1# $NetBSD: bsd.README,v 1.428 2021/12/23 20:08:07 christos Exp $ 2# @(#)bsd.README 8.2 (Berkeley) 4/2/94 3 4This is the README file for the make "include" files for the NetBSD 5source tree. The files are installed in /usr/share/mk, and are, 6by convention, named with the suffix ".mk". 7 8Note, this file is not intended to replace reading through the .mk 9files for anything tricky. 10 11=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= 12 13RANDOM THINGS WORTH KNOWING: 14 15The files are simply C-style #include files, and pretty much behave like 16you'd expect. The syntax is slightly different in that a single '.' is 17used instead of the hash mark, i.e. ".include <bsd.prog.mk>". 18 19One difference that will save you lots of debugging time is that inclusion 20of the file is normally done at the *end* of the Makefile. The reason for 21this is because .mk files often modify variables and behavior based on the 22values of variables set in the Makefile. To make this work, remember that 23the FIRST target found is the target that is used, i.e. if the Makefile has: 24 25 a: 26 echo a 27 a: 28 echo a number two 29 30the command "make a" will echo "a". To make things confusing, the SECOND 31variable assignment is the overriding one, i.e. if the Makefile has: 32 33 a= foo 34 a= bar 35 36 b: 37 echo ${a} 38 39the command "make b" will echo "bar". This is for compatibility with the 40way the V7 make behaved. 41 42It's fairly difficult to make the BSD .mk files work when you're building 43multiple programs in a single directory. It's a lot easier to split up the 44programs than to deal with the problem. Most of the agony comes from making 45the "obj" directory stuff work right, not because we switched to a new version 46of make. So, don't get mad at us, figure out a better way to handle multiple 47architectures so we can quit using the symbolic link stuff. (Imake doesn't 48count.) 49 50The file .depend in the source directory is expected to contain dependencies 51for the source files. This file is read automatically by make after reading 52the Makefile. 53 54The variable DESTDIR works as before. It's not set anywhere but will change 55the tree where the file gets installed. 56 57The profiled libraries are no longer built in a different directory than 58the regular libraries. A new suffix, ".po", is used to denote a profiled 59object, and ".pico" denotes a shared (position-independent) object. 60 61There are various make variables used during the build. 62 63Many variables support a (case sensitive) value of "no" or "yes", 64and are tested with ${VAR} == "no" and ${VAR} != "no" . 65 66 67The basic rule for the variable naming scheme is as follows: 68 69HOST_xxx A command that runs on the host machine regardless of 70 whether or not the system is being cross compiled, or 71 flags for such a command. 72 73MKxxx Can be set to "no" to disable functionality, or 74 "yes" to enable it. 75 Usually defaults to "yes", although some variables 76 default to "no". 77 Due to make(1) implementation issues, if a temporary 78 command-line override of a mk.conf(5) or <bsd.own.mk> 79 setting is required whilst still honoring a particular 80 Makefile's setting of MKxxx, use 81 env MKxxx=value make 82 instead of 83 make MKxxx=value 84 85NOxxx If defined, disables a feature. 86 Not intended for users. 87 This is to allow Makefiles to disable functionality 88 that they don't support (such as missing man pages). 89 NOxxx variables must be defined before <bsd.own.mk> 90 is included. 91 92TOOL_xxx A tool that is provided as part of the USETOOLS 93 framework. When not using the USETOOLS framework, 94 TOOL_xxx variables should refer to tools that are 95 already installed on the host system. 96 97The following variables control how things are made/installed that 98are not set by default. These should not be set by Makefiles; they're for 99the user to define in MAKECONF (see <bsd.own.mk>, below, or mk.conf(5)) 100or on the make(1) command line: 101 102BUILD If defined, 'make install' checks that the targets in the 103 source directories are up-to-date and remakes them if they 104 are out of date, instead of blindly trying to install 105 out of date or non-existent targets. 106 107MAKEVERBOSE Control how "verbose" the standard make(1) rules are. 108 Default: 2 109 Supported values: 110 0 Minimal output ("quiet") 111 1 Describe what is occurring 112 2 Describe what is occurring and echo the actual command 113 3 Ignore the effect of the "@" prefix in make commands 114 4 Trace shell commands using the shell's -x flag 115 116MKARGON2 If "no", don't build support for Argon2 into libcrypt. 117 Default: yes 118 119MKATF If "no", don't build the Automated Testing Framework (ATF), 120 which includes the libatf-c, libatf-c++ and libatf-sh libraries 121 and the various command line tools. Also, because the build of 122 the libraries is disabled, don't build the NetBSD test suite 123 either. 124 Default: yes 125 126MKBFD Obsolete, use MKBINUTILS 127 128MKBINUTILS If "no", don't build binutils (gas, ld, etc and libbfd, 129 libopcodes) 130 Default: yes 131 132MKBSDTAR If "yes", use the libarchive based cpio and tar instead of 133 the pax frontends. 134 Default: yes 135 136MKCATPAGES If "no", don't build or install the catman pages. 137 Default: no 138 139MKCOMPAT If "no", don't build or install the src/compat. 140 Default: yes on amd64, mips64 and sparc64, no elsewhere. 141 142MKCOMPATTESTS If "yes", build and install the NetBSD test suite when 143 building and installing src/compat. 144 Default: no 145 146MKCOMPATX11 If "yes", build and install the X11 libraries when 147 building and installing src/compat. 148 Default: no 149 150MKCOMPATMODULES If "no", don't build compat modules (xen, etc.) 151 Default: yes 152 153MKCOMPLEX If "no", don't build libm support for <complex.h> 154 Default: yes 155 156MKCTF If "no", do not build and install CTF tools, and also 157 don't generate and manipulate CTF data of ELF binaries 158 during build. 159 Default: no 160 161NETBSD_OFFICIAL_RELEASE 162 If defined and set to "yes", the build targets an official 163 NetBSD release which is going to be available from 164 ftp.NetBSD.org / cdn.NetBSD.org. This modifies a few 165 default paths in the installer and also creates different 166 links in the install documentation. 167 The auto-build cluster uses this variable to distinguish 168 "daily" builds from real releases. 169 Default: undefined (no) 170 171NOCTF Don't generate and manipulate CTF data of ELF binaries 172 during build. It is set internally for standalone programs. 173 174MKCVS If "no", don't build or install cvs(1). 175 Default: yes 176 177MKDEBUG If "no", don't build and install separate debugging symbols 178 into /usr/libdata/debug. 179 Default: no 180 181NODEBUG Don't compile with debugging symbols during build. 182 It is set internally for standalone programs. 183 184MKDEBUGLIB Build *_g.a debugging libraries, which are compiled 185 with -DDEBUG. 186 Default: no 187 188MKDEBUGKERNEL If "yes", force building of kernel symbol info and creation 189 of netbsd.gdb in all kernel builds, independently of the 190 settings for "makeoptions DEBUG" in the kernel config file. 191 The .gdb kernels will be included with the kernel sets. 192 Default: no 193 194MKDEBUGTOOLS If "yes" build the tools with debugging symbols. 195 Default: no 196 197MKDEPINCLUDES If "yes" issue .include statements in the .depend file 198 instead of inlining the contents of the .d files. Useful 199 when stale dependencies are present, to list the exact 200 files that need refreshing. It is off by default because 201 it is possibly slower. 202 Default "no" 203 204MKDOC If "no", don't build or install the documentation. 205 Default: yes 206 207MKDTRACE If "no", do not build and install the kernel modules, 208 utilities and libraries used to implement the dtrace(1) 209 facility. 210 Default: no 211 212MKDTB If "no", disables building of devicetree blobs. 213 Default: yes on aarch64 and armv7, no elsewhere. 214 215MKDYNAMICROOT If "no", build programs in /bin and /sbin statically, 216 don't install certain libraries in /lib, and don't 217 install the shared linker into /libexec. 218 Default: yes 219 220MKEXTSRC If not "no", 'make build' also descends into either src/extsrc 221 to cross-build programs and libraries externally added by 222 users, and automatically enables creation of those sets. 223 Default: no 224 225MKFIRMWARE If not "no", install the /libdata/firmware directory, 226 which is necessary for several drivers: athn(4), bwfm(4), 227 ipw(4), iwi(4), iwm(4), iwn(4), otus(4), rtwn(4), urtwn(4), 228 wpi(4), ral(4), rum(4), run(4), zyd(4), bcm43xx(4), and 229 the Tegra 124 SoC. 230 Default: yes on amd64, cobalt, evbarm evbmips, evbppc, hpcarm, 231 hppa, i386, mac68k, macppc, sandpoint, and sparc64, no elsewhere. 232 233MKGCC If "no", don't build gcc(1) or any of the GCC-related 234 libraries (libgcc, libobjc, libstdc++). 235 Default: yes 236 237MKGCCCMDS If "no", don't build gcc(1), but do build the GCC-related 238 libraries (libgcc, libobjc, libstdc++). 239 Default: yes 240 241MKGDB If "no", don't build gdb(1). 242 Default: yes 243 244MKGROFFHTMLDOC If "no", avoid trying to use groff to generate html for 245 miscellaneous articles, as this seems to sometimes want 246 to run software not in base. Does not affect html man 247 pages. 248 Default: no 249 250MKHESIOD If "no", disables building of Hesiod infrastructure 251 (libraries and support programs). 252 Default: yes 253 254MKHOSTOBJ If not "no", for programs intended to be run on the compile 255 host, the name, release, and architecture of the host 256 operating system will be suffixed to the name of the object 257 directory created by "make obj". 258 Default: no 259 260MKHTML If "no", don't build or install the HTML man pages. 261 Default: yes 262 263MKIEEEFP If "no", don't add code for IEEE754/IEC60559 conformance. 264 Has no effect on most platforms. 265 Default: yes 266 267MKSTRIPIDENT Strip the RCS IDs from program binaries and shared libraries. 268 Default: no 269 270MKINET6 If "no", disables building of INET6 (IPv6) infrastructure 271 (libraries and support programs). This option must not be 272 set to "no" if MKX11 is not "no". 273 Default: yes 274 275MKINFO If "no", don't build or install Info documentation from 276 Texinfo source files. 277 Default: yes 278 279MKIPFILTER If "no", don't build or install the IP Filter programs and LKM. 280 Default: yes 281 282MKISCSI If "no", don't build or install iSCSI library or applications 283 (depends on libpthread.) 284 Default: yes 285 286MKKERBEROS If "no", disables building of Kerberos v5 287 infrastructure (libraries and support programs). 288 Default: yes 289 290MKKMOD If "no", disables building of kernel modules. 291 Default: yes 292 293MKKYUA If "no", don't build Kyua nor its dependent library Lutok. 294 Note that setting this to "no" does not disable the build of 295 the NetBSD test suite itself; the build of the tests is 296 controlled by the MKATF knob. 297 Default: no (until the import is done and validated) 298 299MKLDAP If "no", disables building of LDAP infrastructure 300 (libraries and support programs). 301 Default: yes 302 303MKLIBCSANITIZER If "yes", use the selected sanitizer inside libc to compile 304 userland programs and libraries as defined in 305 USE_LIBCSANITIZER, which defaults to "undefined". 306 307 The undefined behavior detector is currently the only supported 308 sanitizer in this mode. Its runtime differs from the UBSan 309 available in MKSANITIZER, and it is reimplemented from scratch 310 as micro-UBSan in the user mode (uUBSan). Its code is shared 311 with the kernel mode variation (kUBSan). The runtime is 312 stripped down from C++ features, in particular -fsanitize=vptr 313 is not supported and explicitly disabled. The only runtime 314 configuration is restricted to the LIBC_UBSAN environment 315 variable, that is designed to be safe for hardening. 316 317 The USE_LIBCSANITIZER value is passed to the -fsanitize= 318 argument to the compiler in CFLAGS and CXXFLAGS, but not in 319 LDFLAGS, as the runtime part is located inside libc. 320 321 Additional sanitizer arguments can be passed through 322 LIBCSANITIZERFLAGS. 323 Default: no 324 325MKLIBCXX If not "no", build and install libc++. 326 Default: no 327 328MKLIBSTDCXX If not "no", build and install libstdc++. 329 Default: yes 330 331MKLINKLIB If "no", act as "MKLINT=no MKPICINSTALL=no MKPROFILE=no". 332 Also: 333 - don't install the .a libraries 334 - don't install _pic.a libraries on PIC systems 335 - don't build .a libraries on PIC systems 336 - don't install the .so symlink on ELF systems 337 I.e, only install the shared library (and the .so.major 338 symlink on ELF). 339 Default: yes 340 341MKLINT If "no", don't build or install the lint libraries. 342 Default: yes 343 344MKLLVM If "yes", build and install clang as host tool and target 345 compiler. Use as system compiler is enabled with HAVE_LLVM 346 (see below for details). 347 Default: no 348 349MKLLVMRT If "yes", build the LLVM PIC libraries necessary for the 350 various Mesa backend and the native JIT of the target 351 architecture, if supported. (Radeon R300 and newer, 352 LLVMPIPE for most.) 353 Default: no, enabled automatically with X11 on x86 and aarch64. 354 355MKLVM If "no", don't build or install the logical volume manager 356 and device mapper tools and libraries 357 Default: yes 358 359MKMAN If "no", don't build or install the man or catman pages, 360 and also acts as "MKCATPAGES=no MKHTML=no". 361 Default: yes 362 363MKMANDOC If "yes", mandoc is built as tool and used to compile 364 catman or html pages. A directory can be exempted by 365 defining NOMANDOC. Individual man pages are exempted 366 if NOMANDOC.${target} is set to "yes". 367 Default: yes 368 369MKMANZ If not "no", compress manual pages at installation time. 370 Default: no 371 372MKMDNS If "no", disables building of mDNS infrastructure 373 (libraries and support programs). 374 Default: yes 375 376MKNLS If "no", don't build or install the NLS files and locale 377 definition files. 378 Default: yes 379 380MKNOUVEAUFIRMWARE If "yes", install the /libdata/firmware/nouveau directory, 381 which is necessary for the nouveau DRM driver. 382 Default: yes on amd64 and i386, no elsewhere. 383 384MKNPF If "no", don't build or install the NPF and its modules. 385 Default: yes 386 387MKNSD If "no", don't build or install the "nsd" DNS authoritative 388 server. 389 Default: no 390 391MKOBJ If "no", don't enable the rule which creates objdirs, 392 and also acts as "MKOBJDIRS=no". 393 Default: yes 394 395MKOBJDIRS If "no", don't create objdirs during a "make build". 396 Default: no 397 398MKPAM If "no", disables building of PAM authentication 399 infrastructure (libraries and support programs). 400 Default: yes 401 402MKPCC If "no", don't build pcc(1) or any of the PCC-related 403 libraries (libpcc, libpccsoftfloat). 404 Default: no 405 406MKPF If "no", don't build or install the pf programs and LKM. 407 Default: yes 408 409MKPIC If "no", don't build or install shared libraries, and 410 also acts as "MKPICLIB=no" 411 Default: yes (for MACHINE_ARCHs that support it) 412 413MKPICINSTALL If "no", don't install the *_pic.a libraries. 414 Default: yes 415 416MKPICLIB If "no", don't build *_pic.a libraries, and build the 417 shared object libraries from the .a libraries. 418 A symlink is installed in ${DESTDIR}/usr/lib for the 419 _pic.a library pointing to the .a library. 420 Default: yes 421 422MKPIE If "no", create regular executables. Otherwise create 423 PIE (Position Independent Executables). 424 Default: no 425 426NOPIE Don't create PIE (Position Independent Executables) 427 It is set internally for standalone programs. 428 429MKPIGZGZIP If "no", only install pigz as pigz, not gzip. 430 Default: no 431 432MKPOSTFIX If "no", don't build or install postfix(1). 433 Default: yes 434 435MKPROFILE If "no", don't build or install the profiling (*_p.a) libraries. 436 Default: yes 437 438MKRADEONFIRMWARE If "yes", install the /libdata/firmware/radeon directory, 439 which is necessary for the radeon DRM driver. 440 Default: yes on amd64 and i386, no elsewhere. 441 442MKRELRO If "partial", set the non-PLT GOT to read-only. If "full" 443 also force immediate symbol binding. 444 Default: no 445 446NOFULLRELRO Don't compile with immediate symbol binding during build. 447 It is set internally for standalone programs. 448 449MKREPRO If "yes", create reproducible builds. This enables 450 different switches to make two builds from the same source tree 451 result in the same build results. 452 Default: no 453 454MKSANITIZER if "yes", use the selected sanitizer to compile userland 455 programs as defined in USE_SANITIZER, which defaults to 456 "address". A selection of available sanitizers: 457 address: A memory error detector (default) 458 thread: A data race detector 459 memory: An uninitialized memory read detector 460 undefined: An undefined behavior detector 461 leak: A memory leak detector 462 dataflow: A general data flow analysis 463 cfi: A control flow detector 464 safe-stack: Protect against stack-based corruption 465 scudo: The Scudo Hardened allocator 466 It's possible to specify multiple sanitizers within the 467 USE_SANITIZER option (comma separated). The USE_SANITIZER value 468 is passed to the -fsanitize= argument to the compiler. 469 Additional arguments can be passed through SANITIZERFLAGS. 470 The list of supported features and their valid combinations 471 depends on the compiler version and target CPU architecture. 472 Default: no 473 474MKSHARE If "no", act as "MKCATPAGES=no MKDOC=no MKHTML=no MKINFO=no 475 MKMAN=no MKNLS=no". 476 I.e, don't build catman pages, documentation, Info 477 documentation, man pages, NLS files, ... 478 Default: yes 479 480MKSKEY If "no", disables building of S/key authentication 481 infrastructure (libraries and support programs). 482 Default: yes 483 484MKSLJIT If "no", disables building of sljit (stack-less platform 485 independent JIT compiler) private library and tests. 486 Default: yes on amd64, i386 and sparc, no elsewhere. 487 488MKSOFTFLOAT If not "no", build with options to enable the compiler to 489 generate output containing library calls for floating 490 point and possibly soft-float library support. 491 Default: no 492 493MKSTATICLIB If "no", don't build or install the normal static (*.a) 494 libraries. 495 Default: yes 496 497MKSTATICPIE Compile in support for static pie binaries. These binaries 498 use a special support in crt0.o for resolving relative 499 relocations and require linker support. 500 Default: yes on platforms that support it. 501 502MKSTRIPSYM If "yes", strip all local symbols from shared libraries; 503 the affect is equivalent to -x option of ld(1). If "no", 504 strip only temporary local symbols; the affect is equivalent 505 to -X option of ld(1). Keeping non-temporary local symbols 506 such as static function names is useful on using DTrace for 507 userland libraries and getting a backtrace from a rump kernel 508 loading shared libraries. 509 Default: yes 510 511MKTEGRAFIRMWARE If "no", install the /libdata/firmware/nvidia directory, 512 which is necessary for the NVIDIA Tegra XHCI driver. 513 Default: yes on evbarm, no elsewhere. 514 515MKTPM If "no" then don't build the Trusted Platform Module 516 infrastructure. 517 Default: no 518 519MKUNBOUND If not "no", build and install the "unbound" DNS resolver. 520 Default: yes 521 522MKUNPRIVED If not "no", don't set the owner/group/mode when installing 523 files or directories, and keep a metadata log of what 524 the owner/group/mode should be. This allows a 525 non-root "make install". 526 Default: no 527 528MKUPDATE If not "no", 'make install' only installs targets that are 529 more recently modified in the source directories that their 530 installed counterparts. 531 Default: no 532 533MKX11 If not "no", 'make build' also descends into 534 src/external/mit/xorg to cross-build X11 and automatically 535 enables creation of X sets. 536 Default: no 537 538MKX11FONTS If not "no", do not build or install the X fonts. The xfont 539 set is still created but will be empty. 540 Default: yes 541 542MKX11MOTIF: If "yes", build the native X11 libGLw with Motif stubs. If 543 Motif is not installed in the default location /usr/pkg, the 544 location can be specified using the X11MOTIFPATH variable. 545 Default: no 546 547MKYP If "no", disables building of YP (NIS) 548 infrastructure (libraries and support programs). 549 Default: yes 550 551MKZFS If "no", do not build and install utilities and libraries 552 used to manage ZFS file system. Do not build zfs and solaris 553 compatibility kernel modules. Note: ZFS requires 64bit 554 atomic operations. 555 Default: yes on aarch64, amd64 and sparc64, no elsewhere. 556 557MKRUMP If "no", do not build and install rump related headers, 558 libraries, and programs. 559 Default: yes 560 561USE_HESIOD If "no", disables building Hesiod support into 562 various system utilities/libraries that support it. 563 If ${MKHESIOD} is "no", USE_HESIOD will also be 564 forced to "no". 565 566USE_INET6 If "no", disables building INET6 (IPv6) support into 567 various system utilities/libraries that support it. 568 If ${MKINET6} is "no", USE_INET6 will also be 569 forced to "no". 570 571USE_JEMALLOC If "no", disables building the "jemalloc" allocator 572 designed for improved performance with threaded 573 applications. The "phkmalloc" allocator as used up 574 before NetBSD-5.0 will be substituted. 575 576USE_KERBEROS If "no", disables building Kerberos v5 577 support into various system utilities/libraries that 578 support it. If ${MKKERBEROS} is "no", USE_KERBEROS 579 will also be forced to "no". 580 581USE_LDAP If "no", disables building LDAP support into various 582 system utilities/libraries that support it. 583 If ${MKLDAP} is "no", USE_LDAP will also be forced to "no". 584 585USE_PAM If "no", disables building PAM authentication support 586 into various system utilities/libraries that support it. 587 If ${MKPAM} is "no", USE_PAM will also be forced to "no". 588 589USE_SKEY If "no", disables building S/key authentication 590 support into various system utilities/libraries that 591 support it. If ${MKSKEY} is "no", USE_SKEY will 592 also be forced to "no". 593 Default: no 594 595USE_SSP If "no", disables GCC stack protection code, which 596 detects stack overflows and aborts the program. The 597 stack protection code imposes a performance penalty 598 of about 5%. 599 Default: "no", unless "USE_FORT" is set to "yes" 600 601NOSSP Don't compile with stack protector during build. 602 It is set internally for standalone programs. 603 604USE_FORT If "yes" turns on substitute wrappers for commonly used 605 functions that do not do bounds checking regularly, but 606 they could in some cases by using the gcc 607 __builtin_object_size() function to determine the buffer 608 size where it is known and detect buffer overflows. 609 These substitute functions are in /usr/include/ssp. 610 Default: depends on the part of the source tree 611 612NOFORT Don't compile with substitute wrappers during build. 613 It is set internally for standalone programs. 614 615USE_YP If "no", disables building YP (NIS) support into 616 various system utilities/libraries that support it. 617 If ${MKYP} is "no", USE_YP will also be forced to "no". 618 619USE_PIGZGZIP If "no", use the host "gzip" program to compress things. 620 Otherwise, build tools/pigz, set TOOL_GZIP=${TOOL_PIGZ}, 621 and use nbpigz to compress things. 622 Default: "no". 623 624USE_XZ_SETS If "no", use the host "gzip" program to compress sets. 625 Otherwise use xz to compress things. 626 Default: "yes" for architectures with "enough" memory to 627 decompress, "no" for older ones. 628 This is currently incompatible with USE_PIGZGZIP, setting 629 USE_PIGZGZIP=yes sets USE_XZ_SETS=no by default for all 630 architectures. 631 632COPTS.lib<lib> 633OBJCOPTS.lib<lib> 634LDADD.lib<lib> 635CPPFLAGS.lib<lib> 636CXXFLAGS.lib<lib> 637COPTS.<prog> 638OBJCOPTS.<prog> 639LDADD.<prog> 640CPPFLAGS.<prog> 641CXXFLAGS.<prog> These provide a way to specify additions to the associated 642 variables in a way that applies only to a particular library 643 or program. <lib> corresponds to the LIB variable set in 644 the library's makefile. <prog> corresponds to either PROG 645 or PROG_CXX (if set). For example, if COPTS.libcrypto is 646 set to "-g", "-g" will be added to COPTS only when compiling 647 the crypto library. 648 649The active compiler is selected using the following variables: 650AVAILABLE_COMPILER 651 List of available compiler suites. Processed in order 652 for selecting the active compiler for each frontend. 653HAVE_PCC If defined, PCC is present and enabled. 654HAVE_LLVM If defined, LLVM/Clang is present and enabled. 655UNSUPPORTED_COMPILER.xxx 656 If defined, the support for compiler "xxx" is disabled. 657 658For the frontends (CC, CPP, CXX, FC and OBJC) the following variables exist: 659ACTIVE_CC Active compile suite for the CC frontend. 660SUPPORTED_CC Compile suite with support for the CC frontend. 661TOOL_CC.xxx Path to the CC frontend for compiler "xxx" 662 663=-=-=-=-= sys.mk =-=-=-=-= 664 665The include file <sys.mk> has the default rules for all makes, in the BSD 666environment or otherwise. You probably don't want to touch this file. 667 668=-=-=-=-= bsd.own.mk =-=-=-=-= 669 670The include file <bsd.own.mk> contains source tree configuration parameters, 671such as the owners, groups, etc. for both manual pages and binaries, and 672a few global "feature configuration" parameters. 673 674It has no targets. 675 676To get system-specific configuration parameters, <bsd.own.mk> will try to 677include the file specified by the "MAKECONF" variable. If MAKECONF is not 678set, or no such file exists, the system make configuration file, /etc/mk.conf 679is included. These files may define any of the variables described below. 680 681<bsd.own.mk> sets the following variables, if they are not already defined 682(defaults are in brackets): 683 684NETBSDSRCDIR Top of the NetBSD source tree. 685 If _SRC_TOP_ != "", that will be used as the default, 686 otherwise BSDSRCDIR will be used as the default. 687 Various makefiles within the NetBSD source tree will 688 use this to reference the top level of the source tree. 689 690_SRC_TOP_ Top of the system source tree, as determined by <bsd.own.mk> 691 based on the presence of tools/ and build.sh. This variable 692 is "internal" to <bsd.own.mk>, although its value is only 693 determined once and then propagated to all sub-makes. 694 695_NETBSD_VERSION_DEPENDS 696 A list of files which contain information about 697 the version of the NetBSD being built. This is 698 defined only if the current directory appears 699 to be inside a NetBSD source tree. The list of 700 files includes ${NETBSDSRCDIR}/sys/sys/param.h 701 (which contains the kernel version number), 702 ${NETBSDSRCDIR}/sys/conf/newvers.sh and 703 ${NETBSDSRCDIR}/sys/conf/osrelease.sh (which 704 interpret the information in sys/sys/param.h), and 705 ${_SRC_TOP_OBJ_}/params (which is an optional file, 706 created by "make build" in ${_SRC_TOP_}/Makefile, 707 containing all the variables that may influence the 708 build). 709 710 Targets that depend on the NetBSD version, or on 711 variables defined at build time, can declare a 712 dependency on ${_NETBSD_VERSION_DEPENDS}, like this: 713 714 version.c: ${_NETBSD_VERSION_DEPENDS} 715 commands to create version.c 716 717BSDSRCDIR The real path to the system sources, so that 'make obj' 718 will work correctly.

[${MACHINE}] 833 834Additionally, the following variables may be set by <bsd.own.mk> or in a 835make configuration file to modify the behavior of the system build 836process (default values are in brackets along with comments, if set by 837<bsd.own.mk>): 838 839USETOOLS Indicates whether the tools specified by ${TOOLDIR} should 840 be used as part of a build in progress. 841 Supported values: 842 843 yes Use the tools from TOOLDIR. 844 Must be set to this if cross-compiling. 845 846 no Do not use the tools from TOOLDIR, but refuse to 847 build native compilation tool components that are 848 version-specific for that tool. 849 850 never Do not use the tools from TOOLDIR, even when 851 building native tool components. This is similar to 852 the traditional NetBSD build method, but does not 853 verify that the compilation tools in use are 854 up-to-date enough in order to build the tree 855 successfully. This may cause build or runtime 856 problems when building the whole NetBSD source tree. 857 858 Default: "yes" if building all or part of a whole NetBSD 859 source tree (detected automatically); "no" otherwise 860 (to preserve traditional semantics of the <bsd.*.mk> 861 make(1) include files). 862 863OBJECT_FMT Object file format. [set to "ELF" on architectures that 864 use ELF -- currently all architectures]. 865 866KERNEL_DIR Install the kernel as /netbsd/kernel and the modules 867 in /netbsd/modules, defaults to "no". 868 869TOOLCHAIN_MISSING 870 If not "no", this indicates that the platform being built 871 does not have a working in-tree toolchain. If the 872 ${MACHINE_ARCH} in question falls into this category, 873 TOOLCHAIN_MISSING is conditionally assigned the value "yes". 874 Otherwise, the variable is unconditionally assigned the 875 value "no". 876 If not "no", ${MKBINUTILS}, ${MKGCC}, and ${MKGDB} are 877 unconditionally assigned the value "no". 878 879EXTERNAL_TOOLCHAIN 880 This variable is not directly set by <bsd.own.mk>, but 881 including <bsd.own.mk> is the canonical way to gain 882 access to this variable. The variable should be defined 883 either in the user's environment or in the user's mk.conf 884 file. If defined, this variable indicates the root of 885 an external toolchain which will be used to build the 886 tree. For example, if a platform is a ${TOOLCHAIN_MISSING} 887 platform, EXTERNAL_TOOLCHAIN can be used to re-enable the 888 cross-compile framework. 889 890 If EXTERNAL_TOOLCHAIN is defined, ${MKGCC} is unconditionally 891 assigned the value "no", since the external version of the 892 compiler may not be able to build the library components of 893 the in-tree compiler. 894 895 This variable should be used in conjunction with an appropiate 896 HAVE_GCC or HAVE_LLVM setting to control the compiler flags. 897 898 NOTE: This variable is not yet used in as many places as 899 it should be. Expect the exact semantics of this variable 900 to change in the short term as parts of the cross-compile 901 framework continue to be cleaned up. 902 903The following variables are defined to commands to perform the 904appropriate operation, with the default in [brackets].

This keeps those definitions in 1060centralized place. 1061 1062<bsd.own.mk> is generally useful when building your own Makefiles so that 1063they use the same default owners etc. as the rest of the tree. 1064 1065 1066=-=-=-=-= bsd.clean.mk =-=-=-=-= 1067 1068The include file <bsd.clean.mk> defines the clean and cleandir 1069targets. It uses the following variables: 1070 1071CLEANFILES Files to remove for both the clean and cleandir targets. 1072 1073CLEANDIRFILES Files to remove for the cleandir target, but not for 1074 the clean target. 1075 1076MKCLEANSRC Controls whether or not the clean and cleandir targets 1077 will delete files from both the object directory, 1078 ${.OBJDIR}, and the source directory, ${.CURDIR}. 1079 1080 If MKCLEANSRC is set to "no", then the file names in 1081 CLEANFILES or CLEANDIRFILES are interpreted relative 1082 to the object directory, ${.OBJDIR}. This is the 1083 traditional behaviour. 1084 1085 If MKCLEANSRC is set to "yes", then the file deletion 1086 is performed relative to both the object directory, 1087 ${.OBJDIR}, and the source directory, ${.CURDIR}. (This 1088 has no effect if ${.OBJDIR} is the same as ${.CURDIR}.) 1089 Deleting files from ${.CURDIR} is intended to remove 1090 stray output files that had been left in the source 1091 directory by an earlier build that did not use object 1092 directories. 1093 1094 The default is MKCLEANSRC=yes. If you always build with 1095 separate object directories, and you are sure that there 1096 are no stray files in the source directories, then you 1097 may set MKCLEANSRC=no to save some time. 1098 1099MKCLEANVERIFY Controls whether or not the clean and cleandir targets 1100 will verify that files have been deleted. 1101 1102 If MKCLEANVERIFY is set to "no", then the files will 1103 be deleted using a "rm -f" command, and its success or 1104 failure will be ignored. 1105 1106 If MKCLEANVERIFY is set to "yes", then the success of 1107 the "rm -f" command will be verified using an "ls" 1108 command. 1109 1110 The default is MKCLEANVERIFY=yes. If you are sure that 1111 there will be no problems caused by file permissions, 1112 read-only file systems, or the like, then you may set 1113 MKCLEANVERIFY=no to save some time. 1114 1115To use the clean and cleandir targets defined in <bsd.clean.mk>, other 1116Makefiles or bsd.*.mk files should append file names to the CLEANFILES 1117or CLEANDIRFILES variables. For example: 1118 1119 CLEANFILES+= a.out 1120 CLEANDIRFILES+= .depend 1121 1122 .include <bsd.clean.mk> 1123 1124The files listed in CLEANFILES and CLEANDIRFILES must not be 1125directories, because the potential risk from running "rm -rf" commands 1126in bsd.clean.mk is considered too great. If you want to recursively 1127delete a directory as part of "make clean" or "make cleandir" then you 1128need to provide your own target. 1129 1130=-=-=-=-= bsd.dep.mk =-=-=-=-= 1131 1132The include file <bsd.dep.mk> contains the default targets for building 1133.depend files. It creates .d files from entries in SRCS and DPSRCS 1134that are C, C++, or Objective C source files, and builds .depend from the 1135.d files. All other files in SRCS and all of DPSRCS will be used as 1136dependencies for the .d files. In order for this to function correctly, 1137it should be .included after all other .mk files and directives that may 1138modify SRCS or DPSRCS. It uses the following variables: 1139 1140SRCS List of source files to build the program. 1141 1142DPSRCS List of source files which are needed for generating 1143 dependencies, but are not needed in ${SRCS}. 1144 1145 1146=-=-=-=-= bsd.files.mk =-=-=-=-= 1147 1148The include file <bsd.files.mk> handles the FILES variables and is included 1149from <bsd.lib.mk> and <bsd.prog.mk>, and uses the following variables: 1150 1151FILES The list of files to install. 1152 1153CONFIGFILES Similar semantics to FILES, except that the files 1154 are installed by the `configinstall' target, 1155 not the `install' target. 1156 The FILES* variables documented below also apply. 1157 1158FILESOWN File owner. [${BINOWN}] 1159 1160FILESGRP File group. [${BINGRP}] 1161 1162FILESMODE File mode. [${NONBINMODE}] 1163 1164FILESDIR The location to install the files. 1165 1166FILESNAME Optional name to install each file as. 1167 1168FILESOWN_<fn> File owner of the specific file <fn>. 1169 1170FILESGRP_<fn> File group of the specific file <fn>. 1171 1172FILESMODE_<fn> File mode of the specific file <fn>. 1173 1174FILESDIR_<fn> The location to install the specific file <fn>. 1175 1176FILESNAME_<fn> Optional name to install <fn> as. 1177 1178FILESBUILD If this variable is defined, then its value will be 1179 used as the default for all FILESBUILD_<fn> variables. 1180 Otherwise, the default will be "no". 1181 1182FILESBUILD_<fn> A value different from "no" will add the file to the list of 1183 targets to be built by `realall'. Users of that variable 1184 should provide a target to build the file. 1185 1186 1187BUILDSYMLINKS List of two word items: 1188 lnsrc lntgt 1189 For each lnsrc item, create a symlink named lntgt. 1190 The lntgt symlinks are removed by the cleandir target. 1191 1192UUDECODE_FILES List of files which are stored as <file>.uue in the source 1193 tree. Each one will be decoded with ${TOOL_UUDECODE}. 1194 The source files have a `.uue' suffix, the generated files do 1195 not. 1196 1197UUDECODE_FILES_RENAME_<fn> 1198 Rename the output from the decode to the provided name. 1199 1200 *NOTE: These files are simply decoded, with no install or other 1201 rule applying implicitly except being added to the clean 1202 target. 1203 1204=-=-=-=-= bsd.gcc.mk =-=-=-=-= 1205 1206The include file <bsd.gcc.mk> computes various parameters related to GCC 1207support libraries. It defines no targets. <bsd.own.mk> MUST be included 1208before <bsd.gcc.mk>. 1209 1210The primary users of <bsd.gcc.mk> are <bsd.prog.mk> and <bsd.lib.mk>, each 1211of which need to know where to find certain GCC support libraries. 1212 1213The behavior of <bsd.gcc.mk> is influenced by the EXTERNAL_TOOLCHAIN variable, 1214which is generally set by the user. If EXTERNAL_TOOLCHAIN it set, then 1215the compiler is asked where to find the support libraries, otherwise the 1216support libraries are found in ${DESTDIR}/usr/lib. 1217 1218<bsd.gcc.mk> sets the following variables: 1219 1220_GCC_CRTBEGIN The full path name to crtbegin.o. 1221 1222_GCC_CRTBEGINS The full path name to crtbeginS.o. 1223 1224_GCC_CRTEND The full path name to crtend.o. 1225 1226_GCC_CRTENDS The full path name to crtendS.o. 1227 1228_GCC_LIBGCCDIR The directory where libgcc.a is located. 1229 1230 1231=-=-=-=-= bsd.inc.mk =-=-=-=-= 1232 1233The include file <bsd.inc.mk> defines the includes target and uses the 1234variables: 1235 1236INCS The list of include files. 1237 1238INCSDIR The location to install the include files. 1239 1240INCSNAME Target name of the include file, if only one; same as 1241 FILESNAME, but for include files. 1242 1243INCSYMLINKS Similar to SYMLINKS in <bsd.links.mk>, except that these 1244 are installed in the 'includes' target and not the 1245 (much later) 'install' target. 1246 1247INCSNAME_<file> The name file <file> should be installed as, if not <file>, 1248 same as FILESNAME_<file>, but for include files. 1249 1250 1251=-=-=-=-= bsd.info.mk =-=-=-=-= 1252 1253The include file <bsd.info.mk> is used to generate and install GNU Info 1254documentation from respective Texinfo source files. It defines three 1255implicit targets (.txi.info, .texi.info, and .texinfo.info), and uses the 1256following variables: 1257 1258TEXINFO List of Texinfo source files. Info documentation will 1259 consist of single files with the extension replaced by 1260 .info. 1261 1262INFOFLAGS Flags to pass to makeinfo. [] 1263 1264 1265=-=-=-=-= bsd.kernobj.mk =-=-=-=-= 1266 1267The include file <bsd.kernobj.mk> defines variables related to the 1268location of kernel sources and object directories. 1269 1270KERNSRCDIR Is the location of the top of the kernel src. 1271 [${_SRC_TOP_}/sys] 1272 1273KERNARCHDIR Is the location of the machine dependent kernel sources. 1274 [arch/${MACHINE}] 1275 1276KERNCONFDIR Is where the configuration files for kernels are found. 1277 [${KERNSRCDIR}/${KERNARCHDIR}/conf] 1278 1279KERNOBJDIR Is the kernel build directory. The kernel GENERIC for 1280 instance will be compiled in ${KERNOBJDIR}/GENERIC. 1281 The default value is 1282 ${MAKEOBJDIRPREFIX}${KERNSRCDIR}/${KERNARCHDIR}/compile 1283 if it exists or the target 'obj' is being made. 1284 Otherwise the default is 1285 ${KERNSRCDIR}/${KERNARCHDIR}/compile. 1286 1287It is important that Makefiles (such as those under src/distrib) that 1288wish to find compiled kernels use <bsd.kernobj.mk> and ${KERNOBJDIR} 1289rather than make assumptions about the location of the compiled kernel. 1290 1291 1292=-=-=-=-= bsd.kinc.mk =-=-=-=-= 1293 1294The include file <bsd.kinc.mk> defines the many targets (includes, 1295subdirectories, etc.), and is used by kernel makefiles to handle 1296include file installation. It is intended to be included alone, by 1297kernel Makefiles. It uses similar variables to <bsd.inc.mk>. 1298Please see <bsd.kinc.mk> for more details, and keep the documentation 1299in that file up to date. 1300 1301=-=-=-=-= bsd.syscall.mk =-=-=-=-= 1302 1303The include file <bsd.syscall.mk> contains the logic to create syscall 1304files for various emulations. It includes <bsd.kinc.mk> to handle the 1305rest of the targets. 1306 1307=-=-=-=-= bsd.lib.mk =-=-=-=-= 1308 1309The include file <bsd.lib.mk> has support for building libraries. It has 1310the same eight targets as <bsd.prog.mk>: all, clean, cleandir, depend, 1311includes, install, lint, and tags. Additionally, it has a checkver target 1312which checks for installed shared object libraries whose version is greater 1313that the version of the source. It has a limited number of suffixes, 1314consistent with the current needs of the BSD tree. <bsd.lib.mk> includes 1315<bsd.shlib.mk> to get shared library parameters. 1316 1317It sets/uses the following variables: 1318 1319LIB The name of the library to build. 1320 1321LIBDIR Target directory for libraries. 1322 1323MKARZERO Normally, ar(1) sets the timestamps, uid, gid and 1324 permissions in files inside its archives to those of 1325 the file it was fed. This leads to non-reproducible 1326 builds. If MKARZERO is set to "yes" (default is the 1327 same as MKREPRO, or "no" if MKREPRO is not defined), 1328 then the "D" flag is passed to ar, causing the 1329 timestamp, uid and gid to be zeroed and the file 1330 permissions to be set to 644. This allows .a files 1331 from different builds to be bit identical. 1332 1333SHLIBINSTALLDIR Target directory for shared libraries if ${USE_SHLIBDIR} 1334 is not "no". 1335 1336SHLIB_MAJOR 1337SHLIB_MINOR 1338SHLIB_TEENY Major, minor, and teeny version numbers of shared library 1339 1340USE_SHLIBDIR If not "no", use ${SHLIBINSTALLDIR} instead of ${LIBDIR} 1341 as the path to install shared libraries to. 1342 USE_SHLIBDIR must be defined before <bsd.own.mk> is included. 1343 Default: no 1344 1345LIBISMODULE If not "no", install as ${LIB}.so (without the "lib" prefix), 1346 and act as "MKDEBUGLIB=no MKPICINSTALL=no MKPROFILE=no 1347 MKSTATICLIB=no". Also do not install the lint library. 1348 Default: no 1349 1350LIBISPRIVATE If not "no", act as "MKDEBUGLIB=no MKPIC=no MKPROFILE=no", 1351 and don't install the (.a) library or the lint library. 1352 This is useful for "build only" helper libraries. 1353 If set to "pic", then a _pic.a library is also produced, 1354 so that it can be incorporated into other shared objects. 1355 Default: no 1356 1357LIBISCXX If not "no", Use ${CXX} instead of ${CC} to link 1358 shared libraries. 1359 This is useful for C++ libraries. 1360 Default: no 1361 1362LINTLIBDIR Target directory for lint libraries. 1363 1364LIBGRP Library group. 1365 1366LIBOWN Library owner. 1367 1368LIBMODE Library mode. 1369 1370LDADD Additional loader objects. 1371 1372MAN The manual pages to be installed (use a .1 - .9 suffix). 1373 1374NOCHECKVER_<library> 1375NOCHECKVER If set, disables checking for installed shared object 1376 libraries with versions greater than the source. A 1377 particular library name, without the "lib" prefix, may 1378 be appended to the variable name to disable the check for 1379 only that library. 1380 1381SRCS List of source files to build the library. Suffix types 1382 .s, .c, and .f are supported. Note, .s files are preferred 1383 to .c files of the same name. (This is not the default for 1384 versions of make.) 1385 1386LIBDPLIBS/ 1387PROGDPLIBS A list of the tuples: 1388 libname path-to-srcdir-of-libname 1389 1390 Instead of depending on installed versions of the libraries, 1391 one can depend on their built version in the source directory. 1392 This is useful for finding private libraries (LIBISPRIVATE). 1393 1394 For each tuple; 1395 * LIBDO.libname contains the .OBJDIR of the library 1396 `libname', and if it is not set it is determined 1397 from the srcdir and added to MAKEOVERRIDES (the 1398 latter is to allow for build time optimization). 1399 * LDADD gets -L${LIBDO.libname} -llibname added. 1400 * DPADD gets ${LIBDO.libname}/liblibname.so or 1401 ${LIBDO.libname}/liblibname.a added. 1402 1403 The special value "_external" for LIBDO.lib makes the 1404 build system to assume the library comes from outside 1405 of the NetBSD source tree and only causes -llibname 1406 to be added to LDADD. 1407 1408 This variable may be used for individual libraries/programs, 1409 as well as in parent directories to cache common libraries 1410 as a build-time optimization. 1411 1412The include file <bsd.lib.mk> includes the file named "../Makefile.inc" 1413if it exists, as well as the include file <bsd.man.mk>. 1414 1415It has rules for building profiled objects; profiled libraries are 1416built by default. 1417 1418Libraries are ranlib'd when made. 1419 1420 1421=-=-=-=-= bsd.links.mk =-=-=-=-= 1422 1423The include file <bsd.links.mk> handles the LINKS and SYMLINKS variables 1424and is included from <bsd.lib.mk> and <bsd.prog.mk>. 1425 1426LINKSOWN, LINKSGRP, and LINKSMODE, are relevant only if a metadata log 1427is used. The defaults may be modified by other bsd.*.mk files which 1428include bsd.links.mk. In the future, these variables may be replaced 1429by a method for explicitly recording hard links in a metadata log. 1430 1431LINKS The list of hard links, consisting of pairs of paths: 1432 source-file target-file 1433 ${DESTDIR} is prepended to both paths before linking. 1434 For example, to link /bin/test and /bin/[, use: 1435 LINKS=/bin/test /bin/[ 1436 1437CONFIGLINKS Similar semantics to LINKS, except that the links 1438 are installed by the `configinstall' target, 1439 not the `install' target. 1440 1441SYMLINKS The list of symbolic links, consisting of pairs of paths: 1442 source-file target-file 1443 ${DESTDIR} is only prepended to target-file before linking. 1444 For example, to symlink /usr/bin/tar to /bin/tar resulting 1445 in ${DESTDIR}/usr/bin/tar -> /bin/tar: 1446 SYMLINKS=/bin/tar /usr/bin/tar 1447 1448CONFIGSYMLINKS Similar semantics to SYMLINKS, except that the symbolic links 1449 are installed by the `configinstall' target, 1450 not the `install' target. 1451 1452LINKSOWN Link owner. [${BINOWN}] 1453 1454LINKSGRP Link group. [${BINGRP}] 1455 1456LINKSMODE Link mode. [${NONBINMODE}] 1457 1458LINKSOWN_<fn> Link owner of the specific file <fn>. 1459 1460LINKSGRP_<fn> Link group of the specific file <fn>. 1461 1462LINKSMODE_<fn> Link mode of the specific file <fn>. 1463 1464 1465=-=-=-=-= bsd.man.mk =-=-=-=-= 1466 1467The include file <bsd.man.mk> handles installing manual pages and their 1468links. 1469 1470It has a three targets: 1471 1472 catinstall: 1473 Install the preformatted manual pages and their links. 1474 htmlinstall: 1475 Install the HTML manual pages and their links. 1476 maninstall: 1477 Install the manual page sources and their links. 1478 1479It sets/uses the following variables: 1480 1481MANDIR Base path for manual installation. 1482 1483MANGRP Manual group. 1484 1485MANOWN Manual owner. 1486 1487MANMODE Manual mode. 1488 1489MANSUBDIR Subdirectory under the manual page section, i.e. "/vax" 1490 or "/tahoe" for machine specific manual pages. 1491 1492MAN The manual pages to be installed (use a .1 - .9 suffix). 1493 1494MLINKS List of manual page links (using a .1 - .9 suffix). The 1495 linked-to file must come first, the linked file second, 1496 and there may be multiple pairs. 1497 1498The include file <bsd.man.mk> includes a file named "../Makefile.inc" if 1499it exists. 1500 1501 1502=-=-=-=-= bsd.obj.mk =-=-=-=-= 1503 1504The include file <bsd.obj.mk> defines targets related to the creation 1505and use of separated object and source directories. 1506 1507If an environment variable named MAKEOBJDIRPREFIX is set, make(1) uses 1508${MAKEOBJDIRPREFIX}${.CURDIR} as the name of the object directory if 1509it exists. Otherwise make(1) looks for the existence of a 1510subdirectory (or a symlink to a directory) of the source directory 1511into which built targets should be placed. If an environment variable 1512named MAKEOBJDIR is set, make(1) uses its value as the name of the 1513object directory; failing that, make first looks for a subdirectory 1514named "obj.${MACHINE}", and if that doesn't exist, it looks for "obj". 1515 1516Object directories are not created automatically by make(1) if they 1517don't exist; you need to run a separate "make obj". (This will happen 1518during a top-level build if "MKOBJDIRS" is set to a value other than 1519"no"). When the source directory is a subdirectory of ${BSDSRCDIR} -- 1520and this is determined by a simple string prefix comparison -- object 1521directories are created in a separate object directory tree, and a 1522symlink to the object directory in that tree is created in the source 1523directory; otherwise, "make obj" assumes that you're not in the main 1524source tree and that it's not safe to use a separate object tree. 1525 1526Several variables used by <bsd.obj.mk> control exactly what 1527directories and links get created during a "make obj": 1528 1529MAKEOBJDIR If set, this is the component name of the object 1530 directory. 1531 1532OBJMACHINE If this is set but MAKEOBJDIR is not set, creates 1533 object directories or links named "obj.${MACHINE}"; 1534 otherwise, just creates ones named "obj". 1535 1536OBJMACHINE_ARCH If set with OBJMACHINE, creates object directories or 1537 links named "obj.${MACHINE}-${MACHINE_ARCH}". 1538 1539USR_OBJMACHINE If set, and the current directory is a subdirectory of 1540 ${BSDSRCDIR}, create object directory in the 1541 corresponding subdirectory of ${BSDOBJDIR}.${MACHINE}; 1542 otherwise, create it in the corresponding subdirectory 1543 of ${BSDOBJDIR} 1544 1545BUILDID If set, the contents of this variable are appended 1546 to the object directory name. If OBJMACHINE is also 1547 set, ".${BUILDID}" is added after ".${MACHINE}". 1548 1549 1550=-=-=-=-= bsd.prog.mk =-=-=-=-= 1551 1552The include file <bsd.prog.mk> handles building programs from one or 1553more source files, along with their manual pages. It has a limited number 1554of suffixes, consistent with the current needs of the BSD tree. 1555<bsd.prog.mk> includes <bsd.shlib.mk> to get shared library parameters. 1556 1557It has eight targets: 1558 1559 all: 1560 build the program and its manual page. This also 1561 creates a GDB initialization file (.gdbinit) in 1562 the objdir. The .gdbinit file sets the shared library 1563 prefix to ${DESTDIR} to facilitate cross-debugging. 1564 clean: 1565 remove the program, any object files and the files a.out, 1566 Errs, errs, mklog, and ${PROG}.core. 1567 cleandir: 1568 remove all of the files removed by the target clean, as 1569 well as .depend, tags, and any manual pages. 1570 `distclean' is a synonym for `cleandir'. 1571 depend: 1572 make the dependencies for the source files, and store 1573 them in the file .depend. 1574 includes: 1575 install any header files. 1576 install: 1577 install the program and its manual pages; if the Makefile 1578 does not itself define the target install, the targets 1579 beforeinstall and afterinstall may also be used to cause 1580 actions immediately before and after the install target 1581 is executed. 1582 lint: 1583 run lint on the source files 1584 tags: 1585 create a tags file for the source files. 1586 1587It sets/uses the following variables: 1588 1589BINGRP Binary group. 1590 1591BINOWN Binary owner. 1592 1593BINMODE Binary mode. 1594 1595CLEANDIRFILES Additional files to remove for the cleandir target. 1596 1597CLEANFILES Additional files to remove for the clean and cleandir targets. 1598 1599CONFIGOPTS Additional flags to config(1) when building kernels. 1600 1601COPTS Additional flags to the compiler when creating C objects. 1602 1603COPTS.<fn> Additional flags to the compiler when creating the 1604 C objects for <fn>. 1605 For <fn>.[ly], "<fn>.c" must be used. 1606 1607CPUFLAGS Additional flags to the compiler/assembler to select 1608 CPU instruction set options, CPU tuning options, etc. 1609 1610CPUFLAGS.<fn> Additional flags to the compiler/assembler for <fn>. 1611 For <fn>.[ly], "<fn>.c" must be used. 1612 1613CPPFLAGS Additional flags to the C pre-processor. 1614 1615CPPFLAGS.<fn> Additional flags to the C pre-processor for <fn>. 1616 For <fn>.[ly], "<fn>.c" must be used. 1617 1618GDBINIT List of GDB initialization files to add to "source" 1619 directives in the .gdbinit file that is created in the 1620 objdir. 1621 1622LDADD Additional loader objects. Usually used for libraries. 1623 For example, to load with the compatibility and utility 1624 libraries, use: 1625 1626 LDADD+=-lutil -lcompat 1627 1628LDFLAGS Additional linker flags (passed to ${CC} during link). 1629 1630LINKS See <bsd.links.mk> 1631 1632OBJCOPTS Additional flags to the compiler when creating ObjC objects. 1633 1634OBJCOPTS.<fn> Additional flags to the compiler when creating the 1635 ObjC objects for <fn>. 1636 For <fn>.[ly], "<fn>.c" must be used. 1637 1638SYMLINKS See <bsd.links.mk> 1639 1640MAN Manual pages (should end in .1 - .9). If no MAN variable is 1641 defined, "MAN=${PROG}.1" is assumed. 1642 1643PAXCTL_FLAGS If defined, run paxctl(1) on the program binary after link 1644 time, with the value of this variable as args to paxctl(1). 1645 1646PAXCTL_FLAGS.${PROG} Custom override for PAXCTL_FLAGS. 1647 1648PROG The name of the program to build. If not supplied, nothing 1649 is built. 1650 1651PROG_CXX If defined, the name of the program to build. Also 1652 causes <bsd.prog.mk> to link the program with the C++ 1653 compiler rather than the C compiler. PROG_CXX overrides 1654 the value of PROG if PROG is also set. 1655 1656PROGNAME The name that the above program will be installed as, if 1657 different from ${PROG}. 1658 1659PROGS Multiple programs to build from a single directory. 1660 Defaults to PROG. For each program ${_P} in ${PROGS}, 1661 uses SRCS.${_P}, defaulting to ${_P}.c. 1662 1663PROGS_CXX Multiple C++ programs to build from a single directory. 1664 Defaults to PROG_CXX. For each program ${_P} in ${PROGS_CXX}, 1665 uses SRCS.${_P}, defaulting to ${_P}.cc. 1666 1667SRCS List of source files to build the program. If SRCS is not 1668 defined, it's assumed to be ${PROG}.c or ${PROG_CXX}.cc. 1669 1670DPSRCS List of source files which are needed for generating 1671 dependencies, but are not needed in ${SRCS}. 1672 1673DPADD Additional dependencies for the program. Usually used for 1674 libraries. For example, to depend on the compatibility and 1675 utility libraries use: 1676 1677 DPADD+=${LIBCOMPAT} ${LIBUTIL} 1678 1679 The following system libraries are predefined for DPADD: 1680 1681
