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.

 183 #
 184 # Define OPENSSL_SHA256 to use the SHA-256 routines in OpenSSL.
 185 #
 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 NEEDS_MODE_TRANSLATION if your OS strays from the typical file type
 238 # bits in mode values (e.g. z/OS defines I_SFMT to 0xFF000000 as opposed to the
 239 # usual 0xF000).
 240 #
 241 # Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
 242 #
 243 # Define NO_UNIX_SOCKETS if your system does not offer unix sockets.
 244 #
 245 # Define NO_SOCKADDR_STORAGE if your platform does not have struct
 246 # sockaddr_storage.
 247 #
 248 # Define NO_ICONV if your libc does not properly support iconv.
 249 #
 250 # Define OLD_ICONV if your library has an old iconv(), where the second
 251 # (input buffer pointer) parameter is declared with type (const char **).
 252 #
 253 # Define ICONV_OMITS_BOM if your iconv implementation does not write a
 254 # byte-order mark (BOM) when writing UTF-16 or UTF-32 and always writes in
 255 # big-endian format.
 256 #
 257 # Define NO_DEFLATE_BOUND if your zlib does not have deflateBound.
 258 #
 259 # Define NO_NORETURN if using buggy versions of gcc 4.6+ and profile feedback,
 260 # as the compiler can crash (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49299)
 261 #
 262 # Define USE_NSEC below if you want git to care about sub-second file mtimes
 263 # and ctimes. Note that you need recent glibc (at least 2.2.4) for this. On
 264 # Linux, kernel 2.6.11 or newer is required for reliable sub-second file times
 265 # on file systems with exactly 1 ns or 1 s resolution. If you intend to use Git
 266 # on other file systems (e.g. CEPH, CIFS, NTFS, UDF), don't enable USE_NSEC. See
 267 # Documentation/technical/racy-git.txt for details.
 268 #
 269 # Define USE_ST_TIMESPEC if your "struct stat" uses "st_ctimespec" instead of
 270 # "st_ctim"
 271 #
 272 # Define NO_NSEC if your "struct stat" does not have "st_ctim.tv_nsec"
 273 # available.  This automatically turns USE_NSEC off.
 274 #
 275 # Define USE_STDEV below if you want git to care about the underlying device
 276 # change being considered an inode change from the update-index perspective.
 277 #
 278 # Define NO_ST_BLOCKS_IN_STRUCT_STAT if your platform does not have st_blocks
 279 # field that counts the on-disk footprint in 512-byte blocks.
 280 #
 281 # Define GNU_ROFF if your target system uses GNU groff.  This forces
 282 # apostrophes to be ASCII so that cut&pasting examples to the shell
 283 # will work.
 284 #
 285 # Define USE_ASCIIDOCTOR to use Asciidoctor instead of AsciiDoc to build the
 286 # documentation.
 287 #
 288 # Define ASCIIDOCTOR_EXTENSIONS_LAB to point to the location of the Asciidoctor
 289 # Extensions Lab if you have it available.
 290 #
 291 # Define PERL_PATH to the path of your Perl binary (usually /usr/bin/perl).
 292 #
 293 # Define NO_PERL if you do not want Perl scripts or libraries at all.
 294 #
 295 # Define NO_PERL_CPAN_FALLBACKS if you do not want to install bundled
 296 # copies of CPAN modules that serve as a fallback in case the modules
 297 # are not available on the system. This option is intended for
 298 # distributions that want to use their packaged versions of Perl
 299 # modules, instead of the fallbacks shipped with Git.
 300 #
 301 # Define PYTHON_PATH to the path of your Python binary (often /usr/bin/python
 302 # but /usr/bin/python2.7 or /usr/bin/python3 on some platforms).
 303 #
 304 # Define NO_PYTHON if you do not want Python scripts or libraries at all.
 305 #
 306 # Define NO_TCLTK if you do not want Tcl/Tk GUI.
 307 #
 308 # Define SANE_TEXT_GREP to "-a" if you use recent versions of GNU grep
 309 # and egrep that are pickier when their input contains non-ASCII data.
 310 #
 311 # The TCL_PATH variable governs the location of the Tcl interpreter
 312 # used to optimize git-gui for your system.  Only used if NO_TCLTK
 313 # is not set.  Defaults to the bare 'tclsh'.
 314 #
 315 # The TCLTK_PATH variable governs the location of the Tcl/Tk interpreter.
 316 # If not set it defaults to the bare 'wish'. If it is set to the empty
 317 # string then NO_TCLTK will be forced (this is used by configure script).
 318 #
 319 # Define INTERNAL_QSORT to use Git's implementation of qsort(), which
 320 # is a simplified version of the merge sort used in glibc. This is
 321 # recommended if Git triggers O(n^2) behavior in your platform's qsort().
 322 #
 323 # Define HAVE_ISO_QSORT_S if your platform provides a qsort_s() that's
 324 # compatible with the one described in C11 Annex K.
 325 #
 326 # Define UNRELIABLE_FSTAT if your system's fstat does not return the same
 327 # information on a not yet closed file that lstat would return for the same
 328 # file after it was closed.
 329 #
 330 # Define OBJECT_CREATION_USES_RENAMES if your operating systems has problems
 331 # when hardlinking a file to another name and unlinking the original file right
 332 # away (some NTFS drivers seem to zero the contents in that scenario).
 333 #
 334 # Define INSTALL_SYMLINKS if you prefer to have everything that can be
 335 # symlinked between bin/ and libexec/ to use relative symlinks between
 336 # the two. This option overrides NO_CROSS_DIRECTORY_HARDLINKS and
 337 # NO_INSTALL_HARDLINKS which will also use symlinking by indirection
 338 # within the same directory in some cases, INSTALL_SYMLINKS will
 339 # always symlink to the final target directly.
 340 #
 341 # Define NO_CROSS_DIRECTORY_HARDLINKS if you plan to distribute the installed
 342 # programs as a tar, where bin/ and libexec/ might be on different file systems.
 343 #
 344 # Define NO_INSTALL_HARDLINKS if you prefer to use either symbolic links or
 345 # copies to install built-in git commands e.g. git-cat-file.
 346 #
 347 # Define SKIP_DASHED_BUILT_INS if you do not need the dashed versions of the
 348 # built-ins to be linked/copied at all.
 349 #
 350 # Define USE_NED_ALLOCATOR if you want to replace the platforms default
 351 # memory allocators with the nedmalloc allocator written by Niall Douglas.
 352 #
 353 # Define OVERRIDE_STRDUP to override the libc version of strdup(3).
 354 # This is necessary when using a custom allocator in order to avoid
 355 # crashes due to allocation and free working on different 'heaps'.
 356 # It's defined automatically if USE_NED_ALLOCATOR is set.
 357 #
 358 # Define NO_REGEX if your C library lacks regex support with REG_STARTEND

 366 #
 367 # Define CSSMIN to point to a CSS minifier in order to generate a minified
 368 # version of gitweb.css
 369 #
 370 # Define DEFAULT_PAGER to a sensible pager command (defaults to "less") if
 371 # you want to use something different.  The value will be interpreted by the
 372 # shell at runtime when it is used.
 373 #
 374 # Define DEFAULT_EDITOR to a sensible editor command (defaults to "vi") if you
 375 # want to use something different.  The value will be interpreted by the shell
 376 # if necessary when it is used.  Examples:
 377 #
 378 #   DEFAULT_EDITOR='~/bin/vi',
 379 #   DEFAULT_EDITOR='$GIT_FALLBACK_EDITOR',
 380 #   DEFAULT_EDITOR='"C:\Program Files\Vim\gvim.exe" --nofork'
 381 #
 382 # Define COMPUTE_HEADER_DEPENDENCIES to "yes" if you want dependencies on
 383 # header files to be automatically computed, to avoid rebuilding objects when
 384 # an unrelated header file changes.  Define it to "no" to use the hard-coded
 385 # dependency rules.  The default is "auto", which means to use computed header
 386 # dependencies if your compiler is detected to support it.
 387 #
 388 # Define NATIVE_CRLF if your platform uses CRLF for line endings.
 389 #
 390 # Define GIT_USER_AGENT if you want to change how git identifies itself during
 391 # network interactions.  The default is "git/$(GIT_VERSION)".
 392 #
 393 # Define DEFAULT_HELP_FORMAT to "man", "info" or "html"
 394 # (defaults to "man") if you want to have a different default when
 395 # "git help" is called without a parameter specifying the format.
 396 #
 397 # Define GIT_TEST_INDEX_VERSION to 2, 3 or 4 to run the test suite
 398 # with a different indexfile format version.  If it isn't set the index
 399 # file format used is index-v[23].
 400 #
 401 # Define GIT_TEST_UTF8_LOCALE to preferred utf-8 locale for testing.
 402 # If it isn't set, fallback to $LC_ALL, $LANG or use the first utf-8
 403 # locale returned by "locale -a".
 404 #
 405 # Define HAVE_CLOCK_GETTIME if your platform has clock_gettime.
 406 #
 407 # Define HAVE_CLOCK_MONOTONIC if your platform has CLOCK_MONOTONIC.
 408 #
 409 # Define NEEDS_LIBRT if your platform requires linking with librt (glibc version
 410 # before 2.17) for clock_gettime and CLOCK_MONOTONIC.
 411 #
 412 # Define USE_PARENS_AROUND_GETTEXT_N to "yes" if your compiler happily
 413 # compiles the following initialization:
 414 #
 415 #   static const char s[] = ("FOO");
 416 #
 417 # and define it to "no" if you need to remove the parentheses () around the
 418 # constant.  The default is "auto", which means to use parentheses if your
 419 # compiler is detected to support it.
 420 #
 421 # Define HAVE_BSD_SYSCTL if your platform has a BSD-compatible sysctl function.
 422 #
 423 # Define HAVE_GETDELIM if your system has the getdelim() function.
 424 #
 425 # Define FILENO_IS_A_MACRO if fileno() is a macro, not a real function.
 426 #
 427 # Define NEED_ACCESS_ROOT_HANDLER if access() under root may success for X_OK
 428 # even if execution permission isn't granted for any user.
 429 #
 430 # Define PAGER_ENV to a SP separated VAR=VAL pairs to define
 431 # default environment variables to be passed when a pager is spawned, e.g.
 432 #
 433 #    PAGER_ENV = LESS=FRX LV=-c
 434 #
 435 # to say "export LESS=FRX (and LV=-c) if the environment variable
 436 # LESS (and LV) is not set, respectively".
 437 #
 438 # Define TEST_SHELL_PATH if you want to use a shell besides SHELL_PATH for
 439 # running the test scripts (e.g., bash has better support for "set -x"
 440 # tracing).
 441 #
 442 # When cross-compiling, define HOST_CPU as the canonical name of the CPU on
 443 # which the built Git will run (for instance "x86_64").
 444 #
 445 # Define RUNTIME_PREFIX to configure Git to resolve its ancillary tooling and
 446 # support files relative to the location of the runtime binary, rather than
 447 # hard-coding them into the binary. Git installations built with RUNTIME_PREFIX
 448 # can be moved to arbitrary filesystem locations. RUNTIME_PREFIX also causes
 449 # Perl scripts to use a modified entry point header allowing them to resolve
 450 # support files at runtime.
 451 #
 452 # When using RUNTIME_PREFIX, define HAVE_BSD_KERN_PROC_SYSCTL if your platform
 453 # supports the KERN_PROC BSD sysctl function.
 454 #
 455 # When using RUNTIME_PREFIX, define PROCFS_EXECUTABLE_PATH if your platform
 456 # mounts a "procfs" filesystem capable of resolving the path of the current
 457 # executable. If defined, this must be the canonical path for the "procfs"
 458 # current executable path.
 459 #
 460 # When using RUNTIME_PREFIX, define HAVE_NS_GET_EXECUTABLE_PATH if your platform
 461 # supports calling _NSGetExecutablePath to retrieve the path of the running
 462 # executable.
 463 #
 464 # When using RUNTIME_PREFIX, define HAVE_WPGMPTR if your platform offers
 465 # the global variable _wpgmptr containing the absolute path of the current
 466 # executable (this is the case on Windows).

 468 # Define GENERATE_COMPILATION_DATABASE to "yes" to generate JSON compilation
 469 # database entries during compilation if your compiler supports it, using the
 470 # `-MJ` flag. The JSON entries will be placed in the `compile_commands/`
 471 # directory, and the JSON compilation database 'compile_commands.json' will be
 472 # created at the root of the repository.
 473 #
 474 # Define DEVELOPER to enable more compiler warnings. Compiler version
 475 # and family are auto detected, but could be overridden by defining
 476 # COMPILER_FEATURES (see config.mak.dev). You can still set
 477 # CFLAGS="..." in combination with DEVELOPER enables, whether that's
 478 # for tweaking something unrelated (e.g. optimization level), or for
 479 # selectively overriding something DEVELOPER or one of the DEVOPTS
 480 # (see just below) brings in.
 481 #
 482 # When DEVELOPER is set, DEVOPTS can be used to control compiler
 483 # options.  This variable contains keywords separated by
 484 # whitespace. The following keywords are recognized:
 485 #
 486 #    no-error:
 487 #
 488 #        suppresses the -Werror that implicitly comes with
 489 #        DEVELOPER=1. Useful for getting the full set of errors
 490 #        without immediately dying, or for logging them.
 491 #
 492 #    extra-all:
 493 #
 494 #        The DEVELOPER mode enables -Wextra with a few exceptions. By
 495 #        setting this flag the exceptions are removed, and all of
 496 #        -Wextra is used.
 497 #
 498 #    pedantic:
 499 #
 500 #        Enable -pedantic compilation. This also disables
 501 #        USE_PARENS_AROUND_GETTEXT_N to produce only relevant warnings.

2182 ### Target-specific flags and dependencies
2183
2184 # The generic compilation pattern rule and automatically
2185 # computed header dependencies (falling back to a dependency on
2186 # LIB_H) are enough to describe how most targets should be built,
2187 # but some targets are special enough to need something a little
2188 # different.
2189 #
2190 # - When a source file "foo.c" #includes a generated header file,
2191 #   we need to list that dependency for the "foo.o" target.
2192 #
2193 #   We also list it from other targets that are built from foo.c
2194 #   like "foo.sp" and "foo.s", even though that is easy to forget
2195 #   to do because the generated header is already present around
2196 #   after a regular build attempt.
2197 #
2198 # - Some code depends on configuration kept in makefile
2199 #   variables. The target-specific variable EXTRA_CPPFLAGS can
2200 #   be used to convey that information to the C preprocessor
2201 #   using -D options.
2202 #
2203 #   The "foo.o" target should have a corresponding dependency on
2204 #   a file that changes when the value of the makefile variable
2205 #   changes.  For example, targets making use of the
2206 #   $(GIT_VERSION) variable depend on GIT-VERSION-FILE.
2207 #
2208 #   Technically the ".sp" and ".s" targets do not need this
2209 #   dependency because they are force-built, but they get the
2210 #   same dependency for consistency. This way, you do not have to
2211 #   know how each target is implemented. And it means the
2212 #   dependencies here will not need to change if the force-build
2213 #   details change some day.

3380 #
3381 # Building fuzz targets generally requires a special set of compiler flags that
3382 # are not necessarily appropriate for general builds, and that vary greatly
3383 # depending on the compiler version used.
3384 #
3385 # An example command to build against libFuzzer from LLVM 11.0.0:
3386 #
3387 # make CC=clang CXX=clang++ \
3388 #      CFLAGS="-fsanitize=fuzzer-no-link,address" \
3389 #      LIB_FUZZING_ENGINE="-fsanitize=fuzzer" \
