Makefileon commit Makefile: add a DEVOPTS to get all of -Wextra (26d2e4f)
   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#
  27# Define USE_LIBPCRE if you have and want to use libpcre. Various
  28# commands such as log and grep offer runtime options to use
  29# Perl-compatible regular expressions instead of standard or extended
  30# POSIX regular expressions.
  31#
  32# Currently USE_LIBPCRE is a synonym for USE_LIBPCRE1, define
  33# USE_LIBPCRE2 instead if you'd like to use version 2 of the PCRE
  34# library. The USE_LIBPCRE flag will likely be changed to mean v2 by
  35# default in future releases.
  36#
  37# When using USE_LIBPCRE1, define NO_LIBPCRE1_JIT if the PCRE v1
  38# library is compiled without --enable-jit. We will auto-detect
  39# whether the version of the PCRE v1 library in use has JIT support at
  40# all, but we unfortunately can't auto-detect whether JIT support
  41# hasn't been compiled in in an otherwise JIT-supporting version. If
  42# you have link-time errors about a missing `pcre_jit_exec` define
  43# this, or recompile PCRE v1 with --enable-jit.
  44#
  45# Define LIBPCREDIR=/foo/bar if your PCRE header and library files are
  46# in /foo/bar/include and /foo/bar/lib directories. Which version of
  47# PCRE this points to determined by the USE_LIBPCRE1 and USE_LIBPCRE2
  48# variables.
  49#
  50# Define HAVE_ALLOCA_H if you have working alloca(3) defined in that header.
  51#
  52# Define NO_CURL if you do not have libcurl installed.  git-http-fetch and
  53# git-http-push are not built, and you cannot use http:// and https://
  54# transports (neither smart nor dumb).
  55#
  56# Define CURLDIR=/foo/bar if your curl header and library files are in
  57# /foo/bar/include and /foo/bar/lib directories.
  58#
  59# Define CURL_CONFIG to curl's configuration program that prints information
  60# about the library (e.g., its version number).  The default is 'curl-config'.
  61#
  62# Define NO_EXPAT if you do not have expat installed.  git-http-push is
  63# not built, and you cannot push using http:// and https:// transports (dumb).
  64#
  65# Define EXPATDIR=/foo/bar if your expat header and library files are in
  66# /foo/bar/include and /foo/bar/lib directories.
  67#
  68# Define EXPAT_NEEDS_XMLPARSE_H if you have an old version of expat (e.g.,
  69# 1.1 or 1.2) that provides xmlparse.h instead of expat.h.
  70#
  71# Define NO_GETTEXT if you don't want Git output to be translated.
  72# A translated Git requires GNU libintl or another gettext implementation,
  73# plus libintl-perl at runtime.
  74#
  75# Define USE_GETTEXT_SCHEME and set it to 'fallthrough', if you don't trust
  76# the installed gettext translation of the shell scripts output.
  77#
  78# Define HAVE_LIBCHARSET_H if you haven't set NO_GETTEXT and you can't
  79# trust the langinfo.h's nl_langinfo(CODESET) function to return the
  80# current character set. GNU and Solaris have a nl_langinfo(CODESET),
  81# FreeBSD can use either, but MinGW and some others need to use
  82# libcharset.h's locale_charset() instead.
  83#
  84# Define CHARSET_LIB to the library you need to link with in order to
  85# use locale_charset() function.  On some platforms this needs to set to
  86# -lcharset, on others to -liconv .
  87#
  88# Define LIBC_CONTAINS_LIBINTL if your gettext implementation doesn't
  89# need -lintl when linking.
  90#
  91# Define NO_MSGFMT_EXTENDED_OPTIONS if your implementation of msgfmt
  92# doesn't support GNU extensions like --check and --statistics
  93#
  94# Define HAVE_PATHS_H if you have paths.h and want to use the default PATH
  95# it specifies.
  96#
  97# Define NO_D_TYPE_IN_DIRENT if your platform defines DT_UNKNOWN but lacks
  98# d_type in struct dirent (Cygwin 1.5, fixed in Cygwin 1.7).
  99#
 100# Define HAVE_STRINGS_H if you have strings.h and need it for strcasecmp.
 101#
 102# Define NO_STRCASESTR if you don't have strcasestr.
 103#
 104# Define NO_MEMMEM if you don't have memmem.
 105#
 106# Define NO_GETPAGESIZE if you don't have getpagesize.
 107#
 108# Define NO_STRLCPY if you don't have strlcpy.
 109#
 110# Define NO_STRTOUMAX if you don't have both strtoimax and strtoumax in the
 111# C library. If your compiler also does not support long long or does not have
 112# strtoull, define NO_STRTOULL.
 113#
 114# Define NO_SETENV if you don't have setenv in the C library.
 115#
 116# Define NO_UNSETENV if you don't have unsetenv in the C library.
 117#
 118# Define NO_MKDTEMP if you don't have mkdtemp in the C library.
 119#
 120# Define MKDIR_WO_TRAILING_SLASH if your mkdir() can't deal with trailing slash.
 121#
 122# Define NO_GECOS_IN_PWENT if you don't have pw_gecos in struct passwd
 123# in the C library.
 124#
 125# Define NO_LIBGEN_H if you don't have libgen.h.
 126#
 127# Define NEEDS_LIBGEN if your libgen needs -lgen when linking
 128#
 129# Define NO_SYS_SELECT_H if you don't have sys/select.h.
 130#
 131# Define NO_SYMLINK_HEAD if you never want .git/HEAD to be a symbolic link.
 132# Enable it on Windows.  By default, symrefs are still used.
 133#
 134# Define NO_SVN_TESTS if you want to skip time-consuming SVN interoperability
 135# tests.  These tests take up a significant amount of the total test time
 136# but are not needed unless you plan to talk to SVN repos.
 137#
 138# Define NO_FINK if you are building on Darwin/Mac OS X, have Fink
 139# installed in /sw, but don't want GIT to link against any libraries
 140# installed there.  If defined you may specify your own (or Fink's)
 141# include directories and library directories by defining CFLAGS
 142# and LDFLAGS appropriately.
 143#
 144# Define NO_DARWIN_PORTS if you are building on Darwin/Mac OS X,
 145# have DarwinPorts installed in /opt/local, but don't want GIT to
 146# link against any libraries installed there.  If defined you may
 147# specify your own (or DarwinPort's) include directories and
 148# library directories by defining CFLAGS and LDFLAGS appropriately.
 149#
 150# Define NO_APPLE_COMMON_CRYPTO if you are building on Darwin/Mac OS X
 151# and do not want to use Apple's CommonCrypto library.  This allows you
 152# to provide your own OpenSSL library, for example from MacPorts.
 153#
 154# Define BLK_SHA1 environment variable to make use of the bundled
 155# optimized C SHA1 routine.
 156#
 157# Define PPC_SHA1 environment variable when running make to make use of
 158# a bundled SHA1 routine optimized for PowerPC.
 159#
 160# Define DC_SHA1 to unconditionally enable the collision-detecting sha1
 161# algorithm. This is slower, but may detect attempted collision attacks.
 162# Takes priority over other *_SHA1 knobs.
 163#
 164# Define DC_SHA1_EXTERNAL in addition to DC_SHA1 if you want to build / link
 165# git with the external SHA1 collision-detect library.
 166# Without this option, i.e. the default behavior is to build git with its
 167# own built-in code (or submodule).
 168#
 169# Define DC_SHA1_SUBMODULE in addition to DC_SHA1 to use the
 170# sha1collisiondetection shipped as a submodule instead of the
 171# non-submodule copy in sha1dc/. This is an experimental option used
 172# by the git project to migrate to using sha1collisiondetection as a
 173# submodule.
 174#
 175# Define OPENSSL_SHA1 environment variable when running make to link
 176# with the SHA1 routine from openssl library.
 177#
 178# Define SHA1_MAX_BLOCK_SIZE to limit the amount of data that will be hashed
 179# in one call to the platform's SHA1_Update(). e.g. APPLE_COMMON_CRYPTO
 180# wants 'SHA1_MAX_BLOCK_SIZE=1024L*1024L*1024L' defined.
 181#
 182# Define NEEDS_CRYPTO_WITH_SSL if you need -lcrypto when using -lssl (Darwin).
 183#
 184# Define NEEDS_SSL_WITH_CRYPTO if you need -lssl when using -lcrypto (Darwin).
 185#
 186# Define NEEDS_SSL_WITH_CURL if you need -lssl with -lcurl (Minix).
 187#
 188# Define NEEDS_IDN_WITH_CURL if you need -lidn when using -lcurl (Minix).
 189#
 190# Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
 191#
 192# Define NEEDS_LIBINTL_BEFORE_LIBICONV if you need libintl before libiconv.
 193#
 194# Define NO_INTPTR_T if you don't have intptr_t or uintptr_t.
 195#
 196# Define NO_UINTMAX_T if you don't have uintmax_t.
 197#
 198# Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
 199# Patrick Mauritz).
 200#
 201# Define NEEDS_RESOLV if linking with -lnsl and/or -lsocket is not enough.
 202# Notably on Solaris hstrerror resides in libresolv and on Solaris 7
 203# inet_ntop and inet_pton additionally reside there.
 204#
 205# Define NO_MMAP if you want to avoid mmap.
 206#
 207# Define MMAP_PREVENTS_DELETE if a file that is currently mmapped cannot be
 208# deleted or cannot be replaced using rename().
 209#
 210# Define NO_SYS_POLL_H if you don't have sys/poll.h.
 211#
 212# Define NO_POLL if you do not have or don't want to use poll().
 213# This also implies NO_SYS_POLL_H.
 214#
 215# Define NEEDS_SYS_PARAM_H if you need to include sys/param.h to compile,
 216# *PLEASE* REPORT to git@vger.kernel.org if your platform needs this;
 217# we want to know more about the issue.
 218#
 219# Define NO_PTHREADS if you do not have or do not want to use Pthreads.
 220#
 221# Define NO_PREAD if you have a problem with pread() system call (e.g.
 222# cygwin1.dll before v1.5.22).
 223#
 224# Define NO_SETITIMER if you don't have setitimer()
 225#
 226# Define NO_STRUCT_ITIMERVAL if you don't have struct itimerval
 227# This also implies NO_SETITIMER
 228#
 229# Define NO_FAST_WORKING_DIRECTORY if accessing objects in pack files is
 230# generally faster on your platform than accessing the working directory.
 231#
 232# Define NO_TRUSTABLE_FILEMODE if your filesystem may claim to support
 233# the executable mode bit, but doesn't really do so.
 234#
 235# Define NEEDS_MODE_TRANSLATION if your OS strays from the typical file type
 236# bits in mode values (e.g. z/OS defines I_SFMT to 0xFF000000 as opposed to the
 237# usual 0xF000).
 238#
 239# Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
 240#
 241# Define NO_UNIX_SOCKETS if your system does not offer unix sockets.
 242#
 243# Define NO_SOCKADDR_STORAGE if your platform does not have struct
 244# sockaddr_storage.
 245#
 246# Define NO_ICONV if your libc does not properly support iconv.
 247#
 248# Define OLD_ICONV if your library has an old iconv(), where the second
 249# (input buffer pointer) parameter is declared with type (const char **).
 250#
 251# Define NO_DEFLATE_BOUND if your zlib does not have deflateBound.
 252#
 253# Define NO_R_TO_GCC_LINKER if your gcc does not like "-R/path/lib"
 254# that tells runtime paths to dynamic libraries;
 255# "-Wl,-rpath=/path/lib" is used instead.
 256#
 257# Define NO_NORETURN if using buggy versions of gcc 4.6+ and profile feedback,
 258# as the compiler can crash (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49299)
 259#
 260# Define USE_NSEC below if you want git to care about sub-second file mtimes
 261# and ctimes. Note that you need recent glibc (at least 2.2.4) for this. On
 262# Linux, kernel 2.6.11 or newer is required for reliable sub-second file times
 263# on file systems with exactly 1 ns or 1 s resolution. If you intend to use Git
 264# on other file systems (e.g. CEPH, CIFS, NTFS, UDF), don't enable USE_NSEC. See
 265# Documentation/technical/racy-git.txt for details.
 266#
 267# Define USE_ST_TIMESPEC if your "struct stat" uses "st_ctimespec" instead of
 268# "st_ctim"
 269#
 270# Define NO_NSEC if your "struct stat" does not have "st_ctim.tv_nsec"
 271# available.  This automatically turns USE_NSEC off.
 272#
 273# Define USE_STDEV below if you want git to care about the underlying device
 274# change being considered an inode change from the update-index perspective.
 275#
 276# Define NO_ST_BLOCKS_IN_STRUCT_STAT if your platform does not have st_blocks
 277# field that counts the on-disk footprint in 512-byte blocks.
 278#
 279# Define DOCBOOK_XSL_172 if you want to format man pages with DocBook XSL v1.72
 280# (not v1.73 or v1.71).
 281#
 282# Define ASCIIDOC_ROFF if your DocBook XSL does not escape raw roff directives
 283# (versions 1.68.1 through v1.72).
 284#
 285# Define GNU_ROFF if your target system uses GNU groff.  This forces
 286# apostrophes to be ASCII so that cut&pasting examples to the shell
 287# will work.
 288#
 289# Define USE_ASCIIDOCTOR to use Asciidoctor instead of AsciiDoc to build the
 290# documentation.
 291#
 292# Define ASCIIDOCTOR_EXTENSIONS_LAB to point to the location of the Asciidoctor
 293# Extensions Lab if you have it available.
 294#
 295# Define PERL_PATH to the path of your Perl binary (usually /usr/bin/perl).
 296#
 297# Define NO_PERL_MAKEMAKER if you cannot use Makefiles generated by perl's
 298# MakeMaker (e.g. using ActiveState under Cygwin).
 299#
 300# Define NO_PERL if you do not want Perl scripts or libraries at all.
 301#
 302# Define PYTHON_PATH to the path of your Python binary (often /usr/bin/python
 303# but /usr/bin/python2.7 on some platforms).
 304#
 305# Define NO_PYTHON if you do not want Python scripts or libraries at all.
 306#
 307# Define NO_TCLTK if you do not want Tcl/Tk GUI.
 308#
 309# Define SANE_TEXT_GREP to "-a" if you use recent versions of GNU grep
 310# and egrep that are pickier when their input contains non-ASCII data.
 311#
 312# The TCL_PATH variable governs the location of the Tcl interpreter
 313# used to optimize git-gui for your system.  Only used if NO_TCLTK
 314# is not set.  Defaults to the bare 'tclsh'.
 315#
 316# The TCLTK_PATH variable governs the location of the Tcl/Tk interpreter.
 317# If not set it defaults to the bare 'wish'. If it is set to the empty
 318# string then NO_TCLTK will be forced (this is used by configure script).
 319#
 320# Define INTERNAL_QSORT to use Git's implementation of qsort(), which
 321# is a simplified version of the merge sort used in glibc. This is
 322# recommended if Git triggers O(n^2) behavior in your platform's qsort().
 323#
 324# Define HAVE_ISO_QSORT_S if your platform provides a qsort_s() that's
 325# compatible with the one described in C11 Annex K.
 326#
 327# Define UNRELIABLE_FSTAT if your system's fstat does not return the same
 328# information on a not yet closed file that lstat would return for the same
 329# file after it was closed.
 330#
 331# Define OBJECT_CREATION_USES_RENAMES if your operating systems has problems
 332# when hardlinking a file to another name and unlinking the original file right
 333# away (some NTFS drivers seem to zero the contents in that scenario).
 334#
 335# Define NO_CROSS_DIRECTORY_HARDLINKS if you plan to distribute the installed
 336# programs as a tar, where bin/ and libexec/ might be on different file systems.
 337#
 338# Define NO_INSTALL_HARDLINKS if you prefer to use either symbolic links or
 339# copies to install built-in git commands e.g. git-cat-file.
 340#
 341# Define USE_NED_ALLOCATOR if you want to replace the platforms default
 342# memory allocators with the nedmalloc allocator written by Niall Douglas.
 343#
 344# Define OVERRIDE_STRDUP to override the libc version of strdup(3).
 345# This is necessary when using a custom allocator in order to avoid
 346# crashes due to allocation and free working on different 'heaps'.
 347# It's defined automatically if USE_NED_ALLOCATOR is set.
 348#
 349# Define NO_REGEX if your C library lacks regex support with REG_STARTEND
 350# feature.
 351#
 352# Define HAVE_DEV_TTY if your system can open /dev/tty to interact with the
 353# user.
 354#
 355# Define GETTEXT_POISON if you are debugging the choice of strings marked
 356# for translation.  In a GETTEXT_POISON build, you can turn all strings marked

 358# (to any value) in your environment.
 359#
 360# Define JSMIN to point to JavaScript minifier that functions as
 361# a filter to have gitweb.js minified.
 362#
 363# Define CSSMIN to point to a CSS minifier in order to generate a minified
 364# version of gitweb.css
 365#
 366# Define DEFAULT_PAGER to a sensible pager command (defaults to "less") if
 367# you want to use something different.  The value will be interpreted by the
 368# shell at runtime when it is used.
 369#
 370# Define DEFAULT_EDITOR to a sensible editor command (defaults to "vi") if you
 371# want to use something different.  The value will be interpreted by the shell
 372# if necessary when it is used.  Examples:
 373#
 374#   DEFAULT_EDITOR='~/bin/vi',
 375#   DEFAULT_EDITOR='$GIT_FALLBACK_EDITOR',
 376#   DEFAULT_EDITOR='"C:\Program Files\Vim\gvim.exe" --nofork'
 377#
 378# Define COMPUTE_HEADER_DEPENDENCIES to "yes" if you want dependencies on
 379# header files to be automatically computed, to avoid rebuilding objects when
 380# an unrelated header file changes.  Define it to "no" to use the hard-coded
 381# dependency rules.  The default is "auto", which means to use computed header
 382# dependencies if your compiler is detected to support it.
 383#
 384# Define NATIVE_CRLF if your platform uses CRLF for line endings.
 385#
 386# Define GIT_USER_AGENT if you want to change how git identifies itself during
 387# network interactions.  The default is "git/$(GIT_VERSION)".
 388#
 389# Define DEFAULT_HELP_FORMAT to "man", "info" or "html"
 390# (defaults to "man") if you want to have a different default when
 391# "git help" is called without a parameter specifying the format.
 392#
 393# Define TEST_GIT_INDEX_VERSION to 2, 3 or 4 to run the test suite
 394# with a different indexfile format version.  If it isn't set the index
 395# file format used is index-v[23].
 396#
 397# Define GMTIME_UNRELIABLE_ERRORS if your gmtime() function does not
 398# return NULL when it receives a bogus time_t.
 399#
 400# Define HAVE_CLOCK_GETTIME if your platform has clock_gettime.
 401#
 402# Define HAVE_CLOCK_MONOTONIC if your platform has CLOCK_MONOTONIC.
 403#
 404# Define NEEDS_LIBRT if your platform requires linking with librt (glibc version
 405# before 2.17) for clock_gettime and CLOCK_MONOTONIC.
 406#
 407# Define USE_PARENS_AROUND_GETTEXT_N to "yes" if your compiler happily
 408# compiles the following initialization:
 409#
 410#   static const char s[] = ("FOO");
 411#
 412# and define it to "no" if you need to remove the parentheses () around the
 413# constant.  The default is "auto", which means to use parentheses if your
 414# compiler is detected to support it.
 415#
 416# Define HAVE_BSD_SYSCTL if your platform has a BSD-compatible sysctl function.
 417#
 418# Define HAVE_GETDELIM if your system has the getdelim() function.
 419#
 420# Define PAGER_ENV to a SP separated VAR=VAL pairs to define
 421# default environment variables to be passed when a pager is spawned, e.g.
 422#
 423#    PAGER_ENV = LESS=FRX LV=-c
 424#
 425# to say "export LESS=FRX (and LV=-c) if the environment variable
 426# LESS (and LV) is not set, respectively".
 427#
 428# Define TEST_SHELL_PATH if you want to use a shell besides SHELL_PATH for
 429# running the test scripts (e.g., bash has better support for "set -x"
 430# tracing).
 431#
 432# When cross-compiling, define HOST_CPU as the canonical name of the CPU on
 433# which the built Git will run (for instance "x86_64").
 434#
 435# Define DEVELOPER to enable more compiler warnings. Compiler version
 436# and family are auto detected, but could be overridden by defining
 437# COMPILER_FEATURES (see config.mak.dev)
 438#
 439# When DEVELOPER is set, DEVOPTS can be used to control compiler
 440# options.  This variable contains keywords separated by
 441# whitespace. The following keywords are are recognized:
 442#
 443#    no-error:
 444#
 445#        suppresses the -Werror that implicitly comes with
 446#        DEVELOPER=1. Useful for getting the full set of errors
 447#        without immediately dying, or for logging them.
 448#
 449#    extra-all:
 450#
 451#        The DEVELOPER mode enables -Wextra with a few exceptions. By
 452#        setting this flag the exceptions are removed, and all of
 453#        -Wextra is used.

1880#   we need to list that dependency for the "foo.o" target.
1881#
1882#   We also list it from other targets that are built from foo.c
1883#   like "foo.sp" and "foo.s", even though that is easy to forget
1884#   to do because the generated header is already present around
1885#   after a regular build attempt.
1886#
1887# - Some code depends on configuration kept in makefile
1888#   variables. The target-specific variable EXTRA_CPPFLAGS can
1889#   be used to convey that information to the C preprocessor
1890#   using -D options.
1891#
1892#   The "foo.o" target should have a corresponding dependency on
1893#   a file that changes when the value of the makefile variable
1894#   changes.  For example, targets making use of the
1895#   $(GIT_VERSION) variable depend on GIT-VERSION-FILE.
1896#
1897#   Technically the ".sp" and ".s" targets do not need this
1898#   dependency because they are force-built, but they get the
1899#   same dependency for consistency. This way, you do not have to
1900#   know how each target is implemented. And it means the
1901#   dependencies here will not need to change if the force-build
1902#   details change some day.
