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.
10 # 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_D_INO_IN_DIRENT if you don't have d_ino in your struct dirent.
23 #
24 # Define NO_D_TYPE_IN_DIRENT if your platform defines DT_UNKNOWN but lacks
25 # d_type in struct dirent (latest Cygwin -- will be fixed soonish).
26 #
27 # Define NO_STRCASESTR if you don't have strcasestr.
28 #
29 # Define NO_STRLCPY if you don't have strlcpy.
30 #
31 # Define NO_SETENV if you don't have setenv in the C library.
32 #
33 # Define NO_SYMLINK_HEAD if you never want .git/HEAD to be a symbolic link.
34 # Enable it on Windows.  By default, symrefs are still used.
35 #
36 # Define PPC_SHA1 environment variable when running make to make use of
37 # a bundled SHA1 routine optimized for PowerPC.
38 #
39 # Define ARM_SHA1 environment variable when running make to make use of
40 # a bundled SHA1 routine optimized for ARM.
41 #
42 # Define NEEDS_SSL_WITH_CRYPTO if you need -lcrypto with -lssl (Darwin).
43 #
44 # Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
45 #
46 # Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
47 # Patrick Mauritz).
48 #
49 # Define NO_MMAP if you want to avoid mmap.
50 #
51 # Define WITH_OWN_SUBPROCESS_PY if you want to use with python 2.3.
52 #
53 # Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
54 #
55 # Define NO_SOCKADDR_STORAGE if your platform does not have struct
56 # sockaddr_storage.
57 #
58 # Define NO_ICONV if your libc does not properly support iconv.
59 #
60 # Define NO_ACCURATE_DIFF if your diff program at least sometimes misses
61 # a missing newline at the end of the file.
62 #
63 # Define NO_PYTHON if you want to loose all benefits of the recursive merge.
64 #
65 # Define COLLISION_CHECK below if you believe that SHA1's
66 # 1461501637330902918203684832716283019655932542976 hashes do not give you
67 # sufficient guarantee that no collisions between objects will ever happen.
68
69 # Define USE_NSEC below if you want git to care about sub-second file mtimes
70 # and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
71 # it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
72 # randomly break unless your underlying filesystem supports those sub-second
73 # times (my ext3 doesn't).
74
75 # Define USE_STDEV below if you want git to care about the underlying device
76 # change being considered an inode change from the update-cache perspective.
