<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 220 codepages</li>
|
|
|
|
<li>Locale data for more than 250 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 ICU4J 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="Download" href="#Download" id="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://www.icu-project.org/download/">http://www.icu-project.org/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. </li>
|
|
|
|
<li><strong>Subversion 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 Subversion repository to
|
|
ensure that you have the most recent version of all of the files. See our
|
|
<a href="http://www.icu-project.org/repository/">source
|
|
repository</a> for details.</li>

<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://www.icu-project.org/userguide/design.html">ICU Architectural
|
|
Design</a> section of the User's Guide 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>

changes are made to this directory.</p>
|
|
|
|
<p>If some of the following directories are missing, it's probably

<ul>
|
|
<li><b>in/</b> A directory that contains a pre-built data library for

|
ICU. A standard source code package will contain this file without

|
several of the following directories. This is to simplify the build

|
process for the majority of users and to reduce platform porting

issues.</li>

<li><b>locales/</b> These .txt files contain ICU language and
|
|
culture-specific localization data. Two special bundles are
|
|
<b>root</b>, which is the fallback data and parent of other bundles,
|
|
and <b>index</b>, which contains a list of installed bundles. The
|
|
makefile <b>resfiles.mk</b> contains the list of resource bundle
|
|
files.</li>
|
|
|
|
<li><b>mappings/</b> Here are the code page converter tables. These
|
|
.ucm files contain mappings to and from Unicode. These are compiled
|
|
into .cnv files. <b>convrtrs.txt</b> is the alias mapping table from
|
|
various converter name formats to ICU internal format and vice versa.
|
|
It produces cnvalias.icu. The makefiles <b>ucmfiles.mk,
|
|
ucmcore.mk,</b> and <b>ucmebcdic.mk</b> contain the list of
|
|
converters to be built.</li>
|

<li><b>translit/</b> This directory contains transliterator rules as
|
|
resource bundles, a makefile <b>trnsfiles.mk</b> containing the list

of installed system translitaration files, and as well the special
|
|
bundle <b>translit_index</b> which lists the system transliterator
|
|
aliases.</li>

<li><b>unidata/</b> This directory contains the Unicode data files.
|
|
Please see <a href=
|
|
"http://www.unicode.org/">http://www.unicode.org/</a> for more
|
|
information.</li>
|
|
|
|
<li><b>misc/</b> The misc directory contains other data files which
|
|
did not fit into the above categories. Currently it only contains
|
|
time zone information, and a name preperation file for <a href=
|
|
"http://www.ietf.org/rfc/rfc3490.txt">IDNA</a>.</li>

</ul>
|
|
|
|
<p>If you are creating a special ICU build, you can set the ICU_DATA
|
|
environment variable to the out/ or the out/build/ directories, but

this is generally discouraged because most people set it incorrectly.

<ul>
|
|
<li>Microsoft Windows 2000 or above</li>
|
|
|

|
|
|
|
<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.sln" workspace
|
|
file in Microsoft Visual Studio 2003. (This solution includes all the
|
|
International Components for Unicode libraries, necessary ICU building
|
|
tools, and the test suite projects). Please see the <a href=
|
|
"#HowToBuildWindowsCommandLine">command line note below</a> if you want to
|
|
build from the command line instead.</li>
|
|
|
|
<li>Set the active platform to "Win32" or "x64" (See <a href="#HowToBuildWindowsPlatform">Windows platform note</a> below)
|
|
and configuration to "Debug" or "Release" (See <a href="#HowToBuildWindowsConfig">Windows configuration note</a> below).</li>
|
|
|
|
<li>Choose the "Build" menu and select "Rebuild Solution". 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 startup
|
|
project to "intltest", and press Ctrl+F5 to run it. Make sure that it
|
|
passes without any errors.</li>
|
|
|
|
<li>Run the C test suite, "cintltst". To do this: set the active startup

|
project to "cintltst", and press Ctrl+F5 to run it. Make sure that it
|
|
passes without any errors.</li>
|
|
|
|
<li>Run the I/O test suite, "iotest". To do this: set the active startup
|
|
project to "iotest", and press Ctrl+F5 to run it. Make sure that it passes
|
|
without any errors.</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

|
application directory.</li>

|
|
|
|
<p>Building International Components for Unicode with this configuration
|
|
requires:</p>
|
|
|
|
<ul>
|
|
<li>Microsoft 2000 or above</li>
|
|
|
|
<li>Microsoft Visual C++ 2003 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 command prompt. The Microsoft
|
|
Visual C++ compiler will not work with a bash command prompt.</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 8\VC\bin\vcvars32.bat</tt>" can be used for 32-bit builds
|
|
<strong>or</strong> "<tt>C:\Program Files (x86)\Microsoft Visual Studio
|
|
8\VC\bin\amd64\vcvarsamd64.bat</tt>" can be used for 64-bit builds on
|
|
Windows x64.</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="#HowToWindowsConfigureICU">Windows
|
|
configuration note</a> and non-functional configure options 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=

<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. 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>The makedep and GNU make tools are required for building ICU. If it
|
|
is not already installed on your system, it is available at the <a href=
|
|
"http://www.ibm.com/servers/eserver/zseries/zos/unix/redbook/">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. Failure to add these
|
|
tools to your PATH will cause ICU build failures or cause pkgdata to fail
|
|
to run.</li>
|
|
|
|
<li>Since USS does not support using the mmap() function over NFS, it is
|
|
recommended that you build ICU on a local filesystem. Once ICU has been
|
|
built, you should not have this problem while using ICU when the data
|
|
library has been built as a shared library, which is this is the default
|
|
setting.</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>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. Native floating point support is sufficient
|
|
for codepage conversion, resource bundle and UnicodeString operations, but
|
|
the Format APIs require IEEE binary floating point.</li>
|
|
|
|
<li>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. The XPLINK option, which is available for z/OS 1.2 and later,
|
|
requires the PTF PQ69418 to build XPLINK enabled binaries.</li>
|
|
|
|
<li>Currently in ICU 3.0, there is an issue with building on z/OS without
|
|
XPLINK and with the C++ iostream. By default, the iostream library on z/OS
|
|
is XPLINK enabled. If you are not building an XPLINK enabled version of
|
|
ICU, you should use the <code>--with-iostream=old</code> configure option
|
|
when using runConfigureICU. This will prevent applications that use the
|
|
icuio library from crashing.</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 libicui18n<i>XX</i>.dll,
|
|
libicuuc<i>XX</i>.dll, and libicudt<i>XX</i>e.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</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" id="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 use "<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 with 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://www.icu-project.org/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>

|
|
|
|
<h3><a name="ImportantNotesMultithreaded" href="#ImportantNotesMultithreaded"
|
|
id="ImportantNotesMultithreaded">Using ICU in a Multithreaded
|
|
Environment</a></h3>
|
|
|
|
<p>Some versions of ICU require calling the <code>u_init()</code> function
|
|
from <code>uclean.h</code> to ensure that ICU is initialized properly. In
|
|
those ICU versions, <code>u_init()</code> must be called before ICU is used
|
|
from multiple threads. There is no harm in calling <code>u_init()</code> in a
|
|
single-threaded application, on a single-CPU machine, or in other cases where
|
|
<code>u_init()</code> is not required.</p>
|
|
|
|
<p>In addition to ensuring thread safety, <code>u_init()</code> also attempts
|
|
to load at least one ICU data file. Assuming that all data files are packaged
|
|
together (or are in the same folder in files mode), a failure code from
|
|
<code>u_init()</code> usually means that the data cannot be found. In this
|
|
case, the data may not be installed properly, or the application may have
|
|
failed to call <code>udata_setCommonData()</code> or
|
|
<code>u_setDataDirectory()</code> which specify to ICU where it can find its
|
|
data.</p>
|
|
|
|
<p>Since <code>u_init()</code> will load only one or two data files, it
|
|
cannot guarantee that all of the data that an application needs is available.
|
|
It cannot check for all data files because the set of files is customizable,
|
|
and some ICU services work without loading any data at all. An application
|
|
should always check for error codes when opening ICU service objects (using
|
|
<code>ucnv_open()</code>, <code>ucol_open()</code>, C++ constructors,
|
|
etc.).</p>
|
|
|
|
<h4>ICU 3.4 and later</h4>
|
|
|
|
<p>ICU 3.4 self-initializes properly for multi-threaded use. It achieves this
|
|
without performance penalty by hardcoding the core Unicode properties data,
|
|
at the cost of some flexibility. (For details see Jitterbug 4497.)</p>
|
|
|
|
<p><code>u_init()</code> can be used to check for data loading. It tries to
|
|
load the converter alias table (<code>cnvalias.icu</code>).</p>
|
|
|
|
<h4>ICU 2.6..3.2</h4>
|
|
|
|
<p>These ICU versions require a call to <code>u_init()</code> before
|
|
multi-threaded use. The services that are directly affected are those that
|
|
don't have a service object and need to be fast: normalization and character
|
|
properties.</p>
|
|
|
|
<p><code>u_init()</code> loads and initializes the data files for
|
|
normalization and character properties (<code>unorm.icu</code> and
|
|
<code>uprops.icu</code>) and can therefore also be used to check for data
|
|
loading.</p>
|
|
|
|
<h4>ICU 2.4 and earlier</h4>
|
|
|
|
<p>ICU 2.4 and earlier versions were not prepared for multithreaded use on
|
|
multi-CPU platforms where the CPUs implement weak memory coherency. These
|
|
CPUs include: Power4, Power5, Alpha, Itanium. <code>u_init()</code> was not
|
|
defined yet.</p>

|
<h4><a name="ImportantNotesHPUX" href="#ImportantNotesHPUX" id=
|
|
"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/en/1405/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/en/1405/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>

<h5>Linking on Solaris</h5>

|
<p>In order to avoid synchronization and threading issues, developers are
|
|
<strong>suggested</strong> to strictly follow the compiling and linking
|
|
guidelines for multithreaded applications, specified in the following
|
|
document from Sun Microsystems. Most notably, pay strict attention to the
|
|
following statements from Sun:</p>
|
|
|
|
<blockquote>
|
|
<p>To use libthread, specify -lthread before -lc on the ld command line, or
|
|
last on the cc command line.</p>
|
|
|
|
<p>To use libpthread, specify -lpthread before -lc on the ld command line,
|
|
or last on the cc command line.</p>
|
|
</blockquote>
|
|
|
|
<p>Failure to do this may cause spurious lock conflicts, recursive mutex
|
|
failure, and deadlock.</p>

|
<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>
|

|
<p><strong>Windows 2000/XP</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.</p>
|
|
|
|
<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=
|

<h3><a name="ImportantNotesUNIX" href="#ImportantNotesUNIX" id=
|
|
"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>

|

|
|
<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://www.icu-project.org/contacts.html">icu-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 icu-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://www.icu-project.org/userguide/icudata.html">ICU
|
|
Data</a> chapter.</p>
|
|
|
|
<p>ICU 3.6 removes the requirement that ICU be completely built in the native
|
|
operating environment. It adds the icupkg 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>

|
|
|
|
<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, ppalmos.h,
|
|
..): Platform-dependent typedefs and defines:<br />
|
|
<br />
|
|
|
|
|
|
<ul>
|
|
<li>Generic types like UBool, int8_t, int16_t, int32_t, int64_t,
|
|
uint64_t etc.</li>
|
|
|
|
<li>U_EXPORT and U_IMPORT for specifying dynamic library import and
|
|
export</li>
|
|
|
|
<li><iostream> usability</li>
|
|
|
|
<li>Thread safety usability</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. We already supply working
|
|
implementations for many platforms that ICU builds on.<br />
|
|
<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>
