[git/git.git] / Makefile
1 # The default target of this Makefile is...
2 all::
3
4 # Define V=1 to have a more verbose compile.
5 #
6 # Define SHELL_PATH to a POSIX shell if your /bin/sh is broken.
7 #
8 # Define SANE_TOOL_PATH to a colon-separated list of paths to prepend
9 # to PATH if your tools in /usr/bin are broken.
10 #
11 # Define SOCKLEN_T to a suitable type (such as 'size_t') if your
12 # system headers do not define a socklen_t type.
13 #
14 # Define INLINE to a suitable substitute (such as '__inline' or '') if git
15 # fails to compile with errors about undefined inline functions or similar.
16 #
17 # Define SNPRINTF_RETURNS_BOGUS if you are on a system which snprintf()
18 # or vsnprintf() return -1 instead of number of characters which would
19 # have been written to the final string if enough space had been available.
20 #
21 # Define FREAD_READS_DIRECTORIES if you are on a system which succeeds
22 # when attempting to read from an fopen'ed directory (or even to fopen
23 # it at all).
24 #
25 # Define NO_OPENSSL environment variable if you do not have OpenSSL.
26 #
27 # Define USE_LIBPCRE if you have and want to use libpcre. Various
28 # commands such as log and grep offer runtime options to use
29 # Perl-compatible regular expressions instead of standard or extended
30 # POSIX regular expressions.
31 #
32 # Currently USE_LIBPCRE is a synonym for USE_LIBPCRE1, define
33 # USE_LIBPCRE2 instead if you'd like to use version 2 of the PCRE
34 # library. The USE_LIBPCRE flag will likely be changed to mean v2 by
35 # default in future releases.
36 #
37 # When using USE_LIBPCRE1, define NO_LIBPCRE1_JIT if the PCRE v1
38 # library is compiled without --enable-jit. We will auto-detect
39 # whether the version of the PCRE v1 library in use has JIT support at
40 # all, but we unfortunately can't auto-detect whether JIT support
41 # hasn't been compiled in in an otherwise JIT-supporting version. If
42 # you have link-time errors about a missing `pcre_jit_exec` define
43 # this, or recompile PCRE v1 with --enable-jit.
44 #
45 # Define LIBPCREDIR=/foo/bar if your PCRE header and library files are
46 # in /foo/bar/include and /foo/bar/lib directories. Which version of
47 # PCRE this points to determined by the USE_LIBPCRE1 and USE_LIBPCRE2
48 # variables.
49 #
50 # Define HAVE_ALLOCA_H if you have working alloca(3) defined in that header.
51 #
52 # Define NO_CURL if you do not have libcurl installed. git-http-fetch and
53 # git-http-push are not built, and you cannot use http:// and https://
54 # transports (neither smart nor dumb).
55 #
56 # Define CURLDIR=/foo/bar if your curl header and library files are in
57 # /foo/bar/include and /foo/bar/lib directories.
58 #
59 # Define CURL_CONFIG to curl's configuration program that prints information
60 # about the library (e.g., its version number). The default is 'curl-config'.
61 #
62 # Define NO_EXPAT if you do not have expat installed. git-http-push is
63 # not built, and you cannot push using http:// and https:// transports (dumb).
64 #
65 # Define EXPATDIR=/foo/bar if your expat header and library files are in
66 # /foo/bar/include and /foo/bar/lib directories.
67 #
68 # Define EXPAT_NEEDS_XMLPARSE_H if you have an old version of expat (e.g.,
69 # 1.1 or 1.2) that provides xmlparse.h instead of expat.h.
70 #
71 # Define NO_GETTEXT if you don't want Git output to be translated.
72 # A translated Git requires GNU libintl or another gettext implementation,
73 # plus libintl-perl at runtime.
74 #
75 # Define USE_GETTEXT_SCHEME and set it to 'fallthrough', if you don't trust
76 # the installed gettext translation of the shell scripts output.
77 #
78 # Define HAVE_LIBCHARSET_H if you haven't set NO_GETTEXT and you can't
79 # trust the langinfo.h's nl_langinfo(CODESET) function to return the
80 # current character set. GNU and Solaris have a nl_langinfo(CODESET),
81 # FreeBSD can use either, but MinGW and some others need to use
82 # libcharset.h's locale_charset() instead.
83 #
84 # Define CHARSET_LIB to the library you need to link with in order to
85 # use locale_charset() function. On some platforms this needs to set to
86 # -lcharset, on others to -liconv .
87 #
88 # Define LIBC_CONTAINS_LIBINTL if your gettext implementation doesn't
89 # need -lintl when linking.
90 #
91 # Define NO_MSGFMT_EXTENDED_OPTIONS if your implementation of msgfmt
92 # doesn't support GNU extensions like --check and --statistics
93 #
94 # Define HAVE_PATHS_H if you have paths.h and want to use the default PATH
95 # it specifies.
96 #
97 # Define NO_D_TYPE_IN_DIRENT if your platform defines DT_UNKNOWN but lacks
98 # d_type in struct dirent (Cygwin 1.5, fixed in Cygwin 1.7).
99 #
100 # Define HAVE_STRINGS_H if you have strings.h and need it for strcasecmp.
101 #
102 # Define NO_STRCASESTR if you don't have strcasestr.
103 #
104 # Define NO_MEMMEM if you don't have memmem.
105 #
106 # Define NO_GETPAGESIZE if you don't have getpagesize.
107 #
108 # Define NO_STRLCPY if you don't have strlcpy.
109 #
110 # Define NO_STRTOUMAX if you don't have both strtoimax and strtoumax in the
111 # C library. If your compiler also does not support long long or does not have
112 # strtoull, define NO_STRTOULL.
113 #
114 # Define NO_SETENV if you don't have setenv in the C library.
115 #
116 # Define NO_UNSETENV if you don't have unsetenv in the C library.
117 #
118 # Define NO_MKDTEMP if you don't have mkdtemp in the C library.
119 #
120 # Define MKDIR_WO_TRAILING_SLASH if your mkdir() can't deal with trailing slash.
121 #
122 # Define NO_GECOS_IN_PWENT if you don't have pw_gecos in struct passwd
123 # in the C library.
124 #
125 # Define NO_LIBGEN_H if you don't have libgen.h.
126 #
127 # Define NEEDS_LIBGEN if your libgen needs -lgen when linking
128 #
129 # Define NO_SYS_SELECT_H if you don't have sys/select.h.
130 #
131 # Define NO_SYMLINK_HEAD if you never want .git/HEAD to be a symbolic link.
132 # Enable it on Windows. By default, symrefs are still used.
133 #
134 # Define NO_SVN_TESTS if you want to skip time-consuming SVN interoperability
135 # tests. These tests take up a significant amount of the total test time
136 # but are not needed unless you plan to talk to SVN repos.
137 #
138 # Define NO_FINK if you are building on Darwin/Mac OS X, have Fink
139 # installed in /sw, but don't want GIT to link against any libraries
140 # installed there. If defined you may specify your own (or Fink's)
141 # include directories and library directories by defining CFLAGS
142 # and LDFLAGS appropriately.
143 #
144 # Define NO_DARWIN_PORTS if you are building on Darwin/Mac OS X,
145 # have DarwinPorts installed in /opt/local, but don't want GIT to
146 # link against any libraries installed there. If defined you may
147 # specify your own (or DarwinPort's) include directories and
148 # library directories by defining CFLAGS and LDFLAGS appropriately.
149 #
150 # Define NO_APPLE_COMMON_CRYPTO if you are building on Darwin/Mac OS X
151 # and do not want to use Apple's CommonCrypto library. This allows you
152 # to provide your own OpenSSL library, for example from MacPorts.
153 #
154 # Define BLK_SHA1 environment variable to make use of the bundled
155 # optimized C SHA1 routine.
156 #
157 # Define PPC_SHA1 environment variable when running make to make use of
158 # a bundled SHA1 routine optimized for PowerPC.
159 #
160 # Define DC_SHA1 to unconditionally enable the collision-detecting sha1
161 # algorithm. This is slower, but may detect attempted collision attacks.
162 # Takes priority over other *_SHA1 knobs.
163 #
164 # Define DC_SHA1_EXTERNAL in addition to DC_SHA1 if you want to build / link
165 # git with the external SHA1 collision-detect library.
166 # Without this option, i.e. the default behavior is to build git with its
167 # own built-in code (or submodule).
168 #
169 # Define DC_SHA1_SUBMODULE in addition to DC_SHA1 to use the
170 # sha1collisiondetection shipped as a submodule instead of the
171 # non-submodule copy in sha1dc/. This is an experimental option used
172 # by the git project to migrate to using sha1collisiondetection as a
173 # submodule.
174 #
175 # Define OPENSSL_SHA1 environment variable when running make to link
176 # with the SHA1 routine from openssl library.
177 #
178 # Define SHA1_MAX_BLOCK_SIZE to limit the amount of data that will be hashed
179 # in one call to the platform's SHA1_Update(). e.g. APPLE_COMMON_CRYPTO
180 # wants 'SHA1_MAX_BLOCK_SIZE=1024L*1024L*1024L' defined.
181 #
182 # Define NEEDS_CRYPTO_WITH_SSL if you need -lcrypto when using -lssl (Darwin).
183 #
184 # Define NEEDS_SSL_WITH_CRYPTO if you need -lssl when using -lcrypto (Darwin).
185 #
186 # Define NEEDS_SSL_WITH_CURL if you need -lssl with -lcurl (Minix).
187 #
188 # Define NEEDS_IDN_WITH_CURL if you need -lidn when using -lcurl (Minix).
189 #
190 # Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
191 #
192 # Define NEEDS_LIBINTL_BEFORE_LIBICONV if you need libintl before libiconv.
193 #
194 # Define NO_INTPTR_T if you don't have intptr_t or uintptr_t.
195 #
196 # Define NO_UINTMAX_T if you don't have uintmax_t.
197 #
198 # Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
199 # Patrick Mauritz).
200 #
201 # Define NEEDS_RESOLV if linking with -lnsl and/or -lsocket is not enough.
202 # Notably on Solaris hstrerror resides in libresolv and on Solaris 7
203 # inet_ntop and inet_pton additionally reside there.
204 #
205 # Define NO_MMAP if you want to avoid mmap.
206 #
207 # Define MMAP_PREVENTS_DELETE if a file that is currently mmapped cannot be
208 # deleted or cannot be replaced using rename().
209 #
210 # Define NO_SYS_POLL_H if you don't have sys/poll.h.
211 #
212 # Define NO_POLL if you do not have or don't want to use poll().
213 # This also implies NO_SYS_POLL_H.
214 #
215 # Define NEEDS_SYS_PARAM_H if you need to include sys/param.h to compile,
216 # *PLEASE* REPORT to git@vger.kernel.org if your platform needs this;
217 # we want to know more about the issue.
218 #
219 # Define NO_PTHREADS if you do not have or do not want to use Pthreads.
220 #
221 # Define NO_PREAD if you have a problem with pread() system call (e.g.
222 # cygwin1.dll before v1.5.22).
223 #
224 # Define NO_SETITIMER if you don't have setitimer()
225 #
226 # Define NO_STRUCT_ITIMERVAL if you don't have struct itimerval
227 # This also implies NO_SETITIMER
228 #
229 # Define NO_FAST_WORKING_DIRECTORY if accessing objects in pack files is
230 # generally faster on your platform than accessing the working directory.
231 #
232 # Define NO_TRUSTABLE_FILEMODE if your filesystem may claim to support
233 # the executable mode bit, but doesn't really do so.
234 #
235 # Define NEEDS_MODE_TRANSLATION if your OS strays from the typical file type
236 # bits in mode values (e.g. z/OS defines I_SFMT to 0xFF000000 as opposed to the
237 # usual 0xF000).
238 #
239 # Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
240 #
241 # Define NO_UNIX_SOCKETS if your system does not offer unix sockets.
242 #
243 # Define NO_SOCKADDR_STORAGE if your platform does not have struct
244 # sockaddr_storage.
245 #
246 # Define NO_ICONV if your libc does not properly support iconv.
247 #
248 # Define OLD_ICONV if your library has an old iconv(), where the second
249 # (input buffer pointer) parameter is declared with type (const char **).
250 #
251 # Define NO_DEFLATE_BOUND if your zlib does not have deflateBound.
252 #
253 # Define NO_R_TO_GCC_LINKER if your gcc does not like "-R/path/lib"
254 # that tells runtime paths to dynamic libraries;
255 # "-Wl,-rpath=/path/lib" is used instead.
256 #
257 # Define NO_NORETURN if using buggy versions of gcc 4.6+ and profile feedback,
258 # as the compiler can crash (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49299)
259 #
260 # Define USE_NSEC below if you want git to care about sub-second file mtimes
261 # and ctimes. Note that you need recent glibc (at least 2.2.4) for this. On
262 # Linux, kernel 2.6.11 or newer is required for reliable sub-second file times
263 # on file systems with exactly 1 ns or 1 s resolution. If you intend to use Git
264 # on other file systems (e.g. CEPH, CIFS, NTFS, UDF), don't enable USE_NSEC. See
265 # Documentation/technical/racy-git.txt for details.
266 #
267 # Define USE_ST_TIMESPEC if your "struct stat" uses "st_ctimespec" instead of
268 # "st_ctim"
269 #
270 # Define NO_NSEC if your "struct stat" does not have "st_ctim.tv_nsec"
271 # available. This automatically turns USE_NSEC off.
272 #
273 # Define USE_STDEV below if you want git to care about the underlying device
274 # change being considered an inode change from the update-index perspective.
275 #
276 # Define NO_ST_BLOCKS_IN_STRUCT_STAT if your platform does not have st_blocks
277 # field that counts the on-disk footprint in 512-byte blocks.
278 #
279 # Define DOCBOOK_XSL_172 if you want to format man pages with DocBook XSL v1.72
280 # (not v1.73 or v1.71).
281 #
282 # Define ASCIIDOC_ROFF if your DocBook XSL does not escape raw roff directives
283 # (versions 1.68.1 through v1.72).
284 #
285 # Define GNU_ROFF if your target system uses GNU groff. This forces
286 # apostrophes to be ASCII so that cut&pasting examples to the shell
287 # will work.
288 #
289 # Define USE_ASCIIDOCTOR to use Asciidoctor instead of AsciiDoc to build the
290 # documentation.
291 #
292 # Define ASCIIDOCTOR_EXTENSIONS_LAB to point to the location of the Asciidoctor
293 # Extensions Lab if you have it available.

295 # Define PERL_PATH to the path of your Perl binary (usually /usr/bin/perl).
296 #
297 # Define NO_PERL if you do not want Perl scripts or libraries at all.
298 #
299 # Define NO_PERL_CPAN_FALLBACKS if you do not want to install bundled
300 # copies of CPAN modules that serve as a fallback in case the modules
301 # are not available on the system. This option is intended for
302 # distributions that want to use their packaged versions of Perl
303 # modules, instead of the fallbacks shipped with Git.
304 #
305 # Define PYTHON_PATH to the path of your Python binary (often /usr/bin/python
306 # but /usr/bin/python2.7 on some platforms).
307 #
308 # Define NO_PYTHON if you do not want Python scripts or libraries at all.
309 #
310 # Define NO_TCLTK if you do not want Tcl/Tk GUI.
311 #
312 # Define SANE_TEXT_GREP to "-a" if you use recent versions of GNU grep
313 # and egrep that are pickier when their input contains non-ASCII data.
314 #
315 # The TCL_PATH variable governs the location of the Tcl interpreter
316 # used to optimize git-gui for your system. Only used if NO_TCLTK
317 # is not set. Defaults to the bare 'tclsh'.
318 #
319 # The TCLTK_PATH variable governs the location of the Tcl/Tk interpreter.
320 # If not set it defaults to the bare 'wish'. If it is set to the empty
321 # string then NO_TCLTK will be forced (this is used by configure script).
322 #
323 # Define INTERNAL_QSORT to use Git's implementation of qsort(), which
324 # is a simplified version of the merge sort used in glibc. This is
325 # recommended if Git triggers O(n^2) behavior in your platform's qsort().
326 #
327 # Define HAVE_ISO_QSORT_S if your platform provides a qsort_s() that's
328 # compatible with the one described in C11 Annex K.
329 #
330 # Define UNRELIABLE_FSTAT if your system's fstat does not return the same
331 # information on a not yet closed file that lstat would return for the same
332 # file after it was closed.
333 #
334 # Define OBJECT_CREATION_USES_RENAMES if your operating systems has problems
335 # when hardlinking a file to another name and unlinking the original file right
336 # away (some NTFS drivers seem to zero the contents in that scenario).
337 #
338 # Define NO_CROSS_DIRECTORY_HARDLINKS if you plan to distribute the installed
339 # programs as a tar, where bin/ and libexec/ might be on different file systems.
340 #
341 # Define NO_INSTALL_HARDLINKS if you prefer to use either symbolic links or
342 # copies to install built-in git commands e.g. git-cat-file.
343 #
344 # Define USE_NED_ALLOCATOR if you want to replace the platforms default
345 # memory allocators with the nedmalloc allocator written by Niall Douglas.
346 #
347 # Define OVERRIDE_STRDUP to override the libc version of strdup(3).
348 # This is necessary when using a custom allocator in order to avoid
349 # crashes due to allocation and free working on different 'heaps'.
350 # It's defined automatically if USE_NED_ALLOCATOR is set.
351 #
352 # Define NO_REGEX if your C library lacks regex support with REG_STARTEND
353 # feature.
354 #
355 # Define HAVE_DEV_TTY if your system can open /dev/tty to interact with the
356 # user.
357 #
358 # Define GETTEXT_POISON if you are debugging the choice of strings marked

362 #
363 # Define JSMIN to point to JavaScript minifier that functions as
364 # a filter to have gitweb.js minified.
365 #
366 # Define CSSMIN to point to a CSS minifier in order to generate a minified
367 # version of gitweb.css
368 #
369 # Define DEFAULT_PAGER to a sensible pager command (defaults to "less") if
370 # you want to use something different. The value will be interpreted by the
371 # shell at runtime when it is used.
372 #
373 # Define DEFAULT_EDITOR to a sensible editor command (defaults to "vi") if you
374 # want to use something different. The value will be interpreted by the shell
375 # if necessary when it is used. Examples:
376 #
377 # DEFAULT_EDITOR='~/bin/vi',
378 # DEFAULT_EDITOR='$GIT_FALLBACK_EDITOR',
379 # DEFAULT_EDITOR='"C:\Program Files\Vim\gvim.exe" --nofork'
380 #
381 # Define COMPUTE_HEADER_DEPENDENCIES to "yes" if you want dependencies on
382 # header files to be automatically computed, to avoid rebuilding objects when
383 # an unrelated header file changes. Define it to "no" to use the hard-coded
384 # dependency rules. The default is "auto", which means to use computed header
385 # dependencies if your compiler is detected to support it.
386 #
387 # Define NATIVE_CRLF if your platform uses CRLF for line endings.
388 #
389 # Define GIT_USER_AGENT if you want to change how git identifies itself during
390 # network interactions. The default is "git/$(GIT_VERSION)".
391 #
392 # Define DEFAULT_HELP_FORMAT to "man", "info" or "html"
393 # (defaults to "man") if you want to have a different default when
394 # "git help" is called without a parameter specifying the format.
395 #
396 # Define TEST_GIT_INDEX_VERSION to 2, 3 or 4 to run the test suite
397 # with a different indexfile format version. If it isn't set the index
398 # file format used is index-v[23].
399 #
400 # Define GMTIME_UNRELIABLE_ERRORS if your gmtime() function does not
401 # return NULL when it receives a bogus time_t.
402 #
403 # Define HAVE_CLOCK_GETTIME if your platform has clock_gettime.
404 #
405 # Define HAVE_CLOCK_MONOTONIC if your platform has CLOCK_MONOTONIC.

407 # Define NEEDS_LIBRT if your platform requires linking with librt (glibc version
408 # before 2.17) for clock_gettime and CLOCK_MONOTONIC.
409 #
410 # Define USE_PARENS_AROUND_GETTEXT_N to "yes" if your compiler happily
411 # compiles the following initialization:
412 #
413 # static const char s[] = ("FOO");
414 #
415 # and define it to "no" if you need to remove the parentheses () around the
416 # constant. The default is "auto", which means to use parentheses if your
417 # compiler is detected to support it.
418 #
419 # Define HAVE_BSD_SYSCTL if your platform has a BSD-compatible sysctl function.
420 #
421 # Define HAVE_GETDELIM if your system has the getdelim() function.
422 #
423 # Define PAGER_ENV to a SP separated VAR=VAL pairs to define
424 # default environment variables to be passed when a pager is spawned, e.g.
425 #
426 # PAGER_ENV = LESS=FRX LV=-c
427 #
428 # to say "export LESS=FRX (and LV=-c) if the environment variable
429 # LESS (and LV) is not set, respectively".
430 #
431 # Define TEST_SHELL_PATH if you want to use a shell besides SHELL_PATH for
432 # running the test scripts (e.g., bash has better support for "set -x"
433 # tracing).
434 #
435 # When cross-compiling, define HOST_CPU as the canonical name of the CPU on

1862 ### Target-specific flags and dependencies
1863
1864 # The generic compilation pattern rule and automatically
1865 # computed header dependencies (falling back to a dependency on
1866 # LIB_H) are enough to describe how most targets should be built,
1867 # but some targets are special enough to need something a little
1868 # different.
1869 #
1870 # - When a source file "foo.c" #includes a generated header file,
1871 # we need to list that dependency for the "foo.o" target.
1872 #
1873 # We also list it from other targets that are built from foo.c
1874 # like "foo.sp" and "foo.s", even though that is easy to forget
1875 # to do because the generated header is already present around
1876 # after a regular build attempt.
1877 #
1878 # - Some code depends on configuration kept in makefile
1879 # variables. The target-specific variable EXTRA_CPPFLAGS can
1880 # be used to convey that information to the C preprocessor
1881 # using -D options.
1882 #
1883 # The "foo.o" target should have a corresponding dependency on
1884 # a file that changes when the value of the makefile variable
1885 # changes. For example, targets making use of the
1886 # $(GIT_VERSION) variable depend on GIT-VERSION-FILE.
1887 #
1888 # Technically the ".sp" and ".s" targets do not need this
1889 # dependency because they are force-built, but they get the
1890 # same dependency for consistency. This way, you do not have to
1891 # know how each target is implemented. And it means the
1892 # dependencies here will not need to change if the force-build
1893 # details change some day.
