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_STRCASESTR if you don't have strcasestr.
  28 #
  29 # Define NO_STRLCPY if you don't have strlcpy.
  30 #
  31 # Define NO_SETENV if you don't have setenv in the C library.
  32 #
  33 # Define NO_SYMLINK_HEAD if you never want .git/HEAD to be a symbolic link.
  34 # Enable it on Windows.  By default, symrefs are still used.
  35 #
  36 # Define PPC_SHA1 environment variable when running make to make use of
  37 # a bundled SHA1 routine optimized for PowerPC.
  38 #
  39 # Define ARM_SHA1 environment variable when running make to make use of
  40 # a bundled SHA1 routine optimized for ARM.
  41 #
  42 # Define NEEDS_SSL_WITH_CRYPTO if you need -lcrypto with -lssl (Darwin).
  43 #
  44 # Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
  45 #
  46 # Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
  47 # Patrick Mauritz).
  48 #
  49 # Define NO_MMAP if you want to avoid mmap.
  50 #
  51 # Define WITH_OWN_SUBPROCESS_PY if you want to use with python 2.3.
  52 #
  53 # Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
  54 #
  55 # Define NO_SOCKADDR_STORAGE if your platform does not have struct
  56 # sockaddr_storage.
  57 #
  58 # Define NO_ICONV if your libc does not properly support iconv.
  59 #
  60 # Define NO_ACCURATE_DIFF if your diff program at least sometimes misses
  61 # a missing newline at the end of the file.
  62 #
  63 # Define NO_PYTHON if you want to loose all benefits of the recursive merge.
  64 #
  65 # Define COLLISION_CHECK below if you believe that SHA1's
  66 # 1461501637330902918203684832716283019655932542976 hashes do not give you
  67 # sufficient guarantee that no collisions between objects will ever happen.
  68
  69 # Define USE_NSEC below if you want git to care about sub-second file mtimes
  70 # and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
  71 # it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
  72 # randomly break unless your underlying filesystem supports those sub-second
  73 # times (my ext3 doesn't).
  74
  75 # Define USE_STDEV below if you want git to care about the underlying device
  76 # change being considered an inode change from the update-cache perspective.
