CommitLineData
1# The default target of this Makefile is...
2all:
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.
