   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.

  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://

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

  73#
  74# Define NO_D_TYPE_IN_DIRENT if your platform defines DT_UNKNOWN but lacks
  75# d_type in struct dirent (Cygwin 1.5, fixed in Cygwin 1.7).
  76#
  77# Define HAVE_STRINGS_H if you have strings.h and need it for strcasecmp.
  78#

  86#
  87# Define NO_STRTOUMAX if you don't have both strtoimax and strtoumax in the
  88# C library. If your compiler also does not support long long or does not have
  89# strtoull, define NO_STRTOULL.
  90#
  91# Define NO_SETENV if you don't have setenv in the C library.
  92#
  93# Define NO_UNSETENV if you don't have unsetenv in the C library.
  94#

 107#
 108# Define USE_WILDMATCH if you want to use Git's wildmatch
 109# implementation as fnmatch
 110#
 111# Define NO_GECOS_IN_PWENT if you don't have pw_gecos in struct passwd
 112# in the C library.

 115#
 116# Define NEEDS_LIBGEN if your libgen needs -lgen when linking
 117#
 118# Define NO_SYS_SELECT_H if you don't have sys/select.h.
 119#
 120# Define NO_SYMLINK_HEAD if you never want .git/HEAD to be a symbolic link.
 121# Enable it on Windows.  By default, symrefs are still used.
 122#
 123# Define NO_SVN_TESTS if you want to skip time-consuming SVN interoperability
 124# tests.  These tests take up a significant amount of the total test time
 125# but are not needed unless you plan to talk to SVN repos.
 126#
 127# Define NO_FINK if you are building on Darwin/Mac OS X, have Fink
 128# installed in /sw, but don't want GIT to link against any libraries

 131# and LDFLAGS appropriately.
 132#
 133# Define NO_DARWIN_PORTS if you are building on Darwin/Mac OS X,
 134# have DarwinPorts installed in /opt/local, but don't want GIT to
 135# link against any libraries installed there.  If defined you may

 138#
 139# Define BLK_SHA1 environment variable to make use of the bundled
 140# optimized C SHA1 routine.

 167#
 168# Define NO_MMAP if you want to avoid mmap.
 169#
 170# Define NO_SYS_POLL_H if you don't have sys/poll.h.
 171#
 172# Define NO_POLL if you do not have or don't want to use poll().
 173# This also implies NO_SYS_POLL_H.
 174#
 175# Define NEEDS_SYS_PARAM_H if you need to include sys/param.h to compile,
 176# *PLEASE* REPORT to git@vger.kernel.org if your platform needs this;
 177# we want to know more about the issue.
 178#
 179# Define NO_PTHREADS if you do not have or do not want to use Pthreads.
 180#
 181# Define NO_PREAD if you have a problem with pread() system call (e.g.

 183#
 184# Define NO_SETITIMER if you don't have setitimer()
 185#
 186# Define NO_STRUCT_ITIMERVAL if you don't have struct itimerval

 189# Define NO_THREAD_SAFE_PREAD if your pread() implementation is not
 190# thread-safe. (e.g. compat/pread.c or cygwin)
 191#
 192# Define NO_FAST_WORKING_DIRECTORY if accessing objects in pack files is
 193# generally faster on your platform than accessing the working directory.

 196# the executable mode bit, but doesn't really do so.
 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

 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

 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 CYGWIN_V15_WIN32API if you are using Cygwin v1.7.x but are not
 293# using the current w32api packages. The recommended approach, however,
 294# is to update your installation if compilation errors occur.
 295#
 296# Define HAVE_DEV_TTY if your system can open /dev/tty to interact with the
 297# user.
 298#
 299# Define GETTEXT_POISON if you are debugging the choice of strings marked
 300# for translation.  In a GETTEXT_POISON build, you can turn all strings marked
 301# for translation into gibberish by setting the GIT_GETTEXT_POISON variable
 302# (to any value) in your environment.
 303#
 304# Define JSMIN to point to JavaScript minifier that functions as
 305# a filter to have gitweb.js minified.
 306#
 307# Define CSSMIN to point to a CSS minifier in order to generate a minified
 308# version of gitweb.css
 309#
 310# Define DEFAULT_PAGER to a sensible pager command (defaults to "less") if
 311# you want to use something different.  The value will be interpreted by the
 312# shell at runtime when it is used.
 313#
 314# Define DEFAULT_EDITOR to a sensible editor command (defaults to "vi") if you
 315# want to use something different.  The value will be interpreted by the shell
 316# if necessary when it is used.  Examples:
 317#
 318#   DEFAULT_EDITOR='~/bin/vi',
 319#   DEFAULT_EDITOR='$GIT_FALLBACK_EDITOR',
 320#   DEFAULT_EDITOR='"C:\Program Files\Vim\gvim.exe" --nofork'
 321#
 322# Define COMPUTE_HEADER_DEPENDENCIES to "yes" if you want dependencies on
 323# header files to be automatically computed, to avoid rebuilding objects when
 324# an unrelated header file changes.  Define it to "no" to use the hard-coded
 325# dependency rules.  The default is "auto", which means to use computed header
 326# dependencies if your compiler is detected to support it.
 327#
 328# Define CHECK_HEADER_DEPENDENCIES to check for problems in the hard-coded
 329# dependency rules.
 330#
 331# Define NATIVE_CRLF if your platform uses CRLF for line endings.
 332#
 333# Define XDL_FAST_HASH to use an alternative line-hashing method in
 334# the diff algorithm.  It gives a nice speedup if your processor has
 335# fast unaligned word loads.  Does NOT work on big-endian systems!
 336# Enabled by default on x86_64.
 337#
 338# Define GIT_USER_AGENT if you want to change how git identifies itself during
 339# network interactions.  The default is "git/$(GIT_VERSION)".
 340#
 341# Define DEFAULT_HELP_FORMAT to "man", "info" or "html"
 342# (defaults to "man") if you want to have a different default when
 343# "git help" is called without a parameter specifying the format.

1617### Target-specific flags and dependencies
1618
1619# The generic compilation pattern rule and automatically
1620# computed header dependencies (falling back to a dependency on
1621# LIB_H) are enough to describe how most targets should be built,
1622# but some targets are special enough to need something a little
1623# different.
1624#
1625# - When a source file "foo.c" #includes a generated header file,
1626#   we need to list that dependency for the "foo.o" target.
1627#
1628#   We also list it from other targets that are built from foo.c
1629#   like "foo.sp" and "foo.s", even though that is easy to forget
1630#   to do because the generated header is already present around
1631#   after a regular build attempt.
1632#
1633# - Some code depends on configuration kept in makefile
1634#   variables. The target-specific variable EXTRA_CPPFLAGS can
1635#   be used to convey that information to the C preprocessor
1636#   using -D options.
1637#
1638#   The "foo.o" target should have a corresponding dependency on
1639#   a file that changes when the value of the makefile variable
1640#   changes.  For example, targets making use of the
1641#   $(GIT_VERSION) variable depend on GIT-VERSION-FILE.
1642#
1643#   Technically the ".sp" and ".s" targets do not need this
1644#   dependency because they are force-built, but they get the
1645#   same dependency for consistency. This way, you do not have to
1646#   know how each target is implemented. And it means the
1647#   dependencies here will not need to change if the force-build
1648#   details change some day.
