1$NetBSD: UPDATING,v 1.379 2025/04/27 23:30:39 kre 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 2220250427: 23 The KERNEL_DIR option to build.sh is now functional. Set it 24 with ``-V KERNEL_DIR=yes'' on your build.sh command. 25 With this, you can now colocate kernel and associated modules 26 in /netbsd/{kernel,kernel.dbg,modules} instead of having the 27 kernel in / but modules in /stand. 28 29 Note that you'll need new bootstrap code to use this feature. 30 31 This completes work begun many years ago by christos@ :-) 32 3320250413: 34 A change to bsd.lib.mk requires a clean build of all libraries. 35 3620250131: 37 The switch to the new jemalloc requires cleaning in libc. 38 3920241122: 40 Changes to various libraries' build options require cleaning 41 their objdirs in update builds: 42 43 cd external/bsd/file/lib && $TOOLDIR/bin/nbmake-$ARCH clean 44 cd external/bsd/libarchive/lib && $TOOLDIR/bin/nbmake-$ARCH clean 45 cd external/public-domain/xz/lib && $TOOLDIR/bin/nbmake-$ARCH clean 46 47 Also, for architectures with MKCOMPAT, it is necessary to clean 48 the compat objdirs too. The easiest way is: 49 50 rm -rf OBJDIR/compat/*/*/external/bsd/file/lib 51 rm -rf OBJDIR/compat/*/*/external/bsd/libarchive/lib 52 rm -rf OBJDIR/compat/*/*/external/public-domain/xz/lib 53 54 Changes to bsd.lib.mk to improve detecting differences in 55 shared library symbol exports may cause some .actsym files in 56 the objdir to become stale in update builds. 57 58 To work around this, delete all files matching `*.actsym' in 59 the objdir. For example: 60 61 find OBJDIR -name '*.actsym' -type f -print0 | xargs -0 rm 62 6320241104: 64 Changes around the integration of the zstd compression 65 library may require manual deletion of some object directories 66 if you update from a build from a few days ago: 67 rm -rf DESTDIR/usr/lib/*/libarchive* 68 rm -rf DESTDIR/usr/lib/*/libmagic* 69 rm -rf DESTDIR/usr/lib/*/libzstd* 70 rm -rf DESTDIR/usr/lib/libarchive* 71 rm -rf DESTDIR/usr/lib/libmagic* 72 rm -rf DESTDIR/usr/lib/libzstd* 73 rm -rf OBJDIR/compat/*/*/external/bsd/file/ 74 rm -rf OBJDIR/compat/*/*/external/bsd/libarchive/ 75 rm -rf OBJDIR/compat/*/*/external/bsd/zstd/ 76 rm -rf OBJDIR/external/bsd/file/ 77 rm -rf OBJDIR/external/bsd/libarchive/ 78 rm -rf OBJDIR/external/bsd/zstd/ 79 rm -rf OBJDIR/external/gpl3/gcc/ 80 rm -rf OBJDIR/tools/gcc/ 81 8220240926: 83 Building -current when running on amd64 from about 20240924 84 to about 20240926 will not work due to a "malloc_np.h" 85 error. Please downgrade to a version from 20240924 or older, 86 or upgrade to a newer version e.g. using a binary release from 87 the NetBSD build servers. 88 8920240923: 90 Update builds will require cleaning the object directories for 91 jemalloc (like: "rm -rf $OBJ/external/bsd/jemalloc*") and the 92 libc dependency files (like: "rm $OBJ/lib/libc/jemalloc.*"). 93 On architectures with COMPAT libs, those also have to be cleaned, 94 e.g. on sparc64: "rm -rf $OBJ/compat/sparc64/sparc/external/bsd/jemalloc*" 95 and "rm $OBJ/compat/sparc64/sparc/lib/libc/jemalloc.*". 96 9720240817: 98 Update builds will require cleaning in src/external/historical/nawk/bin 99 in order to remove the awk binary since now there is a subdirectory 100 called awk. 101 10220240812: 103 Update builds will require removing the tools objdir for gdb 104 if building with MKCROSSGDB=yes. All architectures use gdb.old 105 now. 106 10720240630: 108 Update builds will require removing the tools objdir for binutils 109 (as most architectures should use binutils.old now). 110 11120240610: 112 Update builds are likely to require removing the objdir for 113 distrib/<arch>/cdroms - or at least references to libarchive 114 from within there after the recent libarchive update. 115 11620240504: 117 Update builds on x86 require making the `cleandir' target in 118 lib/libm, or deleting the objdir for lib/libm. 119 12020240423: 121 Update builds with x11 may fail after switching to Mesa 21. 122 12320240410: 124 Update builds may require manually deleting 125 $DESTDIR/var/run/named (and, potentially, 126 $DESTDIR/var/run/lwresd) in order to avoid checkflist failure. 127 12820240409: 129 32-bit compatibility libraries were moved into the base32 130 and debug32 sets. HTML man pages were moved into the manhtml set. 131 13220230828: 133 If: 134 - you updated to current and ran postinstall between 20230826 135 and 20230828 inclusive, and 136 - you are not using anything outside the base system to 137 populate /etc/openssl/certs (e.g., manually adding 138 certificates or using ca-certificates or mozilla-rootcerts or 139 mozilla-rootcerts-openssl from pkgsrc), 140 delete /etc/openssl/certs and rerun postinstall or just 141 `certctl rehash'. 142 143 Otherwise, certctl(8) will think someone else has left 144 /etc/openssl/certs in the way and will avoid clobbering it on 145 upgrade from older NetBSD. 146 14720230718: 148 build.sh will use mk.conf in the same directory as build.sh instead 149 of /etc/mk.conf, unless MAKECONF is already defined in the environment. 150 15120230714: 152 Import of gcc 10.5 requires a clean build of at least tools/gcc 153 and external/gpl3/gcc* object directories. An update build 154 without cleaning will result in obscure failures in rare corner 155 cases. 156 15720230604: 158 Building native kernels with the installed make(1) instead of 159 the $TOOLDIR/bin/nbmake-${arch} wrapper will fail if userland 160 has not been updated. Note that this is an unsupported build 161 configuration (but usually works if userland is -current enough). 162 16320230523: 164 ctfmerge was fixed as macOS host tool. This may require a clean tools 165 rebuild to detect the update to tools/compat/configure. 166 16720230515: 168 New openssl build requires removal of the crypto/external/bsd/openssl 169 and tests/crypto/libcrypto subdirectories in the ${OBJDIR} hierarchy. 170 Otherwise test results may be wrong due to wrong "golden" output 171 files being installed. 172 17320230322: 174 Fixes for moved /lib/libisns* mean that builds will complain about 175 ./usr/lib/libisns* being missing until src/lib/libisns is forced 176 to (re)install the files, including the symlinks. The simplest 177 way is to clean this subdir before building. 178 17920230112: 180 New binutils require an updated ld.elf_so. If you are doing 181 (unsupported) in-place self builds (with the -E flag to build.sh), 182 make sure to have installed latest ld.elf_so before you rebuild 183 userland. 184 18520221116: 186 The addition to NetBSD's version of UFS2 of support for extended 187 attributes broke backward compatibility with previous releases 188 of NetBSD, so UFS2 has been restored to being compatible with 189 previous NetBSD releases by disabling extended attributes. 190 (Note that ACLs are implemented as extended attributes, so 191 this changes disables ACLs as well.) 192 193 Support for UFS2 with extended attributes is now available in a new 194 UFS variant called UFS2ea. If you have created extended attributes 195 in an original UFS2 file system then "fsck -p" will now fail due to 196 the unexpected presence of extended attributes and "fsck -y" will 197 remove all extended attributes. If you wish to preserve extended 198 attributes rather than delete them, there is a utility to convert 199 a UFS2 file system to UFS2ea and leave extended attributes in place, 200 but this should be used with caution since it will preserve any 201 extended attributes that have been corrupted by the backward 202 incompatibility too. 203 204 If you wish to use a UFS2ea file system as your root file system, 205 then you will need to update your boot loader to a version that 206 supports UFS2ea. 207 208 For more information, see: 209 https://wiki.netbsd.org/features/UFS2ea 210 21120221111: 212 The new libdrm import worsened the conflict issues for the 213 kdump/ktruss ioctl, and i915 now conflicts with base, and has 214 been turned off. This will cause update build issues like: 215 216 kdump-ioctl.c:12175:143: error: 'DRM_IOCTL_I915_DESTROY_HEAP' 217 undeclared here (not in a function); 218 did you mean 'DRM_IOCTL_MODE_DESTROY_DUMB'? 219 220 You'll need to clean usr.bin/ktruss, usr.bin/kdump, and rescue. 221 22220220921: 223 Since the kernel version was bumped to 9.99.100, the bootloader 224 must be updated on x86 or EFI boot platforms in order to load 225 modules from boot.cfg(5) or interactively at the bootloader 226 prompt. 227 228 The kernel can still load modules at runtime, with modload(8) 229 or modules.conf(5), with no bootloader update. This will not 230 affect release branches because it only applies to patch 231 numbers >=100. 232 233 On x86 (i386 or amd64) with BIOS boot, this requires copying a 234 new /usr/mdec/boot to /boot. You can build this in the destdir 235 by running `$TOOLDIR/bin/nbmake-$ARCH dependall install' in 236 sys/arch/i386/stand. 237 238 On platforms with EFI boot (including x86 with EFI boot), this 239 requires copying a new /usr/mdec/boot*.efi to the EFI/BOOT/ 240 directory on the EFI system partition. The boot*.efi file is: 241 242 aarch64 bootaa64.efi 243 amd64 bootx64.efi 244 arm bootarm.efi (32-bit arm) 245 i386 bootx32.efi 246 247 You can build this in the destdir by running 248 `$TOOLDIR/bin/nbmake-$ARCH dependall install' in 249 sys/stand/efiboot/boot*. 250 25120220821: 252 Support for building extsrc/ has been deprecated. 253 EXTSRCSRCDIR and MKEXTSRC have been deprecated. 254 25520220714: 256 Updates to xorg-server and associated drivers may cause builds to 257 fail. Cleaning both DESTDIR and the xorg build tree may be needed. 258 25920220628: 260 Changes in the build of src/games/robots require a clean build 261 of that program. 262 26320211116: 264 Changes in the xorg build require clean obj dirs for external/mit/xorg 265 (or a full clean/non-update build). 266 26720211112: 268 Device tree sources were updated for evbarm. Some device nodes 269 (in particular, ld(4) devices on the ROCKPro64) will be renumbered. 270 27120211014: 272 MKPIE default for aarch64 has changed, a clean build is required. 273 27420210917: 275 Changed MNT_ACLS to default to POSIX1e ACLs instead of NFSv4 276 ACLs, to be compatible with FreeBSD. If you are using NFSv4 ACLs 277 and have "acls" in /etc/fstab you'll need to change it to "nfs4acls". 278 27920210711: 280 Updated GMP sources may require cleaning in tools/gmp and/or in 281 external/lgpl3/gmp/lib, particularly if GCC itself does not build. 282 28320210417: 284 GCC 10 was enabled for several platforms. If builds fail in either 285 tools/gcc or external/gpl3/gcc, first try cleaning those objects and 286 removing the $DESTDIR/usr/include/g++ subdirectory. 287 28820201016: 289 MIPS kernel modules have been disabled until they work. This will 290 turn up in extra files in the DESTDIR, which should be cleaned. 291 29220200925: 293 GNU MPC and MPFR have been updated. At least MPFR needs cleaning 294 in both the tools and external dirs. 295 29620200912: 297 GCC 9 has arrived for Arm and x86 platforms, and will be coming 298 for several more, as will binutils 2.34. Clean as required. 299 30020200907: 301 GCC 9 is coming, and binutils has been updated for MIPS. This 302 probably requires cleaning the tools/binutils. 303 30420200811: 305 GCC updates may require cleaning the objdir. This may occur 306 due to GCC 7.5 update, GCC 8.4 move to gcc.old, or the upcoming 307 GCC 9 upgrade. 308 30920200614: 310 blacklist* has been renamed to blocklist*. postinstall(8) 311 should handle the migration. 312 31320200601: 314 Due to a mistake in LIBISPRIVATE handling, .so libraries were 315 created in the build directories and need cleaning. 316 31720200311: 318 GCC 8 ports will need cleaning in src/tools/gcc and 319 src/external/gpl3/gcc due to GCC 8.4 update. 320 32120191118: 322 More architectures were switched to gcc8: 323 i386, ia64 powerpc64, sparc, sparc64, arm 324 The same comments as in 20191022 apply. 325 32620191112: 327 The LLVM update requires a clean rebuild for all architectures using 328 LLVM during the tools build phase (i386, amd64, aarch64). 329 33020191022: 331 Ports amd64 and aarch64 switched to GCC 8.3 by default. 332 In-place ("expert mode", build.sh -E) builds are not supported 333 when going from a GCC 7 userland to GCC 8. Do a regular 334 build to a different DESTDIR (or preferably: build.sh -U) at least 335 once and install sets, or download comp.{tar.xz,tgz} from the 336 daily builds and install that before doing the next in-place build. 337 33820191001: 339 GCC 8.3 was imported. Builds of src/tools/gcc may fail if 340 old builds with GCC 7 output now uses GCC 8. Clean this 341 directory, and also clean src/external/gpl3/gcc. 342 34320190903: 344 Files with names that coincide with existing files' names on 345 case-insensitive file systems were inadvertently committed, for 346 radeon GPU firmware. We cannot mark these as obsolete for 347 postinstall to fix, so if you updated src since 2019-08-26, and 348 ran build.sh distribution or ran build.sh release, you must 349 manually delete the following files in your DESTDIR (which is 350 usually $OBJDIR/destir.$ARCH), or from / if you have installed 351 them: 352 353 /libdata/firmware/radeon/bonaire_ce.bin 354 /libdata/firmware/radeon/bonaire_mc.bin 355 /libdata/firmware/radeon/bonaire_me.bin 356 /libdata/firmware/radeon/bonaire_mec.bin 357 /libdata/firmware/radeon/bonaire_pfp.bin 358 /libdata/firmware/radeon/bonaire_rlc.bin 359 /libdata/firmware/radeon/bonaire_sdma.bin 360 /libdata/firmware/radeon/bonaire_smc.bin 361 /libdata/firmware/radeon/bonaire_uvd.bin 362 /libdata/firmware/radeon/hainan_ce.bin 363 /libdata/firmware/radeon/hainan_mc.bin 364 /libdata/firmware/radeon/hainan_me.bin 365 /libdata/firmware/radeon/hainan_pfp.bin 366 /libdata/firmware/radeon/hainan_rlc.bin 367 /libdata/firmware/radeon/hainan_smc.bin 368 /libdata/firmware/radeon/hawaii_ce.bin 369 /libdata/firmware/radeon/hawaii_mc.bin 370 /libdata/firmware/radeon/hawaii_me.bin 371 /libdata/firmware/radeon/hawaii_mec.bin 372 /libdata/firmware/radeon/hawaii_pfp.bin 373 /libdata/firmware/radeon/hawaii_rlc.bin 374 /libdata/firmware/radeon/hawaii_sdma.bin 375 /libdata/firmware/radeon/hawaii_smc.bin 376 /libdata/firmware/radeon/kabini_ce.bin 377 /libdata/firmware/radeon/kabini_me.bin 378 /libdata/firmware/radeon/kabini_mec.bin 379 /libdata/firmware/radeon/kabini_pfp.bin 380 /libdata/firmware/radeon/kabini_rlc.bin 381 /libdata/firmware/radeon/kabini_sdma.bin 382 /libdata/firmware/radeon/kaveri_ce.bin 383 /libdata/firmware/radeon/kaveri_me.bin 384 /libdata/firmware/radeon/kaveri_mec.bin 385 /libdata/firmware/radeon/kaveri_mec2.bin 386 /libdata/firmware/radeon/kaveri_pfp.bin 387 /libdata/firmware/radeon/kaveri_rlc.bin 388 /libdata/firmware/radeon/kaveri_sdma.bin 389 /libdata/firmware/radeon/mullins_ce.bin 390 /libdata/firmware/radeon/mullins_me.bin 391 /libdata/firmware/radeon/mullins_mec.bin 392 /libdata/firmware/radeon/mullins_pfp.bin 393 /libdata/firmware/radeon/mullins_rlc.bin 394 /libdata/firmware/radeon/mullins_sdma.bin 395 /libdata/firmware/radeon/oland_ce.bin 396 /libdata/firmware/radeon/oland_mc.bin 397 /libdata/firmware/radeon/oland_me.bin 398 /libdata/firmware/radeon/oland_pfp.bin 399 /libdata/firmware/radeon/oland_rlc.bin 400 /libdata/firmware/radeon/oland_smc.bin 401 /libdata/firmware/radeon/pitcairn_ce.bin 402 /libdata/firmware/radeon/pitcairn_mc.bin 403 /libdata/firmware/radeon/pitcairn_me.bin 404 /libdata/firmware/radeon/pitcairn_pfp.bin 405 /libdata/firmware/radeon/pitcairn_rlc.bin 406 /libdata/firmware/radeon/pitcairn_smc.bin 407 /libdata/firmware/radeon/tahiti_ce.bin 408 /libdata/firmware/radeon/tahiti_mc.bin 409 /libdata/firmware/radeon/tahiti_me.bin 410 /libdata/firmware/radeon/tahiti_pfp.bin 411 /libdata/firmware/radeon/tahiti_rlc.bin 412 /libdata/firmware/radeon/tahiti_smc.bin 413 /libdata/firmware/radeon/verde_ce.bin 414 /libdata/firmware/radeon/verde_mc.bin 415 /libdata/firmware/radeon/verde_me.bin 416 /libdata/firmware/radeon/verde_pfp.bin 417 /libdata/firmware/radeon/verde_rlc.bin 418 /libdata/firmware/radeon/verde_smc.bin 419 420 We will re-import these radeon firmware images another way 421 later. 422 42320190727: 424 The uefi bootloader has gained tftp support and needs a clean 425 build. If you do update builds, manually clean its object 426 directory by something like: 427 cd sys/arch/i386/stand/efiboot && make clean 428 42920190723: 430 The jemalloc allocator in libc is now built without extended 431 debugging (for performance reasons). In update builds make sure 432 to rebuild it completely, by removing all affected object files, 433 including compat builds, something like: 434 cd /usr/obj && find . -type d -name jemalloc|xargs rm -rf 435 43620190207: 437 GCC 7 switched for many ports. Update builds are likely to fail. 438 439Hints for a more successful build: 440^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 441 Use build.sh, but do not use its "expert mode": 442 This will automatically build the tools in the 443 correct order, and it will keep the tools and the 444 new build products from interfering with the running 445 system. This will allow you to ignore most of the 446 other advice in this file. 447 Build a new kernel first: 448 This makes sure that any new system calls or features 449 expected by the new userland will be present. This 450 helps to avoid critical errors when upgrading. 451 Use object directories: 452 This helps to keep stale object 453 files from polluting the build if a Makefile "forgets" 454 about one. It also makes it easier to clean up after 455 a build. It's also necessary if you want to use the 456 same source tree for multiple machines. 457 To use object directories with build.sh: 458 a) invoke build.sh with the "-M" or "-O" options. 459 To use object directories without using build.sh: 460 a) cd /usr/src ; make cleandir 461 b) Add "OBJMACHINE=yes" to /etc/mk.conf 462 c) Add "MKOBJDIRS=yes" to /etc/mk.conf 463 d) cd /usr/src ; make build 464 Note that running "make obj" in a directory will create 465 in obj.$MACHINE directory. 466 Build to a DESTDIR: 467 This helps to keep old installed files (especially libraries) 468 from interfering with the new build. 469 To build to a DESTDIR with build.sh, use the "-D" option. 470 To build to a DESTDIR without using build.sh, set the DESTDIR 471 environment variable before running make build. It should be 472 set to the pathname of an initially empty directory. 473 Problems: if you do not use build.sh, you might need to 474 update critical utilities without using DESTDIR since 475 nothing is executed from what is installed in DESTDIR. 476 (See critical utils, below.) 477 Build often: 478 This keeps critical utilities current enough to not choke 479 on any other part of the source tree that depends on up to 480 date functionality. If you use build.sh, you should not have 481 this problem. 482 483What to do if things don't work: 484^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 485When things don't work there are usually a few things that commonly 486should be done. 487 1) make includes 488 This should be done automatically by make build. 489 2) cd share/mk && make install 490 Again, automatically done by make build. 491 492Failsafe rebuild of a small part of the tree: 493^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 494To make sure you rebuild something correctly you want to do 495something like the following: 496 1) Make sure the includes and .mk files are up to date. 497 2) Make sure any program used to build the particular 498 utility is up to date.

Note that sourcing /etc/mk.conf 510(a make(1) Makefile) in this manner is not right, and will not work 511for anyone who uses any make(1) features in /etc/mk.conf. 512 513---cut here--- 514#!/bin/sh 515. /etc/mk.conf 516 517if [ -z $NETBSDSRCDIR ] ; then 518 NETBSDSRCDIR=/usr/src 519fi 520if [ \! -d $NETBSDSRCDIR ] ; then 521 echo Unable to find sources 522 exit 1 523fi 524find $NETBSDSRCDIR -name \*.o -o -name obj.\* -o -name obj -exec rm \{\} \; 525 526if [ -z $BSDOBJDIR ] ; then 527 BSDOBJDIR=/usr/obj 528fi 529if [ -d $BSDOBJDIR ] ; then 530 rm -rf $BSDOBJDIR 531fi 532 533cd $NETBSDSRCDIR && make cleandir 534 535---cut here--- 536 537Critical utilities: 538^^^^^^^^^^^^^^^^^^^ 539 usr.bin/make 540 usr.bin/yacc 541 usr.bin/lex 542 usr.bin/xlint 543 usr.bin/config 544 545Other problems and possible solutions: 546^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 547Symptom:Complaints involving a Makefile. 548Fix: Rebuild usr.bin/make: 549 cd usr.bin/make && make && make install 550 Or, a failsafe method if that doesn't work: 551 cd usr.bin/make && cc -DMAKE_NATIVE *.c -I. -o make \ 552 && install make /usr/bin 553 554Fix: Make sure .mk files are up to date. 555 cd share/mk && make install 556 557Symptom:Kernel `config' fails to configure any kernel, including GENERIC. 558Fix: Rebuild usr.bin/config 559 560Symptom:Obsolete intermediate files are used during compilation 561Fix: Try the following sequence of commands in the directory in question. 562 make cleandir; rm `make print-objdir`; make cleandir; make obj 563 (If you built the tree without "make obj" in the past, obsolete files 564 may remain.

If your cvs working tree 591 contains references to a directory that has been deleted on the 592 server in this way, then "cvs update" reports this error. 593Fix: Recursively delete the affected directory from your working tree 594 and try the update again. 595
