   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.
  23 #
  24 # Define NO_OPENSSL environment variable if you do not have OpenSSL.
  25 # This also implies BLK_SHA1.
  26 #
  27 # Define USE_LIBPCRE if you have and want to use libpcre. git-grep will be
  28 # able to use Perl-compatible regular expressions.
  29 #
  30 # Define LIBPCREDIR=/foo/bar if your libpcre header and library files are in
  31 # /foo/bar/include and /foo/bar/lib directories.
  32 #
  33 # Define HAVE_ALLOCA_H if you have working alloca(3) defined in that header.
  34 #
  35 # Define NO_CURL if you do not have libcurl installed.  git-http-fetch and
  36 # git-http-push are not built, and you cannot use http:// and https://
  37 # transports (neither smart nor dumb).
  38 #

  40 # /foo/bar/include and /foo/bar/lib directories.
  41 #
  42 # Define CURL_CONFIG to curl's configuration program that prints information
  43 # about the library (e.g., its version number).  The default is 'curl-config'.

  52 # 1.1 or 1.2) that provides xmlparse.h instead of expat.h.
  53 #
  54 # Define NO_GETTEXT if you don't want Git output to be translated.
  55 # A translated Git requires GNU libintl or another gettext implementation,
  56 # plus libintl-perl at runtime.
  57 #
  58 # Define USE_GETTEXT_SCHEME and set it to 'fallthrough', if you don't trust
  59 # the installed gettext translation of the shell scripts output.
  60 #
  61 # Define HAVE_LIBCHARSET_H if you haven't set NO_GETTEXT and you can't
  62 # trust the langinfo.h's nl_langinfo(CODESET) function to return the
  63 # current character set. GNU and Solaris have a nl_langinfo(CODESET),
  64 # FreeBSD can use either, but MinGW and some others need to use
  65 # libcharset.h's locale_charset() instead.
  66 #
  67 # Define CHARSET_LIB to the library you need to link with in order to
  68 # use locale_charset() function.  On some platforms this needs to set to
  69 # -lcharset, on others to -liconv .
  70 #
  71 # Define LIBC_CONTAINS_LIBINTL if your gettext implementation doesn't
  72 # need -lintl when linking.

  75 # doesn't support GNU extensions like --check and --statistics
  76 #
  77 # Define HAVE_PATHS_H if you have paths.h and want to use the default PATH
  78 # it specifies.
  79 #
  80 # Define NO_D_TYPE_IN_DIRENT if your platform defines DT_UNKNOWN but lacks
  81 # d_type in struct dirent (Cygwin 1.5, fixed in Cygwin 1.7).
  82 #
  83 # Define HAVE_STRINGS_H if you have strings.h and need it for strcasecmp.

  92 #
  93 # Define NO_STRTOUMAX if you don't have both strtoimax and strtoumax in the
  94 # C library. If your compiler also does not support long long or does not have
  95 # strtoull, define NO_STRTOULL.

 109 #
 110 # Define NEEDS_LIBGEN if your libgen needs -lgen when linking
 111 #
 112 # Define NO_SYS_SELECT_H if you don't have sys/select.h.
 113 #
 114 # Define NO_SYMLINK_HEAD if you never want .git/HEAD to be a symbolic link.
 115 # Enable it on Windows.  By default, symrefs are still used.
 116 #
 117 # Define NO_SVN_TESTS if you want to skip time-consuming SVN interoperability
 118 # tests.  These tests take up a significant amount of the total test time
 119 # but are not needed unless you plan to talk to SVN repos.
 120 #
 121 # Define NO_FINK if you are building on Darwin/Mac OS X, have Fink
 122 # installed in /sw, but don't want GIT to link against any libraries
 123 # installed there.  If defined you may specify your own (or Fink's)
 124 # include directories and library directories by defining CFLAGS
 125 # and LDFLAGS appropriately.
 126 #
 127 # Define NO_DARWIN_PORTS if you are building on Darwin/Mac OS X,
 128 # have DarwinPorts installed in /opt/local, but don't want GIT to

 132 #
 133 # Define NO_APPLE_COMMON_CRYPTO if you are building on Darwin/Mac OS X
 134 # and do not want to use Apple's CommonCrypto library.  This allows you

 136 #
 137 # Define BLK_SHA1 environment variable to make use of the bundled
 138 # optimized C SHA1 routine.
 139 #
 140 # Define PPC_SHA1 environment variable when running make to make use of
 141 # a bundled SHA1 routine optimized for PowerPC.
 142 #
 143 # Define DC_SHA1 to unconditionally enable the collision-detecting sha1
 144 # algorithm. This is slower, but may detect attempted collision attacks.
 145 # Takes priority over other *_SHA1 knobs.
 146 #
 147 # Define OPENSSL_SHA1 environment variable when running make to link
 148 # with the SHA1 routine from openssl library.
 149 #
 150 # Define SHA1_MAX_BLOCK_SIZE to limit the amount of data that will be hashed
 151 # in one call to the platform's SHA1_Update(). e.g. APPLE_COMMON_CRYPTO
 152 # wants 'SHA1_MAX_BLOCK_SIZE=1024L*1024L*1024L' defined.
 153 #
 154 # Define NEEDS_CRYPTO_WITH_SSL if you need -lcrypto when using -lssl (Darwin).

 168 # Define NO_UINTMAX_T if you don't have uintmax_t.
 169 #
 170 # Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
 171 # Patrick Mauritz).
 172 #
 173 # Define NEEDS_RESOLV if linking with -lnsl and/or -lsocket is not enough.
 174 # Notably on Solaris hstrerror resides in libresolv and on Solaris 7
 175 # inet_ntop and inet_pton additionally reside there.
 176 #
 177 # Define NO_MMAP if you want to avoid mmap.
 178 #
 179 # Define NO_SYS_POLL_H if you don't have sys/poll.h.
 180 #
 181 # Define NO_POLL if you do not have or don't want to use poll().
 182 # This also implies NO_SYS_POLL_H.
 183 #
 184 # Define NEEDS_SYS_PARAM_H if you need to include sys/param.h to compile,
 185 # *PLEASE* REPORT to git@vger.kernel.org if your platform needs this;
 186 # we want to know more about the issue.
 187 #
 188 # Define NO_PTHREADS if you do not have or do not want to use Pthreads.
 189 #
 190 # Define NO_PREAD if you have a problem with pread() system call (e.g.

 192 #
 193 # Define NO_SETITIMER if you don't have setitimer()
 194 #
 195 # Define NO_STRUCT_ITIMERVAL if you don't have struct itimerval
 196 # This also implies NO_SETITIMER
 197 #
 198 # Define NO_FAST_WORKING_DIRECTORY if accessing objects in pack files is
 199 # generally faster on your platform than accessing the working directory.
 200 #
 201 # Define NO_TRUSTABLE_FILEMODE if your filesystem may claim to support
 202 # the executable mode bit, but doesn't really do so.
 203 #
 204 # Define NEEDS_MODE_TRANSLATION if your OS strays from the typical file type
 205 # bits in mode values (e.g. z/OS defines I_SFMT to 0xFF000000 as opposed to the
 206 # usual 0xF000).
 207 #
 208 # Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
 209 #
 210 # Define NO_UNIX_SOCKETS if your system does not offer unix sockets.
 211 #
 212 # Define NO_SOCKADDR_STORAGE if your platform does not have struct

 221 #
 222 # Define NO_R_TO_GCC_LINKER if your gcc does not like "-R/path/lib"
 223 # that tells runtime paths to dynamic libraries;
 224 # "-Wl,-rpath=/path/lib" is used instead.
 225 #
 226 # Define NO_NORETURN if using buggy versions of gcc 4.6+ and profile feedback,
 227 # as the compiler can crash (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49299)
 228 #
 229 # Define USE_NSEC below if you want git to care about sub-second file mtimes
 230 # and ctimes. Note that you need recent glibc (at least 2.2.4) for this. On
 231 # Linux, kernel 2.6.11 or newer is required for reliable sub-second file times
 232 # on file systems with exactly 1 ns or 1 s resolution. If you intend to use Git
 233 # on other file systems (e.g. CEPH, CIFS, NTFS, UDF), don't enable USE_NSEC. See
 234 # Documentation/technical/racy-git.txt for details.
 235 #
 236 # Define USE_ST_TIMESPEC if your "struct stat" uses "st_ctimespec" instead of
 237 # "st_ctim"
 238 #
 239 # Define NO_NSEC if your "struct stat" does not have "st_ctim.tv_nsec"
 240 # available.  This automatically turns USE_NSEC off.
 241 #
 242 # Define USE_STDEV below if you want git to care about the underlying device
 243 # change being considered an inode change from the update-index perspective.
 244 #
 245 # Define NO_ST_BLOCKS_IN_STRUCT_STAT if your platform does not have st_blocks
 246 # field that counts the on-disk footprint in 512-byte blocks.
 247 #
 248 # Define DOCBOOK_XSL_172 if you want to format man pages with DocBook XSL v1.72
 249 # (not v1.73 or v1.71).
 250 #
 251 # Define ASCIIDOC_ROFF if your DocBook XSL does not escape raw roff directives
 252 # (versions 1.68.1 through v1.72).
 253 #
 254 # Define GNU_ROFF if your target system uses GNU groff.  This forces
 255 # apostrophes to be ASCII so that cut&pasting examples to the shell
 256 # will work.
 257 #
 258 # Define USE_ASCIIDOCTOR to use Asciidoctor instead of AsciiDoc to build the
 259 # documentation.
 260 #
 261 # Define ASCIIDOCTOR_EXTENSIONS_LAB to point to the location of the Asciidoctor
 262 # Extensions Lab if you have it available.
 263 #
 264 # Define PERL_PATH to the path of your Perl binary (usually /usr/bin/perl).
 265 #
 266 # Define NO_PERL_MAKEMAKER if you cannot use Makefiles generated by perl's
 267 # MakeMaker (e.g. using ActiveState under Cygwin).
 268 #
 269 # Define NO_PERL if you do not want Perl scripts or libraries at all.
 270 #
 271 # Define PYTHON_PATH to the path of your Python binary (often /usr/bin/python
 272 # but /usr/bin/python2.7 on some platforms).
 273 #
 274 # Define NO_PYTHON if you do not want Python scripts or libraries at all.
 275 #
 276 # Define NO_TCLTK if you do not want Tcl/Tk GUI.
 277 #
 278 # Define SANE_TEXT_GREP to "-a" if you use recent versions of GNU grep
 279 # and egrep that are pickier when their input contains non-ASCII data.
 280 #
 281 # The TCL_PATH variable governs the location of the Tcl interpreter
 282 # used to optimize git-gui for your system.  Only used if NO_TCLTK
 283 # is not set.  Defaults to the bare 'tclsh'.
 284 #
 285 # The TCLTK_PATH variable governs the location of the Tcl/Tk interpreter.
 286 # If not set it defaults to the bare 'wish'. If it is set to the empty
 287 # string then NO_TCLTK will be forced (this is used by configure script).
 288 #
 289 # Define INTERNAL_QSORT to use Git's implementation of qsort(), which
 290 # is a simplified version of the merge sort used in glibc. This is
 291 # recommended if Git triggers O(n^2) behavior in your platform's qsort().
 292 #
 293 # Define HAVE_ISO_QSORT_S if your platform provides a qsort_s() that's
 294 # compatible with the one described in C11 Annex K.
 295 #
 296 # Define UNRELIABLE_FSTAT if your system's fstat does not return the same
 297 # information on a not yet closed file that lstat would return for the same
 298 # file after it was closed.
 299 #
 300 # Define OBJECT_CREATION_USES_RENAMES if your operating systems has problems
 301 # when hardlinking a file to another name and unlinking the original file right
 302 # away (some NTFS drivers seem to zero the contents in that scenario).
 303 #
 304 # Define NO_CROSS_DIRECTORY_HARDLINKS if you plan to distribute the installed
 305 # programs as a tar, where bin/ and libexec/ might be on different file systems.
 306 #
 307 # Define NO_INSTALL_HARDLINKS if you prefer to use either symbolic links or
 308 # copies to install built-in git commands e.g. git-cat-file.
 309 #
 310 # Define USE_NED_ALLOCATOR if you want to replace the platforms default
 311 # memory allocators with the nedmalloc allocator written by Niall Douglas.
 312 #
 313 # Define OVERRIDE_STRDUP to override the libc version of strdup(3).
 314 # This is necessary when using a custom allocator in order to avoid
 315 # crashes due to allocation and free working on different 'heaps'.
 316 # It's defined automatically if USE_NED_ALLOCATOR is set.
 317 #
 318 # Define NO_REGEX if your C library lacks regex support with REG_STARTEND
 319 # feature.
 320 #
 321 # Define HAVE_DEV_TTY if your system can open /dev/tty to interact with the
 322 # user.
 323 #
 324 # Define GETTEXT_POISON if you are debugging the choice of strings marked
 325 # for translation.  In a GETTEXT_POISON build, you can turn all strings marked
 326 # for translation into gibberish by setting the GIT_GETTEXT_POISON variable
 327 # (to any value) in your environment.
 328 #
 329 # Define JSMIN to point to JavaScript minifier that functions as
 330 # a filter to have gitweb.js minified.
 331 #
 332 # Define CSSMIN to point to a CSS minifier in order to generate a minified
 333 # version of gitweb.css
 334 #
 335 # Define DEFAULT_PAGER to a sensible pager command (defaults to "less") if
 336 # you want to use something different.  The value will be interpreted by the
 337 # shell at runtime when it is used.
 338 #
 339 # Define DEFAULT_EDITOR to a sensible editor command (defaults to "vi") if you
 340 # want to use something different.  The value will be interpreted by the shell
 341 # if necessary when it is used.  Examples:
 342 #
 343 #   DEFAULT_EDITOR='~/bin/vi',
 344 #   DEFAULT_EDITOR='$GIT_FALLBACK_EDITOR',
 345 #   DEFAULT_EDITOR='"C:\Program Files\Vim\gvim.exe" --nofork'
 346 #
 347 # Define COMPUTE_HEADER_DEPENDENCIES to "yes" if you want dependencies on
 348 # header files to be automatically computed, to avoid rebuilding objects when
 349 # an unrelated header file changes.  Define it to "no" to use the hard-coded
 350 # dependency rules.  The default is "auto", which means to use computed header
 351 # dependencies if your compiler is detected to support it.
 352 #
 353 # Define NATIVE_CRLF if your platform uses CRLF for line endings.
 354 #
 355 # Define GIT_USER_AGENT if you want to change how git identifies itself during
 356 # network interactions.  The default is "git/$(GIT_VERSION)".
 357 #
 358 # Define DEFAULT_HELP_FORMAT to "man", "info" or "html"
 359 # (defaults to "man") if you want to have a different default when
 360 # "git help" is called without a parameter specifying the format.
 361 #
 362 # Define TEST_GIT_INDEX_VERSION to 2, 3 or 4 to run the test suite
 363 # with a different indexfile format version.  If it isn't set the index
 364 # file format used is index-v[23].
 365 #
 366 # Define GMTIME_UNRELIABLE_ERRORS if your gmtime() function does not
 367 # return NULL when it receives a bogus time_t.
 368 #
 369 # Define HAVE_CLOCK_GETTIME if your platform has clock_gettime.
 370 #
 371 # Define HAVE_CLOCK_MONOTONIC if your platform has CLOCK_MONOTONIC.
 372 #
 373 # Define NEEDS_LIBRT if your platform requires linking with librt (glibc version
 374 # before 2.17) for clock_gettime and CLOCK_MONOTONIC.
 375 #
 376 # Define USE_PARENS_AROUND_GETTEXT_N to "yes" if your compiler happily
 377 # compiles the following initialization:
 378 #
 379 #   static const char s[] = ("FOO");
 380 #
 381 # and define it to "no" if you need to remove the parentheses () around the
 382 # constant.  The default is "auto", which means to use parentheses if your
 383 # compiler is detected to support it.
 384 #
 385 # Define HAVE_BSD_SYSCTL if your platform has a BSD-compatible sysctl function.
 386 #
 387 # Define HAVE_GETDELIM if your system has the getdelim() function.
 388 #

 390 # default environment variables to be passed when a pager is spawned, e.g.
 391 #
 392 #    PAGER_ENV = LESS=FRX LV=-c
 393 #

1738 ### Target-specific flags and dependencies
1739
1740 # The generic compilation pattern rule and automatically
1741 # computed header dependencies (falling back to a dependency on
1742 # LIB_H) are enough to describe how most targets should be built,
1743 # but some targets are special enough to need something a little
1744 # different.
1745 #
1746 # - When a source file "foo.c" #includes a generated header file,
1747 #   we need to list that dependency for the "foo.o" target.
1748 #
1749 #   We also list it from other targets that are built from foo.c
1750 #   like "foo.sp" and "foo.s", even though that is easy to forget
1751 #   to do because the generated header is already present around
1752 #   after a regular build attempt.
1753 #
1754 # - Some code depends on configuration kept in makefile
1755 #   variables. The target-specific variable EXTRA_CPPFLAGS can
1756 #   be used to convey that information to the C preprocessor
1757 #   using -D options.
1758 #
1759 #   The "foo.o" target should have a corresponding dependency on
1760 #   a file that changes when the value of the makefile variable
1761 #   changes.  For example, targets making use of the
1762 #   $(GIT_VERSION) variable depend on GIT-VERSION-FILE.
1763 #
1764 #   Technically the ".sp" and ".s" targets do not need this
1765 #   dependency because they are force-built, but they get the
1766 #   same dependency for consistency. This way, you do not have to
1767 #   know how each target is implemented. And it means the
1768 #   dependencies here will not need to change if the force-build
1769 #   details change some day.
