Makefile

   1 # The default target of this Makefile is...
   2 all::
   3
   4 # Define V=1 to have a more verbose compile.
   5 #
   6 # Define SHELL_PATH to a POSIX shell if your /bin/sh is broken.
   7 #
   8 # Define SANE_TOOL_PATH to a colon-separated list of paths to prepend
   9 # to PATH if your tools in /usr/bin are broken.
  10 #
  11 # Define SOCKLEN_T to a suitable type (such as 'size_t') if your
  12 # system headers do not define a socklen_t type.
  13 #
  14 # Define INLINE to a suitable substitute (such as '__inline' or '') if git
  15 # fails to compile with errors about undefined inline functions or similar.
  16 #
  17 # Define SNPRINTF_RETURNS_BOGUS if you are on a system which snprintf()
  18 # or vsnprintf() return -1 instead of number of characters which would
  19 # have been written to the final string if enough space had been available.
  20 #
  21 # Define FREAD_READS_DIRECTORIES if you are on a system which succeeds
  22 # when attempting to read from an fopen'ed directory (or even to fopen
  23 # it at all).
  24 #
  25 # Define OPEN_RETURNS_EINTR if your open() system call may return EINTR
  26 # when a signal is received (as opposed to restarting).
  27 #
  28 # Define NO_OPENSSL environment variable if you do not have OpenSSL.
  29 #
  30 # Define USE_LIBPCRE if you have and want to use libpcre. Various
  31 # commands such as log and grep offer runtime options to use
  32 # Perl-compatible regular expressions instead of standard or extended
  33 # POSIX regular expressions.
  34 #
  35 # Only libpcre version 2 is supported. USE_LIBPCRE2 is a synonym for
  36 # USE_LIBPCRE, support for the old USE_LIBPCRE1 has been removed.
  37 #
  38 # Define LIBPCREDIR=/foo/bar if your PCRE header and library files are
  39 # in /foo/bar/include and /foo/bar/lib directories.
  40 #
  41 # Define HAVE_ALLOCA_H if you have working alloca(3) defined in that header.
  42 #
  43 # Define NO_CURL if you do not have libcurl installed.  git-http-fetch and
  44 # git-http-push are not built, and you cannot use http:// and https://
  45 # transports (neither smart nor dumb).
  46 #
  47 # Define CURLDIR=/foo/bar if your curl header and library files are in
  48 # /foo/bar/include and /foo/bar/lib directories.
  49 #
  50 # Define CURL_CONFIG to curl's configuration program that prints information
  51 # about the library (e.g., its version number).  The default is 'curl-config'.
  52 #
  53 # Define CURL_LDFLAGS to specify flags that you need to link when using libcurl,
  54 # if you do not want to rely on the libraries provided by CURL_CONFIG.  The
  55 # default value is a result of `curl-config --libs`.  An example value for
  56 # CURL_LDFLAGS is as follows:
  57 #
  58 #     CURL_LDFLAGS=-lcurl
  59 #
  60 # Define NO_EXPAT if you do not have expat installed.  git-http-push is
  61 # not built, and you cannot push using http:// and https:// transports (dumb).
  62 #
  63 # Define EXPATDIR=/foo/bar if your expat header and library files are in
  64 # /foo/bar/include and /foo/bar/lib directories.
  65 #
  66 # Define EXPAT_NEEDS_XMLPARSE_H if you have an old version of expat (e.g.,
  67 # 1.1 or 1.2) that provides xmlparse.h instead of expat.h.
  68 #
  69 # Define NO_GETTEXT if you don't want Git output to be translated.
  70 # A translated Git requires GNU libintl or another gettext implementation,
  71 # plus libintl-perl at runtime.
  72 #
  73 # Define USE_GETTEXT_SCHEME and set it to 'fallthrough', if you don't trust
  74 # the installed gettext translation of the shell scripts output.
  75 #
  76 # Define HAVE_LIBCHARSET_H if you haven't set NO_GETTEXT and you can't
  77 # trust the langinfo.h's nl_langinfo(CODESET) function to return the
  78 # current character set. GNU and Solaris have a nl_langinfo(CODESET),
  79 # FreeBSD can use either, but MinGW and some others need to use
  80 # libcharset.h's locale_charset() instead.
  81 #
  82 # Define CHARSET_LIB to the library you need to link with in order to
  83 # use locale_charset() function.  On some platforms this needs to set to
  84 # -lcharset, on others to -liconv .
  85 #
  86 # Define LIBC_CONTAINS_LIBINTL if your gettext implementation doesn't
  87 # need -lintl when linking.
  88 #
  89 # Define NO_MSGFMT_EXTENDED_OPTIONS if your implementation of msgfmt
  90 # doesn't support GNU extensions like --check and --statistics
  91 #
  92 # Define HAVE_PATHS_H if you have paths.h and want to use the default PATH
  93 # it specifies.
  94 #
  95 # Define NO_D_TYPE_IN_DIRENT if your platform defines DT_UNKNOWN but lacks
  96 # d_type in struct dirent (Cygwin 1.5, fixed in Cygwin 1.7).
  97 #
  98 # Define HAVE_STRINGS_H if you have strings.h and need it for strcasecmp.
  99 #
 100 # Define NO_STRCASESTR if you don't have strcasestr.
 101 #
 102 # Define NO_MEMMEM if you don't have memmem.
 103 #
 104 # Define NO_GETPAGESIZE if you don't have getpagesize.
 105 #
 106 # Define NO_STRLCPY if you don't have strlcpy.
 107 #
 108 # Define NO_STRTOUMAX if you don't have both strtoimax and strtoumax in the
 109 # C library. If your compiler also does not support long long or does not have
 110 # strtoull, define NO_STRTOULL.
 111 #
 112 # Define NO_SETENV if you don't have setenv in the C library.
 113 #
 114 # Define NO_UNSETENV if you don't have unsetenv in the C library.
 115 #
 116 # Define NO_MKDTEMP if you don't have mkdtemp in the C library.
 117 #
 118 # Define MKDIR_WO_TRAILING_SLASH if your mkdir() can't deal with trailing slash.
 119 #
 120 # Define NO_GECOS_IN_PWENT if you don't have pw_gecos in struct passwd
 121 # in the C library.
 122 #
 123 # Define NO_LIBGEN_H if you don't have libgen.h.
 124 #
 125 # Define NEEDS_LIBGEN if your libgen needs -lgen when linking
 126 #
 127 # Define NO_SYS_SELECT_H if you don't have sys/select.h.
 128 #
 129 # Define NO_SYMLINK_HEAD if you never want .git/HEAD to be a symbolic link.
 130 # Enable it on Windows.  By default, symrefs are still used.
 131 #
 132 # Define NO_SVN_TESTS if you want to skip time-consuming SVN interoperability
 133 # tests.  These tests take up a significant amount of the total test time
 134 # but are not needed unless you plan to talk to SVN repos.
 135 #
 136 # Define NO_FINK if you are building on Darwin/Mac OS X, have Fink
 137 # installed in /sw, but don't want GIT to link against any libraries
 138 # installed there.  If defined you may specify your own (or Fink's)
 139 # include directories and library directories by defining CFLAGS
 140 # and LDFLAGS appropriately.
 141 #
 142 # Define NO_DARWIN_PORTS if you are building on Darwin/Mac OS X,
 143 # have DarwinPorts installed in /opt/local, but don't want GIT to
 144 # link against any libraries installed there.  If defined you may
 145 # specify your own (or DarwinPort's) include directories and
 146 # library directories by defining CFLAGS and LDFLAGS appropriately.
 147 #
 148 # Define NO_APPLE_COMMON_CRYPTO if you are building on Darwin/Mac OS X
 149 # and do not want to use Apple's CommonCrypto library.  This allows you
 150 # to provide your own OpenSSL library, for example from MacPorts.
 151 #
 152 # Define BLK_SHA1 environment variable to make use of the bundled
 153 # optimized C SHA1 routine.
 154 #
 155 # Define PPC_SHA1 environment variable when running make to make use of
 156 # a bundled SHA1 routine optimized for PowerPC.
 157 #
 158 # Define DC_SHA1 to unconditionally enable the collision-detecting sha1
 159 # algorithm. This is slower, but may detect attempted collision attacks.
 160 # Takes priority over other *_SHA1 knobs.
 161 #
 162 # Define DC_SHA1_EXTERNAL in addition to DC_SHA1 if you want to build / link
 163 # git with the external SHA1 collision-detect library.
 164 # Without this option, i.e. the default behavior is to build git with its
 165 # own built-in code (or submodule).
 166 #
 167 # Define DC_SHA1_SUBMODULE in addition to DC_SHA1 to use the
 168 # sha1collisiondetection shipped as a submodule instead of the
 169 # non-submodule copy in sha1dc/. This is an experimental option used
 170 # by the git project to migrate to using sha1collisiondetection as a
 171 # submodule.
 172 #
 173 # Define OPENSSL_SHA1 environment variable when running make to link
 174 # with the SHA1 routine from openssl library.
 175 #
 176 # Define SHA1_MAX_BLOCK_SIZE to limit the amount of data that will be hashed
 177 # in one call to the platform's SHA1_Update(). e.g. APPLE_COMMON_CRYPTO
 178 # wants 'SHA1_MAX_BLOCK_SIZE=1024L*1024L*1024L' defined.
 179 #
 180 # Define BLK_SHA256 to use the built-in SHA-256 routines.

 186 # Define NEEDS_CRYPTO_WITH_SSL if you need -lcrypto when using -lssl (Darwin).
 187 #
 188 # Define NEEDS_SSL_WITH_CRYPTO if you need -lssl when using -lcrypto (Darwin).
 189 #
 190 # Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
 191 #
 192 # Define NEEDS_LIBINTL_BEFORE_LIBICONV if you need libintl before libiconv.
 193 #
 194 # Define NO_INTPTR_T if you don't have intptr_t or uintptr_t.
 195 #
 196 # Define NO_UINTMAX_T if you don't have uintmax_t.
 197 #
 198 # Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
 199 # Patrick Mauritz).
 200 #
 201 # Define NEEDS_RESOLV if linking with -lnsl and/or -lsocket is not enough.
 202 # Notably on Solaris hstrerror resides in libresolv and on Solaris 7
 203 # inet_ntop and inet_pton additionally reside there.
 204 #
 205 # Define NO_MMAP if you want to avoid mmap.
 206 #
 207 # Define MMAP_PREVENTS_DELETE if a file that is currently mmapped cannot be
 208 # deleted or cannot be replaced using rename().
 209 #
 210 # Define NO_POLL_H if you don't have poll.h.
 211 #
 212 # Define NO_SYS_POLL_H if you don't have sys/poll.h.
 213 #
 214 # Define NO_POLL if you do not have or don't want to use poll().
 215 # This also implies NO_POLL_H and NO_SYS_POLL_H.
 216 #
 217 # Define NEEDS_SYS_PARAM_H if you need to include sys/param.h to compile,
 218 # *PLEASE* REPORT to git@vger.kernel.org if your platform needs this;
 219 # we want to know more about the issue.
 220 #
 221 # Define NO_PTHREADS if you do not have or do not want to use Pthreads.
 222 #
 223 # Define NO_PREAD if you have a problem with pread() system call (e.g.
 224 # cygwin1.dll before v1.5.22).
 225 #
 226 # Define NO_SETITIMER if you don't have setitimer()
 227 #
 228 # Define NO_STRUCT_ITIMERVAL if you don't have struct itimerval
 229 # This also implies NO_SETITIMER
 230 #
 231 # Define NO_FAST_WORKING_DIRECTORY if accessing objects in pack files is
 232 # generally faster on your platform than accessing the working directory.
 233 #
 234 # Define NO_TRUSTABLE_FILEMODE if your filesystem may claim to support
 235 # the executable mode bit, but doesn't really do so.
 236 #
 237 # Define CSPRNG_METHOD to "arc4random" if your system has arc4random and
 238 # arc4random_buf, "libbsd" if your system has those functions from libbsd,
 239 # "getrandom" if your system has getrandom, "getentropy" if your system has
 240 # getentropy, "rtlgenrandom" for RtlGenRandom (Windows only), or "openssl" if
 241 # you'd want to use the OpenSSL CSPRNG.  You may set multiple options with
 242 # spaces, in which case a suitable option will be chosen.  If unset or set to
 243 # anything else, defaults to using "/dev/urandom".
 244 #
 245 # Define NEEDS_MODE_TRANSLATION if your OS strays from the typical file type
 246 # bits in mode values (e.g. z/OS defines I_SFMT to 0xFF000000 as opposed to the
 247 # usual 0xF000).
 248 #
 249 # Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
 250 #
 251 # Define NO_UNIX_SOCKETS if your system does not offer unix sockets.

 259 # (input buffer pointer) parameter is declared with type (const char **).
 260 #
 261 # Define ICONV_OMITS_BOM if your iconv implementation does not write a
 262 # byte-order mark (BOM) when writing UTF-16 or UTF-32 and always writes in
 263 # big-endian format.
 264 #
 265 # Define NO_DEFLATE_BOUND if your zlib does not have deflateBound.
 266 #
 267 # Define NO_NORETURN if using buggy versions of gcc 4.6+ and profile feedback,
 268 # as the compiler can crash (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49299)
 269 #
 270 # Define USE_NSEC below if you want git to care about sub-second file mtimes
 271 # and ctimes. Note that you need recent glibc (at least 2.2.4) for this. On
 272 # Linux, kernel 2.6.11 or newer is required for reliable sub-second file times
 273 # on file systems with exactly 1 ns or 1 s resolution. If you intend to use Git
 274 # on other file systems (e.g. CEPH, CIFS, NTFS, UDF), don't enable USE_NSEC. See
 275 # Documentation/technical/racy-git.txt for details.
 276 #
 277 # Define USE_ST_TIMESPEC if your "struct stat" uses "st_ctimespec" instead of
 278 # "st_ctim"
 279 #
 280 # Define NO_NSEC if your "struct stat" does not have "st_ctim.tv_nsec"
 281 # available.  This automatically turns USE_NSEC off.
 282 #
 283 # Define USE_STDEV below if you want git to care about the underlying device
 284 # change being considered an inode change from the update-index perspective.
 285 #
 286 # Define NO_ST_BLOCKS_IN_STRUCT_STAT if your platform does not have st_blocks
 287 # field that counts the on-disk footprint in 512-byte blocks.
 288 #
 289 # Define GNU_ROFF if your target system uses GNU groff.  This forces
 290 # apostrophes to be ASCII so that cut&pasting examples to the shell
 291 # will work.
 292 #
 293 # Define USE_ASCIIDOCTOR to use Asciidoctor instead of AsciiDoc to build the
 294 # documentation.
 295 #
 296 # Define ASCIIDOCTOR_EXTENSIONS_LAB to point to the location of the Asciidoctor
 297 # Extensions Lab if you have it available.
 298 #
 299 # Define PERL_PATH to the path of your Perl binary (usually /usr/bin/perl).
 300 #
 301 # Define NO_PERL if you do not want Perl scripts or libraries at all.
 302 #
 303 # Define NO_PERL_CPAN_FALLBACKS if you do not want to install bundled
 304 # copies of CPAN modules that serve as a fallback in case the modules
 305 # are not available on the system. This option is intended for
 306 # distributions that want to use their packaged versions of Perl
 307 # modules, instead of the fallbacks shipped with Git.
 308 #
 309 # Define PYTHON_PATH to the path of your Python binary (often /usr/bin/python
 310 # but /usr/bin/python2.7 or /usr/bin/python3 on some platforms).
 311 #
 312 # Define NO_PYTHON if you do not want Python scripts or libraries at all.
 313 #
 314 # Define NO_TCLTK if you do not want Tcl/Tk GUI.
 315 #
 316 # The TCL_PATH variable governs the location of the Tcl interpreter
 317 # used to optimize git-gui for your system.  Only used if NO_TCLTK
 318 # is not set.  Defaults to the bare 'tclsh'.
 319 #
 320 # The TCLTK_PATH variable governs the location of the Tcl/Tk interpreter.
 321 # If not set it defaults to the bare 'wish'. If it is set to the empty
 322 # string then NO_TCLTK will be forced (this is used by configure script).
 323 #
 324 # Define INTERNAL_QSORT to use Git's implementation of qsort(), which
 325 # is a simplified version of the merge sort used in glibc. This is
 326 # recommended if Git triggers O(n^2) behavior in your platform's qsort().
 327 #
 328 # Define HAVE_ISO_QSORT_S if your platform provides a qsort_s() that's
 329 # compatible with the one described in C11 Annex K.
 330 #
 331 # Define UNRELIABLE_FSTAT if your system's fstat does not return the same
 332 # information on a not yet closed file that lstat would return for the same
 333 # file after it was closed.
 334 #
 335 # Define OBJECT_CREATION_USES_RENAMES if your operating systems has problems
 336 # when hardlinking a file to another name and unlinking the original file right
 337 # away (some NTFS drivers seem to zero the contents in that scenario).
 338 #
 339 # Define INSTALL_SYMLINKS if you prefer to have everything that can be
 340 # symlinked between bin/ and libexec/ to use relative symlinks between
 341 # the two. This option overrides NO_CROSS_DIRECTORY_HARDLINKS and
 342 # NO_INSTALL_HARDLINKS which will also use symlinking by indirection
 343 # within the same directory in some cases, INSTALL_SYMLINKS will
 344 # always symlink to the final target directly.
 345 #
 346 # Define NO_CROSS_DIRECTORY_HARDLINKS if you plan to distribute the installed
 347 # programs as a tar, where bin/ and libexec/ might be on different file systems.
 348 #
 349 # Define NO_INSTALL_HARDLINKS if you prefer to use either symbolic links or
 350 # copies to install built-in git commands e.g. git-cat-file.
 351 #
 352 # Define SKIP_DASHED_BUILT_INS if you do not need the dashed versions of the
 353 # built-ins to be linked/copied at all.
 354 #
 355 # Define USE_NED_ALLOCATOR if you want to replace the platforms default
 356 # memory allocators with the nedmalloc allocator written by Niall Douglas.
 357 #
 358 # Define OVERRIDE_STRDUP to override the libc version of strdup(3).
 359 # This is necessary when using a custom allocator in order to avoid
 360 # crashes due to allocation and free working on different 'heaps'.
 361 # It's defined automatically if USE_NED_ALLOCATOR is set.
 362 #
 363 # Define NO_REGEX if your C library lacks regex support with REG_STARTEND

 372 # Define CSSMIN to point to a CSS minifier in order to generate a minified
 373 # version of gitweb.css
 374 #
 375 # Define DEFAULT_PAGER to a sensible pager command (defaults to "less") if
 376 # you want to use something different.  The value will be interpreted by the
 377 # shell at runtime when it is used.
 378 #
 379 # Define DEFAULT_EDITOR to a sensible editor command (defaults to "vi") if you
 380 # want to use something different.  The value will be interpreted by the shell
 381 # if necessary when it is used.  Examples:
 382 #
 383 #   DEFAULT_EDITOR='~/bin/vi',
 384 #   DEFAULT_EDITOR='$GIT_FALLBACK_EDITOR',
 385 #   DEFAULT_EDITOR='"C:\Program Files\Vim\gvim.exe" --nofork'
 386 #
 387 # Define COMPUTE_HEADER_DEPENDENCIES to "yes" if you want dependencies on
 388 # header files to be automatically computed, to avoid rebuilding objects when
 389 # an unrelated header file changes.  Define it to "no" to use the hard-coded
 390 # dependency rules.  The default is "auto", which means to use computed header
 391 # dependencies if your compiler is detected to support it.
 392 #
 393 # Define NATIVE_CRLF if your platform uses CRLF for line endings.
 394 #
 395 # Define GIT_USER_AGENT if you want to change how git identifies itself during
 396 # network interactions.  The default is "git/$(GIT_VERSION)".
 397 #
 398 # Define DEFAULT_HELP_FORMAT to "man", "info" or "html"
 399 # (defaults to "man") if you want to have a different default when
 400 # "git help" is called without a parameter specifying the format.
 401 #
 402 # Define GIT_TEST_INDEX_VERSION to 2, 3 or 4 to run the test suite
 403 # with a different indexfile format version.  If it isn't set the index
 404 # file format used is index-v[23].
 405 #
 406 # Define GIT_TEST_UTF8_LOCALE to preferred utf-8 locale for testing.

 408 # locale returned by "locale -a".
 409 #
 410 # Define HAVE_CLOCK_GETTIME if your platform has clock_gettime.
 411 #
 412 # Define HAVE_CLOCK_MONOTONIC if your platform has CLOCK_MONOTONIC.
 413 #
 414 # Define NEEDS_LIBRT if your platform requires linking with librt (glibc version
 415 # before 2.17) for clock_gettime and CLOCK_MONOTONIC.
 416 #
 417 # Define HAVE_BSD_SYSCTL if your platform has a BSD-compatible sysctl function.
 418 #
 419 # Define HAVE_GETDELIM if your system has the getdelim() function.
 420 #

 424 # even if execution permission isn't granted for any user.
 425 #
 426 # Define PAGER_ENV to a SP separated VAR=VAL pairs to define
 427 # default environment variables to be passed when a pager is spawned, e.g.
 428 #
 429 #    PAGER_ENV = LESS=FRX LV=-c
 430 #
 431 # to say "export LESS=FRX (and LV=-c) if the environment variable
 432 # LESS (and LV) is not set, respectively".
 433 #
 434 # Define TEST_SHELL_PATH if you want to use a shell besides SHELL_PATH for
 435 # running the test scripts (e.g., bash has better support for "set -x"
 436 # tracing).
 437 #
 438 # When cross-compiling, define HOST_CPU as the canonical name of the CPU on
 439 # which the built Git will run (for instance "x86_64").
 440 #
 441 # Define RUNTIME_PREFIX to configure Git to resolve its ancillary tooling and
 442 # support files relative to the location of the runtime binary, rather than
 443 # hard-coding them into the binary. Git installations built with RUNTIME_PREFIX
 444 # can be moved to arbitrary filesystem locations. RUNTIME_PREFIX also causes
 445 # Perl scripts to use a modified entry point header allowing them to resolve
 446 # support files at runtime.
 447 #
 448 # When using RUNTIME_PREFIX, define HAVE_BSD_KERN_PROC_SYSCTL if your platform
 449 # supports the KERN_PROC BSD sysctl function.
 450 #
 451 # When using RUNTIME_PREFIX, define PROCFS_EXECUTABLE_PATH if your platform
 452 # mounts a "procfs" filesystem capable of resolving the path of the current
 453 # executable. If defined, this must be the canonical path for the "procfs"
 454 # current executable path.
 455 #
 456 # When using RUNTIME_PREFIX, define HAVE_NS_GET_EXECUTABLE_PATH if your platform
 457 # supports calling _NSGetExecutablePath to retrieve the path of the running
 458 # executable.
 459 #
 460 # When using RUNTIME_PREFIX, define HAVE_WPGMPTR if your platform offers
 461 # the global variable _wpgmptr containing the absolute path of the current
 462 # executable (this is the case on Windows).
 463 #
 464 # INSTALL_STRIP can be set to "-s" to strip binaries during installation,
 465 # if your $(INSTALL) command supports the option.
 466 #
 467 # Define GENERATE_COMPILATION_DATABASE to "yes" to generate JSON compilation
 468 # database entries during compilation if your compiler supports it, using the
 469 # `-MJ` flag. The JSON entries will be placed in the `compile_commands/`
 470 # directory, and the JSON compilation database 'compile_commands.json' will be
 471 # created at the root of the repository.
 472 #
 473 # If your platform supports a built-in fsmonitor backend, set
 474 # FSMONITOR_DAEMON_BACKEND to the "<name>" of the corresponding
 475 # `compat/fsmonitor/fsm-listen-<name>.c` and
 476 # `compat/fsmonitor/fsm-health-<name>.c` files
 477 # that implement the `fsm_listen__*()` and `fsm_health__*()` routines.
 478 #
 479 # If your platform has OS-specific ways to tell if a repo is incompatible with
 480 # fsmonitor (whether the hook or IPC daemon version), set FSMONITOR_OS_SETTINGS
 481 # to the "<name>" of the corresponding `compat/fsmonitor/fsm-settings-<name>.c`
 482 # that implements the `fsm_os_settings__*()` routines.
 483 #
 484 # Define DEVELOPER to enable more compiler warnings. Compiler version
 485 # and family are auto detected, but could be overridden by defining
 486 # COMPILER_FEATURES (see config.mak.dev). You can still set
 487 # CFLAGS="..." in combination with DEVELOPER enables, whether that's
 488 # for tweaking something unrelated (e.g. optimization level), or for
 489 # selectively overriding something DEVELOPER or one of the DEVOPTS
 490 # (see just below) brings in.
 491 #
 492 # When DEVELOPER is set, DEVOPTS can be used to control compiler
 493 # options.  This variable contains keywords separated by
 494 # whitespace. The following keywords are recognized:
 495 #
 496 #    no-error:
 497 #
 498 #        suppresses the -Werror that implicitly comes with
 499 #        DEVELOPER=1. Useful for getting the full set of errors
 500 #        without immediately dying, or for logging them.
 501 #
 502 #    extra-all:
 503 #
 504 #        The DEVELOPER mode enables -Wextra with a few exceptions. By
 505 #        setting this flag the exceptions are removed, and all of
 506 #        -Wextra is used.
 507 #
 508 #    no-pedantic:
 509 #
 510 #        Disable -pedantic compilation.

2233 ### Target-specific flags and dependencies
2234
2235 # The generic compilation pattern rule and automatically
2236 # computed header dependencies (falling back to a dependency on
2237 # LIB_H) are enough to describe how most targets should be built,
2238 # but some targets are special enough to need something a little
2239 # different.
2240 #
2241 # - When a source file "foo.c" #includes a generated header file,
2242 #   we need to list that dependency for the "foo.o" target.
2243 #
2244 #   We also list it from other targets that are built from foo.c
2245 #   like "foo.sp" and "foo.s", even though that is easy to forget
2246 #   to do because the generated header is already present around
2247 #   after a regular build attempt.
2248 #
2249 # - Some code depends on configuration kept in makefile
2250 #   variables. The target-specific variable EXTRA_CPPFLAGS can
2251 #   be used to convey that information to the C preprocessor
2252 #   using -D options.
2253 #
2254 #   The "foo.o" target should have a corresponding dependency on
2255 #   a file that changes when the value of the makefile variable
2256 #   changes.  For example, targets making use of the
2257 #   $(GIT_VERSION) variable depend on GIT-VERSION-FILE.
2258 #
2259 #   Technically the ".sp" and ".s" targets do not need this
2260 #   dependency because they are force-built, but they get the
2261 #   same dependency for consistency. This way, you do not have to
2262 #   know how each target is implemented. And it means the
2263 #   dependencies here will not need to change if the force-build
2264 #   details change some day.

3503 # are not necessarily appropriate for general builds, and that vary greatly

3507 #
3508 # make CC=clang CXX=clang++ \
3509 #      CFLAGS="-fsanitize=fuzzer-no-link,address" \
3510 #      LIB_FUZZING_ENGINE="-fsanitize=fuzzer" \
