   1 # Define MOZILLA_SHA1 environment variable when running make to make use of
   2 # a bundled SHA1 routine coming from Mozilla. It is GPL'd and should be fast
   3 # on non-x86 architectures (e.g. PowerPC), while the OpenSSL version (default
   4 # choice) has very fast version optimized for i586.
   5 #
   6 # Define NO_OPENSSL environment variable if you do not have OpenSSL. You will
   7 # miss out git-rev-list --merge-order. This also implies MOZILLA_SHA1.
   8 #
   9 # Define NO_CURL if you do not have curl installed.  git-http-pull is not
  10 # built, and you cannot use http:// and https:// transports.
  11 #
  12 # Define CURLDIR=/foo/bar if your curl header and library files are in
  13 # /foo/bar/include and /foo/bar/lib directories.
  14 #
  15 # Define NO_STRCASESTR if you don't have strcasestr.
  16 #
  17 # Define PPC_SHA1 environment variable when running make to make use of
  18 # a bundled SHA1 routine optimized for PowerPC.

  21 # a bundled SHA1 routine optimized for ARM.

  30 # Define WITH_OWN_SUBPROCESS_PY if you want to use with python 2.3.
  31 #
  32 # Define COLLISION_CHECK below if you believe that SHA1's
  33 # 1461501637330902918203684832716283019655932542976 hashes do not give you
