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. 33 34############################################################################### 35# Start of macros that one plausibly might want to tailor. 36 37# Package name for the code distribution. 38PACKAGE= tzcode 39 40# Version number for the distribution, overridden in the 'tarballs' rule below. 41VERSION= unknown 42 43# Email address for bug reports. 44BUGEMAIL= tz@iana.org 45 46# DATAFORM selects the data format. 47# Available formats represent essentially the same data, albeit 48# possibly with minor discrepancies that users are not likely to notice. 49# To get new features and the best data right away, use: 50# DATAFORM= vanguard 51# To wait a while before using new features, to give downstream users 52# time to upgrade zic (the default), use: 53# DATAFORM= main 54# To wait even longer for new features, use: 55# DATAFORM= rearguard 56# Rearguard users might also want "ZFLAGS = -b fat"; see below. 57DATAFORM= main 58 59# Change the line below for your timezone (after finding the one you want in 60# one of the $(TDATA) source files, or adding it to a source file). 61# Alternatively, if you discover you've got the wrong timezone, you can just 62# 'zic -l -' to remove it, or 'zic -l rightzone' to change it. 63# Use the command 64# make zonenames 65# to get a list of the values you can use for LOCALTIME. 66 67LOCALTIME= Factory 68 69 70# Installation locations. 71# 72# The defaults are suitable for Debian, except that if REDO is 73# posix_right or right_posix then files that Debian puts under 74# /usr/share/zoneinfo/posix and /usr/share/zoneinfo/right are instead 75# put under /usr/share/zoneinfo-posix and /usr/share/zoneinfo-leaps, 76# respectively.

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# 472# If you want to allocate state structures in localtime, add 473# -DALL_STATE 474# to the end of the "CFLAGS=" line.
