<h2><a name="Introduction">Introduction</a></h2>
|
|
|
|
<p>Today's software market is a global one in which it is desirable to
|
|
develop and maintain one application that supports a wide variety of
|
|
national languages. International Components for Unicode provides the
|
|
following tools to help you write language independent applications:</p>
|
|
|
|
<ul type="disc">
|
|
<li>Support for the latest Unicode standard</li>
|
|
|
|
<li>Resource bundles for storing and accessing localized
|
|
information</li>
|
|
|
|
<li>Number formatters for converting binary numbers into text strings
|
|
for meaningful display</li>
|
|
|
|
<li>Date and time formatters for converting internal time data into
|
|
text strings for meaningful display</li>
|
|
|
|
<li>Message formatters for putting together sequences of strings,
|
|
numbers dates and other format to create messages</li>
|
|
|
|
<li>Text collation supporting language sensitive comparison of
|
|
strings</li>
|
|
|
|
<li>Text boundary analysis for finding characters, word and sentence
|
|
boundaries</li>
|
|
|
|
<li>Changing simple data files rather than modifying program code
|
|
easily localizes applications written using these tools</li>
|
|
|
|
<li>Over 160 locales supported. Visit the <a href=
|
|
"http://oss.software.ibm.com/developerworks/opensource/icu/localeexplorer">
|
|
LocaleExplorer</a> on the ICU website for a demonstration and a full
|
|
list of supported locales or see the <a href=
|
|
"http://oss.software.ibm.com/cvs/icu/~checkout~/icu/data/index.txt">index
|
|
file</a> with the supported locales.</li>
|
|
</ul>
|
|
|
|
<p>It is possible to support additional locales by adding more locale
|
|
data files, with no code changes. Please refer to POSIX programmer's
|
|
Guide for details on what the ISO locale ID means.</p>
|
|
|
|
<p>This document will go into more detail on how to build and install ICU
|
|
on your machine. Once you start using ICU, the <a href=
|
|
"#UsageInformation">Where To Find More Information</a> section of this
|
|
document will be very helpful resource.</p>
|
|
|
|
<p>Your comments are important to making this release successful. We are
|
|
committed to fixing any bugs, and will also use your feedback to help
|
|
plan future releases.</p>

<h3><a name="NewsUnicodeVer">Support for Unicode 3.1</a></h3>
|
|
|
|
<p>The ICU data has been upgraded to support Unicode 3.1. This means that
|
|
the character property data and normalization has changed. Recent
|
|
versions of ICU already supported Unicode 3.0 data with UTF-16 surrogate
|
|
pairs.</p>
|
|
|
|
<h3><a name="NewsLicense">License Change</a></h3>
|
|
|
|
<p>The ICU projects (ICU4C and ICU4J) have changed their licenses from
|
|
the IPL (IBM Public License) to the X license. The X license is a
|
|
non-viral and recommended free software license that is compatible with
|
|
the GNU GPL license. This is effective starting with release 1.8.1 of
|
|
ICU4C and release 1.3.1 of ICU4J. All previous ICU releases will continue
|
|
to utilize the IPL. New ICU releases will adopt the X license. The users
|
|
of previous releases of ICU will need to accept the terms and conditions
|
|
of the X license in order to adopt the new ICU releases.</p>
|
|
|
|
<p>The main effect of the change is to provide GPL compatibility. The X
|
|
license is listed as GPL compatible, see the gnu page at <a href=
|
|
"http://www.gnu.org/philosophy/license-list.html#GPLCompatibleLicenses">http://www.gnu.org/philosophy/license-list.html#GPLCompatibleLicenses</a>.</p>
|
|
|
|
<p>The text of the X license is available at <a href=
|
|
"http://www.x.org/terms.htm">http://www.x.org/terms.htm</a>. The IBM
|
|
version contains the essential text of the license, omitting the
|
|
X-specific trademarks and copyright notices.</p>
|
|
|
|

|
|
"http://oss.software.ibm.com/icu/press.html">press announcement</a> and

FAQ</a>.</p>
|
|
|
|
<h3><a name="NewsCollation">Collation Improvements</a></h3>
|
|
|
|
<p>The collation framework has been reimplemented to make it faster,
|
|
Unicode Collation Algorithm compliant, and to make the locale-specific
|
|
collation data smaller (by separating it from the shared UCA data).<br>
|
|
<em>Sort keys and even some collation results have changed from ICU 1.6
|
|
and ICU 1.7.</em><br>
|
|
For details, see our <a href=
|
|
"http://oss.software.ibm.com/icu/develop/collation/">collation design
|

<h2><a name="WhatContain">What the International Components for Unicode
|
|
Contain</a></h2>
|
|
|
|
<p>There are two ways to download the ICU releases,</p>
|
|
|
|
<ul type="disc">
|
|
<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>
|
|
|
|
If packaged snapshot is named <strong>ICUXXXXXX.zip</strong> or
|
|
<strong>ICUXXXXXX.tgz</strong>, XXXXXX is the release version
|
|
number.<br>
|
|
Please unzip this file. It will reconstruct the source directory,
|
|
including 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. There are several ways to do this:
|
|
|
|
<ul type="circle">
|
|
<li>WebCVS:<br>
|
|
If you want to browse the code and only make occasional downloads,
|
|
you may want to use WebCVS. It provides a convenient, web-based
|
|
interface for browsing and downloading the latest version of the
|
|
ICU source code and documentation. You can also view each file's
|
|
revision history, display the differences between individual
|
|
revisions, determine which revisions were part of which official
|
|
release, and so on.</li>
|
|
|
|
<li>
|
|
WinCVS:<br>
|
|
If you will be doing serious work on ICU, you should probably
|
|
install a CVS client on your own machine so that you can do batch
|
|
operations without going through the WebCVS interface. On
|
|
Windows, we suggest the WinCVS client. The following is the
|
|
example instruction on how to download ICU via WinCVS:
|
|
|
|
<ol>
|
|
<li>Install the WinCVS client, which you can download from the
|
|
WinCVS home page.</li>
|
|
|
|
<li>In the WinCVS preferences, specify your CVSRoot to be
|
|
":pserver:anoncvs@oss.software.ibm.com:/usr/cvs/icu"<br>
|
|
with the password "anoncvs". To enter the CVSRoot value,
|
|
select "Preferences" from the "Cvs Admin" pull-down menu.
|
|
Authentication should be set to "'passwd' file on the cvs
|
|
server".</li>
|
|
|
|
<li>To "extract" the most recent version of ICU, select
|
|
"Checkout module" from the "Cvs Admin" menu. Specify "icu" for
|
|
the module name.</li>
|
|
</ol>
|
|
</li>
|
|
|
|
<li>CVS command line:<br>
|
|
You can also check out the repository anonymously on UNIX using
|
|
the following commands, after first setting your CVSROOT to point
|
|
to the ICU repository:<br>
|
|
<br>
|
|
<i>export
|
|
CVSROOT=:pserver:anoncvs@oss.software.ibm.com:/usr/cvs/icu<br>
|
|
cvs login CVS password: anoncvs<br>
|
|
cvs checkout icu<br>
|
|
cvs logout</i></li>
|
|
</ul>
|
|
</li>
|
|
</ul>
|
|
|
|
<p>For more details on how to download ICU directly from the web site,
|
|
please also see <a href=
|
|
"http://oss.software.ibm.com/icu/download/">http:/oss.software.ibm.com/icu/download/</a></p>
|
|
|
|
<p>Below, <strong>$Root</strong> is the placement of the icu directory in
|
|
your file system, like "drive:\...\icu" in your environment. "drive:\..."
|
|
stands for any drive and any directory on that drive that you chose to
|
|
install icu into.</p>

<u>udata.h</u> and <u>udata.c</u>: The data-accessing interface in
|
|
ICU is implemented such that there is a lot of flexibility for
|
|
reading a data file. Each platform can tune the performance of file
|
|
accessing for its environment by choosing to implement one of the
|
|
following options:<br>
|
|
<br>
|
|
|
|
|
|
<ul type="circle">
|
|
<li>DLL</li>
|
|
|
|
<li>Memory map</li>
|
|
|
|
<li>Plain text</li>
|
|
</ul>
|
|
<br>
|
|
</li>
|
|
|
|
<li>If you are changing the platform-dependent files, utypes.h and
|
|
putil.h may also be interesting, but they shouldn't have to be changed.
|
|
If you think any other files than the ones mentioned above have
|
|
platform dependencies, please contact us.</li>
|
|
|
|
<li>For the Intltest test suite, intltest.cpp in
|
|
"icu/source/test/intltest/" contains the method pathnameInContext,
|
|
which must also be adapted to any new platform.</li>

<h3><a name="HowToBuildWindows">How To Build And Install On
|
|
Windows</a></h3>
|
|
|
|
<p>Building International Components for Unicode requires:</p>
|
|
|
|
<ul type="disc">
|
|
<li>Microsoft NT 3.51 and above, or Windows 95 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>The steps are:</p>
|
|
|
|
<ol start="1" type="1">
|
|
<li>Unzip the icu-XXXX.zip file, type "unzip -a icu-XXXX.zip -d
|
|
drive:\directory" under command prompt or use WinZip.
|
|
drive:\directory\icu is the root ($Root) directory (you may but don't
|
|
need to place "icu" into another directory). If you change the root,
|
|
you will change the project settings accordingly in EACH makefile in
|
|
the project, updating the "include" and "library" paths.</li>
|
|
|
|
<li>Set the environment variable <strong>ICU_DATA</strong> to the full
|
|
pathname of the data directory. The trailing "\" is required after the
|
|
directory name (e.g. "$Root\source\data\" will work, but the value
|
|
"$Root\source\data" is not acceptable). This environment variable
|
|
indicates where the locale data files and conversion mapping tables are
|
|
located.</li>
|
|
|
|
<li>Be sure that the ICU binary directory, $Root\bin\, is included in
|
|
the <strong>PATH</strong> environment variable. The tests may not work
|
|
without the DLL files in the path.</li>
|
|
|
|
<li>Set the <strong>TZ</strong> environment variable to
|
|
<strong>PST8PDT</strong>. The tests will not work in any other
|
|
timezone.</li>
|
|
|
|
<li>Use Microsoft Visual C++ 6.0 to open the
|
|
"$Root\source\allinone\allinone.dsw" workspace (This workspace includes
|
|
all the International Components for Unicode libraries, necessary ICU
|
|
building tools, and the intltest and cintltest test suite
|
|
projects).</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.</li>
|
|
</ol>
|
|
|
|
<p><a name="HowToBuildWindowsConfig"><strong>Setting Active Configuration
|
|
Note:</strong></a> To set the active configuration, two different
|
|
possibilities are:</p>
|
|
|
|
<ul type="disc">
|
|
<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
|
|
test programs as well as the tools for generating binary locale data
|
|
files. The "makedata" project will be run automatically to convert the
|
|
locale data files from text format into icudata.dll.</p>

|
<h3><a name="HowToBuildUnix">How To Build And Install On Unix</a></h3>
|
|
|
|
<p>Building International Components for Unicode on Unix requires:</p>
|
|
|
|
<p>A UNIX C++ compiler, (gcc, cc, xlc_r, etc...) installed on the target
|
|
machine. A recent version of GNU make (3.7+). For a list of OS/390 tools
|
|
please view the <a href="#HowToBuildOS390">OS/390 build section</a> of
|
|
this document for further details.</p>
|
|
|
|
<p>The steps are:</p>
|
|
|
|
<ol start="1" type="1">
|
|
<li>Decompress the icuXXXX.tar (or icuXXXX.tgz) file and use pax.</li>
|
|
|
|
<li>Before running the test programs or samples, please set the
|
|
environment variable <strong>ICU_DATA</strong>, the full pathname of
|
|
the data directory, to indicate where the locale data files and
|
|
conversion mapping tables are. If this variable is not set, the default
|
|
user data directory will be used. The trailing "/" is required after
|
|
the directory name (e.g. "$Root/source/data/" will work, but the value
|
|
"$Root/source/data" is not acceptable). When you are running individual
|
|
tests, the <strong>TZ</strong> environment variable needs to be set to
|
|
<strong>PST8PDT</strong>. Normally "make check" does this for you
|
|
automatically.</li>
|
|
|
|
<li>Change directory to the "icu/source".</li>
|
|
|
|
<li>If it is not already set, please set the executable flag for the
|
|
following files (by executing 'chmod +x' command): runConfigureICU,
|
|
configure, install-sh and config.*,</li>
|
|
|
|
<li>Run the <a href="source/runConfigureICU">runConfigureICU</a> script
|
|
for your platform. If you are not using the runConfigureICU script or
|
|
your platform is not supported by the script, you need to set your CC,
|
|
CXX, CFLAGS and CXXFLAGS environment variables, and type "./configure".
|
|
You can type "./configure --help" to print the available options.</li>
|
|
|
|
<li>
|
|
Type "gmake" to compile the libraries and all the data files.
|
|
|
|
<div class="indent">
|
|
<strong>Note:</strong> On OS/390, both IEEE binary floating point
|
|
and native S/390 hexadecimal floating point calculations are
|
|
supported. The default is to build with native floating-point
|
|
support. Please set the environment variable IEEE390=1 if you would
|
|
like to make the ICU DLLs with IEEE floating point support.
|
|
</div>
|
|
</li>
|
|
|
|
<li>Optionally, type "gmake check" to verify the test suite.</li>
|
|
|
|
<li>Type "gmake install" to install.</li>
|
|
</ol>
|
|
|
|
<p>Some platforms use package management tools to control the
|
|
installation and uninstallation of files on the system, as well as the
|
|
integrity of the system configuration. You may want to check if ICU can
|
|
be packaged for your package management tools by looking into the
|
|
"packaging" directory. (Please note that if you are using a snapshot of
|
|
ICU from CVS, it is probable that the packaging scripts or related files
|
|
are not up to date with the contents of ICU at this time, so use them
|
|
with caution.)</p>
|
|
|
|
<h3><a name="HowToBuildOS390">OS/390 (zSeries) Platform</a></h3>
|
|
|
|
<p>If you are building on the OS/390 UNIX System Services platform, it is
|
|
important that you understand a few details:</p>
|
|
|
|
<ul>
|
|
<li>The gnu utilities gmake and gzip/gunzip are needed and can be
|
|
obtained for OS/390 from <a href=
|
|
"http://www.ibm.com/servers/eserver/zseries/zos/unix/bpxa1ty1.html#opensrc">
|
|
z/OS Unix - Tools and Toys</a>. Documentation on these tools can be
|
|
found at the <a href=
|
|
"http://publib-b.boulder.ibm.com/Redbooks.nsf/RedbookAbstracts/sg245944.html">
|
|
Open Source Software for OS/390 UNIX</a> Red Book.</li>
|
|
|
|
<li>
|
|
Encoding considerations: The source code assumes that it is compiled
|
|
with codepage ibm-1047 (to be exact, the UNIX System Services variant
|
|
of it). The pax command converts all of the source code files from
|
|
ASCII to codepage ibm-1047 (USS) EBCDIC. However, some files are
|
|
binary files and must not be converted, or must be converted back to
|
|
their original state. You can use the <a href=
|
|
"as_is\os390\unpax-icu.sh">unpax-icu.sh</a> script to do this for you
|
|
automatically. It will unpackage the tar file and convert all the
|
|
necessary files for you automatically. The files that must not be
|
|
converted to ibm-1047 are the following:
|
|
|
|
<ul>
|
|
<li>All UTF-8 files</li>
|
|
|
|
<li>icu/data/*.brk</li>
|
|
|
|
<li>icu/source/test/testdata/uni-text.bin</li>
|
|
|
|
<li>icu/source/test/testdata/th18057.txt</li>
|
|
</ul>
|
|
Such a conversion can be done using iconv:<br>
|
|
<code>iconv -f IBM-1047 -t ISO8859-1 uni-text.bin >
|
|
uni-text.bin</code>
|
|
</li>
|
|
|
|
<li>
|
|
DLL directories and the LIBPATH setting: Building and testing ICU
|
|
needs the ICU libraries on the LIBPATH. In other words, the LIBPATH
|
|
should contain (each path prepended with the root directory that
|
|
contains the icu directory):
|
|
|
|
<ul>
|
|
<li>icu/source/common</li>
|
|
|
|
<li>icu/source/i18n</li>
|
|
|
|
<li>icu/source/tools/ctestfw</li>
|
|
|
|
<li>icu/source/tools/toolutil</li>
|
|
|
|
<li>icu/source/extra/ustdio</li>
|
|
</ul>
|
|
</li>
|
|
|
|
<li>
|
|
<p>OS/390 supports both native S/390 hexadecimal floating point and,
|
|
(with Version 2.6 and later) IEEE binary floating point. This is a
|
|
compile time option. Applications built with IEEE should use ICU dlls
|
|
that are built with IEEE (and vice versa). The environment variable
|
|
IEEE390=1 will cause the OS/390 version of ICU to be built with IEEE
|
|
floating point. The default is native hexadecimal floating point.<br>
|
|
<em>Important:</em> Currently (ICU 1.4.2), native floating point
|
|
support is sufficient for codepage conversion, resource bundle and
|
|
UnicodeString operations, but the Format APIs, especially
|
|
ChoiceFormat, require IEEE binary floating point.</p>
|
|
|
|
<p>Examples for configuring ICU:<br>
|
|
Debug build: <code>IEEE390=1 ./configure</code><br>
|
|
Release build: <code>CFLAGS=-2 IEEE390=1 ./configure</code></p>
|
|
</li>
|
|
|
|
<li>Since the default make on OS/390 is not gmake, pkgdata tool
|
|
requires that the environment variable MAKE be set to fully qualified
|
|
path to gmake.</li>
|
|
|
|
<li>The makedep executable that is used with the OS/390 ICU build
|
|
process is not shipped with ICU. It is available at the <a href=
|
|
"http://www.ibm.com/servers/eserver/zseries/zos/unix/bpxa1ty1.html#opensrc">
|
|
z/OS Unix - Tools and Toys</a> site. The PATH environment variable
|
|
should be updated to contain the location of this executable prior to
|
|
build. Alternatively, makedep may be moved into an existing PATH
|
|
directory.</li>
|
|
|
|
<li>To run all of the tests for ICU, use "gmake check". When running
|
|
individual tests of the test suite, the TZ environment variable should
|
|
be set to export TZ="PST8PDT" so that time zone comparisons are
|
|
correct.</li>
|
|
</ul>
|
|
|
|
<h4><a name="HowToBuildOS390Batch">OS/390 Batch (PDS) support</a></h4>
|
|
|
|
<p>By default, ICU builds its libraries into the HFS. However, there is a
|
|
390-specific switch to build some libraries into PDS files. The switch is
|
|
the environmental variable OS390BATCH, and if set, the following
|
|
libraries are built into PDS files: libicuuc<i>XX</i>.dll,
|
|
libicudt<i>XX</i>e.dll, libicudt<i>XX</i>e_390.dll, and libtestdata.dll.
|
|
Turning on OS390BATCH does not turn off the normal HFS build, thus the
|
|
HFS dlls will always be created.</p>
|
|
|
|
<p>The names of the PDS files are determined by the value of the
|
|
environmental variables LOADMOD and LOADEXP. These variables must contain
|
|
the target PDS names whenever the OS390BATCH variable is set. LOADMOD is
|
|
the library (.dll) target dataset and LOADEXP is the side deck (.x)
|
|
target dataset.</p>
|
|
|
|
<p>The PDS member names are as follows:</p>
|
|
|
|
<div class="indent">
|
|
<pre>
|
|
IXMICUUC --> libicuuc<i>XX</i>.dll
|
|
IXMICUDA --> libicudt<i>XX</i>e.dll
|
|
IXMICUD1 --> libicudt<i>XX</i>e_390.dll
|
|
IXMICUTE --> libtestdata.dll
|
|
</pre>
|
|
</div>
|
|

<h3><a name="HowToBuildOS400">OS/400 (iSeries) Platform</a></h3>
|
|
|
|
<p>ICU Reference Release 1.8.1 contains partial support for the 400
|
|
platform, but additional work by the user is currently needed to get it
|
|
to build properly. A future release of ICU should work out-of-the-box
|
|
under OS/400.</p>
|
|
|
|
<ul>
|
|
<li>
|
|
Requirements:
|
|
|
|
<ul>
|
|
<li>QSHELL interpreter installed (install base option 30, operating
|
|
system)</li>
|
|
|
|
<li>QShell Utilities, PRPQ 5799-XEH (not required for V4R5)</li>
|
|
|
|
<li>ILE C++ for AS/400, PRPQ 5799-GDW (the latest cum package and
|
|
PTF SF62241 must be installed)</li>
|
|
|
|
<li>GNU facilities (You can get the GNU facilities for OS/400 from
|
|
<a href=
|
|
"http://www.as400.ibm.com/developer/porting/gnu_utilities.html">http://www.as400.ibm.com/developer/porting/gnu_utilities.html</a>).</li>
|
|
</ul>
|
|
<!-- end requirements -->
|
|
</li>
|
|
|
|
<li>
|
|
Build environment setup:
|
|
|
|
<ol>
|
|
<li>
|
|
Create AS400 target library. This library will be the target for
|
|
the resulting modules, programs and service programs. You will
|
|
specify this library on the OUTPUTDIR environment variable in
|
|
step 2.<br>
|
|
|
|
<div class="indent">
|
|
CRTLIB LIB(<i>libraryname</i>)
|
|
</div>
|
|
<br>
|
|
</li>
|
|
|
|
<li>
|
|
Set up the following environment variables in your build process
|
|
(use the <i>libraryname</i> from the previous step)
|
|
|
|
<div class="indent">
|
|
ADDENVVAR ENVVAR(ICU_DATA) VALUE('/icu/source/data')<br>
|
|
ADDENVVAR ENVVAR(CC) VALUE('/usr/bin/icc')<br>
|
|
ADDENVVAR ENVVAR(CXX) VALUE('/usr/bin/icc')<br>
|
|
ADDENVVAR ENVVAR(MAKE) VALUE('/usr/bin/gmake')<br>
|
|
ADDENVVAR ENVVAR(OUTPUTDIR) VALUE('<i>libraryname</i>')
|
|
<i>identifies target as400 library for *module, *pgm and
|
|
*srvpgm objects</i>
|
|
</div>
|
|
<br>
|
|
</li>
|
|
|
|
<li>Add QCXXN, to your build process library list. This results in
|
|
the resolution of CRTCPPMOD used by the icc compiler</li>
|
|
|
|
<li>
|
|
In order to get the tests to run correctly, the QUTCOFFSET needs
|
|
to be set to the Pacific Time Zone offset.<br>
|
|
<br>
|
|
To check your QUTCOFFSET:
|
|
|
|
<div class="indent">
|
|
DSPSYSVAL SYSVAL(QUTCOFFSET)
|
|
</div>
|
|
<br>
|
|
To change your QUTCOFFSET:<br>
|
|
|
|
<div class="indent">
|
|
CHGSYSVAL SYSVAL(QUTCOFFSET) VALUE('-0700')
|
|
</div>
|
|
<br>
|
|
</li>
|
|
|
|
<li>Run 'CHGJOB CCSID(37)'</li>
|
|
|
|
<li>Run 'QSH'</li>
|
|
|
|
<li>Run gunzip on the ICU source code compressed tar archive
|
|
(icu-<i>X</i>-<i>Y</i>.tar.gz or icu-<i>X</i>-<i>Y</i>.tgz).</li>
|
|
|
|
<li>Run unpax-icu.sh on the tar file from the ICU download
|
|
page.</li>
|
|
|
|
<li>Change your current directory to icu/source.</li>
|
|
|
|
<li>
|
|
Configure the Makefiles with the as/400 configure script from the
|
|
ICU download page. <strong>Note:</strong> Verify that the
|
|
mh-os400 configure file is used.
|
|
|
|
<ul>
|
|
<li>Run 'configure --host=as400-os400'</li>
|
|
|
|
<li>The 'clean' and 'install' targets will not work without
|
|
changes because of symbolic links. To delete the target module,
|
|
program, or service programs replace <tt>rm -rf</tt> with
|
|
<strong>$(RMV)</strong>, and in the library installation
|
|
targets (install-library) change <tt>$(INSTALL)</tt> to
|
|
<strong><tt>$(INSTALL-S)</tt></strong>.</li>
|
|
</ul>
|
|
</li>
|
|
|
|
<li>Run 'gmake -e'. The '-e' option is needed to pickup the
|
|
compilers.</li>
|
|
|
|
<li>Run 'gmake -e check' to run the tests.</li>
|
|
</ol>
|
|
<!-- end build environment -->

<h2><a name="ImportantNotes">Important Notes About Using ICU</a></h2>
|
|
|
|
<h3><a name="ImportantNotesWindows">Windows Platform</a></h3>
|
|
|
|
<p>If you are building on the Win32 platform, it is important that you
|
|
understand a few build details:</p>
|
|
|
|
<p><u>DLL directories and the PATH setting:</u> As delivered, the
|
|
International Components for Unicode build as several DLLs. These DLLs
|
|
are placed in the "icu\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><u>To change your PATH:</u></p>
|
|
|
|
<ul type="disk">
|
|
<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
|
|
";$Root\bin" to the end of the path string. If there is nothing there,
|
|
just type in "$Root\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 ";$Root\bin" at the
|
|
end of the path string. If there is nothing there, just type in
|
|
"$Root\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%;$Root\bin"</li>
|
|
</ul>
|
|
|
|
<p><u>Link with Runtime libraries:</u> All the DLLs link with the C
|
|
runtime library "Debug Multithreaded DLL" or "Multithreaded DLL." (This
|
|
is changed through the Project Settings dialog, on the C/C++ tab, under
|
|
Code Generation.) It is important that any executable or other DLL you
|
|
build which uses the International Components for Unicode DLLs links with
|
|
these runtime libraries as well. If you do not do this, you will
|
|
seemingly get memory errors when you run the executable.<br>
|
|
</p>
|
|
|
|
<h3><a name="sharedLibNote">Using Shared Data Libraries</a></h3>
|
|
|
|
<p>HP/UX has a documented characteristic where the shl_unload() function
|
|
always unloads a library, regardless of how many times the library has
|
|
been loaded. Most operating systems reference count libraries as they are
|
|
opened. In the future (Jitterbug 414) this may be corrected in ICU, but
|
|
at present, we work around this problem by simply NOT ever unloading
|
|
shared libraries. This means that once a data library is loaded (ex:
|
|
libicudata.sl) by a process, it cannot be unloaded and replaced without
|
|
stopping and restarting the process.</p>
