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_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 NO_SVN_TESTS if you want to skip time-consuming SVN interoperability
37 # tests.  These tests take up a significant amount of the total test time
38 # but are not needed unless you plan to talk to SVN repos.
39 #
40 # Define NO_FINK if you are building on Darwin/Mac OS X, have Fink
41 # installed in /sw, but don't want GIT to link against any libraries
42 # installed there.  If defined you may specify your own (or Fink's)
43 # include directories and library directories by defining CFLAGS
44 # and LDFLAGS appropriately.
45 #
46 # Define NO_DARWIN_PORTS if you are building on Darwin/Mac OS X,
47 # have DarwinPorts installed in /opt/local, but don't want GIT to
48 # link against any libraries installed there.  If defined you may
49 # specify your own (or DarwinPort's) include directories and
50 # library directories by defining CFLAGS and LDFLAGS appropriately.
51 #
52 # Define PPC_SHA1 environment variable when running make to make use of
53 # a bundled SHA1 routine optimized for PowerPC.
54 #
55 # Define ARM_SHA1 environment variable when running make to make use of
56 # a bundled SHA1 routine optimized for ARM.
57 #
58 # Define MOZILLA_SHA1 environment variable when running make to make use of
59 # a bundled SHA1 routine coming from Mozilla. It is GPL'd and should be fast
60 # on non-x86 architectures (e.g. PowerPC), while the OpenSSL version (default
61 # choice) has very fast version optimized for i586.
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 NO_FAST_WORKING_DIRECTORY if accessing objects in pack files is
73 # generally faster on your platform than accessing the working directory.
74 #
75 # Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
76 #
77 # Define NO_SOCKADDR_STORAGE if your platform does not have struct
78 # sockaddr_storage.
79 #
80 # Define NO_ICONV if your libc does not properly support iconv.
81 #
82 # Define NO_R_TO_GCC if your gcc does not like "-R/path/lib" that
83 # tells runtime paths to dynamic libraries; "-Wl,-rpath=/path/lib"
84 # is used instead.
85 #
86 # Define USE_NSEC below if you want git to care about sub-second file mtimes
87 # and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
88 # it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
89 # randomly break unless your underlying filesystem supports those sub-second
90 # times (my ext3 doesn't).
91 #
92 # Define USE_STDEV below if you want git to care about the underlying device
93 # change being considered an inode change from the update-cache perspective.
94 #
95 # Define NO_PERL_MAKEMAKER if you cannot use Makefiles generated by perl's
96 # MakeMaker (e.g. using ActiveState under Cygwin).
