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 is not
10# built, and you cannot use http:// and https:// transports.
11#
12# Define CURLDIR=/foo/bar if your curl header and library files are in
13# /foo/bar/include and /foo/bar/lib directories.
14#
15# Define NO_STRCASESTR if you don't have strcasestr.
16#
17# Define PPC_SHA1 environment variable when running make to make use of
18# a bundled SHA1 routine optimized for PowerPC.
19#
20# Define ARM_SHA1 environment variable when running make to make use of
21# a bundled SHA1 routine optimized for ARM.
22#
23# Define NEEDS_SSL_WITH_CRYPTO if you need -lcrypto with -lssl (Darwin).
24#
25# Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
26#
27# Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
28# Patrick Mauritz).
29#
30# Define NO_MMAP if you want to avoid mmap.
31#
32# Define WITH_OWN_SUBPROCESS_PY if you want to use with python 2.3.
33#
34# Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
35#
36# Define COLLISION_CHECK below if you believe that SHA1's
37# 1461501637330902918203684832716283019655932542976 hashes do not give you
38# sufficient guarantee that no collisions between objects will ever happen.
39
40# DEFINES += -DCOLLISION_CHECK
41
42# Define USE_NSEC below if you want git to care about sub-second file mtimes
43# and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
44# it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
45# randomly break unless your underlying filesystem supports those sub-second
46# times (my ext3 doesn't).
