[git] / Makefile
1 # The default target of this Makefile is...
2 all::
3
4 # Define NO_OPENSSL environment variable if you do not have OpenSSL.
5 # This also implies MOZILLA_SHA1.
6 #
7 # Define NO_CURL if you do not have curl installed.  git-http-pull and
8 # git-http-push are not built, and you cannot use http:// and https://
9 # transports.
10 #
11 # Define CURLDIR=/foo/bar if your curl header and library files are in
12 # /foo/bar/include and /foo/bar/lib directories.
13 #
14 # Define NO_EXPAT if you do not have expat installed.  git-http-push is
15 # not built, and you cannot push using http:// and https:// transports.
16 #
17 # Define NO_D_INO_IN_DIRENT if you don't have d_ino in your struct dirent.
18 #
19 # Define NO_D_TYPE_IN_DIRENT if your platform defines DT_UNKNOWN but lacks
20 # d_type in struct dirent (latest Cygwin -- will be fixed soonish).
21 #
22 # Define NO_C99_FORMAT if your formatted IO functions (printf/scanf et.al.)
23 # do not support the 'size specifiers' introduced by C99, namely ll, hh,
24 # j, z, t. (representing long long int, char, intmax_t, size_t, ptrdiff_t).
25 # some C compilers supported these specifiers prior to C99 as an extension.
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_STRTOUMAX if you don't have strtoumax in the C library.
32 # If your compiler also does not support long long or does not have
33 # strtoull, define NO_STRTOULL.
34 #
35 # Define NO_SETENV if you don't have setenv in the C library.
36 #
37 # Define NO_SYMLINK_HEAD if you never want .git/HEAD to be a symbolic link.
38 # Enable it on Windows.  By default, symrefs are still used.
39 #
40 # Define NO_SVN_TESTS if you want to skip time-consuming SVN interoperability
41 # tests.  These tests take up a significant amount of the total test time
42 # but are not needed unless you plan to talk to SVN repos.
43 #
44 # Define NO_FINK if you are building on Darwin/Mac OS X, have Fink
45 # installed in /sw, but don't want GIT to link against any libraries
46 # installed there.  If defined you may specify your own (or Fink's)
47 # include directories and library directories by defining CFLAGS
48 # and LDFLAGS appropriately.
49 #
50 # Define NO_DARWIN_PORTS if you are building on Darwin/Mac OS X,
51 # have DarwinPorts installed in /opt/local, but don't want GIT to
52 # link against any libraries installed there.  If defined you may
53 # specify your own (or DarwinPort's) include directories and
54 # library directories by defining CFLAGS and LDFLAGS appropriately.
55 #
56 # Define PPC_SHA1 environment variable when running make to make use of
57 # a bundled SHA1 routine optimized for PowerPC.
58 #
59 # Define ARM_SHA1 environment variable when running make to make use of
60 # a bundled SHA1 routine optimized for ARM.
61 #
62 # Define MOZILLA_SHA1 environment variable when running make to make use of
63 # a bundled SHA1 routine coming from Mozilla. It is GPL'd and should be fast
64 # on non-x86 architectures (e.g. PowerPC), while the OpenSSL version (default
65 # choice) has very fast version optimized for i586.
66 #
67 # Define NEEDS_SSL_WITH_CRYPTO if you need -lcrypto with -lssl (Darwin).
68 #
69 # Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
70 #
71 # Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
72 # Patrick Mauritz).
73 #
74 # Define NO_MMAP if you want to avoid mmap.
75 #
76 # Define NO_PREAD if you have a problem with pread() system call (e.g.
77 # cygwin.dll before v1.5.22).
78 #
79 # Define NO_FAST_WORKING_DIRECTORY if accessing objects in pack files is
80 # generally faster on your platform than accessing the working directory.
81 #
82 # Define NO_TRUSTABLE_FILEMODE if your filesystem may claim to support
83 # the executable mode bit, but doesn't really do so.
84 #
85 # Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
86 #
87 # Define NO_SOCKADDR_STORAGE if your platform does not have struct
88 # sockaddr_storage.
89 #
90 # Define NO_ICONV if your libc does not properly support iconv.
91 #
92 # Define OLD_ICONV if your library has an old iconv(), where the second
93 # (input buffer pointer) parameter is declared with type (const char **).
94 #
95 # Define NO_R_TO_GCC if your gcc does not like "-R/path/lib" that
96 # tells runtime paths to dynamic libraries; "-Wl,-rpath=/path/lib"
97 # is used instead.
98 #
99 # Define USE_NSEC below if you want git to care about sub-second file mtimes
100 # and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
101 # it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
102 # randomly break unless your underlying filesystem supports those sub-second
103 # times (my ext3 doesn't).
104 #
105 # Define USE_STDEV below if you want git to care about the underlying device
106 # change being considered an inode change from the update-cache perspective.
107 #
108 # Define NO_PERL_MAKEMAKER if you cannot use Makefiles generated by perl's
109 # MakeMaker (e.g. using ActiveState under Cygwin).
