1 1.361 martin $NetBSD: UPDATING,v 1.361 2024/10/16 09:26:39 martin Exp $ 2 1.1 abs 3 1.123 jmc This file (UPDATING) is intended to be a brief reference to recent 4 1.123 jmc changes that might cause problems in the build process, and a guide for 5 1.123 jmc what to do if something doesn't work. 6 1.1 abs 7 1.123 jmc For a more detailed description of the recommended way to build NetBSD 8 1.123 jmc using build.sh, see the BUILDING file. 9 1.123 jmc 10 1.123 jmc Note that much of the advice in this UPDATING file was written before 11 1.123 jmc build.sh existed. Nevertheless, the advice here may be useful for 12 1.123 jmc working around specific problems with build.sh. 13 1.123 jmc 14 1.257 apb Sections are marked with "^^^^^". After the section on "Recent changes" 15 1.257 apb are several sections containing more general information. 16 1.257 apb 17 1.123 jmc See also: BUILDING, build.sh, Makefile. 18 1.1 abs 19 1.1 abs Recent changes: 20 1.1 abs ^^^^^^^^^^^^^^^ 21 1.230 tls 22 1.361 martin 20241015: 23 1.361 martin OpenSSL symbol changes require a full rebuild of all libs 24 1.361 martin and all binaries linked against libcrypto. Recommended 25 1.361 martin workaround is a clean build or removing the $OBJ directory 26 1.361 martin completely. 27 1.361 martin 28 1.360 wiz 20240926: 29 1.360 wiz Building -current when running on amd64 from about 20240924 30 1.360 wiz to about 20240926 will not work due to a "malloc_np.h" 31 1.360 wiz error. Please downgrade to a version from 20240924 or older, 32 1.360 wiz or upgrade to a newer version e.g. using a binary release from 33 1.360 wiz the NetBSD build servers. 34 1.360 wiz 35 1.358 martin 20240923: 36 1.358 martin Update builds will require cleaning the object directories for 37 1.359 martin jemalloc (like: "rm -rf $OBJ/external/bsd/jemalloc*") and the 38 1.359 martin libc dependency files (like: "rm $OBJ/lib/libc/jemalloc.*"). 39 1.359 martin On architectures with COMPAT libs, those also have to be cleaned, 40 1.359 martin e.g. on sparc64: "rm -rf $OBJ/compat/sparc64/sparc/external/bsd/jemalloc*" 41 1.359 martin and "rm $OBJ/compat/sparc64/sparc/lib/libc/jemalloc.*". 42 1.358 martin 43 1.357 christos 20240817: 44 1.357 christos Update builds will require cleaning in src/external/historical/nawk/bin 45 1.357 christos in order to remove the awk binary since now there is a subdirectory 46 1.357 christos called awk. 47 1.358 martin 48 1.355 martin 20240812: 49 1.355 martin Update builds will require removing the tools objdir for gdb 50 1.355 martin if building with MKCROSSGDB=yes. All architectures use gdb.old 51 1.355 martin now. 52 1.356 riastrad 53 1.354 martin 20240630: 54 1.353 martin Update builds will require removing the tools objdir for binutils 55 1.353 martin (as most architectures should use binutils.old now). 56 1.353 martin 57 1.352 kre 20240610: 58 1.352 kre Update builds are likely to require removing the objdir for 59 1.352 kre distrib/<arch>/cdroms - or at least references to libarchive 60 1.352 kre from within there after the recent libarchive update. 61 1.352 kre 62 1.350 riastrad 20240504: 63 1.350 riastrad Update builds on x86 require making the `cleandir' target in 64 1.350 riastrad lib/libm, or deleting the objdir for lib/libm. 65 1.350 riastrad 66 1.349 maya 20240423: 67 1.349 maya Update builds with x11 may fail after switching to Mesa 21. 68 1.349 maya 69 1.346 riastrad 20240410: 70 1.346 riastrad Update builds may require manually deleting 71 1.346 riastrad $DESTDIR/var/run/named (and, potentially, 72 1.346 riastrad $DESTDIR/var/run/lwresd) in order to avoid checkflist failure. 73 1.346 riastrad 74 1.347 nia 20240409: 75 1.347 nia 32-bit compatibility libraries were moved into the base32 76 1.347 nia and debug32 sets. HTML man pages were moved into the manhtml set. 77 1.347 nia 78 1.343 riastrad 20230828: 79 1.343 riastrad If: 80 1.343 riastrad - you updated to current and ran postinstall between 20230826 81 1.343 riastrad and 20230828 inclusive, and 82 1.343 riastrad - you are not using anything outside the base system to 83 1.343 riastrad populate /etc/openssl/certs (e.g., manually adding 84 1.343 riastrad certificates or using ca-certificates or mozilla-rootcerts or 85 1.343 riastrad mozilla-rootcerts-openssl from pkgsrc), 86 1.343 riastrad delete /etc/openssl/certs and rerun postinstall or just 87 1.343 riastrad `certctl rehash'. 88 1.343 riastrad 89 1.343 riastrad Otherwise, certctl(8) will think someone else has left 90 1.343 riastrad /etc/openssl/certs in the way and will avoid clobbering it on 91 1.343 riastrad upgrade from older NetBSD. 92 1.343 riastrad 93 1.341 lukem 20230718: 94 1.341 lukem build.sh will use mk.conf in the same directory as build.sh instead 95 1.341 lukem of /etc/mk.conf, unless MAKECONF is already defined in the environment. 96 1.341 lukem 97 1.342 martin 20230714: 98 1.342 martin Import of gcc 10.5 requires a clean build of at least tools/gcc 99 1.342 martin and external/gpl3/gcc* object directories. An update build 100 1.342 martin without cleaning will result in obscure failures in rare corner 101 1.342 martin cases. 102 1.342 martin 103 1.339 martin 20230604: 104 1.339 martin Building native kernels with the installed make(1) instead of 105 1.339 martin the $TOOLDIR/bin/nbmake-${arch} wrapper will fail if userland 106 1.339 martin has not been updated. Note that this is an unsupported build 107 1.339 martin configuration (but usually works if userland is -current enough). 108 1.338 lukem 109 1.338 lukem 20230523: 110 1.338 lukem ctfmerge was fixed as macOS host tool. This may require a clean tools 111 1.338 lukem rebuild to detect the update to tools/compat/configure. 112 1.338 lukem 113 1.340 martin 20230515: 114 1.340 martin New openssl build requires removal of the crypto/external/bsd/openssl 115 1.345 andvar and tests/crypto/libcrypto subdirectories in the ${OBJDIR} hierarchy. 116 1.340 martin Otherwise test results may be wrong due to wrong "golden" output 117 1.340 martin files being installed. 118 1.340 martin 119 1.337 mrg 20230322: 120 1.337 mrg Fixes for moved /lib/libisns* mean that builds will complain about 121 1.337 mrg ./usr/lib/libisns* being missing until src/lib/libisns is forced 122 1.337 mrg to (re)install the files, including the symlinks. The simplest 123 1.337 mrg way is to clean this subdir before building. 124 1.337 mrg 125 1.336 martin 20230112: 126 1.336 martin New binutils require an updated ld.elf_so. If you are doing 127 1.336 martin (unsupported) in-place self builds (with the -E flag to build.sh), 128 1.336 martin make sure to have installed latest ld.elf_so before you rebuild 129 1.336 martin userland. 130 1.336 martin 131 1.335 chs 20221116: 132 1.335 chs The addition to NetBSD's version of UFS2 of support for extended 133 1.335 chs attributes broke backward compatibility with previous releases 134 1.335 chs of NetBSD, so UFS2 has been restored to being compatible with 135 1.335 chs previous NetBSD releases by disabling extended attributes. 136 1.335 chs (Note that ACLs are implemented as extended attributes, so 137 1.335 chs this changes disables ACLs as well.) 138 1.335 chs 139 1.335 chs Support for UFS2 with extended attributes is now available in a new 140 1.335 chs UFS variant called UFS2ea. If you have created extended attributes 141 1.335 chs in an original UFS2 file system then "fsck -p" will now fail due to 142 1.335 chs the unexpected presence of extended attributes and "fsck -y" will 143 1.335 chs remove all extended attributes. If you wish to preserve extended 144 1.335 chs attributes rather than delete them, there is a utility to convert 145 1.335 chs a UFS2 file system to UFS2ea and leave extended attributes in place, 146 1.335 chs but this should be used with caution since it will preserve any 147 1.335 chs extended attributes that have been corrupted by the backward 148 1.335 chs incompatibility too. 149 1.335 chs 150 1.335 chs If you wish to use a UFS2ea file system as your root file system, 151 1.335 chs then you will need to update your boot loader to a version that 152 1.335 chs supports UFS2ea. 153 1.335 chs 154 1.335 chs For more information, see: 155 1.335 chs https://wiki.netbsd.org/features/UFS2ea 156 1.335 chs 157 1.334 mrg 20221111: 158 1.334 mrg The new libdrm import worsened the conflict issues for the 159 1.334 mrg kdump/ktruss ioctl, and i915 now conflicts with base, and has 160 1.334 mrg been turned off. This will cause update build issues like: 161 1.334 mrg 162 1.334 mrg kdump-ioctl.c:12175:143: error: 'DRM_IOCTL_I915_DESTROY_HEAP' 163 1.334 mrg undeclared here (not in a function); 164 1.334 mrg did you mean 'DRM_IOCTL_MODE_DESTROY_DUMB'? 165 1.334 mrg 166 1.334 mrg You'll need to clean usr.bin/ktruss, usr.bin/kdump, and rescue. 167 1.334 mrg 168 1.331 riastrad 20220921: 169 1.331 riastrad Since the kernel version was bumped to 9.99.100, the bootloader 170 1.333 riastrad must be updated on x86 or EFI boot platforms in order to load 171 1.333 riastrad modules from boot.cfg(5) or interactively at the bootloader 172 1.333 riastrad prompt. 173 1.333 riastrad 174 1.333 riastrad The kernel can still load modules at runtime, with modload(8) 175 1.333 riastrad or modules.conf(5), with no bootloader update. This will not 176 1.333 riastrad affect release branches because it only applies to patch 177 1.333 riastrad numbers >=100. 178 1.333 riastrad 179 1.333 riastrad On x86 (i386 or amd64) with BIOS boot, this requires copying a 180 1.333 riastrad new /usr/mdec/boot to /boot. You can build this in the destdir 181 1.333 riastrad by running `$TOOLDIR/bin/nbmake-$ARCH dependall install' in 182 1.333 riastrad sys/arch/i386/stand. 183 1.333 riastrad 184 1.333 riastrad On platforms with EFI boot (including x86 with EFI boot), this 185 1.333 riastrad requires copying a new /usr/mdec/boot*.efi to the EFI/BOOT/ 186 1.333 riastrad directory on the EFI system partition. The boot*.efi file is: 187 1.333 riastrad 188 1.333 riastrad aarch64 bootaa64.efi 189 1.333 riastrad amd64 bootx64.efi 190 1.333 riastrad arm bootarm.efi (32-bit arm) 191 1.333 riastrad i386 bootx32.efi 192 1.333 riastrad 193 1.333 riastrad You can build this in the destdir by running 194 1.333 riastrad `$TOOLDIR/bin/nbmake-$ARCH dependall install' in 195 1.333 riastrad sys/stand/efiboot/boot*. 196 1.331 riastrad 197 1.330 lukem 20220821: 198 1.330 lukem Support for building extsrc/ has been deprecated. 199 1.330 lukem EXTSRCSRCDIR and MKEXTSRC have been deprecated. 200 1.330 lukem 201 1.329 mrg 20220714: 202 1.329 mrg Updates to xorg-server and associated drivers may cause builds to 203 1.329 mrg fail. Cleaning both DESTDIR and the xorg build tree may be needed. 204 1.329 mrg 205 1.328 martin 20220628: 206 1.328 martin Changes in the build of src/games/robots require a clean build 207 1.328 martin of that program. 208 1.328 martin 209 1.324 martin 20211116: 210 1.324 martin Changes in the xorg build require clean obj dirs for external/mit/xorg 211 1.325 martin (or a full clean/non-update build). 212 1.324 martin 213 1.323 nia 20211112: 214 1.323 nia Device tree sources were updated for evbarm. Some device nodes 215 1.323 nia (in particular, ld(4) devices on the ROCKPro64) will be renumbered. 216 1.323 nia 217 1.322 martin 20211014: 218 1.323 nia MKPIE default for aarch64 has changed, a clean build is required. 219 1.322 martin 220 1.321 christos 20210917: 221 1.321 christos Changed MNT_ACLS to default to POSIX1e ACLs instead of NFSv4 222 1.321 christos ACLs, to be compatible with FreeBSD. If you are using NFSv4 ACLs 223 1.321 christos and have "acls" in /etc/fstab you'll need to change it to "nfs4acls". 224 1.321 christos 225 1.319 mrg 20210711: 226 1.319 mrg Updated GMP sources may require cleaning in tools/gmp and/or in 227 1.319 mrg external/lgpl3/gmp/lib, particularly if GCC itself does not build. 228 1.319 mrg 229 1.318 mrg 20210417: 230 1.318 mrg GCC 10 was enabled for several platforms. If builds fail in either 231 1.351 gutterid tools/gcc or external/gpl3/gcc, first try cleaning those objects and 232 1.318 mrg removing the $DESTDIR/usr/include/g++ subdirectory. 233 1.318 mrg 234 1.316 mrg 20201016: 235 1.316 mrg MIPS kernel modules have been disabled until they work.

This 248 1.313 mrg probably requires cleaning the tools/binutils. 249 1.313 mrg 250 1.311 mrg 20200811: 251 1.312 mrg GCC updates may require cleaning the objdir. This may occur 252 1.312 mrg due to GCC 7.5 update, GCC 8.4 move to gcc.old, or the upcoming 253 1.312 mrg GCC 9 upgrade. 254 1.311 mrg 255 1.309 christos 20200614: 256 1.310 christos blacklist* has been renamed to blocklist*. postinstall(8) 257 1.332 gutterid should handle the migration. 258 1.309 christos 259 1.308 christos 20200601: 260 1.308 christos Due to a mistake in LIBISPRIVATE handling, .so libraries were 261 1.308 christos created in the build directories and need cleaning. 262 1.308 christos 263 1.307 mrg 20200311: 264 1.307 mrg GCC 8 ports will need cleaning in src/tools/gcc and 265 1.307 mrg src/external/gpl3/gcc due to GCC 8.4 update. 266 1.307 mrg 267 1.306 christos 20191118: 268 1.306 christos More architectures were switched to gcc8: 269 1.306 christos i386, ia64 powerpc64, sparc, sparc64, arm 270 1.306 christos The same comments as in 20191022 apply. 271 1.306 christos 272 1.305 martin 20191112: 273 1.305 martin The LLVM update requires a clean rebuild for all architectures using 274 1.305 martin LLVM during the tools build phase (i386, amd64, aarch64). 275 1.305 martin 276 1.304 martin 20191022: 277 1.304 martin Ports amd64 and aarch64 switched to GCC 8.3 by default. 278 1.304 martin In-place ("expert mode", build.sh -E) builds are not supported 279 1.304 martin when going from a GCC 7 userland to GCC 8.

Update builds are likely to fail. 384 1.299 mrg 385 1.1 abs Hints for a more successful build: 386 1.1 abs ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 387 1.123 jmc Use build.sh, but do not use its "expert mode": 388 1.132 jmmv This will automatically build the tools in the 389 1.123 jmc correct order, and it will keep the tools and the 390 1.123 jmc new build products from interfering with the running 391 1.123 jmc system. This will allow you to ignore most of the 392 1.123 jmc other advice in this file. 393 1.2 mrg Build a new kernel first: 394 1.2 mrg This makes sure that any new system calls or features 395 1.2 mrg expected by the new userland will be present. This 396 1.2 mrg helps to avoid critical errors when upgrading. 397 1.1 abs Use object directories: 398 1.1 abs This helps to keep stale object 399 1.1 abs files from polluting the build if a Makefile "forgets" 400 1.1 abs about one. It also makes it easier to clean up after 401 1.1 abs a build. It's also necessary if you want to use the 402 1.1 abs same source tree for multiple machines. 403 1.123 jmc To use object directories with build.sh: 404 1.123 jmc a) invoke build.sh with the "-M" or "-O" options. 405 1.123 jmc To use object directories without using build.sh: 406 1.1 abs a) cd /usr/src ; make cleandir 407 1.2 mrg b) Add "OBJMACHINE=yes" to /etc/mk.conf 408 1.2 mrg c) Add "MKOBJDIRS=yes" to /etc/mk.conf 409 1.1 abs d) cd /usr/src ; make build 410 1.2 mrg Note that running "make obj" in a directory will create 411 1.2 mrg in obj.$MACHINE directory. 412 1.1 abs Build to a DESTDIR: 413 1.123 jmc This helps to keep old installed files (especially libraries) 414 1.123 jmc from interfering with the new build. 415 1.123 jmc To build to a DESTDIR with build.sh, use the "-D" option. 416 1.123 jmc To build to a DESTDIR without using build.sh, set the DESTDIR 417 1.123 jmc environment variable before running make build. It should be 418 1.123 jmc set to the pathname of an initially empty directory. 419 1.123 jmc Problems: if you do not use build.sh, you might need to 420 1.123 jmc update critical utilities without using DESTDIR since 421 1.123 jmc nothing is executed from what is installed in DESTDIR. 422 1.123 jmc (See critical utils, below.) 423 1.1 abs Build often: 424 1.1 abs This keeps critical utilities current enough to not choke 425 1.1 abs on any other part of the source tree that depends on up to 426 1.123 jmc date functionality.
