   2all::
   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.
  23#
  24# Define NO_OPENSSL environment variable if you do not have OpenSSL.
  25# This also implies BLK_SHA1.
  26#
  27# Define USE_LIBPCRE if you have and want to use libpcre. git-grep will be
  28# able to use Perl-compatible regular expressions.
  29#
  30# Define LIBPCREDIR=/foo/bar if your libpcre header and library files are in
  31# /foo/bar/include and /foo/bar/lib directories.
  32#
  33# Define HAVE_ALLOCA_H if you have working alloca(3) defined in that header.
  34#
  35# Define NO_CURL if you do not have libcurl installed.  git-http-fetch and
  36# git-http-push are not built, and you cannot use http:// and https://
  37# transports (neither smart nor dumb).
  38#
  39# Define CURLDIR=/foo/bar if your curl header and library files are in
  40# /foo/bar/include and /foo/bar/lib directories.
  41#
  42# Define NO_EXPAT if you do not have expat installed.  git-http-push is
  43# not built, and you cannot push using http:// and https:// transports (dumb).
  44#
  45# Define EXPATDIR=/foo/bar if your expat header and library files are in
  46# /foo/bar/include and /foo/bar/lib directories.
  47#
  48# Define EXPAT_NEEDS_XMLPARSE_H if you have an old version of expat (e.g.,
  49# 1.1 or 1.2) that provides xmlparse.h instead of expat.h.
  50#
  51# Define NO_GETTEXT if you don't want Git output to be translated.
  52# A translated Git requires GNU libintl or another gettext implementation,
  53# plus libintl-perl at runtime.
  54#
  55# Define USE_GETTEXT_SCHEME and set it to 'fallthrough', if you don't trust
  56# the installed gettext translation of the shell scripts output.
  57#
  58# Define HAVE_LIBCHARSET_H if you haven't set NO_GETTEXT and you can't
  59# trust the langinfo.h's nl_langinfo(CODESET) function to return the
  60# current character set. GNU and Solaris have a nl_langinfo(CODESET),
  61# FreeBSD can use either, but MinGW and some others need to use
  62# libcharset.h's locale_charset() instead.
  63#
  64# Define CHARSET_LIB to the library you need to link with in order to
  65# use locale_charset() function.  On some platforms this needs to set to
  66# -lcharset, on others to -liconv .
  67#
  68# Define LIBC_CONTAINS_LIBINTL if your gettext implementation doesn't
  69# need -lintl when linking.
  70#
  71# Define NO_MSGFMT_EXTENDED_OPTIONS if your implementation of msgfmt
  72# doesn't support GNU extensions like --check and --statistics
  73#
  74# Define HAVE_PATHS_H if you have paths.h and want to use the default PATH
  75# it specifies.
  76#
  77# Define NO_D_INO_IN_DIRENT if you don't have d_ino in your struct dirent.
  78#
  79# Define NO_D_TYPE_IN_DIRENT if your platform defines DT_UNKNOWN but lacks
  80# d_type in struct dirent (Cygwin 1.5, fixed in Cygwin 1.7).
  81#
  82# Define HAVE_STRINGS_H if you have strings.h and need it for strcasecmp.
  83#
  84# Define NO_STRCASESTR if you don't have strcasestr.
  85#
  86# Define NO_MEMMEM if you don't have memmem.
  87#

  89#
  90# Define NO_STRLCPY if you don't have strlcpy.
  91#
  92# Define NO_STRTOUMAX if you don't have both strtoimax and strtoumax in the
  93# C library. If your compiler also does not support long long or does not have
  94# strtoull, define NO_STRTOULL.
  95#
  96# Define NO_SETENV if you don't have setenv in the C library.
  97#
  98# Define NO_UNSETENV if you don't have unsetenv in the C library.
  99#
 100# Define NO_MKDTEMP if you don't have mkdtemp in the C library.

 105#
 106# Define NO_GECOS_IN_PWENT if you don't have pw_gecos in struct passwd
 107# in the C library.
 108#
 109# Define NO_LIBGEN_H if you don't have libgen.h.
 110#
 111# Define NEEDS_LIBGEN if your libgen needs -lgen when linking
 112#
 113# Define NO_SYS_SELECT_H if you don't have sys/select.h.
 114#
 115# Define NO_SYMLINK_HEAD if you never want .git/HEAD to be a symbolic link.
 116# Enable it on Windows.  By default, symrefs are still used.
 117#
 118# Define NO_SVN_TESTS if you want to skip time-consuming SVN interoperability
 119# tests.  These tests take up a significant amount of the total test time
 120# but are not needed unless you plan to talk to SVN repos.
 121#
 122# Define NO_FINK if you are building on Darwin/Mac OS X, have Fink
 123# installed in /sw, but don't want GIT to link against any libraries
 124# installed there.  If defined you may specify your own (or Fink's)
 125# include directories and library directories by defining CFLAGS
 126# and LDFLAGS appropriately.
 127#
 128# Define NO_DARWIN_PORTS if you are building on Darwin/Mac OS X,
 129# have DarwinPorts installed in /opt/local, but don't want GIT to
 130# link against any libraries installed there.  If defined you may
 131# specify your own (or DarwinPort's) include directories and
 132# library directories by defining CFLAGS and LDFLAGS appropriately.
 133#
 134# Define NO_APPLE_COMMON_CRYPTO if you are building on Darwin/Mac OS X
 135# and do not want to use Apple's CommonCrypto library.  This allows you
 136# to provide your own OpenSSL library, for example from MacPorts.
 137#
 138# Define BLK_SHA1 environment variable to make use of the bundled
 139# optimized C SHA1 routine.
 140#
 141# Define PPC_SHA1 environment variable when running make to make use of
 142# a bundled SHA1 routine optimized for PowerPC.
 143#
 144# Define NEEDS_CRYPTO_WITH_SSL if you need -lcrypto when using -lssl (Darwin).
 145#
 146# Define NEEDS_SSL_WITH_CRYPTO if you need -lssl when using -lcrypto (Darwin).
 147#
 148# Define NEEDS_SSL_WITH_CURL if you need -lssl with -lcurl (Minix).
 149#
 150# Define NEEDS_IDN_WITH_CURL if you need -lidn when using -lcurl (Minix).
 151#
 152# Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
 153#
 154# Define NEEDS_LIBINTL_BEFORE_LIBICONV if you need libintl before libiconv.
 155#
 156# Define NO_INTPTR_T if you don't have intptr_t or uintptr_t.
 157#
 158# Define NO_UINTMAX_T if you don't have uintmax_t.
 159#
 160# Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
 161# Patrick Mauritz).
 162#
 163# Define NEEDS_RESOLV if linking with -lnsl and/or -lsocket is not enough.
 164# Notably on Solaris hstrerror resides in libresolv and on Solaris 7
 165# inet_ntop and inet_pton additionally reside there.
 166#
 167# Define NO_MMAP if you want to avoid mmap.
 168#
 169# Define NO_SYS_POLL_H if you don't have sys/poll.h.
 170#
 171# Define NO_POLL if you do not have or don't want to use poll().
 172# This also implies NO_SYS_POLL_H.
 173#
 174# Define NEEDS_SYS_PARAM_H if you need to include sys/param.h to compile,
 175# *PLEASE* REPORT to git@vger.kernel.org if your platform needs this;
 176# we want to know more about the issue.
 177#
 178# Define NO_PTHREADS if you do not have or do not want to use Pthreads.
 179#
 180# Define NO_PREAD if you have a problem with pread() system call (e.g.
 181# cygwin1.dll before v1.5.22).
 182#
 183# Define NO_SETITIMER if you don't have setitimer()
 184#
 185# Define NO_STRUCT_ITIMERVAL if you don't have struct itimerval
 186# This also implies NO_SETITIMER
 187#
 188# Define NO_FAST_WORKING_DIRECTORY if accessing objects in pack files is
 189# generally faster on your platform than accessing the working directory.
 190#
 191# Define NO_TRUSTABLE_FILEMODE if your filesystem may claim to support
 192# the executable mode bit, but doesn't really do so.
 193#
 194# Define NEEDS_MODE_TRANSLATION if your OS strays from the typical file type
 195# bits in mode values (e.g. z/OS defines I_SFMT to 0xFF000000 as opposed to the
 196# usual 0xF000).
 197#
 198# Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
 199#
 200# Define NO_UNIX_SOCKETS if your system does not offer unix sockets.
 201#
 202# Define NO_SOCKADDR_STORAGE if your platform does not have struct
 203# sockaddr_storage.
 204#
 205# Define NO_ICONV if your libc does not properly support iconv.
 206#
 207# Define OLD_ICONV if your library has an old iconv(), where the second
 208# (input buffer pointer) parameter is declared with type (const char **).
 209#
 210# Define NO_DEFLATE_BOUND if your zlib does not have deflateBound.
 211#
 212# Define NO_R_TO_GCC_LINKER if your gcc does not like "-R/path/lib"
 213# that tells runtime paths to dynamic libraries;
 214# "-Wl,-rpath=/path/lib" is used instead.
 215#
 216# Define NO_NORETURN if using buggy versions of gcc 4.6+ and profile feedback,
 217# as the compiler can crash (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49299)
 218#
 219# Define USE_NSEC below if you want git to care about sub-second file mtimes
 220# and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
 221# it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
 222# randomly break unless your underlying filesystem supports those sub-second
 223# times (my ext3 doesn't).
 224#
 225# Define USE_ST_TIMESPEC if your "struct stat" uses "st_ctimespec" instead of
 226# "st_ctim"
 227#
 228# Define NO_NSEC if your "struct stat" does not have "st_ctim.tv_nsec"
 229# available.  This automatically turns USE_NSEC off.
 230#
 231# Define USE_STDEV below if you want git to care about the underlying device
 232# change being considered an inode change from the update-index perspective.
 233#
 234# Define NO_ST_BLOCKS_IN_STRUCT_STAT if your platform does not have st_blocks
 235# field that counts the on-disk footprint in 512-byte blocks.
 236#
 237# Define DOCBOOK_XSL_172 if you want to format man pages with DocBook XSL v1.72
 238# (not v1.73 or v1.71).
 239#
 240# Define ASCIIDOC_ROFF if your DocBook XSL does not escape raw roff directives
 241# (versions 1.68.1 through v1.72).
 242#
 243# Define GNU_ROFF if your target system uses GNU groff.  This forces
 244# apostrophes to be ASCII so that cut&pasting examples to the shell
 245# will work.
 246#
 247# Define PERL_PATH to the path of your Perl binary (usually /usr/bin/perl).
 248#
 249# Define NO_PERL_MAKEMAKER if you cannot use Makefiles generated by perl's
 250# MakeMaker (e.g. using ActiveState under Cygwin).
 251#
 252# Define NO_PERL if you do not want Perl scripts or libraries at all.
 253#
 254# Define PYTHON_PATH to the path of your Python binary (often /usr/bin/python
 255# but /usr/bin/python2.7 on some platforms).
 256#
 257# Define NO_PYTHON if you do not want Python scripts or libraries at all.
 258#
 259# Define NO_TCLTK if you do not want Tcl/Tk GUI.
 260#
 261# The TCL_PATH variable governs the location of the Tcl interpreter
 262# used to optimize git-gui for your system.  Only used if NO_TCLTK
 263# is not set.  Defaults to the bare 'tclsh'.
 264#
 265# The TCLTK_PATH variable governs the location of the Tcl/Tk interpreter.
 266# If not set it defaults to the bare 'wish'. If it is set to the empty
 267# string then NO_TCLTK will be forced (this is used by configure script).
 268#
 269# Define INTERNAL_QSORT to use Git's implementation of qsort(), which
 270# is a simplified version of the merge sort used in glibc. This is
 271# recommended if Git triggers O(n^2) behavior in your platform's qsort().
 272#
 273# Define UNRELIABLE_FSTAT if your system's fstat does not return the same
 274# information on a not yet closed file that lstat would return for the same
 275# file after it was closed.
 276#
 277# Define OBJECT_CREATION_USES_RENAMES if your operating systems has problems
 278# when hardlinking a file to another name and unlinking the original file right
 279# away (some NTFS drivers seem to zero the contents in that scenario).
 280#
 281# Define NO_CROSS_DIRECTORY_HARDLINKS if you plan to distribute the installed
 282# programs as a tar, where bin/ and libexec/ might be on different file systems.
 283#
 284# Define NO_INSTALL_HARDLINKS if you prefer to use either symbolic links or
 285# copies to install built-in git commands e.g. git-cat-file.
 286#
 287# Define USE_NED_ALLOCATOR if you want to replace the platforms default
 288# memory allocators with the nedmalloc allocator written by Niall Douglas.
 289#
 290# Define NO_REGEX if you have no or inferior regex support in your C library.
 291#
 292# Define HAVE_DEV_TTY if your system can open /dev/tty to interact with the
 293# user.
 294#
 295# Define GETTEXT_POISON if you are debugging the choice of strings marked
 296# for translation.  In a GETTEXT_POISON build, you can turn all strings marked
 297# for translation into gibberish by setting the GIT_GETTEXT_POISON variable
 298# (to any value) in your environment.
 299#
 300# Define JSMIN to point to JavaScript minifier that functions as
 301# a filter to have gitweb.js minified.
 302#
 303# Define CSSMIN to point to a CSS minifier in order to generate a minified
 304# version of gitweb.css
 305#
 306# Define DEFAULT_PAGER to a sensible pager command (defaults to "less") if
 307# you want to use something different.  The value will be interpreted by the
 308# shell at runtime when it is used.
 309#
 310# Define DEFAULT_EDITOR to a sensible editor command (defaults to "vi") if you
 311# want to use something different.  The value will be interpreted by the shell
 312# if necessary when it is used.  Examples:
 313#
 314#   DEFAULT_EDITOR='~/bin/vi',
 315#   DEFAULT_EDITOR='$GIT_FALLBACK_EDITOR',
 316#   DEFAULT_EDITOR='"C:\Program Files\Vim\gvim.exe" --nofork'
 317#
 318# Define COMPUTE_HEADER_DEPENDENCIES to "yes" if you want dependencies on
 319# header files to be automatically computed, to avoid rebuilding objects when
 320# an unrelated header file changes.  Define it to "no" to use the hard-coded
 321# dependency rules.  The default is "auto", which means to use computed header
 322# dependencies if your compiler is detected to support it.
 323#
 324# Define NATIVE_CRLF if your platform uses CRLF for line endings.
 325#
 326# Define XDL_FAST_HASH to use an alternative line-hashing method in
 327# the diff algorithm.  It gives a nice speedup if your processor has
 328# fast unaligned word loads.  Does NOT work on big-endian systems!
 329# Enabled by default on x86_64.
 330#
 331# Define GIT_USER_AGENT if you want to change how git identifies itself during
 332# network interactions.  The default is "git/$(GIT_VERSION)".
 333#
 334# Define DEFAULT_HELP_FORMAT to "man", "info" or "html"
 335# (defaults to "man") if you want to have a different default when
 336# "git help" is called without a parameter specifying the format.
 337#
 338# Define TEST_GIT_INDEX_VERSION to 2, 3 or 4 to run the test suite
 339# with a different indexfile format version.  If it isn't set the index
 340# file format used is index-v[23].
 341#
 342# Define GMTIME_UNRELIABLE_ERRORS if your gmtime() function does not
 343# return NULL when it receives a bogus time_t.
 344#
 345# Define HAVE_CLOCK_GETTIME if your platform has clock_gettime in librt.

1581### Target-specific flags and dependencies
1582
1583# The generic compilation pattern rule and automatically
1584# computed header dependencies (falling back to a dependency on
1585# LIB_H) are enough to describe how most targets should be built,
1586# but some targets are special enough to need something a little
1587# different.
1588#
1589# - When a source file "foo.c" #includes a generated header file,
1590#   we need to list that dependency for the "foo.o" target.
1591#
1592#   We also list it from other targets that are built from foo.c
1593#   like "foo.sp" and "foo.s", even though that is easy to forget
1594#   to do because the generated header is already present around
1595#   after a regular build attempt.
1596#
1597# - Some code depends on configuration kept in makefile
1598#   variables. The target-specific variable EXTRA_CPPFLAGS can
1599#   be used to convey that information to the C preprocessor
1600#   using -D options.
1601#
1602#   The "foo.o" target should have a corresponding dependency on
1603#   a file that changes when the value of the makefile variable
1604#   changes.  For example, targets making use of the
1605#   $(GIT_VERSION) variable depend on GIT-VERSION-FILE.
1606#
1607#   Technically the ".sp" and ".s" targets do not need this
1608#   dependency because they are force-built, but they get the
1609#   same dependency for consistency. This way, you do not have to
1610#   know how each target is implemented. And it means the
1611#   dependencies here will not need to change if the force-build
1612#   details change some day.
