UPDATING revision 1.321
1$NetBSD: UPDATING,v 1.321 2021/09/18 03:05:19 christos 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 2220210917: 23 Changed MNT_ACLS to default to POSIX1e ACLs instead of NFSv4 24 ACLs, to be compatible with FreeBSD. If you are using NFSv4 ACLs 25 and have "acls" in /etc/fstab you'll need to change it to "nfs4acls". 26 2720210711: 28 Updated GMP sources may require cleaning in tools/gmp and/or in 29 external/lgpl3/gmp/lib, particularly if GCC itself does not build. 30 3120210417: 32 GCC 10 was enabled for several platforms. If builds fail in either 33 tools/gcc or external/gpl/gcc, first try cleaning those objects and 34 removing the $DESTDIR/usr/include/g++ subdirectory. 35 3620201230: 37 lint1/ops.c is no longer autogenerated. If this makes the build 38 fail, clean $OBJDIR/tools/*lint* and $OBJDIR/usr.bin/*xlint*. 39 4020201016: 41 MIPS kernel modules have been disabled until they work. This will 42 turn up in extra files in the DESTDIR, which should be cleaned. 43 4420200925: 45 GNU MPC and MPFR have been updated. At least MPFR needs cleaning 46 in both the tools and external dirs. 47 4820200912: 49 GCC 9 has arrived for Arm and x86 platforms, and will be coming 50 for several more, as will binutils 2.34. Clean as required. 51 5220200907: 53 GCC 9 is coming, and binutils has been updated for MIPS. This 54 probably requires cleaning the tools/binutils. 55 5620200811: 57 GCC updates may require cleaning the objdir. This may occur 58 due to GCC 7.5 update, GCC 8.4 move to gcc.old, or the upcoming 59 GCC 9 upgrade. 60 6120200614: 62 blacklist* has been renamed to blocklist*. postinstall(8) 63 should handle the migration 64 6520200601: 66 Due to a mistake in LIBISPRIVATE handling, .so libraries were 67 created in the build directories and need cleaning. 68 6920200311: 70 GCC 8 ports will need cleaning in src/tools/gcc and 71 src/external/gpl3/gcc due to GCC 8.4 update. 72 7320191118: 74 More architectures were switched to gcc8: 75 i386, ia64 powerpc64, sparc, sparc64, arm 76 The same comments as in 20191022 apply. 77 7820191112: 79 The LLVM update requires a clean rebuild for all architectures using 80 LLVM during the tools build phase (i386, amd64, aarch64). 81 8220191022: 83 Ports amd64 and aarch64 switched to GCC 8.3 by default. 84 In-place ("expert mode", build.sh -E) builds are not supported 85 when going from a GCC 7 userland to GCC 8. Do a regular 86 build to a different DESTDIR (or preferably: build.sh -U) at least 87 once and install sets, or download comp.{tar.xz,tgz} from the 88 daily builds and install that before doing the next in-place build. 89 9020191001: 91 GCC 8.3 was imported. Builds of src/tools/gcc may fail if 92 old builds with GCC 7 output now uses GCC 8. Clean this 93 directory, and also clean src/external/gpl3/gcc. 94 9520190903: 96 Files with names that coincide with existing files' names on 97 case-insensitive file systems were inadvertently committed, for 98 radeon GPU firmware. We cannot mark these as obsolete for 99 postinstall to fix, so if you updated src since 2019-08-26, and 100 ran build.sh distribution or ran build.sh release, you must 101 manually delete the following files in your DESTDIR (which is 102 usually $OBJDIR/destir.$ARCH), or from / if you have installed 103 them: 104 105 /libdata/firmware/radeon/bonaire_ce.bin 106 /libdata/firmware/radeon/bonaire_mc.bin 107 /libdata/firmware/radeon/bonaire_me.bin 108 /libdata/firmware/radeon/bonaire_mec.bin 109 /libdata/firmware/radeon/bonaire_pfp.bin 110 /libdata/firmware/radeon/bonaire_rlc.bin 111 /libdata/firmware/radeon/bonaire_sdma.bin 112 /libdata/firmware/radeon/bonaire_smc.bin 113 /libdata/firmware/radeon/bonaire_uvd.bin 114 /libdata/firmware/radeon/hainan_ce.bin 115 /libdata/firmware/radeon/hainan_mc.bin 116 /libdata/firmware/radeon/hainan_me.bin 117 /libdata/firmware/radeon/hainan_pfp.bin 118 /libdata/firmware/radeon/hainan_rlc.bin 119 /libdata/firmware/radeon/hainan_smc.bin 120 /libdata/firmware/radeon/hawaii_ce.bin 121 /libdata/firmware/radeon/hawaii_mc.bin 122 /libdata/firmware/radeon/hawaii_me.bin 123 /libdata/firmware/radeon/hawaii_mec.bin 124 /libdata/firmware/radeon/hawaii_pfp.bin 125 /libdata/firmware/radeon/hawaii_rlc.bin 126 /libdata/firmware/radeon/hawaii_sdma.bin 127 /libdata/firmware/radeon/hawaii_smc.bin 128 /libdata/firmware/radeon/kabini_ce.bin 129 /libdata/firmware/radeon/kabini_me.bin 130 /libdata/firmware/radeon/kabini_mec.bin 131 /libdata/firmware/radeon/kabini_pfp.bin 132 /libdata/firmware/radeon/kabini_rlc.bin 133 /libdata/firmware/radeon/kabini_sdma.bin 134 /libdata/firmware/radeon/kaveri_ce.bin 135 /libdata/firmware/radeon/kaveri_me.bin 136 /libdata/firmware/radeon/kaveri_mec.bin 137 /libdata/firmware/radeon/kaveri_mec2.bin 138 /libdata/firmware/radeon/kaveri_pfp.bin 139 /libdata/firmware/radeon/kaveri_rlc.bin 140 /libdata/firmware/radeon/kaveri_sdma.bin 141 /libdata/firmware/radeon/mullins_ce.bin 142 /libdata/firmware/radeon/mullins_me.bin 143 /libdata/firmware/radeon/mullins_mec.bin 144 /libdata/firmware/radeon/mullins_pfp.bin 145 /libdata/firmware/radeon/mullins_rlc.bin 146 /libdata/firmware/radeon/mullins_sdma.bin 147 /libdata/firmware/radeon/oland_ce.bin 148 /libdata/firmware/radeon/oland_mc.bin 149 /libdata/firmware/radeon/oland_me.bin 150 /libdata/firmware/radeon/oland_pfp.bin 151 /libdata/firmware/radeon/oland_rlc.bin 152 /libdata/firmware/radeon/oland_smc.bin 153 /libdata/firmware/radeon/pitcairn_ce.bin 154 /libdata/firmware/radeon/pitcairn_mc.bin 155 /libdata/firmware/radeon/pitcairn_me.bin 156 /libdata/firmware/radeon/pitcairn_pfp.bin 157 /libdata/firmware/radeon/pitcairn_rlc.bin 158 /libdata/firmware/radeon/pitcairn_smc.bin 159 /libdata/firmware/radeon/tahiti_ce.bin 160 /libdata/firmware/radeon/tahiti_mc.bin 161 /libdata/firmware/radeon/tahiti_me.bin 162 /libdata/firmware/radeon/tahiti_pfp.bin 163 /libdata/firmware/radeon/tahiti_rlc.bin 164 /libdata/firmware/radeon/tahiti_smc.bin 165 /libdata/firmware/radeon/verde_ce.bin 166 /libdata/firmware/radeon/verde_mc.bin 167 /libdata/firmware/radeon/verde_me.bin 168 /libdata/firmware/radeon/verde_pfp.bin 169 /libdata/firmware/radeon/verde_rlc.bin 170 /libdata/firmware/radeon/verde_smc.bin 171 172 We will re-import these radeon firmware images another way 173 later. 174 17520190727: 176 The uefi bootloader has gained tftp support and needs a clean 177 build. If you do update builds, manually clean its object 178 directory by something like: 179 cd sys/arch/i386/stand/efiboot && make clean 180 18120190723: 182 The jemalloc allocator in libc is now build without extended 183 debugging (for performance reasons). In update builds make sure 184 to rebuild it completly, by removing all affected object files, 185 including compat builds, something like: 186 cd /usr/obj && find . -type d -name jemalloc|xargs rm -rf 187 18820190207: 189 GCC 7 switched for many ports. Update builds are likely to fail. 190 19120180924: 192 A newer OpenSSL version has been imported. If you are doing 193 update builds, make sure to remove all old obj dirs, like: 194 cd /usr/obj && find . -type d -name openssl | xargs rm -rf 195 19620180717: 197 On aarch64 int64_t and related types have changed from long long 198 to long. This requires recompiling all C++ binaries. 199 20020180713: 201 On amd64 and i386 static binaries are now build position 202 independend. This requires recompilation of all object 203 files used to create the crunched /rescue binary. 204 Clean the rescue directory in your obj directory before 205 doing an update build, otherwise linking will fail. 206 20720180414: 208 Existing binutils was migrated to binutils.old. Manual 209 removal of tools/binutils objects directory may be required 210 to fix tools build failure. 211 21220180311: 213 bdftopcf was updated and may need cleaning in the 214 src/external/mit/xorg/tools/bdftopcf subdirectory if there are 215 link errors. 216 21720180212: 218 between OpenSSL and GCC updates, many things may fail to build. 219 any failure that looks like GCC or openssl is best handled by 220 a clean destdir and objdir. Full cleandir and destdir deletion 221 is recommended if build failures occur. 222 22320171225: 224 removal of the vadvise syscall requires manual removal of all 225 associated files from the libc build object directory (including 226 the .depend files) - a command like: 227 cd $OBJ && find . -type d -name libc | xargs rm -rf 228 For architectures that support multiple "compat" binary targets, 229 you'll need to cleanup both the regular libc directory and the 230 compat ones (the above command will do that). 231 23220171010: 233 a change to the build structure of external/bsd/acpica/bin/iasl 234 means that its objdir (or *.d and .depend at least) might need 235 to be manually removed - or a build done once without -u. 236 23720170822: 238 a new version of GMP has been imported and probably 239 will break parts of builds related to themselves or GCC, both 240 in the tools and the native section. Remove all GCC, GMP, MPFR 241 and MPC objdirs or build once without -u. 242 24320170816: 244 a new version of MPFR and MPC have been imported and probably 245 will break parts of builds related to themselves or GCC, both 246 in the tools and the native section. Remove all GCC, GMP, MPFR 247 and MPC objdirs or build once without -u. 248 24920170402: 250 a new version of dhcpcd has been imported, which does not support 251 update builds from the previous version. Remove your 252 external/bsd/dhcpcd object dir or build once without -u. 253 25420170211: 255 a new terminfo database has been imported. 256 The structure of it has changed slightly from prior versions and 257 an updated tic tool is required. 258 If you build.sh, don't use -u 259 26020170207: 261 various arch dependent libc/exect.S files were removed 262 Either remove the obj directories (lib/libc and compat/amd64/i386/lib 263 if it exists) or do a clean build. 264 (This is a bug in the make system, it should be corrected without 265 human intervention, but isn't.) 266 26720170104: 268 xinput build options have changed. 269 Remove the obj directory (external/mit/xorg/bin/xinput) 270 if you build.sh -u 271 27220170103: 273 a new version of flex has been imported. 274 Remove the file from obj (external/bsd/flex) 275 if you build.sh -u 276 27720161014: 278 a new version of OpenSSL has been imported. 279 Remove the files from obj (crypto/external/bsd/openssl) 280 if you build.sh -u 281 28220161009: 283 a new version of dhcpcd has been imported with slightly changed 284 build infrastructure. When doing a build.sh -u this requires 285 pruning the external/bsd/dhcpcd objdir. 286 28720160914: 288 i386, amd64, shark, ofppc and macppc have joined shark and x68k 289 ports in using xorg-server 1.18. This requires a clean destdir 290 and a clean objdir. 291 29220160527: 293 i386 needs a full cleandir or objdir deletion because PIE has 294 been enabled. (see the amd64 entry two down for further info) 295 29620160418: 297 libedit needs manual removal of all autogenerated files since 298 some of them are not autogenerated anymore. Remember that there 299 might be two copies of libedit if your platform builds "compat". 300 30120160410: 302 amd64 needs full "make cleandir" or deletion of objdir now that 303 PIE has been enabled for amd64. PIE, or position-independent 304 executables, means all code, including executables and not just 305 shared libraries, is position-independent and hence able to be 306 relocated by ASLR, address space layout randomization. 307 308 The change was made in Makefile variables for compiler and 309 linker flags, for which make(1) does not record dependencies, 310 hence it is unable to detect that all .o files need rebuilding. 311 312 Partial rebuilds with some modified source files will likely 313 fail when linking executables, since the linker refuses to mix 314 position-independent code with position-dependent code in 315 position-independent executables: 316 317 .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC 318 31920160401: 320 Ports switching to GCC 5.3 will need a full "make cleandir". 321 Some people have found that cleandir is not sufficient, so if 322 in doubt delete the entire object directory tree for gcc. 323 32420160306: 325 NetBSD's regexp implementation is now part of libnbcompat. 326 Nblex, nbm4, nbpax, nbsed use it and they may crash on 327 non-NetBSD hosts if linked with stale object files produced 328 while they included a non-NetBSD regex.h. 329 In any case, you should "make cleandir" at least these tools 330 before updating your toolchain. 331 33220160125: 333 Dtrace has been enabled by default on some architectures. 334 When doing an update build, make sure to clean the etc/mtree 335 object directory before starting the build - otherwise the 336 needed directories in destdir will not be created. 337 An easy way to do this is: 338 cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir 339 34020150818: 341 New acpica requires "make cleandir" in src/external/bsd/acpica 342 again. 343 34420150413: 345 New acpica requires "make cleandir" and reinstalling yacc 346 in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and 347 also "make cleandir" in /usr/src/external/bsd/acpica. 348 34920150404: 350 Lint changes require a full rebuild of the tool, so make 351 sure to build without -u option to build.sh, or manually 352 do a make cleandir in src/tools/lint1 and 353 src/usr.bin/xlint. 354 35520150310: 356 Improvements to openssl for arm mean that update builds of 357 the openssl libraries will fail. A make cleandir in 358 external/bsd/openssl/lib is needed 359 36020141026: 361 A mishap during the import of pppd may cause your corruption 362 in your cvs directory if you happened to do a cvs update 363 during a short period of time. To fix, just remove the 364 directory src/external/bsd/ppp/dist/pppd completely 365 and let cvs restore it on next update. 366 36720140721: 368 The src/external/mit/lua/src directory was accidentally created 369 and then deleted in the CVS repository. If you get errors like 370 371 cvs [update aborted]: cannot open directory 372 /cvsroot/src/external/mit/lua/src: No such file or directory 373 374 then delete your local copy of that directory tree and try again. 375 37620140530: 377 ARM eABI switched to DWARF based exception handling. This requires 378 rebuilding all C++ code. It is strongly advised to do a clean build. 379 38020140131: 381 The new compiler_rt/libc integration moved a few things. It is strongly 382 advised to do a clean build. At least lib/libc, the compat version(s) 383 of libc, libkern, rump and the kernels need to be cleaned. 384 38520131227: 386 1. The new ntpd runs in a restricted mode to prevent amplification 387 attacks. If you need ntpdc to work you need to explicitly enable 388 mode7 in your config file. Make sure you put the necessary restrict 389 statements to avoid being exposed. 390 2. strncat has moved from lib/libc to common/lib/libc; you might need 391 to make clean in libc 392 39320131129: 394 The GMP sources were updated, and builds will likely fail without 395 cleaning their build trees for both tools and in-tree, like below. 396 39720131128: 398 The MPC and MPFR sources were updated, and builds may require their 399 tools and in-tree directories cleaned for successful updates. 400 40120130605: 402 The kernel option FAST_IPSEC no longer exists, it's been renamed 403 to IPSEC (and the older IPSEC version removed). 404 40520130605: 406 Previous freetype installations erroneously installed private 407 header files. If you are building against a non-empty $DESTDIR, 408 please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/. 409 41020130531: 411 The xdm update may cause build failure due to xdm.man being 412 in the obj tree. Make sure to ensure any like this: 413 nbmake: nbmake: don't know how to make xdm.man. Stop 414 is fixed by deleting the xdm.man in the obj tree. 415 41620130530: 417 Updates of many xsrc packages will leave old .pc files around. 418 Best to clean out the xsrc objdir entirely before rebuilds. 419 42020130301: 421 The removal of netiso requires manual removal of /usr/include/netiso 422 prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump} 423 42420120726: 425 The update of OpenSSL requires cleaning both the OpenSSL build 426 directory and DESTDIR. *Even non-update builds require cleaning 427 DESTDIR.* Builds done without taking these steps may fail, or in 428 some cases may succeed and install broken OpenSSL libraries that 429 cause third-party software to link incorrectly and/or crash. 430 43120120507: 432 The database schema for makemandb was changed. You will 433 need to update the database using 'makemandb -f' or wait 434 for the next weekly run to fix it. 435 43620120319: 437 sys/conf/Makefile.kern.inc has been modified to adjust the 438 size of db_symtab automatically. You need to update dbsym in 439 your $TOOLDIR to build kernels with options SYMTAB_SPACE. If 440 you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your 441 mk.conf. 442 44320120216: 444 Default for MKCATPAGES changed to NO. Update builds will fail 445 unless DESTDIR is cleaned manually. If you built between 20120207 446 and 20120216, daily and weekly could have created an unreadable 447 /var/db/man.db index for apropos. Running makemandb -f or 448 the next run of weekly will fix it. 449 45020111227: 451 If you built between 20111225 and 20111227 you need to remove 452 /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the 453 bump has been reverted. 454 45520111125: 456 The "rnd" pseudodevice has been added to sys/conf/std, which 457 means it should no longer be explicitly listed in kernel 458 configuration files. The line "pseudo-device rnd" should be 459 removed from any custom kernel config files users may have. 460 46120111119: 462 A problem with the datastructures used by the rndctl(8) 463 utility (pointers in datastructures in an array, making 32->64 464 bit compatibility very painful) has been fixed in a 465 non-backwards-compatible way. If you replace your kernel, 466 replace your rndctl executable too. 467 46820111001: 469 the prop_*_send_syscall() functions from proplib(3) have been 470 changed and their new version is not backward compatible with the old 471 one. So ensure that all consumers of these functions (currently: 472 quota2 code and its tests) are updated together with the new lib. 473 47420110817: 475 sparc has been changed to use GCC 4.5.3, so any objdir or 476 DESTDIR for them should be deleted before updating. 477 47820110806: 479 i386 and amd64 have been changed to use GCC 4.5.3, so any 480 objdir or DESTDIR for them should be deleted before updating. 481 48220110805: 483 The update to GCC 4.5.3 requires a non-trivial portion of 484 the tree to be cleaned. Best to delete both objdir and 485 DESTDIR before running this update. So far, only the 486 sparc64, mips and powerpc platforms have changed. 487 48820110803: 489 The layout of external/public-domain/xz has changed. To do an 490 update build you will have to remove the contents of the OBJDIR 491 for external/public-domain/xz/bin by hand as the xz entry there 492 is now a directory. 493 49420110410: 495 The configuration of src/tools/gcc has changed. To do an 496 update build you have to clean both tools/binutils and 497 tools/gcc by hand. 498 49920110328: 500 Building the Xorg binary was moved into a subdirectory to fix 501 ordering issues with "make all". It may be necessary to remove 502 the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86 503 if your update build fails, as the "Xorg" entry there is now a 504 directory. 505 50620110121: 507 Assembler files no longer use -traditional-cpp. This can break 508 the build of individual parts of the tree. This is handled 509 correctly by build.sh. Manual builds have to update /usr/share/mk 510 and re-run config(1) for any kernel configurations as needed. 511 51220101217: 513 The tcpdump(8) program was changed to drop privileges and chroot(2) 514 by default. It may be necessary to manually update passwd(5) and 515 group(5) in order to make the program work with existing setups. 516 51720101125: 518 The latest changes to setenv(3) dissallow setting environment 519 variables with names that contain '='. Revision 1.18 of env.c 520 assumed that this was allowed. Installing a new libc with an 521 old copy of /usr/bin/env causes env x=1 printenv | grep x= to 522 break which affects the autoconf tests for dependency finding, 523 so building gcc will end up printing: 524 checking dependency style of gcc... none 525 configure: error: no usable dependency style found 526 Fix it by rebuilding and re-installing env. 527 52820101119: 529 Recent Xorg updates in xsrc/external/mit/ may cause various build 530 or run-time problems. Delete your entire DESTDIR and OBJDIR if you 531 have any build problems with xsrc, or problems with mismatched 532 versions between xorg-server and drivers. 533 53420100604: 535 The update of ATF to 0.9 causes old tests written in shell to fail 536 unless they are rebuilt. If you are building with MKUPDATE=yes, 537 you need to clean the src/external/bsd/atf/tests/ and the src/tests/ 538 trees by hand. 539 54020100522: 541 Recent Xorg updates in xsrc/external/mit/ will cause various build 542 problems. Delete your entire DESTDIR and OBJDIR if you have any 543 build problems with xsrc. 544 54520100522: 546 private section of <ctype.h> was split, and now mklocale(1) 547 include ctype_local.h, so you have to make cleandir in tools/mklocale. 548 54920100520: 550 The location of the xkb compiled descriptions has changed. Please 551 remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR. 552 55320100222: 554 The shared objects file extension has been changed from .so to 555 .pico, in order to avoid conflicts with shared libraries names 556 libXX.so. All now stale regular .so files can be removed from 557 your object directories. 558 55920100204: 560 The termcap database has been removed from the sources, 561 but has not been marked obsolete so it is not removed 562 from the system when upgrading. 563 As such, you will need to remove them from your object 564 and destination directories. 565 56620091101: 567 After updating, it may be necessary to make the 'cleandir' 568 target in src/tools/yacc/ and in src/usr.bin/yacc/ before a 569 'build.sh -u tools' or 'build.sh -u distribution'. Ditto 570 src/tools/lex/ and src/usr.bin/lex/. 571 57220091001: 573 On amd64 you must rebuild tools (to get the new binutils) 574 before building a kernel, or the build fails on cpufunc.S. 575 57620091001: 577 An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb 578 symlink, failing the build. Delete the link, and the subdir 579 it is in, and retry your build. 580 58120090718: 582 libc build changed so that strchr() provides the extra entry 583 point for index(). Update build of libc.a (and libc_pic.a) 584 may fail because the archive contains the unwanted index.o. 585 (Similarly for strrchr() and rindex().) 586 58720090709: 588 Native Xorg was upgraded again. Builds will probably fail again 589 without a clean objdir, at least for src/external/mit/xorg. 590 59120090616: 592 Native Xorg was upgraded. Builds will need a clean objdir for 593 src/external/mit/xorg. Upgrading a system from sets will not 594 work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc 595 subdirectory has been changed into a file, and this needs to 596 be manually "rm -r"'ed before installing xbase.tgz. 597 59820090501: 599 Several new functions were added to string.h/libc, and this 600 can cause autoconf problems during the tool build for people 601 who fail to clean out their tools objects properly. If you 602 note messages about stpcpy, stpncpy or strnlen accompanying a 603 failure during the tool build, clean out all your tools 604 objects and start again. 605 60620090325: 607 The i386 port was switched to i486 default toolchain. This requires 608 cleaning your src/tools directory and $TOOLDIR and rebuilding them. 609 61020090126: 611 The __posix_fadvise50 system call changed assembly stub type. You 612 need to 'rm -f __posix_fadvise50.*' in the libc build directory 613 to avoid using the old assembly stub. 614 61520090202: 616 pkg_install now depends on the pkgdb cache for automatic conflict 617 detection. It is recommended to rebuild the cache with 618 ``pkg_admin rebuild''. 619 62020090110: 621 time_t and dev_t have been bumped to 64 bit quantities. To upgrade: 622 1. Make sure your kernel has COMPAT_50 in it. Build and install. 623 This is needed even in the MODULAR kernel because there is 624 conditionally compiled code in rtsock.c. 625 2. make sure build.sh completes and the binaries in a chroot work 626 before installing. 627 3. If you don't use build.sh and you build directly to root, and 628 your build breaks in the middle, don't despair. Make sure headers 629 are installed properly, and start building libraries first libc 630 and libutil, install them and then continue building all the 631 libraries in src/lib and src/gnu/lib and install them. Once 632 the new libraries are installed, you can restart the build. 633 4. If you compile packages and you notice link time warnings, 634 rebuild the required packages to update their shared libraries. 635 Any package you rebuild will require rebuilding all the packages 636 that depend on it. 637 5. Next time you run pwd_mkdb with the new binary, the file 638 will be upgraded and it will not be backwards compatible. 639 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see 640 lastlogx(5)) have been versioned, and there is a heuristic 641 for utmp. You are better off removing the old files after 642 upgrading. The automated clearing of /var/run during 643 boot, and the automated rotating of files in /var/log by 644 newsyslog(8), may mean that you do not have to remove the 645 files manually. 646 7. The optional accounting file (/var/account/acct, see 647 accton(8)) has not been versioned, and will need to be 648 removed. The automatic rotation of the accounting file by 649 /etc/daily limits the bad consequences of failure to remove 650 the file. 651 8. Application software that writes time_t to binary files on 652 disk will break or need attention. Most notably: if you are 653 using PostgreSQL < 8.4, you need to dump your databases, 654 rebuild PostgreSQL with the new time_t, then restore. 655 65620081219: 657 config(1) has been updated, and one of the files it creates - 658 swapnetbsd.o - has changed format. You need to rebuild config 659 (done automatically by build.sh) and then you need to rerun 660 config on all kernel configuration files before rebuilding those 661 kernels. 662 66320081205: 664 If you build with MKX11=no, you should remove /etc/rc.d/xdm and 665 /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc 666 set and will appear as extra files for MKX11=no update builds. 667 66820081122: 669 On i386, various kernel options(4) in GENERIC including 670 file systems have been disabled and moved into kernel modules. 671 Before trying a new GENERIC kernel, you have to prepare the 672 following files as well as a new GENERIC kernel: 673 674 - build and install kernel modules from src/sys/modules 675 676 - install the latest bootloader, which will load a module 677 for the file system from which the kernel is loaded automatically 678 679 If you have to load your kernel from a file system which is not of 680 the same type as the root file system, you have to load the necessary 681 file system module manually on the boot prompt or in the boot.cfg file. 682 68320080827: 684 If you built and installed a libc from sources between 685 2008/08/20 and 2008/08/26 you got a broken strtouq(3) 686 which results in false errors reported by lint(1). 687 Since this breaks the libc build itself, manual help is 688 needed -- lint must be disabled temporarily, e.g.: 689 $ (cd lib/libc && make MKLINT=no dependall install) 690 69120080813: 692 MKDEBUG build was broken because the .depend files did not know 693 about .go files. You need to remove all .depend files and rebuild. 694 69520080802: 696 A regression in binary compatibility for pthread_mutex_t has 697 been fixed. Unfortunately, the price is breaking compatibility 698 for -current. 699 700 Threaded programs (using libpthread) and C++ programs (using 701 libstdc++) compiled after 20070907 and before 20080802 need to 702 be recompiled. 703 704 One way to find affected pkgsrc packages: 705 706 $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO 707 $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO 708 70920080731: 710 WAPBL (metadata journaling support) has been added, but at this 711 time isn't backwards compatible with pre-WAPBL aware kernels 712 and userland (fsck_ffs in particular). Please make sure you 713 don't use a journaled filesystem with an older kernel/userland, 714 especially an uncleanly mounted journaled filesystem. WAPBL 715 also requires the super block to be in the UFS2 format. You 716 can use fsck_ffs -c 4 to update the superblock format. 717 71820080721: 719 Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR 720 isn't defined. 721 72220080531: 723 The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed 724 from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8) 725 utility needs to be rebuilt and reinstalled as older binaries 726 won't work correctly. The following sequence of commands: 727 728 $ (cd sys/sys/ && nbmake-$arch includes) 729 $ (cd sbin/drvctl/ && nbmake-$arch clean) 730 $ (cd sbin/drvctl/ && nbmake-$arch all) 731 732 leaves new drvctl utility in sbin/drvctl build directory. 733 73420080503: 735 The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE. 736 73720080521: 738 For a while, unprivileged UPDATE builds would fail to 739 succeed at the checkflist stage, complaining that 740 ${DESTDIR}/stand/<arch>/ did not exist. A fix for this 741 problem was committed to share/mk/bsd.kmodule.mk, revision 1.9. 742 If you already hit this problem, update the .mk file, 743 remove ${DESTDIR}/stand/<arch>, and re-run the build. 744 74520080303: 746 Linker warnings are now fatal if $WARNS>0. 747 74820080126: 749 The posix_fadvise system call has been changed from an assembly 750 stub, to a c file that calls an assembly stub. You need to 751 'rm -f posix_fadvise.* .depend' in the libc build directory to 752 avoid using the old assembly stub. 753 75420071209: 755 The acpiec(4) driver has been split into two attachments. If you 756 get ACPI errors before the attachment, please update your kernel 757 configuration file appropriately or see GENERIC for more details. 758 75920071115: 760 The it(4) driver has been renamed to itesio(4) and the old port 761 argument specified in the kernel configuration file is not valid 762 anymore. The itesio(4) driver now uses the Super I/O address port 763 rather than the EC address port. Please update your kernel 764 configuration file appropriately or see GENERIC for more details. 765 76620071028: 767 The pccons(4) driver has been removed from the NetBSD/shark port. 768 You need to update any custom kernel configuration file you have 769 to remove any references to pccons (which includes removing the 770 now useless XSERVER option) and replace them with the correct 771 entries for the wscons driver. See the GENERIC configuration file 772 for more details. 773 77420070913: 775 A latent bug in dhclient/dhcpd that caused it to be unable to 776 enumerate interfaces was fixed. The bug began to cause 777 problems after 20070911 when the kernel's SIOCGIFCONF 778 implementation was repaired. From 20070529 to 20070911 racoon 779 could not enumerate interfaces. (These are noted because 780 normal kernel/userspace version matching hygiene is not 781 sufficient to avoid this problem.) Ensure that both kernel 782 and userland are from after 20070913. 783 78420070703: 785 nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It 786 calls the target-specific strip program, and the logic to pass 787 down STRIP from make has been removed. This requires a 788 re-installation of tools. 789 79020070422: 791 The way OS emulations lookup filenames inside the emulation root 792 has been changed. Rather than modify the pathname (and copy back 793 to userspace) namei() and lookup() directly check the emulation 794 root. One side effect is that absolute symlinks inside the emulated 795 root file system will be relative to that file system - unless they 796 start /../ this is useful when the emulated root is a real install 797 that has such links. 798 This might affect symlinks that have been added to reference outside 799 the emulated root. 800 80120070412: 802 The pckbc driver on sgimips IP32 has been removed. Use macekbc 803 instead. See the GENERIC32_IP3x kernel configuration for an 804 example. 805 80620070319: 807 src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so 808 on many platforms due to incorrect flags settings. If you 809 updated and built after about 20070315, do "nbmake-$arch 810 cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a 811 rebuild of object files that might have been built 812 incorrectly, and ensure that you have at least 813 src/lib/libc/Makefile 1.130. 814 81520070210: 816 src/sys/sys/{sa.h,savar.h} were removed. 817 find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \ 818 | xargs egrep -l '/sa.h|/savar.h' | xargs rm 819 will allow dependencies on those files to get get rebuilt 820 82120070209: 822 The threading model was changed when the newlock2 branch 823 was merged to NetBSD-current. If you boot with a new 824 kernel (version 4.99.10), then you also need a new pthread 825 library (/usr/lib/libpthread.so.0.7). If you boot with 826 an old kernel, then you need the old pthread library 827 (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and 828 the pthread library in sync, old threaded applications should 829 continue to work with an old or new kernel. Note that named(8) 830 is the only threaded application in the base system. 831 83220061214: 833 Following the move of string_to_flags() and flags_to_string() 834 from the bin/ls/ sources to libutil, users doing UPDATE builds 835 will need to do a "make cleandir" in 836 tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/, 837 bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/, 838 usr.bin/xinstall/, libexec/ftpd/, rescue/, as well 839 as the installation images in distrib/ 840 in order to excise stale references to the old stat_flags.h header 841 file in the ls sources -- stat_flags.h has been removed. 842 84320061108: 844 The configure script used in the src/tools/gcc compiler has been 845 changed to indicate that our libc has ssp support built-in and 846 does not depend on -lssp and -lssp-nonshared. You'll need to 847 make clean in src/tools/gcc first to rebuild the compiler. 848 84920061009: 850 The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer 851 available. Use net.inet{,6}.tcp{,6}.congctl.selected instead. 852 85320060814: 854 The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been 855 withdrawn. Use vidcvideo and pckbd instead. See the GENERIC 856 kernel configuration for an example. X servers from the last 857 few years should cope. 858 85920060703: 860 MPACPI is no more. We always configure PCI interrupts using ACPI 861 if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed 862 to ACPI_SCANPCI. Thanks to work from fvdl. 863 86420060627: 865 socket(2) has changed, and its system call has been versioned. 866 For userlands with the old version of socket(2), make sure that 867 your kernel has 'options COMPAT_30' set, or else 'bad system call' 868 errors will result. 869 870Hints for a more successful build: 871^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 872 Use build.sh, but do not use its "expert mode": 873 This will automatically build the tools in the 874 correct order, and it will keep the tools and the 875 new build products from interfering with the running 876 system. This will allow you to ignore most of the 877 other advice in this file. 878 Build a new kernel first: 879 This makes sure that any new system calls or features 880 expected by the new userland will be present. This 881 helps to avoid critical errors when upgrading. 882 Use object directories: 883 This helps to keep stale object 884 files from polluting the build if a Makefile "forgets" 885 about one. It also makes it easier to clean up after 886 a build. It's also necessary if you want to use the 887 same source tree for multiple machines. 888 To use object directories with build.sh: 889 a) invoke build.sh with the "-M" or "-O" options. 890 To use object directories without using build.sh: 891 a) cd /usr/src ; make cleandir 892 b) Add "OBJMACHINE=yes" to /etc/mk.conf 893 c) Add "MKOBJDIRS=yes" to /etc/mk.conf 894 d) cd /usr/src ; make build 895 Note that running "make obj" in a directory will create 896 in obj.$MACHINE directory. 897 Build to a DESTDIR: 898 This helps to keep old installed files (especially libraries) 899 from interfering with the new build. 900 To build to a DESTDIR with build.sh, use the "-D" option. 901 To build to a DESTDIR without using build.sh, set the DESTDIR 902 environment variable before running make build. It should be 903 set to the pathname of an initially empty directory. 904 Problems: if you do not use build.sh, you might need to 905 update critical utilities without using DESTDIR since 906 nothing is executed from what is installed in DESTDIR. 907 (See critical utils, below.) 908 Build often: 909 This keeps critical utilities current enough to not choke 910 on any other part of the source tree that depends on up to 911 date functionality. If you use build.sh, you should not have 912 this problem. 913 914What to do if things don't work: 915^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 916When things don't work there are usually a few things that commonly 917should be done. 918 1) make includes 919 This should be done automatically by make build. 920 2) cd share/mk && make install 921 Again, automatically done by make build. 922 923Failsafe rebuild of a small part of the tree: 924^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 925To make sure you rebuild something correctly you want to do 926something like the following: 927 1) Make sure the includes and .mk files are up to date. 928 2) Make sure any program used to build the particular 929 utility is up to date. (yacc, lex, etc...) 930 3) cd ...path/to/util... 931 make cleandir 932 rm ...all obj directories... 933 make cleandir # yes, again 934 make obj 935 make depend && make 936 937Failsafe rebuild of the entire tree: 938^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 939If you really want to make sure the source tree is clean and 940ready for a build try the following. Note that sourcing /etc/mk.conf 941(a make(1) Makefile) in this manner is not right, and will not work 942for anyone who uses any make(1) features in /etc/mk.conf. 943 944---cut here--- 945#!/bin/sh 946. /etc/mk.conf 947 948if [ -z $NETBSDSRCDIR ] ; then 949 NETBSDSRCDIR=/usr/src 950fi 951if [ \! -d $NETBSDSRCDIR ] ; then 952 echo Unable to find sources 953 exit 1 954fi 955find $NETBSDSRCDIR -name \*.o -o -name obj.\* -o -name obj -exec rm \{\} \; 956 957if [ -z $BSDOBJDIR ] ; then 958 BSDOBJDIR=/usr/obj 959fi 960if [ -d $BSDOBJDIR ] ; then 961 rm -rf $BSDOBJDIR 962fi 963 964cd $NETBSDSRCDIR && make cleandir 965 966---cut here--- 967 968Critical utilities: 969^^^^^^^^^^^^^^^^^^^ 970 usr.bin/compile_et 971 usr.bin/make 972 usr.bin/yacc 973 usr.bin/lex 974 usr.bin/xlint 975 usr.bin/config 976 977Other problems and possible solutions: 978^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 979Symptom:Complaints involving a Makefile. 980Fix: Rebuild usr.bin/make: 981 cd usr.bin/make && make && make install 982 Or, a failsafe method if that doesn't work: 983 cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin 984 985Fix: Make sure .mk files are up to date. 986 cd share/mk && make install 987 988Symptom:Kernel `config' fails to configure any kernel, including GENERIC. 989Fix: Rebuild usr.bin/config 990 991Symptom: 992Fix: Rebuild usr.bin/yacc 993 994Symptom: 995Fix: Rebuild usr.bin/lex 996 997Symptom: 998Fix: rm /usr/lib/libbfd.a 999 1000Symptom:Obsolete intermediate files are used during compilation 1001Fix: Try the following sequence of commands in the directory in question. 1002 make cleandir; rm `make print-objdir`; make cleandir; make obj 1003 (If you built the tree without "make obj" in the past, obsolete files 1004 may remain.
