1# The default target of this Makefile is...
2all:
3
5bdac8b3
PB
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.
bdd4da59 8#
765ac8ec
LT
9# Define NO_OPENSSL environment variable if you do not have OpenSSL.
10# This also implies MOZILLA_SHA1.
2cb45e95 11#
58e60dd2
NH
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.
b2c0bd65 15#
6d9bbc50
PM
16# Define CURLDIR=/foo/bar if your curl header and library files are in
17# /foo/bar/include and /foo/bar/lib directories.
18#
58e60dd2
NH
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#
35a730f0
JH
22# Define NO_D_INO_IN_DIRENT if you don't have d_ino in your struct dirent.
23#
63be37b0
JH
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#
579d1fbf
RJ
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).
465e649d 30# some C compilers supported these specifiers prior to C99 as an extension.
579d1fbf 31#
ef34af24

32# Define NO_STRCASESTR if you don't have strcasestr.

36# Define NO_SETENV if you don't have setenv in the C library.
37#
9f0bb90d
JH
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.
2fabd217 40#
02853588 41# Define NO_SVN_TESTS if you want to skip time-consuming SVN interoperability
60d02ccc
EW
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#
8eb38cad
SP
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.

60# Define ARM_SHA1 environment variable when running make to make use of
61# a bundled SHA1 routine optimized for ARM.

597c9cc5 63# Define NEEDS_SSL_WITH_CRYPTO if you need -lcrypto with -lssl (Darwin).
f0ebff0d 64#
597c9cc5 65# Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
f0ebff0d

68# Patrick Mauritz).

82# a missing newline at the end of the file.

addf88e4 84# Define NO_PYTHON if you want to lose all benefits of the recursive merge.
abb7c7b3 85#
5bdac8b3
PB
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
5bdac8b3
PB
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
5bdac8b3
PB
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.
