<h2><a name="Introduction" href="#Introduction">Introduction</a></h2>
|
|
|
|
<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 (ICU) libraries provide robust and full-featured Unicode services
|
|
on a wide variety of platforms to help this design goal. The ICU libraries
|
|
provide support for:</p>
|
|
|
|
<ul>
|
|
<li>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 230 locales</li>
|
|
|
|
<li>Language sensitive text collation (sorting) and searching based on
|
|
the Unicode Collation Algorithm (=ISO 14651)</li>
|
|
|
|
<li>Regular expression matching and Unicode sets</li>
|
|
|
|
<li>Transformations for normalization, upper/lowercase, script
|
|
transliterations (50+ pairs)</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>Calendar specific date and time manipulation</li>
|
|
|
|
<li>Complex text layout for Arabic, Hebrew, Indic and Thai</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/2.6/">ICU 2.6 download
|
|
page</a>.</p>
|
|
|
|
<h3>ICU code library size</h3>
|
|
|
|
<p>ICU code libraries can be made smaller by removing functionality. See <a
|
|
href="#MakeICUSmaller">How to Make ICU Smaller</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>Flexible data loading</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>
|
|
|
|
<p><strong>Note:</strong> 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.</p>
|
|
|
|
<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>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>

<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>

|
below).</li>
|
|
|
|
<li>Type <tt>"gmake"</tt> (or "make" if GNU make is the default make on

|
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">How To Build And Install
|
|
On z/OS (OS/390)</a></h3>
|
|
|
|
<p>You can install ICU on z/OS or OS/390 (the previous name of z/OS), but
|
|
IBM tests only the z/OS installation. These platforms commonly are called
|
|
"MVS". You install ICU in a z/OS UNIX system services file system such as
|
|
HFS or zFS. On this platform, it is important that you understand a few
|
|
details:</p>
|
|
|
|
<ul>
|
|
<li>APAR PQ58392 may be needed by z/OS 1.2 or 1.3 in order to get some
|
|
ICU number formatting functions to work properly. The APAR affects C and
|
|
C++ code.</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.

|
|
<p>z/OS supports both native S/390 hexadecimal floating point and,
|
|
(with OS/390 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</code><br>
|
|
Release build: <code>IEEE390=1 ./runConfigureICU zOS</code></p>
|
|
</li>
|
|
|
|
<li>
|
|
<p>z/OS introduced the concept of Extra Performance Linkage (XPLINK) to
|
|
bring performance improvement opportunities to call-intensive C and C++
|
|
applications such as ICU. XPLINK is enabled on a DLL-by-DLL basis, so
|
|
if you are considering using XPLINK in your application that uses ICU,
|
|
you should consider building the XPLINK-enabled version of ICU. You
|
|
need to set ICU's environment variable <code>OS390_XPLINK=1</code>
|
|
prior to invoking the make process to produce binaries that are enabled
|
|
for XPLINK.</p>
|
|
|
|
<p>Note: XPLINK, enabled for z/OS 1.2 and later, requires the PTF for
|
|
PQ69418 to build XPLINK-enabled binaries.</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>
|
|
<p>When you build ICU on a system such as z/OS 1.2, the binaries that
|
|
result can run on that level of the operating system and later, such as
|
|
z/OS 1.3 and z/OS 1.4. It's possible that you may have a z/OS 1.4
|
|
system and, for example, need to deliver binaries on z/OS 1.2 and
|
|
above. z/OS gives you this ability by targetting the complier and
|
|
linker to run at the older level, thereby producing the desired
|
|
binaries.</p>
|
|
|
|
<p>To set the compiler and LE environment to OS/390 2.10,
|
|
specify the following:</p>
|
|
<pre>
|
|
<samp>./runConfigureICU OS390V2R10</samp>
|
|
</pre>
|
|
|
|
<p>To set the compiler and LE environment to z/OS 1.2 specify the

following:</p>
|
|
<pre>
|

<samp>./runConfigureICU zOSV1R2</samp>
|
|
</pre>
|

</ul>
|

|
|
<h4>z/OS (Batch/PDS) support outside the UNIX system services
|
|
environment</h4>
|
|
|
|
<p>By default, ICU builds its libraries into the UNIX file system (HFS). In
|
|
addition, there is a z/OS specific environment variable (OS390BATCH) 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 non-UNIX support including
|
|
the batch environment. 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 data sets (the native file system). Turning on OS390BATCH does not
|
|
turn off the normal z/OS UNIX build. This means that the The z/OS UNIX
|
|
(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 UNIX
|
|
file system.</p>
|
|
|
|
<p>A data set is roughly equivalent to a UNIX or Windows file. For most
|
|
kinds of data sets the operating system maintains record boundaries. UNIX
|
|
and Windows files are byte streams. Two kinds of data sets are PDS and
|
|
PDSE. Each data set of these two types contains a directory. It is like a
|
|
UNIX directory. Each "file" is called a "member". Each member name is
|
|
limited to eight bytes, normally EBCDIC.</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 for the DLL file 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>(Only when OS390_STUBDATA=1)</i></samp>
|
|
</pre>
|
|
|
|
<p>You should point the LOADMOD environment variable at a partitioned data
|
|
set extended (PDSE) and point the LOADEXP environment variable at a
|
|
partitioned data set (PDS). The PDSE can be allocated with the following
|
|
attributes:</p>
|
|
<pre>

|
|
<p>ICU Reference Release 2.4 contains partial support for the iSeries

platform. After building ICU and running the tests, you may notice that
|

some of the formatting tests fail. The formating failures can be ignored
|

<h2><a name="HowToPackage" href="#HowToPackage">How To Package ICU</a></h2>
|
|
|
|
<p>There are many ways that a person can package ICU with their software
|
|
products. Usually only the libraries need to be considered for
|
|
packaging.</p>
|
|
|
|
<p>On Unix, you should have used "<tt>gmake install</tt>" to make it easier
|
|
to develop and package ICU. The bin, lib and include directories are needed
|
|
to develop applications that use ICU. These directories will be created
|
|
relative to the "<tt>--prefix=</tt><i>dir</i>" configure option (See <a
|
|
href="#HowToBuildUnix">above</a>). When ICU is built on Windows, a similar
|
|
directory structure is built.</p>
|
|
|
|
<p>When changes have been made to the standard ICU distribution, it is
|
|
recommended that at least one of the following guidelines be followed for
|
|
special packaging.</p>
|
|
|
|
<ol>
|
|
<li>Add a suffix name to the library names. This can be done with the
|
|
--with-library-suffix configure option.</li>
|
|
|
|
<li>The installation script should install the ICU libraries into the
|
|
application's directory.</li>
|
|
</ol>
|
|
|
|
<p>Following these guidelines prevents other applications that use a
|
|
standard ICU distribution from conflicting any libraries that you need. On
|
|
operating systems that do not have a standard C++ ABI (name mangling) for
|
|
compilers, it is recommended to do this special packaging anyway. More
|
|
details on customizing ICU are available in the <a href=
|
|
"http://oss.software.ibm.com/icu/userguide/">User's Guide</a>. The <a href=
|
|
"#SourceCode">ICU Source Code Organization</a> section of this readme.html
|
|
gives a more complete description of the libraries.</p>

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

<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. Here are some of the cases when the global
|
|
mutex is not initialized:</p>
|
|
|
|
<ul>
|
|
<li>Static ICU libraries are used.</li>
|
|
|
|
<li>ICU is used on Mac OS X</li>
|
|
|
|
<li>ICU is used on HP-UX and the program's main() function is not
|
|
declared in a C++ file.</li>
|
|
</ul>
|
|
|
|
<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.
|
|
If you do not have a multithreaded application, you do not need to worry
|
|
about the global mutex.</p>
|
|
|
|
<h3><a name="MakeICUSmaller" href="#MakeICUSmaller">How to Make ICU
|
|
Smaller</a></h3>
|
|
|
|
<p>For some environments, ICU "is too large". There are two ways to remove
|
|
parts and make it smaller: Remove some of its library code modules from the
|
|
build (reducing functionality), or remove some of its data (possibly
|
|
reducing only codepage/locale/etc. coverage without sacrificing overall
|
|
functionality). For details about reducing the data size see the <a href=
|
|
"http://oss.software.ibm.com/icu/userguide/">User Guide</a> "ICU Data"
|
|
chapter.</p>
|
|
|
|
<p>The header file <code>source/common/unicode/uconfig.h</code> contains
|
|
source-code-level "switches" corresponding to <code>#if</code> directives
|
|
in the ICU source code. Setting one of the <code>UCONFIG_NO_...</code>
|
|
switches to 1 (by setting <code>CFLAGS/CPPFLAGS</code> or adding a

<code>#define</code> at the beginning of <code>uconfig.h</code>) turns off
|
|
the code associated with one of the ICU service modules. Setting one of the
|
|
<code>UCONFIG_ONLY_...</code> switches to 1 turns off all modules that are
|
|
not essential for the functioning of the associated "only" service. For the
|
|
current set of available switches see <code>uconfig.h</code> itself.</p>
|
|
|
|
<p>When a source code module is turned off, then the data-building
|
|
makefiles should be modified to not generate the data files that are used
|
|
with that module. Some of the data-generating genxyz tools rely on the
|
|
module itself to build its data; they will generate dummy data files to
|
|
satisfy the dependencies of the unmodified makefiles (to make these
|
|
switches easily testable). Other data files for which the tools do not rely
|
|
on the related library modules (e.g., mapping tables [<code>.cnv</code>]
|
|
and transliterator files [<code>.res</code>, from
|
|
<code>source/data/translit/</code>]) continue to be built unless the data
|
|
makefiles are modified. For further details on data building see the <a

<h3><a name="#CharStrings" href="#CharStrings">char * strings in ICU</a></h3>
|
|
|
|
<p>The C/C++ languages do not provide a portable way to specify Unicode
|
|
code point or string literals other than with arrays of numeric constants.
|
|
For convenience, ICU4C tends to use char * strings in places where only
|
|
"invariant characters" are used — a portable subset of the 7-bit ASCII
|
|
repertoire — so that locale IDs, charset names, resource bundle item keys
|
|
and similar can be easily specified as string literals in the source code.
|
|
The same types of strings are also stored as "invariant character" char *
|
|
strings in the ICU data files.</p>
|
|
|
|
<p>ICU has hardcoded mapping tables in <code>source/common/putil.c</code>
|
|
to convert invariant characters to and from Unicode without using a full
|
|
ICU converter.
|
|
These tables must match the encoding of string literals in the ICU code
|
|
as well as in the ICU data files.</p>
|
|
|
|
<p><strong>Important: </strong>ICU assumes that at least the
|
|
invariant characters always have the same codes as is common on platforms
|
|
with the same charset family (ASCII vs. EBCDIC).
|
|
<em>ICU has not been tested on platforms where this is not the case.</em></p>
|
|
|
|
<p>Some usage of char * strings in ICU assumes the system charset
|
|
instead of invariant characters;
|
|
such strings are only handled with the default converter.
|
|
See the following section.
|
|
(The system charset is usually a superset of the invariant characters.)</p>
|
|
|
|
<p>The following are the ASCII and EBCDIC code values for all of the
|
|
invariant characters (see also unicode/utypes.h):</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="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 application 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>

<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="PlatformDependenciesNew" href=

|
"#PlatformDependenciesNew">Porting To A New Platform</a></h3>
|
|
|
|
<p>If you are using ICU's Makefiles to build ICU on a new platform, there
|
|
are a few places where you will need to add or modify some files. If you
|
|
need more help, you can always ask the icu4c-support mailing list. Once you
|
|
have finished porting ICU to a new platform, it is recommended that you
|
|
contribute your changes back to ICU via the icu4c-support mailing list.
|
|
This will make it easier for everyone to benefit from your work.</p>
|
|
|
|
<p>Try to follow the build steps from the <a href=
|
|
"#HowToBuildUnix">Unix</a> build instructions. If the configure script
|
|
fails, then you will need to modify some files. Here are the usual steps
|
|
for porting to a new platform:<br>
|
|
</p>
|
|
|
|
<ol>
|
|
<li>Create an mh file in icu/source/config/. You can use mh-linux or a
|
|
similar mh file as your base configuration.</li>
|
|
|
|
<li>Modify icu/source/aclocal.m4 to recognize your platform's mh
|
|
file.</li>
|
|
|
|
<li>Modify icu/source/configure.in to properly set your <b>platform</b> C
|
|
Macro define.</li>
|
|
|
|
<li>Run <a href="http://www.gnu.org/software/autoconf/">autoconf</a> in
|
|
icu/source/ without any options. The autoconf tool is standard on most
|
|
Linux systems.</li>
|
|
|
|
<li>If you have any optimization options that you want to normally use,
|
|
you can modify icu/source/runConfigureICU to specify those options for
|
|
your platform.</li>
|
|
|
|
<li>Build and test ICU on your platform. It is very important that you
|
|
run the tests. If you don't run the tests, there is no guarentee that you
|
|
have properly ported ICU.</li>
|

<h3><a name="PlatformDependenciesImpl" href=

"#PlatformDependenciesImpl">Platform Dependent Implementations</a></h3>
|
|
|
|
<p>The platform dependencies have been mostly isolated into the following

|
|
|
|
<li>int64_t and uint64_t. If the platform does not support 64 bit
|
|
values, the macro <tt>U_INT64_T_UNAVAILABLE</tt> must be defined. For
