Makefileon commit diff.c: second war on whitespace. (448c3ef)
   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_C99_FORMAT if your formatted IO functions (printf/scanf et.al.)
  28# do not support the 'size specifiers' introduced by C99, namely ll, hh,
  29# j, z, t. (representing long long int, char, intmax_t, size_t, ptrdiff_t).
  30# some C compilers supported these specifiers prior to C99 as an extension.
  31#
  32# Define NO_STRCASESTR if you don't have strcasestr.
  33#
  34# Define NO_STRLCPY if you don't have strlcpy.
  35#
  36# Define NO_SETENV if you don't have setenv in the C library.
  37#
  38# Define NO_SYMLINK_HEAD if you never want .git/HEAD to be a symbolic link.
  39# Enable it on Windows.  By default, symrefs are still used.
  40#
  41# Define NO_SVN_TESTS if you want to skip time-consuming SVN interoperability
  42# tests.  These tests take up a significant amount of the total test time
  43# but are not needed unless you plan to talk to SVN repos.
  44#
  45# Define NO_FINK if you are building on Darwin/Mac OS X, have Fink
  46# installed in /sw, but don't want GIT to link against any libraries
  47# installed there.  If defined you may specify your own (or Fink's)
  48# include directories and library directories by defining CFLAGS
  49# and LDFLAGS appropriately.
  50#
  51# Define NO_DARWIN_PORTS if you are building on Darwin/Mac OS X,
  52# have DarwinPorts installed in /opt/local, but don't want GIT to
  53# link against any libraries installed there.  If defined you may
  54# specify your own (or DarwinPort's) include directories and
  55# library directories by defining CFLAGS and LDFLAGS appropriately.
  56#
  57# Define PPC_SHA1 environment variable when running make to make use of
  58# a bundled SHA1 routine optimized for PowerPC.
  59#
  60# Define ARM_SHA1 environment variable when running make to make use of
  61# a bundled SHA1 routine optimized for ARM.
  62#
  63# Define NEEDS_SSL_WITH_CRYPTO if you need -lcrypto with -lssl (Darwin).
  64#
  65# Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
  66#
  67# Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
  68# Patrick Mauritz).
  69#
  70# Define NO_MMAP if you want to avoid mmap.
  71#
  72# Define WITH_OWN_SUBPROCESS_PY if you want to use with python 2.3.
  73#
  74# Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
  75#
  76# Define NO_SOCKADDR_STORAGE if your platform does not have struct
  77# sockaddr_storage.
  78#
  79# Define NO_ICONV if your libc does not properly support iconv.
  80#
  81# Define NO_ACCURATE_DIFF if your diff program at least sometimes misses
  82# a missing newline at the end of the file.
  83#
  84# Define NO_PYTHON if you want to lose all benefits of the recursive merge.
  85#
  86# Define COLLISION_CHECK below if you believe that SHA1's
  87# 1461501637330902918203684832716283019655932542976 hashes do not give you
  88# sufficient guarantee that no collisions between objects will ever happen.
  89
  90# Define USE_NSEC below if you want git to care about sub-second file mtimes
  91# and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
  92# it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
  93# randomly break unless your underlying filesystem supports those sub-second
  94# times (my ext3 doesn't).
  95
  96# Define USE_STDEV below if you want git to care about the underlying device
  97# change being considered an inode change from the update-cache perspective.
