   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#

   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.

  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#

  54# trust the langinfo.h's nl_langinfo(CODESET) function to return the

  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.

  76#
  77# Define HAVE_STRINGS_H if you have strings.h and need it for strcasecmp.

  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.

 107#
 108# Define NO_GECOS_IN_PWENT if you don't have pw_gecos in struct passwd
 109# in the C library.
 110#
 111# Define NO_LIBGEN_H if you don't have libgen.h.

 114#
 115# Define NO_SYS_SELECT_H if you don't have sys/select.h.
 116#
 117# Define NO_SYMLINK_HEAD if you never want .git/HEAD to be a symbolic link.
 118# Enable it on Windows.  By default, symrefs are still used.
 119#
 120# Define NO_SVN_TESTS if you want to skip time-consuming SVN interoperability
 121# tests.  These tests take up a significant amount of the total test time
 122# but are not needed unless you plan to talk to SVN repos.
 123#
 124# Define NO_FINK if you are building on Darwin/Mac OS X, have Fink
 125# installed in /sw, but don't want GIT to link against any libraries

 127# include directories and library directories by defining CFLAGS
 128# and LDFLAGS appropriately.
 129#
 130# Define NO_DARWIN_PORTS if you are building on Darwin/Mac OS X,
 131# have DarwinPorts installed in /opt/local, but don't want GIT to

 133# specify your own (or DarwinPort's) include directories and
 134# library directories by defining CFLAGS and LDFLAGS appropriately.
 135#
 136# Define BLK_SHA1 environment variable to make use of the bundled
 137# optimized C SHA1 routine.

 166#
 167# Define NO_SYS_POLL_H if you don't have sys/poll.h.

 170# This also implies NO_SYS_POLL_H.
 171#
 172# Define NEEDS_SYS_PARAM_H if you need to include sys/param.h to compile,
 173# *PLEASE* REPORT to git@vger.kernel.org if your platform needs this;
 174# we want to know more about the issue.
 175#
 176# Define NO_PTHREADS if you do not have or do not want to use Pthreads.
 177#

 187# thread-safe. (e.g. compat/pread.c or cygwin)
 188#
 189# Define NO_FAST_WORKING_DIRECTORY if accessing objects in pack files is

 203#
 204# Define OLD_ICONV if your library has an old iconv(), where the second
 205# (input buffer pointer) parameter is declared with type (const char **).
 206#
 207# Define NO_DEFLATE_BOUND if your zlib does not have deflateBound.
 208#
 209# Define NO_R_TO_GCC_LINKER if your gcc does not like "-R/path/lib"
 210# that tells runtime paths to dynamic libraries;
 211# "-Wl,-rpath=/path/lib" is used instead.
 212#
 213# Define NO_NORETURN if using buggy versions of gcc 4.6+ and profile feedback,
 214# as the compiler can crash (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49299)
 215#
 216# Define USE_NSEC below if you want git to care about sub-second file mtimes
 217# and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
 218# it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
 219# randomly break unless your underlying filesystem supports those sub-second
 220# times (my ext3 doesn't).
 221#
 222# Define USE_ST_TIMESPEC if your "struct stat" uses "st_ctimespec" instead of
 223# "st_ctim"
 224#
 225# Define NO_NSEC if your "struct stat" does not have "st_ctim.tv_nsec"
 226# available.  This automatically turns USE_NSEC off.
 227#
 228# Define USE_STDEV below if you want git to care about the underlying device
 229# change being considered an inode change from the update-index perspective.
 230#
 231# Define NO_ST_BLOCKS_IN_STRUCT_STAT if your platform does not have st_blocks
 232# field that counts the on-disk footprint in 512-byte blocks.
 233#
 234# Define DOCBOOK_XSL_172 if you want to format man pages with DocBook XSL v1.72
 235# (not v1.73 or v1.71).
 236#
 237# Define ASCIIDOC_ROFF if your DocBook XSL does not escape raw roff directives
 238# (versions 1.68.1 through v1.72).
 239#
 240# Define GNU_ROFF if your target system uses GNU groff.  This forces
 241# apostrophes to be ASCII so that cut&pasting examples to the shell
 242# will work.
 243#
 244# Define NO_PERL_MAKEMAKER if you cannot use Makefiles generated by perl's
 245# MakeMaker (e.g. using ActiveState under Cygwin).
 246#
 247# Define NO_PERL if you do not want Perl scripts or libraries at all.
 248#
 249# Define NO_PYTHON if you do not want Python scripts or libraries at all.

 254# used to optimize git-gui for your system.  Only used if NO_TCLTK
 255# is not set.  Defaults to the bare 'tclsh'.
 256#
 257# The TCLTK_PATH variable governs the location of the Tcl/Tk interpreter.
 258# If not set it defaults to the bare 'wish'. If it is set to the empty
 259# string then NO_TCLTK will be forced (this is used by configure script).
 260#
 261# Define INTERNAL_QSORT to use Git's implementation of qsort(), which
 262# is a simplified version of the merge sort used in glibc. This is
 263# recommended if Git triggers O(n^2) behavior in your platform's qsort().
 264#
 265# Define UNRELIABLE_FSTAT if your system's fstat does not return the same
 266# information on a not yet closed file that lstat would return for the same
 267# file after it was closed.
 268#
 269# Define OBJECT_CREATION_USES_RENAMES if your operating systems has problems
 270# when hardlinking a file to another name and unlinking the original file right
 271# away (some NTFS drivers seem to zero the contents in that scenario).
 272#
 273# Define NO_CROSS_DIRECTORY_HARDLINKS if you plan to distribute the installed
 274# programs as a tar, where bin/ and libexec/ might be on different file systems.
 275#
 276# Define NO_INSTALL_HARDLINKS if you prefer to use either symbolic links or
 277# copies to install built-in git commands e.g. git-cat-file.
 278#
 279# Define USE_NED_ALLOCATOR if you want to replace the platforms default
 280# memory allocators with the nedmalloc allocator written by Niall Douglas.
 281#
 282# Define NO_REGEX if you have no or inferior regex support in your C library.
 283#
 284# Define HAVE_DEV_TTY if your system can open /dev/tty to interact with the
 285# user.
 286#
 287# Define GETTEXT_POISON if you are debugging the choice of strings marked
 288# for translation.  In a GETTEXT_POISON build, you can turn all strings marked
 289# for translation into gibberish by setting the GIT_GETTEXT_POISON variable
 290# (to any value) in your environment.
 291#
 292# Define JSMIN to point to JavaScript minifier that functions as
 293# a filter to have gitweb.js minified.
 294#
 295# Define CSSMIN to point to a CSS minifier in order to generate a minified
 296# version of gitweb.css
 297#
 298# Define DEFAULT_PAGER to a sensible pager command (defaults to "less") if
 299# you want to use something different.  The value will be interpreted by the
 300# shell at runtime when it is used.
 301#
 302# Define DEFAULT_EDITOR to a sensible editor command (defaults to "vi") if you
 303# want to use something different.  The value will be interpreted by the shell
 304# if necessary when it is used.  Examples:
 305#
 306#   DEFAULT_EDITOR='~/bin/vi',
 307#   DEFAULT_EDITOR='$GIT_FALLBACK_EDITOR',
 308#   DEFAULT_EDITOR='"C:\Program Files\Vim\gvim.exe" --nofork'
 309#
 310# Define COMPUTE_HEADER_DEPENDENCIES to "yes" if you want dependencies on
 311# header files to be automatically computed, to avoid rebuilding objects when
 312# an unrelated header file changes.  Define it to "no" to use the hard-coded
 313# dependency rules.  The default is "auto", which means to use computed header
 314# dependencies if your compiler is detected to support it.
 315#
 316# Define CHECK_HEADER_DEPENDENCIES to check for problems in the hard-coded
 317# dependency rules.
 318#
 319# Define NATIVE_CRLF if your platform uses CRLF for line endings.
 320#
 321# Define XDL_FAST_HASH to use an alternative line-hashing method in
 322# the diff algorithm.  It gives a nice speedup if your processor has
 323# fast unaligned word loads.  Does NOT work on big-endian systems!
 324# Enabled by default on x86_64.
 325#
 326# Define GIT_USER_AGENT if you want to change how git identifies itself during
 327# network interactions.  The default is "git/$(GIT_VERSION)".
 328#
 329# Define DEFAULT_HELP_FORMAT to "man", "info" or "html"
 330# (defaults to "man") if you want to have a different default when
 331# "git help" is called without a parameter specifying the format.

1596### Target-specific flags and dependencies
1597
1598# The generic compilation pattern rule and automatically
1599# computed header dependencies (falling back to a dependency on
1600# LIB_H) are enough to describe how most targets should be built,
1601# but some targets are special enough to need something a little
1602# different.
1603#
1604# - When a source file "foo.c" #includes a generated header file,
1605#   we need to list that dependency for the "foo.o" target.
1606#
1607#   We also list it from other targets that are built from foo.c
1608#   like "foo.sp" and "foo.s", even though that is easy to forget
1609#   to do because the generated header is already present around
1610#   after a regular build attempt.
1611#
1612# - Some code depends on configuration kept in makefile
1613#   variables. The target-specific variable EXTRA_CPPFLAGS can
1614#   be used to convey that information to the C preprocessor
1615#   using -D options.
1616#
1617#   The "foo.o" target should have a corresponding dependency on
1618#   a file that changes when the value of the makefile variable
1619#   changes.  For example, targets making use of the
1620#   $(GIT_VERSION) variable depend on GIT-VERSION-FILE.
1621#
1622#   Technically the ".sp" and ".s" targets do not need this
1623#   dependency because they are force-built, but they get the
1624#   same dependency for consistency. This way, you do not have to
1625#   know how each target is implemented. And it means the
1626#   dependencies here will not need to change if the force-build
1627#   details change some day.
