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 NO_OPENSSL environment variable if you do not have OpenSSL.
  26 #
  27 # Define USE_LIBPCRE if you have and want to use libpcre. Various
  28 # commands such as log and grep offer runtime options to use
  29 # Perl-compatible regular expressions instead of standard or extended
  30 # POSIX regular expressions.
  31 #
  32 # Currently USE_LIBPCRE is a synonym for USE_LIBPCRE1, define
  33 # USE_LIBPCRE2 instead if you'd like to use version 2 of the PCRE
  34 # library. The USE_LIBPCRE flag will likely be changed to mean v2 by
  35 # default in future releases.
  36 #
  37 # When using USE_LIBPCRE1, define NO_LIBPCRE1_JIT if the PCRE v1
  38 # library is compiled without --enable-jit. We will auto-detect
  39 # whether the version of the PCRE v1 library in use has JIT support at
  40 # all, but we unfortunately can't auto-detect whether JIT support
  41 # hasn't been compiled in in an otherwise JIT-supporting version. If
  42 # you have link-time errors about a missing `pcre_jit_exec` define
  43 # this, or recompile PCRE v1 with --enable-jit.
  44 #
  45 # Define LIBPCREDIR=/foo/bar if your PCRE header and library files are
  46 # in /foo/bar/include and /foo/bar/lib directories. Which version of
  47 # PCRE this points to determined by the USE_LIBPCRE1 and USE_LIBPCRE2
  48 # variables.
  49 #
  50 # Define HAVE_ALLOCA_H if you have working alloca(3) defined in that header.
  51 #
  52 # Define NO_CURL if you do not have libcurl installed.  git-http-fetch and
  53 # git-http-push are not built, and you cannot use http:// and https://
  54 # transports (neither smart nor dumb).
  55 #
  56 # Define CURLDIR=/foo/bar if your curl header and library files are in
  57 # /foo/bar/include and /foo/bar/lib directories.
  58 #
  59 # Define CURL_CONFIG to curl's configuration program that prints information
  60 # about the library (e.g., its version number).  The default is 'curl-config'.
  61 #
  62 # Define NO_EXPAT if you do not have expat installed.  git-http-push is
  63 # not built, and you cannot push using http:// and https:// transports (dumb).
  64 #
  65 # Define EXPATDIR=/foo/bar if your expat header and library files are in
  66 # /foo/bar/include and /foo/bar/lib directories.
  67 #
  68 # Define EXPAT_NEEDS_XMLPARSE_H if you have an old version of expat (e.g.,
  69 # 1.1 or 1.2) that provides xmlparse.h instead of expat.h.
  70 #
  71 # Define NO_GETTEXT if you don't want Git output to be translated.
  72 # A translated Git requires GNU libintl or another gettext implementation,
  73 # plus libintl-perl at runtime.
  74 #
  75 # Define USE_GETTEXT_SCHEME and set it to 'fallthrough', if you don't trust
  76 # the installed gettext translation of the shell scripts output.
  77 #
  78 # Define HAVE_LIBCHARSET_H if you haven't set NO_GETTEXT and you can't
  79 # trust the langinfo.h's nl_langinfo(CODESET) function to return the
  80 # current character set. GNU and Solaris have a nl_langinfo(CODESET),
  81 # FreeBSD can use either, but MinGW and some others need to use
  82 # libcharset.h's locale_charset() instead.
  83 #
  84 # Define CHARSET_LIB to the library you need to link with in order to
  85 # use locale_charset() function.  On some platforms this needs to set to
  86 # -lcharset, on others to -liconv .
  87 #
  88 # Define LIBC_CONTAINS_LIBINTL if your gettext implementation doesn't
  89 # need -lintl when linking.
  90 #
  91 # Define NO_MSGFMT_EXTENDED_OPTIONS if your implementation of msgfmt
  92 # doesn't support GNU extensions like --check and --statistics
  93 #
  94 # Define HAVE_PATHS_H if you have paths.h and want to use the default PATH
  95 # it specifies.
  96 #
  97 # Define NO_D_TYPE_IN_DIRENT if your platform defines DT_UNKNOWN but lacks
  98 # d_type in struct dirent (Cygwin 1.5, fixed in Cygwin 1.7).
  99 #
 100 # Define HAVE_STRINGS_H if you have strings.h and need it for strcasecmp.
 101 #
 102 # Define NO_STRCASESTR if you don't have strcasestr.
 103 #
 104 # Define NO_MEMMEM if you don't have memmem.
 105 #
 106 # Define NO_GETPAGESIZE if you don't have getpagesize.
 107 #
 108 # Define NO_STRLCPY if you don't have strlcpy.
 109 #
 110 # Define NO_STRTOUMAX if you don't have both strtoimax and strtoumax in the
 111 # C library. If your compiler also does not support long long or does not have
 112 # strtoull, define NO_STRTOULL.
 113 #
 114 # Define NO_SETENV if you don't have setenv in the C library.
 115 #
 116 # Define NO_UNSETENV if you don't have unsetenv in the C library.
 117 #
 118 # Define NO_MKDTEMP if you don't have mkdtemp in the C library.
 119 #
 120 # Define MKDIR_WO_TRAILING_SLASH if your mkdir() can't deal with trailing slash.
 121 #
 122 # Define NO_GECOS_IN_PWENT if you don't have pw_gecos in struct passwd
 123 # in the C library.
 124 #
 125 # Define NO_LIBGEN_H if you don't have libgen.h.
 126 #
 127 # Define NEEDS_LIBGEN if your libgen needs -lgen when linking
 128 #
 129 # Define NO_SYS_SELECT_H if you don't have sys/select.h.
 130 #
 131 # Define NO_SYMLINK_HEAD if you never want .git/HEAD to be a symbolic link.
 132 # Enable it on Windows.  By default, symrefs are still used.
 133 #
 134 # Define NO_SVN_TESTS if you want to skip time-consuming SVN interoperability
 135 # tests.  These tests take up a significant amount of the total test time
 136 # but are not needed unless you plan to talk to SVN repos.
 137 #
 138 # Define NO_FINK if you are building on Darwin/Mac OS X, have Fink
 139 # installed in /sw, but don't want GIT to link against any libraries
 140 # installed there.  If defined you may specify your own (or Fink's)
 141 # include directories and library directories by defining CFLAGS
 142 # and LDFLAGS appropriately.
 143 #
 144 # Define NO_DARWIN_PORTS if you are building on Darwin/Mac OS X,
 145 # have DarwinPorts installed in /opt/local, but don't want GIT to
 146 # link against any libraries installed there.  If defined you may
 147 # specify your own (or DarwinPort's) include directories and
 148 # library directories by defining CFLAGS and LDFLAGS appropriately.
 149 #
 150 # Define NO_APPLE_COMMON_CRYPTO if you are building on Darwin/Mac OS X
 151 # and do not want to use Apple's CommonCrypto library.  This allows you
 152 # to provide your own OpenSSL library, for example from MacPorts.
 153 #
 154 # Define BLK_SHA1 environment variable to make use of the bundled
 155 # optimized C SHA1 routine.
 156 #
 157 # Define PPC_SHA1 environment variable when running make to make use of
 158 # a bundled SHA1 routine optimized for PowerPC.
 159 #
 160 # Define DC_SHA1 to unconditionally enable the collision-detecting sha1
 161 # algorithm. This is slower, but may detect attempted collision attacks.
 162 # Takes priority over other *_SHA1 knobs.
 163 #
 164 # Define DC_SHA1_EXTERNAL in addition to DC_SHA1 if you want to build / link
 165 # git with the external SHA1 collision-detect library.
 166 # Without this option, i.e. the default behavior is to build git with its
 167 # own built-in code (or submodule).
 168 #
 169 # Define DC_SHA1_SUBMODULE in addition to DC_SHA1 to use the
 170 # sha1collisiondetection shipped as a submodule instead of the
 171 # non-submodule copy in sha1dc/. This is an experimental option used
 172 # by the git project to migrate to using sha1collisiondetection as a
 173 # submodule.
 174 #
 175 # Define OPENSSL_SHA1 environment variable when running make to link
 176 # with the SHA1 routine from openssl library.
 177 #
 178 # Define SHA1_MAX_BLOCK_SIZE to limit the amount of data that will be hashed
 179 # in one call to the platform's SHA1_Update(). e.g. APPLE_COMMON_CRYPTO
 180 # wants 'SHA1_MAX_BLOCK_SIZE=1024L*1024L*1024L' defined.
 181 #
 182 # Define NEEDS_CRYPTO_WITH_SSL if you need -lcrypto when using -lssl (Darwin).
 183 #
 184 # Define NEEDS_SSL_WITH_CRYPTO if you need -lssl when using -lcrypto (Darwin).
 185 #
 186 # Define NEEDS_SSL_WITH_CURL if you need -lssl with -lcurl (Minix).
 187 #
 188 # Define NEEDS_IDN_WITH_CURL if you need -lidn when using -lcurl (Minix).
 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_SYS_POLL_H if you don't have sys/poll.h.
 211 #
 212 # Define NO_POLL if you do not have or don't want to use poll().
 213 # This also implies NO_SYS_POLL_H.
 214 #
 215 # Define NEEDS_SYS_PARAM_H if you need to include sys/param.h to compile,
 216 # *PLEASE* REPORT to git@vger.kernel.org if your platform needs this;
 217 # we want to know more about the issue.
 218 #
 219 # Define NO_PTHREADS if you do not have or do not want to use Pthreads.
 220 #
 221 # Define NO_PREAD if you have a problem with pread() system call (e.g.
 222 # cygwin1.dll before v1.5.22).
 223 #
 224 # Define NO_SETITIMER if you don't have setitimer()
 225 #
 226 # Define NO_STRUCT_ITIMERVAL if you don't have struct itimerval
 227 # This also implies NO_SETITIMER
 228 #
 229 # Define NO_FAST_WORKING_DIRECTORY if accessing objects in pack files is
 230 # generally faster on your platform than accessing the working directory.
 231 #
 232 # Define NO_TRUSTABLE_FILEMODE if your filesystem may claim to support
 233 # the executable mode bit, but doesn't really do so.
 234 #
 235 # Define NEEDS_MODE_TRANSLATION if your OS strays from the typical file type
 236 # bits in mode values (e.g. z/OS defines I_SFMT to 0xFF000000 as opposed to the
 237 # usual 0xF000).
 238 #
 239 # Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
 240 #
 241 # Define NO_UNIX_SOCKETS if your system does not offer unix sockets.
 242 #
 243 # Define NO_SOCKADDR_STORAGE if your platform does not have struct
 244 # sockaddr_storage.
 245 #
 246 # Define NO_ICONV if your libc does not properly support iconv.
 247 #
 248 # Define OLD_ICONV if your library has an old iconv(), where the second
 249 # (input buffer pointer) parameter is declared with type (const char **).
 250 #
 251 # Define NO_DEFLATE_BOUND if your zlib does not have deflateBound.
 252 #
 253 # Define NO_R_TO_GCC_LINKER if your gcc does not like "-R/path/lib"
 254 # that tells runtime paths to dynamic libraries;
 255 # "-Wl,-rpath=/path/lib" is used instead.
 256 #
 257 # Define NO_NORETURN if using buggy versions of gcc 4.6+ and profile feedback,
 258 # as the compiler can crash (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49299)
 259 #
 260 # Define USE_NSEC below if you want git to care about sub-second file mtimes
 261 # and ctimes. Note that you need recent glibc (at least 2.2.4) for this. On
 262 # Linux, kernel 2.6.11 or newer is required for reliable sub-second file times
 263 # on file systems with exactly 1 ns or 1 s resolution. If you intend to use Git
 264 # on other file systems (e.g. CEPH, CIFS, NTFS, UDF), don't enable USE_NSEC. See
 265 # Documentation/technical/racy-git.txt for details.
 266 #
 267 # Define USE_ST_TIMESPEC if your "struct stat" uses "st_ctimespec" instead of
 268 # "st_ctim"
 269 #
 270 # Define NO_NSEC if your "struct stat" does not have "st_ctim.tv_nsec"
 271 # available.  This automatically turns USE_NSEC off.
 272 #
 273 # Define USE_STDEV below if you want git to care about the underlying device
 274 # change being considered an inode change from the update-index perspective.
 275 #
 276 # Define NO_ST_BLOCKS_IN_STRUCT_STAT if your platform does not have st_blocks
 277 # field that counts the on-disk footprint in 512-byte blocks.
 278 #
 279 # Define DOCBOOK_XSL_172 if you want to format man pages with DocBook XSL v1.72
 280 # (not v1.73 or v1.71).
 281 #
 282 # Define ASCIIDOC_ROFF if your DocBook XSL does not escape raw roff directives
 283 # (versions 1.68.1 through v1.72).
 284 #
 285 # Define GNU_ROFF if your target system uses GNU groff.  This forces
 286 # apostrophes to be ASCII so that cut&pasting examples to the shell
 287 # will work.
 288 #
 289 # Define USE_ASCIIDOCTOR to use Asciidoctor instead of AsciiDoc to build the
 290 # documentation.
 291 #
 292 # Define ASCIIDOCTOR_EXTENSIONS_LAB to point to the location of the Asciidoctor
 293 # Extensions Lab if you have it available.
 294 #
 295 # Define PERL_PATH to the path of your Perl binary (usually /usr/bin/perl).
 296 #
 297 # Define NO_PERL_MAKEMAKER if you cannot use Makefiles generated by perl's
 298 # MakeMaker (e.g. using ActiveState under Cygwin).
 299 #
 300 # Define NO_PERL if you do not want Perl scripts or libraries at all.
 301 #
 302 # Define PYTHON_PATH to the path of your Python binary (often /usr/bin/python
 303 # but /usr/bin/python2.7 on some platforms).
 304 #
 305 # Define NO_PYTHON if you do not want Python scripts or libraries at all.
 306 #
 307 # Define NO_TCLTK if you do not want Tcl/Tk GUI.
 308 #
 309 # Define SANE_TEXT_GREP to "-a" if you use recent versions of GNU grep
 310 # and egrep that are pickier when their input contains non-ASCII data.
 311 #
 312 # The TCL_PATH variable governs the location of the Tcl interpreter
 313 # used to optimize git-gui for your system.  Only used if NO_TCLTK
 314 # is not set.  Defaults to the bare 'tclsh'.
 315 #
 316 # The TCLTK_PATH variable governs the location of the Tcl/Tk interpreter.
 317 # If not set it defaults to the bare 'wish'. If it is set to the empty
 318 # string then NO_TCLTK will be forced (this is used by configure script).
 319 #
 320 # Define INTERNAL_QSORT to use Git's implementation of qsort(), which
 321 # is a simplified version of the merge sort used in glibc. This is
 322 # recommended if Git triggers O(n^2) behavior in your platform's qsort().
 323 #
 324 # Define HAVE_ISO_QSORT_S if your platform provides a qsort_s() that's
 325 # compatible with the one described in C11 Annex K.
 326 #
 327 # Define UNRELIABLE_FSTAT if your system's fstat does not return the same
 328 # information on a not yet closed file that lstat would return for the same
 329 # file after it was closed.
 330 #
 331 # Define OBJECT_CREATION_USES_RENAMES if your operating systems has problems
 332 # when hardlinking a file to another name and unlinking the original file right
 333 # away (some NTFS drivers seem to zero the contents in that scenario).
 334 #
 335 # Define NO_CROSS_DIRECTORY_HARDLINKS if you plan to distribute the installed
 336 # programs as a tar, where bin/ and libexec/ might be on different file systems.
 337 #
 338 # Define NO_INSTALL_HARDLINKS if you prefer to use either symbolic links or
 339 # copies to install built-in git commands e.g. git-cat-file.
 340 #
 341 # Define USE_NED_ALLOCATOR if you want to replace the platforms default
 342 # memory allocators with the nedmalloc allocator written by Niall Douglas.
 343 #
 344 # Define OVERRIDE_STRDUP to override the libc version of strdup(3).
 345 # This is necessary when using a custom allocator in order to avoid
 346 # crashes due to allocation and free working on different 'heaps'.
 347 # It's defined automatically if USE_NED_ALLOCATOR is set.
 348 #
 349 # Define NO_REGEX if your C library lacks regex support with REG_STARTEND
 350 # feature.
 351 #
 352 # Define HAVE_DEV_TTY if your system can open /dev/tty to interact with the
 353 # user.
 354 #
 355 # Define GETTEXT_POISON if you are debugging the choice of strings marked
 356 # for translation.  In a GETTEXT_POISON build, you can turn all strings marked

 359 #
 360 # Define JSMIN to point to JavaScript minifier that functions as
 361 # a filter to have gitweb.js minified.
 362 #

 364 # version of gitweb.css
 365 #
 366 # Define DEFAULT_PAGER to a sensible pager command (defaults to "less") if
 367 # you want to use something different.  The value will be interpreted by the
 368 # shell at runtime when it is used.
 369 #
 370 # Define DEFAULT_EDITOR to a sensible editor command (defaults to "vi") if you
 371 # want to use something different.  The value will be interpreted by the shell
 372 # if necessary when it is used.  Examples:
 373 #
 374 #   DEFAULT_EDITOR='~/bin/vi',
 375 #   DEFAULT_EDITOR='$GIT_FALLBACK_EDITOR',
 376 #   DEFAULT_EDITOR='"C:\Program Files\Vim\gvim.exe" --nofork'
 377 #
 378 # Define COMPUTE_HEADER_DEPENDENCIES to "yes" if you want dependencies on
 379 # header files to be automatically computed, to avoid rebuilding objects when
 380 # an unrelated header file changes.  Define it to "no" to use the hard-coded
 381 # dependency rules.  The default is "auto", which means to use computed header
 382 # dependencies if your compiler is detected to support it.
 383 #
 384 # Define NATIVE_CRLF if your platform uses CRLF for line endings.
 385 #
 386 # Define GIT_USER_AGENT if you want to change how git identifies itself during
 387 # network interactions.  The default is "git/$(GIT_VERSION)".
 388 #
 389 # Define DEFAULT_HELP_FORMAT to "man", "info" or "html"
 390 # (defaults to "man") if you want to have a different default when
 391 # "git help" is called without a parameter specifying the format.
 392 #
 393 # Define TEST_GIT_INDEX_VERSION to 2, 3 or 4 to run the test suite
 394 # with a different indexfile format version.  If it isn't set the index
 395 # file format used is index-v[23].
 396 #
 397 # Define GMTIME_UNRELIABLE_ERRORS if your gmtime() function does not
 398 # return NULL when it receives a bogus time_t.
 399 #
 400 # Define HAVE_CLOCK_GETTIME if your platform has clock_gettime.
 401 #
 402 # Define HAVE_CLOCK_MONOTONIC if your platform has CLOCK_MONOTONIC.
 403 #
 404 # Define NEEDS_LIBRT if your platform requires linking with librt (glibc version
 405 # before 2.17) for clock_gettime and CLOCK_MONOTONIC.
 406 #
 407 # Define USE_PARENS_AROUND_GETTEXT_N to "yes" if your compiler happily
 408 # compiles the following initialization:
 409 #
 410 #   static const char s[] = ("FOO");
 411 #
 412 # and define it to "no" if you need to remove the parentheses () around the
 413 # constant.  The default is "auto", which means to use parentheses if your
 414 # compiler is detected to support it.
 415 #
 416 # Define HAVE_BSD_SYSCTL if your platform has a BSD-compatible sysctl function.
 417 #
 418 # Define HAVE_GETDELIM if your system has the getdelim() function.
 419 #
 420 # Define PAGER_ENV to a SP separated VAR=VAL pairs to define
 421 # default environment variables to be passed when a pager is spawned, e.g.
 422 #
 423 #    PAGER_ENV = LESS=FRX LV=-c
 424 #
 425 # to say "export LESS=FRX (and LV=-c) if the environment variable
 426 # LESS (and LV) is not set, respectively".
 427 #
 428 # Define TEST_SHELL_PATH if you want to use a shell besides SHELL_PATH for
 429 # running the test scripts (e.g., bash has better support for "set -x"
 430 # tracing).
 431 #
 432 # When cross-compiling, define HOST_CPU as the canonical name of the CPU on
 433 # which the built Git will run (for instance "x86_64").
 434 #
 435 # Define DEVELOPER to enable more compiler warnings. Compiler version
 436 # and family are auto detected, but could be overridden by defining
 437 # COMPILER_FEATURES (see config.mak.dev)

1855 ### Target-specific flags and dependencies
1856
1857 # The generic compilation pattern rule and automatically
1858 # computed header dependencies (falling back to a dependency on
1859 # LIB_H) are enough to describe how most targets should be built,
1860 # but some targets are special enough to need something a little
1861 # different.
1862 #
1863 # - When a source file "foo.c" #includes a generated header file,
1864 #   we need to list that dependency for the "foo.o" target.
1865 #
1866 #   We also list it from other targets that are built from foo.c
1867 #   like "foo.sp" and "foo.s", even though that is easy to forget
1868 #   to do because the generated header is already present around
1869 #   after a regular build attempt.
1870 #
1871 # - Some code depends on configuration kept in makefile
1872 #   variables. The target-specific variable EXTRA_CPPFLAGS can
1873 #   be used to convey that information to the C preprocessor
1874 #   using -D options.
1875 #
1876 #   The "foo.o" target should have a corresponding dependency on
1877 #   a file that changes when the value of the makefile variable
1878 #   changes.  For example, targets making use of the
1879 #   $(GIT_VERSION) variable depend on GIT-VERSION-FILE.
1880 #
1881 #   Technically the ".sp" and ".s" targets do not need this
1882 #   dependency because they are force-built, but they get the
1883 #   same dependency for consistency. This way, you do not have to
1884 #   know how each target is implemented. And it means the
1885 #   dependencies here will not need to change if the force-build
1886 #   details change some day.
