Makefileon commit xread/xwrite: do not worry about EINTR at calling sites. (1c15afb)
   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. You will
  10# miss out git-rev-list --merge-order. 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_STRCASESTR if you don't have strcasestr.
  23#
  24# Define NO_SETENV if you don't have setenv in the C library.
  25#
  26# Define PPC_SHA1 environment variable when running make to make use of
  27# a bundled SHA1 routine optimized for PowerPC.
  28#
  29# Define ARM_SHA1 environment variable when running make to make use of
  30# a bundled SHA1 routine optimized for ARM.
  31#
  32# Define NEEDS_SSL_WITH_CRYPTO if you need -lcrypto with -lssl (Darwin).
  33#
  34# Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
  35#
  36# Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
  37# Patrick Mauritz).
  38#
  39# Define NO_MMAP if you want to avoid mmap.
  40#
  41# Define WITH_OWN_SUBPROCESS_PY if you want to use with python 2.3.
  42#
  43# Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
  44#
  45# Define COLLISION_CHECK below if you believe that SHA1's
  46# 1461501637330902918203684832716283019655932542976 hashes do not give you
  47# sufficient guarantee that no collisions between objects will ever happen.
  48
  49# Define USE_NSEC below if you want git to care about sub-second file mtimes
  50# and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
  51# it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
  52# randomly break unless your underlying filesystem supports those sub-second
  53# times (my ext3 doesn't).
  54
  55# Define USE_STDEV below if you want git to care about the underlying device
  56# change being considered an inode change from the update-cache perspective.
