   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.
  19#
  20# Define ARM_SHA1 environment variable when running make to make use of
  21# a bundled SHA1 routine optimized for ARM.
  22#
  23# Define NEEDS_SSL_WITH_CRYPTO if you need -lcrypto with -lssl (Darwin).
  24#
  25# Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
  26#
  27# Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
  28# Patrick Mauritz).
  29#
  30# Define NO_MMAP if you want to avoid mmap.
  31#
  32# Define WITH_OWN_SUBPROCESS_PY if you want to use with python 2.3.
  33#
  34# Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
  35#
  36# Define COLLISION_CHECK below if you believe that SHA1's
  37# 1461501637330902918203684832716283019655932542976 hashes do not give you
  38# sufficient guarantee that no collisions between objects will ever happen.
  39
  40# DEFINES += -DCOLLISION_CHECK
  41
  42# Define USE_NSEC below if you want git to care about sub-second file mtimes
  43# and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
  44# it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
  45# randomly break unless your underlying filesystem supports those sub-second
  46# times (my ext3 doesn't).
  47
  48# DEFINES += -DUSE_NSEC
