Makefile revision 1.5 1 # Make and install tzdb code and data.
2 # This file is in the public domain, so clarified as of
3 # 2009-05-17 by Arthur David Olson.
4 # Request POSIX conformance; this must be the first non-comment line.
5 .POSIX:
6 # By default, builds of code and data assume POSIX.1-2001 or later;
7 # this assumption can be relaxed by tailoring the build as described below.
8 # On older platforms you may need to scrounge for POSIX conformance.
9 # For example, on Solaris 10 (2005) with Sun Studio 12 aka Sun C 5.9 (2007),
10 # use 'PATH=/usr/xpg4/bin:$PATH make CC=c99'.
11 # Reproducible builds of distribution tarballs also need a copy of the
12 # Git repository, and assume the behavior of the following programs
13 # (or later versions):
14 # Git 2.7.0 (2016)
15 # GNU Coreutils 6.3 (2006)
16 # GNU Tar 1.14 (2004)
17 # GnuPG 1.4 (2004)
18 # Although tzdb does not come with a software bill of materials,
19 # you should be able to construct one based on the above information,
20 # your platform, and the way you use this Makefile.
21
22 # To affect how this Makefile works, you can run a shell script like this:
23 #
24 # #!/bin/sh
25 # make CFLAGS='-O2 -DHAVE_GETTEXT=0' "$@"
26 #
27 # This example script is appropriate for a GNU/Linux system
28 # which needs more optimization than default, and which does not want
29 # gettext's internationalization of diagnostics.
30 #
31 # Alternatively, you can simply edit this Makefile to tailor the following
32 # macro definitions.

132 # If you want only POSIX time, with time values interpreted as
133 # seconds since the epoch (not counting leap seconds), use

135 # below. If you want only "right" time, with values interpreted
136 # as seconds since the epoch (counting leap seconds), use

147 # leap smearing; this can work better than unsmeared "right" time with

277 # -DMKTIME_MIGHT_OVERFLOW if mktime might fail due to time_t overflow
278 # -DOPENAT_TZDIR if tzset should use openat on TZDIR then a relative open.
279 # See localtime.c for details.
280 # -DPORT_TO_C89 if tzcode should also run on mostly-C89 platforms+
281 # Typically it is better to use a later standard. For example,
282 # with GCC 4.9.4 (2016), prefer '-std=gnu11' to '-DPORT_TO_C89'.
283 # Even with -DPORT_TO_C89, the code needs at least one C99
284 # feature (integers at least 64 bits wide) and maybe more.
285 # -DRESERVE_STD_EXT_IDS if your platform reserves standard identifiers
286 # with external linkage, e.g., applications cannot define 'localtime'.
287 # -Dssize_t=int on hosts like MS-Windows that lack ssize_t
288 # -DSUPPORT_C89=0 if the tzcode library should not support C89 callers
289 # Although -DSUPPORT_C89=0 might work around latent bugs in callers,
290 # it does not conform to POSIX.
291 # -DSUPPORT_POSIX2008 if the library should support older POSIX callers+
292 # However, this might cause problems in POSIX.1-2024-or-later callers.
293 # -DSUPPRESS_TZDIR to not prepend TZDIR to file names; this has
294 # security implications and is not recommended for general use
295 # -DTHREAD_SAFE to make localtime.c thread-safe, as POSIX requires;
296 # not needed by the main-program tz code, which is single-threaded.
297 # Append other compiler flags as needed, e.g., -pthread on GNU/Linux.
298 # The following options can also be used:
299 # -DTHREAD_PREFER_SINGLE to prefer speed in single-threaded apps,
300 # at some cost in CPU time and energy in multi-threaded apps.
301 # The following options can also be used:
302 # -DHAVE___ISTHREADED=1 if there is an extern int __isthreaded
303 # variable, 0 otherwise (default is guessed)
304 # -DHAVE_SYS_SINGLE_THREADED_H=0 if <sys/single_threaded.h> works,
305 # 0 otherwise (default is guessed)
306 # -DTHREAD_RWLOCK to use read-write locks instead of mutexes.
307 # This can improve parallelism and thus save real time
308 # if many threads call tzcode functions simultaneously.
309 # It also costs CPU time and thus energy.
310 # -DTHREAD_TM_MULTI to have gmtime, localtime, and offtime
311 # return different struct tm * addresses in different threads.
312 # This supports nonportable programs that call
313 # gmtime/localtime/offtime when they should call
314 # gmtime_r/localtime_r/offtime_r to avoid races.
315 # Because the corresponding storage is freed on thread exit,
316 # this option is incompatible with POSIX.1-2024 and earlier.
317 # It also costs CPU time and memory.
318 # -Dtime_tz=\"T\" to use T as the time_t type, rather than the system time_t
319 # This is intended for internal use only; it mangles external names.
320 # -DTZ_CHANGE_INTERVAL=N if functions depending on TZ should check
321 # no more often than every N seconds for TZif file changes.
322 # If N is negative (the default), no such checking is done.
323 # This option is intended for platforms that want localtime etc.
324 # to respond to changes to a file selected by TZ, including to
325 # TZDEFAULT (normally /etc/localtime) if TZ is unset.
326 # On these platforms, REDO should be "posix_only" or "posix_right".
327 # This option does not affect tzalloc-allocated objects.
328 # -DTZ_DOMAIN=\"foo\" to use "foo" for gettext domain name; default is "tz"
329 # -DTZ_DOMAINDIR=\"/path\" to use "/path" for gettext directory;
330 # the default is system-supplied, typically "/usr/lib/locale"
331 # -DTZ_RUNTIME_LEAPS=0 to disable runtime support for leap seconds.
332 # This conforms to POSIX, shrinks tzcode's attack surface,
333 # and is more efficient. However, it fails to support Internet
334 # RFC 9636's leap seconds.
335 # -DTZDEFRULESTRING=\",date/time,date/time\" to default to the specified
336 # DST transitions for proleptic format TZ strings lacking them.
337 # If not specified, it defaults to US rules for future DST transitions.
338 # This mishandles some past timestamps, as US DST rules have changed.
339 # It also mishandles settings like TZ='EET-2EEST' for eastern Europe,
340 # as Europe and US DST rules differ.
341 # -DTZNAME_MAXIMUM=N to limit time zone abbreviations to N bytes (default 254)
342 # -DUNINIT_TRAP if reading uninitialized storage can cause problems
343 # other than simply getting garbage data
344 # -DUSE_LTZ=0 to build zdump with the system time zone library
345 # Also set TZDOBJS=zdump.o and CHECK_TIME_T_ALTERNATIVES= below.
346 # -DZIC_BLOAT_DEFAULT=\"fat\" to default zic's -b option to "fat", and
347 # similarly for "slim". Fat TZif files work around incompatibilities
348 # and bugs in some TZif readers, notably older ones that
349 # ignore or otherwise mishandle 64-bit data in TZif files;
350 # however, fat TZif files may trigger bugs in newer TZif readers.
351 # Slim TZif files are more efficient, and are the default.
352 # -DZIC_MAX_ABBR_LEN_WO_WARN=3
353 # (or some other number) to set the maximum time zone abbreviation length
354 # that zic will accept without a warning (the default is 6)
355 # -g to generate symbolic debugging info
356 # -Idir to include from directory 'dir'
357 # -O0 to disable optimization; other -O options to enable more optimization
358 # -Uname to remove any definition of the macro 'name'
359 # $(GCC_DEBUG_FLAGS) if you are using recent GCC and want lots of checking

418 # # and the variable is planned to be removed in a future POSIX edition.
419 # # If not defined, the code attempts to guess HAVE_TZNAME from other macros.
420 # # Warning: unless time_tz is also defined, HAVE_TZNAME=1 can cause
421 # # crashes when combined with some platforms' standard libraries,

442 # If you want functions that were inspired by early versions of X3J11's work,

444 # -DSTD_INSPIRED
445 # to the end of the "CFLAGS=" line. This arranges for the following
446 # functions to be added to the time conversion library.
447 # "offtime" is like "gmtime" except that it accepts a second (long) argument
448 # that gives an offset to add to the time_t when converting it.
449 # "offtime_r" is to "offtime" what "gmtime_r" is to "gmtime".
450 # I.e., "offtime" and "offtime_r" are like calling "localtime_rz"
451 # with a fixed-offset zone.
452 # "timelocal" is nearly equivalent to "mktime".
453 # "timeoff" is like "timegm" except that it accepts a second (long) argument
454 # that gives an offset to use when converting to a time_t.
455 # I.e., "timeoff" is like calling "mktime_z" with a fixed-offset zone.
456 # "posix2time" and "time2posix" are described in an included manual page.
457 # X3J11's work does not describe any of these functions.
458 # These functions may well disappear in future releases of the time
459 # conversion package.
460 #
461 # If you don't want functions that were inspired by NetBSD, add
462 # -DNETBSD_INSPIRED=0
463 # to the end of the "CFLAGS=" line. Otherwise, the functions
464 # "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the
465 # time library, and if STD_INSPIRED is also defined to nonzero the functions
466 # "posix2time_z" and "time2posix_z" are added as well.
467 # The functions ending in "_z" (or "_rz") are like their unsuffixed
468 # (or suffixed-by-"_r") counterparts, except with an extra first
469 # argument of opaque type timezone_t that specifies the timezone.
470 # "tzalloc" allocates a timezone_t value, and "tzfree" frees it.
471 #

1339 # useful for testing whether TZUpdater supports vanguard form.
1340 # The generated tarball is not byte-for-byte equivalent to a hand-tailored
1341 # traditional tarball, as data entries are put into 'etcetera' even if they
1342 # came from some other source file. However, the effect should be the same
1343 # for ordinary use, which reads all the source files.
