| |
| <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 changes that affect existing |
| applications migrating from previous ICU releases. 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 3.1.1</h3> |
| |
| <p>ICU 2.0 has been upgraded to support <a href= |
| "http://www.unicode.org/unicode/standard/versions/Unicode3.1.1.html">Unicode |
| 3.1.1</a>, which includes the addition of 44,946 new encoded characters. |
| These characters cover several historic scripts, several sets of symbols, |
| and a very large collection of additional CJK ideographs.</p> |
| |
| <p>As part of this upgrade, a number of ICU services have been reviewed and |
| improved with regards to handling supplementary characters (surrogate |
| pairs). Especially, normalization is revamped for support of supplementary |
| characters and higher performance.</p> |
| |
| <p>ICU 2.1 also includes <a href= |
| "http://www.unicode.org/versions/corrigendum3.html">Corrigendum #3: U+F951 |
| Normalization</a>.</p> |
| |
| <h3>Memory and resource cleanup</h3> |
| |
| <p>ICU is carefully tested for memory leaks. Some memory is held in |
| internal caches that do not normally get released during normal operation. |
| These are not leaks because ICU continues to use them as necessary.</p> |
| |
| <p>For testing purposes (for memory leaks) and for a small number of |
| applications it can be useful to close all the memory that is allocated for |
| a library. ICU 2.0 supports this with a new function <code><a href= |
| "http://oss.software.ibm.com/icu/apiref/uclean_h.html">u_cleanup()</a></code> |
| that may be called after an application has released all ICU objects. |
| <code>u_cleanup()</code> will then release all of ICU's internal memory. |
| The ICU libraries can then even be unloaded cleanly without shutting down |
| the process.</p> |
| |
| <h3>Data loading changed</h3> |
| |
| <p>ICU data loading is simplified for most users. By default, the ICU build |
| creates a DLL/shared library that is linked directly with the common |
| library (<code>[lib]icuuc</code>). By placing all ICU libraries including |
| the data library into the same folder, ICU should start up and find its |
| data immediately. Dynamic loading of data from DLLs/shared libraries is not |
| supported any more.</p> |
| |
| <p>Before ICU 2.0, ICU did not itself link directly with its data library, |
| but some ICU applications did (like the Xerces XML parser) and called |
| <code>udata_setCommonData()</code>. This is not necessary any more in the |
| default case.<br> |
| On the other hand, this same technique can now be used to efficiently load |
| application data (e.g., for its own localization). An application can build |
| a data DLL/library of its own, link it, and call the new API |
| <code>udata_setAppData()</code>.</p> |
| |
| <p>For details on finding and loading ICU data and on options for portable, |
| common data files etc. see the <a href= |
| "http://oss.software.ibm.com/icu/userguide/icudata.html">User's Guide ICU |
| Data Chapter</a>.</p> |
| |
| <h3>Library linking changed</h3> |
| |
| <ul> |
| <li> |
| <b>Linkage improvement for HP/UX</b> |
| |
| <ul> |
| <li>The current directory (.) is now searched for libraries.</li> |
| |
| <li>Where available, $ORIGIN is set in the embedded path so that if |
| one ICU library is found, the system will be able to locate the |
| others.</li> |
| </ul> |
| </li> |
| |
| <li> |
| <b>Library Versioning for AIX (xlC and VisualAge)</b> |
| |
| <ul> |
| <li>AIX does not have facilities to enable library versioning. With |
| this patch, libraries will now be named for instance |
| <tt>libicuuc<b>20.1.so</b></tt> , however symlinks will allow |
| applications to still link using <tt>-licuuc</tt> (without the |
| benefit of versioning). To benefit from versioning, on AIX link |
| against the major and minor versions by using |
| <tt>-licuuc20</tt>.</li> |
| </ul> |
| </li> |
| |
| <li> |
| <b>Data Library Versioning for all platforms</b> |
| |
| <ul> |
| <li>The versioned name for the data library will be linked against by |
| the ICU libraries, that is, libicudt20b.so instead of |
| libicudata.so</li> |
| </ul> |
| </li> |
| </ul> |
| |
| <h3>Multithreaded usage is safer</h3> |
| |
| <p>It was discovered that some parts of ICU were not initialized in a |
| thread safe manner. This has been fixed.</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 (3.7+).</li> |
| |
| <li>For a list of OS/390 tools please view the <a href= |
| "#HowToBuildOS390">OS/390 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. 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="HowToBuildOS390" href="#HowToBuildOS390">OS/390 (zSeries) |
| Platform</a></h3> |
| |
| <p>If you are building on the OS/390 UNIX System Services platform, it is |
| important that you understand a few details:</p> |
| |
| <ul> |
| <li>The gnu utilities gmake and gzip/gunzip are needed and can be |
| obtained for OS/390 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 OS/390 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>OS/390 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 OS/390 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 OS/390 is not gmake, the pkgdata tool |
| requires that the "make" command is aliased to your installed version of |
| gmake.</li> |
| |
| <li>The makedep executable that is used with the OS/390 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> |
| To run all of the tests for ICU, use "gmake check". When running |
| individual tests of the test suite, the TZ environment variable should |
| be set to export TZ="PST8PDT" so that time zone comparisons are |
| correct. Building and testing ICU without using gmake requires that the |
| ICU libraries in the LIBPATH. In other words, the LIBPATH should |
| contain (each path prepended with the root directory that contains the |
| icu directory): |
| |
| <ul> |
| <li>icu/source/common</li> |
| |
| <li>icu/source/data</li> |
| |
| <li>icu/source/i18n</li> |
| |
| <li>icu/source/tools/ctestfw</li> |
| |
| <li>icu/source/tools/toolutil</li> |
| |
| <li>icu/source/extra/ustdio</li> |
| </ul> |
| </li> |
| </ul> |
| |
| <h4>OS/390 Batch (PDS) support</h4> |
| |
| <p>By default, ICU builds its libraries into the HFS. However, there is a |
| 390-specific switch to build some libraries into PDS files. The switch is |
| the environmental variable OS390BATCH, and if set, the following libraries |
| are built into PDS files: libicuuc<i>XX</i>.dll, libicudt<i>XX</i>e.dll, |
| libicudt<i>XX</i>e_390.dll, and libtestdata.dll. Turning on OS390BATCH does |
| not turn off the normal HFS build, thus the HFS dlls will always be |
| created.</p> |
| |
| <p>The names of the PDS files are determined by the value of the |
| environmental variables LOADMOD and LOADEXP. These variables must contain |
| the target PDS names whenever the OS390BATCH variable is set. LOADMOD is |
| the library (.dll) target dataset and LOADEXP is the side deck (.x) target |
| dataset.</p> |
| |
| <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_390.dll</samp> |
| </pre> |
| |
| <p>Example PDS attributes are as follows:</p> |
| <pre> |
| <samp>Data Set Name . . . : <i>USER</i>.ICU.LOAD |

| <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="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> 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 OS/390 (z/OS), 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>genrb</li> |
| |
| <li>gentz</li> |
| |
| <li>gennames</li> |
| |
| <li>genuca</li> |
| |
| <li>gennorm</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> |
