- # Define MOZILLA_SHA1 environment variable when running make to make use of
- # a bundled SHA1 routine coming from Mozilla. It is GPL'd and should be fast
- # on non-x86 architectures (e.g. PowerPC), while the OpenSSL version (default
- # choice) has very fast version optimized for i586.
- #
# Define NO_OPENSSL environment variable if you do not have OpenSSL.
# This also implies MOZILLA_SHA1.
#
# Define ARM_SHA1 environment variable when running make to make use of
# a bundled SHA1 routine optimized for ARM.

+ # Define MOZILLA_SHA1 environment variable when running make to make use of

+ # on non-x86 architectures (e.g. PowerPC), while the OpenSSL version (default
+ # choice) has very fast version optimized for i586.
+ #
# Define NEEDS_SSL_WITH_CRYPTO if you need -lcrypto with -lssl (Darwin).
#
# Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
#
# Define NO_MMAP if you want to avoid mmap.
#
- # Define WITH_OWN_SUBPROCESS_PY if you want to use with python 2.3.
+ # Define NO_PREAD if you have a problem with pread() system call (e.g.
+ # cygwin.dll before v1.5.22).
+ #
+ # Define NO_FAST_WORKING_DIRECTORY if accessing objects in pack files is
+ # generally faster on your platform than accessing the working directory.
+ #
+ # Define NO_TRUSTABLE_FILEMODE if your filesystem may claim to support
+ # the executable mode bit, but doesn't really do so.
#
# Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
#
#
# Define NO_ICONV if your libc does not properly support iconv.
#
- # Define NO_ACCURATE_DIFF if your diff program at least sometimes misses
- # a missing newline at the end of the file.
- #
- # Define NO_PYTHON if you want to lose all benefits of the recursive merge.
+ # Define NO_R_TO_GCC if your gcc does not like "-R/path/lib" that
+ # tells runtime paths to dynamic libraries; "-Wl,-rpath=/path/lib"
+ # is used instead.
#
- # Define COLLISION_CHECK below if you believe that SHA1's
- # 1461501637330902918203684832716283019655932542976 hashes do not give you
- # sufficient guarantee that no collisions between objects will ever happen.
-
# Define USE_NSEC below if you want git to care about sub-second file mtimes
# and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
# it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
# randomly break unless your underlying filesystem supports those sub-second
# times (my ext3 doesn't).
-
+ #
# Define USE_STDEV below if you want git to care about the underlying device
# change being considered an inode change from the update-cache perspective.
+ #
+ # Define NO_PERL_MAKEMAKER if you cannot use Makefiles generated by perl's
+ # MakeMaker (e.g. using ActiveState under Cygwin).
