|
|
|
<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/index.html">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/2.8/index.html">ICU 2.8 download
|
|
page</a>.</p>
|
|
|
|
<h3><a name="News_Locale">Locale Identifier Changes</a></h3>
|
|
|
|
<p>The ICU locale identifier format has recently changed. In order to
|
|
improve support for RFC 3066 identifiers and to support keyword
|
|
identifiers, some minor breaking changes have been introduced. When your
|
|
application is working with POSIX locale identifiers or .NET locale
|
|
identifiers, you should use <code><a href=
|
|
"http://oss.software.ibm.com/icu/apiref/uloc_8h.html">uloc_canonicalize</a>()</code>
|
|
to convert it to an ICU locale identifier. It was an undocumented feature
|
|
that you could pass a POSIX locale to ICU, and ICU would convert it for you
|
|
automatically. For example, if you used @EURO or @PREEURO to identify
|
|
certain currencies, you should now be using the "@currency=" keyword for
|
|
the locale identifiers. If you use the <code>uloc_canonicalize()</code>
|
|
function, it will convert the @PREEURO variants to the proper ICU locale
|
|
identifier. For example, it will convert "fr-fr@PREEURO" to
|
|
"fr_FR@currency=FRF". More information about keywords can be found in the
|
|
<a href="http://oss.software.ibm.com/icu/userguide/locale.html">Locale
|
|
Section</a> of the User's Guide and <a href=
|
|
"http://www.openi18n.org/specs/ldml/1.0/ldml-spec.htm">on the OpenI18N
|
|
site</a>.</p>
|
|
|
|
<p>Some ISO 15924 script codes are used in some RFC 3066 language tags.
|
|
This is especially helpful when you need to differentiate cases where a
|
|
language can be written with more than one script. Since ICU now supports
|
|
ISO 15924 script codes in the locale identifier, you can now specify
|
|
locales like "zh_Hant" to specify Traditional Chinese. Previously, people
|
|
had to use "zh_TW" to specify Traditional Chinese, which isn't quite
|
|
correct because the locale identifier is specifying the language of a
|
|
region and not the type of language. The current locale identifiers, like
|
|
en_US, still work, and do not require any changes in your code. Future
|
|
versions of ICU will move the data into the proper locale resources, and
|
|
the locale infrastructure will be improved.</p>
|
|
|
|
<h3><a name="News_Library_Names">Static Library Names and AIX
|
|
linking</a></h3>
|
|
|
|
<p>Previously static and shared library names had the same naming scheme,
|
|
except the file extension was different between the filenames. For example,
|
|
the shared common library was called libicuuc.so, and the static common
|
|
library was called libicuuc.a on many Unix type machines. It has come to
|
|
our attention, that Windows import library names and static library names
|
|
can have the same name, and when the -brtl linker option is removed the
|
|
static and shared libraries have the same filename extension, which is
|
|
".a". The -brtl linker option on AIX has been removed at several people's
|
|
request.</p>
|
|
|
|
<p>In order to differentiate between the two library names on all
|
|
platforms, static libraries now use an "s" as a prefix to differentiate
|
|
between the shared and static libraries. For example, "libicuuc.a" is now
|
|
"lib<strong>s</strong>icuuc.a". This means that if you used "-licuuc" to
|
|
link the common library into your application, you now need to use
|
|
"-lsicuuc".</p>
|
|
|
|
<h3><a name="News_ICUIO">ICUIO Library Changes</a></h3>
|
|
|
|
<p>The ICUIO library is still unsupported (this was previously called the
|
|
ustdio library), and some breaking fixes have been made to the library. %S
|
|
should be used for UTF-16 strings, and %C should be used for UChar for the
|
|
format strings. The %K and %U format specifiers are deprecated and will be
|
|
removed in a future version of ICU. Also u_fgets now uses the same argument
|
|
ordering as stdio fgets, which will make it easier for people to migrate
|
|
their existing stdio implementations to use ICUIO. Fortunately, u_fgets now
|
|
follows the Unicode algorithm for detecting hard line breaks, and some
|
|
performance enhancements to this library have been implemented so that most
|
|
of the formatting and parsing functions will run faster.</p>
|
|
|
|
<h3><a name="News_Library_Init">Library Initialization</a></h3>
|
|
|
|
<p>ICU4C 2.6 introduces a library initialization function. It is required
|
|
to call it before using any ICU services in a multi-threaded environment.
|
|
For details please see the <a href=
|
|
"http://oss.software.ibm.com/icu/apiref/index.html">documentation</a> of
|
|
<code>u_init()</code> in the <code>unicode/uclean.h</code> header file.</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/index.html">http://oss.software.ibm.com/icu/download/index.html</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>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">Windows configuration 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">batch configuration 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>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 2002.
|
|
It is recommended that you use the
|
|
"<i><ICU></i>\source\allinone\allinone.sln" solution workspace to
|
|
build ICU. The instructions for building with Visual Studio .NET are
|
|
similar to the instructions for Visual Studio .NET. If you have Microsoft
|
|
Visual Studio .NET 2003 the Visual Studio .NET 2002 project files will
|
|
automatically be converted to 2003 project files when you open the solution
|
|
workspace for the first time.</p>

<h3><a name="HowToBuildCygwin" href="#HowToBuildCygwin">How To Build And
|
|
Install On Windows with Cygwin</a></h3>
|
|
|
|
<p>Building International Components for Unicode with this configuration
|
|
requires:</p>
|
|
|
|
<ul>
|
|
<li>Microsoft NT 4.0 or above, or Windows 98 or above</li>
|
|
|
|
<li>Microsoft Visual C++ 6.0 or above (when gcc isn't used).</li>
|
|
|
|
<li>
|
|
Cygwin with the following installed:
|
|
|
|
<ul>
|
|
<li>bash</li>
|
|
|
|
<li>GNU make</li>
|
|
|
|
<li>man (if you plan to look at the man pages)</li>
|
|
</ul>
|
|
</li>
|
|
</ul>
|
|
|
|
<p>There are two ways you can build ICU with Cygwin. You can build with gcc
|
|
or Microsoft Visual C++. If you use gcc, the resulting libraries and tools
|
|
will depend on the Cygwin environment. If you use Microsoft Visual C++, the
|
|
resulting libraries and tools do not depend on Cygwin and can be more
|
|
easily distributed to other Windows computers (the generated man pages and
|
|
shell scripts still need Cygwin). To build with gcc, please follow the "<a
|
|
href="#HowToBuildUNIX">How To Build And Install On UNIX</a>" instructions,
|
|
while you are inside a Cygwin bash shell. To build with Microsoft Visual
|
|
C++, please use the following instructions:</p>
|
|
|
|
<ol>
|
|
<li>Start the Windows "Command Prompt" window (this is different from the
|
|
gcc build, which requires the Cygwin Bash Shell).</li>
|
|
|
|
<li>If the computer isn't set up to use Visual C++ from the command line,
|
|
you need to run VCVARS32.BAT (for example: "<tt>C:\Program
|
|
Files\Microsoft Visual Studio\VC98\Bin\VCVARS32.BAT</tt>").</li>
|
|
|
|
<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>Change directory to "icu/source", which is where you unzipped
|
|
ICU.</li>
|
|
|
|
<li>Run "<tt>bash <a href="source/runConfigureICU">./runConfigureICU</a>
|
|
Cygwin/MSVC</tt>" (See <a href="#HowToConfigureICU">configuration
|
|
note</a> below).</li>
|
|
|
|
<li>Type <tt>"make"</tt> to compile the libraries and all the data files.
|
|
This make command should be GNU make.</li>
|
|
|
|
<li>Optionally, type <tt>"make check"</tt> to run the test suite, which
|
|
checks for ICU's functionality integrity (See <a href=
|
|
"#HowToTestWithoutGmake">testing note</a> below).</li>
|
|
|
|
<li>Type <tt>"make install"</tt> to install ICU. If you used the
|
|
--prefix= option on configure or runConfigureICU, ICU will be installed
|
|
to the directory you specified. (See <a href=
|
|
"#HowToInstallICU">installation note</a> below).</li>

<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.
|
|
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
|
|
OS/390 2.6 and later) IEEE 754 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=0
|
|
will cause the z/OS version of ICU to be built without IEEE floating
|
|
point support and use the native hexadecimal floating point. By default
|
|
ICU is built with IEEE 754 support.</p>
|
|
|
|
<p><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 require IEEE binary
|
|
floating point.</p>
|
|
|
|
<p>Examples for configuring ICU:<br>
|
|
Debug build: <code>./runConfigureICU --enable-debug zOS</code><br>
|
|
Release build: <code>./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, which is enabled for z/OS 1.2 and later, requires the
|
|
PTF 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, but you may need to deliver binaries on z/OS 1.2 and above.
|
|
z/OS gives you this ability by targeting 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, "<code>./runConfigureICU OS390V2R10</code>"</p>
|
|
|
|
<p>To set the compiler and LE environment to z/OS 1.2 specify the
|
|
following, "<code>./runConfigureICU zOSV1R2</code>"</p>
|
|
</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 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 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>IN --> libicui18n<i>XX</i>.dll
|
|
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>
|

<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 the <a
|
|
href="#HowToBuildUNIX">UNIX build instructions</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/index.html">User's Guide</a>.
|

Using ICU</a></h2>

|
|
<h3><a name="ImportantNotesCPlusPlus" href="#ImportantNotesCPlusPlus">Using
|
|
ICU in a Multithreaded Environment</a></h3>
|
|
|
|
<p>Upon the first usage of most ICU APIs, the global mutex will get
|
|
initialized properly, but you can use the <code>u_init()</code> function
|
|
from uclean.h to ensure that it is initialized properly. Without calling
|
|
this function from a single thread, the data caches inside ICU may get
|
|
initialized more than once from multiple threads, which may cause memory
|
|
leaks and other problems. There is no harm in calling <code>u_init()</code>
|
|
in a single threaded application.</p>

|
|
|
<h4><a name="ImportantNotesHPUX" href="#ImportantNotesHPUX">Using ICU in a
|
|
Multithreaded Environment on HP-UX</a></h4>
|
|
|
|
<p>If you are building ICU with a newer aCC compiler and you are planning
|
|
on using the older <iostream.h> instead of the newer
|
|
<iostream>, you will need to use a special configure flag before
|
|
building ICU. By default, the aCC <a href=
|
|
"http://docs.hp.com/hpux/onlinedocs/dev/aCC/a_03_30/options.htm#optioncap-AA">
|
|
-AA</a> flag is used on HP-UX when the compiler supports that option in
|
|
order to make ICU thread safe with RogueWave and other libraries using the
|
|
2.0 Standard C++ library. Your applications that use ICU will also need to
|
|
use the <a href=
|
|
"http://docs.hp.com/hpux/onlinedocs/dev/aCC/a_03_30/options.htm#optioncap-AA">
|
|
-AA</a> compiler flag. To turn off this behavior in ICU, you will need to
|
|
use the --with-iostream= old configure option when you first use
|
|
runConfigureICU.</p>
|
|
|
|
<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" (a portable subset of the 7-bit ASCII repertoire)
|
|
are used. This allows locale IDs, charset names, resource bundle item keys
|
|
and similar items to 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 hard coded 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 byte 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 over
|
|
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 <a href=

|
"http://oss.software.ibm.com/icu/archives/">icu4c-support mailing list</a>.
|
|
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>
|
|
|
|
<h4>Data For a New Platform</h4>
|
|
|
|
<p>For some people, it may not be necessary for completely build ICU. Most
|
|
of the makefiles and build targets are for tools that are used for building
|
|
ICU's data, and an application's data (when an application uses ICU
|
|
resource bundles for its data).</p>
|
|
|
|
<p>Data files can be built on a different platform when both platforms
|
|
share the same endianness and the same charset family. This assertion does
|
|
not include platform dependent DLLs/shared/static libraries. For details
|
|
see the User Guide <a href=
|
|
"http://oss.software.ibm.com/icu/userguide/icudata.html">ICU Data</a>
|
|
chapter.</p>
|
|
|
|
<p>ICU 2.8 removes the requirement that ICU be completely built in the
|
|
native operating environment. It adds the icuswap tool which can be run on
|
|
any platform to turn binary ICU data files from any one of the three
|
|
formats into any one of the other data formats. This allows a application
|
|
to use ICU data built anywhere to be used for any other target
|
|
platform.</p>
|
|
|
|
<p><strong>WARNING!</strong> Building ICU without running the tests is not
|
|
recommended. The tests verify that ICU is safe to use. It is recommended
|
|
that you try to completely port and test ICU before using the libraries for
|
|
your own application.</p>
|
|
|
|
<h4>Adapting Makefiles For a New Platform</h4>
|
|
|
|
<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>
|
|
</ol>

<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>

|
|
<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>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>
