92
93 <p>Today's software market is a global one in which it is desirable to
94 develop and maintain one application (single source/single binary) that
95 supports a wide variety of languages. The International Components for
96 Unicode (ICU) libraries provide robust and full-featured Unicode services on
97 a wide variety of platforms to help this design goal. The ICU libraries
98 provide support for:</p>
99
100 <ul>
101 <li>The latest version of the Unicode standard</li>
102
103 <li>Character set conversions with support for over 220 codepages</li>
104
105 <li>Locale data for more than 250 locales</li>
106
107 <li>Language sensitive text collation (sorting) and searching based on the
108 Unicode Collation Algorithm (=ISO 14651)</li>
109
110 <li>Regular expression matching and Unicode sets</li>
111
112 <li>Transformations for normalization, upper/lowercase, script
113 transliterations (50+ pairs)</li>
114
115 <li>Resource bundles for storing and accessing localized information</li>
116
117 <li>Date/Number/Message formatting and parsing of culture specific
118 input/output formats</li>
119
120 <li>Calendar specific date and time manipulation</li>
121
122 <li>Complex text layout for Arabic, Hebrew, Indic and Thai</li>
123
124 <li>Text boundary analysis for finding characters, word and sentence
125 boundaries</li>
126 </ul>
127
128 <p>ICU has a sister project ICU4J that extends the internationalization
129 capabilities of Java to a level similar to ICU. The ICU C/C++ project is also
130 called ICU4C when a distinction is necessary.</p>

205 <h2><a name="News" href="#News" id="News">What is new in this
206 release?</a></h2>
207
208 <p>This is a maintenance release of ICU 4.8. No new APIs were added.</p>
209
210 <p>To see which APIs are new or changed in the 4.8 release, view the <a href="APIChangeReport.html">ICU4C API Change Report</a>. </p>
211
212 <p>The following list concentrates on <em>changes that affect existing
213 applications migrating from previous ICU releases</em>.
214 For more news about
215 this release, see the <a href="http://site.icu-project.org/download">ICU
216 download page</a>.</p>
217
218 <h3>MessageFormat Changes</h3>
219 <p>MessageFormat and related classes (choice/plural/select) have been reimplemented,
220 with several improvements and some incompatible changes.
221 See the <a href="http://site.icu-project.org/download/48">ICU 4.8 download</a> page for details.</p>
222
223 <h3>Unknown system time zone - Etc/Unknown</h3>
224 <p>The behavior of the time zone factory method TimeZone::createTimeZone(const UnicodeString&) has changed in this release.
225 When an unknown time zone ID is specified in the method, previous versions return a TimeZone instance
226 with ID "GMT" (offset 0 and no daylight saving time). In ICU 4.8, the method uses "Etc/Unknown" as the
227 time zone ID (but still offset 0 and no daylight saving time) for the case. Existing software checking
228 the returned time zone ID to validate the input ID may need to be updated to support the new behavior.</p>
229
230 <h2><a name="Download" href="#Download" id="Download">How To Download the
231 Source Code</a></h2>
232
233 <p>There are two ways to download ICU releases:</p>
234
235 <ul>
236 <li><strong>Official Release Snapshot:</strong><br />
237 If you want to use ICU (as opposed to developing it), you should download
238 an official packaged version of the ICU source code. These versions are
239 tested more thoroughly than day-to-day development builds of the system,
240 and they are packaged in zip and tar files for convenient download. These
241 packaged files can be found at <a href=
242 "http://site.icu-project.org/download">http://site.icu-project.org/download</a>.<br />
243 The packaged snapshots are named <strong>icu-nnnn.zip</strong> or
244 <strong>icu-nnnn.tgz</strong>, where nnnn is the version number. The .zip
245 file is used for Windows platforms, while the .tgz file is preferred on
246 most other platforms.<br />
247 Please unzip this file. </li>
248
249 <li><strong>Subversion Source Repository:</strong><br />
250 If you are interested in developing features, patches, or bug fixes for
251 ICU, you should probably be working with the latest version of the ICU
252 source code. You will need to check the code out of our Subversion repository to
253 ensure that you have the most recent version of all of the files. See our
254 <a href="http://site.icu-project.org/repository">source
255 repository</a> for details.</li>

266 your software product. You need at least the data (<code>[lib]icudt</code>)
267 and the common (<code>[lib]icuuc</code>) libraries in order to use ICU.</p>

511 <p>Depending on the platform and the type of installation,

513 <ul>
514 <li><b>Namespace:</b> By default, unicode/uversion.h has
515 "using namespace icu;" which defeats much of the purpose of the namespace.
516 (This is for historical reasons: Originally, ICU4C did not use namespaces,
517 and some compilers did not support them. The default "using" statement
518 preserves source code compatibility.)<br>
519 We recommend you turn this off via <code>-DU_USING_ICU_NAMESPACE=0</code>
520 or by modifying unicode/uversion.h:

536 ICU call sites then either qualify ICU types explicitly,

539 <li><b>Hardcode the default charset to UTF-8:</b> On platforms where
540 the default charset is always UTF-8,
541 like MacOS X and some Linux distributions,
542 we recommend hardcoding ICU's default charset to UTF-8.
543 This means that some implementation code becomes simpler and faster,
544 and statically linked ICU libraries become smaller.

562 <li><b>.dat file:</b> By default, the ICU data is built into
563 a shared library (DLL). This is convenient because it requires no
564 install-time or runtime configuration,
565 but the library is platform-specific and cannot be modified.
566 A .dat package file makes the opposite trade-off:
567 Platform-portable (except for endianness and charset family, which
568 can be changed with the icupkg tool)
569 and modifiable (also with the icupkg tool).
570 If a path is set, then single data files (e.g., .res files)
571 can be copied to that location to provide new locale data
572 or conversion tables etc.<br>
573 The only drawback with a .dat package file is that the application
574 needs to provide ICU with the file system path to the package file
575 (e.g., by calling <code>u_setDataDirectory()</code>)
576 or with a pointer to the data (<code>udata_setCommonData()</code>)
577 before other ICU API calls.
578 This is usually easy if ICU is used from an application where
579 <code>main()</code> takes care of such initialization.
580 It may be hard if ICU is shipped with
581 another shared library (such as the Xerces-C++ XML parser)
582 which does not control <code>main()</code>.<br>
583 See the <a href="http://userguide.icu-project.org/icudata">User Guide ICU Data</a>
584 chapter for more details.<br>
585 If possible, we recommend building the .dat package.
586 Specify <code>--with-data-packaging=archive</code>
587 on the configure command line, as in<br>
588 <code>runConfigureICU Linux --with-data-packaging=archive</code><br>
589 (Read the configure script's output for further instructions.
590 On Windows, the Visual Studio build generates both the .dat package
591 and the data DLL.)<br>
592 Be sure to install and use the tiny stubdata library
593 rather than the large data DLL.</li>
594 <li><b>Static libraries:</b> It may make sense to build the ICU code
595 into static libraries (.a) rather than shared libraries (.so/.dll).
596 Static linking reduces the overall size of the binary by removing
597 code that is never called.<br>
598 Example configure command line:<br>
599 <code>runConfigureICU Linux --enable-static --disable-shared</code></li>
600 <li><b>Out-of-source build:</b> It is usually desirable to keep the ICU
601 source file tree clean and have build output files written to
602 a different location. This is called an "out-of-source build".
603 Simply invoke the configure script from the target location:
604<pre>~/icu$ svn export http://source.icu-project.org/repos/icu/icu/trunk
605~/icu$ mkdir trunk-dev
606~/icu$ cd trunk-dev
607~/icu/trunk-dev$ ../trunk/source/runConfigureICU Linux
608~/icu/trunk-dev$ make check</pre></li>
609 </ul>
610 <h4>ICU as a System-Level Library</h4>
611 <p>If ICU is installed as a system-level library, there are further
612 opportunities and restrictions to consider.
613 For details, see the <em>Using ICU as an Operating System Level Library</em>
614 section of the <a href="http://userguide.icu-project.org/design">User Guide ICU Architectural Design</a> chapter.</p>
615 <ul>
616 <li><b>Data path:</b> For a system-level library, it is best to load
617 ICU data from the .dat package file because the file system path
618 to the .dat package file can be hardcoded. ICU will automatically set
619 the path to the final install location using U_ICU_DATA_DEFAULT_DIR.
620 Alternatively, you can set <code>-DICU_DATA_DIR=/path/to/icu/data</code>
621 when building the ICU code. (Used by source/common/putil.c.)<br>
622 Consider also setting <code>-DICU_NO_USER_DATA_OVERRIDE</code>
623 if you do not want the "ICU_DATA" environment variable to be used.
624 (An application can still override the data path via
625 <code>u_setDataDirectory()</code> or
626 <code>udata_setCommonData()</code>.</li>
627 <li><b>Hide draft API:</b> API marked with <code>@draft</code>
628 is new and not yet stable. Applications must not rely on unstable
629 APIs from a system-level library.
630 Define <code>U_HIDE_DRAFT_API</code>, <code>U_HIDE_INTERNAL_API</code>
631 and <code>U_HIDE_SYSTEM_API</code>
632 by modifying unicode/utypes.h before installing it.</li>
633 <li><b>Only C APIs:</b> Applications must not rely on C++ APIs from a
634 system-level library because binary C++ compatibility
635 across library and compiler versions is very hard to achieve.
636 Most ICU C++ APIs are in header files that contain a comment with
637 <code>\brief C++ API</code>.
638 Consider not installing these header files.</li>
639 <li><b>Disable renaming:</b> By default, ICU library entry point names
640 have an ICU version suffix. Turn this off for a system-level installation,
641 to enable upgrading ICU without breaking applications. For example:<br>
642 <code>runConfigureICU Linux --disable-renaming</code><br>
643 The public header files from this configuration must be installed
644 for applications to include and get the correct entry point names.</li>

659 </ul>
660
661 <p>The steps are:</p>
662
663 <ol>
664 <li>Unzip the icu-XXXX.zip file into any convenient location. Using command
665 line zip, type "unzip -a icu-XXXX.zip -d drive:\directory", or just use
666 WinZip.</li>
667
668 <li>Be sure that the ICU binary directory, <i><ICU></i>\bin\, is
669 included in the <strong>PATH</strong> environment variable. The tests will
670 not work without the location of the ICU DLL files in the path.</li>
671
672 <li>Open the "<i><ICU></i>\source\allinone\allinone.sln" workspace
673 file in Microsoft Visual Studio. (This solution includes all the
674 International Components for Unicode libraries, necessary ICU building
675 tools, and the test suite projects). Please see the <a href=
676 "#HowToBuildWindowsCommandLine">command line note below</a> if you want to
677 build from the command line instead.</li>
678
679 <li>Set the active platform to "Win32" or "x64" (See <a href="#HowToBuildWindowsPlatform">Windows platform note</a> below)
680 and configuration to "Debug" or "Release" (See <a href="#HowToBuildWindowsConfig">Windows configuration note</a> below).</li>

787 <li>Microsoft Windows</li>
788
789 <li>Microsoft Visual C++ (when gcc isn't used).</li>

808 <p>There are two ways you can build ICU with Cygwin. You can build with gcc
809 or Microsoft Visual C++. If you use gcc, the resulting libraries and tools
810 will depend on the Cygwin environment. If you use Microsoft Visual C++, the
811 resulting libraries and tools do not depend on Cygwin and can be more easily
812 distributed to other Windows computers (the generated man pages and shell
813 scripts still need Cygwin). To build with gcc, please follow the "<a href=
814 "#HowToBuildUNIX">How To Build And Install On UNIX</a>" instructions, while
815 you are inside a Cygwin bash shell. To build with Microsoft Visual C++,
816 please use the following instructions:</p>
817
818 <ol>
819 <li>Start the Windows "Command Prompt" window. This is different from the
820 gcc build, which requires the Cygwin Bash command prompt. The Microsoft
821 Visual C++ compiler will not work with a bash command prompt.</li>
822
823 <li>If the computer isn't set up to use Visual C++ from the command line,
824 you need to run vcvars32.bat.<br>For example:<br>"<tt>C:\Program Files\Microsoft

977 <h3><a name="HowToBuildZOS" href="#HowToBuildZOS" id="HowToBuildZOS">How To
978 Build And Install On z/OS (OS/390)</a></h3>
979
980 <p>You can install ICU on z/OS or OS/390 (the previous name of z/OS), but IBM
981 tests only the z/OS installation. You install ICU in a z/OS UNIX system
982 services file system such as HFS or zFS. On this platform, it is important
983 that you understand a few details:</p>
984
985 <ul>
986 <li>The makedep and GNU make tools are required for building ICU. If it
987 is not already installed on your system, it is available at the <a href=
988 "http://www-03.ibm.com/servers/eserver/zseries/zos/unix/bpxa1toy.html">z/OS UNIX -
989 Tools and Toys</a> site. The PATH environment variable should be updated to
990 contain the location of this executable prior to build. Failure to add these
991 tools to your PATH will cause ICU build failures or cause pkgdata to fail
992 to run.</li>
993
994 <li>Since USS does not support using the mmap() function over NFS, it is
995 recommended that you build ICU on a local filesystem. Once ICU has been
996 built, you should not have this problem while using ICU when the data
997 library has been built as a shared library, which is this is the default
998 setting.</li>
999
1000 <li>Encoding considerations: The source code assumes that it is compiled
1001 with codepage ibm-1047 (to be exact, the UNIX System Services variant of
1002 it). The pax command converts all of the source code files from ASCII to
1003 codepage ibm-1047 (USS) EBCDIC. However, some files are binary files and
1004 must not be converted, or must be converted back to their original state.
1005 You can use the <a href="as_is/os390/unpax-icu.sh">unpax-icu.sh</a> script
1006 to do this for you automatically. It will unpackage the tar file and
1007 convert all the necessary files for you automatically.</li>
1008
1009 <li>z/OS supports both native S/390 hexadecimal floating point and (with
1010 OS/390 2.6 and later) IEEE 754 binary floating point. This is a compile
1011 time option. Applications built with IEEE should use ICU DLLs that are
1012 built with IEEE (and vice versa). The environment variable IEEE390=0 will
1013 cause the z/OS version of ICU to be built without IEEE floating point
1014 support and use the native hexadecimal floating point. By default ICU is
1015 built with IEEE 754 support. Native floating point support is sufficient
1016 for codepage conversion, resource bundle and UnicodeString operations, but
1017 the Format APIs require IEEE binary floating point.</li>
1018
1019 <li>z/OS introduced the concept of Extra Performance Linkage (XPLINK) to
1020 bring performance improvement opportunities to call-intensive C and C++
1021 applications such as ICU. XPLINK is enabled on a DLL-by-DLL basis, so if
1022 you are considering using XPLINK in your application that uses ICU, you
1023 should consider building the XPLINK-enabled version of ICU. You need to
1024 set ICU's environment variable <code>OS390_XPLINK=1</code> prior to
1025 invoking the make process to produce binaries that are enabled for
1026 XPLINK. The XPLINK option, which is available for z/OS 1.2 and later,
1027 requires the PTF PQ69418 to build XPLINK enabled binaries.</li>
1028
1029 <li>Currently in ICU 3.0, there is an issue with building on z/OS without
1030 XPLINK and with the C++ iostream. By default, the iostream library on z/OS
1031 is XPLINK enabled. If you are not building an XPLINK enabled version of
1032 ICU, you should use the <code>--with-iostream=old</code> configure option
1033 when using runConfigureICU. This will prevent applications that use the
1034 icuio library from crashing.</li>
1035
1036 <li>Also note that on current versions of z/OS, the <a href='http://www-01.ibm.com/support/docview.wss?uid=swg21202407&wv=1'>XPLINK version (C128) of the
1037 C++ standard library is standard.</a> Therefore you may see an error when running
1038 with XPLINK disabled. To avoid this error, set the following environment variable or similar:
1039 <pre><a href='http://www-01.ibm.com/support/docview.wss?uid=swg21376279'>export _CXX_PSYSIX="CEE.SCEELIB(C128N)":"CBC.SCLBSID(IOSTREAM,COMPLEX)"</a></pre>
1040 </li>
1041
1042
1043 <li>The rest of the instructions for building and testing ICU on z/OS with
1044 UNIX System Services are the same as the <a href="#HowToBuildUNIX">How To
1045 Build And Install On UNIX</a> section.</li>
1046 </ul>
1047
1048 <h4>z/OS (Batch/PDS) support outside the UNIX system services
1049 environment</h4>
1050
1051 <p>By default, ICU builds its libraries into the UNIX file system (HFS). In
1052 addition, there is a z/OS specific environment variable (OS390BATCH) to build
1053 some libraries into the z/OS native file system. This is useful, for example,
1054 when your application is externalized via Job Control Language (JCL).</p>
1055
1056 <p>The OS390BATCH environment variable enables non-UNIX support including the
1057 batch environment. When OS390BATCH is set, the libicui18n<i>XX</i>.dll,
1058 libicuuc<i>XX</i>.dll, and libicudt<i>XX</i>e.dll binaries are built into
1059 data sets (the native file system). Turning on OS390BATCH does not turn off
1060 the normal z/OS UNIX build. This means that the z/OS UNIX (HFS) DLLs will
1061 always be created.</p>
1062
1063 <p>Two additional environment variables indicate the names of the z/OS data
1064 sets to use. The LOADMOD environment variable identifies the name of the data
1065 set that contains the dynamic link libraries (DLLs) and the LOADEXP
1066 environment variable identifies the name of the data set that contains the
1067 side decks, which are normally the files with the .x suffix in the UNIX file
1068 system.</p>
1069
1070 <p>A data set is roughly equivalent to a UNIX or Windows file. For most kinds
1071 of data sets the operating system maintains record boundaries. UNIX and
1072 Windows files are byte streams. Two kinds of data sets are PDS and PDSE. Each
1073 data set of these two types contains a directory. It is like a UNIX
1074 directory. Each "file" is called a "member". Each member name is limited to
1075 eight bytes, normally EBCDIC.</p>
1076
1077 <p>Here is an example of some environment variables that you can set prior to
1078 building ICU:</p>
1079<pre>
1080<samp>OS390BATCH=1
1081LOADMOD=<i>USER</i>.ICU.LOAD
1082LOADEXP=<i>USER</i>.ICU.EXP</samp>
1083</pre>
1084
1085 <p>The PDS member names for the DLL file names are as follows:</p>
1086<pre>
1087<samp>IXMI<i>XX</i>IN --> libicui18n<i>XX</i>.dll
1088IXMI<i>XX</i>UC --> libicuuc<i>XX</i>.dll
1089IXMI<i>XX</i>DA --> libicudt<i>XX</i>e.dll</samp>
1090</pre>
1091
1092 <p>You should point the LOADMOD environment variable at a partitioned data
1093 set extended (PDSE) and point the LOADEXP environment variable at a
1094 partitioned data set (PDS). The PDSE can be allocated with the following
1095 attributes:</p>

1197 <h3><a name="HowToCrossCompileICU" href="#HowToCrossCompileICU" id="HowToCrossCompileICU">How To Cross Compile ICU</a></h3>
1198 <p>This section will explain how to build ICU on one platform, but to produce binaries intended to run on another. This is commonly known as a cross compile.</p>
1199 <p>Normally, in the course of a build, ICU needs to run the tools that it builds in order to generate and package data and test-data.In a cross compilation setting, ICU is built on a different system from that which it eventually runs on. An example might be, if you are building for a small/headless system (such as an embedded device), or a system where you can't easily run the ICU command line tools (any non-UNIX-like system).</p>
1200 <p>To reduce confusion, we will here refer to the "A" and the "B" system.System "A" is the actual system we will be running on- the only requirements on it is are it is able to build ICU from the command line targetting itself (with configure or runConfigureICU), and secondly, that it also contain the correct toolchain for compiling and linking for the resultant platform, referred to as the "B" system.</p>
1201 <p>The autoconf docs use the term "build" for A, and "host" for B. More details at: <a href="http://www.gnu.org/software/autoconf/manual/html_node/Specifying-Names.html#Specifying-Names">http://www.gnu.org/software/autoconf/manual/html_node/Specifying-Names.html</a></p>

1236 <h2><a name="HowToPackage" href="#HowToPackage" id="HowToPackage">How To
1237 Package ICU</a></h2>
1238
1239 <p>There are many ways that a person can package ICU with their software
1240 products. Usually only the libraries need to be considered for packaging.</p>
1241
1242 <p>On UNIX, you should use "<tt>gmake install</tt>" to make it easier to
1243 develop and package ICU. The bin, lib and include directories are needed to
1244 develop applications that use ICU. These directories will be created relative
1245 to the "<tt>--prefix=</tt><i>dir</i>" configure option (See the <a href=
1246 "#HowToBuildUNIX">UNIX build instructions</a>). When ICU is built on Windows,
1247 a similar directory structure is built.</p>
1248
1249 <p>When changes have been made to the standard ICU distribution, it is
1250 recommended that at least one of the following guidelines be followed for
1251 special packaging.</p>
1252
1253 <ol>
1254 <li>Add a suffix name to the library names. This can be done with the
1255 --with-library-suffix configure option.</li>
1256
1257 <li>The installation script should install the ICU libraries into the
1258 application's directory.</li>
1259 </ol>
1260
1261 <p>Following these guidelines prevents other applications that use a standard
1262 ICU distribution from conflicting with any libraries that you need. On
1263 operating systems that do not have a standard C++ ABI (name mangling) for
1264 compilers, it is recommended to do this special packaging anyway. More
1265 details on customizing ICU are available in the <a href=
1266 "http://userguide.icu-project.org/">User's Guide</a>. The <a href=
1267 "#SourceCode">ICU Source Code Organization</a> section of this readme.html

1363
1364 <p>Normally only the above ICU libraries need to be considered for packaging.
1365 The versionless symbolic links to these libraries are only needed for easier
1366 development. The <i>X</i>, <i>Y</i> and <i>Z</i> parts of the name are the
1367 version numbers of ICU. For example, ICU 2.0.2 would have the name
1368 libicuuc.so.20.2 for the common library. The exact format of the library
1369 names can vary between platforms due to how each platform can handles library
1370 versioning.</p>

1375 <h3><a name="ImportantNotesMultithreaded" href="#ImportantNotesMultithreaded"
1376 id="ImportantNotesMultithreaded">Using ICU in a Multithreaded
1377 Environment</a></h3>
1378
1379 <p>Some versions of ICU require calling the <code>u_init()</code> function
1380 from <code>uclean.h</code> to ensure that ICU is initialized properly. In
1381 those ICU versions, <code>u_init()</code> must be called before ICU is used
1382 from multiple threads. There is no harm in calling <code>u_init()</code> in a
1383 single-threaded application, on a single-CPU machine, or in other cases where
1384 <code>u_init()</code> is not required.</p>
1385
1386 <p>In addition to ensuring thread safety, <code>u_init()</code> also attempts
1387 to load at least one ICU data file. Assuming that all data files are packaged
1388 together (or are in the same folder in files mode), a failure code from
1389 <code>u_init()</code> usually means that the data cannot be found. In this
1390 case, the data may not be installed properly, or the application may have
1391 failed to call <code>udata_setCommonData()</code> or
1392 <code>u_setDataDirectory()</code> which specify to ICU where it can find its
1393 data.</p>
1394
1395 <p>Since <code>u_init()</code> will load only one or two data files, it
1396 cannot guarantee that all of the data that an application needs is available.
1397 It cannot check for all data files because the set of files is customizable,
1398 and some ICU services work without loading any data at all. An application
1399 should always check for error codes when opening ICU service objects (using
1400 <code>ucnv_open()</code>, <code>ucol_open()</code>, C++ constructors,
1401 etc.).</p>
1402
1403 <h4>ICU 3.4 and later</h4>
1404
1405 <p>ICU 3.4 self-initializes properly for multi-threaded use. It achieves this
1406 without performance penalty by hardcoding the core Unicode properties data,
1407 at the cost of some flexibility. (For details see Jitterbug 4497.)</p>
1408
1409 <p><code>u_init()</code> can be used to check for data loading. It tries to
1410 load the converter alias table (<code>cnvalias.icu</code>).</p>
1411
1412 <h4>ICU 2.6..3.2</h4>
1413
1414 <p>These ICU versions require a call to <code>u_init()</code> before
1415 multi-threaded use. The services that are directly affected are those that
1416 don't have a service object and need to be fast: normalization and character
1417 properties.</p>
1418
1419 <p><code>u_init()</code> loads and initializes the data files for
1420 normalization and character properties (<code>unorm.icu</code> and
1421 <code>uprops.icu</code>) and can therefore also be used to check for data
1422 loading.</p>
1423
1424 <h4>ICU 2.4 and earlier</h4>
1425
1426 <p>ICU 2.4 and earlier versions were not prepared for multithreaded use on
1427 multi-CPU platforms where the CPUs implement weak memory coherency. These
1428 CPUs include: Power4, Power5, Alpha, Itanium. <code>u_init()</code> was not
1429 defined yet.</p>

1432 "ImportantNotesHPUX">Using ICU in a Multithreaded Environment on
1433 HP-UX</a></h4>
1434
1435 <p>If you are building ICU with a newer aCC compiler and you are planning on
1436 using the older <iostream.h> instead of the newer <iostream>, you
1437 will need to use a special configure flag before building ICU. By default,
1438 the aCC <a href="http://docs.hp.com/en/1405/options.htm#optioncap-AA">-AA</a>
1439 flag is used on HP-UX when the compiler supports that option in order to make
1440 ICU thread safe with RogueWave and other libraries using the 2.0 Standard C++
1441 library. Your applications that use ICU will also need to use the <a href=
1442 "http://docs.hp.com/en/1405/options.htm#optioncap-AA">-AA</a> compiler flag.
1443 To turn off this behavior in ICU, you will need to use the --with-iostream=old
1444 configure option when you first use runConfigureICU.</p>

1474 <h3><a name="ImportantNotesWindows" href="#ImportantNotesWindows" id=
1475 "ImportantNotesWindows">Windows Platform</a></h3>
1476
1477 <p>If you are building on the Win32 platform, it is important that you
1478 understand a few of the following build details.</p>
1479
1480 <h4>DLL directories and the PATH setting</h4>
1481
1482 <p>As delivered, the International Components for Unicode build as several
1483 DLLs, which are placed in the "<i><ICU></i>\bin" directory. You must
1484 add this directory to the PATH environment variable in your system, or any
1485 executables you build will not be able to access International Components for
1486 Unicode libraries. Alternatively, you can copy the DLL files into a directory
1487 already in your PATH, but we do not recommend this. You can wind up with
1488 multiple copies of the DLL and wind up using the wrong one.</p>
1489
1490 <h4><a name="ImportantNotesWindowsPath" id=
1491 "ImportantNotesWindowsPath">Changing your PATH</a></h4>
1492
1493 <p><strong>Windows 2000/XP</strong>: Use the System Icon in the Control
1494 Panel. Pick the "Advanced" tab. Select the "Environment Variables..."
1495 button. Select the variable PATH in the lower box, and select the lower
1496 "Edit..." button. In the "Variable Value" box, append the string
1497 ";<i><ICU></i>\bin" to the end of the path string. If there is
1498 nothing there, just type in "<i><ICU></i>\bin". Click the Set button,
1499 then the OK button.</p>
1500
1501 <p>Note: When packaging a Windows application for distribution and
1502 installation on user systems, copies of the ICU DLLs should be included with
1503 the application, and installed for exclusive use by the application. This is
1504 the only way to insure that your application is running with the same version
1505 of ICU, built with exactly the same options, that you developed and tested
1506 with. Refer to Microsoft's guidelines on the usage of DLLs, or search for the
1507 phrase "DLL hell" on <a href=
1508 "http://msdn.microsoft.com/">msdn.microsoft.com</a>.</p>
1509
1510 <h3><a name="ImportantNotesUNIX" href="#ImportantNotesUNIX" id=
1511 "ImportantNotesUNIX">UNIX Type Platform</a></h3>
1512
1513 <p>If you are building on a UNIX platform, and if you are installing ICU in a
1514 non-standard location, you may need to add the location of your ICU libraries
1515 to your <strong>LD_LIBRARY_PATH</strong> or <strong>LIBPATH</strong>
1516 environment variable (or the equivalent runtime library path environment
1517 variable for your system). The ICU libraries may not link or load properly
1518 without doing this.</p>
1519
1520 <p>Note that if you do not want to have to set this variable, you may instead
1521 use the --enable-rpath option at configuration time. This option will
1522 instruct the linker to always look for the libraries where they are
1523 installed. You will need to use the appropriate linker options when linking
1524 your own applications and libraries against ICU, too. Please refer to your
1525 system's linker manual for information about runtime paths. The use of rpath
1526 also means that when building a new version of ICU you should not have an
1527 older version installed in the same place as the new version's installation
1528 directory, as the older libraries will used during the build, instead of the
1529 new ones, likely leading to an incorrectly build ICU. This is the proper
1530 behavior of rpath.</p>

1535 <h3><a name="PlatformDependenciesNew" href="#PlatformDependenciesNew" id=
1536 "PlatformDependenciesNew">Porting To A New Platform</a></h3>
1537
1538 <p>If you are using ICU's Makefiles to build ICU on a new platform, there are
1539 a few places where you will need to add or modify some files. If you need
1540 more help, you can always ask the <a href=
1541 "http://site.icu-project.org/contacts">icu-support mailing list</a>. Once
1542 you have finished porting ICU to a new platform, it is recommended that you
1543 contribute your changes back to ICU via the icu-support mailing list. This
1544 will make it easier for everyone to benefit from your work.</p>
1545
1546 <h4>Data For a New Platform</h4>
1547
1548 <p>For some people, it may not be necessary for completely build ICU. Most of
1549 the makefiles and build targets are for tools that are used for building
1550 ICU's data, and an application's data (when an application uses ICU resource
1551 bundles for its data).</p>
1552
1553 <p>Data files can be built on a different platform when both platforms share
1554 the same endianness and the same charset family. This assertion does not
1555 include platform dependent DLLs/shared/static libraries. For details see the
1556 User Guide <a href="http://userguide.icu-project.org/icudata">ICU
1557 Data</a> chapter.</p>
1558
1559 <p>ICU 3.6 removes the requirement that ICU be completely built in the native
1560 operating environment. It adds the icupkg tool which can be run on any
1561 platform to turn binary ICU data files from any one of the three formats into
1562 any one of the other data formats. This allows a application to use ICU data
1563 built anywhere to be used for any other target platform.</p>
1564
1565 <p><strong>WARNING!</strong> Building ICU without running the tests is not
1566 recommended. The tests verify that ICU is safe to use. It is recommended that
1567 you try to completely port and test ICU before using the libraries for your
1568 own application.</p>
1569
1570 <h4>Adapting Makefiles For a New Platform</h4>
1571
1572 <p>Try to follow the build steps from the <a href="#HowToBuildUNIX">UNIX</a>
1573 build instructions. If the configure script fails, then you will need to
1574 modify some files. Here are the usual steps for porting to a new
1575 platform:<br />
1576 </p>
1577
1578 <ol>
1579 <li>Create an mh file in icu/source/config/. You can use mh-linux or a
1580 similar mh file as your base configuration.</li>
1581
1582 <li>Modify icu/source/aclocal.m4 to recognize your platform's mh file.</li>
1583
1584 <li>Modify icu/source/configure.in to properly set your <b>platform</b> C
1585 Macro define.</li>
1586
1587 <li>Run <a href="http://www.gnu.org/software/autoconf/">autoconf</a> in
1588 icu/source/ without any options. The autoconf tool is standard on most
1589 Linux systems.</li>
1590
1591 <li>If you have any optimization options that you want to normally use, you
1592 can modify icu/source/runConfigureICU to specify those options for your
1593 platform.</li>
1594
1595 <li>Build and test ICU on your platform. It is very important that you run
1596 the tests. If you don't run the tests, there is no guarentee that you have
1597 properly ported ICU.</li>
1598 </ol>

1600 <h3><a name="PlatformDependenciesImpl" href="#PlatformDependenciesImpl" id=
1601 "PlatformDependenciesImpl">Platform Dependent Implementations</a></h3>
1602
1603 <p>The platform dependencies have been mostly isolated into the following
1604 files in the common library. This information can be useful if you are
1605 porting ICU to a new platform.</p>
1606
1607 <ul>
1608 <li>
1609 <strong>unicode/platform.h.in</strong> (autoconf'ed platforms)<br />
1610 <strong>unicode/p<i>XXXX</i>.h</strong> (others: pwin32.h, ppalmos.h,
1611 ..): Platform-dependent typedefs and defines:<br />
1612 <br />
1613
1614
1615 <ul>
1616 <li>Generic types like UBool, int8_t, int16_t, int32_t, int64_t,
1617 uint64_t etc.</li>
1618
1619 <li>U_EXPORT and U_IMPORT for specifying dynamic library import and
1620 export</li>
1621
1622 <li><iostream> usability</li>
1623
1624 <li>Thread safety usability</li>
1625 </ul>
1626 <br />
1627 </li>
1628
1629 <li>
1630 <strong>unicode/putil.h, putil.c</strong>: platform-dependent
1631 implementations of various functions that are platform dependent:<br />
1632 <br />
1633
1634
1635 <ul>
1636 <li>uprv_isNaN, uprv_isInfinite, uprv_getNaN and uprv_getInfinity for
1637 handling special floating point values.</li>
1638
1639 <li>uprv_tzset, uprv_timezone, uprv_tzname and time for getting
1640 platform specific time and time zone information.</li>
1641
1642 <li>u_getDataDirectory for getting the default data directory.</li>
1643
1644 <li>uprv_getDefaultLocaleID for getting the default locale
1645 setting.</li>
1646
1647 <li>uprv_getDefaultCodepage for getting the default codepage
1648 encoding.</li>
1649 </ul>
1650 <br />
1651 </li>
1652
1653 <li>
1654 <strong>umutex.h, umutex.c</strong>: Code for doing synchronization in
1655 multithreaded applications. If you wish to use International Components
1656 for Unicode in a multithreaded application, you must provide a
1657 synchronization primitive that the classes can use to protect their
1658 global data against simultaneous modifications. We already supply working
1659 implementations for many platforms that ICU builds on.<br />
1660 <br />
1661 </li>
1662
1663 <li><strong>umapfile.h, umapfile.c</strong>: functions for mapping or
1664 otherwise reading or loading files into memory. All access by ICU to data
1665 from files makes use of these functions.<br />
1666 <br />
1667 </li>
1668
1669 <li>Using platform specific #ifdef macros are highly discouraged outside of
1670 the scope of these files. When the source code gets updated in the future,
1671 these #ifdef's can cause testing problems for your platform.</li>
