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