   1# The default target of this Makefile is...
   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 your 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 your 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.

  31# /foo/bar/include and /foo/bar/lib directories.
  32#
  33# Define NO_CURL if you do not have libcurl installed.  git-http-fetch and
  34# git-http-push are not built, and you cannot use http:// and https://
  35# transports (neither smart nor dumb).
  36#
  37# Define CURLDIR=/foo/bar if your curl header and library files are in
  38# /foo/bar/include and /foo/bar/lib directories.
  39#

  44# /foo/bar/include and /foo/bar/lib directories.
  45#
  46# Define EXPAT_NEEDS_XMLPARSE_H if you have an old version of expat (e.g.,
  47# 1.1 or 1.2) that provides xmlparse.h instead of expat.h.
  48#
  49# Define NO_GETTEXT if you don't want Git output to be translated.
  50# A translated Git requires GNU libintl or another gettext implementation,
  51# plus libintl-perl at runtime.
  52#
  53# Define USE_GETTEXT_SCHEME and set it to 'fallthrough', if you don't trust
  54# the installed gettext translation of the shell scripts output.
  55#
  56# Define HAVE_LIBCHARSET_H if you haven't set NO_GETTEXT and you can't
  57# trust the langinfo.h's nl_langinfo(CODESET) function to return the
  58# current character set. GNU and Solaris have a nl_langinfo(CODESET),
  59# FreeBSD can use either, but MinGW and some others need to use
  60# libcharset.h's locale_charset() instead.
  61#
  62# Define CHARSET_LIB to you need to link with library other than -liconv to
  63# use locale_charset() function.  On some platforms this needs to set to
  64# -lcharset
  65#
  66# Define LIBC_CONTAINS_LIBINTL if your gettext implementation doesn't
  67# need -lintl when linking.
  68#

  75# Define NO_D_INO_IN_DIRENT if you don't have d_ino in your struct dirent.
  76#
  77# Define NO_D_TYPE_IN_DIRENT if your platform defines DT_UNKNOWN but lacks
  78# d_type in struct dirent (Cygwin 1.5, fixed in Cygwin 1.7).
  79#
  80# Define HAVE_STRINGS_H if you have strings.h and need it for strcasecmp.
  81#

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

 103#
 104# Define NO_FNMATCH if you don't have fnmatch in the C library.
 105#
 106# Define NO_FNMATCH_CASEFOLD if your fnmatch function doesn't have the
 107# FNM_CASEFOLD GNU extension.
 108#
 109# Define USE_WILDMATCH if you want to use Git's wildmatch
 110# implementation as fnmatch
 111#
 112# Define NO_GECOS_IN_PWENT if you don't have pw_gecos in struct passwd
 113# in the C library.
 114#
 115# Define NO_LIBGEN_H if you don't have libgen.h.
 116#
 117# Define NEEDS_LIBGEN if your libgen needs -lgen when linking
 118#
 119# Define NO_SYS_SELECT_H if you don't have sys/select.h.
 120#
 121# Define NO_SYMLINK_HEAD if you never want .git/HEAD to be a symbolic link.
 122# Enable it on Windows.  By default, symrefs are still used.
 123#
 124# Define NO_SVN_TESTS if you want to skip time-consuming SVN interoperability
 125# tests.  These tests take up a significant amount of the total test time
 126# but are not needed unless you plan to talk to SVN repos.
 127#
 128# Define NO_FINK if you are building on Darwin/Mac OS X, have Fink
 129# installed in /sw, but don't want GIT to link against any libraries

 131# include directories and library directories by defining CFLAGS
 132# and LDFLAGS appropriately.
 133#
 134# Define NO_DARWIN_PORTS if you are building on Darwin/Mac OS X,
 135# have DarwinPorts installed in /opt/local, but don't want GIT to
 136# link against any libraries installed there.  If defined you may
 137# specify your own (or DarwinPort's) include directories and
 138# library directories by defining CFLAGS and LDFLAGS appropriately.
 139#
 140# Define BLK_SHA1 environment variable to make use of the bundled
 141# optimized C SHA1 routine.

 159#
 160# Define NO_UINTMAX_T if you don't have uintmax_t.
 161#

 168#
 169# Define NO_MMAP if you want to avoid mmap.
 170#
 171# Define NO_SYS_POLL_H if you don't have sys/poll.h.
 172#
 173# Define NO_POLL if you do not have or don't want to use poll().
 174# This also implies NO_SYS_POLL_H.
 175#
 176# Define NEEDS_SYS_PARAM_H if you need to include sys/param.h to compile,
 177# *PLEASE* REPORT to git@vger.kernel.org if your platform needs this;
 178# we want to know more about the issue.
 179#
 180# Define NO_PTHREADS if you do not have or do not want to use Pthreads.
 181#
 182# Define NO_PREAD if you have a problem with pread() system call (e.g.

 184#
 185# Define NO_SETITIMER if you don't have setitimer()
 186#
 187# Define NO_STRUCT_ITIMERVAL if you don't have struct itimerval
 188# This also implies NO_SETITIMER

 190# Define NO_THREAD_SAFE_PREAD if your pread() implementation is not
 191# thread-safe. (e.g. compat/pread.c or cygwin)
 192#
 193# Define NO_FAST_WORKING_DIRECTORY if accessing objects in pack files is

 197# the executable mode bit, but doesn't really do so.
 198#
 199# Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
 200#
 201# Define NO_UNIX_SOCKETS if your system does not offer unix sockets.

 210#
 211# Define NO_DEFLATE_BOUND if your zlib does not have deflateBound.
 212#
 213# Define NO_R_TO_GCC_LINKER if your gcc does not like "-R/path/lib"
 214# that tells runtime paths to dynamic libraries;
 215# "-Wl,-rpath=/path/lib" is used instead.
 216#
 217# Define NO_NORETURN if using buggy versions of gcc 4.6+ and profile feedback,
 218# as the compiler can crash (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49299)
 219#
 220# Define USE_NSEC below if you want git to care about sub-second file mtimes
 221# and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
 222# it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
 223# randomly break unless your underlying filesystem supports those sub-second
 224# times (my ext3 doesn't).
 225#
 226# Define USE_ST_TIMESPEC if your "struct stat" uses "st_ctimespec" instead of
 227# "st_ctim"
 228#
 229# Define NO_NSEC if your "struct stat" does not have "st_ctim.tv_nsec"
 230# available.  This automatically turns USE_NSEC off.
 231#
 232# Define USE_STDEV below if you want git to care about the underlying device
 233# change being considered an inode change from the update-index perspective.
 234#
 235# Define NO_ST_BLOCKS_IN_STRUCT_STAT if your platform does not have st_blocks
 236# field that counts the on-disk footprint in 512-byte blocks.
 237#
 238# Define DOCBOOK_XSL_172 if you want to format man pages with DocBook XSL v1.72
 239# (not v1.73 or v1.71).
 240#
 241# Define ASCIIDOC_ROFF if your DocBook XSL does not escape raw roff directives
 242# (versions 1.68.1 through v1.72).
 243#
 244# Define GNU_ROFF if your target system uses GNU groff.  This forces
 245# apostrophes to be ASCII so that cut&pasting examples to the shell
 246# will work.
 247#
 248# Define PERL_PATH to the path of your Perl binary (usually /usr/bin/perl).
 249#
 250# Define NO_PERL_MAKEMAKER if you cannot use Makefiles generated by perl's
 251# MakeMaker (e.g. using ActiveState under Cygwin).
 252#
 253# Define NO_PERL if you do not want Perl scripts or libraries at all.
 254#
 255# Define PYTHON_PATH to the path of your Python binary (often /usr/bin/python

 257#
 258# Define NO_PYTHON if you do not want Python scripts or libraries at all.
 259#
 260# Define NO_TCLTK if you do not want Tcl/Tk GUI.
 261#
 262# The TCL_PATH variable governs the location of the Tcl interpreter
 263# used to optimize git-gui for your system.  Only used if NO_TCLTK
 264# is not set.  Defaults to the bare 'tclsh'.
 265#
 266# The TCLTK_PATH variable governs the location of the Tcl/Tk interpreter.
 267# If not set it defaults to the bare 'wish'. If it is set to the empty
 268# string then NO_TCLTK will be forced (this is used by configure script).
 269#
 270# Define INTERNAL_QSORT to use Git's implementation of qsort(), which
 271# is a simplified version of the merge sort used in glibc. This is
 272# recommended if Git triggers O(n^2) behavior in your platform's qsort().
 273#
 274# Define UNRELIABLE_FSTAT if your system's fstat does not return the same
 275# information on a not yet closed file that lstat would return for the same
 276# file after it was closed.
 277#
 278# Define OBJECT_CREATION_USES_RENAMES if your operating systems has problems
 279# when hardlinking a file to another name and unlinking the original file right
 280# away (some NTFS drivers seem to zero the contents in that scenario).
 281#
 282# Define NO_CROSS_DIRECTORY_HARDLINKS if you plan to distribute the installed
 283# programs as a tar, where bin/ and libexec/ might be on different file systems.
 284#
 285# Define NO_INSTALL_HARDLINKS if you prefer to use either symbolic links or
 286# copies to install built-in git commands e.g. git-cat-file.
 287#
 288# Define USE_NED_ALLOCATOR if you want to replace the platforms default
 289# memory allocators with the nedmalloc allocator written by Niall Douglas.
 290#
 291# Define NO_REGEX if you have no or inferior regex support in your C library.
 292#
 293# Define CYGWIN_V15_WIN32API if you are using Cygwin v1.7.x but are not
 294# using the current w32api packages. The recommended approach, however,
 295# is to update your installation if compilation errors occur.
 296#
 297# Define HAVE_DEV_TTY if your system can open /dev/tty to interact with the
 298# user.
 299#
 300# Define GETTEXT_POISON if you are debugging the choice of strings marked
 301# for translation.  In a GETTEXT_POISON build, you can turn all strings marked
 302# for translation into gibberish by setting the GIT_GETTEXT_POISON variable
 303# (to any value) in your environment.
 304#
 305# Define JSMIN to point to JavaScript minifier that functions as
 306# a filter to have gitweb.js minified.
 307#
 308# Define CSSMIN to point to a CSS minifier in order to generate a minified
 309# version of gitweb.css
 310#
 311# Define DEFAULT_PAGER to a sensible pager command (defaults to "less") if
 312# you want to use something different.  The value will be interpreted by the
 313# shell at runtime when it is used.
 314#
 315# Define DEFAULT_EDITOR to a sensible editor command (defaults to "vi") if you
 316# want to use something different.  The value will be interpreted by the shell
 317# if necessary when it is used.  Examples:
 318#
 319#   DEFAULT_EDITOR='~/bin/vi',
 320#   DEFAULT_EDITOR='$GIT_FALLBACK_EDITOR',
 321#   DEFAULT_EDITOR='"C:\Program Files\Vim\gvim.exe" --nofork'
 322#
 323# Define COMPUTE_HEADER_DEPENDENCIES to "yes" if you want dependencies on
 324# header files to be automatically computed, to avoid rebuilding objects when
 325# an unrelated header file changes.  Define it to "no" to use the hard-coded
 326# dependency rules.  The default is "auto", which means to use computed header
 327# dependencies if your compiler is detected to support it.
 328#
 329# Define CHECK_HEADER_DEPENDENCIES to check for problems in the hard-coded
 330# dependency rules.
 331#
 332# Define NATIVE_CRLF if your platform uses CRLF for line endings.
 333#
 334# Define XDL_FAST_HASH to use an alternative line-hashing method in
 335# the diff algorithm.  It gives a nice speedup if your processor has
 336# fast unaligned word loads.  Does NOT work on big-endian systems!
 337# Enabled by default on x86_64.
 338#
 339# Define GIT_USER_AGENT if you want to change how git identifies itself during
 340# network interactions.  The default is "git/$(GIT_VERSION)".
 341#
 342# Define DEFAULT_HELP_FORMAT to "man", "info" or "html"
 343# (defaults to "man") if you want to have a different default when
 344# "git help" is called without a parameter specifying the format.

1654### Target-specific flags and dependencies
1655
1656# The generic compilation pattern rule and automatically
1657# computed header dependencies (falling back to a dependency on
1658# LIB_H) are enough to describe how most targets should be built,
1659# but some targets are special enough to need something a little
1660# different.
1661#
1662# - When a source file "foo.c" #includes a generated header file,
1663#   we need to list that dependency for the "foo.o" target.
1664#
1665#   We also list it from other targets that are built from foo.c
1666#   like "foo.sp" and "foo.s", even though that is easy to forget
1667#   to do because the generated header is already present around
1668#   after a regular build attempt.
1669#
1670# - Some code depends on configuration kept in makefile
1671#   variables. The target-specific variable EXTRA_CPPFLAGS can
1672#   be used to convey that information to the C preprocessor
1673#   using -D options.
1674#
1675#   The "foo.o" target should have a corresponding dependency on
1676#   a file that changes when the value of the makefile variable
1677#   changes.  For example, targets making use of the
1678#   $(GIT_VERSION) variable depend on GIT-VERSION-FILE.
1679#
1680#   Technically the ".sp" and ".s" targets do not need this
1681#   dependency because they are force-built, but they get the
1682#   same dependency for consistency. This way, you do not have to
1683#   know how each target is implemented. And it means the
1684#   dependencies here will not need to change if the force-build
1685#   details change some day.
