Fixed git:// IPv4 address problem when compiled with -DNO_IPV6.
[git] / Makefile
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 and
10 # git-http-push are not built, and you cannot use http:// and https://
11 # transports.
12 #
13 # Define CURLDIR=/foo/bar if your curl header and library files are in
14 # /foo/bar/include and /foo/bar/lib directories.
15 #
16 # Define NO_EXPAT if you do not have expat installed.  git-http-push is
17 # not built, and you cannot push using http:// and https:// transports.
18 #
19 # Define NO_STRCASESTR if you don't have strcasestr.
20 #
21 # Define PPC_SHA1 environment variable when running make to make use of
22 # a bundled SHA1 routine optimized for PowerPC.
23 #
24 # Define ARM_SHA1 environment variable when running make to make use of
25 # a bundled SHA1 routine optimized for ARM.
26 #
27 # Define NEEDS_SSL_WITH_CRYPTO if you need -lcrypto with -lssl (Darwin).
28 #
29 # Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
30 #
31 # Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
32 # Patrick Mauritz).
33 #
34 # Define NO_MMAP if you want to avoid mmap.
35 #
36 # Define WITH_OWN_SUBPROCESS_PY if you want to use with python 2.3.
37 #
38 # Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
39 #
40 # Define COLLISION_CHECK below if you believe that SHA1's
41 # 1461501637330902918203684832716283019655932542976 hashes do not give you
42 # sufficient guarantee that no collisions between objects will ever happen.
43
44 # Define USE_NSEC below if you want git to care about sub-second file mtimes
45 # and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
46 # it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
47 # randomly break unless your underlying filesystem supports those sub-second
48 # times (my ext3 doesn't).
49
50 # Define USE_STDEV below if you want git to care about the underlying device
51 # change being considered an inode change from the update-cache perspective.
