| |
| <p>Today's software market is a global one in which it is desirable to |
| develop and maintain one application (single source/single binary) that |
| supports a wide variety of languages. The International Components for |
| Unicode (C/C++) provides tools to help write platform-independent |
| applications that are internationalized and localized, with support |
| for:</p> |
| |
| <ul> |
| <li>Support for the latest version of the Unicode standard</li> |
| |
| <li>Character set conversions, with support for over 200 codepages</li> |
| |
| <li>Locale data for more than 220 locales</li> |
| |
| <li>Text collation (sorting) based on the Unicode Collation Algorithm |
| (=ISO 14651), customizable and tailored for national standards</li> |
| |
| <li>Transliteration services for script<->script transliterations |
| and general text operations</li> |
| |
| <li>Resource bundles for storing and accessing localized information</li> |
| |
| <li>Date/Number/Message formatting and parsing of culture-specific |
| input/output formats</li> |
| |
| <li>Text boundary analysis for finding characters, word and sentence |
| boundaries</li> |
| </ul> |
| |
| <p>ICU has a sister project <a href= |
| "http://oss.software.ibm.com/icu4j/">ICU4J</a> that extends the |
| internationalization capabilities of Java to a level similar to ICU. The |
| ICU C/C++ project is also called ICU4C when a distinction is necessary.</p> |

| <h2><a name="News" href="#News">What is new in this release?</a></h2> |
| |
| <p>The following list concentrates on <em>changes that affect existing |
| applications migrating from previous ICU releases</em>. For more news about |
| this release, see the <a href= |
| "http://oss.software.ibm.com/icu/download/2.2/">ICU 2.2 download |
| page</a>.</p> |
| |
| <h3>Support for Unicode 3.2</h3> |
| |
| <p>Unicode properties and algorithms have been upgraded to <a href= |
| "http://www.unicode.org/unicode/standard/versions/enumeratedversions.html#Unicode_3_2_0"> |
| Unicode 3.2</a>, which includes the addition of more than 1000 new encoded |
| characters. The UCA (<a href="http://www.unicode.org/reports/tr10/">Unicode |
| Collation Algorithm</a>) table is updated to the current version 3.1.1, |
| with Unicode 3.2-based canonical closure. All Unicode properties (except |
| for those in Unihan.txt) are now <a href= |
| "http://oss.software.ibm.com/cvs/icu/~checkout~/icuhtml/design/ucd_icu.html"> |
| available via direct APIs, and most via UnicodeSet</a>.</p> |
| |
| <h3><b>Additional and modified converters</b></h3> |
| |
| <p>New converter implementations are added for:</p> |
| |
| <ul> |
| <li>UTF-16 and UTF-32 (detect/emit BOM according to IANA |
| registration)<br> |
| These and related names used to be aliases for UTF16_PlatformEndian and |
| UTF32_PlatformEndian but are now separate, IANA-registration-compliant |
| converters that detect and emit the respective Byte Order Mark. The |
| "platform endian" converters (without automatic BOM handling) are now |
| only available via their specific names.</li> |
| |
| <li><a href="http://www.unicode.org/reports/tr26/">CESU-8</a> (while the |
| <a href="http://www.unicode.org/reports/tr28/#3_1_conformance">UTF-8 code |
| is tightened according to Unicode 3.2</a>)</li> |
| |
| <li><a href= |
| "http://oss.software.ibm.com/cvs/icu/~checkout~/icuhtml/design/conversion/bocu1/bocu1.html"> |
| BOCU-1</a> (MIME-compatible compression of Unicode text that preserves |
| binary order)</li> |
| </ul> |
| |
| <h3><b>Flexible data loading</b></h3> |
| |
| <p>ICU 2.2 has an extended search path functionality, more flexible data |
| override capabilities, and removes lesser-known heuristics for determining |
| the data path.</p> |
| |
| <ul> |
| <li>Performance: ICU will only load data from packages, not from single |
| files, when the search path is empty. This eliminates all file system |
| accesses after the packages (ICU data + application data) are loaded.<br> |
| If this is important, then an application should set the search path to |
| the empty path during initialization.</li> |
| |
| <li>Customizability: If the search path is not empty, then ICU searches |
| for single files before looking in packages, allowing to override/update |
| packaged data.</li> |
| |
| <li>User data: The new function ucnv_openPackage allows an application to |
| load an ICU character mapping table from its own data. This enables |
| applications to support more codepages than the ICU installation that it |
| uses.</li> |
| |
| <li>Separation between ICU data and user data: Single data files must now |
| always have a package name as prefix, which results in different file |
| names between ICU and all application packages even for the same locale |
| IDs etc.</li> |
| |
| <li>Multi-path: The search path can now contain multiple folders and can |
| list packages directly instead of just a single folder.</li> |
| |
| <li>Predictability: The search path can be set via the ICU_DATA |
| environment variable or via the u_setDataDirectory() function.<br> |
| ICU does not perform any other heuristics any more.</li> |
| </ul> |
| <b>Note:</b> while some of the old binary data may be still readable by ICU |
| 2.2 (resource bundles, for example), they need to be repackaged in order to |
| be used. |
| |
| <ul> |
| <li>If you have individual binary files, you have to rename them so that |
| you prepend a <code>'packagename_'</code>. Then use |
| <code>packagename</code> for opening.</li> |
| |
| <li>If you have a memory-mapped package file, you will need to unpack it |
| (use decmn tool), rename individual files as above (prepending the |
| package name), and repack the files.</li> |
| |
| <li>If you have a shared library file, you'll need to somehow get |
| individual files and repackage them.</li> |
| </ul> |
| |
| <h3><b>Customizable memory management</b></h3> |
| |
| <p>ICU 2.2 libraries do not use the global operators new and delete. |
| Instead, all C++ classes are derived from a common base class UObject which |
| implements new and delete operators for all of ICU's C++ classes. Users can |
| customize the ICU memory allocation by changing the functions in |
| source/common/cmemory.c that are used for non-class types and in UObject's |
| new and delete operators.</p> |
| |
| <p>This also means that ICU libraries may safely use a different heap than |
| the application because all memory is consistently allocated and released |
| from within the libraries. On Windows it is now possible to link the |
| application with, for example, the static C runtime library even though ICU |
| libraries use the DLL-based runtime.</p> |
| |
| <h3>Experimental locales moved to new repository</h3> |
| |
| <p>Experimental locales are ones for which we have incomplete data. Data |
| for such locales used to be included in the default ICU download, but have |
| been moved to a new <a href= |
| "http://oss.software.ibm.com/cvs/icu/locale/icu/experimental/">locale data |
| repository</a>, stored as another <a href= |
| "http://oss.software.ibm.com/icu/develop/cvs.html">ICU CVS module</a>. This |
| data can be added back into a customized ICU build, see the <a href= |
| "http://oss.software.ibm.com/icu/userguide/icudata.html">User Guide Data |
| chapter</a>. It can also still be viewed with the <a href= |
| "http://oss.software.ibm.com/icu/demo/">LocaleExplorer demo</a>.</p> |

| |
| <h2><a name="Download" href="#Download">How To Download the Source |
| Code</a></h2> |
| |
| <p>There are two ways to download ICU releases:</p> |
| |
| <ul> |
| <li><strong>Official Release Snapshot:</strong><br> |
| If you want to use ICU (as opposed to developing it), you should |
| download an official packaged version of the ICU source code. These |
| versions are tested more thoroughly than day-to-day development builds of |
| the system, and they are packaged in zip and tar files for convenient |
| download. These packaged files can be found at <a href= |
| "http://oss.software.ibm.com/icu/download/">http://oss.software.ibm.com/icu/download/</a>.<br> |
| |
| The packaged snapshots are named <strong>icu-nnnn.zip</strong> or |
| <strong>icu-nnnn.tgz</strong>, where nnnn is the version number. The .zip |
| file is used for Windows platforms, while the .tgz file is preferred on |
| most other platforms.<br> |
| Please unzip this file. It will reconstruct the source directory, which |
| includes anonymous CVS control directories (see below).</li> |
| |
| <li><strong>CVS Source Repository:</strong><br> |
| If you are interested in developing features, patches, or bug fixes for |
| ICU, you should probably be working with the latest version of the ICU |
| source code. You will need to check the code out of our CVS repository to |
| ensure that you have the most recent version of all of the files. See our |
| <a href="http://oss.software.ibm.com/icu/develop/cvs.html">CVS page</a> |
| for details.</li> |
| </ul> |
| |
| <h2><a name="SourceCode" href="#SourceCode">ICU Source Code |
| Organization</a></h2> |
| |
| <p>In the descriptions below, <strong><i><ICU></i></strong> is the |
| full path name of the icu directory (the top level directory from the |
| distribution archives) in your file system. You can also view the <a href= |
| "http://oss.software.ibm.com/icu/userguide/design.html">User's Guide</a> to |
| see which libraries you need for your software product. You need at least |
| the data (<code>[lib]icudt</code>) and the common (<code>[lib]icuuc</code>) |
| libraries in order to use ICU.</p> |

| <h3><a name="HowToBuildWindows" href="#HowToBuildWindows">How To Build And |
| Install On Windows</a></h3> |
| |
| <p>Building International Components for Unicode requires:</p> |
| |
| <ul> |
| <li>Microsoft NT 4.0 and above, or Windows 98 and above</li> |
| |
| <li>Microsoft Visual C++ 6.0 (Service Pack 2 is required to work with the |
| release build of max speed optimization).</li> |
| </ul> |
| |
| <p>(If you want to build with Microsoft Visual C++ .NET, please refer to |
| the <a href="#HowToBuildWindowsDotNet">note about building with Visual |
| Studio .NET</a> below.)</p> |
| |
| <p>The steps are:</p> |
| |
| <ol> |
| <li>Unzip the icu-XXXX.zip file into any convenient location. Using |
| command line zip, type "unzip -a icu-XXXX.zip -d drive:\directory", or |
| just use WinZip.</li> |
| |
| <li>Be sure that the ICU binary directory, <i><ICU></i>\bin\, is |
| included in the <strong>PATH</strong> environment variable. The tests |
| will not work without the location of the ICU dll files in the path.</li> |
| |
| <li>Set the <strong>TZ</strong> environment variable to |
| <strong>PST8PDT</strong>. The tests will not work in any other time |
| zone.</li> |
| |
| <li>Open the "<i><ICU></i>\source\allinone\allinone.dsw" workspace |
| file in Microsoft Visual C++ 6.0. (This workspace includes all the |
| International Components for Unicode libraries, necessary ICU building |
| tools, and the intltest and cintltest test suite projects). Please see |
| the note below if you want to build from the command line instead.</li> |
| |
| <li>Set the active Project to the "all" project. To do this: Choose |
| "Project" menu, and select "Set active project". In the submenu, select |
| the "all" workspace.</li> |
| |
| <li>Set the active configuration to "Win32 Debug" or "Win32 Release" (See |
| <a href="#HowToBuildWindowsConfig">note</a> below).</li> |
| |
| <li>Choose the "Build" menu and select "Rebuild All". If you want to |
| build the Debug and Release at the same time, see the <a href= |
| "#HowToBuildWindowsBatch">note</a> below.</li> |
| |
| <li>Run the C++ test suite, "intltest". To do this: set the active |
| project to "intltest", and press F5 to run it.</li> |
| |
| <li>Run the C test suite, "cintltst". To do this: set the active project |
| to "cintltst", and press F5 to run it.</li> |
| |
| <li>Make sure that both "cintltst" and "intltest" passed without any |
| errors. The return codes are non-zero when they do not pass. Visual C++ |
| will display the return codes in the debug tag of the output window. When |
| "intltest" and "cintltest" return 0, it means that everything is |
| installed correctly. You can press Ctrl+F5 on the test project to run the |
| test and see what error messages were displayed (if any tests |
| failed).</li> |
| |
| <li>Reset the <strong>TZ</strong> environment variable to its original |
| value, unless you plan on testing ICU any further.</li> |
| |
| <li>You are now able to develop applications with ICU by using the |
| libraries and tools in <i><ICU></i>\bin\. The headers are in |
| <i><ICU></i>\include\ and the link libraries are in |
| <i><ICU></i>\lib\. To install the ICU runtime on a machine, or ship |
| it with your application, copy the needed components from |
| <i><ICU></i>\bin\ to a location on the system PATH or to your |
| application directory.</li> |
| </ol> |
| |
| <p><a name="HowToBuildWindowsCommandLine"><strong>Using MSDEV At The |
| Command Line Note:</strong></a> You can build ICU from the command line. |
| Assuming that you have properly installed Microsoft Visual C++ to support |
| command line execution, you can run the following command, 'msdev |
| <i><ICU></i>\source\allinone\allinone.dsw /MAKE "ALL"'.</p> |
| |
| <p><a name="HowToBuildWindowsConfig"><strong>Setting Active Configuration |
| Note:</strong></a> To set the active configuration, two different |
| possibilities are:</p> |
| |
| <ul> |
| <li>Choose "Build" menu, select "Set Active Configuration", and select |
| "Win32 Release" or "Win32 Debug".</li> |
| |
| <li>Another way is to select "Customize" in the "Tools" menu, select the |
| "Toolbars" tab, enable "Build" instead of "Build Minibar", and click on |
| "Close". This will bring up a toolbar which you can move aside the other |
| permanent toolbars at the top of the MSVC window. The advantage is that |
| you now have an easy-to-reach pop-up menu that will always show the |
| currently selected active configuration. Or, you can drag the project and |
| configuration selections and drop them on the menu bar for later |
| selection.</li> |
| </ul> |
| |
| <p><a name="HowToBuildWindowsBatch"><strong>Batch Configuration |
| Note:</strong></a> If you want to build the Debug and Release |
| configurations at the same time, choose "Build" menu and select "Batch |
| Build..." instead (and mark all configurations as checked), then click the |
| button named "Rebuild All". The "all" workspace will build all the |
| libraries, test programs and various ICU tools (e.g. genrb for generating |
| binary locale data files).</p> |
| |
| <p><a name="HowToBuildWindowsDotNet"><strong>Microsoft Visual Studio .NET |
| Note:</strong></a> ICU will build with Microsoft Visual Studio .NET, though |
| this is not a supported platform at the time of this writing. Visual Studio |
| .NET will offer to convert the project files when you open the existing |
| workspace file. Choose "Yes to All" in the dialog asking whether to convert |
| the files or not (this creates new files) and then follow the rest of the |
| build instructions.</p> |

| <h3><a name="HowToBuildUnix" href="#HowToBuildUnix">How To Build And |
| Install On Unix</a></h3> |
| |
| <p>Building International Components for Unicode on Unix requires:</p> |
| |
| <ul> |
| <li>A C++ compiler installed on the target machine (for example: gcc, CC, |
| xlC_r, aCC, cxx, etc...).</li> |
| |
| <li>An ANSI C compiler installed on the target machine (for example: |
| cc).</li> |
| |
| <li>A recent version of GNU make (3.77+).</li> |
| |
| <li>For a list of z/OS tools please view the <a href= |
| "#HowToBuildZOS">z/OS build section</a> of this document for further |
| details.</li> |
| </ul> |
| |
| <p>Here are the steps to build ICU:</p> |
| |
| <ol> |
| <li>Decompress the icuXXXX.tar (or icuXXXX.tgz) file. For example, |
| <tt>gunzip -d < icuXXXX.tgz | tar xvf -</tt></li> |
| |
| <li>Change directory to the "icu/source".</li> |
| |
| <li>Run "chmod +x runConfigureICU configure install-sh" because these |
| files may have the wrong permissions.</li> |
| |
| <li>Run the <a href="source/runConfigureICU">runConfigureICU</a> script |
| for your platform. (See <a href="#HowToConfigureICU">note</a> |
| below).</li> |
| |
| <li>Type "gmake" (or "make" if GNU make is the default make on your |
| platform) to compile the libraries and all the data files. The proper |
| name of the GNU make command is printed at the end of the configuration |
| run, as in "You must use gmake to compile ICU".</li> |
| |
| <li>Optionally, type "gmake check" (or "make check") to run the test |
| suite, which checks for ICU's functionality integrity (See <a href= |
| "#HowToTestWithoutGmake">note</a> below).</li> |
| |
| <li>Type "gmake install" (or "make install") to install. The install |
| targets support the use of the DESTDIR variable to create the |
| installation tree under a specific destination directory. (See <a href= |
| "#HowToInstallICU">note</a> below).</li> |
| </ol> |
| |
| <p><a name="HowToConfigureICU"><strong>Configuring ICU NOTE:</strong></a> |
| Type "./runConfigureICU --help" for help on how to run it and a list of |
| supported platforms. You may also want to type "./configure --help" to |
| print the available configure options that you may want to give |
| runConfigureICU. If you are not using the runConfigureICU script, or your |
| platform is not supported by the script, you may need to set your CC,CXX, |
| CFLAGS and CXXFLAGS environment variables, and type "./configure". Some of |
| the more frequently used options to configure are --disable-64bit-libs to |
| create 32-bit libraries, and --srcdir to do out of source builds (build the |
| libraries in the current location).</p> |
| |
| <p><a name="HowToTestWithoutGmake"><strong>Running The Tests From The |
| Command Line NOTE:</strong></a> You may have to set certain variables if |
| you with to run test programs individually, that is apart from "make |
| check". The <strong>TZ</strong> environment variable needs to be set to |
| <strong>PST8PDT</strong>. Also, the environment variable |
| <strong>ICU_DATA</strong> can be set to the full pathname of the data |
| directory to indicate where the locale data files and conversion mapping |
| tables are when you are not using the shared library (e.g. by using the |
| .dat archive or the individual data files). The trailing "/" is required |
| after the directory name (e.g. "$Root/source/data/" will work, but the |
| value "$Root/source/data" is not acceptable). You do not need to set |
| <strong>ICU_DATA</strong> if the complete data library is in your library |
| path.</p> |
| |
| <p><a name="HowToInstallICU"><strong>Installing ICU NOTE:</strong></a> If |
| you are using the "gmake install" command, using the "--prefix" option on |
| configure or runConfigureICU will install ICU to the specified |
| location.</p> |
| |
| <p>Some platforms use package management tools to control the installation |
| and uninstallation of files on the system, as well as the integrity of the |
| system configuration. You may want to check if ICU can be packaged for your |
| package management tools by looking into the "packaging" directory. (Please |
| note that if you are using a snapshot of ICU from CVS, it is probable that |
| the packaging scripts or related files are not up to date with the contents |
| of ICU at this time, so use them with caution).</p> |
| |
| <h3><a name="HowToBuildZOS" href="#HowToBuildZOS">z/OS (os/390) |
| Platform</a></h3> |
| |
| <p>If you are building on the z/OS UNIX System Services platform, it is |
| important that you understand a few details:</p> |
| |
| <ul> |
| <li>APAR PQ58392 may be needed by z/OS 1.2 in order to get some ICU |
| number formatting functions to work properly.</li> |
| |
| <li>The gnu utilities gmake and gzip/gunzip are needed and can be |
| obtained for z/OS from <a href= |
| "http://www.ibm.com/servers/eserver/zseries/zos/unix/bpxa1ty1.html#opensrc"> |
| z/OS Unix - Tools and Toys</a>. Documentation on these tools can be found |
| at the <a href= |
| "http://publib-b.boulder.ibm.com/Redbooks.nsf/RedbookAbstracts/sg245944.html"> |
| Open Source Software for z/OS UNIX</a> Red Book.</li> |
| |
| <li>Encoding considerations: The source code assumes that it is compiled |
| with codepage ibm-1047 (to be exact, the UNIX System Services variant of |
| it). The pax command converts all of the source code files from ASCII to |
| codepage ibm-1047 (USS) EBCDIC. However, some files are binary files and |
| must not be converted, or must be converted back to their original state. |
| You can use the <a href="as_is/os390/unpax-icu.sh">unpax-icu.sh</a> |
| script to do this for you automatically. It will unpackage the tar file |
| and convert all the necessary files for you automatically.</li> |
| |
| <li> |
| <p>z/OS supports both native S/390 hexadecimal floating point and, |
| (with Version 2.6 and later) IEEE binary floating point. This is a |
| compile time option. Applications built with IEEE should use ICU dlls |
| that are built with IEEE (and vice versa). The environment variable |
| IEEE390=1 will cause the z/OS version of ICU to be built with IEEE |
| floating point. The default is native hexadecimal floating point.<br> |
| <em>Important:</em> Currently (ICU 1.4.2), native floating point |
| support is sufficient for codepage conversion, resource bundle and |
| UnicodeString operations, but the Format APIs, especially ChoiceFormat, |
| require IEEE binary floating point.</p> |
| |
| <p>Examples for configuring ICU:<br> |
| Debug build: <code>IEEE390=1 ./runConfigureICU --enable-debug |
| zOS/cxx</code><br> |
| Release build: <code>IEEE390=1 ./runConfigureICU zOS/cxx</code></p> |
| </li> |
| |
| <li>Since the default make on z/OS is not gmake, the pkgdata tool |
| requires that the "make" command is aliased to your installed version of |
| gmake. You may also need to set $MAKE equal to the fully-qualified path |
| of GNU make. GNU make is available with the "z/OS Unix - Tools and Toys" |
| that was mentioned above. The required version is the same Unix build |
| instructions.</li> |
| |
| <li>The makedep executable that is used with the z/OS ICU build process |
| is not shipped with ICU. It is available at the <a href= |
| "http://www.ibm.com/servers/eserver/zseries/zos/unix/bpxa1ty1.html#opensrc"> |
| z/OS Unix - Tools and Toys</a> site. The PATH environment variable should |
| be updated to contain the location of this executable prior to build. |
| Alternatively, makedep may be moved into an existing PATH directory.</li> |
| |
| <li>The rest of the instructions for building and testing ICU on z/OS |
| with Unix System Services are the same as the <a href= |
| "#HowToBuildUnix">How To Build And Install On Unix</a> section.</li> |
| </ul> |
| |
| <h4>z/OS Batch (PDS) support</h4> |
| |
| <p>By default, ICU builds its libraries into the HFS. In addition, there is |
| a z/OS specific environment variable to build some libraries into the z/OS |
| native file system. This is useful, for example, when your application is |
| externalized via Job Control Language (JCL).</p> |
| |
| <p>The OS390BATCH environment variable enables batch support. When |
| OS390BATCH is set, the libicuuc<i>XX</i>.dll, libicudt<i>XX</i>e.dll, and |
| libicudt<i>XX</i>e_stub.dll binaries are built into the native file system. |
| Turning on OS390BATCH does not turn off the normal HFS build. This means |
| that the HFS dlls will always be created.</p> |
| |
| <p>Two additional environment variables indicate the names of the z/OS data |
| sets to use. The LOADMOD environment variable identifies the name of the |
| data set that contains the dynamic link libraries (DLLs) and the LOADEXP |
| environment variable identifies the name of the data set that contains the |
| side decks, which are normally the files with the .x suffix in the HFS.</p> |
| |
| <p>Here is an example of some environment variables that you can set prior |
| to building ICU:</p> |
| <pre> |
| <samp>OS390BATCH=1 |
| LOADMOD=<i>USER</i>.ICU.LOAD |
| LOADEXP=<i>USER</i>.ICU.EXP</samp> |
| </pre> |
| |
| <p>The PDS member names are as follows:</p> |
| <pre> |
| <samp>IXMI<i>XX</i>UC --> libicuuc<i>XX</i>.dll |
| IXMI<i>XX</i>DA --> libicudt<i>XX</i>e.dll |
| IXMI<i>XX</i>D1 --> libicudt<i>XX</i>e_stub.dll <i>(When OS390_STUBDATA=1)</i></samp> |
| </pre> |
| |
| <p>You should point the LOADMOD environment variable at a partitioned data |
| set extended (PDS/E) and point the LOADEXP environment variable at a |
| partitioned data set (PDS). The PDS/E can be allocated with the following |
| attributes:</p> |
| <pre> |
| <samp>Data Set Name . . . : <i>USER</i>.ICU.LOAD |
| Management class. . : **None** |
| Storage class . . . : BASE |

| Platform</a></h3> |
| |
| <p>ICU Reference Release 2.2 contains partial support for the iSeries |

| <h2><a name="ImportantNotes" href="#ImportantNotes">Important Notes About |
| Using ICU</a></h2> |
| |
| <h3><a name="ImportantNotesCPlusPlus" href="#ImportantNotesCPlusPlus">Using |
| ICU in a Multithreaded Environment</a></h3> |
| |
| <p>If you are using ICU in a multithreaded application, there may be a |
| chance that the ICU global mutex is not initialized properly. Normally the |
| ICU global mutex is initialized during C++ static initialization, but there |
| are some compilers and linkers that do not properly perform C++ static |
| initialization in a library (this sometimes happens on HP/UX and on MacOS |
| X).</p> |
| |
| <p>Upon the first usage of most ICU APIs, the global mutex will get |
| initialized. For example, you could call uloc_countAvailable() or |
| uloc_getDefault() from your main() function before any threads are created. |
| Those functions will initialize the global mutex. Without one of these |
| function calls from a single thread, the data caches inside ICU may get |
| initialized more than once, which may cause memory leaks and other |
| problems. This problem normally does not happen when C++ static |
| initialization works properly.</p> |
| |
| <p>ICU does not use C++ static initialization for anything else, and |
| disabling threads in ICU will disable all C++ static initialization in |
| ICU.</p> |
| |
| <h3><a name="ImportantNotesBinaryCompat" href= |
| "#ImportantNotesBinaryCompat">Binary Compatibility</a></h3> |

| <p>Even though the ICU development team tries to make a stable API, some |
| breaking changes are required from time to time. ICU does not guarentee |
| binary compatibility of its functions or its data between releases. Please |
| view the <a href= |
| "http://oss.software.ibm.com/icu/userguide/design.html">ICU Design</a> |
| chapter of the User's Guide for details.</p> |

| <h3><a name="ImportantNotesWindows" href="#ImportantNotesWindows">Windows |
| Platform</a></h3> |
| |
| <p>If you are building on the Win32 platform, it is important that you |
| understand a few of the following build details.</p> |
| |
| <h4>DLL directories and the PATH setting</h4> |
| |
| <p>As delivered, the International Components for Unicode build as several |
| DLLs, which are placed in the "<i><ICU></i>\bin" directory. You must |
| add this directory to the PATH environment variable in your system, or any |
| executables you build will not be able to access International Components |
| for Unicode libraries. Alternatively, you can copy the DLL files into a |
| directory already in your PATH, but we do not recommend this. You can wind |
| up with multiple copies of the DLL and wind up using the wrong one.</p> |
| |
| <h4><a name="ImportantNotesWindowsPath">Changing your PATH</a></h4> |
| |
| <ul> |
| <li><strong>Windows 2000</strong>: Use the System Icon in the Control |
| Panel. Pick the "Advanced" tab. Select the "Environment Variables..." |
| button. Select the variable PATH in the lower box, and select the lower |
| "Edit..." button. In the "Variable Value" box, append the string |
| ";<i><ICU></i>\bin" to the end of the path string. If there is |
| nothing there, just type in "<i><ICU></i>\bin". Click the Set |
| button, then the OK button.</li> |
| |
| <li><strong>Windows NT</strong>: Use the System Icon in the Control |
| Panel. Pick the "Environment" tab, and select the variable PATH in the |
| lower box. In the "value" box, append the string |
| ";<i><ICU></i>\bin" at the end of the path string. If there is |
| nothing there, just type in "<i><ICU></i>\bin". Click the Set |
| button, then the OK button.</li> |
| |
| <li><strong>Windows 95/98/ME</strong>: Edit the autoexec.bat, and add the |
| following line to the end of file, "SET |
| PATH=%PATH%;<i><ICU></i>\bin"</li> |
| </ul> |
| |
| <p>Note: When packaging a Windows application for distribution and |
| installation on user systems, copies of the ICU DLLs should be included |
| with the application, and installed for exclusive use by the application. |
| This is the only way to insure that your app is running with the same |
| version of ICU, built with exactly the same options, that you developed and |
| tested with. Refer to Microsoft's guidelines on the usage of DLLs, or |
| search for the phrase "DLL hell" on <a href= |
| "http://msdn.microsoft.com/">msdn.microsoft.com</a>.</p> |
| |
| <h4>Linking with Runtime libraries</h4> |
| |
| <p>All the DLLs link with the C runtime library "Debug Multithreaded DLL" |
| or "Multithreaded DLL." (This is changed through the Project Settings |
| dialog, on the C/C++ tab, under Code Generation.) It is important that any |
| executable or other DLL you build which uses the International Components |
| for Unicode DLLs links with these runtime libraries as well. If you do not |
| do this, you will get random memory errors when you run the executable.<br> |
| </p> |
| |
| <h3><a name="ImportantNotesUnix" href="#ImportantNotesUnix">Unix Type |
| Platform</a></h3> |
| |
| <p>If you are building on a Unix platform, and if you are installing ICU in |
| a non-standard location, you may need to add the location of your ICU |
| libraries to your <strong>LD_LIBRARY_PATH</strong> or |
| <strong>LIBPATH</strong> environment variable (or the equivalent runtime |
| library path environment variable for your system). The ICU libraries may |
| not link or load properly without doing this.</p> |
| |
| <p>Note that if you do not want to have to set this variable, you may |
| instead use the --enable-rpath option at configuration time. This option |
| will instruct the linker to always look for the libraries where they are |
| installed. You will need to use the appropriate linker options when linking |
| your own applications and libraries against ICU, too. Please refer to your |
| system's linker manual for information about runtime paths. The use of |
| rpath also means that when building a new version of ICU you should not |
| have an older version installed in the same place as the new version's |
| installation directory, as the older libraries will used during the build, |
| instead of the new ones, likely leading to an incorrectly build ICU. (This |
| is the proper behavior of rpath.)</p> |
| |
| <h3><a name="ImportantNotesDefaultCP" href="#ImportantNotesDefaultCP">Using |
| the default codepage</a></h3> |
| |
| <p>ICU has code to determine the default codepage of the system or process. |
| This default codepage can be used to convert <code>char *</code> strings to |
| and from Unicode.</p> |
| |
| <p>Depending on system design, setup and APIs, it may not always be |
| possible to find a default codepage that fully works as expected. For |
| example,</p> |
| |
| <ul> |
| <li>On Windows there are three encodings in use at the same time. Unicode |
| (UTF-16) is always used inside of Windows, while for <code>char *</code> |
| encodings there are two classes, called "ANSI" and "OEM" codepages. ICU |
| will use the ANSI codepage. Note that the OEM codepage is used by default |
| for console window output.</li> |
| |
| <li>On some Unix-type systems, non-standard names are used for encodings, |
| or non-standard encodings are used altogether. Although ICU supports 200 |
| encodings in its standard build and many more aliases for them, it will |
| not be able to recognize such non-standard names.</li> |
| |
| <li>Some systems do not have a notion of a system or process codepage, |
| and may not have APIs for that.</li> |
| </ul> |
| |
| <p>If you have means of detecting a default codepage name that are more |
| appropriate for your application, then you should set that name with |
| <code>ucnv_setDefaultName()</code> as the first ICU function call. This |
| makes sure that the internally cached default converter will be |
| instantiated from your preferred name.</p> |
| |
| <p>Starting in ICU 2.0, when a converter for the default codepage cannot be |
| opened, a fallback default codepage name and converter will be used. On |
| most platforms, this will be US-ASCII. For z/OS (OS/390), ibm-1047-s390 is |
| the default fallback codepage. For AS/400 (iSeries), ibm-37 is the default |
| fallback codepage. This default fallback codepage is used when the |
| operating system is using a non-standard name for a default codepage, or |
| the converter was not packaged with ICU. The feature allows ICU to run in |
| unusual computing environments without completely failing.</p> |
| |
| <h3><a name="ImportantNotesDeprecatedAPI" href= |
| "#ImportantNotesDeprecatedAPI">Methods for enabling deprecated |
| APIs</a></h3> |
| |
| <h4>C</h4> |
| |
| <p>Some deprecated C APIs can be enabled without recompiling the ICU |
| libraries. This can be achieved by defining certain symbols before |
| including the ICU header files. For example, to enable deprecated C APIs |
| for formatting.</p> |
| <pre> |
| <samp>#ifndef U_USE_DEPRECATED_FORMAT_API |
| # define U_USE_DEPRECATED_FORMAT_API 1 |
| #endif |
| |
| #include "unicode/udat.h" |
| |
| int main(){ |
| UDateFormat *def, *fr, *fr_pat ; |
| UErrorCode status = U_ZERO_ERROR; |
| UChar temp[30]; |
| |
| fr = udat_open(UDAT_FULL, UDAT_DEFAULT, "fr_FR", NULL,0, &status); |
| if(U_FAILURE(status)){ |
| printf("Error creating the french dateformat using full time style\n %s\n", |
| myErrorName(status) ); |
| } |
| /* This is supposed to open default date format, |
| but later on it treats it like it is "en_US". |
| This is very bad when you try to run the tests |
| on a machine where the default locale is NOT "en_US" |
| */ |
| def = udat_open(UDAT_SHORT, UDAT_SHORT, "en_US", NULL, 0, &status); |
| if(U_FAILURE(status)){ |
| .... /* handle the error */ |
| } |
| }</samp> |
| </pre> |
| |
| <h4>C++</h4> |
| |
| <p>Deprecated C++ APIs cannot be enabled without recompiling ICU libraries. |
| Every service has a specific symbol that should be defined to enable the |
| deprecated API of that service. For example: To enable deprecated APIs in |
| transliteration service, the U_USE_DEPRECATED_TRANSLITERATOR_API symbol |
| should be defined before compiling ICU.</p> |
| |
| <h2><a name="PlatformDependencies" href="#PlatformDependencies">Platform |
| Dependencies</a></h2> |
| |
| <p>The platform dependencies have been mostly isolated into the following |
| files in the common library. This information can be useful if you are |
| porting ICU to a new platform.</p> |
| |
| <ul> |
| <li> |
| <strong>unicode/platform.h.in</strong> (autoconf'ed platforms)<br> |
| <strong>unicode/p<i>XXXX</i>.h</strong> (others: pwin32.h, pmacos.h, |
| ..): Platform-dependent typedefs and defines:<br> |
| <br> |
| |
| |
| <ul> |
| <li>XP_CPLUSPLUS for C++ only.</li> |
| |
| <li>TRUE and FALSE, UBool, int8_t, int16_t etc.</li> |
| |
| <li>U_EXPORT and U_IMPORT for specifying dynamic library import and |
| export</li> |
| </ul> |
| <br> |
| </li> |
| |
| <li> |
| <strong>unicode/putil.h, putil.c</strong>: platform-dependent |
| implementations of various functions that are platform dependent:<br> |
| <br> |
| |
| |
| <ul> |
| <li>uprv_isNaN, uprv_isInfinite, uprv_getNaN and uprv_getInfinity for |
| handling special floating point values.</li> |
| |
| <li>uprv_tzset, uprv_timezone, uprv_tzname and time for getting |
| platform specific time and time zone information.</li> |
| |
| <li>u_getDataDirectory for getting the default data directory.</li> |
| |
| <li>uprv_getDefaultLocaleID for getting the default locale |
| setting.</li> |
| |
| <li>uprv_getDefaultCodepage for getting the default codepage |
| encoding.</li> |
| </ul> |
| <br> |
| </li> |
| |
| <li> |
| <strong>umutex.h, umutex.c</strong>: Code for doing synchronization in |
| multithreaded applications. If you wish to use International Components |
| for Unicode in a multithreaded application, you must provide a |
| synchronization primitive that the classes can use to protect their |
| global data against simultaneous modifications. See Users' guide for |
| more information.<br> |
| <br> |
| |
| |
| <ul> |
| <li>We supply sample implementations for WinNT, Win95, Win98, |
| Sun/Solaris, RedHat/Linux, HP-UX and for AIX on an RS/6000.</li> |
| </ul> |
| <br> |
| </li> |
| |
| <li><strong>umapfile.h, umapfile.c</strong>: functions for mapping or |
| otherwise reading or loading files into memory. All access by ICU to data |
| from files makes use of these functions.<br> |
| <br> |
| </li> |
| |
| <li>For the intltest test suite, intltest.cpp in |
| "icu/source/test/intltest/" contains the method pathnameInContext, which |
| must also be adapted to any new platform.</li> |
| |
| <li>Using platform specific #ifdef macros are highly discouraged outside |
| of the scope of these files. When the source code gets updated in the |
| future, these #ifdef's can cause testing problems for your platform.</li> |
| </ul> |
| |
| <p>It is possible to build each library individually. They must be built in |
| the following order:<br> |
| </p> |
| |
| <ol> |
| <li>stubdata</li> |
| |
| <li>common</li> |
| |
| <li>i18n</li> |
| |
| <li>toolutil</li> |
| |
| <li>makeconv</li> |
| |
| <li>gencnval</li> |
| |
| <li>gennames</li> |
| |
| <li>gennorm</li> |
| |
| <li>genrb</li> |
| |
| <li>genbrk</li> |
| |
| <li>gentz</li> |
| |
| <li>genuca</li> |
| |
| <li>genccode</li> |
| |
| <li>gencmn</li> |
| |
| <li>pkgdata</li> |
| |
| <li>makedata (a project on Windows, or source/data/Makefile on Unix)</li> |
| |
| <li>ctestfw, intltest and cintltst, if you want to run the test |
| suite.</li> |
| |
| <li>uconv and ustdio can also be optionally built.</li> |
