# The default target of this Makefile is...
all::
# Import tree-wide shared Makefile behavior and libraries
include shared.mak
# == Makefile defines ==
#
# These defines change the behavior of the Makefile itself, but have
# no impact on what it builds:
#
# Define V=1 to have a more verbose compile.
#
# == Portability and optional library defines ==
#
# These defines indicate what Git can expect from the OS, what
# libraries are available etc. Much of this is auto-detected in
# config.mak.uname, or in configure.ac when using the optional "make
# configure && ./configure" (see INSTALL).
#
# Define SHELL_PATH to a POSIX shell if your /bin/sh is broken.
#
# Define SANE_TOOL_PATH to a colon-separated list of paths to prepend
# to PATH if your tools in /usr/bin are broken.
#
# Define SOCKLEN_T to a suitable type (such as 'size_t') if your
# system headers do not define a socklen_t type.
#
# Define INLINE to a suitable substitute (such as '__inline' or '') if git
# fails to compile with errors about undefined inline functions or similar.
#
# Define SNPRINTF_RETURNS_BOGUS if you are on a system which snprintf()
# or vsnprintf() return -1 instead of number of characters which would
# have been written to the final string if enough space had been available.
#
# Define FREAD_READS_DIRECTORIES if you are on a system which succeeds
# when attempting to read from an fopen'ed directory (or even to fopen
# it at all).
#
# Define OPEN_RETURNS_EINTR if your open() system call may return EINTR
# when a signal is received (as opposed to restarting).
#
# Define NO_OPENSSL environment variable if you do not have OpenSSL.
#
# Define HAVE_ALLOCA_H if you have working alloca(3) defined in that header.
#
# Define HAVE_PATHS_H if you have paths.h and want to use the default PATH
# it specifies.
#
# Define NO_D_TYPE_IN_DIRENT if your platform defines DT_UNKNOWN but lacks
# d_type in struct dirent (Cygwin 1.5, fixed in Cygwin 1.7).
#
# Define HAVE_STRINGS_H if you have strings.h and need it for strcasecmp.
#
# Define NO_STRCASESTR if you don't have strcasestr.
#
# Define NO_MEMMEM if you don't have memmem.
#
# Define NO_GETPAGESIZE if you don't have getpagesize.
#
# Define NO_STRLCPY if you don't have strlcpy.
#
# Define NO_STRTOUMAX if you don't have both strtoimax and strtoumax in the
# C library. If your compiler also does not support long long or does not have
# strtoull, define NO_STRTOULL.
#
# Define NO_SETENV if you don't have setenv in the C library.
#
# Define NO_UNSETENV if you don't have unsetenv in the C library.
#
# Define NO_MKDTEMP if you don't have mkdtemp in the C library.
#
# Define MKDIR_WO_TRAILING_SLASH if your mkdir() can't deal with trailing slash.
#
# Define NO_GECOS_IN_PWENT if you don't have pw_gecos in struct passwd
# in the C library.
#
# Define NO_LIBGEN_H if you don't have libgen.h.
#
# Define NEEDS_LIBGEN if your libgen needs -lgen when linking
#
# Define NO_SYS_SELECT_H if you don't have sys/select.h.
#
# Define NO_SYMLINK_HEAD if you never want .git/HEAD to be a symbolic link.
# Enable it on Windows. By default, symrefs are still used.
#
# Define NO_SVN_TESTS if you want to skip time-consuming SVN interoperability
# tests. These tests take up a significant amount of the total test time
# but are not needed unless you plan to talk to SVN repos.
#
# Define NO_FINK if you are building on Darwin/Mac OS X, have Fink
# installed in /sw, but don't want GIT to link against any libraries
# installed there. If defined you may specify your own (or Fink's)
# include directories and library directories by defining CFLAGS
# and LDFLAGS appropriately.
#
# Define NO_DARWIN_PORTS if you are building on Darwin/Mac OS X,
# have DarwinPorts (which is an old name for MacPorts) installed
# in /opt/local, but don't want GIT to
# link against any libraries installed there. If defined you may
# specify your own (or DarwinPort's) include directories and
# library directories by defining CFLAGS and LDFLAGS appropriately.
#
# Define NO_HOMEBREW if you don't want to use gettext, libiconv and
# msgfmt installed by Homebrew.
#
# Define HOMEBREW_PREFIX if you have Homebrew installed in a non-default
# location on macOS or on Linux and want to use it.
#
# Define USE_HOMEBREW_LIBICONV to link against libiconv installed by
# Homebrew, if present.
#
# Define NO_APPLE_COMMON_CRYPTO if you are building on Darwin/Mac OS X
# and do not want to use Apple's CommonCrypto library. This allows you
# to provide your own OpenSSL library, for example from MacPorts.
#
# Define NEEDS_CRYPTO_WITH_SSL if you need -lcrypto when using -lssl (Darwin).
#
# Define NEEDS_SSL_WITH_CRYPTO if you need -lssl when using -lcrypto (Darwin).
#
# Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
#
# Define NEEDS_LIBINTL_BEFORE_LIBICONV if you need libintl before libiconv.
#
# Define NO_INTPTR_T if you don't have intptr_t or uintptr_t.
#
# Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
# Patrick Mauritz).
#
# Define NEEDS_RESOLV if linking with -lnsl and/or -lsocket is not enough.
# Notably on Solaris hstrerror resides in libresolv and on Solaris 7
# inet_ntop and inet_pton additionally reside there.
#
# Define NO_MMAP if you want to avoid mmap.
#
# Define MMAP_PREVENTS_DELETE if a file that is currently mmapped cannot be
# deleted or cannot be replaced using rename().
#
# Define NO_POLL_H if you don't have poll.h.
#
# Define NO_SYS_POLL_H if you don't have sys/poll.h.
#
# Define NO_POLL if you do not have or don't want to use poll().
# This also implies NO_POLL_H and NO_SYS_POLL_H.
#
# Define NEEDS_SYS_PARAM_H if you need to include sys/param.h to compile,
# *PLEASE* REPORT to git@vger.kernel.org if your platform needs this;
# we want to know more about the issue.
#
# Define NO_PTHREADS if you do not have or do not want to use Pthreads.
#
# Define NO_PREAD if you have a problem with pread() system call (e.g.
# cygwin1.dll before v1.5.22).
#
# Define NO_SETITIMER if you don't have setitimer()
#
# Define NO_STRUCT_ITIMERVAL if you don't have struct itimerval
# This also implies NO_SETITIMER
#
# 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 CSPRNG_METHOD to "arc4random" if your system has arc4random and
# arc4random_buf, "libbsd" if your system has those functions from libbsd,
# "getrandom" if your system has getrandom, "getentropy" if your system has
# getentropy, "rtlgenrandom" for RtlGenRandom (Windows only), or "openssl" if
# you'd want to use the OpenSSL CSPRNG. You may set multiple options with
# spaces, in which case a suitable option will be chosen. If unset or set to
# anything else, defaults to using "/dev/urandom".
#
# Define NEEDS_MODE_TRANSLATION if your OS strays from the typical file type
# bits in mode values (e.g. z/OS defines I_SFMT to 0xFF000000 as opposed to the
# usual 0xF000).
#
# Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
#
# Define NO_UNIX_SOCKETS if your system does not offer unix sockets.
#
# Define NO_SOCKADDR_STORAGE if your platform does not have struct
# sockaddr_storage.
#
# Define NO_ICONV if your libc does not properly support iconv.
#
# Define OLD_ICONV if your library has an old iconv(), where the second
# (input buffer pointer) parameter is declared with type (const char **).
#
# Define ICONV_OMITS_BOM if your iconv implementation does not write a
# byte-order mark (BOM) when writing UTF-16 or UTF-32 and always writes in
# big-endian format.
#
# Define NO_DEFLATE_BOUND if your zlib does not have deflateBound. Define
# ZLIB_NG if you want to use zlib-ng instead of zlib.
#
# Define NO_NORETURN if using buggy versions of gcc 4.6+ and profile feedback,
# as the compiler can crash (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=49299)
#
# 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. On
# Linux, kernel 2.6.11 or newer is required for reliable sub-second file times
# on file systems with exactly 1 ns or 1 s resolution. If you intend to use Git
# on other file systems (e.g. CEPH, CIFS, NTFS, UDF), don't enable USE_NSEC. See
# Documentation/technical/racy-git.adoc for details.
#
# Define USE_ST_TIMESPEC if your "struct stat" uses "st_ctimespec" instead of
# "st_ctim"
#
# Define NO_NSEC if your "struct stat" does not have "st_ctim.tv_nsec"
# available. This automatically turns USE_NSEC off.
#
# Define USE_STDEV below if you want git to care about the underlying device
# change being considered an inode change from the update-index perspective.
#
# Define NO_ST_BLOCKS_IN_STRUCT_STAT if your platform does not have st_blocks
# field that counts the on-disk footprint in 512-byte blocks.
#
# Define USE_ASCIIDOCTOR to use Asciidoctor instead of AsciiDoc to build the
# documentation.
#
# Define ASCIIDOCTOR_EXTENSIONS_LAB to point to the location of the Asciidoctor
# Extensions Lab if you have it available.
#
# Define PERL_PATH to the path of your Perl binary (usually /usr/bin/perl).
#
# Define NO_PERL if you do not want Perl scripts or libraries at all.
#
# Define NO_PERL_CPAN_FALLBACKS if you do not want to install bundled
# copies of CPAN modules that serve as a fallback in case the modules
# are not available on the system. This option is intended for
# distributions that want to use their packaged versions of Perl
# modules, instead of the fallbacks shipped with Git.
#
# Define NO_GITWEB if you do not want to build or install
# 'gitweb'. Note that defining NO_PERL currently has the same effect
# on not installing gitweb, but not on whether it's built in the
# gitweb/ directory.
#
# Define PYTHON_PATH to the path of your Python binary (often /usr/bin/python
# but /usr/bin/python2.7 or /usr/bin/python3 on some platforms).
#
# Define NO_PYTHON if you do not want Python scripts or libraries at all.
#
# Define NO_TCLTK if you do not want Tcl/Tk GUI.
#
# The TCL_PATH variable governs the location of the Tcl interpreter
# used to optimize git-gui for your system. Only used if NO_TCLTK
# is not set. Defaults to the bare 'tclsh'.
#
# The TCLTK_PATH variable governs the location of the Tcl/Tk interpreter.
# If not set it defaults to the bare 'wish'. If it is set to the empty
# string then NO_TCLTK will be forced (this is used by configure script).
#
# Define INTERNAL_QSORT to use Git's implementation of qsort(), which
# is a simplified version of the merge sort used in glibc. This is
# recommended if Git triggers O(n^2) behavior in your platform's qsort().
#
# Define HAVE_ISO_QSORT_S if your platform provides a qsort_s() that's
# compatible with the one described in C11 Annex K.
#
# Define UNRELIABLE_FSTAT if your system's fstat does not return the same
# information on a not yet closed file that lstat would return for the same
# file after it was closed.
#
# Define OBJECT_CREATION_USES_RENAMES if your operating systems has problems
# when hardlinking a file to another name and unlinking the original file right
# away (some NTFS drivers seem to zero the contents in that scenario).
#
# Define INSTALL_SYMLINKS if you prefer to have everything that can be
# symlinked between bin/ and libexec/ to use relative symlinks between
# the two. This option overrides NO_CROSS_DIRECTORY_HARDLINKS and
# NO_INSTALL_HARDLINKS which will also use symlinking by indirection
# within the same directory in some cases, INSTALL_SYMLINKS will
# always symlink to the final target directly.
#
# Define NO_CROSS_DIRECTORY_HARDLINKS if you plan to distribute the installed
# programs as a tar, where bin/ and libexec/ might be on different file systems.
#
# Define NO_INSTALL_HARDLINKS if you prefer to use either symbolic links or
# copies to install built-in git commands e.g. git-cat-file.
#
# Define SKIP_DASHED_BUILT_INS if you do not need the dashed versions of the
# built-ins to be linked/copied at all.
#
# Define OVERRIDE_STRDUP to override the libc version of strdup(3).
# This is necessary when using a custom allocator in order to avoid
# crashes due to allocation and free working on different 'heaps'.
#
# Define NO_REGEX if your C library lacks regex support with REG_STARTEND
# feature.
#
# Define USE_ENHANCED_BASIC_REGULAR_EXPRESSIONS if your C library provides
# the flag REG_ENHANCED and you'd like to use it to enable enhanced basic
# regular expressions.
#
# Define HAVE_DEV_TTY if your system can open /dev/tty to interact with the
# user.
#
# Define JSMIN to point to JavaScript minifier that functions as
# a filter to have gitweb.js minified.
#
# Define CSSMIN to point to a CSS minifier in order to generate a minified
# version of gitweb.css
#
# Define DEFAULT_PAGER to a sensible pager command (defaults to "less") if
# you want to use something different. The value will be interpreted by the
# shell at runtime when it is used.
#
# Define DEFAULT_EDITOR to a sensible editor command (defaults to "vi") if you
# want to use something different. The value will be interpreted by the shell
# if necessary when it is used. Examples:
#
# DEFAULT_EDITOR='~/bin/vi',
# DEFAULT_EDITOR='$GIT_FALLBACK_EDITOR',
# DEFAULT_EDITOR='"C:\Program Files\Vim\gvim.exe" --nofork'
#
# Define COMPUTE_HEADER_DEPENDENCIES to "yes" if you want dependencies on
# header files to be automatically computed, to avoid rebuilding objects when
# an unrelated header file changes. Define it to "no" to use the hard-coded
# dependency rules. The default is "auto", which means to use computed header
# dependencies if your compiler is detected to support it.
#
# Define NATIVE_CRLF if your platform uses CRLF for line endings.
#
# Define GIT_USER_AGENT if you want to change how git identifies itself during
# network interactions. The default is "git/$(GIT_VERSION)".
#
# Define DEFAULT_HELP_FORMAT to "man", "info" or "html"
# (defaults to "man") if you want to have a different default when
# "git help" is called without a parameter specifying the format.
#
# Define GIT_TEST_INDEX_VERSION to 2, 3 or 4 to run the test suite
# with a different indexfile format version. If it isn't set the index
# file format used is index-v[23].
#
# Define GIT_TEST_UTF8_LOCALE to preferred utf-8 locale for testing.
# If it isn't set, fallback to $LC_ALL, $LANG or use the first utf-8
# locale returned by "locale -a".
#
# Define TEST_CONTRIB_TOO to make "make test" run tests in contrib/
# directories.
#
# Define HAVE_CLOCK_GETTIME if your platform has clock_gettime.
#
# Define HAVE_CLOCK_MONOTONIC if your platform has CLOCK_MONOTONIC.
#
# Define HAVE_SYNC_FILE_RANGE if your platform has sync_file_range.
#
# Define HAVE_BSD_SYSCTL if your platform has a BSD-compatible sysctl function.
#
# Define HAVE_GETDELIM if your system has the getdelim() function.
#
# Define FILENO_IS_A_MACRO if fileno() is a macro, not a real function.
#
# Define NEED_ACCESS_ROOT_HANDLER if access() under root may success for X_OK
# even if execution permission isn't granted for any user.
#
# Define PAGER_ENV to a SP separated VAR=VAL pairs to define
# default environment variables to be passed when a pager is spawned, e.g.
#
# PAGER_ENV = LESS=FRX LV=-c
#
# to say "export LESS=FRX (and LV=-c) if the environment variable
# LESS (and LV) is not set, respectively".
#
# Define TEST_SHELL_PATH if you want to use a shell besides SHELL_PATH for
# running the test scripts (e.g., bash has better support for "set -x"
# tracing).
#
# When cross-compiling, define HOST_CPU as the canonical name of the CPU on
# which the built Git will run (for instance "x86_64").
#
# Define RUNTIME_PREFIX to configure Git to resolve its ancillary tooling and
# support files relative to the location of the runtime binary, rather than
# hard-coding them into the binary. Git installations built with RUNTIME_PREFIX
# can be moved to arbitrary filesystem locations. RUNTIME_PREFIX also causes
# Perl scripts to use a modified entry point header allowing them to resolve
# support files at runtime.
#
# When using RUNTIME_PREFIX, define HAVE_BSD_KERN_PROC_SYSCTL if your platform
# supports the KERN_PROC BSD sysctl function.
#
# When using RUNTIME_PREFIX, define PROCFS_EXECUTABLE_PATH if your platform
# mounts a "procfs" filesystem capable of resolving the path of the current
# executable. If defined, this must be the canonical path for the "procfs"
# current executable path.
#
# When using RUNTIME_PREFIX, define HAVE_NS_GET_EXECUTABLE_PATH if your platform
# supports calling _NSGetExecutablePath to retrieve the path of the running
# executable.
#
# When using RUNTIME_PREFIX, define HAVE_ZOS_GET_EXECUTABLE_PATH if your platform
# supports calling __getprogramdir and getprogname to retrieve the path of the
# running executable.
#
# When using RUNTIME_PREFIX, define HAVE_WPGMPTR if your platform offers
# the global variable _wpgmptr containing the absolute path of the current
# executable (this is the case on Windows).
#
# INSTALL_STRIP can be set to "-s" to strip binaries during installation,
# if your $(INSTALL) command supports the option.
#
# Define GENERATE_COMPILATION_DATABASE to "yes" to generate JSON compilation
# database entries during compilation if your compiler supports it, using the
# `-MJ` flag. The JSON entries will be placed in the `compile_commands/`
# directory, and the JSON compilation database 'compile_commands.json' will be
# created at the root of the repository.
#
# If your platform supports a built-in fsmonitor backend, set
# FSMONITOR_DAEMON_BACKEND to the "<name>" of the corresponding
# `compat/fsmonitor/fsm-listen-<name>.c` and
# `compat/fsmonitor/fsm-health-<name>.c` files
# that implement the `fsm_listen__*()` and `fsm_health__*()` routines.
#
# If your platform has OS-specific ways to tell if a repo is incompatible with
# fsmonitor (whether the hook or IPC daemon version), set FSMONITOR_OS_SETTINGS
# to the "<name>" of the corresponding `compat/fsmonitor/fsm-settings-<name>.c`
# and `compat/fsmonitor/fsm-ipc-<name>.c` files.
#
# Define LINK_FUZZ_PROGRAMS if you want `make all` to also build the fuzz test
# programs in oss-fuzz/.
#
# Define INCLUDE_LIBGIT_RS if you want `make all` and `make test` to build and
# test the Rust crates in contrib/libgit-sys and contrib/libgit-rs.
#
# === Optional library: libintl ===
#
# Define NO_GETTEXT if you don't want Git output to be translated.
# A translated Git requires GNU libintl or another gettext implementation,
# plus libintl-perl at runtime.
#
# Define USE_GETTEXT_SCHEME and set it to 'fallthrough', if you don't trust
# the installed gettext translation of the shell scripts output.
#
# Define HAVE_LIBCHARSET_H if you haven't set NO_GETTEXT and you can't
# trust the langinfo.h's nl_langinfo(CODESET) function to return the
# current character set. GNU and Solaris have a nl_langinfo(CODESET),
# FreeBSD can use either, but MinGW and some others need to use
# libcharset.h's locale_charset() instead.
#
# Define CHARSET_LIB to the library you need to link with in order to
# use locale_charset() function. On some platforms this needs to set to
# -lcharset, on others to -liconv .
#
# Define LIBC_CONTAINS_LIBINTL if your gettext implementation doesn't
# need -lintl when linking.
#
# Define NO_MSGFMT_EXTENDED_OPTIONS if your implementation of msgfmt
# doesn't support GNU extensions like --check and --statistics
#
# === Optional library: libexpat ===
#
# Define NO_EXPAT if you do not have expat installed. git-http-push is
# not built, and you cannot push using http:// and https:// transports (dumb).
#
# Define EXPATDIR=/foo/bar if your expat header and library files are in
# /foo/bar/include and /foo/bar/lib directories.
#
# Define EXPAT_NEEDS_XMLPARSE_H if you have an old version of expat (e.g.,
# 1.1 or 1.2) that provides xmlparse.h instead of expat.h.
# === Optional library: libcurl ===
#
# Define NO_CURL if you do not have libcurl installed. git-http-fetch and
# git-http-push are not built, and you cannot use http:// and https://
# transports (neither smart nor dumb).
#
# Define CURLDIR=/foo/bar if your curl header and library files are in
# /foo/bar/include and /foo/bar/lib directories.
#
# Define CURL_CONFIG to curl's configuration program that prints information
# about the library (e.g., its version number). The default is 'curl-config'.
#
# Define CURL_LDFLAGS to specify flags that you need to link when using libcurl,
# if you do not want to rely on the libraries provided by CURL_CONFIG. The
# default value is a result of `curl-config --libs`. An example value for
# CURL_LDFLAGS is as follows:
#
# CURL_LDFLAGS=-lcurl
#
# Define LAZYLOAD_LIBCURL to dynamically load the libcurl; This can be useful
# if Multiple libcurl versions exist (with different file names) that link to
# various SSL/TLS backends, to support the `http.sslBackend` runtime switch in
# such a scenario.
#
# === Optional library: libpcre2 ===
#
# Define USE_LIBPCRE if you have and want to use libpcre. Various
# commands such as log and grep offer runtime options to use
# Perl-compatible regular expressions instead of standard or extended
# POSIX regular expressions.
#
# Only libpcre version 2 is supported. USE_LIBPCRE2 is a synonym for
# USE_LIBPCRE, support for the old USE_LIBPCRE1 has been removed.
#
# Define LIBPCREDIR=/foo/bar if your PCRE header and library files are
# in /foo/bar/include and /foo/bar/lib directories.
#
# == Optional Rust support ==
#
# Define NO_RUST if you want to disable features and subsystems written in Rust
# from being compiled into Git. For now, Rust is still an optional feature of
# the build process. With Git 3.0 though, Rust will always be enabled.
#
# Building Rust code requires Cargo.
#
# == SHA-1 and SHA-256 defines ==
#
# === SHA-1 backend ===
#
# ==== Security ====
#
# Due to the SHAttered (https://shattered.io) attack vector on SHA-1
# it's strongly recommended to use the sha1collisiondetection
# counter-cryptanalysis library for SHA-1 hashing.
#
# If you know that you can trust the repository contents, or where
# potential SHA-1 attacks are otherwise mitigated the other backends
# listed in "SHA-1 implementations" are faster than
# sha1collisiondetection.
#
# ==== Default SHA-1 backend ====
#
# If no *_SHA1 backend is picked, the first supported one listed in
# "SHA-1 implementations" will be picked.
#
# ==== Options common to all SHA-1 implementations ====
#
# Define SHA1_MAX_BLOCK_SIZE to limit the amount of data that will be hashed
# in one call to the platform's SHA1_Update(). e.g. APPLE_COMMON_CRYPTO
# wants 'SHA1_MAX_BLOCK_SIZE=1024L*1024L*1024L' defined.
#
# ==== SHA-1 implementations ====
#
# Define OPENSSL_SHA1 to link to the SHA-1 routines from the OpenSSL
# library.
#
# Define BLK_SHA1 to make use of optimized C SHA-1 routines bundled
# with git (in the block-sha1/ directory).
#
# Define APPLE_COMMON_CRYPTO_SHA1 to use Apple's CommonCrypto for
# SHA-1.
#
# Define the same Makefile knobs as above, but suffixed with _UNSAFE to
# use the corresponding implementations for unsafe SHA-1 hashing for
# non-cryptographic purposes.
#
# If don't enable any of the *_SHA1 settings in this section, Git will
# default to its built-in sha1collisiondetection library, which is a
# collision-detecting sha1 This is slower, but may detect attempted
# collision attacks.
#
# ==== Options for the sha1collisiondetection library ====
#
# Define DC_SHA1_EXTERNAL if you want to build / link
# git with the external SHA1 collision-detect library.
# Without this option, i.e. the default behavior is to build git with its
# own built-in code (or submodule).
#
# Define DC_SHA1_SUBMODULE to use the
# sha1collisiondetection shipped as a submodule instead of the
# non-submodule copy in sha1dc/. This is an experimental option used
# by the git project to migrate to using sha1collisiondetection as a
# submodule.
#
# === SHA-256 backend ===
#
# ==== Security ====
#
# Unlike SHA-1 the SHA-256 algorithm does not suffer from any known
# vulnerabilities, so any implementation will do.
#
# ==== SHA-256 implementations ====
#
# Define OPENSSL_SHA256 to use the SHA-256 routines in OpenSSL.
#
# Define NETTLE_SHA256 to use the SHA-256 routines in libnettle.
#
# Define GCRYPT_SHA256 to use the SHA-256 routines in libgcrypt.
#
# If don't enable any of the *_SHA256 settings in this section, Git
# will default to its built-in sha256 implementation.
#
# == DEVELOPER defines ==
#
# Define DEVELOPER to enable more compiler warnings. Compiler version
# and family are auto detected, but could be overridden by defining
# COMPILER_FEATURES (see config.mak.dev). You can still set
# CFLAGS="..." in combination with DEVELOPER enables, whether that's
# for tweaking something unrelated (e.g. optimization level), or for
# selectively overriding something DEVELOPER or one of the DEVOPTS
# (see just below) brings in.
#
# When DEVELOPER is set, DEVOPTS can be used to control compiler
# options. This variable contains keywords separated by
# whitespace. The following keywords are recognized:
#
# no-error:
#
# suppresses the -Werror that implicitly comes with
# DEVELOPER=1. Useful for getting the full set of errors
# without immediately dying, or for logging them.
#
# extra-all:
#
# The DEVELOPER mode enables -Wextra with a few exceptions. By
# setting this flag the exceptions are removed, and all of
# -Wextra is used.
#
# no-pedantic:
#
# Disable -pedantic compilation.
# Set our default configuration.
#
# Among the variables below, these:
# gitexecdir
# template_dir
# sysconfdir
# can be specified as a relative path some/where/else;
# this is interpreted as relative to $(prefix) and "git" built with
# RUNTIME_PREFIX flag will figure out (at runtime) where they are
# based on the path to the executable.
# Additionally, the following will be treated as relative by "git" if they
# begin with "$(prefix)/":
# mandir
# infodir
# htmldir
# localedir
# perllibdir
# This can help installing the suite in a relocatable way.
