   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. You will
  10 # miss out git-rev-list --merge-order. 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_STRCASESTR if you don't have strcasestr.
  23 #
  24 # Define PPC_SHA1 environment variable when running make to make use of
  25 # a bundled SHA1 routine optimized for PowerPC.
  26 #
  27 # Define ARM_SHA1 environment variable when running make to make use of
  28 # a bundled SHA1 routine optimized for ARM.
  29 #
  30 # Define NEEDS_SSL_WITH_CRYPTO if you need -lcrypto with -lssl (Darwin).
  31 #
  32 # Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
  33 #
  34 # Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
  35 # Patrick Mauritz).
  36 #
  37 # Define NO_MMAP if you want to avoid mmap.
  38 #
  39 # Define WITH_OWN_SUBPROCESS_PY if you want to use with python 2.3.
  40 #
  41 # Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
  42 #
  43 # Define COLLISION_CHECK below if you believe that SHA1's
  44 # 1461501637330902918203684832716283019655932542976 hashes do not give you
  45 # sufficient guarantee that no collisions between objects will ever happen.
  46
  47 # Define USE_NSEC below if you want git to care about sub-second file mtimes
  48 # and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
  49 # it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
  50 # randomly break unless your underlying filesystem supports those sub-second
  51 # times (my ext3 doesn't).
  52
  53 # Define USE_STDEV below if you want git to care about the underlying device
  54 # change being considered an inode change from the update-cache perspective.
