#
9
# These defines change the behavior of the Makefile itself, but have
10

11
#
12
# Define V=1 to have a more verbose compile.
13
#
14
# == Portability and optional library defines ==
15
#
16
# These defines indicate what Git can expect from the OS, what
17
# libraries are available etc. Much of this is auto-detected in
18
# config.mak.uname, or in configure.ac when using the optional "make

30
# fails to compile with errors about undefined inline functions or similar.
31
#
32
# Define SNPRINTF_RETURNS_BOGUS if you are on a system which snprintf()
33
# or vsnprintf() return -1 instead of number of characters which would
34
# have been written to the final string if enough space had been available.
35
#
36
# Define FREAD_READS_DIRECTORIES if you are on a system which succeeds
37
# when attempting to read from an fopen'ed directory (or even to fopen
38
# it at all).

90
#
91
# Define NO_FINK if you are building on Darwin/Mac OS X, have Fink
92
# installed in /sw, but don't want GIT to link against any libraries

152
# Define NO_FAST_WORKING_DIRECTORY if accessing objects in pack files is

161
# getentropy, "rtlgenrandom" for RtlGenRandom (Windows only), or "openssl" if
162
# you'd want to use the OpenSSL CSPRNG.  You may set multiple options with
163
# spaces, in which case a suitable option will be chosen.  If unset or set to
164
# anything else, defaults to using "/dev/urandom".
165
#
166
# Define NEEDS_MODE_TRANSLATION if your OS strays from the typical file type
167
# bits in mode values (e.g. z/OS defines I_SFMT to 0xFF000000 as opposed to the

187
#
188

190
#
191
# Define USE_NSEC below if you want git to care about sub-second file mtimes
192
# and ctimes. Note that you need recent glibc (at least 2.2.4) for this. On
193
# Linux, kernel 2.6.11 or newer is required for reliable sub-second file times
194
# on file systems with exactly 1 ns or 1 s resolution. If you intend to use Git
195
# on other file systems (e.g. CEPH, CIFS, NTFS, UDF), don't enable USE_NSEC. See
196
# Documentation/technical/racy-git.txt for details.
197
#
198

# "st_ctim"
200
#
201
# Define NO_NSEC if your "struct stat" does not have "st_ctim.tv_nsec"
202
# available.  This automatically turns USE_NSEC off.

205
# change being considered an inode change from the update-index perspective.
206

208
# field that counts the on-disk footprint in 512-byte blocks.

# Define USE_ASCIIDOCTOR to use Asciidoctor instead of AsciiDoc to build the
211
# documentation.
212
#
213
# Define ASCIIDOCTOR_EXTENSIONS_LAB to point to the location of the Asciidoctor
214
# Extensions Lab if you have it available.
215
#
216
# Define PERL_PATH to the path of your Perl binary (usually /usr/bin/perl).
217
#
218
# Define NO_PERL if you do not want Perl scripts or libraries at all.
219

# Define NO_PERL_CPAN_FALLBACKS if you do not want to install bundled
221
# copies of CPAN modules that serve as a fallback in case the modules
222
# are not available on the system. This option is intended for
223
# distributions that want to use their packaged versions of Perl
224
# modules, instead of the fallbacks shipped with Git.
225
#
226
# Define NO_GITWEB if you do not want to build or install
227
# 'gitweb'. Note that defining NO_PERL currently has the same effect
228
# on not installing gitweb, but not on whether it's built in the
229
# gitweb/ directory.
230
#
231
# Define PYTHON_PATH to the path of your Python binary (often /usr/bin/python
232

233
#
234
# Define NO_PYTHON if you do not want Python scripts or libraries at all.
235
#
236
# Define NO_TCLTK if you do not want Tcl/Tk GUI.
237
#
238
# The TCL_PATH variable governs the location of the Tcl interpreter
239
# used to optimize git-gui for your system.  Only used if NO_TCLTK
240
# is not set.  Defaults to the bare 'tclsh'.
241
#
242
# The TCLTK_PATH variable governs the location of the Tcl/Tk interpreter.
243
# If not set it defaults to the bare 'wish'. If it is set to the empty
244
# string then NO_TCLTK will be forced (this is used by configure script).
245
#
246
# Define INTERNAL_QSORT to use Git's implementation of qsort(), which
247
# 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().
249
#
250

256
#
257
# Define OBJECT_CREATION_USES_RENAMES if your operating systems has problems
258
# when hardlinking a file to another name and unlinking the original file right
259
# away (some NTFS drivers seem to zero the contents in that scenario).
260
#
261
# Define INSTALL_SYMLINKS if you prefer to have everything that can be
262
# symlinked between bin/ and libexec/ to use relative symlinks between
263
# the two. This option overrides NO_CROSS_DIRECTORY_HARDLINKS and
264
# NO_INSTALL_HARDLINKS which will also use symlinking by indirection
265
# within the same directory in some cases, INSTALL_SYMLINKS will
266
# always symlink to the final target directly.
267
#
268
# Define NO_CROSS_DIRECTORY_HARDLINKS if you plan to distribute the installed
269
# programs as a tar, where bin/ and libexec/ might be on different file systems.
270
#
271
# Define NO_INSTALL_HARDLINKS if you prefer to use either symbolic links or
272
# copies to install built-in git commands e.g. git-cat-file.

278
# memory allocators with the nedmalloc allocator written by Niall Douglas.

281
# This is necessary when using a custom allocator in order to avoid

283
# It's defined automatically if USE_NED_ALLOCATOR is set.
284
#
285
# Define NO_REGEX if your C library lacks regex support with REG_STARTEND
286
# feature.
287
#
288
# Define USE_ENHANCED_BASIC_REGULAR_EXPRESSIONS if your C library provides
289
# the flag REG_ENHANCED and you'd like to use it to enable enhanced basic
290
# regular expressions.
291
#
292
# Define HAVE_DEV_TTY if your system can open /dev/tty to interact with the
293
# user.
294
#
295
# Define JSMIN to point to JavaScript minifier that functions as
296
# a filter to have gitweb.js minified.
297

298
# Define CSSMIN to point to a CSS minifier in order to generate a minified
299
# version of gitweb.css
300
#
301

# shell at runtime when it is used.
304
#
305
# Define DEFAULT_EDITOR to a sensible editor command (defaults to "vi") if you
306
# want to use something different.  The value will be interpreted by the shell
307

#
309
#   DEFAULT_EDITOR='~/bin/vi',
310
#   DEFAULT_EDITOR='$GIT_FALLBACK_EDITOR',
311
#   DEFAULT_EDITOR='"C:\Program Files\Vim\gvim.exe" --nofork'
312
#
313
# Define COMPUTE_HEADER_DEPENDENCIES to "yes" if you want dependencies on
314
# header files to be automatically computed, to avoid rebuilding objects when
315
# an unrelated header file changes.  Define it to "no" to use the hard-coded
316
# dependency rules.  The default is "auto", which means to use computed header
317
# dependencies if your compiler is detected to support it.
318
#
319
# Define NATIVE_CRLF if your platform uses CRLF for line endings.
320
#
321
# Define GIT_USER_AGENT if you want to change how git identifies itself during
322
# network interactions.  The default is "git/$(GIT_VERSION)".
323
#
324
# Define DEFAULT_HELP_FORMAT to "man", "info" or "html"
325
# (defaults to "man") if you want to have a different default when
326
# "git help" is called without a parameter specifying the format.
327
#
328
# Define GIT_TEST_INDEX_VERSION to 2, 3 or 4 to run the test suite
329
# with a different indexfile format version.  If it isn't set the index
330
# file format used is index-v[23].
331
#
332
# Define GIT_TEST_UTF8_LOCALE to preferred utf-8 locale for testing.
333

358
#
359
# to say "export LESS=FRX (and LV=-c) if the environment variable
360
# LESS (and LV) is not set, respectively".
361
#
362
# Define TEST_SHELL_PATH if you want to use a shell besides SHELL_PATH for
363
# running the test scripts (e.g., bash has better support for "set -x"
364
# tracing).
365
#
366
# When cross-compiling, define HOST_CPU as the canonical name of the CPU on
367
# which the built Git will run (for instance "x86_64").
368
#
369
# Define RUNTIME_PREFIX to configure Git to resolve its ancillary tooling and
370
# support files relative to the location of the runtime binary, rather than
371
# hard-coding them into the binary. Git installations built with RUNTIME_PREFIX
372
# can be moved to arbitrary filesystem locations. RUNTIME_PREFIX also causes
373
# Perl scripts to use a modified entry point header allowing them to resolve
374
# support files at runtime.
375
#
376
# When using RUNTIME_PREFIX, define HAVE_BSD_KERN_PROC_SYSCTL if your platform
377

# When using RUNTIME_PREFIX, define HAVE_WPGMPTR if your platform offers
389
# the global variable _wpgmptr containing the absolute path of the current
390
# executable (this is the case on Windows).
391
#
392
# INSTALL_STRIP can be set to "-s" to strip binaries during installation,
393
# if your $(INSTALL) command supports the option.
394
#
395
# Define GENERATE_COMPILATION_DATABASE to "yes" to generate JSON compilation
396
# database entries during compilation if your compiler supports it, using the

398
# directory, and the JSON compilation database 'compile_commands.json' will be
399
# created at the root of the repository.
400
#
401
# If your platform supports a built-in fsmonitor backend, set
402
# FSMONITOR_DAEMON_BACKEND to the "<name>" of the corresponding
403
# `compat/fsmonitor/fsm-listen-<name>.c` and

# `compat/fsmonitor/fsm-health-<name>.c` files
405
# that implement the `fsm_listen__*()` and `fsm_health__*()` routines.
406
#
407
# If your platform has OS-specific ways to tell if a repo is incompatible with
408
# fsmonitor (whether the hook or IPC daemon version), set FSMONITOR_OS_SETTINGS
409
# to the "<name>" of the corresponding `compat/fsmonitor/fsm-settings-<name>.c`
410
# that implements the `fsm_os_settings__*()` routines.
411
#
412
# Define LINK_FUZZ_PROGRAMS if you want `make all` to also build the fuzz test
413
# programs in oss-fuzz/.
414
#
415
# === Optional library: libintl ===
416
#
417
# Define NO_GETTEXT if you don't want Git output to be translated.
418
# A translated Git requires GNU libintl or another gettext implementation,
419
# plus libintl-perl at runtime.
420
#
421
# Define USE_GETTEXT_SCHEME and set it to 'fallthrough', if you don't trust
422
# the installed gettext translation of the shell scripts output.
423
#
424
# Define HAVE_LIBCHARSET_H if you haven't set NO_GETTEXT and you can't
425
# trust the langinfo.h's nl_langinfo(CODESET) function to return the

# current character set. GNU and Solaris have a nl_langinfo(CODESET),
427
# FreeBSD can use either, but MinGW and some others need to use
428
# libcharset.h's locale_charset() instead.
429
#
430
# Define CHARSET_LIB to the library you need to link with in order to
431
# use locale_charset() function.  On some platforms this needs to set to
432
# -lcharset, on others to -liconv .
433
#
434
# Define LIBC_CONTAINS_LIBINTL if your gettext implementation doesn't
435
# need -lintl when linking.
436
#
437
# Define NO_MSGFMT_EXTENDED_OPTIONS if your implementation of msgfmt
438
# doesn't support GNU extensions like --check and --statistics
439
#
440
# === Optional library: libexpat ===
441
#
442
# Define NO_EXPAT if you do not have expat installed.  git-http-push is
443
# not built, and you cannot push using http:// and https:// transports (dumb).
444
#
445
# Define EXPATDIR=/foo/bar if your expat header and library files are in
446
# /foo/bar/include and /foo/bar/lib directories.
447
#
448
# Define EXPAT_NEEDS_XMLPARSE_H if you have an old version of expat (e.g.,
449
# 1.1 or 1.2) that provides xmlparse.h instead of expat.h.
450

451
# === Optional library: libcurl ===
452
#
453
# Define NO_CURL if you do not have libcurl installed.  git-http-fetch and
454
# git-http-push are not built, and you cannot use http:// and https://
455
# transports (neither smart nor dumb).
456
#
457
# Define CURLDIR=/foo/bar if your curl header and library files are in
458
# /foo/bar/include and /foo/bar/lib directories.
459
#
460
# Define CURL_CONFIG to curl's configuration program that prints information
461
# about the library (e.g., its version number).  The default is 'curl-config'.
462
#
463
# Define CURL_LDFLAGS to specify flags that you need to link when using libcurl,
464
# if you do not want to rely on the libraries provided by CURL_CONFIG.  The
465
# default value is a result of `curl-config --libs`.  An example value for
466
# CURL_LDFLAGS is as follows:
467
#
468
#     CURL_LDFLAGS=-lcurl
469
#
470
# === Optional library: libpcre2 ===
471
#
472
# Define USE_LIBPCRE if you have and want to use libpcre. Various
473
# commands such as log and grep offer runtime options to use
474
# Perl-compatible regular expressions instead of standard or extended
475
# POSIX regular expressions.
476
#
477
# Only libpcre version 2 is supported. USE_LIBPCRE2 is a synonym for
478
# USE_LIBPCRE, support for the old USE_LIBPCRE1 has been removed.
479
#
480
# Define LIBPCREDIR=/foo/bar if your PCRE header and library files are
481
# in /foo/bar/include and /foo/bar/lib directories.
482
#
483
# == SHA-1 and SHA-256 defines ==
484
#
485
# === SHA-1 backend ===
486
#
487
# ==== Security ====
488
#
489
# Due to the SHAttered (https://shattered.io) attack vector on SHA-1
490
# it's strongly recommended to use the sha1collisiondetection
491
# counter-cryptanalysis library for SHA-1 hashing.
492
#
493
# If you know that you can trust the repository contents, or where
494
# potential SHA-1 attacks are otherwise mitigated the other backends
495
# listed in "SHA-1 implementations" are faster than
496
# sha1collisiondetection.
497
#
498
# ==== Default SHA-1 backend ====
499
#
500
# If no *_SHA1 backend is picked, the first supported one listed in
501
# "SHA-1 implementations" will be picked.
502
#
503
# ==== Options common to all SHA-1 implementations ====
504
#
505
# Define SHA1_MAX_BLOCK_SIZE to limit the amount of data that will be hashed
506
# in one call to the platform's SHA1_Update(). e.g. APPLE_COMMON_CRYPTO
507
# wants 'SHA1_MAX_BLOCK_SIZE=1024L*1024L*1024L' defined.
508
#
509
# ==== SHA-1 implementations ====
510
#
511
# Define OPENSSL_SHA1 to link to the SHA-1 routines from the OpenSSL
512
# library.
513
#
514
# Define BLK_SHA1 to make use of optimized C SHA-1 routines bundled
515
# with git (in the block-sha1/ directory).
516
#
517
# Define APPLE_COMMON_CRYPTO_SHA1 to use Apple's CommonCrypto for
518
# SHA-1.
519
#
520
# If don't enable any of the *_SHA1 settings in this section, Git will
521
# default to its built-in sha1collisiondetection library, which is a
522
# collision-detecting sha1 This is slower, but may detect attempted
523
# collision attacks.
524
#
525
# ==== Options for the sha1collisiondetection library ====
526
#
527
# Define DC_SHA1_EXTERNAL if you want to build / link
528
# git with the external SHA1 collision-detect library.
529
# Without this option, i.e. the default behavior is to build git with its
530
# own built-in code (or submodule).
531
#
532
# Define DC_SHA1_SUBMODULE to use the
533
# sha1collisiondetection shipped as a submodule instead of the
534
# non-submodule copy in sha1dc/. This is an experimental option used
535
# by the git project to migrate to using sha1collisiondetection as a
536
# submodule.
537
#
538
# === SHA-256 backend ===
539
#
540
# ==== Security ====
541
#
542
# Unlike SHA-1 the SHA-256 algorithm does not suffer from any known
543
# vulnerabilities, so any implementation will do.
544
#
545
# ==== SHA-256 implementations ====
546
#
547
# Define OPENSSL_SHA256 to use the SHA-256 routines in OpenSSL.
548
#
549
# Define NETTLE_SHA256 to use the SHA-256 routines in libnettle.
550
#
551
# Define GCRYPT_SHA256 to use the SHA-256 routines in libgcrypt.
552
#
553
# If don't enable any of the *_SHA256 settings in this section, Git
554
# will default to its built-in sha256 implementation.
555
#
556
# == DEVELOPER defines ==
557
#
558
# Define DEVELOPER to enable more compiler warnings. Compiler version
559
# and family are auto detected, but could be overridden by defining
560
# COMPILER_FEATURES (see config.mak.dev). You can still set
561
# CFLAGS="..." in combination with DEVELOPER enables, whether that's
562
# for tweaking something unrelated (e.g. optimization level), or for
563
# selectively overriding something DEVELOPER or one of the DEVOPTS
564
# (see just below) brings in.
565
#
566
# When DEVELOPER is set, DEVOPTS can be used to control compiler
567
# options.  This variable contains keywords separated by
568
# whitespace. The following keywords are recognized:
569
#
570
#    no-error:
571
#
572
#        suppresses the -Werror that implicitly comes with
573
#        DEVELOPER=1. Useful for getting the full set of errors
574
#        without immediately dying, or for logging them.
575
#
576
#    extra-all:
577
#
578
#        The DEVELOPER mode enables -Wextra with a few exceptions. By
579
#        setting this flag the exceptions are removed, and all of
580
#        -Wextra is used.
581
#
582
#    no-pedantic:
583
#
584
#        Disable -pedantic compilation.

### Target-specific flags and dependencies
2408

2409
# The generic compilation pattern rule and automatically
2410
# computed header dependencies (falling back to a dependency on
2411
# LIB_H) are enough to describe how most targets should be built,
2412
# but some targets are special enough to need something a little
2413
# different.
2414
#
2415
# - When a source file "foo.c" #includes a generated header file,
2416
#   we need to list that dependency for the "foo.o" target.
2417
#
2418
#   We also list it from other targets that are built from foo.c
2419
#   like "foo.sp" and "foo.s", even though that is easy to forget
2420
#   to do because the generated header is already present around
2421
#   after a regular build attempt.
2422
#
2423
# - Some code depends on configuration kept in makefile
2424
#   variables. The target-specific variable EXTRA_CPPFLAGS can
2425
#   be used to convey that information to the C preprocessor
2426
#   using -D options.
2427
#
2428
#   The "foo.o" target should have a corresponding dependency on
2429
#   a file that changes when the value of the makefile variable
2430
#   changes.  For example, targets making use of the
2431
#   $(GIT_VERSION) variable depend on GIT-VERSION-FILE.
2432
#
2433
#   Technically the ".sp" and ".s" targets do not need this
2434
#   dependency because they are force-built, but they get the
2435
#   same dependency for consistency. This way, you do not have to
2436
#   know how each target is implemented. And it means the
2437
#   dependencies here will not need to change if the force-build
2438
#   details change some day.

### Fuzz testing
3830
#
3831
# Building fuzz targets generally requires a special set of compiler flags that
3832
# are not necessarily appropriate for general builds, and that vary greatly
3833
# depending on the compiler version used.
3834
#
3835
# An example command to build against libFuzzer from LLVM 11.0.0:
3836
#
3837
# make CC=clang FUZZ_CXX=clang++ \
3838
#      CFLAGS="-fsanitize=fuzzer-no-link,address" \
3839
#      LIB_FUZZING_ENGINE="-fsanitize=fuzzer,address" \
3840
#      fuzz-all
3841
#
3842
