UPDATING revision 1.313
1$NetBSD: UPDATING,v 1.313 2020/09/07 10:19:02 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 2220200907: 23 GCC 9 is coming, and binutils has been updated for MIPS. This 24 probably requires cleaning the tools/binutils. 25 2620200811: 27 GCC updates may require cleaning the objdir. This may occur 28 due to GCC 7.5 update, GCC 8.4 move to gcc.old, or the upcoming 29 GCC 9 upgrade. 30 3120200614: 32 blacklist* has been renamed to blocklist*. postinstall(8) 33 should handle the migration 34 3520200601: 36 Due to a mistake in LIBISPRIVATE handling, .so libraries were 37 created in the build directories and need cleaning. 38 3920200311: 40 GCC 8 ports will need cleaning in src/tools/gcc and 41 src/external/gpl3/gcc due to GCC 8.4 update. 42 4320191118: 44 More architectures were switched to gcc8: 45 i386, ia64 powerpc64, sparc, sparc64, arm 46 The same comments as in 20191022 apply. 47 4820191112: 49 The LLVM update requires a clean rebuild for all architectures using 50 LLVM during the tools build phase (i386, amd64, aarch64). 51 5220191022: 53 Ports amd64 and aarch64 switched to GCC 8.3 by default. 54 In-place ("expert mode", build.sh -E) builds are not supported 55 when going from a GCC 7 userland to GCC 8. Do a regular 56 build to a different DESTDIR (or preferably: build.sh -U) at least 57 once and install sets, or download comp.{tar.xz,tgz} from the 58 daily builds and install that before doing the next in-place build. 59 6020191001: 61 GCC 8.3 was imported. Builds of src/tools/gcc may fail if 62 old builds with GCC 7 output now uses GCC 8. Clean this 63 directory, and also clean src/external/gpl3/gcc. 64 6520190903: 66 Files with names that coincide with existing files' names on 67 case-insensitive file systems were inadvertently committed, for 68 radeon GPU firmware. We cannot mark these as obsolete for 69 postinstall to fix, so if you updated src since 2019-08-26, and 70 ran build.sh distribution or ran build.sh release, you must 71 manually delete the following files in your DESTDIR (which is 72 usually $OBJDIR/destir.$ARCH), or from / if you have installed 73 them: 74 75 /libdata/firmware/radeon/bonaire_ce.bin 76 /libdata/firmware/radeon/bonaire_mc.bin 77 /libdata/firmware/radeon/bonaire_me.bin 78 /libdata/firmware/radeon/bonaire_mec.bin 79 /libdata/firmware/radeon/bonaire_pfp.bin 80 /libdata/firmware/radeon/bonaire_rlc.bin 81 /libdata/firmware/radeon/bonaire_sdma.bin 82 /libdata/firmware/radeon/bonaire_smc.bin 83 /libdata/firmware/radeon/bonaire_uvd.bin 84 /libdata/firmware/radeon/hainan_ce.bin 85 /libdata/firmware/radeon/hainan_mc.bin 86 /libdata/firmware/radeon/hainan_me.bin 87 /libdata/firmware/radeon/hainan_pfp.bin 88 /libdata/firmware/radeon/hainan_rlc.bin 89 /libdata/firmware/radeon/hainan_smc.bin 90 /libdata/firmware/radeon/hawaii_ce.bin 91 /libdata/firmware/radeon/hawaii_mc.bin 92 /libdata/firmware/radeon/hawaii_me.bin 93 /libdata/firmware/radeon/hawaii_mec.bin 94 /libdata/firmware/radeon/hawaii_pfp.bin 95 /libdata/firmware/radeon/hawaii_rlc.bin 96 /libdata/firmware/radeon/hawaii_sdma.bin 97 /libdata/firmware/radeon/hawaii_smc.bin 98 /libdata/firmware/radeon/kabini_ce.bin 99 /libdata/firmware/radeon/kabini_me.bin 100 /libdata/firmware/radeon/kabini_mec.bin 101 /libdata/firmware/radeon/kabini_pfp.bin 102 /libdata/firmware/radeon/kabini_rlc.bin 103 /libdata/firmware/radeon/kabini_sdma.bin 104 /libdata/firmware/radeon/kaveri_ce.bin 105 /libdata/firmware/radeon/kaveri_me.bin 106 /libdata/firmware/radeon/kaveri_mec.bin 107 /libdata/firmware/radeon/kaveri_mec2.bin 108 /libdata/firmware/radeon/kaveri_pfp.bin 109 /libdata/firmware/radeon/kaveri_rlc.bin 110 /libdata/firmware/radeon/kaveri_sdma.bin 111 /libdata/firmware/radeon/mullins_ce.bin 112 /libdata/firmware/radeon/mullins_me.bin 113 /libdata/firmware/radeon/mullins_mec.bin 114 /libdata/firmware/radeon/mullins_pfp.bin 115 /libdata/firmware/radeon/mullins_rlc.bin 116 /libdata/firmware/radeon/mullins_sdma.bin 117 /libdata/firmware/radeon/oland_ce.bin 118 /libdata/firmware/radeon/oland_mc.bin 119 /libdata/firmware/radeon/oland_me.bin 120 /libdata/firmware/radeon/oland_pfp.bin 121 /libdata/firmware/radeon/oland_rlc.bin 122 /libdata/firmware/radeon/oland_smc.bin 123 /libdata/firmware/radeon/pitcairn_ce.bin 124 /libdata/firmware/radeon/pitcairn_mc.bin 125 /libdata/firmware/radeon/pitcairn_me.bin 126 /libdata/firmware/radeon/pitcairn_pfp.bin 127 /libdata/firmware/radeon/pitcairn_rlc.bin 128 /libdata/firmware/radeon/pitcairn_smc.bin 129 /libdata/firmware/radeon/tahiti_ce.bin 130 /libdata/firmware/radeon/tahiti_mc.bin 131 /libdata/firmware/radeon/tahiti_me.bin 132 /libdata/firmware/radeon/tahiti_pfp.bin 133 /libdata/firmware/radeon/tahiti_rlc.bin 134 /libdata/firmware/radeon/tahiti_smc.bin 135 /libdata/firmware/radeon/verde_ce.bin 136 /libdata/firmware/radeon/verde_mc.bin 137 /libdata/firmware/radeon/verde_me.bin 138 /libdata/firmware/radeon/verde_pfp.bin 139 /libdata/firmware/radeon/verde_rlc.bin 140 /libdata/firmware/radeon/verde_smc.bin 141 142 We will re-import these radeon firmware images another way 143 later. 144 14520190727: 146 The uefi bootloader has gained tftp support and needs a clean 147 build. If you do update builds, manually clean its object 148 directory by something like: 149 cd sys/arch/i386/stand/efiboot && make clean 150 15120190723: 152 The jemalloc allocator in libc is now build without extended 153 debugging (for performance reasons). In update builds make sure 154 to rebuild it completly, by removing all affected object files, 155 including compat builds, something like: 156 cd /usr/obj && find . -type d -name jemalloc|xargs rm -rf 157 15820190207: 159 GCC 7 switched for many ports. Update builds are likely to fail. 160 16120180924: 162 A newer OpenSSL version has been imported. If you are doing 163 update builds, make sure to remove all old obj dirs, like: 164 cd /usr/obj && find . -type d -name openssl | xargs rm -rf 165 16620180717: 167 On aarch64 int64_t and related types have changed from long long 168 to long. This requires recompiling all C++ binaries. 169 17020180713: 171 On amd64 and i386 static binaries are now build position 172 independend. This requires recompilation of all object 173 files used to create the crunched /rescue binary. 174 Clean the rescue directory in your obj directory before 175 doing an update build, otherwise linking will fail. 176 17720180414: 178 Existing binutils was migrated to binutils.old. Manual 179 removal of tools/binutils objects directory may be required 180 to fix tools build failure. 181 18220180311: 183 bdftopcf was updated and may need cleaning in the 184 src/external/mit/xorg/tools/bdftopcf subdirectory if there are 185 link errors. 186 18720180212: 188 between OpenSSL and GCC updates, many things may fail to build. 189 any failure that looks like GCC or openssl is best handled by 190 a clean destdir and objdir. Full cleandir and destdir deletion 191 is recommended if build failures occur. 192 19320171225: 194 removal of the vadvise syscall requires manual removal of all 195 associated files from the libc build object directory (including 196 the .depend files) - a command like: 197 cd $OBJ && find . -type d -name libc | xargs rm -rf 198 For architectures that support multiple "compat" binary targets, 199 you'll need to cleanup both the regular libc directory and the 200 compat ones (the above command will do that). 201 20220171010: 203 a change to the build structure of external/bsd/acpica/bin/iasl 204 means that its objdir (or *.d and .depend at least) might need 205 to be manually removed - or a build done once without -u. 206 20720170822: 208 a new version of GMP has been imported and probably 209 will break parts of builds related to themselves or GCC, both 210 in the tools and the native section. Remove all GCC, GMP, MPFR 211 and MPC objdirs or build once without -u. 212 21320170816: 214 a new version of MPFR and MPC have been imported and probably 215 will break parts of builds related to themselves or GCC, both 216 in the tools and the native section. Remove all GCC, GMP, MPFR 217 and MPC objdirs or build once without -u. 218 21920170402: 220 a new version of dhcpcd has been imported, which does not support 221 update builds from the previous version. Remove your 222 external/bsd/dhcpcd object dir or build once without -u. 223 22420170211: 225 a new terminfo database has been imported. 226 The structure of it has changed slightly from prior versions and 227 an updated tic tool is required. 228 If you build.sh, don't use -u 229 23020170207: 231 various arch dependent libc/exect.S files were removed 232 Either remove the obj directories (lib/libc and compat/amd64/i386/lib 233 if it exists) or do a clean build. 234 (This is a bug in the make system, it should be corrected without 235 human intervention, but isn't.) 236 23720170104: 238 xinput build options have changed. 239 Remove the obj directory (external/mit/xorg/bin/xinput) 240 if you build.sh -u 241 24220170103: 243 a new version of flex has been imported. 244 Remove the file from obj (external/bsd/flex) 245 if you build.sh -u 246 24720161014: 248 a new version of OpenSSL has been imported. 249 Remove the files from obj (crypto/external/bsd/openssl) 250 if you build.sh -u 251 25220161009: 253 a new version of dhcpcd has been imported with slightly changed 254 build infrastructure. When doing a build.sh -u this requires 255 pruning the external/bsd/dhcpcd objdir. 256 25720160914: 258 i386, amd64, shark, ofppc and macppc have joined shark and x68k 259 ports in using xorg-server 1.18. This requires a clean destdir 260 and a clean objdir. 261 26220160527: 263 i386 needs a full cleandir or objdir deletion because PIE has 264 been enabled. (see the amd64 entry two down for further info) 265 26620160418: 267 libedit needs manual removal of all autogenerated files since 268 some of them are not autogenerated anymore. Remember that there 269 might be two copies of libedit if your platform builds "compat". 270 27120160410: 272 amd64 needs full "make cleandir" or deletion of objdir now that 273 PIE has been enabled for amd64. PIE, or position-independent 274 executables, means all code, including executables and not just 275 shared libraries, is position-independent and hence able to be 276 relocated by ASLR, address space layout randomization. 277 278 The change was made in Makefile variables for compiler and 279 linker flags, for which make(1) does not record dependencies, 280 hence it is unable to detect that all .o files need rebuilding. 281 282 Partial rebuilds with some modified source files will likely 283 fail when linking executables, since the linker refuses to mix 284 position-independent code with position-dependent code in 285 position-independent executables: 286 287 .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC 288 28920160401: 290 Ports switching to GCC 5.3 will need a full "make cleandir". 291 Some people have found that cleandir is not sufficient, so if 292 in doubt delete the entire object directory tree for gcc. 293 29420160306: 295 NetBSD's regexp implementation is now part of libnbcompat. 296 Nblex, nbm4, nbpax, nbsed use it and they may crash on 297 non-NetBSD hosts if linked with stale object files produced 298 while they included a non-NetBSD regex.h. 299 In any case, you should "make cleandir" at least these tools 300 before updating your toolchain. 301 30220160125: 303 Dtrace has been enabled by default on some architectures. 304 When doing an update build, make sure to clean the etc/mtree 305 object directory before starting the build - otherwise the 306 needed directories in destdir will not be created. 307 An easy way to do this is: 308 cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir 309 31020150818: 311 New acpica requires "make cleandir" in src/external/bsd/acpica 312 again. 313 31420150413: 315 New acpica requires "make cleandir" and reinstalling yacc 316 in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and 317 also "make cleandir" in /usr/src/external/bsd/acpica. 318 31920150404: 320 Lint changes require a full rebuild of the tool, so make 321 sure to build without -u option to build.sh, or manually 322 do a make cleandir in src/tools/lint1 and 323 src/usr.bin/xlint. 324 32520150310: 326 Improvements to openssl for arm mean that update builds of 327 the openssl libraries will fail. A make cleandir in 328 external/bsd/openssl/lib is needed 329 33020141026: 331 A mishap during the import of pppd may cause your corruption 332 in your cvs directory if you happened to do a cvs update 333 during a short period of time. To fix, just remove the 334 directory src/external/bsd/ppp/dist/pppd completely 335 and let cvs restore it on next update. 336 33720140721: 338 The src/external/mit/lua/src directory was accidentally created 339 and then deleted in the CVS repository. If you get errors like 340 341 cvs [update aborted]: cannot open directory 342 /cvsroot/src/external/mit/lua/src: No such file or directory 343 344 then delete your local copy of that directory tree and try again. 345 34620140530: 347 ARM eABI switched to DWARF based exception handling. This requires 348 rebuilding all C++ code. It is strongly advised to do a clean build. 349 35020140131: 351 The new compiler_rt/libc integration moved a few things. It is strongly 352 advised to do a clean build. At least lib/libc, the compat version(s) 353 of libc, libkern, rump and the kernels need to be cleaned. 354 35520131227: 356 1. The new ntpd runs in a restricted mode to prevent amplification 357 attacks. If you need ntpdc to work you need to explicitly enable 358 mode7 in your config file. Make sure you put the necessary restrict 359 statements to avoid being exposed. 360 2. strncat has moved from lib/libc to common/lib/libc; you might need 361 to make clean in libc 362 36320131129: 364 The GMP sources were updated, and builds will likely fail without 365 cleaning their build trees for both tools and in-tree, like below. 366 36720131128: 368 The MPC and MPFR sources were updated, and builds may require their 369 tools and in-tree directories cleaned for successful updates. 370 37120130605: 372 The kernel option FAST_IPSEC no longer exists, it's been renamed 373 to IPSEC (and the older IPSEC version removed). 374 37520130605: 376 Previous freetype installations eroneously installed private 377 header files. If you are building against a non-empty $DESTDIR, 378 please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/. 379 38020130531: 381 The xdm update may cause build failure due to xdm.man being 382 in the obj tree. Make sure to ensure any like this: 383 nbmake: nbmake: don't know how to make xdm.man. Stop 384 is fixed by deleting the xdm.man in the obj tree. 385 38620130530: 387 Updates of many xsrc packages will leave old .pc files around. 388 Best to clean out the xsrc objdir entirely before rebuilds. 389 39020130301: 391 The removal of netiso requires manual removal of /usr/include/netiso 392 prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump} 393 39420120726: 395 The update of OpenSSL requires cleaning both the OpenSSL build 396 directory and DESTDIR. *Even non-update builds require cleaning 397 DESTDIR.* Builds done without taking these steps may fail, or in 398 some cases may succeed and install broken OpenSSL libraries that 399 cause third-party software to link incorrectly and/or crash. 400 40120120507: 402 The database schema for makemandb was changed. You will 403 need to update the database using 'makemandb -f' or wait 404 for the next weekly run to fix it. 405 40620120319: 407 sys/conf/Makefile.kern.inc has been modified to adjust the 408 size of db_symtab automatically. You need to update dbsym in 409 your $TOOLDIR to build kernels with options SYMTAB_SPACE. If 410 you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your 411 mk.conf. 412 41320120216: 414 Default for MKCATPAGES changed to NO. Update builds will fail 415 unless DESTDIR is cleaned manually. If you built between 20120207 416 and 20120216, daily and weekly could have created an unreadable 417 /var/db/man.db index for apropos. Running makemandb -f or 418 the next run of weekly will fix it. 419 42020111227: 421 If you built between 20111225 and 20111227 you need to remove 422 /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the 423 bump has been reverted. 424 42520111125: 426 The "rnd" pseudodevice has been added to sys/conf/std, which 427 means it should no longer be explicitly listed in kernel 428 configuration files. The line "pseudo-device rnd" should be 429 removed from any custom kernel config files users may have. 430 43120111119: 432 A problem with the datastructures used by the rndctl(8) 433 utility (pointers in datastructures in an array, making 32->64 434 bit compatibility very painful) has been fixed in a 435 non-backwards-compatible way. If you replace your kernel, 436 replace your rndctl executable too. 437 43820111001: 439 the prop_*_send_syscall() functions from proplib(3) have been 440 changed and their new version is not backward compatible with the old 441 one. So ensure that all consumers of these functions (currently: 442 quota2 code and its tests) are updated together with the new lib. 443 44420110817: 445 sparc has been changed to use GCC 4.5.3, so any objdir or 446 DESTDIR for them should be deleted before updating. 447 44820110806: 449 i386 and amd64 have been changed to use GCC 4.5.3, so any 450 objdir or DESTDIR for them should be deleted before updating. 451 45220110805: 453 The update to GCC 4.5.3 requires a non-trivial portion of 454 the tree to be cleaned. Best to delete both objdir and 455 DESTDIR before running this update. So far, only the 456 sparc64, mips and powerpc platforms have changed. 457 45820110803: 459 The layout of external/public-domain/xz has changed. To do an 460 update build you will have to remove the contents of the OBJDIR 461 for external/public-domain/xz/bin by hand as the xz entry there 462 is now a directory. 463 46420110410: 465 The configuration of src/tools/gcc has changed. To do an 466 update build you have to clean both tools/binutils and 467 tools/gcc by hand. 468 46920110328: 470 Building the Xorg binary was moved into a subdirectory to fix 471 ordering issues with "make all". It may be necessary to remove 472 the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86 473 if your update build fails, as the "Xorg" entry there is now a 474 directory. 475 47620110121: 477 Assembler files no longer use -traditional-cpp. This can break 478 the build of individual parts of the tree. This is handled 479 correctly by build.sh. Manual builds have to update /usr/share/mk 480 and re-run config(1) for any kernel configurations as needed. 481 48220101217: 483 The tcpdump(8) program was changed to drop privileges and chroot(2) 484 by default. It may be necessary to manually update passwd(5) and 485 group(5) in order to make the program work with existing setups. 486 48720101125: 488 The latest changes to setenv(3) dissallow setting environment 489 variables with names that contain '='. Revision 1.18 of env.c 490 assumed that this was allowed. Installing a new libc with an 491 old copy of /usr/bin/env causes env x=1 printenv | grep x= to 492 break which affects the autoconf tests for dependency finding, 493 so building gcc will end up printing: 494 checking dependency style of gcc... none 495 configure: error: no usable dependency style found 496 Fix it by rebuilding and re-installing env. 497 49820101119: 499 Recent Xorg updates in xsrc/external/mit/ may cause various build 500 or run-time problems. Delete your entire DESTDIR and OBJDIR if you 501 have any build problems with xsrc, or problems with mismatched 502 versions between xorg-server and drivers. 503 50420100604: 505 The update of ATF to 0.9 causes old tests written in shell to fail 506 unless they are rebuilt. If you are building with MKUPDATE=yes, 507 you need to clean the src/external/bsd/atf/tests/ and the src/tests/ 508 trees by hand. 509 51020100522: 511 Recent Xorg updates in xsrc/external/mit/ will cause various build 512 problems. Delete your entire DESTDIR and OBJDIR if you have any 513 build problems with xsrc. 514 51520100522: 516 private section of <ctype.h> was splitted, and now mklocale(1) 517 include ctype_local.h, so you have to make cleandir in tools/mklocale. 518 51920100520: 520 The location of the xkb compiled descriptions has changed. Please 521 remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR. 522 52320100222: 524 The shared objects file extension has been changed from .so to 525 .pico, in order to avoid conflicts with shared libraries names 526 libXX.so. All now stale regular .so files can be removed from 527 your object directories. 528 52920100204: 530 The termcap database has been removed from the sources, 531 but has not been marked obsolete so it is not removed 532 from the system when upgrading. 533 As such, you will need to remove them from your object 534 and destination directories. 535 53620091101: 537 After updating, it may be necessary to make the 'cleandir' 538 target in src/tools/yacc/ and in src/usr.bin/yacc/ before a 539 'build.sh -u tools' or 'build.sh -u distribution'. Ditto 540 src/tools/lex/ and src/usr.bin/lex/. 541 54220091001: 543 On amd64 you must rebuild tools (to get the new binutils) 544 before building a kernel, or the build fails on cpufunc.S. 545 54620091001: 547 An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb 548 symlink, failing the build. Delete the link, and the subdir 549 it is in, and retry your build. 550 55120090718: 552 libc build changed so that strchr() provides the extra entry 553 point for index(). Update build of libc.a (and libc_pic.a) 554 may fail because the archive contains the unwanted index.o. 555 (Similarly for strrchr() and rindex().) 556 55720090709: 558 Native Xorg was upgraded again. Builds will probably fail again 559 without a clean objdir, at least for src/external/mit/xorg. 560 56120090616: 562 Native Xorg was upgraded. Builds will need a clean objdir for 563 src/external/mit/xorg. Upgrading a system from sets will not 564 work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc 565 subdirectory has been changed into a file, and this needs to 566 be manually "rm -r"'ed before installing xbase.tgz. 567 56820090501: 569 Several new functions were added to string.h/libc, and this 570 can cause autoconf problems during the tool build for people 571 who fail to clean out their tools objects properly. If you 572 note messages about stpcpy, stpncpy or strnlen accompanying a 573 failure during the tool build, clean out all your tools 574 objects and start again. 575 57620090325: 577 The i386 port was switched to i486 default toolchain. This requires 578 cleaning your src/tools directory and $TOOLDIR and rebuilding them. 579 58020090126: 581 The __posix_fadvise50 system call changed assembly stub type. You 582 need to 'rm -f __posix_fadvise50.*' in the libc build directory 583 to avoid using the old assembly stub. 584 58520090202: 586 pkg_install now depends on the pkgdb cache for automatic conflict 587 detection. It is recommented to rebuild the cache with 588 ``pkg_admin rebuild''. 589 59020090110: 591 time_t and dev_t have been bumped to 64 bit quantities. To upgrade: 592 1. Make sure your kernel has COMPAT_50 in it. Build and install. 593 This is needed even in the MODULAR kernel because there is 594 conditionally compiled code in rtsock.c. 595 2. make sure build.sh completes and the binaries in a chroot work 596 before installing. 597 3. If you don't use build.sh and you build directly to root, and 598 your build breaks in the middle, don't despair. Make sure headers 599 are installed properly, and start building libraries first libc 600 and libutil, install them and then continue building all the 601 libraries in src/lib and src/gnu/lib and install them. Once 602 the new libraries are installed, you can restart the build. 603 4. If you compile packages and you notice link time warnings, 604 rebuild the required packages to update their shared libraries. 605 Any package you rebuild will require rebuilding all the packages 606 that depend on it. 607 5. Next time you run pwd_mkdb with the new binary, the file 608 will be upgraded and it will not be backwards compatible. 609 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see 610 lastlogx(5)) have been versioned, and there is a heuristic 611 for utmp. You are better off removing the old files after 612 upgrading. The automated clearing of /var/run during 613 boot, and the automated rotating of files in /var/log by 614 newsyslog(8), may mean that you do not have to remove the 615 files manually. 616 7. The optional accounting file (/var/account/acct, see 617 accton(8)) has not been versioned, and will need to be 618 removed. The automatic rotation of the accounting file by 619 /etc/daily limits the bad consequences of failure to remove 620 the file. 621 8. Application software that writes time_t to binary files on 622 disk will break or need attention. Most notably: if you are 623 using PostgreSQL < 8.4, you need to dump your databases, 624 rebuild PostgreSQL with the new time_t, then restore. 625 62620081219: 627 config(1) has been updated, and one of the files it creates - 628 swapnetbsd.o - has changed format. You need to rebuild config 629 (done automatically by build.sh) and then you need to rerun 630 config on all kernel configuration files before rebuilding those 631 kernels. 632 63320081205: 634 If you build with MKX11=no, you should remove /etc/rc.d/xdm and 635 /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc 636 set and will appear as extra files for MKX11=no update builds. 637 63820081122: 639 On i386, various kernel options(4) in GENERIC including 640 file systems have been disabled and moved into kernel modules. 641 Before trying a new GENERIC kernel, you have to prepare the 642 following files as well as a new GENERIC kernel: 643 644 - build and install kernel modules from src/sys/modules 645 646 - install the latest bootloader, which will load a module 647 for the file system from which the kernel is loaded automatically 648 649 If you have to load your kernel from a file system which is not of 650 the same type as the root file system, you have to load the necessary 651 file system module manually on the boot prompt or in the boot.cfg file. 652 65320080827: 654 If you built and installed a libc from sources between 655 2008/08/20 and 2008/08/26 you got a broken strtouq(3) 656 which results in false errors reported by lint(1). 657 Since this breaks the libc build itself, manual help is 658 needed -- lint must be disabled temporarily, e.g.: 659 $ (cd lib/libc && make MKLINT=no dependall install) 660 66120080813: 662 MKDEBUG build was broken because the .depend files did not know 663 about .go files. You need to remove all .depend files and rebuild. 664 66520080802: 666 A regression in binary compatibility for pthread_mutex_t has 667 been fixed. Unfortunately, the price is breaking compatibility 668 for -current. 669 670 Threaded programs (using libpthread) and C++ programs (using 671 libstdc++) compiled after 20070907 and before 20080802 need to 672 be recompiled. 673 674 One way to find affected pkgsrc packages: 675 676 $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO 677 $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO 678 67920080731: 680 WAPBL (metadata journaling support) has been added, but at this 681 time isn't backwards compatible with pre-WAPBL aware kernels 682 and userland (fsck_ffs in particular). Please make sure you 683 don't use a journaled filesystem with an older kernel/userland, 684 especially an uncleanly mounted journaled filesystem. WAPBL 685 also requires the super block to be in the UFS2 format. You 686 can use fsck_ffs -c 4 to update the superblock format. 687 68820080721: 689 Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR 690 isn't defined. 691 69220080531: 693 The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed 694 from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8) 695 utility needs to be rebuilt and reinstalled as older binaries 696 won't work correctly. The following sequence of commands: 697 698 $ (cd sys/sys/ && nbmake-$arch includes) 699 $ (cd sbin/drvctl/ && nbmake-$arch clean) 700 $ (cd sbin/drvctl/ && nbmake-$arch all) 701 702 leaves new drvctl utility in sbin/drvctl build directory. 703 70420080503: 705 The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE. 706 70720080521: 708 For a while, unprivileged UPDATE builds would fail to 709 succeed at the checkflist stage, complaining that 710 ${DESTDIR}/stand/<arch>/ did not exist. A fix for this 711 problem was committed to share/mk/bsd.kmodule.mk, revision 1.9. 712 If you already hit this problem, update the .mk file, 713 remove ${DESTDIR}/stand/<arch>, and re-run the build. 714 71520080303: 716 Linker warnings are now fatal if $WARNS>0. 717 71820080126: 719 The posix_fadvise system call has been changed from an assembly 720 stub, to a c file that calls an assembly stub. You need to 721 'rm -f posix_fadvise.* .depend' in the libc build directory to 722 avoid using the old assembly stub. 723 72420071209: 725 The acpiec(4) driver has been split into two attachments. If you 726 get ACPI errors before the attachment, please update your kernel 727 configuration file appropriately or see GENERIC for more details. 728 72920071115: 730 The it(4) driver has been renamed to itesio(4) and the old port 731 argument specified in the kernel configuration file is not valid 732 anymore. The itesio(4) driver now uses the Super I/O address port 733 rather than the EC address port. Please update your kernel 734 configuration file appropriately or see GENERIC for more details. 735 73620071028: 737 The pccons(4) driver has been removed from the NetBSD/shark port. 738 You need to update any custom kernel configuration file you have 739 to remove any references to pccons (which includes removing the 740 now useless XSERVER option) and replace them with the correct 741 entries for the wscons driver. See the GENERIC configuration file 742 for more details. 743 74420070913: 745 A latent bug in dhclient/dhcpd that caused it to be unable to 746 enumerate interfaces was fixed. The bug began to cause 747 problems after 20070911 when the kernel's SIOCGIFCONF 748 implementation was repaired. From 20070529 to 20070911 racoon 749 could not enumerate interfaces. (These are noted because 750 normal kernel/userspace version matching hygiene is not 751 sufficient to avoid this problem.) Ensure that both kernel 752 and userland are from after 20070913. 753 75420070703: 755 nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It 756 calls the target-specific strip program, and the logic to pass 757 down STRIP from make has been removed. This requires a 758 re-installation of tools. 759 76020070422: 761 The way OS emulations lookup filenames inside the emulation root 762 has been changed. Rather than modify the pathname (and copy back 763 to userspace) namei() and lookup() directly check the emulation 764 root. One side effect is that absolute symlinks inside the emulated 765 root file system will be relative to that file system - unless they 766 start /../ this is useful when the emulated root is a real install 767 that has such links. 768 This might affect symlinks that have been added to reference outside 769 the emulated root. 770 77120070412: 772 The pckbc driver on sgimips IP32 has been removed. Use macekbc 773 instead. See the GENERIC32_IP3x kernel configuration for an 774 example. 775 77620070319: 777 src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so 778 on many platforms due to incorrect flags settings. If you 779 updated and built after about 20070315, do "nbmake-$arch 780 cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a 781 rebuild of object files that might have been built 782 incorrectly, and ensure that you have at least 783 src/lib/libc/Makefile 1.130. 784 78520070210: 786 src/sys/sys/{sa.h,savar.h} were removed. 787 find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \ 788 | xargs egrep -l '/sa.h|/savar.h' | xargs rm 789 will allow dependencies on those files to get get rebuilt 790 79120070209: 792 The threading model was changed when the newlock2 branch 793 was merged to NetBSD-current. If you boot with a new 794 kernel (version 4.99.10), then you also need a new pthread 795 library (/usr/lib/libpthread.so.0.7). If you boot with 796 an old kernel, then you need the old pthread library 797 (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and 798 the pthread library in sync, old threaded applications should 799 continue to work with an old or new kernel. Note that named(8) 800 is the only threaded application in the base system. 801 80220061214: 803 Following the move of string_to_flags() and flags_to_string() 804 from the bin/ls/ sources to libutil, users doing UPDATE builds 805 will need to do a "make cleandir" in 806 tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/, 807 bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/, 808 usr.bin/xinstall/, libexec/ftpd/, rescue/, as well 809 as the installation images in distrib/ 810 in order to excise stale references to the old stat_flags.h header 811 file in the ls sources -- stat_flags.h has been removed. 812 81320061108: 814 The configure script used in the src/tools/gcc compiler has been 815 changed to indicate that our libc has ssp support built-in and 816 does not depend on -lssp and -lssp-nonshared. You'll need to 817 make clean in src/tools/gcc first to rebuild the compiler. 818 81920061009: 820 The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer 821 available. Use net.inet{,6}.tcp{,6}.congctl.selected instead. 822 82320060814: 824 The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been 825 withdrawn. Use vidcvideo and pckbd instead. See the GENERIC 826 kernel configuration for an example. X servers from the last 827 few years should cope. 828 82920060703: 830 MPACPI is no more. We always configure PCI interrupts using ACPI 831 if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed 832 to ACPI_SCANPCI. Thanks to work from fvdl. 833 83420060627: 835 socket(2) has changed, and its system call has been versioned. 836 For userlands with the old version of socket(2), make sure that 837 your kernel has 'options COMPAT_30' set, or else 'bad system call' 838 errors will result. 839 840Hints for a more successful build: 841^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 842 Use build.sh, but do not use its "expert mode": 843 This will automatically build the tools in the 844 correct order, and it will keep the tools and the 845 new build products from interfering with the running 846 system. This will allow you to ignore most of the 847 other advice in this file. 848 Build a new kernel first: 849 This makes sure that any new system calls or features 850 expected by the new userland will be present. This 851 helps to avoid critical errors when upgrading. 852 Use object directories: 853 This helps to keep stale object 854 files from polluting the build if a Makefile "forgets" 855 about one. It also makes it easier to clean up after 856 a build. It's also necessary if you want to use the 857 same source tree for multiple machines. 858 To use object directories with build.sh: 859 a) invoke build.sh with the "-M" or "-O" options. 860 To use object directories without using build.sh: 861 a) cd /usr/src ; make cleandir 862 b) Add "OBJMACHINE=yes" to /etc/mk.conf 863 c) Add "MKOBJDIRS=yes" to /etc/mk.conf 864 d) cd /usr/src ; make build 865 Note that running "make obj" in a directory will create 866 in obj.$MACHINE directory. 867 Build to a DESTDIR: 868 This helps to keep old installed files (especially libraries) 869 from interfering with the new build. 870 To build to a DESTDIR with build.sh, use the "-D" option. 871 To build to a DESTDIR without using build.sh, set the DESTDIR 872 environment variable before running make build. It should be 873 set to the pathname of an initially empty directory. 874 Problems: if you do not use build.sh, you might need to 875 update critical utilities without using DESTDIR since 876 nothing is executed from what is installed in DESTDIR. 877 (See critical utils, below.) 878 Build often: 879 This keeps critical utilities current enough to not choke 880 on any other part of the source tree that depends on up to 881 date functionality. If you use build.sh, you should not have 882 this problem. 883 884What to do if things don't work: 885^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 886When things don't work there are usually a few things that commonly 887should be done. 888 1) make includes 889 This should be done automatically by make build. 890 2) cd share/mk && make install 891 Again, automatically done by make build. 892 893Failsafe rebuild of a small part of the tree: 894^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 895To make sure you rebuild something correctly you want to do 896something like the following: 897 1) Make sure the includes and .mk files are up to date. 898 2) Make sure any program used to build the particular 899 utility is up to date. (yacc, lex, etc...) 900 3) cd ...path/to/util... 901 make cleandir 902 rm ...all obj directories... 903 make cleandir # yes, again 904 make obj 905 make depend && make 906 907Failsafe rebuild of the entire tree: 908^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 909If you really want to make sure the source tree is clean and 910ready for a build try the following. Note that sourcing /etc/mk.conf 911(a make(1) Makefile) in this manner is not right, and will not work 912for anyone who uses any make(1) features in /etc/mk.conf. 913 914---cut here--- 915#!/bin/sh 916. /etc/mk.conf 917 918if [ -z $NETBSDSRCDIR ] ; then 919 NETBSDSRCDIR=/usr/src 920fi 921if [ \! -d $NETBSDSRCDIR ] ; then 922 echo Unable to find sources 923 exit 1 924fi 925find $NETBSDSRCDIR -name \*.o -o -name obj.\* -o -name obj -exec rm \{\} \; 926 927if [ -z $BSDOBJDIR ] ; then 928 BSDOBJDIR=/usr/obj 929fi 930if [ -d $BSDOBJDIR ] ; then 931 rm -rf $BSDOBJDIR 932fi 933 934cd $NETBSDSRCDIR && make cleandir 935 936---cut here--- 937 938Critical utilities: 939^^^^^^^^^^^^^^^^^^^ 940 usr.bin/compile_et 941 usr.bin/make 942 usr.bin/yacc 943 usr.bin/lex 944 usr.bin/xlint 945 usr.bin/config 946 947Other problems and possible solutions: 948^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 949Symptom:Complaints involving a Makefile. 950Fix: Rebuild usr.bin/make: 951 cd usr.bin/make && make && make install 952 Or, a failsafe method if that doesn't work: 953 cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin 954 955Fix: Make sure .mk files are up to date. 956 cd share/mk && make install 957 958Symptom:Kernel `config' fails to configure any kernel, including GENERIC. 959Fix: Rebuild usr.bin/config 960 961Symptom: 962Fix: Rebuild usr.bin/yacc 963 964Symptom: 965Fix: Rebuild usr.bin/lex 966 967Symptom: 968Fix: rm /usr/lib/libbfd.a 969 970Symptom:Obsolete intermediate files are used during compilation 971Fix: Try the following sequence of commands in the directory in question. 972 make cleandir; rm `make print-objdir`; make cleandir; make obj 973 (If you built the tree without "make obj" in the past, obsolete files 974 may remain.
