   1 # The default target of this Makefile is...
   2 all::
   3
   4 # Import tree-wide shared Makefile behavior and libraries
   5 include shared.mak
   6
   7 # Define V=1 to have a more verbose compile.
   8 #
   9 # Define SHELL_PATH to a POSIX shell if your /bin/sh is broken.
  10 #
  11 # Define SANE_TOOL_PATH to a colon-separated list of paths to prepend
  12 # to PATH if your tools in /usr/bin are broken.
  13 #
  14 # Define SOCKLEN_T to a suitable type (such as 'size_t') if your
  15 # system headers do not define a socklen_t type.
  16 #
  17 # Define INLINE to a suitable substitute (such as '__inline' or '') if git
  18 # fails to compile with errors about undefined inline functions or similar.
  19 #
  20 # Define SNPRINTF_RETURNS_BOGUS if you are on a system which snprintf()
  21 # or vsnprintf() return -1 instead of number of characters which would
  22 # have been written to the final string if enough space had been available.
  23 #
  24 # Define FREAD_READS_DIRECTORIES if you are on a system which succeeds
  25 # when attempting to read from an fopen'ed directory (or even to fopen
  26 # it at all).
  27 #
  28 # Define OPEN_RETURNS_EINTR if your open() system call may return EINTR
  29 # when a signal is received (as opposed to restarting).
  30 #
  31 # Define NO_OPENSSL environment variable if you do not have OpenSSL.
  32 #
  33 # Define USE_LIBPCRE if you have and want to use libpcre. Various
  34 # commands such as log and grep offer runtime options to use
  35 # Perl-compatible regular expressions instead of standard or extended
  36 # POSIX regular expressions.
  37 #
  38 # Only libpcre version 2 is supported. USE_LIBPCRE2 is a synonym for
  39 # USE_LIBPCRE, support for the old USE_LIBPCRE1 has been removed.
  40 #
  41 # Define LIBPCREDIR=/foo/bar if your PCRE header and library files are
  42 # in /foo/bar/include and /foo/bar/lib directories.
  43 #
  44 # Define HAVE_ALLOCA_H if you have working alloca(3) defined in that header.
  45 #
  46 # Define NO_CURL if you do not have libcurl installed.  git-http-fetch and
  47 # git-http-push are not built, and you cannot use http:// and https://
  48 # transports (neither smart nor dumb).
  49 #
  50 # Define CURLDIR=/foo/bar if your curl header and library files are in
  51 # /foo/bar/include and /foo/bar/lib directories.
  52 #
  53 # Define CURL_CONFIG to curl's configuration program that prints information
  54 # about the library (e.g., its version number).  The default is 'curl-config'.
  55 #
  56 # Define CURL_LDFLAGS to specify flags that you need to link when using libcurl,
  57 # if you do not want to rely on the libraries provided by CURL_CONFIG.  The
  58 # default value is a result of `curl-config --libs`.  An example value for
  59 # CURL_LDFLAGS is as follows:
  60 #
  61 #     CURL_LDFLAGS=-lcurl
  62 #
  63 # Define NO_EXPAT if you do not have expat installed.  git-http-push is
  64 # not built, and you cannot push using http:// and https:// transports (dumb).

  66 # Define EXPATDIR=/foo/bar if your expat header and library files are in
  67 # /foo/bar/include and /foo/bar/lib directories.
  68 #
  69 # Define EXPAT_NEEDS_XMLPARSE_H if you have an old version of expat (e.g.,
  70 # 1.1 or 1.2) that provides xmlparse.h instead of expat.h.
  71 #
  72 # Define NO_GETTEXT if you don't want Git output to be translated.
  73 # A translated Git requires GNU libintl or another gettext implementation,
  74 # plus libintl-perl at runtime.
  75 #
  76 # Define USE_GETTEXT_SCHEME and set it to 'fallthrough', if you don't trust
  77 # the installed gettext translation of the shell scripts output.
  78 #
  79 # Define HAVE_LIBCHARSET_H if you haven't set NO_GETTEXT and you can't
  80 # trust the langinfo.h's nl_langinfo(CODESET) function to return the
  81 # current character set. GNU and Solaris have a nl_langinfo(CODESET),
  82 # FreeBSD can use either, but MinGW and some others need to use
  83 # libcharset.h's locale_charset() instead.
  84 #
  85 # Define CHARSET_LIB to the library you need to link with in order to
  86 # use locale_charset() function.  On some platforms this needs to set to
  87 # -lcharset, on others to -liconv .
  88 #
  89 # Define LIBC_CONTAINS_LIBINTL if your gettext implementation doesn't
  90 # need -lintl when linking.
  91 #
  92 # Define NO_MSGFMT_EXTENDED_OPTIONS if your implementation of msgfmt
  93 # doesn't support GNU extensions like --check and --statistics
  94 #
  95 # Define HAVE_PATHS_H if you have paths.h and want to use the default PATH
  96 # it specifies.
  97 #
  98 # Define NO_D_TYPE_IN_DIRENT if your platform defines DT_UNKNOWN but lacks
  99 # d_type in struct dirent (Cygwin 1.5, fixed in Cygwin 1.7).
 100 #
 101 # Define HAVE_STRINGS_H if you have strings.h and need it for strcasecmp.
 102 #
 103 # Define NO_STRCASESTR if you don't have strcasestr.
 104 #
 105 # Define NO_MEMMEM if you don't have memmem.
 106 #
 107 # Define NO_GETPAGESIZE if you don't have getpagesize.
 108 #
 109 # Define NO_STRLCPY if you don't have strlcpy.
 110 #
 111 # Define NO_STRTOUMAX if you don't have both strtoimax and strtoumax in the
 112 # C library. If your compiler also does not support long long or does not have
 113 # strtoull, define NO_STRTOULL.
 114 #
 115 # Define NO_SETENV if you don't have setenv in the C library.
 116 #
 117 # Define NO_UNSETENV if you don't have unsetenv in the C library.
 118 #
 119 # Define NO_MKDTEMP if you don't have mkdtemp in the C library.
 120 #
 121 # Define MKDIR_WO_TRAILING_SLASH if your mkdir() can't deal with trailing slash.
 122 #
 123 # Define NO_GECOS_IN_PWENT if you don't have pw_gecos in struct passwd
 124 # in the C library.
 125 #
 126 # Define NO_LIBGEN_H if you don't have libgen.h.
 127 #
 128 # Define NEEDS_LIBGEN if your libgen needs -lgen when linking
 129 #
 130 # Define NO_SYS_SELECT_H if you don't have sys/select.h.
 131 #
 132 # Define NO_SYMLINK_HEAD if you never want .git/HEAD to be a symbolic link.
 133 # Enable it on Windows.  By default, symrefs are still used.
 134 #
 135 # Define NO_SVN_TESTS if you want to skip time-consuming SVN interoperability
 136 # tests.  These tests take up a significant amount of the total test time
 137 # but are not needed unless you plan to talk to SVN repos.
 138 #
 139 # Define NO_FINK if you are building on Darwin/Mac OS X, have Fink
 140 # installed in /sw, but don't want GIT to link against any libraries
 141 # installed there.  If defined you may specify your own (or Fink's)
 142 # include directories and library directories by defining CFLAGS
 143 # and LDFLAGS appropriately.
 144 #
 145 # Define NO_DARWIN_PORTS if you are building on Darwin/Mac OS X,
 146 # have DarwinPorts installed in /opt/local, but don't want GIT to
 147 # link against any libraries installed there.  If defined you may
 148 # specify your own (or DarwinPort's) include directories and
 149 # library directories by defining CFLAGS and LDFLAGS appropriately.
 150 #
 151 # Define NO_APPLE_COMMON_CRYPTO if you are building on Darwin/Mac OS X
 152 # and do not want to use Apple's CommonCrypto library.  This allows you
 153 # to provide your own OpenSSL library, for example from MacPorts.
 154 #
 155 # Define BLK_SHA1 environment variable to make use of the bundled
 156 # optimized C SHA1 routine.
 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 #

 189 #
 190 # Define NEEDS_SSL_WITH_CRYPTO if you need -lssl when using -lcrypto (Darwin).
 191 #
 192 # Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
 193 #
 194 # Define NEEDS_LIBINTL_BEFORE_LIBICONV if you need libintl before libiconv.
 195 #
 196 # Define NO_INTPTR_T if you don't have intptr_t or uintptr_t.
 197 #
 198 # Define NO_UINTMAX_T if you don't have uintmax_t.
 199 #
 200 # Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
 201 # Patrick Mauritz).
 202 #
 203 # Define NEEDS_RESOLV if linking with -lnsl and/or -lsocket is not enough.
 204 # Notably on Solaris hstrerror resides in libresolv and on Solaris 7
 205 # inet_ntop and inet_pton additionally reside there.
 206 #
 207 # Define NO_MMAP if you want to avoid mmap.
 208 #
 209 # Define MMAP_PREVENTS_DELETE if a file that is currently mmapped cannot be
 210 # deleted or cannot be replaced using rename().
 211 #
 212 # Define NO_POLL_H if you don't have poll.h.
 213 #
 214 # Define NO_SYS_POLL_H if you don't have sys/poll.h.
 215 #
 216 # Define NO_POLL if you do not have or don't want to use poll().
 217 # This also implies NO_POLL_H and NO_SYS_POLL_H.
 218 #
 219 # Define NEEDS_SYS_PARAM_H if you need to include sys/param.h to compile,
 220 # *PLEASE* REPORT to git@vger.kernel.org if your platform needs this;
 221 # we want to know more about the issue.
 222 #
 223 # Define NO_PTHREADS if you do not have or do not want to use Pthreads.
 224 #
 225 # Define NO_PREAD if you have a problem with pread() system call (e.g.
 226 # cygwin1.dll before v1.5.22).
 227 #
 228 # Define NO_SETITIMER if you don't have setitimer()
 229 #
 230 # Define NO_STRUCT_ITIMERVAL if you don't have struct itimerval
 231 # This also implies NO_SETITIMER
 232 #
 233 # Define NO_FAST_WORKING_DIRECTORY if accessing objects in pack files is
 234 # generally faster on your platform than accessing the working directory.
 235 #
 236 # Define NO_TRUSTABLE_FILEMODE if your filesystem may claim to support
 237 # the executable mode bit, but doesn't really do so.
 238 #
 239 # Define CSPRNG_METHOD to "arc4random" if your system has arc4random and
 240 # arc4random_buf, "libbsd" if your system has those functions from libbsd,
 241 # "getrandom" if your system has getrandom, "getentropy" if your system has
 242 # getentropy, "rtlgenrandom" for RtlGenRandom (Windows only), or "openssl" if
 243 # you'd want to use the OpenSSL CSPRNG.  You may set multiple options with
 244 # spaces, in which case a suitable option will be chosen.  If unset or set to
 245 # anything else, defaults to using "/dev/urandom".
 246 #
 247 # Define NEEDS_MODE_TRANSLATION if your OS strays from the typical file type
 248 # bits in mode values (e.g. z/OS defines I_SFMT to 0xFF000000 as opposed to the
 249 # usual 0xF000).
 250 #
 251 # Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
 252 #
 253 # Define NO_UNIX_SOCKETS if your system does not offer unix sockets.
 254 #

 256 # sockaddr_storage.
 257 #
 258 # Define NO_ICONV if your libc does not properly support iconv.

 261 # (input buffer pointer) parameter is declared with type (const char **).
 262 #
 263 # Define ICONV_OMITS_BOM if your iconv implementation does not write a
 264 # byte-order mark (BOM) when writing UTF-16 or UTF-32 and always writes in
 265 # big-endian format.
 266 #
 267 # Define NO_DEFLATE_BOUND if your zlib does not have deflateBound.
 268 #
 269 # Define NO_NORETURN if using buggy versions of gcc 4.6+ and profile feedback,
 270 # as the compiler can crash (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49299)
 271 #
 272 # Define USE_NSEC below if you want git to care about sub-second file mtimes
 273 # and ctimes. Note that you need recent glibc (at least 2.2.4) for this. On
 274 # Linux, kernel 2.6.11 or newer is required for reliable sub-second file times
 275 # on file systems with exactly 1 ns or 1 s resolution. If you intend to use Git
 276 # on other file systems (e.g. CEPH, CIFS, NTFS, UDF), don't enable USE_NSEC. See
 277 # Documentation/technical/racy-git.txt for details.
 278 #
 279 # Define USE_ST_TIMESPEC if your "struct stat" uses "st_ctimespec" instead of
 280 # "st_ctim"
 281 #
 282 # Define NO_NSEC if your "struct stat" does not have "st_ctim.tv_nsec"
 283 # available.  This automatically turns USE_NSEC off.
 284 #
 285 # Define USE_STDEV below if you want git to care about the underlying device
 286 # change being considered an inode change from the update-index perspective.
 287 #
 288 # Define NO_ST_BLOCKS_IN_STRUCT_STAT if your platform does not have st_blocks
 289 # field that counts the on-disk footprint in 512-byte blocks.
 290 #
 291 # Define GNU_ROFF if your target system uses GNU groff.  This forces
 292 # apostrophes to be ASCII so that cut&pasting examples to the shell
 293 # will work.
 294 #
 295 # Define USE_ASCIIDOCTOR to use Asciidoctor instead of AsciiDoc to build the
 296 # documentation.
 297 #
 298 # Define ASCIIDOCTOR_EXTENSIONS_LAB to point to the location of the Asciidoctor
 299 # Extensions Lab if you have it available.
 300 #
 301 # Define PERL_PATH to the path of your Perl binary (usually /usr/bin/perl).
 302 #
 303 # Define NO_PERL if you do not want Perl scripts or libraries at all.
 304 #
 305 # Define NO_PERL_CPAN_FALLBACKS if you do not want to install bundled
 306 # copies of CPAN modules that serve as a fallback in case the modules
 307 # are not available on the system. This option is intended for
 308 # distributions that want to use their packaged versions of Perl
 309 # modules, instead of the fallbacks shipped with Git.
 310 #
 311 # Define NO_GITWEB if you do not want to build or install
 312 # 'gitweb'. Note that defining NO_PERL currently has the same effect
 313 # on not installing gitweb, but not on whether it's built in the
 314 # gitweb/ directory.
 315 #
 316 # Define PYTHON_PATH to the path of your Python binary (often /usr/bin/python
 317 # but /usr/bin/python2.7 or /usr/bin/python3 on some platforms).
 318 #
 319 # Define NO_PYTHON if you do not want Python scripts or libraries at all.
 320 #
 321 # Define NO_TCLTK if you do not want Tcl/Tk GUI.
 322 #
 323 # The TCL_PATH variable governs the location of the Tcl interpreter
 324 # used to optimize git-gui for your system.  Only used if NO_TCLTK
 325 # is not set.  Defaults to the bare 'tclsh'.
 326 #
 327 # The TCLTK_PATH variable governs the location of the Tcl/Tk interpreter.
 328 # If not set it defaults to the bare 'wish'. If it is set to the empty
 329 # string then NO_TCLTK will be forced (this is used by configure script).
 330 #
 331 # Define INTERNAL_QSORT to use Git's implementation of qsort(), which
 332 # is a simplified version of the merge sort used in glibc. This is
 333 # recommended if Git triggers O(n^2) behavior in your platform's qsort().
 334 #
 335 # Define HAVE_ISO_QSORT_S if your platform provides a qsort_s() that's
 336 # compatible with the one described in C11 Annex K.
 337 #
 338 # Define UNRELIABLE_FSTAT if your system's fstat does not return the same
 339 # information on a not yet closed file that lstat would return for the same
 340 # file after it was closed.
 341 #
 342 # Define OBJECT_CREATION_USES_RENAMES if your operating systems has problems
 343 # when hardlinking a file to another name and unlinking the original file right
 344 # away (some NTFS drivers seem to zero the contents in that scenario).
 345 #
 346 # Define INSTALL_SYMLINKS if you prefer to have everything that can be
 347 # symlinked between bin/ and libexec/ to use relative symlinks between
 348 # the two. This option overrides NO_CROSS_DIRECTORY_HARDLINKS and
 349 # NO_INSTALL_HARDLINKS which will also use symlinking by indirection
 350 # within the same directory in some cases, INSTALL_SYMLINKS will
 351 # always symlink to the final target directly.
 352 #
 353 # Define NO_CROSS_DIRECTORY_HARDLINKS if you plan to distribute the installed
 354 # programs as a tar, where bin/ and libexec/ might be on different file systems.
 355 #
 356 # Define NO_INSTALL_HARDLINKS if you prefer to use either symbolic links or
 357 # copies to install built-in git commands e.g. git-cat-file.
 358 #
 359 # Define SKIP_DASHED_BUILT_INS if you do not need the dashed versions of the
 360 # built-ins to be linked/copied at all.
 361 #
 362 # Define USE_NED_ALLOCATOR if you want to replace the platforms default
 363 # memory allocators with the nedmalloc allocator written by Niall Douglas.
 364 #
 365 # Define OVERRIDE_STRDUP to override the libc version of strdup(3).
 366 # This is necessary when using a custom allocator in order to avoid
 367 # crashes due to allocation and free working on different 'heaps'.
 368 # It's defined automatically if USE_NED_ALLOCATOR is set.
 369 #
 370 # Define NO_REGEX if your C library lacks regex support with REG_STARTEND
 371 # feature.
 372 #
 373 # Define HAVE_DEV_TTY if your system can open /dev/tty to interact with the
 374 # user.
 375 #

 377 # a filter to have gitweb.js minified.
 378 #
 379 # Define CSSMIN to point to a CSS minifier in order to generate a minified
 380 # version of gitweb.css
 381 #
 382 # Define DEFAULT_PAGER to a sensible pager command (defaults to "less") if
 383 # you want to use something different.  The value will be interpreted by the
 384 # shell at runtime when it is used.
 385 #
 386 # Define DEFAULT_EDITOR to a sensible editor command (defaults to "vi") if you
 387 # want to use something different.  The value will be interpreted by the shell
 388 # if necessary when it is used.  Examples:
 389 #
 390 #   DEFAULT_EDITOR='~/bin/vi',
 391 #   DEFAULT_EDITOR='$GIT_FALLBACK_EDITOR',
 392 #   DEFAULT_EDITOR='"C:\Program Files\Vim\gvim.exe" --nofork'
 393 #
 394 # Define COMPUTE_HEADER_DEPENDENCIES to "yes" if you want dependencies on
 395 # header files to be automatically computed, to avoid rebuilding objects when
 396 # an unrelated header file changes.  Define it to "no" to use the hard-coded
 397 # dependency rules.  The default is "auto", which means to use computed header
 398 # dependencies if your compiler is detected to support it.
 399 #
 400 # Define NATIVE_CRLF if your platform uses CRLF for line endings.
 401 #
 402 # Define GIT_USER_AGENT if you want to change how git identifies itself during
 403 # network interactions.  The default is "git/$(GIT_VERSION)".
 404 #
 405 # Define DEFAULT_HELP_FORMAT to "man", "info" or "html"
 406 # (defaults to "man") if you want to have a different default when
 407 # "git help" is called without a parameter specifying the format.
 408 #
 409 # Define GIT_TEST_INDEX_VERSION to 2, 3 or 4 to run the test suite
 410 # with a different indexfile format version.  If it isn't set the index
 411 # file format used is index-v[23].
 412 #
 413 # Define GIT_TEST_UTF8_LOCALE to preferred utf-8 locale for testing.
 414 # If it isn't set, fallback to $LC_ALL, $LANG or use the first utf-8
 415 # locale returned by "locale -a".
 416 #
 417 # Define HAVE_CLOCK_GETTIME if your platform has clock_gettime.
 418 #
 419 # Define HAVE_CLOCK_MONOTONIC if your platform has CLOCK_MONOTONIC.
 420 #
 421 # Define HAVE_SYNC_FILE_RANGE if your platform has sync_file_range.
 422 #
 423 # Define NEEDS_LIBRT if your platform requires linking with librt (glibc version
 424 # before 2.17) for clock_gettime and CLOCK_MONOTONIC.
 425 #
 426 # Define HAVE_BSD_SYSCTL if your platform has a BSD-compatible sysctl function.
 427 #
 428 # Define HAVE_GETDELIM if your system has the getdelim() function.
 429 #
 430 # Define FILENO_IS_A_MACRO if fileno() is a macro, not a real function.
 431 #
 432 # Define NEED_ACCESS_ROOT_HANDLER if access() under root may success for X_OK
 433 # even if execution permission isn't granted for any user.
 434 #
 435 # Define PAGER_ENV to a SP separated VAR=VAL pairs to define
 436 # default environment variables to be passed when a pager is spawned, e.g.
 437 #
 438 #    PAGER_ENV = LESS=FRX LV=-c
 439 #
 440 # to say "export LESS=FRX (and LV=-c) if the environment variable
 441 # LESS (and LV) is not set, respectively".
 442 #
 443 # Define TEST_SHELL_PATH if you want to use a shell besides SHELL_PATH for
 444 # running the test scripts (e.g., bash has better support for "set -x"
 445 # tracing).
 446 #
 447 # When cross-compiling, define HOST_CPU as the canonical name of the CPU on
 448 # which the built Git will run (for instance "x86_64").
 449 #
 450 # Define RUNTIME_PREFIX to configure Git to resolve its ancillary tooling and
 451 # support files relative to the location of the runtime binary, rather than
 452 # hard-coding them into the binary. Git installations built with RUNTIME_PREFIX
 453 # can be moved to arbitrary filesystem locations. RUNTIME_PREFIX also causes
 454 # Perl scripts to use a modified entry point header allowing them to resolve
 455 # support files at runtime.
 456 #
 457 # When using RUNTIME_PREFIX, define HAVE_BSD_KERN_PROC_SYSCTL if your platform
 458 # supports the KERN_PROC BSD sysctl function.
 459 #
 460 # When using RUNTIME_PREFIX, define PROCFS_EXECUTABLE_PATH if your platform
 461 # mounts a "procfs" filesystem capable of resolving the path of the current
 462 # executable. If defined, this must be the canonical path for the "procfs"
 463 # current executable path.
 464 #
 465 # When using RUNTIME_PREFIX, define HAVE_NS_GET_EXECUTABLE_PATH if your platform
 466 # supports calling _NSGetExecutablePath to retrieve the path of the running
 467 # executable.
 468 #
 469 # When using RUNTIME_PREFIX, define HAVE_WPGMPTR if your platform offers
 470 # the global variable _wpgmptr containing the absolute path of the current
 471 # executable (this is the case on Windows).
 472 #
 473 # INSTALL_STRIP can be set to "-s" to strip binaries during installation,
 474 # if your $(INSTALL) command supports the option.
 475 #
 476 # Define GENERATE_COMPILATION_DATABASE to "yes" to generate JSON compilation
 477 # database entries during compilation if your compiler supports it, using the
 478 # `-MJ` flag. The JSON entries will be placed in the `compile_commands/`
 479 # directory, and the JSON compilation database 'compile_commands.json' will be
 480 # created at the root of the repository.
 481 #
 482 # If your platform supports a built-in fsmonitor backend, set
 483 # FSMONITOR_DAEMON_BACKEND to the "<name>" of the corresponding
 484 # `compat/fsmonitor/fsm-listen-<name>.c` and
 485 # `compat/fsmonitor/fsm-health-<name>.c` files
 486 # that implement the `fsm_listen__*()` and `fsm_health__*()` routines.
 487 #
 488 # If your platform has OS-specific ways to tell if a repo is incompatible with
 489 # fsmonitor (whether the hook or IPC daemon version), set FSMONITOR_OS_SETTINGS
 490 # to the "<name>" of the corresponding `compat/fsmonitor/fsm-settings-<name>.c`
 491 # that implements the `fsm_os_settings__*()` routines.
 492 #
 493 # Define DEVELOPER to enable more compiler warnings. Compiler version
 494 # and family are auto detected, but could be overridden by defining
 495 # COMPILER_FEATURES (see config.mak.dev). You can still set
 496 # CFLAGS="..." in combination with DEVELOPER enables, whether that's
 497 # for tweaking something unrelated (e.g. optimization level), or for
 498 # selectively overriding something DEVELOPER or one of the DEVOPTS
 499 # (see just below) brings in.
 500 #
 501 # When DEVELOPER is set, DEVOPTS can be used to control compiler
 502 # options.  This variable contains keywords separated by
 503 # whitespace. The following keywords are recognized:
 504 #
 505 #    no-error:
 506 #
 507 #        suppresses the -Werror that implicitly comes with
 508 #        DEVELOPER=1. Useful for getting the full set of errors
 509 #        without immediately dying, or for logging them.
 510 #
 511 #    extra-all:
 512 #
 513 #        The DEVELOPER mode enables -Wextra with a few exceptions. By
 514 #        setting this flag the exceptions are removed, and all of
 515 #        -Wextra is used.
 516 #
 517 #    no-pedantic:
 518 #
 519 #        Disable -pedantic compilation.

2252 ### Target-specific flags and dependencies
2253
2254 # The generic compilation pattern rule and automatically
2255 # computed header dependencies (falling back to a dependency on
2256 # LIB_H) are enough to describe how most targets should be built,
2257 # but some targets are special enough to need something a little
2258 # different.
2259 #
2260 # - When a source file "foo.c" #includes a generated header file,
2261 #   we need to list that dependency for the "foo.o" target.
2262 #
2263 #   We also list it from other targets that are built from foo.c
2264 #   like "foo.sp" and "foo.s", even though that is easy to forget
2265 #   to do because the generated header is already present around
2266 #   after a regular build attempt.
2267 #
2268 # - Some code depends on configuration kept in makefile
2269 #   variables. The target-specific variable EXTRA_CPPFLAGS can
2270 #   be used to convey that information to the C preprocessor
2271 #   using -D options.
2272 #
2273 #   The "foo.o" target should have a corresponding dependency on
2274 #   a file that changes when the value of the makefile variable
2275 #   changes.  For example, targets making use of the
2276 #   $(GIT_VERSION) variable depend on GIT-VERSION-FILE.
2277 #
2278 #   Technically the ".sp" and ".s" targets do not need this
2279 #   dependency because they are force-built, but they get the
2280 #   same dependency for consistency. This way, you do not have to
2281 #   know how each target is implemented. And it means the
2282 #   dependencies here will not need to change if the force-build
2283 #   details change some day.

3624 #
3625 # Building fuzz targets generally requires a special set of compiler flags that
3626 # are not necessarily appropriate for general builds, and that vary greatly
3627 # depending on the compiler version used.

3629 # An example command to build against libFuzzer from LLVM 11.0.0:
3630 #
3631 # make CC=clang CXX=clang++ \
3632 #      CFLAGS="-fsanitize=fuzzer-no-link,address" \
3633 #      LIB_FUZZING_ENGINE="-fsanitize=fuzzer" \
