Makefileon commit Merge branch 'ff/c99' (e94528a)
   1# The default target of this Makefile is...
   2all:
   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.
  10# 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_D_INO_IN_DIRENT if you don't have d_ino in your struct dirent.
  23#
  24# Define NO_D_TYPE_IN_DIRENT if your platform defines DT_UNKNOWN but lacks
  25# d_type in struct dirent (latest Cygwin -- will be fixed soonish).
  26#
  27# Define NO_STRCASESTR if you don't have strcasestr.
  28#
  29# Define NO_SETENV if you don't have setenv in the C library.
  30#
  31# Define NO_SYMLINK_HEAD if you never want .git/HEAD to be a symbolic link.
  32# Enable it on Windows.  By default, symrefs are still used.
  33#
  34# Define PPC_SHA1 environment variable when running make to make use of
  35# a bundled SHA1 routine optimized for PowerPC.
  36#
  37# Define ARM_SHA1 environment variable when running make to make use of
  38# a bundled SHA1 routine optimized for ARM.
  39#
  40# Define NEEDS_SSL_WITH_CRYPTO if you need -lcrypto with -lssl (Darwin).
  41#
  42# Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
  43#
  44# Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
  45# Patrick Mauritz).
  46#
  47# Define NO_MMAP if you want to avoid mmap.
  48#
  49# Define WITH_OWN_SUBPROCESS_PY if you want to use with python 2.3.
  50#
  51# Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
  52#
  53# Define NO_SOCKADDR_STORAGE if your platform does not have struct
  54# sockaddr_storage.
  55#
  56# Define NO_ICONV if your libc does not properly support iconv.
  57#
  58# Define NO_ACCURATE_DIFF if your diff program at least sometimes misses
  59# a missing newline at the end of the file.
  60#
  61# Define NO_PYTHON if you want to loose all benefits of the recursive merge.
  62#
  63# Define COLLISION_CHECK below if you believe that SHA1's
  64# 1461501637330902918203684832716283019655932542976 hashes do not give you
  65# sufficient guarantee that no collisions between objects will ever happen.
  66
  67# Define USE_NSEC below if you want git to care about sub-second file mtimes
  68# and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
  69# it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
  70# randomly break unless your underlying filesystem supports those sub-second
  71# times (my ext3 doesn't).
  72
  73# Define USE_STDEV below if you want git to care about the underlying device
  74# change being considered an inode change from the update-cache perspective.
