If you want want only "right" time, with values interpreted 79# as seconds since the epoch (counting leap seconds), use 80# REDO= right_only 81# below. If you want both sets of data available, with leap seconds not 82# counted normally, use 83# REDO= posix_right 84# below. If you want both sets of data available, with leap seconds counted 85# normally, use 86# REDO= right_posix 87# below. POSIX mandates that leap seconds not be counted; for compatibility 88# with it, use "posix_only" or "posix_right". Use POSIX time on systems with 89# leap smearing; this can work better than unsmeared "right" time with 90# applications that are not leap second aware, and is closer to unsmeared 91# "right" time than unsmeared POSIX time is (e.g., 0.5 vs 1.0 s max error). 92 93REDO= posix_right 94 95# If you want out-of-scope and often-wrong data from the file 'backzone', use 96# PACKRATDATA= backzone 97# To omit this data, use 98# PACKRATDATA= 99 100PACKRATDATA= 101 102# Since "." may not be in PATH... 103 104YEARISTYPE= ./yearistype 105 106# Non-default libraries needed to link. 107LDLIBS= 108 109# Add the following to the end of the "CFLAGS=" line as needed. 110# -DBIG_BANG=-9999999LL if the Big Bang occurred at time -9999999 (see zic.c) 111# -DHAVE_DECL_ASCTIME_R=0 if <time.h> does not declare asctime_r 112# -DHAVE_DIRECT_H if mkdir needs <direct.h> (MS-Windows) 113# -DHAVE_DOS_FILE_NAMES if file names have drive specifiers etc. (MS-DOS) 114# -DHAVE_GETTEXT=1 if 'gettext' works (e.g., GNU/Linux, FreeBSD, Solaris) 115# -DHAVE_INCOMPATIBLE_CTIME_R=1 if your system's time.h declares 116# ctime_r and asctime_r incompatibly with the POSIX standard 117# (Solaris when _POSIX_PTHREAD_SEMANTICS is not defined). 118# -DHAVE_INTTYPES_H=1 if you have a pre-C99 compiler with "inttypes.h" 119# -DHAVE_LINK=0 if your system lacks a link function 120# -DHAVE_LOCALTIME_R=0 if your system lacks a localtime_r function 121# -DHAVE_LOCALTIME_RZ=0 if you do not want zdump to use localtime_rz 122# This defaults to 1 if a working localtime_rz seems to be available. 123# localtime_rz can make zdump significantly faster, but is nonstandard. 124# -DHAVE_POSIX_DECLS=0 if your system's include files do not declare 125# functions like 'link' or variables like 'tzname' required by POSIX 126# -DHAVE_STDINT_H=1 if you have a pre-C99 compiler with "stdint.h" 127# -DHAVE_STRFTIME_L=1 if <time.h> declares locale_t and strftime_l 128# This defaults to 0 if _POSIX_VERSION < 200809, 1 otherwise. 129# -DHAVE_STRDUP=0 if your system lacks the strdup function 130# -DHAVE_SYMLINK=0 if your system lacks the symlink function 131# -DHAVE_SYS_STAT_H=0 if your compiler lacks a "sys/stat.h" 132# -DHAVE_SYS_WAIT_H=0 if your compiler lacks a "sys/wait.h" 133# -DHAVE_TZSET=0 if your system lacks a tzset function 134# -DHAVE_UNISTD_H=0 if your compiler lacks a "unistd.h" (Microsoft C++ 7?) 135# -DEPOCH_LOCAL=1 if the 'time' function returns local time not UT 136# -DEPOCH_OFFSET=N if the 'time' function returns a value N greater 137# than what POSIX specifies, assuming local time is UT. 138# For example, N is 252460800 on AmigaOS. 139# -DNO_RUN_TIME_WARNINGS_ABOUT_YEAR_2000_PROBLEMS_THANK_YOU=1 140# if you do not want run time warnings about formats that may cause 141# year 2000 grief 142# -Dssize_t=long on ancient hosts that lack ssize_t 143# -DTHREAD_SAFE=1 to make localtime.c thread-safe, as POSIX requires; 144# not needed by the main-program tz code, which is single-threaded. 145# Append other compiler flags as needed, e.g., -pthread on GNU/Linux. 146# -Dtime_tz=\"T\" to use T as the time_t type, rather than the system time_t 147# -DTZ_DOMAIN=\"foo\" to use "foo" for gettext domain name; default is "tz" 148# -DTZ_DOMAINDIR=\"/path\" to use "/path" for gettext directory; 149# the default is system-supplied, typically "/usr/lib/locale" 150# -DTZDEFRULESTRING=\",date/time,date/time\" to default to the specified 151# DST transitions if the time zone files cannot be accessed 152# -DUNINIT_TRAP=1 if reading uninitialized storage can cause problems 153# other than simply getting garbage data 154# -DUSE_LTZ=0 to build zdump with the system time zone library 155# Also set TZDOBJS=zdump.o and CHECK_TIME_T_ALTERNATIVES= below. 156# -DZIC_MAX_ABBR_LEN_WO_WARN=3 157# (or some other number) to set the maximum time zone abbreviation length 158# that zic will accept without a warning (the default is 6) 159# $(GCC_DEBUG_FLAGS) if you are using recent GCC and want lots of checking 160GCC_DEBUG_FLAGS = -Dlint -g3 -O3 -fno-common -fstrict-aliasing \ 161 -Wall -Wextra \ 162 -Wbad-function-cast -Wcast-align -Wdate-time \ 163 -Wdeclaration-after-statement \ 164 -Wdouble-promotion \ 165 -Wformat=2 -Winit-self -Wjump-misses-init \ 166 -Wlogical-op -Wmissing-prototypes -Wnested-externs \ 167 -Wold-style-definition -Woverlength-strings -Wpointer-arith \ 168 -Wshadow -Wstrict-prototypes -Wsuggest-attribute=const \ 169 -Wsuggest-attribute=format -Wsuggest-attribute=noreturn \ 170 -Wsuggest-attribute=pure -Wtrampolines \ 171 -Wundef -Wunused -Wwrite-strings \ 172 -Wno-address -Wno-format-nonliteral -Wno-sign-compare \ 173 -Wno-type-limits -Wno-unused-parameter 174# 175# If you want to use System V compatibility code, add 176# -DUSG_COMPAT 177# to the end of the "CFLAGS=" line. This arrange for "timezone" and "daylight" 178# variables to be kept up-to-date by the time conversion functions. Neither 179# "timezone" nor "daylight" is described in X3J11's work. 180# 181# If your system has a "GMT offset" field in its "struct tm"s 182# (or if you decide to add such a field in your system's "time.h" file), 183# add the name to a define such as 184# -DTM_GMTOFF=tm_gmtoff 185# to the end of the "CFLAGS=" line. If not defined, the code attempts to 186# guess TM_GMTOFF from other macros; define NO_TM_GMTOFF to suppress this. 187# Similarly, if your system has a "zone abbreviation" field, define 188# -DTM_ZONE=tm_zone 189# and define NO_TM_ZONE to suppress any guessing. These two fields are not 190# required by POSIX, but are widely available on GNU/Linux and BSD systems. 191# 192# If you want functions that were inspired by early versions of X3J11's work, 193# add 194# -DSTD_INSPIRED 195# to the end of the "CFLAGS=" line. This arranges for the functions 196# "tzsetwall", "offtime", "timelocal", "timegm", "timeoff", 197# "posix2time", and "time2posix" to be added to the time conversion library. 198# "tzsetwall" is like "tzset" except that it arranges for local wall clock 199# time (rather than the time specified in the TZ environment variable) 200# to be used. 201# "offtime" is like "gmtime" except that it accepts a second (long) argument 202# that gives an offset to add to the time_t when converting it. 203# "timelocal" is equivalent to "mktime". 204# "timegm" is like "timelocal" except that it turns a struct tm into 205# a time_t using UT (rather than local time as "timelocal" does). 206# "timeoff" is like "timegm" except that it accepts a second (long) argument 207# that gives an offset to use when converting to a time_t. 208# "posix2time" and "time2posix" are described in an included manual page. 209# X3J11's work does not describe any of these functions. 210# Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0. 211# These functions may well disappear in future releases of the time 212# conversion package. 213# 214# If you don't want functions that were inspired by NetBSD, add 215# -DNETBSD_INSPIRED=0 216# to the end of the "CFLAGS=" line. Otherwise, the functions 217# "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the 218# time library, and if STD_INSPIRED is also defined the functions 219# "posix2time_z" and "time2posix_z" are added as well. 220# The functions ending in "_z" (or "_rz") are like their unsuffixed 221# (or suffixed-by-"_r") counterparts, except with an extra first 222# argument of opaque type timezone_t that specifies the time zone. 223# "tzalloc" allocates a timezone_t value, and "tzfree" frees it. 224# 225# If you want to allocate state structures in localtime, add 226# -DALL_STATE 227# to the end of the "CFLAGS=" line. Storage is obtained by calling malloc. 228# 229# If you want an "altzone" variable (a la System V Release 3.1), add 230# -DALTZONE 231# to the end of the "CFLAGS=" line. 232# This variable is not described in X3J11's work. 233# 234# NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put 235# out by the National Institute of Standards and Technology 236# which claims to test C and Posix conformance. If you want to pass PCTS, add 237# -DPCTS 238# to the end of the "CFLAGS=" line. 239# 240# If you want strict compliance with XPG4 as of 1994-04-09, add 241# -DXPG4_1994_04_09 242# to the end of the "CFLAGS=" line. This causes "strftime" to always return 243# 53 as a week number (rather than 52 or 53) for those days in January that 244# before the first Monday in January when a "%V" format is used and January 1 245# falls on a Friday, Saturday, or Sunday. 246 247CFLAGS= 248 249# Linker flags.
