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 93 REDO= 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= 99 100 PACKRATDATA= 101 102 # Since "." may not be in PATH... 103 104 YEARISTYPE= ./yearistype 105 106 # Non-default libraries needed to link. 107 LDLIBS= 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 # -DUNINIT_TRAP=1 if reading uninitialized storage can cause problems 152 # other than simply getting garbage data 153 # -DUSE_LTZ=0 to build zdump with the system time zone library 154 # Also set TZDOBJS=zdump.o and CHECK_TIME_T_ALTERNATIVES= below. 155 # -DNO_ERROR_IN_DST_GAP=1 156 # if you want mktime() not to return an error in the DST gap. 157 # -DZIC_MAX_ABBR_LEN_WO_WARN=3 158 # (or some other number) to set the maximum time zone abbreviation length 159 # that zic will accept without a warning (the default is 6) 160 # $(GCC_DEBUG_FLAGS) if you are using recent GCC and want lots of checking 161 GCC_DEBUG_FLAGS = -Dlint -g3 -O3 -fno-common -fstrict-aliasing \ 162 -Wall -Wextra \ 163 -Wbad-function-cast -Wcast-align -Wdate-time \ 164 -Wdeclaration-after-statement \ 165 -Wdouble-promotion \ 166 -Wformat=2 -Winit-self -Wjump-misses-init \ 167 -Wlogical-op -Wmissing-prototypes -Wnested-externs \ 168 -Wold-style-definition -Woverlength-strings -Wpointer-arith \ 169 -Wshadow -Wstrict-prototypes -Wsuggest-attribute=const \ 170 -Wsuggest-attribute=format -Wsuggest-attribute=noreturn \ 171 -Wsuggest-attribute=pure -Wtrampolines \ 172 -Wundef -Wunused -Wwrite-strings \ 173 -Wno-address -Wno-format-nonliteral -Wno-sign-compare \ 174 -Wno-type-limits -Wno-unused-parameter 175 # 176 # If you want to use System V compatibility code, add 177 # -DUSG_COMPAT 178 # to the end of the "CFLAGS=" line. This arrange for "timezone" and "daylight" 179 # variables to be kept up-to-date by the time conversion functions. Neither 180 # "timezone" nor "daylight" is described in X3J11's work. 181 # 182 # If your system has a "GMT offset" field in its "struct tm"s 183 # (or if you decide to add such a field in your system's "time.h" file), 184 # add the name to a define such as 185 # -DTM_GMTOFF=tm_gmtoff 186 # to the end of the "CFLAGS=" line. If not defined, the code attempts to 187 # guess TM_GMTOFF from other macros; define NO_TM_GMTOFF to suppress this. 188 # Similarly, if your system has a "zone abbreviation" field, define 189 # -DTM_ZONE=tm_zone 190 # and define NO_TM_ZONE to suppress any guessing. These two fields are not 191 # required by POSIX, but are widely available on GNU/Linux and BSD systems. 192 # 193 # If you want functions that were inspired by early versions of X3J11's work, 194 # add 195 # -DSTD_INSPIRED 196 # to the end of the "CFLAGS=" line. This arranges for the functions 197 # "tzsetwall", "offtime", "timelocal", "timegm", "timeoff", 198 # "posix2time", and "time2posix" to be added to the time conversion library. 199 # "tzsetwall" is like "tzset" except that it arranges for local wall clock 200 # time (rather than the time specified in the TZ environment variable) 201 # to be used. 202 # "offtime" is like "gmtime" except that it accepts a second (long) argument 203 # that gives an offset to add to the time_t when converting it. 204 # "timelocal" is equivalent to "mktime". 205 # "timegm" is like "timelocal" except that it turns a struct tm into 206 # a time_t using UT (rather than local time as "timelocal" does). 207 # "timeoff" is like "timegm" except that it accepts a second (long) argument 208 # that gives an offset to use when converting to a time_t. 209 # "posix2time" and "time2posix" are described in an included manual page. 210 # X3J11's work does not describe any of these functions. 211 # Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0. 212 # These functions may well disappear in future releases of the time 213 # conversion package. 214 # 215 # If you don't want functions that were inspired by NetBSD, add 216 # -DNETBSD_INSPIRED=0 217 # to the end of the "CFLAGS=" line. Otherwise, the functions 218 # "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the 219 # time library, and if STD_INSPIRED is also defined the functions 220 # "posix2time_z" and "time2posix_z" are added as well. 221 # The functions ending in "_z" (or "_rz") are like their unsuffixed 222 # (or suffixed-by-"_r") counterparts, except with an extra first 223 # argument of opaque type timezone_t that specifies the time zone. 224 # "tzalloc" allocates a timezone_t value, and "tzfree" frees it. 225 # 226 # If you want to allocate state structures in localtime, add 227 # -DALL_STATE 228 # to the end of the "CFLAGS=" line. Storage is obtained by calling malloc. 229 # 230 # If you want an "altzone" variable (a la System V Release 3.1), add 231 # -DALTZONE 232 # to the end of the "CFLAGS=" line. 233 # This variable is not described in X3J11's work. 234 # 235 # NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put 236 # out by the National Institute of Standards and Technology 237 # which claims to test C and Posix conformance. If you want to pass PCTS, add 238 # -DPCTS 239 # to the end of the "CFLAGS=" line. 240 # 241 # If you want strict compliance with XPG4 as of 1994-04-09, add 242 # -DXPG4_1994_04_09 243 # to the end of the "CFLAGS=" line. This causes "strftime" to always return 244 # 53 as a week number (rather than 52 or 53) for those days in January that 245 # before the first Monday in January when a "%V" format is used and January 1 246 # falls on a Friday, Saturday, or Sunday. 247 248 CFLAGS= 249 250 # Linker flags.
