Fix minor formatting issue in man page for git-mergetool
[git] / Makefile
1 # The default target of this Makefile is...
2 all::
3
4 # Define V=1 to have a more verbose compile.
5 #
6 # Define NO_OPENSSL environment variable if you do not have OpenSSL.
7 # 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_D_INO_IN_DIRENT if you don't have d_ino in your struct dirent.
20 #
21 # Define NO_D_TYPE_IN_DIRENT if your platform defines DT_UNKNOWN but lacks
22 # d_type in struct dirent (latest Cygwin -- will be fixed soonish).
23 #
24 # Define NO_C99_FORMAT if your formatted IO functions (printf/scanf et.al.)
25 # do not support the 'size specifiers' introduced by C99, namely ll, hh,
26 # j, z, t. (representing long long int, char, intmax_t, size_t, ptrdiff_t).
27 # some C compilers supported these specifiers prior to C99 as an extension.
28 #
29 # Define NO_STRCASESTR if you don't have strcasestr.
30 #
31 # Define NO_STRLCPY if you don't have strlcpy.
32 #
33 # Define NO_STRTOUMAX if you don't have strtoumax in the C library.
34 # If your compiler also does not support long long or does not have
35 # strtoull, define NO_STRTOULL.
36 #
37 # Define NO_SETENV if you don't have setenv in the C library.
38 #
39 # Define NO_SYMLINK_HEAD if you never want .git/HEAD to be a symbolic link.
40 # Enable it on Windows.  By default, symrefs are still used.
41 #
42 # Define NO_SVN_TESTS if you want to skip time-consuming SVN interoperability
43 # tests.  These tests take up a significant amount of the total test time
44 # but are not needed unless you plan to talk to SVN repos.
45 #
46 # Define NO_FINK if you are building on Darwin/Mac OS X, have Fink
47 # installed in /sw, but don't want GIT to link against any libraries
48 # installed there.  If defined you may specify your own (or Fink's)
49 # include directories and library directories by defining CFLAGS
50 # and LDFLAGS appropriately.
51 #
52 # Define NO_DARWIN_PORTS if you are building on Darwin/Mac OS X,
53 # have DarwinPorts installed in /opt/local, but don't want GIT to
54 # link against any libraries installed there.  If defined you may
55 # specify your own (or DarwinPort's) include directories and
56 # library directories by defining CFLAGS and LDFLAGS appropriately.
57 #
58 # Define PPC_SHA1 environment variable when running make to make use of
59 # a bundled SHA1 routine optimized for PowerPC.
60 #
61 # Define ARM_SHA1 environment variable when running make to make use of
62 # a bundled SHA1 routine optimized for ARM.
63 #
64 # Define MOZILLA_SHA1 environment variable when running make to make use of
65 # a bundled SHA1 routine coming from Mozilla. It is GPL'd and should be fast
66 # on non-x86 architectures (e.g. PowerPC), while the OpenSSL version (default
67 # choice) has very fast version optimized for i586.
68 #
69 # Define NEEDS_SSL_WITH_CRYPTO if you need -lcrypto with -lssl (Darwin).
70 #
71 # Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
72 #
73 # Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
74 # Patrick Mauritz).
75 #
76 # Define NO_MMAP if you want to avoid mmap.
77 #
78 # Define NO_PREAD if you have a problem with pread() system call (e.g.
79 # cygwin.dll before v1.5.22).
80 #
81 # Define NO_FAST_WORKING_DIRECTORY if accessing objects in pack files is
82 # generally faster on your platform than accessing the working directory.
83 #
84 # Define NO_TRUSTABLE_FILEMODE if your filesystem may claim to support
85 # the executable mode bit, but doesn't really do so.
86 #
87 # Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
88 #
89 # Define NO_SOCKADDR_STORAGE if your platform does not have struct
90 # sockaddr_storage.
91 #
92 # Define NO_ICONV if your libc does not properly support iconv.
93 #
94 # Define OLD_ICONV if your library has an old iconv(), where the second
95 # (input buffer pointer) parameter is declared with type (const char **).
96 #
97 # Define NO_R_TO_GCC if your gcc does not like "-R/path/lib" that
98 # tells runtime paths to dynamic libraries; "-Wl,-rpath=/path/lib"
99 # is used instead.
100 #
101 # Define USE_NSEC below if you want git to care about sub-second file mtimes
102 # and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
103 # it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
104 # randomly break unless your underlying filesystem supports those sub-second
105 # times (my ext3 doesn't).
106 #
107 # Define USE_STDEV below if you want git to care about the underlying device
108 # change being considered an inode change from the update-cache perspective.
109 #
110 # Define NO_PERL_MAKEMAKER if you cannot use Makefiles generated by perl's
111 # MakeMaker (e.g. using ActiveState under Cygwin).
