1# Define MOZILLA_SHA1 environment variable when running make to make use of
2# a bundled SHA1 routine coming from Mozilla. It is GPL'd and should be fast
3# on non-x86 architectures (e.g. PowerPC), while the OpenSSL version (default
4# choice) has very fast version optimized for i586.
5#
6# Define NO_OPENSSL environment variable if you do not have OpenSSL. You will
7# miss out git-rev-list --merge-order. 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_STRCASESTR if you don't have strcasestr.
20#
21# Define PPC_SHA1 environment variable when running make to make use of
22# a bundled SHA1 routine optimized for PowerPC.
23#
24# Define ARM_SHA1 environment variable when running make to make use of
25# a bundled SHA1 routine optimized for ARM.
26#
27# Define NEEDS_SSL_WITH_CRYPTO if you need -lcrypto with -lssl (Darwin).
28#
29# Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
30#
31# Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
32# Patrick Mauritz).
33#
34# Define NO_MMAP if you want to avoid mmap.
35#
36# Define WITH_OWN_SUBPROCESS_PY if you want to use with python 2.3.
37#
38# Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
39#
40# Define COLLISION_CHECK below if you believe that SHA1's
41# 1461501637330902918203684832716283019655932542976 hashes do not give you
42# sufficient guarantee that no collisions between objects will ever happen.
43
44# Define USE_NSEC below if you want git to care about sub-second file mtimes
45# and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
46# it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
47# randomly break unless your underlying filesystem supports those sub-second
48# times (my ext3 doesn't).
49
50# Define USE_STDEV below if you want git to care about the underlying device
51# change being considered an inode change from the update-cache perspective.
