Makefileon commit Merge branch 'dl/format-patch-notes-config' (e91f65d)
   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# USE_LIBPCRE is a synonym for USE_LIBPCRE2, define USE_LIBPCRE1
  33# instead if you'd like to use the legacy version 1 of the PCRE
  34# library. Support for version 1 will likely be removed in some future
  35# release of Git, as upstream has all but abandoned it.
  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 CURL_LDFLAGS to specify flags that you need to link when using libcurl,
  63# if you do not want to rely on the libraries provided by CURL_CONFIG.  The
  64# default value is a result of `curl-config --libs`.  An example value for
  65# CURL_LDFLAGS is as follows:
  66#
  67#     CURL_LDFLAGS=-lcurl
  68#
  69# Define NO_EXPAT if you do not have expat installed.  git-http-push is
  70# not built, and you cannot push using http:// and https:// transports (dumb).
  71#
  72# Define EXPATDIR=/foo/bar if your expat header and library files are in
  73# /foo/bar/include and /foo/bar/lib directories.
  74#
  75# Define EXPAT_NEEDS_XMLPARSE_H if you have an old version of expat (e.g.,
  76# 1.1 or 1.2) that provides xmlparse.h instead of expat.h.
  77#
  78# Define NO_GETTEXT if you don't want Git output to be translated.
  79# A translated Git requires GNU libintl or another gettext implementation,
  80# plus libintl-perl at runtime.
  81#
  82# Define USE_GETTEXT_SCHEME and set it to 'fallthrough', if you don't trust
  83# the installed gettext translation of the shell scripts output.
  84#
  85# Define HAVE_LIBCHARSET_H if you haven't set NO_GETTEXT and you can't
  86# trust the langinfo.h's nl_langinfo(CODESET) function to return the
  87# current character set. GNU and Solaris have a nl_langinfo(CODESET),
  88# FreeBSD can use either, but MinGW and some others need to use
  89# libcharset.h's locale_charset() instead.
  90#
  91# Define CHARSET_LIB to the library you need to link with in order to
  92# use locale_charset() function.  On some platforms this needs to set to
  93# -lcharset, on others to -liconv .
  94#
  95# Define LIBC_CONTAINS_LIBINTL if your gettext implementation doesn't
  96# need -lintl when linking.
  97#
  98# Define NO_MSGFMT_EXTENDED_OPTIONS if your implementation of msgfmt
  99# doesn't support GNU extensions like --check and --statistics
 100#
 101# Define HAVE_PATHS_H if you have paths.h and want to use the default PATH
 102# it specifies.
 103#
 104# Define NO_D_TYPE_IN_DIRENT if your platform defines DT_UNKNOWN but lacks
 105# d_type in struct dirent (Cygwin 1.5, fixed in Cygwin 1.7).
 106#
 107# Define HAVE_STRINGS_H if you have strings.h and need it for strcasecmp.
 108#
 109# Define NO_STRCASESTR if you don't have strcasestr.
 110#
 111# Define NO_MEMMEM if you don't have memmem.
 112#
 113# Define NO_GETPAGESIZE if you don't have getpagesize.
 114#
 115# Define NO_STRLCPY if you don't have strlcpy.
 116#
 117# Define NO_STRTOUMAX if you don't have both strtoimax and strtoumax in the
 118# C library. If your compiler also does not support long long or does not have
 119# strtoull, define NO_STRTOULL.
 120#
 121# Define NO_SETENV if you don't have setenv in the C library.
 122#
 123# Define NO_UNSETENV if you don't have unsetenv in the C library.
 124#
 125# Define NO_MKDTEMP if you don't have mkdtemp in the C library.
 126#
 127# Define MKDIR_WO_TRAILING_SLASH if your mkdir() can't deal with trailing slash.
 128#
 129# Define NO_GECOS_IN_PWENT if you don't have pw_gecos in struct passwd
 130# in the C library.
 131#
 132# Define NO_LIBGEN_H if you don't have libgen.h.
 133#
 134# Define NEEDS_LIBGEN if your libgen needs -lgen when linking
 135#
 136# Define NO_SYS_SELECT_H if you don't have sys/select.h.
 137#
 138# Define NO_SYMLINK_HEAD if you never want .git/HEAD to be a symbolic link.
 139# Enable it on Windows.  By default, symrefs are still used.
 140#
 141# Define NO_SVN_TESTS if you want to skip time-consuming SVN interoperability
 142# tests.  These tests take up a significant amount of the total test time
 143# but are not needed unless you plan to talk to SVN repos.
 144#
 145# Define NO_FINK if you are building on Darwin/Mac OS X, have Fink
 146# installed in /sw, but don't want GIT to link against any libraries
 147# installed there.  If defined you may specify your own (or Fink's)
 148# include directories and library directories by defining CFLAGS
 149# and LDFLAGS appropriately.
 150#
 151# Define NO_DARWIN_PORTS if you are building on Darwin/Mac OS X,
 152# have DarwinPorts installed in /opt/local, but don't want GIT to
 153# link against any libraries installed there.  If defined you may
 154# specify your own (or DarwinPort's) include directories and
 155# library directories by defining CFLAGS and LDFLAGS appropriately.
 156#
 157# Define NO_APPLE_COMMON_CRYPTO if you are building on Darwin/Mac OS X
 158# and do not want to use Apple's CommonCrypto library.  This allows you
 159# to provide your own OpenSSL library, for example from MacPorts.
 160#
 161# Define BLK_SHA1 environment variable to make use of the bundled
 162# optimized C SHA1 routine.
 163#
 164# Define PPC_SHA1 environment variable when running make to make use of
 165# a bundled SHA1 routine optimized for PowerPC.
 166#
 167# Define DC_SHA1 to unconditionally enable the collision-detecting sha1
 168# algorithm. This is slower, but may detect attempted collision attacks.
 169# Takes priority over other *_SHA1 knobs.
 170#
 171# Define DC_SHA1_EXTERNAL in addition to DC_SHA1 if you want to build / link
 172# git with the external SHA1 collision-detect library.
 173# Without this option, i.e. the default behavior is to build git with its
 174# own built-in code (or submodule).
 175#
 176# Define DC_SHA1_SUBMODULE in addition to DC_SHA1 to use the
 177# sha1collisiondetection shipped as a submodule instead of the
 178# non-submodule copy in sha1dc/. This is an experimental option used
 179# by the git project to migrate to using sha1collisiondetection as a
 180# submodule.
 181#
 182# Define OPENSSL_SHA1 environment variable when running make to link
 183# with the SHA1 routine from openssl library.
 184#
 185# Define SHA1_MAX_BLOCK_SIZE to limit the amount of data that will be hashed
 186# in one call to the platform's SHA1_Update(). e.g. APPLE_COMMON_CRYPTO
 187# wants 'SHA1_MAX_BLOCK_SIZE=1024L*1024L*1024L' defined.
 188#
 189# Define BLK_SHA256 to use the built-in SHA-256 routines.
 190#
 191# Define GCRYPT_SHA256 to use the SHA-256 routines in libgcrypt.
 192#
 193# Define OPENSSL_SHA256 to use the SHA-256 routines in OpenSSL.
 194#
 195# Define NEEDS_CRYPTO_WITH_SSL if you need -lcrypto when using -lssl (Darwin).
 196#
 197# Define NEEDS_SSL_WITH_CRYPTO if you need -lssl when using -lcrypto (Darwin).
 198#
 199# Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
 200#
 201# Define NEEDS_LIBINTL_BEFORE_LIBICONV if you need libintl before libiconv.
 202#
 203# Define NO_INTPTR_T if you don't have intptr_t or uintptr_t.
 204#
 205# Define NO_UINTMAX_T if you don't have uintmax_t.
 206#
 207# Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
 208# Patrick Mauritz).
 209#
 210# Define NEEDS_RESOLV if linking with -lnsl and/or -lsocket is not enough.
 211# Notably on Solaris hstrerror resides in libresolv and on Solaris 7
 212# inet_ntop and inet_pton additionally reside there.
 213#
 214# Define NO_MMAP if you want to avoid mmap.
 215#
 216# Define MMAP_PREVENTS_DELETE if a file that is currently mmapped cannot be
 217# deleted or cannot be replaced using rename().
 218#
 219# Define NO_POLL_H if you don't have poll.h.
 220#
 221# Define NO_SYS_POLL_H if you don't have sys/poll.h.
 222#
 223# Define NO_POLL if you do not have or don't want to use poll().
 224# This also implies NO_POLL_H and NO_SYS_POLL_H.
 225#
 226# Define NEEDS_SYS_PARAM_H if you need to include sys/param.h to compile,
 227# *PLEASE* REPORT to git@vger.kernel.org if your platform needs this;
 228# we want to know more about the issue.
 229#
 230# Define NO_PTHREADS if you do not have or do not want to use Pthreads.
 231#
 232# Define NO_PREAD if you have a problem with pread() system call (e.g.
 233# cygwin1.dll before v1.5.22).
 234#
 235# Define NO_SETITIMER if you don't have setitimer()
 236#
 237# Define NO_STRUCT_ITIMERVAL if you don't have struct itimerval
 238# This also implies NO_SETITIMER
 239#
 240# Define NO_FAST_WORKING_DIRECTORY if accessing objects in pack files is
 241# generally faster on your platform than accessing the working directory.
 242#
 243# Define NO_TRUSTABLE_FILEMODE if your filesystem may claim to support
 244# the executable mode bit, but doesn't really do so.
 245#
 246# Define NEEDS_MODE_TRANSLATION if your OS strays from the typical file type
 247# bits in mode values (e.g. z/OS defines I_SFMT to 0xFF000000 as opposed to the
 248# usual 0xF000).
 249#
 250# Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
 251#
 252# Define NO_UNIX_SOCKETS if your system does not offer unix sockets.
 253#
 254# Define NO_SOCKADDR_STORAGE if your platform does not have struct
 255# sockaddr_storage.
 256#
 257# Define NO_ICONV if your libc does not properly support iconv.
 258#
 259# Define OLD_ICONV if your library has an old iconv(), where the second
 260# (input buffer pointer) parameter is declared with type (const char **).
 261#
 262# Define ICONV_OMITS_BOM if your iconv implementation does not write a
 263# byte-order mark (BOM) when writing UTF-16 or UTF-32 and always writes in
 264# big-endian format.
 265#
 266# Define NO_DEFLATE_BOUND if your zlib does not have deflateBound.
 267#
 268# Define NO_R_TO_GCC_LINKER if your gcc does not like "-R/path/lib"
 269# that tells runtime paths to dynamic libraries;
 270# "-Wl,-rpath=/path/lib" is used instead.
 271#
 272# Define NO_NORETURN if using buggy versions of gcc 4.6+ and profile feedback,
 273# as the compiler can crash (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49299)
 274#
 275# Define USE_NSEC below if you want git to care about sub-second file mtimes
 276# and ctimes. Note that you need recent glibc (at least 2.2.4) for this. On
 277# Linux, kernel 2.6.11 or newer is required for reliable sub-second file times
 278# on file systems with exactly 1 ns or 1 s resolution. If you intend to use Git
 279# on other file systems (e.g. CEPH, CIFS, NTFS, UDF), don't enable USE_NSEC. See
 280# Documentation/technical/racy-git.txt for details.
 281#
 282# Define USE_ST_TIMESPEC if your "struct stat" uses "st_ctimespec" instead of
 283# "st_ctim"
 284#
 285# Define NO_NSEC if your "struct stat" does not have "st_ctim.tv_nsec"
 286# available.  This automatically turns USE_NSEC off.
 287#
 288# Define USE_STDEV below if you want git to care about the underlying device
 289# change being considered an inode change from the update-index perspective.
 290#
 291# Define NO_ST_BLOCKS_IN_STRUCT_STAT if your platform does not have st_blocks
 292# field that counts the on-disk footprint in 512-byte blocks.
 293#
 294# Define DOCBOOK_XSL_172 if you want to format man pages with DocBook XSL v1.72
 295# (not v1.73 or v1.71).
 296#
 297# Define ASCIIDOC_ROFF if your DocBook XSL does not escape raw roff directives
 298# (versions 1.68.1 through v1.72).
 299#
 300# Define GNU_ROFF if your target system uses GNU groff.  This forces
 301# apostrophes to be ASCII so that cut&pasting examples to the shell
 302# will work.
 303#
 304# Define USE_ASCIIDOCTOR to use Asciidoctor instead of AsciiDoc to build the
 305# documentation.
 306#
 307# Define ASCIIDOCTOR_EXTENSIONS_LAB to point to the location of the Asciidoctor
 308# Extensions Lab if you have it available.
 309#
 310# Define PERL_PATH to the path of your Perl binary (usually /usr/bin/perl).
 311#
 312# Define NO_PERL if you do not want Perl scripts or libraries at all.
 313#
 314# Define NO_PERL_CPAN_FALLBACKS if you do not want to install bundled
 315# copies of CPAN modules that serve as a fallback in case the modules
 316# are not available on the system. This option is intended for
 317# distributions that want to use their packaged versions of Perl
 318# modules, instead of the fallbacks shipped with Git.
 319#
 320# Define PYTHON_PATH to the path of your Python binary (often /usr/bin/python
 321# but /usr/bin/python2.7 on some platforms).
 322#
 323# Define NO_PYTHON if you do not want Python scripts or libraries at all.
 324#
 325# Define NO_TCLTK if you do not want Tcl/Tk GUI.
 326#
 327# Define SANE_TEXT_GREP to "-a" if you use recent versions of GNU grep
 328# and egrep that are pickier when their input contains non-ASCII data.
 329#
 330# The TCL_PATH variable governs the location of the Tcl interpreter
 331# used to optimize git-gui for your system.  Only used if NO_TCLTK
 332# is not set.  Defaults to the bare 'tclsh'.
 333#
 334# The TCLTK_PATH variable governs the location of the Tcl/Tk interpreter.
 335# If not set it defaults to the bare 'wish'. If it is set to the empty
 336# string then NO_TCLTK will be forced (this is used by configure script).
 337#
 338# Define INTERNAL_QSORT to use Git's implementation of qsort(), which
 339# is a simplified version of the merge sort used in glibc. This is
 340# recommended if Git triggers O(n^2) behavior in your platform's qsort().
 341#
 342# Define HAVE_ISO_QSORT_S if your platform provides a qsort_s() that's
 343# compatible with the one described in C11 Annex K.
 344#
 345# Define UNRELIABLE_FSTAT if your system's fstat does not return the same
 346# information on a not yet closed file that lstat would return for the same
 347# file after it was closed.
 348#
 349# Define OBJECT_CREATION_USES_RENAMES if your operating systems has problems
 350# when hardlinking a file to another name and unlinking the original file right
 351# away (some NTFS drivers seem to zero the contents in that scenario).
 352#
 353# Define INSTALL_SYMLINKS if you prefer to have everything that can be
 354# symlinked between bin/ and libexec/ to use relative symlinks between
 355# the two. This option overrides NO_CROSS_DIRECTORY_HARDLINKS and
 356# NO_INSTALL_HARDLINKS which will also use symlinking by indirection
 357# within the same directory in some cases, INSTALL_SYMLINKS will
 358# always symlink to the final target directly.
 359#
 360# Define NO_CROSS_DIRECTORY_HARDLINKS if you plan to distribute the installed
 361# programs as a tar, where bin/ and libexec/ might be on different file systems.
 362#
 363# Define NO_INSTALL_HARDLINKS if you prefer to use either symbolic links or
 364# copies to install built-in git commands e.g. git-cat-file.
 365#
 366# Define USE_NED_ALLOCATOR if you want to replace the platforms default
 367# memory allocators with the nedmalloc allocator written by Niall Douglas.
 368#
 369# Define OVERRIDE_STRDUP to override the libc version of strdup(3).
 370# This is necessary when using a custom allocator in order to avoid
 371# crashes due to allocation and free working on different 'heaps'.
 372# It's defined automatically if USE_NED_ALLOCATOR is set.
 373#
 374# Define NO_REGEX if your C library lacks regex support with REG_STARTEND
 375# feature.
 376#
 377# Define HAVE_DEV_TTY if your system can open /dev/tty to interact with the
 378# user.
 379#
 380# Define JSMIN to point to JavaScript minifier that functions as
 381# a filter to have gitweb.js minified.
 382#
 383# Define CSSMIN to point to a CSS minifier in order to generate a minified
 384# version of gitweb.css
 385#
 386# Define DEFAULT_PAGER to a sensible pager command (defaults to "less") if
 387# you want to use something different.  The value will be interpreted by the
 388# shell at runtime when it is used.
 389#
 390# Define DEFAULT_EDITOR to a sensible editor command (defaults to "vi") if you
 391# want to use something different.  The value will be interpreted by the shell
 392# if necessary when it is used.  Examples:
 393#
 394#   DEFAULT_EDITOR='~/bin/vi',
 395#   DEFAULT_EDITOR='$GIT_FALLBACK_EDITOR',
 396#   DEFAULT_EDITOR='"C:\Program Files\Vim\gvim.exe" --nofork'
 397#
 398# Define COMPUTE_HEADER_DEPENDENCIES to "yes" if you want dependencies on
 399# header files to be automatically computed, to avoid rebuilding objects when
 400# an unrelated header file changes.  Define it to "no" to use the hard-coded
 401# dependency rules.  The default is "auto", which means to use computed header
 402# dependencies if your compiler is detected to support it.
 403#
 404# Define NATIVE_CRLF if your platform uses CRLF for line endings.
 405#
 406# Define GIT_USER_AGENT if you want to change how git identifies itself during
 407# network interactions.  The default is "git/$(GIT_VERSION)".
 408#
 409# Define DEFAULT_HELP_FORMAT to "man", "info" or "html"
 410# (defaults to "man") if you want to have a different default when
 411# "git help" is called without a parameter specifying the format.
 412#
 413# Define GIT_TEST_INDEX_VERSION to 2, 3 or 4 to run the test suite
 414# with a different indexfile format version.  If it isn't set the index
 415# file format used is index-v[23].
 416#
 417# Define GMTIME_UNRELIABLE_ERRORS if your gmtime() function does not
 418# return NULL when it receives a bogus time_t.
 419#
 420# Define HAVE_CLOCK_GETTIME if your platform has clock_gettime.
 421#
 422# Define HAVE_CLOCK_MONOTONIC if your platform has CLOCK_MONOTONIC.
 423#
 424# Define NEEDS_LIBRT if your platform requires linking with librt (glibc version
 425# before 2.17) for clock_gettime and CLOCK_MONOTONIC.
 426#
 427# Define USE_PARENS_AROUND_GETTEXT_N to "yes" if your compiler happily
 428# compiles the following initialization:
 429#
 430#   static const char s[] = ("FOO");
 431#
 432# and define it to "no" if you need to remove the parentheses () around the
 433# constant.  The default is "auto", which means to use parentheses if your
 434# compiler is detected to support it.
 435#
 436# Define HAVE_BSD_SYSCTL if your platform has a BSD-compatible sysctl function.
 437#
 438# Define HAVE_GETDELIM if your system has the getdelim() function.
 439#
 440# Define FILENO_IS_A_MACRO if fileno() is a macro, not a real function.
 441#
 442# Define NEED_ACCESS_ROOT_HANDLER if access() under root may success for X_OK
 443# even if execution permission isn't granted for any user.
 444#
 445# Define PAGER_ENV to a SP separated VAR=VAL pairs to define
 446# default environment variables to be passed when a pager is spawned, e.g.
 447#
 448#    PAGER_ENV = LESS=FRX LV=-c
 449#
 450# to say "export LESS=FRX (and LV=-c) if the environment variable
 451# LESS (and LV) is not set, respectively".
 452#
 453# Define TEST_SHELL_PATH if you want to use a shell besides SHELL_PATH for
 454# running the test scripts (e.g., bash has better support for "set -x"
 455# tracing).
 456#
 457# When cross-compiling, define HOST_CPU as the canonical name of the CPU on
 458# which the built Git will run (for instance "x86_64").
 459#
 460# Define RUNTIME_PREFIX to configure Git to resolve its ancillary tooling and
 461# support files relative to the location of the runtime binary, rather than
 462# hard-coding them into the binary. Git installations built with RUNTIME_PREFIX
 463# can be moved to arbitrary filesystem locations. RUNTIME_PREFIX also causes
 464# Perl scripts to use a modified entry point header allowing them to resolve
 465# support files at runtime.
 466#
 467# When using RUNTIME_PREFIX, define HAVE_BSD_KERN_PROC_SYSCTL if your platform
 468# supports the KERN_PROC BSD sysctl function.
 469#
 470# When using RUNTIME_PREFIX, define PROCFS_EXECUTABLE_PATH if your platform
 471# mounts a "procfs" filesystem capable of resolving the path of the current
 472# executable. If defined, this must be the canonical path for the "procfs"
 473# current executable path.
 474#
 475# When using RUNTIME_PREFIX, define HAVE_NS_GET_EXECUTABLE_PATH if your platform
 476# supports calling _NSGetExecutablePath to retrieve the path of the running
 477# executable.
 478#
 479# When using RUNTIME_PREFIX, define HAVE_WPGMPTR if your platform offers
 480# the global variable _wpgmptr containing the absolute path of the current
 481# executable (this is the case on Windows).
 482#
 483# Define DEVELOPER to enable more compiler warnings. Compiler version
 484# and family are auto detected, but could be overridden by defining
 485# COMPILER_FEATURES (see config.mak.dev). You can still set
 486# CFLAGS="..." in combination with DEVELOPER enables, whether that's
 487# for tweaking something unrelated (e.g. optimization level), or for
 488# selectively overriding something DEVELOPER or one of the DEVOPTS
 489# (see just below) brings in.
 490#
 491# When DEVELOPER is set, DEVOPTS can be used to control compiler
 492# options.  This variable contains keywords separated by
 493# whitespace. The following keywords are are recognized:
 494#
 495#    no-error:
 496#
 497#        suppresses the -Werror that implicitly comes with
 498#        DEVELOPER=1. Useful for getting the full set of errors
 499#        without immediately dying, or for logging them.
 500#
 501#    extra-all:
 502#
 503#        The DEVELOPER mode enables -Wextra with a few exceptions. By
 504#        setting this flag the exceptions are removed, and all of
 505#        -Wextra is used.
 506#
 507#    pedantic:
 508#
 509#        Enable -pedantic compilation. This also disables
 510#        USE_PARENS_AROUND_GETTEXT_N to produce only relevant warnings.

2077### Target-specific flags and dependencies
2078
2079# The generic compilation pattern rule and automatically
2080# computed header dependencies (falling back to a dependency on
2081# LIB_H) are enough to describe how most targets should be built,
2082# but some targets are special enough to need something a little
2083# different.
2084#
2085# - When a source file "foo.c" #includes a generated header file,
2086#   we need to list that dependency for the "foo.o" target.
2087#
2088#   We also list it from other targets that are built from foo.c
2089#   like "foo.sp" and "foo.s", even though that is easy to forget
2090#   to do because the generated header is already present around
2091#   after a regular build attempt.
2092#
2093# - Some code depends on configuration kept in makefile
2094#   variables. The target-specific variable EXTRA_CPPFLAGS can
2095#   be used to convey that information to the C preprocessor
2096#   using -D options.
2097#
2098#   The "foo.o" target should have a corresponding dependency on
2099#   a file that changes when the value of the makefile variable
2100#   changes.  For example, targets making use of the
2101#   $(GIT_VERSION) variable depend on GIT-VERSION-FILE.
2102#
2103#   Technically the ".sp" and ".s" targets do not need this
2104#   dependency because they are force-built, but they get the
2105#   same dependency for consistency. This way, you do not have to
2106#   know how each target is implemented. And it means the
2107#   dependencies here will not need to change if the force-build
2108#   details change some day.
