   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).

  40 # /foo/bar/include and /foo/bar/lib directories.
  41 #

  43 # about the library (e.g., its version number).  The default is 'curl-config'.
  44 #

  49 # /foo/bar/include and /foo/bar/lib directories.
  50 #
  51 # Define EXPAT_NEEDS_XMLPARSE_H if you have an old version of expat (e.g.,
  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.

  74 # Define NO_MSGFMT_EXTENDED_OPTIONS if your implementation of msgfmt
  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.

  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.

 110 # Define NO_LIBGEN_H if you don't have libgen.h.
 111 #
 112 # Define NEEDS_LIBGEN if your libgen needs -lgen when linking
 113 #
 114 # Define NO_SYS_SELECT_H if you don't have sys/select.h.
 115 #
 116 # Define NO_SYMLINK_HEAD if you never want .git/HEAD to be a symbolic link.
 117 # Enable it on Windows.  By default, symrefs are still used.
 118 #
 119 # Define NO_SVN_TESTS if you want to skip time-consuming SVN interoperability
 120 # tests.  These tests take up a significant amount of the total test time
 121 # but are not needed unless you plan to talk to SVN repos.
 122 #
 123 # Define NO_FINK if you are building on Darwin/Mac OS X, have Fink
 124 # installed in /sw, but don't want GIT to link against any libraries

 126 # include directories and library directories by defining CFLAGS
 127 # and LDFLAGS appropriately.
 128 #
 129 # Define NO_DARWIN_PORTS if you are building on Darwin/Mac OS X,
 130 # have DarwinPorts installed in /opt/local, but don't want GIT to

 134 #
 135 # Define NO_APPLE_COMMON_CRYPTO if you are building on Darwin/Mac OS X
 136 # and do not want to use Apple's CommonCrypto library.  This allows you
 137 # to provide your own OpenSSL library, for example from MacPorts.
 138 #
 139 # Define BLK_SHA1 environment variable to make use of the bundled
 140 # optimized C SHA1 routine.
 141 #
 142 # Define PPC_SHA1 environment variable when running make to make use of
 143 # a bundled SHA1 routine optimized for PowerPC.
 144 #
 145 # Define DC_SHA1 to unconditionally enable the collision-detecting sha1
 146 # algorithm. This is slower, but may detect attempted collision attacks.
 147 # Takes priority over other *_SHA1 knobs.
 148 #
 149 # Define SHA1_MAX_BLOCK_SIZE to limit the amount of data that will be hashed
 150 # in one call to the platform's SHA1_Update(). e.g. APPLE_COMMON_CRYPTO
 151 # wants 'SHA1_MAX_BLOCK_SIZE=1024L*1024L*1024L' defined.
 152 #
 153 # Define NEEDS_CRYPTO_WITH_SSL if you need -lcrypto when using -lssl (Darwin).

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

 191 #
 192 # Define NO_SETITIMER if you don't have setitimer()
 193 #
 194 # Define NO_STRUCT_ITIMERVAL if you don't have struct itimerval
 195 # This also implies NO_SETITIMER
 196 #
 197 # Define NO_FAST_WORKING_DIRECTORY if accessing objects in pack files is
 198 # generally faster on your platform than accessing the working directory.
 199 #
 200 # Define NO_TRUSTABLE_FILEMODE if your filesystem may claim to support
 201 # the executable mode bit, but doesn't really do so.
 202 #
 203 # Define NEEDS_MODE_TRANSLATION if your OS strays from the typical file type
 204 # bits in mode values (e.g. z/OS defines I_SFMT to 0xFF000000 as opposed to the
 205 # usual 0xF000).
 206 #
 207 # Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
 208 #
 209 # Define NO_UNIX_SOCKETS if your system does not offer unix sockets.
 210 #
 211 # Define NO_SOCKADDR_STORAGE if your platform does not have struct
 212 # sockaddr_storage.
 213 #

 220 #
 221 # Define NO_R_TO_GCC_LINKER if your gcc does not like "-R/path/lib"
 222 # that tells runtime paths to dynamic libraries;
 223 # "-Wl,-rpath=/path/lib" is used instead.
 224 #
 225 # Define NO_NORETURN if using buggy versions of gcc 4.6+ and profile feedback,
 226 # as the compiler can crash (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49299)
 227 #
 228 # Define USE_NSEC below if you want git to care about sub-second file mtimes
 229 # and ctimes. Note that you need recent glibc (at least 2.2.4) for this. On
 230 # Linux, kernel 2.6.11 or newer is required for reliable sub-second file times
 231 # on file systems with exactly 1 ns or 1 s resolution. If you intend to use Git
 232 # on other file systems (e.g. CEPH, CIFS, NTFS, UDF), don't enable USE_NSEC. See
 233 # Documentation/technical/racy-git.txt for details.
 234 #
 235 # Define USE_ST_TIMESPEC if your "struct stat" uses "st_ctimespec" instead of
 236 # "st_ctim"
 237 #
 238 # Define NO_NSEC if your "struct stat" does not have "st_ctim.tv_nsec"
 239 # available.  This automatically turns USE_NSEC off.
 240 #
 241 # Define USE_STDEV below if you want git to care about the underlying device
 242 # change being considered an inode change from the update-index perspective.
 243 #
 244 # Define NO_ST_BLOCKS_IN_STRUCT_STAT if your platform does not have st_blocks
 245 # field that counts the on-disk footprint in 512-byte blocks.
 246 #
 247 # Define DOCBOOK_XSL_172 if you want to format man pages with DocBook XSL v1.72
 248 # (not v1.73 or v1.71).
 249 #
 250 # Define ASCIIDOC_ROFF if your DocBook XSL does not escape raw roff directives
 251 # (versions 1.68.1 through v1.72).
 252 #
 253 # Define GNU_ROFF if your target system uses GNU groff.  This forces
 254 # apostrophes to be ASCII so that cut&pasting examples to the shell
 255 # will work.
 256 #
 257 # Define USE_ASCIIDOCTOR to use Asciidoctor instead of AsciiDoc to build the
 258 # documentation.
 259 #
 260 # Define ASCIIDOCTOR_EXTENSIONS_LAB to point to the location of the Asciidoctor
 261 # Extensions Lab if you have it available.
 262 #
 263 # Define PERL_PATH to the path of your Perl binary (usually /usr/bin/perl).
 264 #
 265 # Define NO_PERL_MAKEMAKER if you cannot use Makefiles generated by perl's
 266 # MakeMaker (e.g. using ActiveState under Cygwin).
 267 #
 268 # Define NO_PERL if you do not want Perl scripts or libraries at all.
 269 #
 270 # Define PYTHON_PATH to the path of your Python binary (often /usr/bin/python
 271 # but /usr/bin/python2.7 on some platforms).
 272 #
 273 # Define NO_PYTHON if you do not want Python scripts or libraries at all.
 274 #
 275 # Define NO_TCLTK if you do not want Tcl/Tk GUI.
 276 #
 277 # Define SANE_TEXT_GREP to "-a" if you use recent versions of GNU grep
 278 # and egrep that are pickier when their input contains non-ASCII data.
 279 #
 280 # The TCL_PATH variable governs the location of the Tcl interpreter
 281 # used to optimize git-gui for your system.  Only used if NO_TCLTK
 282 # is not set.  Defaults to the bare 'tclsh'.
 283 #
 284 # The TCLTK_PATH variable governs the location of the Tcl/Tk interpreter.
 285 # If not set it defaults to the bare 'wish'. If it is set to the empty
 286 # string then NO_TCLTK will be forced (this is used by configure script).
 287 #
 288 # Define INTERNAL_QSORT to use Git's implementation of qsort(), which
 289 # is a simplified version of the merge sort used in glibc. This is
 290 # recommended if Git triggers O(n^2) behavior in your platform's qsort().
 291 #
 292 # Define HAVE_ISO_QSORT_S if your platform provides a qsort_s() that's
 293 # compatible with the one described in C11 Annex K.
 294 #
 295 # Define UNRELIABLE_FSTAT if your system's fstat does not return the same
 296 # information on a not yet closed file that lstat would return for the same
 297 # file after it was closed.
 298 #
 299 # Define OBJECT_CREATION_USES_RENAMES if your operating systems has problems
 300 # when hardlinking a file to another name and unlinking the original file right
 301 # away (some NTFS drivers seem to zero the contents in that scenario).
 302 #
 303 # Define NO_CROSS_DIRECTORY_HARDLINKS if you plan to distribute the installed
 304 # programs as a tar, where bin/ and libexec/ might be on different file systems.
 305 #
 306 # Define NO_INSTALL_HARDLINKS if you prefer to use either symbolic links or
 307 # copies to install built-in git commands e.g. git-cat-file.
 308 #
 309 # Define USE_NED_ALLOCATOR if you want to replace the platforms default
 310 # memory allocators with the nedmalloc allocator written by Niall Douglas.
 311 #
 312 # Define OVERRIDE_STRDUP to override the libc version of strdup(3).
 313 # This is necessary when using a custom allocator in order to avoid
 314 # crashes due to allocation and free working on different 'heaps'.
 315 # It's defined automatically if USE_NED_ALLOCATOR is set.
 316 #
 317 # Define NO_REGEX if your C library lacks regex support with REG_STARTEND
 318 # feature.
 319 #
 320 # Define HAVE_DEV_TTY if your system can open /dev/tty to interact with the
 321 # user.
 322 #
 323 # Define GETTEXT_POISON if you are debugging the choice of strings marked
 324 # for translation.  In a GETTEXT_POISON build, you can turn all strings marked
 325 # for translation into gibberish by setting the GIT_GETTEXT_POISON variable
 326 # (to any value) in your environment.
 327 #
 328 # Define JSMIN to point to JavaScript minifier that functions as
 329 # a filter to have gitweb.js minified.
 330 #
 331 # Define CSSMIN to point to a CSS minifier in order to generate a minified
 332 # version of gitweb.css
 333 #
 334 # Define DEFAULT_PAGER to a sensible pager command (defaults to "less") if
 335 # you want to use something different.  The value will be interpreted by the
 336 # shell at runtime when it is used.
 337 #
 338 # Define DEFAULT_EDITOR to a sensible editor command (defaults to "vi") if you
 339 # want to use something different.  The value will be interpreted by the shell
 340 # if necessary when it is used.  Examples:
 341 #
 342 #   DEFAULT_EDITOR='~/bin/vi',
 343 #   DEFAULT_EDITOR='$GIT_FALLBACK_EDITOR',
 344 #   DEFAULT_EDITOR='"C:\Program Files\Vim\gvim.exe" --nofork'
 345 #
 346 # Define COMPUTE_HEADER_DEPENDENCIES to "yes" if you want dependencies on
 347 # header files to be automatically computed, to avoid rebuilding objects when
 348 # an unrelated header file changes.  Define it to "no" to use the hard-coded
 349 # dependency rules.  The default is "auto", which means to use computed header
 350 # dependencies if your compiler is detected to support it.
 351 #
 352 # Define NATIVE_CRLF if your platform uses CRLF for line endings.
 353 #
 354 # Define GIT_USER_AGENT if you want to change how git identifies itself during
 355 # network interactions.  The default is "git/$(GIT_VERSION)".
 356 #
 357 # Define DEFAULT_HELP_FORMAT to "man", "info" or "html"
 358 # (defaults to "man") if you want to have a different default when
 359 # "git help" is called without a parameter specifying the format.
 360 #
 361 # Define TEST_GIT_INDEX_VERSION to 2, 3 or 4 to run the test suite
 362 # with a different indexfile format version.  If it isn't set the index
 363 # file format used is index-v[23].
 364 #
 365 # Define GMTIME_UNRELIABLE_ERRORS if your gmtime() function does not
 366 # return NULL when it receives a bogus time_t.
 367 #
 368 # Define HAVE_CLOCK_GETTIME if your platform has clock_gettime.
 369 #
 370 # Define HAVE_CLOCK_MONOTONIC if your platform has CLOCK_MONOTONIC.
 371 #
 372 # Define NEEDS_LIBRT if your platform requires linking with librt (glibc version
 373 # before 2.17) for clock_gettime and CLOCK_MONOTONIC.
 374 #
 375 # Define USE_PARENS_AROUND_GETTEXT_N to "yes" if your compiler happily
 376 # compiles the following initialization:
 377 #
 378 #   static const char s[] = ("FOO");
 379 #
 380 # and define it to "no" if you need to remove the parentheses () around the
 381 # constant.  The default is "auto", which means to use parentheses if your
 382 # compiler is detected to support it.
 383 #
 384 # Define HAVE_BSD_SYSCTL if your platform has a BSD-compatible sysctl function.
 385 #
 386 # Define HAVE_GETDELIM if your system has the getdelim() function.
 387 #
 388 # Define PAGER_ENV to a SP separated VAR=VAL pairs to define
 389 # default environment variables to be passed when a pager is spawned, e.g.
 390 #
 391 #    PAGER_ENV = LESS=FRX LV=-c
 392 #

1734 ### Target-specific flags and dependencies
1735
1736 # The generic compilation pattern rule and automatically
1737 # computed header dependencies (falling back to a dependency on
1738 # LIB_H) are enough to describe how most targets should be built,
1739 # but some targets are special enough to need something a little
1740 # different.
1741 #
1742 # - When a source file "foo.c" #includes a generated header file,
1743 #   we need to list that dependency for the "foo.o" target.
1744 #
1745 #   We also list it from other targets that are built from foo.c
1746 #   like "foo.sp" and "foo.s", even though that is easy to forget
1747 #   to do because the generated header is already present around
1748 #   after a regular build attempt.
1749 #
1750 # - Some code depends on configuration kept in makefile
1751 #   variables. The target-specific variable EXTRA_CPPFLAGS can
1752 #   be used to convey that information to the C preprocessor
1753 #   using -D options.
1754 #
1755 #   The "foo.o" target should have a corresponding dependency on
1756 #   a file that changes when the value of the makefile variable
1757 #   changes.  For example, targets making use of the
1758 #   $(GIT_VERSION) variable depend on GIT-VERSION-FILE.
1759 #
1760 #   Technically the ".sp" and ".s" targets do not need this
1761 #   dependency because they are force-built, but they get the
1762 #   same dependency for consistency. This way, you do not have to
1763 #   know how each target is implemented. And it means the
1764 #   dependencies here will not need to change if the force-build
1765 #   details change some day.
