   1# The default target of this Makefile is...
   2all:
   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.
