# 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_STRTOUMAX if you don't have both strtoimax and strtoumax in the

#

# 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 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_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).

# 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 [email protected] 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 USE_NED_ALLOCATOR if you want to replace the platforms default

# memory allocators with the nedmalloc allocator written by Niall Douglas.

#

# 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'.

# It's defined automatically if USE_NED_ALLOCATOR is set.

#

# 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 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`

# that implements the `fsm_os_settings__*()` routines.

#

# 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

#

# === 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.

#

# == 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.
