Makefile revision 1.56
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 # On older platforms you may need to scrounge for a POSIX-conforming 'make'. 7 # For example, on Solaris 10 (2005), use /usr/sfw/bin/gmake or 8 # /usr/xpg4/bin/make, not /usr/ccs/bin/make. 9 10 # To affect how this Makefile works, you can run a shell script like this: 11 # 12 # #!/bin/sh 13 # make CC='gcc -std=gnu11' "$@" 14 # 15 # This example script is appropriate for a pre-2017 GNU/Linux system 16 # where a non-default setting is needed to support this package's use of C99. 17 # 18 # Alternatively, you can simply edit this Makefile to tailor the following 19 # macro definitions. 20 21 ############################################################################### 22 # Start of macros that one plausibly might want to tailor. 23 24 # Package name for the code distribution. 25 PACKAGE= tzcode 26 27 # Version number for the distribution, overridden in the 'tarballs' rule below. 28 VERSION= unknown 29 30 # Email address for bug reports. 31 BUGEMAIL= tz@iana.org 32 33 # DATAFORM selects the data format. 34 # Available formats represent essentially the same data, albeit 35 # possibly with minor discrepancies that users are not likely to notice. 36 # To get new features and the best data right away, use: 37 # DATAFORM= vanguard 38 # To wait a while before using new features, to give downstream users 39 # time to upgrade zic (the default), use: 40 # DATAFORM= main 41 # To wait even longer for new features, use: 42 # DATAFORM= rearguard 43 # Rearguard users might also want "ZFLAGS = -b fat"; see below. 44 DATAFORM= main 45 46 # Change the line below for your timezone (after finding the one you want in 47 # one of the $(TDATA) source files, or adding it to a source file). 48 # Alternatively, if you discover you've got the wrong timezone, you can just 49 # 'zic -l -' to remove it, or 'zic -l rightzone' to change it. 50 # Use the command 51 # make zonenames 52 # to get a list of the values you can use for LOCALTIME. 53 54 LOCALTIME= Factory 55 56 # The POSIXRULES macro controls interpretation of POSIX-like TZ 57 # settings like TZ='EET-2EEST' that lack DST transition rules. 58 # If POSIXRULES is '-', no template is installed; this is the default. 59 # Any other value for POSIXRULES is obsolete and should not be relied on, as: 60 # * It does not work correctly in popular implementations such as GNU/Linux. 61 # * It does not work even in tzcode, except for historical timestamps 62 # that precede the last explicit transition in the POSIXRULES file. 63 # Hence it typically does not work for current and future timestamps. 64 # If, despite the above, you want a template for handling these settings, 65 # you can change the line below (after finding the timezone you want in the 66 # one of the $(TDATA) source files, or adding it to a source file). 67 # Alternatively, if you discover you've got the wrong timezone, you can just 68 # 'zic -p -' to remove it, or 'zic -p rightzone' to change it. 69 # Use the command 70 # make zonenames 71 # to get a list of the values you can use for POSIXRULES. 72 73 POSIXRULES= - 74 75 # Also see TZDEFRULESTRING below, which takes effect only 76 # if POSIXRULES is '-' or if the template file cannot be accessed. 77 78 79 # Installation locations. 80 # 81 # The defaults are suitable for Debian, except that if REDO is 82 # posix_right or right_posix then files that Debian puts under 83 # /usr/share/zoneinfo/posix and /usr/share/zoneinfo/right are instead 84 # put under /usr/share/zoneinfo-posix and /usr/share/zoneinfo-leaps, 85 # respectively.

POSIX mandates that leap seconds not be counted; for compatibility 153 # with it, use "posix_only" or "posix_right". Use POSIX time on systems with 154 # leap smearing; this can work better than unsmeared "right" time with 155 # applications that are not leap second aware, and is closer to unsmeared 156 # "right" time than unsmeared POSIX time is (e.g., 0.5 vs 1.0 s max error). 157 158 REDO= posix_right 159 160 # Whether to put an "Expires" line in the leapseconds file. 161 # Use EXPIRES_LINE=1 to put the line in, 0 to omit it. 162 # The EXPIRES_LINE value matters only if REDO's value contains "right". 163 # If you change EXPIRES_LINE, remove the leapseconds file before running "make". 164 # zic's support for the Expires line was introduced in tzdb 2020a, 165 # and was modified in tzdb 2021b to generate version 4 TZif files. 166 # EXPIRES_LINE defaults to 0 for now so that the leapseconds file 167 # can be given to pre-2020a zic implementations and so that TZif files 168 # built by newer zic implementations can be read by pre-2021b libraries. 169 EXPIRES_LINE= 0 170 171 # To install data in text form that has all the information of the TZif data, 172 # (optionally incorporating leap second information), use 173 # TZDATA_TEXT= tzdata.zi leapseconds 174 # To install text data without leap second information (e.g., because 175 # REDO='posix_only'), use 176 # TZDATA_TEXT= tzdata.zi 177 # To avoid installing text data, use 178 # TZDATA_TEXT= 179 180 TZDATA_TEXT= leapseconds tzdata.zi 181 182 # For backward-compatibility links for old zone names, use 183 # BACKWARD= backward 184 # To omit these links, use 185 # BACKWARD= 186 187 BACKWARD= backward 188 189 # If you want out-of-scope and often-wrong data from the file 'backzone', 190 # but only for entries listed in the backward-compatibility file zone.tab, use 191 # PACKRATDATA= backzone 192 # PACKRATLIST= zone.tab 193 # If you want all the 'backzone' data, use 194 # PACKRATDATA= backzone 195 # PACKRATLIST= 196 # To omit this data, use 197 # PACKRATDATA= 198 # PACKRATLIST= 199 200 PACKRATDATA= 201 PACKRATLIST= 202 203 # The name of a locale using the UTF-8 encoding, used during self-tests. 204 # The tests are skipped if the name does not appear to work on this system. 205 206 UTF8_LOCALE= en_US.utf8 207 208 # Non-default libraries needed to link. 209 # On some hosts, this should have -lintl unless CFLAGS has -DHAVE_GETTEXT=0. 210 LDLIBS= 211 212 # Add the following to an uncommented "CFLAGS=" line as needed 213 # to override defaults specified in the source code or by the system. 214 # "-DFOO" is equivalent to "-DFOO=1". 215 # -DDEPRECATE_TWO_DIGIT_YEARS for optional runtime warnings about strftime 216 # formats that generate only the last two digits of year numbers 217 # -DEPOCH_LOCAL if the 'time' function returns local time not UT 218 # -DEPOCH_OFFSET=N if the 'time' function returns a value N greater 219 # than what POSIX specifies, assuming local time is UT. 220 # For example, N is 252460800 on AmigaOS. 221 # -DHAVE_DECL_ASCTIME_R=0 if <time.h> does not declare asctime_r 222 # -DHAVE_DECL_ENVIRON if <unistd.h> declares 'environ' 223 # -DHAVE_DECL_TIMEGM=0 if <time.h> does not declare timegm 224 # -DHAVE_DIRECT_H if mkdir needs <direct.h> (MS-Windows) 225 # -DHAVE__GENERIC=0 if _Generic does not work* 226 # -DHAVE_GETRANDOM if getrandom works (e.g., GNU/Linux), 227 # -DHAVE_GETRANDOM=0 to avoid using getrandom 228 # -DHAVE_GETTEXT if gettext works (e.g., GNU/Linux, FreeBSD, Solaris), 229 # where LDLIBS also needs to contain -lintl on some hosts;

Otherwise, the functions 397 # "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the 398 # time library, and if STD_INSPIRED is also defined to nonzero the functions 399 # "posix2time_z" and "time2posix_z" are added as well. 400 # The functions ending in "_z" (or "_rz") are like their unsuffixed 401 # (or suffixed-by-"_r") counterparts, except with an extra first 402 # argument of opaque type timezone_t that specifies the timezone. 403 # "tzalloc" allocates a timezone_t value, and "tzfree" frees it. 404 # 405 # If you want to allocate state structures in localtime, add 406 # -DALL_STATE 407 # to the end of the "CFLAGS=" line.
