1 # Define MOZILLA_SHA1 environment variable when running make to make use of
2 # a bundled SHA1 routine coming from Mozilla. It is GPL'd and should be fast
3 # on non-x86 architectures (e.g. PowerPC), while the OpenSSL version (default
4 # choice) has very fast version optimized for i586.
5 #
6 # Define NO_OPENSSL environment variable if you do not have OpenSSL. You will
7 # miss out git-rev-list --merge-order. This also implies MOZILLA_SHA1.
8 #
9 # Define NO_CURL if you do not have curl installed.  git-http-pull is not
10 # built, and you cannot use http:// and https:// transports.
11 #
12 # Define CURLDIR=/foo/bar if your curl header and library files are in
13 # /foo/bar/include and /foo/bar/lib directories.
14 #
15 # Define NO_STRCASESTR if you don't have strcasestr.
16 #
17 # Define PPC_SHA1 environment variable when running make to make use of
18 # a bundled SHA1 routine optimized for PowerPC.
19 #
20 # Define ARM_SHA1 environment variable when running make to make use of
21 # a bundled SHA1 routine optimized for ARM.
22 #
23 # Define NEEDS_SSL_WITH_CRYPTO if you need -lcrypto with -lssl (Darwin).
24 #
25 # Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
26 #
27 # Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
28 # Patrick Mauritz).
29 #
30 # Define NO_MMAP if you want to avoid mmap.
31 #
32 # Define WITH_OWN_SUBPROCESS_PY if you want to use with python 2.3.
33 #
34 # Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
35 #
36 # Define COLLISION_CHECK below if you believe that SHA1's
37 # 1461501637330902918203684832716283019655932542976 hashes do not give you
38 # sufficient guarantee that no collisions between objects will ever happen.
39
40 # Define USE_NSEC below if you want git to care about sub-second file mtimes
41 # and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
42 # it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
43 # randomly break unless your underlying filesystem supports those sub-second
44 # times (my ext3 doesn't).
45
46 # Define USE_STDEV below if you want git to care about the underlying device
47 # change being considered an inode change from the update-cache perspective.
