Makefile

   1 # The default target of this Makefile is...
   2 all:
   3
   4 # Define MOZILLA_SHA1 environment variable when running make to make use of
   5 # a bundled SHA1 routine coming from Mozilla. It is GPL'd and should be fast
   6 # on non-x86 architectures (e.g. PowerPC), while the OpenSSL version (default
   7 # choice) has very fast version optimized for i586.
   8 #
   9 # Define NO_OPENSSL environment variable if you do not have OpenSSL.
  10 # This also implies MOZILLA_SHA1.
  11 #
  12 # Define NO_CURL if you do not have curl installed.  git-http-pull and
  13 # git-http-push are not built, and you cannot use http:// and https://
  14 # transports.
  15 #
  16 # Define CURLDIR=/foo/bar if your curl header and library files are in
  17 # /foo/bar/include and /foo/bar/lib directories.
  18 #
  19 # Define NO_EXPAT if you do not have expat installed.  git-http-push is
  20 # not built, and you cannot push using http:// and https:// transports.
  21 #
  22 # Define NO_D_INO_IN_DIRENT if you don't have d_ino in your struct dirent.
  23 #
  24 # Define NO_D_TYPE_IN_DIRENT if your platform defines DT_UNKNOWN but lacks
  25 # d_type in struct dirent (latest Cygwin -- will be fixed soonish).
  26 #
  27 # Define NO_C99_FORMAT if your formatted IO functions (printf/scanf et.al.)
  28 # do not support the 'size specifiers' introduced by C99, namely ll, hh,
  29 # j, z, t. (representing long long int, char, intmax_t, size_t, ptrdiff_t).
  30 # some c compilers supported these specifiers prior to C99 as an extension.
  31 #
  32 # Define NO_STRCASESTR if you don't have strcasestr.
  33 #
  34 # Define NO_STRLCPY if you don't have strlcpy.
  35 #
  36 # Define NO_SETENV if you don't have setenv in the C library.
  37 #
  38 # Define NO_SYMLINK_HEAD if you never want .git/HEAD to be a symbolic link.
  39 # Enable it on Windows.  By default, symrefs are still used.
  40 #
  41 # Define NO_SVN_TESTS if you want to skip time-consuming SVN interoperability
  42 # tests.  These tests take up a significant amount of the total test time
  43 # but are not needed unless you plan to talk to SVN repos.
  44 #
  45 # Define NO_FINK if you are building on Darwin/Mac OS X, have Fink
  46 # installed in /sw, but don't want GIT to link against any libraries
  47 # installed there.  If defined you may specify your own (or Fink's)
  48 # include directories and library directories by defining CFLAGS
  49 # and LDFLAGS appropriately.
  50 #
  51 # Define NO_DARWIN_PORTS if you are building on Darwin/Mac OS X,
  52 # have DarwinPorts installed in /opt/local, but don't want GIT to
  53 # link against any libraries installed there.  If defined you may
  54 # specify your own (or DarwinPort's) include directories and
  55 # library directories by defining CFLAGS and LDFLAGS appropriately.
  56 #
  57 # Define PPC_SHA1 environment variable when running make to make use of
  58 # a bundled SHA1 routine optimized for PowerPC.
  59 #
  60 # Define ARM_SHA1 environment variable when running make to make use of
  61 # a bundled SHA1 routine optimized for ARM.
  62 #
  63 # Define NEEDS_SSL_WITH_CRYPTO if you need -lcrypto with -lssl (Darwin).
  64 #
  65 # Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
  66 #
  67 # Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
  68 # Patrick Mauritz).
  69 #
  70 # Define NO_MMAP if you want to avoid mmap.
  71 #
  72 # Define WITH_OWN_SUBPROCESS_PY if you want to use with python 2.3.
  73 #
  74 # Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
  75 #
  76 # Define NO_SOCKADDR_STORAGE if your platform does not have struct
  77 # sockaddr_storage.
  78 #
  79 # Define NO_ICONV if your libc does not properly support iconv.
  80 #
  81 # Define NO_ACCURATE_DIFF if your diff program at least sometimes misses
  82 # a missing newline at the end of the file.
  83 #
  84 # Define NO_PYTHON if you want to lose all benefits of the recursive merge.
  85 #
  86 # Define COLLISION_CHECK below if you believe that SHA1's
  87 # 1461501637330902918203684832716283019655932542976 hashes do not give you
  88 # sufficient guarantee that no collisions between objects will ever happen.
  89
  90 # Define USE_NSEC below if you want git to care about sub-second file mtimes
  91 # and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
  92 # it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
  93 # randomly break unless your underlying filesystem supports those sub-second
  94 # times (my ext3 doesn't).
  95
  96 # Define USE_STDEV below if you want git to care about the underlying device
  97 # change being considered an inode change from the update-cache perspective.
