BUILDING revision 1.46
1 BUILDING(8) NetBSD System Manager's Manual BUILDING(8) 2 3 NAME 4 BUILDING - Procedure for building NetBSD from source code. 5 6 STATUS 7 This document is a work-in-progress. As such, the information described 8 here may not match the reality of the build system as of this writing. 9 Once this document is completely in sync with reality, this paragraph 10 will be removed. 11 12 Discrepancies between this documentation and the current reality of 13 implementation are noted specially, as with the note below: 14 15 Note: This document applies only to platforms which use the new toolchain 16 as indicated by the default setting of TOOLCHAIN_MISSING in <bsd.own.mk>. 17 Platforms which have not yet been switched to the new toolchain should 18 continue building traditionally, using the notes specified in the file 19 UPDATING. 20 21 REQUIREMENTS 22 NetBSD is designed to be buildable on most POSIX-compliant host systems. 23 The basic build procedure is the same whether compiling natively (on the 24 same NetBSD architecture) or cross compiling (on another architecture or 25 OS). 26 27 This source tree contains a special subtree, ``tools'', which uses the 28 host system to create a build toolchain for the target architecture. The 29 host system must have at least C and C++ compilers in order to create the 30 toolchain (make is not required); all other tools are created as part of 31 the NetBSD build process. 32 33 Note: A couple of host toolchain components are not yet available 34 in the tools directory. Also, some tools use non-POSIX, non-ANSI C 35 extensions and need to be standardized. As a result, cross-compil- 36 ing from systems other than NetBSD is not currently supported. 37 38 FILES 39 Source tree layout 40 doc/BUILDING.mdoc 41 This document (in -mdoc troff format; the original copy). 42 43 BUILDING This document (in plaintext). 44 45 Makefile The main Makefile for NetBSD; should only be run for 46 native builds with an appropriately up-to-date version of 47 NetBSD make(1). (For building from out-of-date systems or 48 on a non-native host, see the build.sh shell script.) 49 50 UPDATING Special notes for updating from an earlier revision of 51 NetBSD. It is important to read this file before every 52 build of an updated source tree. 53 54 build.sh Bourne-compatible shell script used for building the host 55 build tools and the NetBSD system from scratch. Can be 56 used for both native and cross builds, and should be used 57 instead of make(1) for any source tree that is updated and 58 recompiled regularly. 59 60 crypto/dist/, dist/, gnu/dist/ 61 Sources imported verbatim from third parties, without man- 62 gling the existing build structure. Other source trees in 63 bin through usr.sbin use the NetBSD make(1) ``reachover'' 64 Makefile semantics when building these programs for a 65 native host. 66 67 distrib/, etc/ 68 Sources for items used when making a full release snap- 69 shot, such as files installed in DESTDIR/etc on the desti- 70 nation system, boot media, and release notes. 71 72 regress/ Regression test harness. Can be cross-compiled, but only 73 run natively. 74 75 sys/ NetBSD kernel sources. 76 77 tools/ ``Reachover'' build structure for the host build tools. 78 This has a special method of determining out-of-date sta- 79 tus. 80 81 bin/ ... usr.sbin/ 82 Sources to the NetBSD userland (non-kernel) programs. If 83 any of these directories are missing, they will be skipped 84 during the build. 85 86 Build tree layout 87 The NetBSD build tree is described in hier(7), and the release layout is 88 described in release(7). 89 90 CONFIGURATION 91 Environment variables 92 Several environment variables control the behaviour of NetBSD builds. 93 94 MACHINE Machine type. 95 96 MACHINE_ARCH Machine architecture. 97 98 MAKE Path name to invoke make(1) as. 99 100 MAKEFLAGS Flags to invoke make(1) with. 101 102 MAKEOBJDIR Directory to use as the .OBJDIR for the current direc- 103 tory. Used only if MAKEOBJDIRPREFIX is not defined. 104 MAKEOBJDIR can only be provided in the environment or 105 via the -O flag of build.sh. 106 107 MAKEOBJDIRPREFIX Top level directory of the object directory tree. If 108 this is defined, ${MAKEOBJDIRPREFIX}/${.CURDIR} is used 109 as the .OBJDIR for the current directory. The current 110 directory may be read only. MAKEOBJDIRPREFIX can only 111 be provided in the environment or via the -M flag of 112 build.sh. 113 114 "make" variables 115 Several variables control the behavior of NetBSD builds. Unless other- 116 wise specified, these variables may be set in either the process environ- 117 ment or the make(1) configuration file specified by MAKECONF. 118 119 BUILDID Identifier for the build. The identifier will be appended to 120 object directory names, and can be consulted in the make(1) 121 configuration file in order to set additional build parame- 122 ters, such as compiler flags. 123 124 DESTDIR Directory to contain the built NetBSD system. If set, spe- 125 cial options are passed to the compilation tools to prevent 126 their default use of the host system's /usr/include, 127 /usr/lib, and so forth. This pathname should not end with a 128 slash (/) character (for installation into the system's root 129 directory, set DESTDIR to an empty string). The directory 130 must reside on a file system which supports long file names 131 and hard links. 132 133 Default: Empty string if USETOOLS is ``yes''; unset other- 134 wise. 135 136 Note: build.sh will provide a default of destdir.MACHINE (in 137 the top-level .OBJDIR) unless run in `expert' mode 138 139 MAKECONF The name of the make(1) configuration file. Only settable in 140 the process environment. 141 142 Default: ``/etc/mk.conf'' 143 144 MAKEVERBOSE 145 Level of verbosity of status messages. Supported values: 146 147 0 No descriptive messages are shown. 148 149 1 Descriptive messages are shown. 150 151 2 Descriptive messages (prefixed with a `#') and command 152 output is not suppressed. 153 154 Default: 2 155 156 MKCATPAGES Can be set to ``yes'' or ``no''. Indicates whether prefor- 157 matted plaintext manual pages will be created during a build. 158 159 Default: ``yes'' 160 161 MKCRYPTO Can be set to ``yes'' or ``no''. Indicates whether crypto- 162 graphic code will be included in a build; provided for the 163 benefit of countries that do not allow strong cryptography. 164 Will not affect use of the standard low-security password 165 encryption system, crypt(3). 166 167 Default: ``yes'' 168 169 MKDOC Can be set to ``yes'' or ``no''. Indicates whether system 170 documentation destined for DESTDIR/usr/share/doc will be 171 installed during a build. 172 173 Default: ``yes'' 174 175 MKHOSTOBJ Can be set to ``yes'' or ``no''. If set to ``yes'', then for 176 programs intended to be run on the compile host, the name, 177 release, and architecture of the host operating system will 178 be suffixed to the name of the object directory created by 179 ``make obj''. (This allows multiple host systems to compile 180 NetBSD for a single target.) If set to ``no'', then programs 181 built to be run on the compile host will use the same object 182 directory names as programs built to be run on the target. 183 184 Default: ``no'' 185 186 MKINFO Can be set to ``yes'' or ``no''. Indicates whether GNU Info 187 files, used for the documentation for most of the compilation 188 tools, will be created and installed during a build. 189 190 Default: ``yes'' 191 192 MKLINT Can be set to ``yes'' or ``no''. Indicates whether lint(1) 193 will be run against portions of the NetBSD source code during 194 the build, and whether lint libraries will be installed into 195 DESTDIR/usr/libdata/lint. 196 197 Default: ``yes'' 198 199 MKMAN Can be set to ``yes'' or ``no''. Indicates whether manual 200 pages will be installed during a build. 201 202 Default: ``yes'' 203 204 MKNLS Can be set to ``yes'' or ``no''. Indicates whether Native 205 Language System locale zone files will be compiled and 206 installed during a build. 207 208 Default: ``yes'' 209 210 MKOBJ Can be set to ``yes'' or ``no''. Indicates whether object 211 directories will be created when running ``make obj''. If 212 set to ``no'', then all built files will be located inside 213 the regular source tree. 214 215 Default: ``yes'' 216 217 MKPIC Can be set to ``yes'' or ``no''. Indicates whether shared 218 objects and libraries will be created and installed during a 219 build. If set to ``no'', the entire built system will be 220 statically linked. 221 222 Default: Platform dependent. As of this writing, all plat- 223 forms except sh3 default to ``yes''. 224 225 MKPICINSTALL 226 Can be set to ``yes'' or ``no''. Indicates whether the ar(1) 227 format libraries (lib*_pic.a), used to generate shared 228 libraries, are installed during a build. 229 230 Default: ``yes'' 231 232 MKPROFILE Can be set to ``yes'' or ``no''. Indicates whether profiled 233 libraries (lib*_p.a) will be built and installed during a 234 build. 235 236 Default: ``yes''; however, some platforms turn off MKPROFILE 237 by default at times due to toolchain problems with profiled 238 code. 239 240 MKSHARE Can be set to ``yes'' or ``no''. Indicates whether files 241 destined to reside in DESTDIR/usr/share will be built and 242 installed during a build. If set to ``no'', then all of 243 MKCATPAGES, MKDOC, MKINFO, MKMAN, and MKNLS will be set to 244 ``no'' unconditionally. 245 246 Default: ``yes'' 247 248 MKUNPRIVED Can be set to ``yes'' or ``no''. Indicates whether an 249 unprivileged install will occur. The user, group, permis- 250 sions, and file flags, will not be set on the installed item; 251 instead the information will be appended to a file called 252 METALOG in DESTDIR. The contents of METALOG is used during 253 the generation of the distribution tar files to ensure that 254 the appropriate file ownership is stored. 255 256 Default: ``no'' 257 258 MKUPDATE Can be set to ``yes'' or ``no''. Indicates whether all 259 install operations intended to write to DESTDIR will compare 260 file timestamps before installing, and skip the install phase 261 if the destination files are up-to-date. This also has 262 implications on full builds (see next subsection). 263 264 Default: ``no'' 265 266 TOOLDIR Directory to hold the host tools, once built. This directory 267 should be unique to a given host system and NetBSD source 268 tree. (However, multiple targets may share the same TOOLDIR; 269 the target-dependent files have unique names.) If unset, a 270 default based on the uname(1) information of the host plat- 271 form will be created in the .OBJDIR of src. 272 273 Default: Unset. 274 275 USETOOLS Indicates whether the tools specified by TOOLDIR should be 276 used as part of a build in progress. Must be set to ``yes'' 277 if cross-compiling. 278 279 yes Use the tools from TOOLDIR. 280 281 no Do not use the tools from TOOLDIR, but refuse to build 282 native compilation tool components that are version- 283 specific for that tool. 284 285 never Do not use the tools from TOOLDIR, even when building 286 native tool components. This is similar to the tradi- 287 tional NetBSD build method, but does not verify that 288 the compilation tools in use are up-to-date enough in 289 order to build the tree successfully. This may cause 290 build or runtime problems when building the whole 291 NetBSD source tree. 292 293 Default: ``yes'' if building all or part of a whole NetBSD 294 source tree (detected automatically); ``no'' otherwise (to 295 preserve traditional semantics of the <bsd.*.mk> make(1) 296 include files). 297 298 "make" variables for full builds 299 These variables only affect the top level ``Makefile'' and do not affect 300 manually building subtrees of the NetBSD source code. 301 302 INSTALLWORLDDIR Location for the ``make installworld'' target to install 303 to. 304 305 Default: ``/'' 306 307 MKOBJDIRS Can be set to ``yes'' or ``no''. Indicates whether 308 object directories will be created automatically (via a 309 ``make obj'' pass) at the start of a build. 310 311 Default: ``no'' 312 313 MKUPDATE Can be set to ``yes'' or ``no''. If set, then in addi- 314 tion to the effects described for MKUPDATE=yes above, 315 this implies the effects of NOCLEANDIR (i.e., ``make 316 cleandir'' is avoided). 317 318 Default: ``no'' 319 320 NBUILDJOBS Now obsolete. Use the make(1) option -j, instead (see 321 below) 322 323 Default: Unset. 324 325 NOCLEANDIR If set, avoids the ``make cleandir'' phase of a full 326 build. This has the effect of allowing only changed 327 files in a source tree to be recompiled. This can speed 328 up builds when updating only a few files in the tree. 329 330 Default: Unset. 331 332 NODISTRIBDIRS If set, avoids the ``make distrib-dirs'' phase of a full 333 build. This skips running mtree(8) on DESTDIR, useful 334 on systems where building as an unprivileged user, or 335 where it is known that the system-wide mtree files have 336 not changed. 337 338 Default: Unset. 339 340 NOINCLUDES If set, avoids the ``make includes'' phase of a full 341 build. This has the effect of preventing make(1) from 342 thinking that some programs are out-of-date simply 343 because the system include files have changed. However, 344 this option should not be used when updating the entire 345 NetBSD source tree arbitrarily; it is suggested to use 346 MKUPDATE=yes in that case. 347 348 Default: Unset. 349 350 RELEASEDIR If set, specifies the directory to which a release(7) 351 layout will be written at the end of a ``make release''. 352 353 Default: Unset. 354 355 Note: build.sh will provide a default of releasedir (in 356 the top-level .OBJDIR) unless run in `expert' mode 357 358 BUILDING 359 "make" command line options 360 This is only a summary of options available to make(1); only the options 361 used most frequently with NetBSD builds are listed here. 362 363 -j njob Run up to njob make(1) subjobs in parallel. Makefiles should 364 use .WAIT or have explicit dependancies as necessary to 365 enforce build ordering. If you see build failures with -j, 366 please save complete build logs so the failures can be ana- 367 lyzed. 368 369 -m dir Specify the default directory for searching for system Make- 370 file segments, mainly the <bsd.*.mk> files. When building any 371 full NetBSD source tree, this should be set to the 372 ``share/mk'' directory in the source tree. (This is set auto- 373 matically when building from the top level.) 374 375 -n Display the commands that would have been executed, but do not 376 actually execute them. This will still cause recursion to 377 take place. 378 379 -v var Print make(1)'s idea of the value of var. Does not build any 380 targets. 381 382 var=value Set the variable var to value, overriding any setting speci- 383 fied by the process environment, the MAKECONF configuration 384 file, or the system Makefile segments. 385 386 "make" targets 387 These default targets may be built by running make(1) in any subtree of 388 the NetBSD source code. It is recommended that none of these be used 389 from the top level Makefile; as a specific exception, ``make obj'' and 390 ``make cleandir'' are useful in that context. 391 392 all Build programs, libraries, and preformatted documentation. 393 394 clean Remove program and library object code files. 395 396 cleandir Same as clean, but also remove preformatted documentation, 397 dependency files generated by ``make depend'', and any other 398 files known to be created at build time. ``make distclean'' 399 may be used as a synonym, for familiarity with a similar well- 400 known convention. 401 402 depend Create dependency files (.depend) containing more detailed 403 information about the dependencies of source code on header 404 files. Allows programs to be recompiled automatically when a 405 dependency changes. 406 407 dependall Does a ``make depend'' immediately followed by a ``make all''. 408 This improves cache locality of the build since both passes 409 read the source files in their entirety. 410 411 includes Build and install system header files. Typically needed 412 before any system libraries or programs can be built. 413 414 install Install programs, libraries, and documentation into DESTDIR. 415 Few files will be installed to DESTDIR/dev, DESTDIR/etc, 416 DESTDIR/root or DESTDIR/var in order to prevent user supplied 417 configuration data from being overwritten. 418 419 lint Run lint(1) against the C source code, where appropriate, and 420 generate system-installed lint libraries. 421 422 obj Create object directories to be used for built files, instead 423 of building directly in the source tree. 424 425 tags Create ctags(1) searchable function lists usable by the ex(1) 426 and vi(1) text editors. 427 428 "make" targets for the top level 429 Additional make(1) targets are usable specifically from the top source 430 level to facilitate building the entire NetBSD source tree. 431 432 build Build the entire NetBSD system. This orders portions of 433 the source tree such that prerequisites will be built in 434 the proper order. 435 436 distribution Do a ``make build'', and then install a full distribution 437 into DESTDIR, including files in DESTDIR/dev, DESTDIR/etc, 438 DESTDIR/root and DESTDIR/var. 439 440 buildworld As per ``make distribution'', except that it ensures that 441 DESTDIR is not the root directory. 442 443 installworld Install the distribution from DESTDIR to INSTALLWORLDDIR 444 (which defaults to the root directory). Ensures that 445 INSTALLWORLDDIR is the not root directory if cross compil- 446 ing. 447 448 Note: It is highly recommended that you upgrade your kernel 449 and reboot before performing this operation. 450 451 sets Create distribution sets from DESTDIR into 452 RELEASEDIR/MACHINE/binary/sets. Should be run after ``make 453 distribution'' (as ``make build'' does not install all of 454 the required files). 455 456 sourcesets Create source sets of the source tree into 457 RELEASEDIR/source/sets. 458 459 release Do a ``make distribution'', build kernels, distribution 460 media, and install sets (this as per ``make sets''), and 461 then package the system into a standard release layout as 462 described by release(7). This requires that RELEASEDIR be 463 set (see above). 464 465 regression-tests 466 Can only be run after building the regression tests in the 467 directory ``regress''. Runs the compiled regression tests 468 on the local host. 469 470 The "build.sh" script 471 This script file is a Bourne shell script designed to build the entire 472 NetBSD system on any host with a Bourne shell in /bin/sh, including many 473 that are not POSIX compliant. Note that if a host system's /bin/sh is 474 unusually old and broken, the Korn Shell (/bin/ksh), if available, may be 475 a usable alternative. 476 477 All cross-compile builds, and most native builds, of the entire system 478 should make use of build.sh rather than just running ``make''. This way, 479 the make(1) program will be bootstrapped properly, in case the host sys- 480 tem has an older or incompatible ``make'' program. 481 482 When compiling the entire system via build.sh, many make(1) variables are 483 set for you in order to help encapsulate the build process. In the list 484 of options below, variables that are automatically set by build.sh are 485 noted where applicable. 486 487 The following operations are supported by build.sh: 488 489 build Build the system as per ``make build''. This option 490 implies the obj and tools operations. 491 492 distribution Build a full distribution as per ``make distribution''. 493 This option implies the build operation. 494 495 release Build a full release as per ``make release''. This option 496 implies the distribution operation. 497 498 makewrapper Create the nbmake-MACHINE wrapper. This operation is auto- 499 matically performed for any of the other operations. 500 501 obj Perform ``make obj''. 502 503 tools Build and install the host tools from src/tools. 504 505 install=idir Install the contents of DESTDIR to idir, using ``make 506 installworld''. 507 508 kernel=kconf Build a new kernel. The kconf argument is the name of a 509 configuration file suitable for use by config(8). If kconf 510 does not contain any `/' characters, the configuration file 511 is expected to be found in the KERNCONFDIR directory, which 512 is typically sys/arch/MACHINE/conf. The new kernel will be 513 built in a subdirectory of KERNOBJDIR, which is typically 514 sys/arch/MACHINE/compile or an associated object directory. 515 In order to ensure that the kernel is built using up-to- 516 date tools, it is strongly recommended that the tools be 517 rebuilt (using the tools operation). 518 519 releasekernel=kconf 520 Install a gzip(1)ed copy of the kernel built by 521 kernel=kconf into RELEASEDIR/MACHINE/binary/kernel, usually 522 as netbsd-kconf.gz, although the ``netbsd'' prefix is 523 determined from the ``config'' directives in kconf. 524 525 sets Perform ``make sets''. 526 527 sourcesets Perform ``make sourcesets''. 528 529 The following command line options alter the behaviour of the above oper- 530 ations: The following command line options alter the behaviour of the 531 build.sh operations described above: 532 533 -a arch Set the value of MACHINE_ARCH to arch. 534 535 -B buildid 536 Set the value of BUILDID to buildid. This will also append the 537 build idenfitier to the name of the ``make'' wrapper script so 538 that the resulting name is of the form 539 ``nbmake-MACHINE-BUILDID''. 540 541 -D dest Set the value of DESTDIR to dest. 542 543 -E Set `expert' mode. This overrides various sanity checks, and 544 allows: DESTDIR does not have to be set to a non-root path for 545 builds, and MKUNPRIVED=yes does not have to be set when build- 546 ing as a non-root user. 547 548 Note: It is highly recommended that you know what you are doing 549 when you use this option. 550 551 -j njob Passed through to make(1). Makefiles should use .WAIT or have 552 explicit dependancies as necessary to enforce build ordering. 553 If you see build failures with -j, please save complete build 554 logs so the failures can be analyzed. 555 556 -M obj Set MAKEOBJDIRPREFIX to obj. Unsets MAKEOBJDIR. 557 558 -m mach Set the value of MACHINE to mach. This will also override any 559 value of MACHINE_ARCH in the process environment with a value 560 deduced from mach, unless -a is specified, or mach is a special 561 case listed below. All cross builds require -m, but if unset 562 on a NetBSD host, the host's value of MACHINE will be detected 563 and used automatically. 564 565 Some machines support multiple values for MACHINE_ARCH. For a 566 given value of mach, the following MACHINE and MACHINE_ARCH 567 values will result: 568 569 mach MACHINE MACHINE_ARCH 570 evbmips evbmips (not set) 571 evbmips-eb evbmips mipseb 572 evbmips-el evbmips mipsel 573 evbsh3 evbsh3 (not set) 574 evbsh3-eb evbsh3 sh3eb 575 evbsh3-el evbsh3 sh3el 576 sbmips sbmips (not set) 577 sbmips-eb sbmips mipseb 578 sbmips-el sbmips mipsel 579 580 -N noiselevel 581 Set the ``noisyness'' level of the build, by setting 582 MAKEVERBOSE to noiselevel. 583 584 -n Show the commands that would be executed by build.sh, but do 585 not make any changes. This is similar in concept to ``make 586 -n''. 587 588 -O obj Create an appropriate transform macro for MAKEOBJDIR that will 589 place the built object files under obj. For instance, a set- 590 ting of /usr/obj will place build-time files under 591 /usr/obj/bin, /usr/obj/lib, /usr/obj/usr.bin, and so forth. 592 Unsets MAKEOBJDIRPREFIX. 593 594 -o Set the value of MKOBJDIRS to ``no''. Otherwise, it will be 595 automatically set to ``yes'' (which is opposite to the default 596 behaviour). 597 598 -R rel Set the value of RELEASEDIR to rel. 599 600 -r Remove the contents of DESTDIR and TOOLDIR before building 601 (provides a clean starting point). This will skip deleting 602 DESTDIR if building on a native system to the root directory. 603 604 -T tools Set the value of TOOLDIR to tools. If set, the bootstrap 605 ``make'' will only be rebuilt as needed (when the source files 606 for make(1) change). 607 608 -U Set MKUNPRIVED=yes. 609 610 -u Set MKUPDATE=yes. 611 612 -V var=[value] 613 Set the environment variable var to an optional value. This is 614 propagated to the nbmake wrapper. 615 616 -w wrapper 617 Create the nbmake wrapper script (see below) in a custom loca- 618 tion, specified by wrapper. This allows, for instance, to 619 place the wrapper in PATH automatically. Note that wrapper is 620 the full name of the file, not just a directory name. 621 622 -Z var Unset ("zap") the environment variable var. This is propagated 623 to the nbmake wrapper. 624 625 The "nbmake-MACHINE" wrapper script 626 If using the build.sh script to build NetBSD, a nbmake-MACHINE script 627 will be created in TOOLDIR/bin upon the first build to assist in building 628 subtrees on a cross-compile host. 629 630 nbmake-MACHINE can be invoked in lieu of make(1), and will instead call 631 the up-to-date version of ``nbmake'' installed into TOOLDIR/bin with sev- 632 eral key variables pre-set, including MACHINE, MACHINE_ARCH, and TOOLDIR. 633 build.sh will also set variables specified with -V, and unset variables 634 specified with -Z. 635 636 This script can be symlinked into a directory listed in PATH, or called 637 with an absolute path. 638 639 EXAMPLES 640 1. % ./build.sh tools kernel=GENERIC 641 642 Build a new toolchain, and use the new toolchain to configure and 643 build a new GENERIC kernel. 644 645 2. % ./build.sh -U distribution 646 647 Using unprivileged mode, build a complete distribution to a DESTDIR 648 directory that build.sh selects (and will display). 649 650 3. # ./build.sh -U install=/ 651 652 As root, install to / the distribution that was built by example 2. 653 Even though this is run as root, -U is required so that the permis- 654 sions stored in DESTDIR/METALOG are correctly applied to the files 655 as they're copied to /. 656 657 4. % ./build.sh -U -u release 658 659 Using unprivileged mode, build a complete release to DESTDIR and 660 RELEASEDIR directories that build.sh selects (and will display). 661 MKUPDATE=yes (-u) is set to prevent the ``make cleandir'', so that 662 if this is run after example 2, it doesn't need to redo that portion 663 of the release build. 664 665 OBSOLETE VARIABLES 666 NBUILDJOBS Use the make(1) option -j, instead. 667 668 USE_NEW_TOOLCHAIN 669 The new toolchain is now the default. To disable, use 670 TOOLCHAIN_MISSING=yes. 671 672 SEE ALSO 673 make(1), hier(7), release(7) 674 675 HISTORY 676 The build.sh based build scheme was introduced for NetBSD 1.6 as 677 USE_NEW_TOOLCHAIN, and re-worked to TOOLCHAIN_MISSING after that. 678 679 BUGS 680 A few platforms are not yet using this build system. 681 682 NetBSD October 25, 2003 NetBSD 683
