Makefileon commit Merge branch 'rs/win32-syslog-leakfix' (b8feb6e)
   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 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# This also implies BLK_SHA1.
  27#
  28# Define USE_LIBPCRE if you have and want to use libpcre. Various
  29# commands such as log and grep offer runtime options to use
  30# Perl-compatible regular expressions instead of standard or extended
  31# POSIX regular expressions.
  32#
  33# Currently USE_LIBPCRE is a synonym for USE_LIBPCRE1, define
  34# USE_LIBPCRE2 instead if you'd like to use version 2 of the PCRE
  35# library. The USE_LIBPCRE flag will likely be changed to mean v2 by
  36# default in future releases.
  37#
  38# When using USE_LIBPCRE1, define NO_LIBPCRE1_JIT if the PCRE v1
  39# library is compiled without --enable-jit. We will auto-detect
  40# whether the version of the PCRE v1 library in use has JIT support at
  41# all, but we unfortunately can't auto-detect whether JIT support
  42# hasn't been compiled in in an otherwise JIT-supporting version. If
  43# you have link-time errors about a missing `pcre_jit_exec` define
  44# this, or recompile PCRE v1 with --enable-jit.
  45#
  46# Define LIBPCREDIR=/foo/bar if your PCRE header and library files are
  47# in /foo/bar/include and /foo/bar/lib directories. Which version of
  48# PCRE this points to determined by the USE_LIBPCRE1 and USE_LIBPCRE2
  49# variables.
  50#
  51# Define HAVE_ALLOCA_H if you have working alloca(3) defined in that header.
  52#
  53# Define NO_CURL if you do not have libcurl installed.  git-http-fetch and
  54# git-http-push are not built, and you cannot use http:// and https://
  55# transports (neither smart nor dumb).
  56#
  57# Define CURLDIR=/foo/bar if your curl header and library files are in
  58# /foo/bar/include and /foo/bar/lib directories.
  59#
  60# Define CURL_CONFIG to curl's configuration program that prints information
  61# about the library (e.g., its version number).  The default is 'curl-config'.
  62#
  63# Define NO_EXPAT if you do not have expat installed.  git-http-push is
  64# not built, and you cannot push using http:// and https:// transports (dumb).
  65#
  66# Define EXPATDIR=/foo/bar if your expat header and library files are in
  67# /foo/bar/include and /foo/bar/lib directories.
  68#
  69# Define EXPAT_NEEDS_XMLPARSE_H if you have an old version of expat (e.g.,
  70# 1.1 or 1.2) that provides xmlparse.h instead of expat.h.
  71#
  72# Define NO_GETTEXT if you don't want Git output to be translated.
  73# A translated Git requires GNU libintl or another gettext implementation,
  74# plus libintl-perl at runtime.
  75#
  76# Define USE_GETTEXT_SCHEME and set it to 'fallthrough', if you don't trust
  77# the installed gettext translation of the shell scripts output.
  78#
  79# Define HAVE_LIBCHARSET_H if you haven't set NO_GETTEXT and you can't
  80# trust the langinfo.h's nl_langinfo(CODESET) function to return the
  81# current character set. GNU and Solaris have a nl_langinfo(CODESET),
  82# FreeBSD can use either, but MinGW and some others need to use
  83# libcharset.h's locale_charset() instead.
  84#
  85# Define CHARSET_LIB to the library you need to link with in order to
  86# use locale_charset() function.  On some platforms this needs to set to
  87# -lcharset, on others to -liconv .
  88#
  89# Define LIBC_CONTAINS_LIBINTL if your gettext implementation doesn't
  90# need -lintl when linking.
  91#
  92# Define NO_MSGFMT_EXTENDED_OPTIONS if your implementation of msgfmt
  93# doesn't support GNU extensions like --check and --statistics
  94#
  95# Define HAVE_PATHS_H if you have paths.h and want to use the default PATH
  96# it specifies.
  97#
  98# Define NO_D_TYPE_IN_DIRENT if your platform defines DT_UNKNOWN but lacks
  99# d_type in struct dirent (Cygwin 1.5, fixed in Cygwin 1.7).
 100#
 101# Define HAVE_STRINGS_H if you have strings.h and need it for strcasecmp.
 102#
 103# Define NO_STRCASESTR if you don't have strcasestr.
 104#
 105# Define NO_MEMMEM if you don't have memmem.
 106#
 107# Define NO_GETPAGESIZE if you don't have getpagesize.
 108#
 109# Define NO_STRLCPY if you don't have strlcpy.
 110#
 111# Define NO_STRTOUMAX if you don't have both strtoimax and strtoumax in the
 112# C library. If your compiler also does not support long long or does not have
 113# strtoull, define NO_STRTOULL.
 114#
 115# Define NO_SETENV if you don't have setenv in the C library.
 116#
 117# Define NO_UNSETENV if you don't have unsetenv in the C library.
 118#
 119# Define NO_MKDTEMP if you don't have mkdtemp in the C library.
 120#
 121# Define MKDIR_WO_TRAILING_SLASH if your mkdir() can't deal with trailing slash.
 122#
 123# Define NO_GECOS_IN_PWENT if you don't have pw_gecos in struct passwd
 124# in the C library.
 125#
 126# Define NO_LIBGEN_H if you don't have libgen.h.
 127#
 128# Define NEEDS_LIBGEN if your libgen needs -lgen when linking
 129#
 130# Define NO_SYS_SELECT_H if you don't have sys/select.h.
 131#
 132# Define NO_SYMLINK_HEAD if you never want .git/HEAD to be a symbolic link.
 133# Enable it on Windows.  By default, symrefs are still used.
 134#
 135# Define NO_SVN_TESTS if you want to skip time-consuming SVN interoperability
 136# tests.  These tests take up a significant amount of the total test time
 137# but are not needed unless you plan to talk to SVN repos.
 138#
 139# Define NO_FINK if you are building on Darwin/Mac OS X, have Fink
 140# installed in /sw, but don't want GIT to link against any libraries
 141# installed there.  If defined you may specify your own (or Fink's)
 142# include directories and library directories by defining CFLAGS
 143# and LDFLAGS appropriately.
 144#
 145# Define NO_DARWIN_PORTS if you are building on Darwin/Mac OS X,
 146# have DarwinPorts installed in /opt/local, but don't want GIT to
 147# link against any libraries installed there.  If defined you may
 148# specify your own (or DarwinPort's) include directories and
 149# library directories by defining CFLAGS and LDFLAGS appropriately.
 150#
 151# Define NO_APPLE_COMMON_CRYPTO if you are building on Darwin/Mac OS X
 152# and do not want to use Apple's CommonCrypto library.  This allows you
 153# to provide your own OpenSSL library, for example from MacPorts.
 154#
 155# Define BLK_SHA1 environment variable to make use of the bundled
 156# optimized C SHA1 routine.
 157#
 158# Define PPC_SHA1 environment variable when running make to make use of
 159# a bundled SHA1 routine optimized for PowerPC.
 160#
 161# Define DC_SHA1 to unconditionally enable the collision-detecting sha1
 162# algorithm. This is slower, but may detect attempted collision attacks.
 163# Takes priority over other *_SHA1 knobs.
 164#
 165# Define DC_SHA1_SUBMODULE in addition to DC_SHA1 to use the
 166# sha1collisiondetection shipped as a submodule instead of the
 167# non-submodule copy in sha1dc/. This is an experimental option used
 168# by the git project to migrate to using sha1collisiondetection as a
 169# submodule.
 170#
 171# Define OPENSSL_SHA1 environment variable when running make to link
 172# with the SHA1 routine from openssl library.
 173#
 174# Define SHA1_MAX_BLOCK_SIZE to limit the amount of data that will be hashed
 175# in one call to the platform's SHA1_Update(). e.g. APPLE_COMMON_CRYPTO
 176# wants 'SHA1_MAX_BLOCK_SIZE=1024L*1024L*1024L' defined.
 177#
 178# Define NEEDS_CRYPTO_WITH_SSL if you need -lcrypto when using -lssl (Darwin).
 179#
 180# Define NEEDS_SSL_WITH_CRYPTO if you need -lssl when using -lcrypto (Darwin).
 181#
 182# Define NEEDS_SSL_WITH_CURL if you need -lssl with -lcurl (Minix).
 183#
 184# Define NEEDS_IDN_WITH_CURL if you need -lidn when using -lcurl (Minix).
 185#
 186# Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
 187#
 188# Define NEEDS_LIBINTL_BEFORE_LIBICONV if you need libintl before libiconv.
 189#
 190# Define NO_INTPTR_T if you don't have intptr_t or uintptr_t.
 191#
 192# Define NO_UINTMAX_T if you don't have uintmax_t.
 193#
 194# Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
 195# Patrick Mauritz).
 196#
 197# Define NEEDS_RESOLV if linking with -lnsl and/or -lsocket is not enough.
 198# Notably on Solaris hstrerror resides in libresolv and on Solaris 7
 199# inet_ntop and inet_pton additionally reside there.
 200#
 201# Define NO_MMAP if you want to avoid mmap.
 202#
 203# Define NO_SYS_POLL_H if you don't have sys/poll.h.
 204#
 205# Define NO_POLL if you do not have or don't want to use poll().
 206# This also implies NO_SYS_POLL_H.
 207#
 208# Define NEEDS_SYS_PARAM_H if you need to include sys/param.h to compile,
 209# *PLEASE* REPORT to git@vger.kernel.org if your platform needs this;
 210# we want to know more about the issue.
 211#
 212# Define NO_PTHREADS if you do not have or do not want to use Pthreads.
 213#
 214# Define NO_PREAD if you have a problem with pread() system call (e.g.
 215# cygwin1.dll before v1.5.22).
 216#
 217# Define NO_SETITIMER if you don't have setitimer()
 218#
 219# Define NO_STRUCT_ITIMERVAL if you don't have struct itimerval
 220# This also implies NO_SETITIMER
 221#
 222# Define NO_FAST_WORKING_DIRECTORY if accessing objects in pack files is
 223# generally faster on your platform than accessing the working directory.
 224#
 225# Define NO_TRUSTABLE_FILEMODE if your filesystem may claim to support
 226# the executable mode bit, but doesn't really do so.
 227#
 228# Define NEEDS_MODE_TRANSLATION if your OS strays from the typical file type
 229# bits in mode values (e.g. z/OS defines I_SFMT to 0xFF000000 as opposed to the
 230# usual 0xF000).
 231#
 232# Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
 233#
 234# Define NO_UNIX_SOCKETS if your system does not offer unix sockets.
 235#
 236# Define NO_SOCKADDR_STORAGE if your platform does not have struct
 237# sockaddr_storage.
 238#
 239# Define NO_ICONV if your libc does not properly support iconv.
 240#
 241# Define OLD_ICONV if your library has an old iconv(), where the second
 242# (input buffer pointer) parameter is declared with type (const char **).
 243#
 244# Define NO_DEFLATE_BOUND if your zlib does not have deflateBound.
 245#
 246# Define NO_R_TO_GCC_LINKER if your gcc does not like "-R/path/lib"
 247# that tells runtime paths to dynamic libraries;
 248# "-Wl,-rpath=/path/lib" is used instead.
 249#
 250# Define NO_NORETURN if using buggy versions of gcc 4.6+ and profile feedback,
 251# as the compiler can crash (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49299)
 252#
 253# Define USE_NSEC below if you want git to care about sub-second file mtimes
 254# and ctimes. Note that you need recent glibc (at least 2.2.4) for this. On
 255# Linux, kernel 2.6.11 or newer is required for reliable sub-second file times
 256# on file systems with exactly 1 ns or 1 s resolution. If you intend to use Git
 257# on other file systems (e.g. CEPH, CIFS, NTFS, UDF), don't enable USE_NSEC. See
 258# Documentation/technical/racy-git.txt for details.
 259#
 260# Define USE_ST_TIMESPEC if your "struct stat" uses "st_ctimespec" instead of
 261# "st_ctim"
 262#
 263# Define NO_NSEC if your "struct stat" does not have "st_ctim.tv_nsec"
 264# available.  This automatically turns USE_NSEC off.
 265#
 266# Define USE_STDEV below if you want git to care about the underlying device
 267# change being considered an inode change from the update-index perspective.
 268#
 269# Define NO_ST_BLOCKS_IN_STRUCT_STAT if your platform does not have st_blocks
 270# field that counts the on-disk footprint in 512-byte blocks.
 271#
 272# Define DOCBOOK_XSL_172 if you want to format man pages with DocBook XSL v1.72
 273# (not v1.73 or v1.71).
 274#
 275# Define ASCIIDOC_ROFF if your DocBook XSL does not escape raw roff directives
 276# (versions 1.68.1 through v1.72).
 277#
 278# Define GNU_ROFF if your target system uses GNU groff.  This forces
 279# apostrophes to be ASCII so that cut&pasting examples to the shell
 280# will work.
 281#
 282# Define USE_ASCIIDOCTOR to use Asciidoctor instead of AsciiDoc to build the
 283# documentation.
 284#
 285# Define ASCIIDOCTOR_EXTENSIONS_LAB to point to the location of the Asciidoctor
 286# Extensions Lab if you have it available.
 287#
 288# Define PERL_PATH to the path of your Perl binary (usually /usr/bin/perl).
 289#
 290# Define NO_PERL_MAKEMAKER if you cannot use Makefiles generated by perl's
 291# MakeMaker (e.g. using ActiveState under Cygwin).
 292#
 293# Define NO_PERL if you do not want Perl scripts or libraries at all.
 294#
 295# Define PYTHON_PATH to the path of your Python binary (often /usr/bin/python
 296# but /usr/bin/python2.7 on some platforms).
 297#
 298# Define NO_PYTHON if you do not want Python scripts or libraries at all.
 299#
 300# Define NO_TCLTK if you do not want Tcl/Tk GUI.
 301#
 302# Define SANE_TEXT_GREP to "-a" if you use recent versions of GNU grep
 303# and egrep that are pickier when their input contains non-ASCII data.
 304#
 305# The TCL_PATH variable governs the location of the Tcl interpreter
 306# used to optimize git-gui for your system.  Only used if NO_TCLTK
 307# is not set.  Defaults to the bare 'tclsh'.
 308#
 309# The TCLTK_PATH variable governs the location of the Tcl/Tk interpreter.
 310# If not set it defaults to the bare 'wish'. If it is set to the empty
 311# string then NO_TCLTK will be forced (this is used by configure script).
 312#
 313# Define INTERNAL_QSORT to use Git's implementation of qsort(), which
 314# is a simplified version of the merge sort used in glibc. This is
 315# recommended if Git triggers O(n^2) behavior in your platform's qsort().
 316#
 317# Define HAVE_ISO_QSORT_S if your platform provides a qsort_s() that's
 318# compatible with the one described in C11 Annex K.
 319#
 320# Define UNRELIABLE_FSTAT if your system's fstat does not return the same
 321# information on a not yet closed file that lstat would return for the same
 322# file after it was closed.
 323#
 324# Define OBJECT_CREATION_USES_RENAMES if your operating systems has problems
 325# when hardlinking a file to another name and unlinking the original file right
 326# away (some NTFS drivers seem to zero the contents in that scenario).
 327#
 328# Define NO_CROSS_DIRECTORY_HARDLINKS if you plan to distribute the installed
 329# programs as a tar, where bin/ and libexec/ might be on different file systems.
 330#
 331# Define NO_INSTALL_HARDLINKS if you prefer to use either symbolic links or
 332# copies to install built-in git commands e.g. git-cat-file.
 333#
 334# Define USE_NED_ALLOCATOR if you want to replace the platforms default
 335# memory allocators with the nedmalloc allocator written by Niall Douglas.
 336#
 337# Define OVERRIDE_STRDUP to override the libc version of strdup(3).
 338# This is necessary when using a custom allocator in order to avoid
 339# crashes due to allocation and free working on different 'heaps'.
 340# It's defined automatically if USE_NED_ALLOCATOR is set.
 341#
 342# Define NO_REGEX if your C library lacks regex support with REG_STARTEND
 343# feature.
 344#
 345# Define HAVE_DEV_TTY if your system can open /dev/tty to interact with the
 346# user.
 347#
 348# Define GETTEXT_POISON if you are debugging the choice of strings marked
 349# for translation.  In a GETTEXT_POISON build, you can turn all strings marked
 350# for translation into gibberish by setting the GIT_GETTEXT_POISON variable
 351# (to any value) in your environment.
 352#
 353# Define JSMIN to point to JavaScript minifier that functions as
 354# a filter to have gitweb.js minified.
 355#
 356# Define CSSMIN to point to a CSS minifier in order to generate a minified
 357# version of gitweb.css
 358#
 359# Define DEFAULT_PAGER to a sensible pager command (defaults to "less") if
 360# you want to use something different.  The value will be interpreted by the
 361# shell at runtime when it is used.
 362#
 363# Define DEFAULT_EDITOR to a sensible editor command (defaults to "vi") if you
 364# want to use something different.  The value will be interpreted by the shell
 365# if necessary when it is used.  Examples:
 366#
 367#   DEFAULT_EDITOR='~/bin/vi',
 368#   DEFAULT_EDITOR='$GIT_FALLBACK_EDITOR',
 369#   DEFAULT_EDITOR='"C:\Program Files\Vim\gvim.exe" --nofork'
 370#
 371# Define COMPUTE_HEADER_DEPENDENCIES to "yes" if you want dependencies on
 372# header files to be automatically computed, to avoid rebuilding objects when
 373# an unrelated header file changes.  Define it to "no" to use the hard-coded
 374# dependency rules.  The default is "auto", which means to use computed header
 375# dependencies if your compiler is detected to support it.
 376#
 377# Define NATIVE_CRLF if your platform uses CRLF for line endings.
 378#
 379# Define GIT_USER_AGENT if you want to change how git identifies itself during
 380# network interactions.  The default is "git/$(GIT_VERSION)".
 381#
 382# Define DEFAULT_HELP_FORMAT to "man", "info" or "html"
 383# (defaults to "man") if you want to have a different default when
 384# "git help" is called without a parameter specifying the format.
 385#
 386# Define TEST_GIT_INDEX_VERSION to 2, 3 or 4 to run the test suite
 387# with a different indexfile format version.  If it isn't set the index
 388# file format used is index-v[23].
 389#
 390# Define GMTIME_UNRELIABLE_ERRORS if your gmtime() function does not
 391# return NULL when it receives a bogus time_t.
 392#
 393# Define HAVE_CLOCK_GETTIME if your platform has clock_gettime.
 394#
 395# Define HAVE_CLOCK_MONOTONIC if your platform has CLOCK_MONOTONIC.
 396#
 397# Define NEEDS_LIBRT if your platform requires linking with librt (glibc version
 398# before 2.17) for clock_gettime and CLOCK_MONOTONIC.
 399#
 400# Define USE_PARENS_AROUND_GETTEXT_N to "yes" if your compiler happily
 401# compiles the following initialization:
 402#
 403#   static const char s[] = ("FOO");
 404#
 405# and define it to "no" if you need to remove the parentheses () around the
 406# constant.  The default is "auto", which means to use parentheses if your
 407# compiler is detected to support it.
 408#
 409# Define HAVE_BSD_SYSCTL if your platform has a BSD-compatible sysctl function.
 410#
 411# Define HAVE_GETDELIM if your system has the getdelim() function.
 412#
 413# Define PAGER_ENV to a SP separated VAR=VAL pairs to define
 414# default environment variables to be passed when a pager is spawned, e.g.
 415#
 416#    PAGER_ENV = LESS=FRX LV=-c
 417#
 418# to say "export LESS=FRX (and LV=-c) if the environment variable
 419# LESS (and LV) is not set, respectively".

1813### Target-specific flags and dependencies
1814
1815# The generic compilation pattern rule and automatically
1816# computed header dependencies (falling back to a dependency on
1817# LIB_H) are enough to describe how most targets should be built,
1818# but some targets are special enough to need something a little
1819# different.
1820#
1821# - When a source file "foo.c" #includes a generated header file,
1822#   we need to list that dependency for the "foo.o" target.
1823#
1824#   We also list it from other targets that are built from foo.c
1825#   like "foo.sp" and "foo.s", even though that is easy to forget
1826#   to do because the generated header is already present around
1827#   after a regular build attempt.
1828#
1829# - Some code depends on configuration kept in makefile
1830#   variables. The target-specific variable EXTRA_CPPFLAGS can
1831#   be used to convey that information to the C preprocessor
1832#   using -D options.
1833#
1834#   The "foo.o" target should have a corresponding dependency on
1835#   a file that changes when the value of the makefile variable
1836#   changes.  For example, targets making use of the
1837#   $(GIT_VERSION) variable depend on GIT-VERSION-FILE.
1838#
1839#   Technically the ".sp" and ".s" targets do not need this
1840#   dependency because they are force-built, but they get the
1841#   same dependency for consistency. This way, you do not have to
1842#   know how each target is implemented. And it means the
1843#   dependencies here will not need to change if the force-build
1844#   details change some day.
