Make git-unpack-objects a builtin
[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.
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_C99_FORMAT if your formatted IO functions (printf/scanf et.al.)
28 # do not support the 'size specifiers' introduced by C99, namely ll, hh,
29 # j, z, t. (representing long long int, char, intmax_t, size_t, ptrdiff_t).
30 # some c compilers supported these specifiers prior to C99 as an extension.
31 #
32 # Define NO_STRCASESTR if you don't have strcasestr.
33 #
34 # Define NO_STRLCPY if you don't have strlcpy.
35 #
36 # Define NO_SETENV if you don't have setenv in the C library.
37 #
38 # Define NO_SYMLINK_HEAD if you never want .git/HEAD to be a symbolic link.
39 # Enable it on Windows.  By default, symrefs are still used.
40 #
41 # Define NO_SVN_TESTS if you want to skip time-consuming SVN interoperability
42 # tests.  These tests take up a significant amount of the total test time
43 # but are not needed unless you plan to talk to SVN repos.
44 #
45 # Define NO_FINK if you are building on Darwin/Mac OS X, have Fink
46 # installed in /sw, but don't want GIT to link against any libraries
47 # installed there.  If defined you may specify your own (or Fink's)
48 # include directories and library directories by defining CFLAGS
49 # and LDFLAGS appropriately.
50 #
51 # Define NO_DARWIN_PORTS if you are building on Darwin/Mac OS X,
52 # have DarwinPorts installed in /opt/local, but don't want GIT to
53 # link against any libraries installed there.  If defined you may
54 # specify your own (or DarwinPort's) include directories and
55 # library directories by defining CFLAGS and LDFLAGS appropriately.
56 #
57 # Define PPC_SHA1 environment variable when running make to make use of
58 # a bundled SHA1 routine optimized for PowerPC.
59 #
60 # Define ARM_SHA1 environment variable when running make to make use of
61 # a bundled SHA1 routine optimized for ARM.
62 #
63 # Define NEEDS_SSL_WITH_CRYPTO if you need -lcrypto with -lssl (Darwin).
64 #
65 # Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
66 #
67 # Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
68 # Patrick Mauritz).
69 #
70 # Define NO_MMAP if you want to avoid mmap.
71 #
72 # Define WITH_OWN_SUBPROCESS_PY if you want to use with python 2.3.
73 #
74 # Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
75 #
76 # Define NO_SOCKADDR_STORAGE if your platform does not have struct
77 # sockaddr_storage.
78 #
79 # Define NO_ICONV if your libc does not properly support iconv.
80 #
81 # Define NO_ACCURATE_DIFF if your diff program at least sometimes misses
82 # a missing newline at the end of the file.
83 #
84 # Define NO_PYTHON if you want to lose all benefits of the recursive merge.
85 #
86 # Define COLLISION_CHECK below if you believe that SHA1's
87 # 1461501637330902918203684832716283019655932542976 hashes do not give you
88 # sufficient guarantee that no collisions between objects will ever happen.
89
90 # Define USE_NSEC below if you want git to care about sub-second file mtimes
91 # and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
92 # it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
93 # randomly break unless your underlying filesystem supports those sub-second
94 # times (my ext3 doesn't).
95
96 # Define USE_STDEV below if you want git to care about the underlying device
97 # change being considered an inode change from the update-cache perspective.
