1BUILDING(8) System Manager's Manual BUILDING(8) 2 3NNAAMMEE 4 BBUUIILLDDIINNGG -- Procedure for building NetBSD from source code. 5 6RREEQQUUIIRREEMMEENNTTSS 7 NetBSD is designed to be buildable on most POSIX-compliant host systems. 8 The basic build procedure is the same whether compiling _n_a_t_i_v_e_l_y (on the 9 same NetBSD architecture) or _c_r_o_s_s _c_o_m_p_i_l_i_n_g (on another architecture or 10 OS). 11 12 This source tree contains a special subtree, ``tools'', which uses the 13 host system to create a build toolchain for the target architecture. The 14 host system must have at least C and C++ compilers in order to create the 15 toolchain (mmaakkee is not required); all other tools are created as part of 16 the NetBSD build process. (See the environment variables section below 17 if you need to override or manually select your compilers.) 18 19FFIILLEESS 20 SSoouurrccee ttrreeee llaayyoouutt 21 ddoocc//BBUUIILLDDIINNGG..mmddoocc 22 This document (in -mdoc troff format; the original copy). 23 24 BBUUIILLDDIINNGG This document (in plaintext). 25 26 ttoooollss//ccoommppaatt//RREEAADDMMEE 27 Special notes for cross-hosting a NetBSD build on non- 28 NetBSD platforms. 29 30 MMaakkeeffiillee The main Makefile for NetBSD; should only be run for 31 native builds with an appropriately up-to-date version of 32 NetBSD make(1). (For building from out-of-date systems or 33 on a non-native host, see the bbuuiilldd..sshh shell script.) 34 35 UUPPDDAATTIINNGG Special notes for updating from an earlier revision of 36 NetBSD. It is important to read this file before every 37 build of an updated source tree. 38 39 bbuuiilldd..sshh Bourne-compatible shell script used for building the host 40 build tools and the NetBSD system from scratch. Can be 41 used for both native and cross builds, and should be used 42 instead of make(1) for any source tree that is updated and 43 recompiled regularly. 44 45 ccrryyppttoo//ddiisstt//, ddiisstt//, ggnnuu//ddiisstt// 46 Sources imported verbatim from third parties, without 47 mangling the existing build structure. Other source trees 48 in bbiinn through uussrr..ssbbiinn use the NetBSD make(1) 49 ``reachover'' Makefile semantics when building these 50 programs for a native host. 51 52 ddiissttrriibb//, eettcc// 53 Sources for items used when making a full release 54 snapshot, such as files installed in DDEESSTTDDIIRR_/_e_t_c on the 55 destination system, boot media, and release notes. 56 57 tteessttss//, rreeggrreessss// 58 Regression test harness. Can be cross-compiled, but only 59 run natively. _t_e_s_t_s_/ uses the atf(7) test framework; 60 _r_e_g_r_e_s_s_/ contains older tests that have not yet been 61 migrated to atf(7). 62 63 ssyyss// NetBSD kernel sources. 64 65 ttoooollss// ``Reachover'' build structure for the host build tools. 66 This has a special method of determining out-of-date 67 status. 68 69 bbiinn// ...... uussrr..ssbbiinn// 70 Sources to the NetBSD userland (non-kernel) programs. If 71 any of these directories are missing, they will be skipped 72 during the build. 73 74 xx1111// ``Reachover'' build structure for X11R6; the source is in 75 XX1111SSRRCCDDIIRR. 76 77 BBuuiilldd ttrreeee llaayyoouutt 78 The NetBSD build tree is described in hier(7), and the release layout is 79 described in release(7). 80 81CCOONNFFIIGGUURRAATTIIOONN 82 EEnnvviirroonnmmeenntt vvaarriiaabblleess 83 Several environment variables control the behaviour of NetBSD builds. 84 85 HHOOSSTT__SSHH Path name to a shell available on the host system and 86 suitable for use during the build. The NetBSD build 87 system requires a modern Bourne-like shell with POSIX- 88 compliant features, and also requires support for the 89 ``local'' keyword to declare local variables in shell 90 functions (which is a widely-implemented but non- 91 standardised feature). 92 93 Depending on the host system, a suitable shell may be 94 _/_b_i_n_/_s_h, _/_u_s_r_/_x_p_g_4_/_b_i_n_/_s_h, _/_b_i_n_/_k_s_h (provided it is a 95 variant of ksh that supports the ``local'' keyword, 96 such as ksh88, but not ksh93), or _/_u_s_r_/_l_o_c_a_l_/_b_i_n_/_b_a_s_h. 97 98 Most parts of the build require HHOOSSTT__SSHH to be an 99 absolute path; however, bbuuiilldd..sshh allows it to be a 100 simple command name, which will be converted to an 101 absolute path by searching the PPAATTHH. 102 103 HHOOSSTT__CCCC Path name to C compiler used to create the toolchain. 104 105 HHOOSSTT__CCXXXX Path name to C++ compiler used to create the toolchain. 106 107 MMAACCHHIINNEE Machine type, e.g., ``macppc''. 108 109 MMAACCHHIINNEE__AARRCCHH Machine architecture, e.g., ``powerpc''. 110 111 MMAAKKEE Path name to invoke make(1) as. 112 113 MMAAKKEEFFLLAAGGSS Flags to invoke make(1) with. Note that bbuuiilldd..sshh 114 ignores the value of MMAAKKEEFFLLAAGGSS passed in the 115 environment, but allows MMAAKKEEFFLLAAGGSS to be set via the --VV 116 option. 117 118 MMAAKKEEOOBBJJDDIIRR Directory to use as the ..OOBBJJDDIIRR for the current 119 directory. The value is subjected to variable 120 expansion by make(1). Typical usage is to set this 121 variable to a value involving the use of 122 `${.CURDIR:S...}' or `${.CURDIR:C...}', to derive the 123 value of ..OOBBJJDDIIRR from the value of ..CCUURRDDIIRR. Used only 124 if MMAAKKEEOOBBJJDDIIRRPPRREEFFIIXX is not defined. MMAAKKEEOOBBJJDDIIRR can be 125 provided only in the environment or via the --OO flag of 126 bbuuiilldd..sshh; it cannot usefully be set inside a Makefile, 127 including _m_k_._c_o_n_f or $${{MMAAKKEECCOONNFF}}. 128 129 MMAAKKEEOOBBJJDDIIRRPPRREEFFIIXX Top level directory of the object directory tree. The 130 value is subjected to variable expansion by make(1). 131 bbuuiilldd..sshh will create the ${MAKEOBJDIRPREFIX} directory 132 if necessary, but if make(1) is used without bbuuiilldd..sshh, 133 then rules in <bsd.obj.mk> will abort the build if the 134 ${MAKEOBJDIRPREFIX} directory does not exist. If the 135 value is defined and valid, then 136 ${MAKEOBJDIRPREFIX}/${.CURDIR} is used as the ..OOBBJJDDIIRR 137 for the current directory. The current directory may 138 be read only. MMAAKKEEOOBBJJDDIIRRPPRREEFFIIXX can be provided only in 139 the environment or via the --MM flag of bbuuiilldd..sshh; it 140 cannot usefully be set inside a Makefile, including 141 _m_k_._c_o_n_f or $${{MMAAKKEECCOONNFF}}. 142 143 ""mmaakkee"" vvaarriiaabblleess 144 Several variables control the behavior of NetBSD builds. Unless 145 otherwise specified, these variables may be set in either the process 146 environment or the make(1) configuration file specified by MMAAKKEECCOONNFF. 147 148 BBUUIILLDDIIDD Identifier for the build. The identifier will be appended to 149 object directory names, and can be consulted in the make(1) 150 configuration file in order to set additional build 151 parameters, such as compiler flags. 152 153 BBUUIILLDDSSEEEEDD GCC uses random numbers when compiling C++ code. This 154 variable seeds the gcc random number generator using the 155 -frandom-seed flag with this value. By default, it is set to 156 NetBSD-(majorversion). Using a fixed value causes C++ 157 binaries to be the same when built from the same sources, 158 resulting in identical (reproducible) builds. Additional 159 information is available in the GCC documentation of 160 -frandom-seed. 161 162 DDEESSTTDDIIRR Directory to contain the built NetBSD system. If set, 163 special options are passed to the compilation tools to 164 prevent their default use of the host system's //uussrr//iinncclluuddee, 165 //uussrr//lliibb, and so forth. This pathname must be an absolute 166 path, and should _n_o_t end with a slash (/) character. (For 167 installation into the system's root directory, set DDEESSTTDDIIRR to 168 an empty string, not to ``/''). The directory must reside on 169 a file system which supports long file names and hard links. 170 171 _D_e_f_a_u_l_t: Empty string if UUSSEETTOOOOLLSS is ``yes''; unset 172 otherwise. 173 174 _N_o_t_e: bbuuiilldd..sshh will provide a default of _d_e_s_t_d_i_r_.MMAACCHHIINNEE (in 175 the top-level ..OOBBJJDDIIRR) unless run in `expert' mode. 176 177 MMAAKKEECCOONNFF The name of the make(1) configuration file. _O_n_l_y _s_e_t_t_a_b_l_e _i_n 178 _t_h_e _p_r_o_c_e_s_s _e_n_v_i_r_o_n_m_e_n_t_. 179 180 _D_e_f_a_u_l_t: ``/etc/mk.conf'' 181 182 MMAAKKEEVVEERRBBOOSSEE 183 Level of verbosity of status messages. Supported values: 184 185 0 No descriptive messages or commands executed by make(1) 186 are shown. 187 188 1 Brief messages are shown describing what is being done, 189 but the actual commands executed by make(1) are not 190 displayed. 191 192 2 Descriptive messages are shown as above (prefixed with a 193 `#'), and ordinary commands performed by make(1) are 194 displayed. 195 196 3 In addition to the above, all commands performed by 197 make(1) are displayed, even if they would ordinarily 198 have been hidden through use of the ``@'' prefix in the 199 relevant makefile. 200 201 4 In addition to the above, commands executed by make(1) 202 are traced through use of the sh(1) ``--xx'' flag. 203 204 _D_e_f_a_u_l_t: 2 205 206 MMKKCCAATTPPAAGGEESS Can be set to ``yes'' or ``no''. Indicates whether 207 preformatted plaintext manual pages will be created during a 208 build. 209 210 _D_e_f_a_u_l_t: ``yes'' 211 212 MMKKCCRRYYPPTTOO Can be set to ``yes'' or ``no''. Indicates whether 213 cryptographic code will be included in a build; provided for 214 the benefit of countries that do not allow strong 215 cryptography. Will not affect use of the standard low- 216 security password encryption system, crypt(3). 217 218 _D_e_f_a_u_l_t: ``yes'' 219 220 MMKKDDOOCC Can be set to ``yes'' or ``no''. Indicates whether system 221 documentation destined for DDEESSTTDDIIRR_/_u_s_r_/_s_h_a_r_e_/_d_o_c will be 222 installed during a build. 223 224 _D_e_f_a_u_l_t: ``yes'' 225 226 MMKKHHTTMMLL Can be set to ``yes'' or ``no''. Indicates whether 227 preformatted HTML manual pages will be built and installed 228 229 _D_e_f_a_u_l_t: ``yes'' 230 231 MMKKHHOOSSTTOOBBJJ Can be set to ``yes'' or ``no''. If set to ``yes'', then for 232 programs intended to be run on the compile host, the name, 233 release, and architecture of the host operating system will 234 be suffixed to the name of the object directory created by 235 ``make obj''. (This allows multiple host systems to compile 236 NetBSD for a single target.) If set to ``no'', then programs 237 built to be run on the compile host will use the same object 238 directory names as programs built to be run on the target. 239 240 _D_e_f_a_u_l_t: ``no'' 241 242 MMKKIINNFFOO Can be set to ``yes'' or ``no''. Indicates whether GNU Info 243 files, used for the documentation for most of the compilation 244 tools, will be created and installed during a build. 245 246 _D_e_f_a_u_l_t: ``yes'' 247 248 MMKKKKMMOODD Can be set to ``yes'' or ``no''. Indicates whether kernel 249 modules are built and installed. 250 251 _D_e_f_a_u_l_t: ``yes'' 252 253 MMKKLLIINNTT Can be set to ``yes'' or ``no''. Indicates whether lint(1) 254 will be run against portions of the NetBSD source code during 255 the build, and whether lint libraries will be installed into 256 DDEESSTTDDIIRR_/_u_s_r_/_l_i_b_d_a_t_a_/_l_i_n_t. 257 258 _D_e_f_a_u_l_t: ``yes'' 259 260 MMKKMMAANN Can be set to ``yes'' or ``no''. Indicates whether manual 261 pages will be installed during a build. 262 263 _D_e_f_a_u_l_t: ``yes'' 264 265 MMKKNNLLSS Can be set to ``yes'' or ``no''. Indicates whether Native 266 Language System locale zone files will be compiled and 267 installed during a build. 268 269 _D_e_f_a_u_l_t: ``yes'' 270 271 MMKKOOBBJJ Can be set to ``yes'' or ``no''. Indicates whether object 272 directories will be created when running ``make obj''. If 273 set to ``no'', then all built files will be located inside 274 the regular source tree. 275 276 _D_e_f_a_u_l_t: ``yes'' 277 278 Note that setting MMKKOOBBJJ to ``no'' is not recommended and may 279 cause problems when updating the tree with cvs(1). 280 281 MMKKPPIICC Can be set to ``yes'' or ``no''. Indicates whether shared 282 objects and libraries will be created and installed during a 283 build. If set to ``no'', the entire built system will be 284 statically linked. 285 286 _D_e_f_a_u_l_t: Platform dependent. As of this writing, all 287 platforms except sshh33 default to ``yes''. 288 289 MMKKPPIICCIINNSSTTAALLLL 290 Can be set to ``yes'' or ``no''. Indicates whether the ar(1) 291 format libraries (lliibb**__ppiicc..aa), used to generate shared 292 libraries, are installed during a build. 293 294 _D_e_f_a_u_l_t: ``yes'' 295 296 MMKKPPRROOFFIILLEE Can be set to ``yes'' or ``no''. Indicates whether profiled 297 libraries (lliibb**__pp..aa) will be built and installed during a 298 build. 299 300 _D_e_f_a_u_l_t: ``yes''; however, some platforms turn off MMKKPPRROOFFIILLEE 301 by default at times due to toolchain problems with profiled 302 code. 303 304 MMKKRREEPPRROO Can be set to ``yes'' or ``no''. Create reproducable builds. 305 This enables different switches to make two builds from the 306 same source tree result in the same build results. 307 308 _D_e_f_a_u_l_t: ``no'' 309 310 MMKKSSHHAARREE Can be set to ``yes'' or ``no''. Indicates whether files 311 destined to reside in DDEESSTTDDIIRR_/_u_s_r_/_s_h_a_r_e will be built and 312 installed during a build. If set to ``no'', then all of 313 MMKKCCAATTPPAAGGEESS, MMKKDDOOCC, MMKKIINNFFOO, MMKKMMAANN, and MMKKNNLLSS will be set to 314 ``no'' unconditionally. 315 316 _D_e_f_a_u_l_t: ``yes'' 317 318 MMKKSSTTRRIIPPIIDDEENNTT 319 Can be set to ``yes'' or ``no''. Indicates whether program 320 binaries and shared libraries should be built to include RCS 321 IDs for use with ident(1). 322 323 _D_e_f_a_u_l_t: ``no'' 324 325 MMKKUUNNPPRRIIVVEEDD Can be set to ``yes'' or ``no''. Indicates whether an 326 unprivileged install will occur. The user, group, 327 permissions, and file flags, will not be set on the installed 328 items; instead the information will be appended to a file 329 called _M_E_T_A_L_O_G in DDEESSTTDDIIRR. The contents of _M_E_T_A_L_O_G are used 330 during the generation of the distribution tar files to ensure 331 that the appropriate file ownership is stored. 332 333 _D_e_f_a_u_l_t: ``no'' 334 335 MMKKUUPPDDAATTEE Can be set to ``yes'' or ``no''. Indicates whether all 336 install operations intended to write to DDEESSTTDDIIRR will compare 337 file timestamps before installing, and skip the install phase 338 if the destination files are up-to-date. This also has 339 implications on full builds (see next subsection). 340 341 _D_e_f_a_u_l_t: ``no'' 342 343 MMKKXX1111 Can be set to ``yes'' or ``no''. Indicates whether X11 is 344 built from XX1111SSRRCCDDIIRR. 345 346 _D_e_f_a_u_l_t: ``no'' 347 348 TTOOOOLLDDIIRR Directory to hold the host tools, once built. If specified, 349 must be an absolute path. This directory should be unique to 350 a given host system and NetBSD source tree. (However, 351 multiple targets may share the same TTOOOOLLDDIIRR; the target- 352 dependent files have unique names.) If unset, a default 353 based on the uname(1) information of the host platform will 354 be created in the ..OOBBJJDDIIRR of _s_r_c. 355 356 _D_e_f_a_u_l_t: Unset. 357 358 UUSSEETTOOOOLLSS Indicates whether the tools specified by TTOOOOLLDDIIRR should be 359 used as part of a build in progress. Must be set to ``yes'' 360 if cross-compiling. 361 362 yyeess Use the tools from TTOOOOLLDDIIRR. 363 364 nnoo Do not use the tools from TTOOOOLLDDIIRR, but refuse to build 365 native compilation tool components that are version- 366 specific for that tool. 367 368 nneevveerr Do not use the tools from TTOOOOLLDDIIRR, even when building 369 native tool components. This is similar to the 370 traditional NetBSD build method, but does _n_o_t verify 371 that the compilation tools in use are up-to-date 372 enough in order to build the tree successfully. This 373 may cause build or runtime problems when building the 374 whole NetBSD source tree. 375 376 _D_e_f_a_u_l_t: ``yes'', unless TTOOOOLLCCHHAAIINN__MMIISSSSIINNGG is set to ``yes''. 377 378 UUSSEETTOOOOLLSS is also set to ``no'' when using <bsd.*.mk> outside 379 the NetBSD source tree. 380 381 XX1111SSRRCCDDIIRR Directory containing the X11R6 source. If specified, must be 382 an absolute path. The main X11R6 source is found in 383 XX1111SSRRCCDDIIRR_/_x_f_r_e_e_/_x_c. 384 385 _D_e_f_a_u_l_t: NNEETTBBSSDDRRCCDDIIRR_/_._._/_x_s_r_c, if that exists; otherwise 386 _/_u_s_r_/_x_s_r_c. 387 388 XX1111FFLLAAVVOOUURR The style of X11 cross-built, set to either ``Xorg'' or 389 ``XFree86''. 390 391 _D_e_f_a_u_l_t: ``Xorg'' on amd64, i386, macppc, shark and sparc64 392 platforms, ``XFree86'' on everything else. 393 394 ""mmaakkee"" vvaarriiaabblleess ffoorr ffuullll bbuuiillddss 395 These variables only affect the top level ``Makefile'' and do not affect 396 manually building subtrees of the NetBSD source code. 397 398 IINNSSTTAALLLLWWOORRLLDDDDIIRR Location for the ``make installworld'' target to install 399 to. If specified, must be an absolute path. 400 401 _D_e_f_a_u_l_t: ``/'' 402 403 MMKKOOBBJJDDIIRRSS Can be set to ``yes'' or ``no''. Indicates whether 404 object directories will be created automatically (via a 405 ``make obj'' pass) at the start of a build. 406 407 _D_e_f_a_u_l_t: ``no'' 408 409 If using bbuuiilldd..sshh, the default is ``yes''. This may be 410 set back to ``no'' by giving bbuuiilldd..sshh the --oo option. 411 412 MMKKUUPPDDAATTEE Can be set to ``yes'' or ``no''. If set, then in 413 addition to the effects described for MMKKUUPPDDAATTEE==yyeess 414 above, this implies the effects of NNOOCCLLEEAANNDDIIRR (i.e., 415 ``make cleandir'' is avoided). 416 417 _D_e_f_a_u_l_t: ``no'' 418 419 If using bbuuiilldd..sshh, this may be set by giving the --uu 420 option. 421 422 NNBBUUIILLDDJJOOBBSS Now obsolete. Use the make(1) option --jj, instead. See 423 below. 424 425 _D_e_f_a_u_l_t: Unset. 426 427 NNOOCCLLEEAANNDDIIRR If set, avoids the ``make cleandir'' phase of a full 428 build. This has the effect of allowing only changed 429 files in a source tree to be recompiled. This can speed 430 up builds when updating only a few files in the tree. 431 432 _D_e_f_a_u_l_t: Unset. 433 434 See also MMKKUUPPDDAATTEE. 435 436 NNOODDIISSTTRRIIBBDDIIRRSS If set, avoids the ``make distrib-dirs'' phase of a full 437 build. This skips running mtree(8) on DDEESSTTDDIIRR, useful 438 on systems where building as an unprivileged user, or 439 where it is known that the system-wide mtree files have 440 not changed. 441 442 _D_e_f_a_u_l_t: Unset. 443 444 NNOOIINNCCLLUUDDEESS If set, avoids the ``make includes'' phase of a full 445 build. This has the effect of preventing make(1) from 446 thinking that some programs are out-of-date simply 447 because the system include files have changed. However, 448 this option should not be used when updating the entire 449 NetBSD source tree arbitrarily; it is suggested to use 450 MMKKUUPPDDAATTEE==yyeess instead in that case. 451 452 _D_e_f_a_u_l_t: Unset. 453 454 RREELLEEAASSEEDDIIRR If set, specifies the directory to which a release(7) 455 layout will be written at the end of a ``make release''. 456 If specified, must be an absolute path. 457 458 _D_e_f_a_u_l_t: Unset. 459 460 _N_o_t_e: bbuuiilldd..sshh will provide a default of _r_e_l_e_a_s_e_d_i_r (in 461 the top-level ..OOBBJJDDIIRR) unless run in `expert' mode. 462 463BBUUIILLDDIINNGG 464 ""mmaakkee"" ccoommmmaanndd lliinnee ooppttiioonnss 465 This is not a summary of all the options available to make(1); only the 466 options used most frequently with NetBSD builds are listed here. 467 468 --jj _n_j_o_b Run up to _n_j_o_b make(1) subjobs in parallel. Makefiles should 469 use .WAIT or have explicit dependencies as necessary to 470 enforce build ordering. 471 472 --mm _d_i_r Specify the default directory for searching for system 473 Makefile segments, mainly the <bsd.*.mk> files. When building 474 any full NetBSD source tree, this should be set to the 475 ``share/mk'' directory in the source tree. This is set 476 automatically when building from the top level, or when using 477 bbuuiilldd..sshh. 478 479 --nn Display the commands that would have been executed, but do not 480 actually execute them. This will still cause recursion to 481 take place. 482 483 --VV _v_a_r Print make(1)'s idea of the value of _v_a_r. Does not build any 484 targets. 485 486 _v_a_r_=_v_a_l_u_e Set the variable _v_a_r to _v_a_l_u_e, overriding any setting 487 specified by the process environment, the MMAAKKEECCOONNFF 488 configuration file, or the system Makefile segments. 489 490 ""mmaakkee"" ttaarrggeettss 491 These default targets may be built by running make(1) in any subtree of 492 the NetBSD source code. It is recommended that none of these be used 493 from the top level Makefile; as a specific exception, ``make obj'' and 494 ``make cleandir'' are useful in that context. 495 496 aallll Build programs, libraries, and preformatted documentation. 497 498 cclleeaann Remove program and library object code files. 499 500 cclleeaannddiirr Same as cclleeaann, but also remove preformatted documentation, 501 dependency files generated by ``make depend'', and any other 502 files known to be created at build time. 503 504 ddeeppeenndd Create dependency files (..ddeeppeenndd) containing more detailed 505 information about the dependencies of source code on header 506 files. Allows programs to be recompiled automatically when a 507 dependency changes. 508 509 ddeeppeennddaallll Does a ``make depend'' immediately followed by a ``make all''. 510 This improves cache locality of the build since both passes 511 read the source files in their entirety. 512 513 ddiissttcclleeaann Synonym for cclleeaannddiirr. 514 515 iinncclluuddeess Build and install system header files. Typically needed 516 before any system libraries or programs can be built. 517 518 iinnssttaallll Install programs, libraries, and documentation into DDEESSTTDDIIRR. 519 Few files will be installed to DDEESSTTDDIIRR_/_d_e_v, DDEESSTTDDIIRR_/_e_t_c, 520 DDEESSTTDDIIRR_/_r_o_o_t or DDEESSTTDDIIRR_/_v_a_r in order to prevent user supplied 521 configuration data from being overwritten. 522 523 lliinntt Run lint(1) against the C source code, where appropriate, and 524 generate system-installed lint libraries. 525 526 oobbjj Create object directories to be used for built files, instead 527 of building directly in the source tree. 528 529 ttaaggss Create ctags(1) searchable function lists usable by the ex(1) 530 and vi(1) text editors. 531 532 ""mmaakkee"" ttaarrggeettss ffoorr tthhee ttoopp lleevveell 533 Additional make(1) targets are usable specifically from the top source 534 level to facilitate building the entire NetBSD source tree. 535 536 bbuuiilldd Build the entire NetBSD system (except the kernel). This 537 orders portions of the source tree such that prerequisites 538 will be built in the proper order. 539 540 ddiissttrriibbuuttiioonn Do a ``make build'', and then install a full distribution 541 (which does not include a kernel) into DDEESSTTDDIIRR, including 542 files in DDEESSTTDDIIRR_/_d_e_v, DDEESSTTDDIIRR_/_e_t_c, DDEESSTTDDIIRR_/_r_o_o_t and 543 DDEESSTTDDIIRR_/_v_a_r. 544 545 bbuuiillddwwoorrlldd As per ``make distribution'', except that it ensures that 546 DDEESSTTDDIIRR is not the root directory. 547 548 iinnssttaallllwwoorrlldd Install the distribution from DDEESSTTDDIIRR to IINNSSTTAALLLLWWOORRLLDDDDIIRR, 549 which defaults to the root directory. Ensures that 550 IINNSSTTAALLLLWWOORRLLDDDDIIRR is not the root directory if cross 551 compiling. 552 553 The IINNSSTTAALLLLSSEETTSS environment variable may be set to a space- 554 separated list of distribution sets to be installed. By 555 default, all sets except ``etc'' and ``xetc'' are 556 installed, so most files in IINNSSTTAALLLLWWOORRLLDDDDIIRR_/_e_t_c will not be 557 installed or modified. 558 559 _N_o_t_e: Before performing this operation with 560 IINNSSTTAALLLLWWOORRLLDDDDIIRR=_/, it is highly recommended that you 561 upgrade your kernel and reboot. After performing this 562 operation, it is recommended that you use etcupdate(8) to 563 update files in IINNSSTTAALLLLWWOORRLLDDDDIIRR_/_e_t_c and that you use 564 postinstall(8) to check for inconsistencies (and possibly 565 to fix them). 566 567 sseettss Create distribution sets from DDEESSTTDDIIRR into 568 RREELLEEAASSEEDDIIRR//RREELLEEAASSEEMMAACCHHIINNEEDDIIRR_/_b_i_n_a_r_y_/_s_e_t_s. Should be run 569 after ``make distribution'', as ``make build'' alone does 570 not install all of the required files. 571 572 ssoouurrcceesseettss Create source sets of the source tree into 573 RREELLEEAASSEEDDIIRR_/_s_o_u_r_c_e_/_s_e_t_s. 574 575 ssyyssppkkggss Create syspkgs from DDEESSTTDDIIRR into 576 RREELLEEAASSEEDDIIRR//RREELLEEAASSEEMMAACCHHIINNEEDDIIRR_/_b_i_n_a_r_y_/_s_y_s_p_k_g_s. Should be run 577 after ``make distribution'', as ``make build'' alone does 578 not install all of the required files. 579 580 rreelleeaassee Do a ``make distribution'', build kernels, distribution 581 media, and install sets (this as per ``make sets''), and 582 then package the system into a standard release layout as 583 described by release(7). This requires that RREELLEEAASSEEDDIIRR be 584 set (see above). 585 586 iissoo--iimmaaggee Create a NetBSD installation CD-ROM image in the 587 RREELLEEAASSEEDDIIRR_/_i_s_o directory. The CD-ROM file system will have 588 a layout as described in release(7). 589 590 For most machine types, the CD-ROM will be bootable, and 591 will automatically run the sysinst(8) menu-based 592 installation program, which can be used to install or 593 upgrade a NetBSD system. Bootable CD-ROMs also contain 594 tools that may be useful in repairing a damaged NetBSD 595 installation. 596 597 Before ``make iso-image'' is attempted, RELEASEDIR must be 598 populated by ``make release'' or equivalent. 599 600 Note that other, smaller, CD-ROM images may be created in 601 the RREELLEEAASSEEDDIIRR//RREELLEEAASSEEMMAACCHHIINNEEDDIIRR_/_i_n_s_t_a_l_l_a_t_i_o_n_/_c_d_r_o_m 602 directory by ``make release''. These smaller images 603 usually contain the same tools as the larger images in 604 RREELLEEAASSEEDDIIRR_/_i_s_o, but do not contain additional content such 605 as the distribution sets. 606 607 Note that the mac68k port still uses an older method of 608 creating CD-ROM images. This requires the mkisofs(1) 609 utility, which is not part of NetBSD, but which can be 610 installed from _p_k_g_s_r_c_/_s_y_s_u_t_i_l_s_/_c_d_r_t_o_o_l_s. 611 612 iissoo--iimmaaggee--ssoouurrccee 613 Create a NetBSD installation CD-ROM image in the 614 RREELLEEAASSEEDDIIRR_/_i_s_o directory. The CD-ROM file system will have 615 a layout as described in release(7). It will have top 616 level directories for the machine type and source. 617 618 For most machine types, the CD-ROM will be bootable, and 619 will automatically run the sysinst(8) menu-based 620 installation program, which can be used to install or 621 upgrade a NetBSD system. Bootable CD-ROMs also contain 622 tools that may be useful in repairing a damaged NetBSD 623 installation. 624 625 Before ``make iso-image-source'' is attempted, RELEASEDIR 626 must be populated by ``make sourcesets release'' or 627 equivalent. 628 629 Note that other, smaller, CD-ROM images may be created in 630 the RREELLEEAASSEEDDIIRR//RREELLEEAASSEEMMAACCHHIINNEEDDIIRR_/_i_n_s_t_a_l_l_a_t_i_o_n_/_c_d_r_o_m 631 directory by ``make release''. These smaller images 632 usually contain the same tools as the larger images in 633 RREELLEEAASSEEDDIIRR_/_i_s_o, but do not contain additional content such 634 as the distribution sets. 635 636 Note that the mac68k port still uses an older method of 637 creating CD-ROM images. This requires the mkisofs(1) 638 utility, which is not part of NetBSD, but which can be 639 installed from _p_k_g_s_r_c_/_s_y_s_u_t_i_l_s_/_c_d_r_t_o_o_l_s. 640 641 iinnssttaallll--iimmaaggee 642 Create a bootable NetBSD installation disk image in the 643 RREELLEEAASSEEDDIIRR//RREELLEEAASSEEMMAACCHHIINNEEDDIIRR_/_i_n_s_t_a_l_l_a_t_i_o_n_/_i_n_s_t_a_l_l_i_m_a_g_e 644 directory. The installation disk image is suitable for 645 copying to bootable USB flash memory sticks, etc., for 646 machines which are able to boot from such devices. The 647 file system in the bootable disk image will have a layout 648 as described in release(7). 649 650 The installation image is bootable, and will automatically 651 run the sysinst(8) menu-based installation program, which 652 can be used to install or upgrade a NetBSD system. The 653 image also contains tools that may be useful in repairing a 654 damaged NetBSD installation. 655 656 Before ``make install-image'' is attempted, RREELLEEAASSEEDDIIRR must 657 be populated by ``make release'' or equivalent. The build 658 must have been performed with MMKKUUNNPPRRIIVVEEDD==yyeess because ``make 659 install-image'' relies on information in DDEESSTTDDIIRR_/_M_E_T_A_L_O_G. 660 661 live-image Create NetBSD live images in the 662 RREELLEEAASSEEDDIIRR//RREELLEEAASSEEMMAACCHHIINNEEDDIIRR_/_i_n_s_t_a_l_l_a_t_i_o_n_/_l_i_v_e_i_m_a_g_e 663 directory. The live image contains all necessary files to 664 boot NetBSD up to multi-user mode, including all files 665 which should be extracted during installation, NetBSD 666 disklabel, bootloaders, etc. 667 668 The live image is suitable for use as a disk image in 669 virtual machine environments such as QEMU, and also useful 670 to boot NetBSD from a USB flash memory stick on a real 671 machine, without the need for installation. 672 673 Before ``make live-image'' is attempted, RELEASEDIR must be 674 populated by ``make release'' or equivalent. The build 675 must have been performed with MMKKUUNNPPRRIIVVEEDD==yyeess because ``make 676 install-image'' relies on information in DDEESSTTDDIIRR_/_M_E_T_A_L_O_G. 677 678 rreeggrreessssiioonn--tteessttss 679 Can only be run after building the regression tests in the 680 directory ``regress''. Runs those compiled regression 681 tests on the local host. Note that most tests are now 682 managed instead using atf(7); this target should probably 683 run those as well but currently does not. 684 685 TThhee ""bbuuiilldd..sshh"" ssccrriipptt 686 This script file is a shell script designed to build the entire NetBSD 687 system on any host with a suitable modern shell and some common 688 utilities. The required shell features are described under the HHOOSSTT__SSHH 689 variable. 690 691 If a host system's default shell does support the required features, then 692 we suggest that you explicitly specify a suitable shell using a command 693 like 694 695 /path/to/suitable/shell build.sh [_o_p_t_i_o_n_s] 696 697 The above command will usually enable bbuuiilldd..sshh to automatically set 698 HHOOSSTT__SSHH==_/_p_a_t_h_/_t_o_/_s_u_i_t_a_b_l_e_/_s_h_e_l_l, but if that fails, then the following 699 set of commands may be used instead: 700 701 HOST_SH=_/_p_a_t_h_/_t_o_/_s_u_i_t_a_b_l_e_/_s_h_e_l_l 702 export HOST_SH 703 ${HOST_SH} build.sh [_o_p_t_i_o_n_s] 704 705 If bbuuiilldd..sshh detects that it is being executed under an unsuitable shell, 706 it attempts to exec a suitable shell instead, or prints an error message. 707 If HHOOSSTT__SSHH is not set explicitly, then bbuuiilldd..sshh sets a default using 708 heuristics dependent on the host platform, or from the shell under which 709 bbuuiilldd..sshh is executed (if that can be determined), or using the first copy 710 of _s_h found in PPAATTHH. 711 712 All cross-compile builds, and most native builds, of the entire system 713 should make use of bbuuiilldd..sshh rather than just running ``make''. This way, 714 the make(1) program will be bootstrapped properly, in case the host 715 system has an older or incompatible ``make'' program. 716 717 When compiling the entire system via bbuuiilldd..sshh, many make(1) variables are 718 set for you in order to help encapsulate the build process. In the list 719 of options below, variables that are automatically set by bbuuiilldd..sshh are 720 noted where applicable. 721 722 The following operations are supported by bbuuiilldd..sshh: 723 724 bbuuiilldd Build the system as per ``make build''. Before the main 725 part of the build commences, this command runs the oobbjj 726 operation (unless the --oo option is given), ``make 727 cleandir'' (unless the --uu option is given), and the ttoooollss 728 operation. 729 730 ddiissttrriibbuuttiioonn Build a full distribution as per ``make distribution''. 731 This command first runs the bbuuiilldd operation. 732 733 rreelleeaassee Build a full release as per ``make release''. This command 734 first runs the ddiissttrriibbuuttiioonn operation. 735 736 mmaakkeewwrraappppeerr Create the nnbbmmaakkee--MMAACCHHIINNEE wrapper. This operation is 737 automatically performed for any of the other operations. 738 739 cclleeaannddiirr Perform ``make cleandir''. 740 741 oobbjj Perform ``make obj''. 742 743 ttoooollss Build and install the host tools from _s_r_c_/_t_o_o_l_s. This 744 command will first run ``make obj'' and ``make cleandir'' 745 in the _t_o_o_l_s subdirectory unless the --oo or --uu options 746 (respectively) are given. 747 748 iinnssttaallll=_i_d_i_r Install the contents of DDEESSTTDDIIRR to _i_d_i_r, using ``make 749 installworld''. Note that files that are part of the 750 ``etc'' or ``xetc'' sets will not be installed, unless 751 overridden by the INSTALLSETS environment variable. 752 753 kkeerrnneell=_k_c_o_n_f Build a new kernel. The _k_c_o_n_f argument is the name of a 754 configuration file suitable for use by config(1). If _k_c_o_n_f 755 does not contain any `/' characters, the configuration file 756 is expected to be found in the KKEERRNNCCOONNFFDDIIRR directory, which 757 is typically ssyyss//aarrcchh//MMAACCHHIINNEE//ccoonnff. The new kernel will be 758 built in a subdirectory of KKEERRNNOOBBJJDDIIRR, which is typically 759 ssyyss//aarrcchh//MMAACCHHIINNEE//ccoommppiillee or an associated object directory. 760 761 This command does _n_o_t imply the ttoooollss command; run the 762 ttoooollss command first unless it is _c_e_r_t_a_i_n that the tools 763 already exist and are up to date. 764 765 This command will run ``make cleandir'' on the kernel in 766 question first unless the --uu option is given. 767 768 mmoodduulleess This command will build kernel modules and install them 769 into DDEESSTTDDIIRR. 770 771 rreelleeaasseekkeerrnneell=_k_c_o_n_f 772 Install a gzip(1)ed copy of the kernel previously built by 773 kkeerrnneell=_k_c_o_n_f into 774 RREELLEEAASSEEDDIIRR//RREELLEEAASSEEMMAACCHHIINNEEDDIIRR_/_b_i_n_a_r_y_/_k_e_r_n_e_l, usually as 775 _n_e_t_b_s_d_-_k_c_o_n_f_._g_z, although the ``_n_e_t_b_s_d'' prefix is 776 determined from the ``ccoonnffiigg'' directives in _k_c_o_n_f. 777 778 sseettss Perform ``make sets''. 779 780 ssoouurrcceesseettss Perform ``make sourcesets''. 781 782 ssyyssppkkggss Perform ``make syspkgs''. 783 784 iissoo--iimmaaggee Perform ``make iso-image''. 785 786 iissoo--iimmaaggee--ssoouurrccee 787 Perform ``make iso-image-source''. 788 789 iinnssttaallll--iimmaaggee 790 Perform ``make install-image''. 791 792 lliivvee--iimmaaggee Perform ``make live-image''. 793 794 The following command line options alter the behaviour of the bbuuiilldd..sshh 795 operations described above: 796 797 --aa _a_r_c_h Set the value of MMAACCHHIINNEE__AARRCCHH to _a_r_c_h. 798 799 --BB _b_u_i_l_d_i_d 800 Set the value of BBUUIILLDDIIDD to _b_u_i_l_d_i_d. This will also append the 801 build identifier to the name of the ``make'' wrapper script so 802 that the resulting name is of the form 803 ``nnbbmmaakkee--MMAACCHHIINNEE--BBUUIILLDDIIDD''. 804 805 --CC _c_d_e_x_t_r_a_s 806 Append _c_d_e_x_t_r_a_s to the CCDDEEXXTTRRAA variable, which is a space- 807 separated list of files or directories that will be added to 808 the CD-ROM image that may be create by the ``iso-image'' or 809 ``iso-image-source'' operations. Files will be added to the 810 root of the CD-ROM image, whereas directories will be copied 811 recursively. If relative paths are specified, they will be 812 converted to absolute paths before being used. Multiple paths 813 may be specified via multiple --CC options, or via a single 814 option whose argument contains multiple space-separated paths. 815 816 --DD _d_e_s_t Set the value of DDEESSTTDDIIRR to _d_e_s_t. If a relative path is 817 specified, it will be converted to an absolute path before 818 being used. 819 820 --EE Set `expert' mode. This overrides various sanity checks, and 821 allows: DDEESSTTDDIIRR does not have to be set to a non-root path for 822 builds, and MMKKUUNNPPRRIIVVEEDD==yyeess does not have to be set when 823 building as a non-root user. 824 825 _N_o_t_e: It is highly recommended that you know what you are doing 826 when you use this option. 827 828 --hh Print a help message. 829 830 --jj _n_j_o_b Run up to _n_j_o_b make(1) subjobs in parallel; passed through to 831 make(1). If you see failures for reasons other than running 832 out of memory while using bbuuiilldd..sshh with --jj, please save 833 complete build logs so the failures can be analyzed. 834 835 To achieve the fastest builds, --jj values between (1 + the 836 number of CPUs) and (2 * the number of CPUs) are recommended. 837 Use lower values on machines with limited memory or I/O 838 bandwidth. 839 840 --MM _o_b_j Set MMAAKKEEOOBBJJDDIIRRPPRREEFFIIXX to _o_b_j. Unsets MMAAKKEEOOBBJJDDIIRR. See ``--OO 841 --oobbjj'' for more information. 842 843 For instance, if the source directory is _/_u_s_r_/_s_r_c, a setting of 844 ``--MM _/_u_s_r_/_o_b_j'' will place build-time files under 845 _/_u_s_r_/_o_b_j_/_u_s_r_/_s_r_c_/_b_i_n, _/_u_s_r_/_o_b_j_/_u_s_r_/_s_r_c_/_l_i_b, 846 _/_u_s_r_/_o_b_j_/_u_s_r_/_s_r_c_/_u_s_r_._b_i_n, and so forth. 847 848 If a relative path is specified, it will be converted to an 849 absolute path before being used. bbuuiilldd..sshh imposes the 850 restriction that the argument to the --MM option must not begin 851 with a ``$'' (dollar sign) character; otherwise it would be too 852 difficult to determine whether the value is an absolute or a 853 relative path. If the directory does not already exist, 854 bbuuiilldd..sshh will create it. 855 856 --mm _m_a_c_h Set the value of MMAACCHHIINNEE to _m_a_c_h, except in some special cases 857 listed below. This will also override any value of 858 MMAACCHHIINNEE__AARRCCHH in the process environment with a value deduced 859 from _m_a_c_h, unless --aa is specified. All cross builds require 860 --mm, but if unset on a NetBSD host, the host's value of MACHINE 861 will be detected and used automatically. 862 863 Some machines support multiple values for MMAACCHHIINNEE__AARRCCHH. The 864 following special cases for the _m_a_c_h argument are defined to 865 set the listed values of MMAACCHHIINNEE and MMAACCHHIINNEE__AARRCCHH: 866 867 mmaacchh MMAACCHHIINNEE MMAACCHHIINNEE__AARRCCHH 868 evbarm evbarm (not set) 869 evbarm-eb evbarm armeb 870 evbarm-el evbarm arm 871 evbmips evbmips (not set) 872 evbmips-eb evbmips mipseb 873 evbmips-el evbmips mipsel 874 evbsh3 evbsh3 (not set) 875 evbsh3-eb evbsh3 sh3eb 876 evbsh3-el evbsh3 sh3el 877 sbmips sbmips (not set) 878 sbmips-eb sbmips mipseb 879 sbmips-el sbmips mipsel 880 881 --NN _n_o_i_s_e_l_e_v_e_l 882 Set the ``noisyness'' level of the build, by setting 883 MMAAKKEEVVEERRBBOOSSEE to _n_o_i_s_e_l_e_v_e_l. 884 885 --nn Show the commands that would be executed by bbuuiilldd..sshh, but do 886 not make any changes. This is similar in concept to ``make 887 -n''. 888 889 --OO _o_b_j Create an appropriate transform macro for MMAAKKEEOOBBJJDDIIRR that will 890 place the built object files under _o_b_j. Unsets 891 MMAAKKEEOOBBJJDDIIRRPPRREEFFIIXX. 892 893 For instance, a setting of ``--OO _/_u_s_r_/_o_b_j'' will place build- 894 time files under _/_u_s_r_/_o_b_j_/_b_i_n, _/_u_s_r_/_o_b_j_/_l_i_b, _/_u_s_r_/_o_b_j_/_u_s_r_._b_i_n, 895 and so forth. 896 897 If a relative path is specified, it will be converted to an 898 absolute path before being used. bbuuiilldd..sshh imposes the 899 restriction that the argument to the --OO option must not contain 900 a ``$'' (dollar sign) character. If the directory does not 901 already exist, bbuuiilldd..sshh will create it. 902 903 In normal use, exactly one of the --MM or --OO options should be 904 specified. If neither --MM nor --OO is specified, then a default 905 object directory will be chosen according to rules in 906 <bsd.obj.mk>. Relying on this default is not recommended 907 because it is determined by complex rules that are influenced 908 by the values of several variables and by the location of the 909 source directory. 910 911 --oo Set the value of MMKKOOBBJJDDIIRRSS to ``no''. Otherwise, it will be 912 automatically set to ``yes''. This default is opposite to the 913 behaviour when not using bbuuiilldd..sshh. 914 915 --RR _r_e_l Set the value of RREELLEEAASSEEDDIIRR to _r_e_l. If a relative path is 916 specified, it will be converted to an absolute path before 917 being used. 918 919 --rr Remove the contents of DDEESSTTDDIIRR and TTOOOOLLDDIIRR before building 920 (provides a clean starting point). This will skip deleting 921 DDEESSTTDDIIRR if building on a native system to the root directory. 922 923 --SS _s_e_e_d Change the value of BBUUIILLDDSSEEEEDD to _s_e_e_d. This should rarely be 924 necessary. 925 926 --TT _t_o_o_l_s Set the value of TTOOOOLLDDIIRR to _t_o_o_l_s. If a relative path is 927 specified, it will be converted to an absolute path before 928 being used. If set, the bootstrap ``make'' will only be 929 rebuilt if the source files for make(1) have changed. 930 931 --UU Set MMKKUUNNPPRRIIVVEEDD==yyeess. 932 933 --uu Set MMKKUUPPDDAATTEE==yyeess. 934 935 --VV _v_a_r=[_v_a_l_u_e] 936 Set the environment variable _v_a_r to an optional _v_a_l_u_e. This is 937 propagated to the nnbbmmaakkee wrapper. 938 939 --ww _w_r_a_p_p_e_r 940 Create the nnbbmmaakkee wrapper script (see below) in a custom 941 location, specified by _w_r_a_p_p_e_r. This allows, for instance, to 942 place the wrapper in PPAATTHH automatically. Note that _w_r_a_p_p_e_r is 943 the full name of the file, not just a directory name.
