Makefile

   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 # == Makefile defines ==
   8 #
   9 # These defines change the behavior of the Makefile itself, but have
  10 # no impact on what it builds:
  11 #
  12 # Define V=1 to have a more verbose compile.
  13 #
  14 # == Portability and optional library defines ==
  15 #
  16 # These defines indicate what Git can expect from the OS, what
  17 # libraries are available etc. Much of this is auto-detected in
  18 # config.mak.uname, or in configure.ac when using the optional "make
  19 # configure && ./configure" (see INSTALL).
  20 #
  21 # Define SHELL_PATH to a POSIX shell if your /bin/sh is broken.
  22 #
  23 # Define SANE_TOOL_PATH to a colon-separated list of paths to prepend
  24 # to PATH if your tools in /usr/bin are broken.
  25 #
  26 # Define SOCKLEN_T to a suitable type (such as 'size_t') if your
  27 # system headers do not define a socklen_t type.
  28 #
  29 # Define INLINE to a suitable substitute (such as '__inline' or '') if git
  30 # fails to compile with errors about undefined inline functions or similar.
  31 #
  32 # Define SNPRINTF_RETURNS_BOGUS if you are on a system which snprintf()
  33 # or vsnprintf() return -1 instead of number of characters which would
  34 # have been written to the final string if enough space had been available.
  35 #
  36 # Define FREAD_READS_DIRECTORIES if you are on a system which succeeds
  37 # when attempting to read from an fopen'ed directory (or even to fopen
  38 # it at all).
  39 #
  40 # Define OPEN_RETURNS_EINTR if your open() system call may return EINTR
  41 # when a signal is received (as opposed to restarting).
  42 #
  43 # Define NO_OPENSSL environment variable if you do not have OpenSSL.
  44 #
  45 # Define HAVE_ALLOCA_H if you have working alloca(3) defined in that header.
  46 #
  47 # Define HAVE_PATHS_H if you have paths.h and want to use the default PATH
  48 # it specifies.
  49 #
  50 # Define NO_D_TYPE_IN_DIRENT if your platform defines DT_UNKNOWN but lacks
  51 # d_type in struct dirent (Cygwin 1.5, fixed in Cygwin 1.7).
  52 #
  53 # Define HAVE_STRINGS_H if you have strings.h and need it for strcasecmp.

  60 #
  61 # Define NO_STRLCPY if you don't have strlcpy.
  62 #
  63 # Define NO_STRTOUMAX if you don't have both strtoimax and strtoumax in the
  64 # C library. If your compiler also does not support long long or does not have
  65 # strtoull, define NO_STRTOULL.
  66 #
  67 # Define NO_SETENV if you don't have setenv in the C library.
  68 #
  69 # Define NO_UNSETENV if you don't have unsetenv in the C library.
  70 #
  71 # Define NO_MKDTEMP if you don't have mkdtemp in the C library.
  72 #
  73 # Define MKDIR_WO_TRAILING_SLASH if your mkdir() can't deal with trailing slash.
  74 #

  83 #
  84 # Define NO_SYMLINK_HEAD if you never want .git/HEAD to be a symbolic link.
  85 # Enable it on Windows.  By default, symrefs are still used.
  86 #
  87 # Define NO_SVN_TESTS if you want to skip time-consuming SVN interoperability
  88 # tests.  These tests take up a significant amount of the total test time
  89 # but are not needed unless you plan to talk to SVN repos.
  90 #
  91 # Define NO_FINK if you are building on Darwin/Mac OS X, have Fink
  92 # installed in /sw, but don't want GIT to link against any libraries
  93 # installed there.  If defined you may specify your own (or Fink's)
  94 # include directories and library directories by defining CFLAGS
  95 # and LDFLAGS appropriately.
  96 #
  97 # Define NO_DARWIN_PORTS if you are building on Darwin/Mac OS X,
  98 # have DarwinPorts installed in /opt/local, but don't want GIT to
  99 # link against any libraries installed there.  If defined you may
 100 # specify your own (or DarwinPort's) include directories and
 101 # library directories by defining CFLAGS and LDFLAGS appropriately.
 102 #
 103 # Define NO_APPLE_COMMON_CRYPTO if you are building on Darwin/Mac OS X
 104 # and do not want to use Apple's CommonCrypto library.  This allows you
 105 # to provide your own OpenSSL library, for example from MacPorts.
 106 #
 107 # Define NEEDS_CRYPTO_WITH_SSL if you need -lcrypto when using -lssl (Darwin).
 108 #
 109 # Define NEEDS_SSL_WITH_CRYPTO if you need -lssl when using -lcrypto (Darwin).
 110 #
 111 # Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).

 117 # Define NO_UINTMAX_T if you don't have uintmax_t.
 118 #
 119 # Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
 120 # Patrick Mauritz).
 121 #
 122 # Define NEEDS_RESOLV if linking with -lnsl and/or -lsocket is not enough.
 123 # Notably on Solaris hstrerror resides in libresolv and on Solaris 7
 124 # inet_ntop and inet_pton additionally reside there.
 125 #
 126 # Define NO_MMAP if you want to avoid mmap.
 127 #
 128 # Define MMAP_PREVENTS_DELETE if a file that is currently mmapped cannot be
 129 # deleted or cannot be replaced using rename().
 130 #
 131 # Define NO_POLL_H if you don't have poll.h.
 132 #
 133 # Define NO_SYS_POLL_H if you don't have sys/poll.h.
 134 #
 135 # Define NO_POLL if you do not have or don't want to use poll().
 136 # This also implies NO_POLL_H and NO_SYS_POLL_H.
 137 #
 138 # Define NEEDS_SYS_PARAM_H if you need to include sys/param.h to compile,
 139 # *PLEASE* REPORT to git@vger.kernel.org if your platform needs this;
 140 # we want to know more about the issue.
 141 #
 142 # Define NO_PTHREADS if you do not have or do not want to use Pthreads.
 143 #
 144 # Define NO_PREAD if you have a problem with pread() system call (e.g.

 146 #
 147 # Define NO_SETITIMER if you don't have setitimer()
 148 #
 149 # Define NO_STRUCT_ITIMERVAL if you don't have struct itimerval
 150 # This also implies NO_SETITIMER
 151 #
 152 # Define NO_FAST_WORKING_DIRECTORY if accessing objects in pack files is
 153 # generally faster on your platform than accessing the working directory.
 154 #
 155 # Define NO_TRUSTABLE_FILEMODE if your filesystem may claim to support
 156 # the executable mode bit, but doesn't really do so.
 157 #
 158 # Define CSPRNG_METHOD to "arc4random" if your system has arc4random and
 159 # arc4random_buf, "libbsd" if your system has those functions from libbsd,
 160 # "getrandom" if your system has getrandom, "getentropy" if your system has
 161 # getentropy, "rtlgenrandom" for RtlGenRandom (Windows only), or "openssl" if
 162 # you'd want to use the OpenSSL CSPRNG.  You may set multiple options with
 163 # spaces, in which case a suitable option will be chosen.  If unset or set to
 164 # anything else, defaults to using "/dev/urandom".
 165 #
 166 # Define NEEDS_MODE_TRANSLATION if your OS strays from the typical file type
 167 # bits in mode values (e.g. z/OS defines I_SFMT to 0xFF000000 as opposed to the
 168 # usual 0xF000).
 169 #
 170 # Define NO_IPV6 if you lack IPv6 support and getaddrinfo().

 176 #
 177 # Define NO_ICONV if your libc does not properly support iconv.

 180 # (input buffer pointer) parameter is declared with type (const char **).
 181 #
 182 # Define ICONV_OMITS_BOM if your iconv implementation does not write a
 183 # byte-order mark (BOM) when writing UTF-16 or UTF-32 and always writes in
 184 # big-endian format.
 185 #
 186 # Define NO_DEFLATE_BOUND if your zlib does not have deflateBound. Define
 187 # ZLIB_NG if you want to use zlib-ng instead of zlib.
 188 #
 189 # Define NO_NORETURN if using buggy versions of gcc 4.6+ and profile feedback,
 190 # as the compiler can crash (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=49299)
 191 #
 192 # Define USE_NSEC below if you want git to care about sub-second file mtimes
 193 # and ctimes. Note that you need recent glibc (at least 2.2.4) for this. On
 194 # Linux, kernel 2.6.11 or newer is required for reliable sub-second file times
 195 # on file systems with exactly 1 ns or 1 s resolution. If you intend to use Git
 196 # on other file systems (e.g. CEPH, CIFS, NTFS, UDF), don't enable USE_NSEC. See
 197 # Documentation/technical/racy-git.adoc for details.
 198 #
 199 # Define USE_ST_TIMESPEC if your "struct stat" uses "st_ctimespec" instead of
 200 # "st_ctim"
 201 #
 202 # Define NO_NSEC if your "struct stat" does not have "st_ctim.tv_nsec"
 203 # available.  This automatically turns USE_NSEC off.
 204 #
 205 # Define USE_STDEV below if you want git to care about the underlying device
 206 # change being considered an inode change from the update-index perspective.
 207 #
 208 # Define NO_ST_BLOCKS_IN_STRUCT_STAT if your platform does not have st_blocks
 209 # field that counts the on-disk footprint in 512-byte blocks.

 211 # Define USE_ASCIIDOCTOR to use Asciidoctor instead of AsciiDoc to build the
 212 # documentation.
 213 #
 214 # Define ASCIIDOCTOR_EXTENSIONS_LAB to point to the location of the Asciidoctor
 215 # Extensions Lab if you have it available.
 216 #
 217 # Define PERL_PATH to the path of your Perl binary (usually /usr/bin/perl).
 218 #
 219 # Define NO_PERL if you do not want Perl scripts or libraries at all.
 220 #
 221 # Define NO_PERL_CPAN_FALLBACKS if you do not want to install bundled
 222 # copies of CPAN modules that serve as a fallback in case the modules
 223 # are not available on the system. This option is intended for
 224 # distributions that want to use their packaged versions of Perl
 225 # modules, instead of the fallbacks shipped with Git.
 226 #
 227 # Define NO_GITWEB if you do not want to build or install
 228 # 'gitweb'. Note that defining NO_PERL currently has the same effect
 229 # on not installing gitweb, but not on whether it's built in the
 230 # gitweb/ directory.
 231 #
 232 # Define PYTHON_PATH to the path of your Python binary (often /usr/bin/python
 233 # but /usr/bin/python2.7 or /usr/bin/python3 on some platforms).
 234 #
 235 # Define NO_PYTHON if you do not want Python scripts or libraries at all.
 236 #
 237 # Define NO_TCLTK if you do not want Tcl/Tk GUI.
 238 #
 239 # The TCL_PATH variable governs the location of the Tcl interpreter
 240 # used to optimize git-gui for your system.  Only used if NO_TCLTK
 241 # is not set.  Defaults to the bare 'tclsh'.
 242 #
 243 # The TCLTK_PATH variable governs the location of the Tcl/Tk interpreter.
 244 # If not set it defaults to the bare 'wish'. If it is set to the empty
 245 # string then NO_TCLTK will be forced (this is used by configure script).
 246 #
 247 # Define INTERNAL_QSORT to use Git's implementation of qsort(), which
 248 # is a simplified version of the merge sort used in glibc. This is
 249 # recommended if Git triggers O(n^2) behavior in your platform's qsort().
 250 #
 251 # Define HAVE_ISO_QSORT_S if your platform provides a qsort_s() that's
 252 # compatible with the one described in C11 Annex K.
 253 #
 254 # Define UNRELIABLE_FSTAT if your system's fstat does not return the same
 255 # information on a not yet closed file that lstat would return for the same
 256 # file after it was closed.
 257 #
 258 # Define OBJECT_CREATION_USES_RENAMES if your operating systems has problems
 259 # when hardlinking a file to another name and unlinking the original file right
 260 # away (some NTFS drivers seem to zero the contents in that scenario).
 261 #
 262 # Define INSTALL_SYMLINKS if you prefer to have everything that can be
 263 # symlinked between bin/ and libexec/ to use relative symlinks between
 264 # the two. This option overrides NO_CROSS_DIRECTORY_HARDLINKS and
 265 # NO_INSTALL_HARDLINKS which will also use symlinking by indirection
 266 # within the same directory in some cases, INSTALL_SYMLINKS will
 267 # always symlink to the final target directly.
 268 #
 269 # Define NO_CROSS_DIRECTORY_HARDLINKS if you plan to distribute the installed
 270 # programs as a tar, where bin/ and libexec/ might be on different file systems.
 271 #
 272 # Define NO_INSTALL_HARDLINKS if you prefer to use either symbolic links or
 273 # copies to install built-in git commands e.g. git-cat-file.
 274 #
 275 # Define SKIP_DASHED_BUILT_INS if you do not need the dashed versions of the
 276 # built-ins to be linked/copied at all.
 277 #
 278 # Define USE_NED_ALLOCATOR if you want to replace the platforms default
 279 # memory allocators with the nedmalloc allocator written by Niall Douglas.
 280 #
 281 # Define OVERRIDE_STRDUP to override the libc version of strdup(3).
 282 # This is necessary when using a custom allocator in order to avoid
 283 # crashes due to allocation and free working on different 'heaps'.
 284 # It's defined automatically if USE_NED_ALLOCATOR is set.
 285 #
 286 # Define NO_REGEX if your C library lacks regex support with REG_STARTEND
 287 # feature.
 288 #
 289 # Define USE_ENHANCED_BASIC_REGULAR_EXPRESSIONS if your C library provides

 291 # regular expressions.
 292 #
 293 # Define HAVE_DEV_TTY if your system can open /dev/tty to interact with the
 294 # user.
 295 #
 296 # Define JSMIN to point to JavaScript minifier that functions as
 297 # a filter to have gitweb.js minified.
 298 #
 299 # Define CSSMIN to point to a CSS minifier in order to generate a minified
 300 # version of gitweb.css
 301 #
 302 # Define DEFAULT_PAGER to a sensible pager command (defaults to "less") if
 303 # you want to use something different.  The value will be interpreted by the
 304 # shell at runtime when it is used.
 305 #
 306 # Define DEFAULT_EDITOR to a sensible editor command (defaults to "vi") if you
 307 # want to use something different.  The value will be interpreted by the shell
 308 # if necessary when it is used.  Examples:
 309 #
 310 #   DEFAULT_EDITOR='~/bin/vi',
 311 #   DEFAULT_EDITOR='$GIT_FALLBACK_EDITOR',
 312 #   DEFAULT_EDITOR='"C:\Program Files\Vim\gvim.exe" --nofork'
 313 #
 314 # Define COMPUTE_HEADER_DEPENDENCIES to "yes" if you want dependencies on
 315 # header files to be automatically computed, to avoid rebuilding objects when
 316 # an unrelated header file changes.  Define it to "no" to use the hard-coded
 317 # dependency rules.  The default is "auto", which means to use computed header
 318 # dependencies if your compiler is detected to support it.
 319 #
 320 # Define NATIVE_CRLF if your platform uses CRLF for line endings.
 321 #
 322 # Define GIT_USER_AGENT if you want to change how git identifies itself during
 323 # network interactions.  The default is "git/$(GIT_VERSION)".
 324 #
 325 # Define DEFAULT_HELP_FORMAT to "man", "info" or "html"
 326 # (defaults to "man") if you want to have a different default when
 327 # "git help" is called without a parameter specifying the format.
 328 #
 329 # Define GIT_TEST_INDEX_VERSION to 2, 3 or 4 to run the test suite
 330 # with a different indexfile format version.  If it isn't set the index
 331 # file format used is index-v[23].
 332 #
 333 # Define GIT_TEST_UTF8_LOCALE to preferred utf-8 locale for testing.
 334 # If it isn't set, fallback to $LC_ALL, $LANG or use the first utf-8
 335 # locale returned by "locale -a".
 336 #
 337 # Define HAVE_CLOCK_GETTIME if your platform has clock_gettime.
 338 #
 339 # Define HAVE_CLOCK_MONOTONIC if your platform has CLOCK_MONOTONIC.
 340 #
 341 # Define HAVE_SYNC_FILE_RANGE if your platform has sync_file_range.

 350 # even if execution permission isn't granted for any user.
 351 #
 352 # Define PAGER_ENV to a SP separated VAR=VAL pairs to define
 353 # default environment variables to be passed when a pager is spawned, e.g.
 354 #
 355 #    PAGER_ENV = LESS=FRX LV=-c
 356 #
 357 # to say "export LESS=FRX (and LV=-c) if the environment variable
 358 # LESS (and LV) is not set, respectively".
 359 #
 360 # Define TEST_SHELL_PATH if you want to use a shell besides SHELL_PATH for
 361 # running the test scripts (e.g., bash has better support for "set -x"
 362 # tracing).
 363 #
 364 # When cross-compiling, define HOST_CPU as the canonical name of the CPU on
 365 # which the built Git will run (for instance "x86_64").
 366 #
 367 # Define RUNTIME_PREFIX to configure Git to resolve its ancillary tooling and
 368 # support files relative to the location of the runtime binary, rather than
 369 # hard-coding them into the binary. Git installations built with RUNTIME_PREFIX
 370 # can be moved to arbitrary filesystem locations. RUNTIME_PREFIX also causes
 371 # Perl scripts to use a modified entry point header allowing them to resolve
 372 # support files at runtime.
 373 #
 374 # When using RUNTIME_PREFIX, define HAVE_BSD_KERN_PROC_SYSCTL if your platform
 375 # supports the KERN_PROC BSD sysctl function.
 376 #
 377 # When using RUNTIME_PREFIX, define PROCFS_EXECUTABLE_PATH if your platform
 378 # mounts a "procfs" filesystem capable of resolving the path of the current
 379 # executable. If defined, this must be the canonical path for the "procfs"
 380 # current executable path.
 381 #
 382 # When using RUNTIME_PREFIX, define HAVE_NS_GET_EXECUTABLE_PATH if your platform
 383 # supports calling _NSGetExecutablePath to retrieve the path of the running
 384 # executable.
 385 #
 386 # When using RUNTIME_PREFIX, define HAVE_ZOS_GET_EXECUTABLE_PATH if your platform
 387 # supports calling __getprogramdir and getprogname to retrieve the path of the
 388 # running executable.
 389 #
 390 # When using RUNTIME_PREFIX, define HAVE_WPGMPTR if your platform offers
 391 # the global variable _wpgmptr containing the absolute path of the current
 392 # executable (this is the case on Windows).
 393 #
 394 # INSTALL_STRIP can be set to "-s" to strip binaries during installation,
 395 # if your $(INSTALL) command supports the option.
 396 #
 397 # Define GENERATE_COMPILATION_DATABASE to "yes" to generate JSON compilation
 398 # database entries during compilation if your compiler supports it, using the
 399 # `-MJ` flag. The JSON entries will be placed in the `compile_commands/`
 400 # directory, and the JSON compilation database 'compile_commands.json' will be
 401 # created at the root of the repository.
 402 #
 403 # If your platform supports a built-in fsmonitor backend, set
 404 # FSMONITOR_DAEMON_BACKEND to the "<name>" of the corresponding
 405 # `compat/fsmonitor/fsm-listen-<name>.c` and
 406 # `compat/fsmonitor/fsm-health-<name>.c` files
 407 # that implement the `fsm_listen__*()` and `fsm_health__*()` routines.
 408 #
 409 # If your platform has OS-specific ways to tell if a repo is incompatible with
 410 # fsmonitor (whether the hook or IPC daemon version), set FSMONITOR_OS_SETTINGS
 411 # to the "<name>" of the corresponding `compat/fsmonitor/fsm-settings-<name>.c`
 412 # that implements the `fsm_os_settings__*()` routines.
 413 #
 414 # Define LINK_FUZZ_PROGRAMS if you want `make all` to also build the fuzz test
 415 # programs in oss-fuzz/.
 416 #
 417 # Define INCLUDE_LIBGIT_RS if you want `make all` and `make test` to build and
 418 # test the Rust crates in contrib/libgit-sys and contrib/libgit-rs.
 419 #
 420 # === Optional library: libintl ===
 421 #
 422 # Define NO_GETTEXT if you don't want Git output to be translated.
 423 # A translated Git requires GNU libintl or another gettext implementation,
 424 # plus libintl-perl at runtime.
 425 #
 426 # Define USE_GETTEXT_SCHEME and set it to 'fallthrough', if you don't trust
 427 # the installed gettext translation of the shell scripts output.
 428 #
 429 # Define HAVE_LIBCHARSET_H if you haven't set NO_GETTEXT and you can't
 430 # trust the langinfo.h's nl_langinfo(CODESET) function to return the
 431 # current character set. GNU and Solaris have a nl_langinfo(CODESET),
 432 # FreeBSD can use either, but MinGW and some others need to use
 433 # libcharset.h's locale_charset() instead.
 434 #
 435 # Define CHARSET_LIB to the library you need to link with in order to
 436 # use locale_charset() function.  On some platforms this needs to set to
 437 # -lcharset, on others to -liconv .
 438 #
 439 # Define LIBC_CONTAINS_LIBINTL if your gettext implementation doesn't
 440 # need -lintl when linking.
 441 #
 442 # Define NO_MSGFMT_EXTENDED_OPTIONS if your implementation of msgfmt
 443 # doesn't support GNU extensions like --check and --statistics
 444 #
 445 # === Optional library: libexpat ===
 446 #
 447 # Define NO_EXPAT if you do not have expat installed.  git-http-push is
 448 # not built, and you cannot push using http:// and https:// transports (dumb).
 449 #
 450 # Define EXPATDIR=/foo/bar if your expat header and library files are in
 451 # /foo/bar/include and /foo/bar/lib directories.
 452 #
 453 # Define EXPAT_NEEDS_XMLPARSE_H if you have an old version of expat (e.g.,
 454 # 1.1 or 1.2) that provides xmlparse.h instead of expat.h.
 455
 456 # === Optional library: libcurl ===
 457 #
 458 # Define NO_CURL if you do not have libcurl installed.  git-http-fetch and
 459 # git-http-push are not built, and you cannot use http:// and https://
 460 # transports (neither smart nor dumb).
 461 #
 462 # Define CURLDIR=/foo/bar if your curl header and library files are in
 463 # /foo/bar/include and /foo/bar/lib directories.
 464 #
 465 # Define CURL_CONFIG to curl's configuration program that prints information
 466 # about the library (e.g., its version number).  The default is 'curl-config'.
 467 #
 468 # Define CURL_LDFLAGS to specify flags that you need to link when using libcurl,
 469 # if you do not want to rely on the libraries provided by CURL_CONFIG.  The
 470 # default value is a result of `curl-config --libs`.  An example value for
 471 # CURL_LDFLAGS is as follows:
 472 #
 473 #     CURL_LDFLAGS=-lcurl
 474 #
 475 # === Optional library: libpcre2 ===
 476 #
 477 # Define USE_LIBPCRE if you have and want to use libpcre. Various
 478 # commands such as log and grep offer runtime options to use
 479 # Perl-compatible regular expressions instead of standard or extended
 480 # POSIX regular expressions.
 481 #
 482 # Only libpcre version 2 is supported. USE_LIBPCRE2 is a synonym for
 483 # USE_LIBPCRE, support for the old USE_LIBPCRE1 has been removed.
 484 #
 485 # Define LIBPCREDIR=/foo/bar if your PCRE header and library files are
 486 # in /foo/bar/include and /foo/bar/lib directories.
 487 #
 488 # == SHA-1 and SHA-256 defines ==
 489 #
 490 # === SHA-1 backend ===
 491 #
 492 # ==== Security ====
 493 #
 494 # Due to the SHAttered (https://shattered.io) attack vector on SHA-1
 495 # it's strongly recommended to use the sha1collisiondetection
 496 # counter-cryptanalysis library for SHA-1 hashing.
 497 #
 498 # If you know that you can trust the repository contents, or where
 499 # potential SHA-1 attacks are otherwise mitigated the other backends
 500 # listed in "SHA-1 implementations" are faster than
 501 # sha1collisiondetection.
 502 #
 503 # ==== Default SHA-1 backend ====
 504 #
 505 # If no *_SHA1 backend is picked, the first supported one listed in
 506 # "SHA-1 implementations" will be picked.
 507 #
 508 # ==== Options common to all SHA-1 implementations ====
 509 #
 510 # Define SHA1_MAX_BLOCK_SIZE to limit the amount of data that will be hashed
 511 # in one call to the platform's SHA1_Update(). e.g. APPLE_COMMON_CRYPTO
 512 # wants 'SHA1_MAX_BLOCK_SIZE=1024L*1024L*1024L' defined.
 513 #
 514 # ==== SHA-1 implementations ====
 515 #
 516 # Define OPENSSL_SHA1 to link to the SHA-1 routines from the OpenSSL
 517 # library.
 518 #
 519 # Define BLK_SHA1 to make use of optimized C SHA-1 routines bundled
 520 # with git (in the block-sha1/ directory).
 521 #
 522 # Define APPLE_COMMON_CRYPTO_SHA1 to use Apple's CommonCrypto for
 523 # SHA-1.
 524 #
 525 # Define the same Makefile knobs as above, but suffixed with _UNSAFE to
 526 # use the corresponding implementations for unsafe SHA-1 hashing for
 527 # non-cryptographic purposes.
 528 #
 529 # If don't enable any of the *_SHA1 settings in this section, Git will
 530 # default to its built-in sha1collisiondetection library, which is a
 531 # collision-detecting sha1 This is slower, but may detect attempted
 532 # collision attacks.
 533 #
 534 # ==== Options for the sha1collisiondetection library ====
 535 #
 536 # Define DC_SHA1_EXTERNAL if you want to build / link
 537 # git with the external SHA1 collision-detect library.
 538 # Without this option, i.e. the default behavior is to build git with its
 539 # own built-in code (or submodule).
 540 #
 541 # Define DC_SHA1_SUBMODULE to use the
 542 # sha1collisiondetection shipped as a submodule instead of the
 543 # non-submodule copy in sha1dc/. This is an experimental option used
 544 # by the git project to migrate to using sha1collisiondetection as a
 545 # submodule.
 546 #
 547 # === SHA-256 backend ===
 548 #
 549 # ==== Security ====
 550 #
 551 # Unlike SHA-1 the SHA-256 algorithm does not suffer from any known
 552 # vulnerabilities, so any implementation will do.
 553 #
 554 # ==== SHA-256 implementations ====
 555 #
 556 # Define OPENSSL_SHA256 to use the SHA-256 routines in OpenSSL.
 557 #
 558 # Define NETTLE_SHA256 to use the SHA-256 routines in libnettle.
 559 #
 560 # Define GCRYPT_SHA256 to use the SHA-256 routines in libgcrypt.
 561 #
 562 # If don't enable any of the *_SHA256 settings in this section, Git
 563 # will default to its built-in sha256 implementation.
 564 #
 565 # == DEVELOPER defines ==
 566 #
 567 # Define DEVELOPER to enable more compiler warnings. Compiler version
 568 # and family are auto detected, but could be overridden by defining
 569 # COMPILER_FEATURES (see config.mak.dev). You can still set
 570 # CFLAGS="..." in combination with DEVELOPER enables, whether that's
 571 # for tweaking something unrelated (e.g. optimization level), or for
 572 # selectively overriding something DEVELOPER or one of the DEVOPTS
 573 # (see just below) brings in.
 574 #
 575 # When DEVELOPER is set, DEVOPTS can be used to control compiler
 576 # options.  This variable contains keywords separated by
 577 # whitespace. The following keywords are recognized:
 578 #
 579 #    no-error:
 580 #
 581 #        suppresses the -Werror that implicitly comes with
 582 #        DEVELOPER=1. Useful for getting the full set of errors
 583 #        without immediately dying, or for logging them.
 584 #
 585 #    extra-all:
 586 #
 587 #        The DEVELOPER mode enables -Wextra with a few exceptions. By
 588 #        setting this flag the exceptions are removed, and all of
 589 #        -Wextra is used.
 590 #
 591 #    no-pedantic:
 592 #
 593 #        Disable -pedantic compilation.
 594
 595 # Set our default configuration.
 596 #
 597 # Among the variables below, these:
 598 #   gitexecdir
 599 #   template_dir
 600 #   sysconfdir
 601 # can be specified as a relative path some/where/else;
 602 # this is interpreted as relative to $(prefix) and "git" built with
 603 # RUNTIME_PREFIX flag will figure out (at runtime) where they are
 604 # based on the path to the executable.
 605 # Additionally, the following will be treated as relative by "git" if they
 606 # begin with "$(prefix)/":
 607 #   mandir
 608 #   infodir
 609 #   htmldir
 610 #   localedir
 611 #   perllibdir
 612 # This can help installing the suite in a relocatable way.

1445 #
1446 # - Will make incremental development of *.cocci slower, as
1447 #   e.g. changing strbuf.cocci will re-run all *.cocci.
1448 #
1449 # - Makes error and performance analysis harder, as rules will be
1450 #   applied from a monolithic ALL.cocci, rather than
1451 #   e.g. strbuf.cocci. To work around this either undefine this, or

2505 ### Target-specific flags and dependencies
2506
2507 # The generic compilation pattern rule and automatically
2508 # computed header dependencies (falling back to a dependency on
2509 # LIB_H) are enough to describe how most targets should be built,
2510 # but some targets are special enough to need something a little
2511 # different.
2512 #
2513 # - When a source file "foo.c" #includes a generated header file,
2514 #   we need to list that dependency for the "foo.o" target.
2515 #
2516 #   We also list it from other targets that are built from foo.c
2517 #   like "foo.sp" and "foo.s", even though that is easy to forget
2518 #   to do because the generated header is already present around
2519 #   after a regular build attempt.
2520 #
2521 # - Some code depends on configuration kept in makefile
2522 #   variables. The target-specific variable EXTRA_CPPFLAGS can
2523 #   be used to convey that information to the C preprocessor
2524 #   using -D options.
2525 #
2526 #   The "foo.o" target should have a corresponding dependency on
2527 #   a file that changes when the value of the makefile variable
2528 #   changes.  For example, targets making use of the
2529 #   $(GIT_VERSION) variable depend on GIT-VERSION-FILE.
2530 #
2531 #   Technically the ".sp" and ".s" targets do not need this
2532 #   dependency because they are force-built, but they get the
2533 #   same dependency for consistency. This way, you do not have to
2534 #   know how each target is implemented. And it means the
2535 #   dependencies here will not need to change if the force-build
2536 #   details change some day.
