Makefile: do not assume lack of IPV6 means no sockaddr_storage.
[git/git.git] / Makefile
1 # The default target of this Makefile is...
2 all:
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 USE_SYMLINK_HEAD if you want .git/HEAD to be a symbolic link.
27 # Don't enable it on Windows.
28 #
29 # Define PPC_SHA1 environment variable when running make to make use of
30 # a bundled SHA1 routine optimized for PowerPC.
31 #
32 # Define ARM_SHA1 environment variable when running make to make use of
33 # a bundled SHA1 routine optimized for ARM.
34 #
35 # Define NEEDS_SSL_WITH_CRYPTO if you need -lcrypto with -lssl (Darwin).
36 #
37 # Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
38 #
39 # Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
40 # Patrick Mauritz).
41 #
42 # Define NO_MMAP if you want to avoid mmap.
43 #
44 # Define WITH_OWN_SUBPROCESS_PY if you want to use with python 2.3.
45 #
46 # Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
47 #
48 # Define NO_SOCKADDR_STORAGE if your platform does not have struct
49 # sockaddr_storage.
50 #
51 # Define COLLISION_CHECK below if you believe that SHA1's
52 # 1461501637330902918203684832716283019655932542976 hashes do not give you
53 # sufficient guarantee that no collisions between objects will ever happen.
54
55 # Define USE_NSEC below if you want git to care about sub-second file mtimes
56 # and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
57 # it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
58 # randomly break unless your underlying filesystem supports those sub-second
59 # times (my ext3 doesn't).
60
61 # Define USE_STDEV below if you want git to care about the underlying device
62 # change being considered an inode change from the update-cache perspective.
