Makefile

   1 # The default target of this Makefile is...
   2 all:
   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_C99_FORMAT if your formatted IO functions (printf/scanf et.al.)
  23 # do not support the 'size specifiers' introduced by C99, namely ll, hh,
  24 # j, z, t. (representing long long int, char, intmax_t, size_t, ptrdiff_t).
  25 # some C compilers supported these specifiers prior to C99 as an extension.
  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 MOZILLA_SHA1 environment variable when running make to make use of
  59 # a bundled SHA1 routine coming from Mozilla. It is GPL'd and should be fast
  60 # on non-x86 architectures (e.g. PowerPC), while the OpenSSL version (default
  61 # choice) has very fast version optimized for i586.
  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 COLLISION_CHECK below if you believe that SHA1's
  85 # 1461501637330902918203684832716283019655932542976 hashes do not give you
  86 # sufficient guarantee that no collisions between objects will ever happen.
  87 #
  88 # Define USE_NSEC below if you want git to care about sub-second file mtimes
  89 # and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
  90 # it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
  91 # randomly break unless your underlying filesystem supports those sub-second
  92 # times (my ext3 doesn't).
  93 #
  94 # Define USE_STDEV below if you want git to care about the underlying device
  95 # change being considered an inode change from the update-cache perspective.
