Makefile

   1 # The default target of this Makefile is...
   2 all::
   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

 465 # support files at runtime.

 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.

2079 ### Target-specific flags and dependencies
2080
2081 # The generic compilation pattern rule and automatically
2082 # computed header dependencies (falling back to a dependency on
2083 # LIB_H) are enough to describe how most targets should be built,
2084 # but some targets are special enough to need something a little
2085 # different.
2086 #
2087 # - When a source file "foo.c" #includes a generated header file,
2088 #   we need to list that dependency for the "foo.o" target.
2089 #
2090 #   We also list it from other targets that are built from foo.c
2091 #   like "foo.sp" and "foo.s", even though that is easy to forget
2092 #   to do because the generated header is already present around
2093 #   after a regular build attempt.
2094 #
2095 # - Some code depends on configuration kept in makefile
2096 #   variables. The target-specific variable EXTRA_CPPFLAGS can
2097 #   be used to convey that information to the C preprocessor
2098 #   using -D options.
2099 #
2100 #   The "foo.o" target should have a corresponding dependency on
2101 #   a file that changes when the value of the makefile variable
2102 #   changes.  For example, targets making use of the
2103 #   $(GIT_VERSION) variable depend on GIT-VERSION-FILE.
2104 #
2105 #   Technically the ".sp" and ".s" targets do not need this
2106 #   dependency because they are force-built, but they get the
2107 #   same dependency for consistency. This way, you do not have to
2108 #   know how each target is implemented. And it means the
2109 #   dependencies here will not need to change if the force-build
2110 #   details change some day.
