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 PPC_SHA1 environment variable when running make to make use of
13 # a bundled SHA1 routine optimized for PowerPC.
14 #
15 # Define NEEDS_SSL_WITH_CRYPTO if you need -lcrypto with -lssl (Darwin).
16 #
17 # Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
18 #
19 # Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
20 # Patrick Mauritz).
21 #
22 # Define NO_GETDOMAINNAME if your library lack it (SunOS, Patrick Mauritz).
23 #
24 # Define COLLISION_CHECK below if you believe that SHA1's
25 # 1461501637330902918203684832716283019655932542976 hashes do not give you
26 # sufficient guarantee that no collisions between objects will ever happen.
27
28 # DEFINES += -DCOLLISION_CHECK
29
30 # Define USE_NSEC below if you want git to care about sub-second file mtimes
31 # and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
32 # it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
33 # randomly break unless your underlying filesystem supports those sub-second
34 # times (my ext3 doesn't).
35
36 # DEFINES += -DUSE_NSEC
37
38 # Define USE_STDEV below if you want git to care about the underlying device
39 # change being considered an inode change from the update-cache perspective.
