< 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 > UnicodeString supporting the Unicode 3.0 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 >
2001-03-01 04:14:40 +00:00
< li > Over 160 locales supported. Visit the < a href =

< p > There are two ways to download the ICU releases,< / p >
< ul type = "disc" >
2000-10-03 19:21:46 +00:00
< li > < strong > Official Release Snapshot:< / strong > < br >
2001-03-01 04:14:40 +00:00
If you want to use ICU (as opposed to developing it), you should
download an official packaged version of the ICU source code.
2000-10-03 19:21:46 +00:00
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 =
2000-12-14 01:22:13 +00:00
"http://oss.software.ibm.com/icu/download/">http://oss.software.ibm.com/icu/download/< / a > .< br >
2000-10-03 03:11:28 +00:00
2001-03-01 04:14:40 +00:00
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 >
2000-10-03 03:11:28 +00:00
2000-10-03 19:21:46 +00:00
< 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
2000-10-03 03:11:28 +00:00
repository to ensure that you have the most recent version of all of
the files. There are several ways to do this:< / li >
< li style = "list-style: none" >
< 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
2001-05-07 22:31:10 +00:00
example instruction on how to download ICU via WinCVS:
2000-10-03 03:11:28 +00:00
< 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 >

the correct version independent *.lib file when you have more than one
version of ICU built on your machine. Each *.lib file references its
correct version dependent shared library. The libraries with debug
information contain a "d" on the end of the base DLL name (e.g. icuuc.lib

Encoding considerations: The source code assumes that it is compiled
2001-03-01 04:14:40 +00:00
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. Those files are:
2000-10-03 03:11:28 +00:00

< 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
2000-10-03 03:11:28 +00:00
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

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 >
< pre >
IXMICUUC --> libicuuc< i > XX< / i > .dll
IXMICUDA --> libicudt< i > XX< / i > e.dll
IXMICUD1 --> libicudt< i > XX< / i > e_390.dll

< 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 ($Root) directory (you may but don't
need to place "icu" into another directory). If you change the root,
you will change the project settings accordingly in EACH makefile in
the project, updating the "include" and "library" paths.< / li >
< li > Set the environment variable < strong > ICU_DATA< / strong > to the full
pathname of the data directory. The trailing "\" is required after the
2001-01-03 02:45:24 +00:00
directory name (e.g. "$Root\source\data\" will work, but the value
"$Root\source\data" is not acceptable). This environment variable
2001-03-01 04:14:40 +00:00
indicates where the locale data files and conversion mapping tables are
located.< / li >

< li > Set the < strong > TZ< / strong > environment variable to
< strong > PST8PDT< / strong > . The tests will not work in any other

< 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 note below).< / li >
< li > Choose the "Build" menu and select "Rebuild All". 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.< / 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.< / li >

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

< 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 >
