Makefile

   1 # The default target of this Makefile is...
   2 all:
   3
   4 # Define NO_OPENSSL environment variable if you do not have OpenSSL.
   5 # This also implies MOZILLA_SHA1.
   6 #
   7 # Define NO_CURL if you do not have curl installed.  git-http-pull and
   8 # git-http-push are not built, and you cannot use http:// and https://
   9 # transports.
  10 #
  11 # Define CURLDIR=/foo/bar if your curl header and library files are in
  12 # /foo/bar/include and /foo/bar/lib directories.
  13 #
  14 # Define NO_EXPAT if you do not have expat installed.  git-http-push is
  15 # not built, and you cannot push using http:// and https:// transports.
  16 #
  17 # Define NO_D_INO_IN_DIRENT if you don't have d_ino in your struct dirent.
  18 #
  19 # Define NO_D_TYPE_IN_DIRENT if your platform defines DT_UNKNOWN but lacks
  20 # d_type in struct dirent (latest Cygwin -- will be fixed soonish).
  21 #
  22 # Define NO_STRCASESTR if you don't have strcasestr.
  23 #
  24 # Define NO_STRLCPY if you don't have strlcpy.
  25 #
  26 # Define NO_SETENV if you don't have setenv in the C library.
  27 #
  28 # Define NO_SYMLINK_HEAD if you never want .git/HEAD to be a symbolic link.
  29 # Enable it on Windows.  By default, symrefs are still used.
  30 #
  31 # Define PPC_SHA1 environment variable when running make to make use of
  32 # a bundled SHA1 routine optimized for PowerPC.
  33 #
  34 # Define ARM_SHA1 environment variable when running make to make use of
  35 # a bundled SHA1 routine optimized for ARM.
  36 #
  37 # Define MOZILLA_SHA1 environment variable when running make to make use of
  38 # a bundled SHA1 routine coming from Mozilla. It is GPL'd and should be fast
  39 # on non-x86 architectures (e.g. PowerPC), while the OpenSSL version (default
  40 # choice) has very fast version optimized for i586.
  41 #
  42 # Define USE_PIC if you need the main git objects to be built with -fPIC
  43 # in order to build and link perl/Git.so.  x86-64 seems to need this.
  44 #
  45 # Define NEEDS_SSL_WITH_CRYPTO if you need -lcrypto with -lssl (Darwin).
  46 #
  47 # Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
  48 #
  49 # Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
  50 # Patrick Mauritz).
  51 #
  52 # Define NO_MMAP if you want to avoid mmap.
  53 #
  54 # Define WITH_OWN_SUBPROCESS_PY if you want to use with python 2.3.
  55 #
  56 # Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
  57 #
  58 # Define NO_SOCKADDR_STORAGE if your platform does not have struct
  59 # sockaddr_storage.
  60 #
  61 # Define NO_ICONV if your libc does not properly support iconv.
  62 #
  63 # Define NO_ACCURATE_DIFF if your diff program at least sometimes misses
  64 # a missing newline at the end of the file.
  65 #
  66 # Define NO_PYTHON if you want to loose all benefits of the recursive merge.
  67 #
  68 # Define COLLISION_CHECK below if you believe that SHA1's
  69 # 1461501637330902918203684832716283019655932542976 hashes do not give you
  70 # sufficient guarantee that no collisions between objects will ever happen.
  71 #
  72 # Define USE_NSEC below if you want git to care about sub-second file mtimes
  73 # and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
  74 # it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
  75 # randomly break unless your underlying filesystem supports those sub-second
  76 # times (my ext3 doesn't).
  77 #
  78 # Define USE_STDEV below if you want git to care about the underlying device
  79 # change being considered an inode change from the update-cache perspective.
