 a) invoke build.sh with the "-M" or "-O" options. 992 To use object directories without using build.sh: 993 a) cd /usr/src ; make cleandir 994 b) Add "OBJMACHINE=yes" to /etc/mk.conf 995 c) Add "MKOBJDIRS=yes" to /etc/mk.conf 996 d) cd /usr/src ; make build 997 Note that running "make obj" in a directory will create 998 in obj.$MACHINE directory. 999 Build to a DESTDIR: 1000 This helps to keep old installed files (especially libraries) 1001 from interfering with the new build. 1002 To build to a DESTDIR with build.sh, use the "-D" option. 1003 To build to a DESTDIR without using build.sh, set the DESTDIR 1004 environment variable before running make build. It should be 1005 set to the pathname of an initially empty directory. 1006 Problems: if you do not use build.sh, you might need to 1007 update critical utilities without using DESTDIR since 1008 nothing is executed from what is installed in DESTDIR. 1009 (See critical utils, below.) 1010 Build often: 1011 This keeps critical utilities current enough to not choke 1012 on any other part of the source tree that depends on up to 1013 date functionality. If you use build.sh, you should not have 1014 this problem. 1015 1016What to do if things don't work: 1017^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 1018When things don't work there are usually a few things that commonly 1019should be done. 1020 1) make includes 1021 This should be done automatically by make build. 1022 2) cd share/mk && make install 1023 Again, automatically done by make build. 1024 1025Failsafe rebuild of a small part of the tree: 1026^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 1027To make sure you rebuild something correctly you want to do 1028something like the following: 1029 1) Make sure the includes and .mk files are up to date. 1030 2) Make sure any program used to build the particular 1031 utility is up to date. (yacc, lex, etc...) 1032 3) cd ...path/to/util... 1033 make cleandir 1034 rm ...all obj directories... 1035 make cleandir # yes, again 1036 make obj 1037 make depend && make 1038 1039Failsafe rebuild of the entire tree: 1040^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 1041If you really want to make sure the source tree is clean and 1042ready for a build try the following. Note that sourcing /etc/mk.conf 1043(a make(1) Makefile) in this manner is not right, and will not work 1044for anyone who uses any make(1) features in /etc/mk.conf. 1045 1046---cut here--- 1047#!/bin/sh 1048. /etc/mk.conf 1049 1050if [ -z $NETBSDSRCDIR ] ; then 1051 NETBSDSRCDIR=/usr/src 1052fi 1053if [ \! -d $NETBSDSRCDIR ] ; then 1054 echo Unable to find sources 1055 exit 1 1056fi 1057find $NETBSDSRCDIR -name \*.o -o -name obj.\* -o -name obj -exec rm \{\} \; 1058 1059if [ -z $BSDOBJDIR ] ; then 1060 BSDOBJDIR=/usr/obj 1061fi 1062if [ -d $BSDOBJDIR ] ; then 1063 rm -rf $BSDOBJDIR 1064fi 1065 1066cd $NETBSDSRCDIR && make cleandir 1067 1068---cut here--- 1069 1070Critical utilities: 1071^^^^^^^^^^^^^^^^^^^ 1072 usr.bin/compile_et 1073 usr.bin/make 1074 usr.bin/yacc 1075 usr.bin/lex 1076 usr.bin/xlint 1077 usr.bin/config 1078 1079Other problems and possible solutions: 1080^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 1081Symptom:Complaints involving a Makefile. 1082Fix: Rebuild usr.bin/make: 1083 cd usr.bin/make && make && make install 1084 Or, a failsafe method if that doesn't work: 1085 cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin 1086 1087Fix: Make sure .mk files are up to date. 1088 cd share/mk && make install 1089 1090Symptom:Kernel `config' fails to configure any kernel, including GENERIC. 1091Fix: Rebuild usr.bin/config 1092 1093Symptom: 1094Fix: Rebuild usr.bin/yacc 1095 1096Symptom: 1097Fix: Rebuild usr.bin/lex 1098 1099Symptom: 1100Fix: rm /usr/lib/libbfd.a 1101 1102Symptom:Obsolete intermediate files are used during compilation 1103Fix: Try the following sequence of commands in the directory in question. 1104 make cleandir; rm `make print-objdir`; make cleandir; make obj 1105 (If you built the tree without "make obj" in the past, obsolete files 1106 may remain.

If your cvs working tree 1136 contains references to a directory that has been deleted on the 1137 server in this way, then "cvs update" reports this error. 1138Fix: Recursively delete the affected directory from your working tree 1139 and try the update again. 1140
