Today's software market is a global one in which it is desirable to
|
|
Packit |
85c618 |
develop and maintain one application (single source/single binary) that
|
|
Packit |
85c618 |
supports a wide variety of languages. The International Components for
|
|
Packit |
85c618 |
Unicode (ICU) libraries provide robust and full-featured Unicode services on
|
|
Packit |
85c618 |
a wide variety of platforms to help this design goal. The ICU libraries

ICU has a sister project ICU4J that extends the internationalization
|
|
Packit |
85c618 |
capabilities of Java to a level similar to ICU. The ICU C/C++ project is also
|
|
Packit |
85c618 |
called ICU4C when a distinction is necessary.

ICU 57: Changes related to new CLDR data and specifications
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Time formats may include the new day period characters b, B, and
|
|
Packit |
85c618 |
these may produced in response to the new skeleton character C used
|
|
Packit |
85c618 |
with DateTimePatternGenerator.
|
|
Packit |
85c618 |
In day period rules, the use of "after" has been deprecated.
|
|
Packit |
85c618 |
The measurement unit "proportion-karat" has been renamed to
|
|
Packit |
85c618 |
"concentr-karat".
|
|
Packit |

Packit |
85c618 |
ICU 56: COLON withdrawn as date/time pattern character
|
|
Packit |
85c618 |
In ICU 55, COLON was introduced as a date/time pattern character
|
|
Packit |
85c618 |
to be replaced by the value of the timeSeparator for the number
|
|
Packit |
85c618 |
system being used; a corresponding new UDateFormatField
|
|
Packit |
85c618 |
UDAT_TIME_SEPARATOR_FIELD was added. Use of COLON caused some
|
|
Packit |
85c618 |
backwards compatibility problems, so it is being withdrawn as a
|
|
Packit |
85c618 |
pattern character. However, UDAT_TIME_SEPARATOR_FIELD remains
|
|
Packit |
85c618 |
as does the mechanism for replacing a pattern character with the
|
|
Packit |
85c618 |
value of the timeSeparator; a new pattern character may be
|
|
Packit |
85c618 |
assigned in the future.

ICU 56: ICU Plugins are disabled by default
|
|
Packit |
85c618 |
ICU Plugins are now disabled by default. They may be enabled
|
|
Packit |
85c618 |
with the configure option
|
|
Packit |
85c618 |
<tt>--enable-plugins</tt> or by means of
|
|
Packit |
85c618 |
<tt>#define UCONFIG_ENABLE_PLUGINS</tt>.

ICU 55: Layout Engine breaking API change
|
|
Packit |
85c618 |
The LayoutEngine (already deprecated) has had the function
|
|
Packit |
85c618 |
<tt>LEFontInstance::getFontTable(LETag, size_t &length)</tt>
|
|
Packit |
85c618 |
since ICU 52. Its implementation was optional. In ICU 55, this
|
|
Packit |
85c618 |
version
|
|
Packit |
85c618 |
of <tt>getFontTable</tt> has been made pure virtual, and the
|
|
Packit |
85c618 |
version without a length (<tt>getFontTable(LETag)</tt>) has been
|
|
Packit |
85c618 |
completely removed. This is a breaking change for users who have
|
|
Packit |
85c618 |
not implemented the two-argument <tt>getFontTable()</tt>
|
|
Packit |
85c618 |
function in their <tt>LEFontInstance</tt> subclasses.
|
|
Packit |
85c618 |
The break is intentional, as the one-argument version cannot be
|
|
Packit |
85c618 |
made secure. See <tt>LEFontInstance</tt> api docs for more detail.

ICU 55: Deprecations in PluralRules (plurrule.h)
|
|
Packit |
85c618 |
The following PluralRules methods never had an implementation
|
|
Packit |
85c618 |
but were inadvertently marked @stable; they have now been
|
|
Packit |
85c618 |
deprecated. [#10759]
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
<tt>double icu::PluralRules::getUniqueKeywordValue(const UnicodeString&)</tt>

ICU 55: Deprecate uidna.h functions for IDNA2003 support
|
|
Packit |
85c618 |
The IDNA2003 API has been deprecated; use the API for IDNA2008 / UTS #46 instead via
|
|
Packit |
85c618 |
uidna_openUTS46() or class IDNA [#8477].

ICU 54: Deprecation of Layout Engine
|
|
Packit |
85c618 |
The LayoutEngine is now deprecated. Please
|
|
Packit |
85c618 |
see the
|
|
Packit |
85c618 |
User's Guide for more details and migration recommendations.
|
|
Packit |
85c618 |
In the future, passing "<tt>--enable-layout</tt>" to configure
|
|
Packit |
85c618 |
will be required to
|
|
Packit |
85c618 |
enable the layout engine.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Note that the ParagraphLayout (layoutex) library is not deprecated.
|
|
Packit |
85c618 |
There is a new option, <tt>--enable-layoutex</tt> which will build
|
|
Packit |
85c618 |
the ParagraphLayout library using HarfBuzz
|
|
Packit |
85c618 |
instead of ICU as the layout engine. See
|
|
Packit |
85c618 |
the users' guide for more information about how to build.

ICU 54: Deprecation of Collation Short Strings
|
|
Packit |
85c618 |
The collation short naming scheme and its API functions are deprecated.
|
|
Packit |
85c618 |
Use ucol_open() with language tag collation keywords instead (see Collation API Details). For example, ucol_open("de-u-co-phonebk-ka-shifted", &errorCode)
|
|
Packit |
85c618 |
for German Phonebook order with "ignore punctuation" mode.

ICU 54: Deprecation of UCOL_TAILORINGS_VERSION
|
|
Packit |
85c618 |
This was originally intended to be the version of collation tailorings,
|
|
Packit |
85c618 |
but that information is actually in the tailorings data and this
|
|
Packit |
85c618 |
constant has always been (and now will continue to be) 1.

ICU 53: Deprecation of TimeUnitFormat
|
|
Packit |
85c618 |
The TimeUnitFormat and its methods were actually deprecated in ICU 53 and the
|
|
Packit |
85c618 |
class as a whole was tagged as deprecated in that release, but the status tags for
|
|
Packit |
85c618 |
the individual methods did not correctly indicate the deprecated status; they
|
|
Packit |
85c618 |
do as of ICU 54. Use the MeasureFormat class and its methods instead.

Official Release Snapshot:
|
|
Packit |
85c618 |
If you want to use ICU (as opposed to developing it), you should download
|
|
Packit |
85c618 |
an official packaged version of the ICU source code. These versions are
|
|
Packit |
85c618 |
tested more thoroughly than day-to-day development builds of the system,
|
|
Packit |
85c618 |
and they are packaged in zip and tar files for convenient download. These
|
|
Packit |
85c618 |
packaged files can be found at
|
|
Packit |
85c618 |
"http://site.icu-project.org/download">http://site.icu-project.org/download.
|
|
Packit |
85c618 |
The packaged snapshots are named icu-nnnn.zip or
|
|
Packit |
85c618 |
icu-nnnn.tgz, where nnnn is the version number. The .zip
|
|
Packit |
85c618 |
file is used for Windows platforms, while the .tgz file is preferred on
|
|
Packit |
85c618 |
most other platforms.

|
|
Packit |
85c618 |
If you are interested in developing features, patches, or bug fixes for
|
|
Packit |
85c618 |
ICU, you should probably be working with the latest version of the ICU
|
|
Packit |
85c618 |
source code. You will need to check the code out of our Subversion repository to
|
|
Packit |
85c618 |
ensure that you have the most recent version of all of the files. See our

85c618 |
|
|
Packit |
85c618 |
Depending on the platform and the type of installation,
|
|
Packit |
85c618 |
we recommend a small number of modifications and build options.
|
|
Packit |
85c618 |
Note that C99 compatibility is now required.

|
Packit |
85c618 |

Namespace: By default, unicode/uversion.h has
|
|
Packit |
85c618 |
"using namespace icu;" which defeats much of the purpose of the namespace.
|
|
Packit |
85c618 |
(This is for historical reasons: Originally, ICU4C did not use namespaces,
|
|
Packit |
85c618 |
and some compilers did not support them. The default "using" statement
|
|
Packit |
85c618 |
preserves source code compatibility.)
|
|
Packit |
85c618 |
If this compatibility is not an issue, we recommend you turn this off
|
|
Packit |
85c618 |
via -DU_USING_ICU_NAMESPACE=0

Packit |
85c618 |
like MacOS X and some Linux distributions,

Packit |
85c618 |
we recommend hardcoding ICU's default charset to UTF-8.
|
|
Packit |
85c618 |
This means that some implementation code becomes simpler and faster,
|
|
Packit |
85c618 |
and statically linked ICU libraries become smaller.

UnicodeString constructors: The UnicodeString class has
|
|
Packit |
85c618 |
several single-argument constructors that are not marked "explicit"
|
|
Packit |
85c618 |
for historical reasons.
|
|
Packit |
85c618 |
This can lead to inadvertent construction of a UnicodeString
|
|
Packit |
85c618 |
with a single character by using an integer,
|
|
Packit |
85c618 |
and it can lead to inadvertent dependency on the conversion framework
|
|
Packit |
85c618 |
by using a C string literal.
|
|
Packit |
85c618 |
Beginning with ICU 49, you should do the following:
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Consider marking the from-UChar
|
|
Packit |
85c618 |
and from-UChar32 constructors explicit via
|
|
Packit |
85c618 |
-DUNISTR_FROM_CHAR_EXPLICIT=explicit or similar.
|
|
Packit |
85c618 |
Consider marking the from-const char* and
|
|
Packit |
85c618 |
from-const UChar* constructors explicit via
|
|
Packit |
85c618 |
-DUNISTR_FROM_STRING_EXPLICIT=explicit or similar.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Note: The ICU test suites cannot be compiled with these settings.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
utf.h, utf8.h, utf16.h, utf_old.h:
|
|
Packit |
85c618 |
By default, utypes.h (and thus almost every public ICU header)
|
|
Packit |
85c618 |
includes all of these header files.
|
|
Packit |
85c618 |
Often, none of them are needed, or only one or two of them.
|
|
Packit |
85c618 |
All of utf_old.h is deprecated or obsolete.
|
|
Packit |
85c618 |
Beginning with ICU 49,
|
|
Packit |
85c618 |
you should define U_NO_DEFAULT_INCLUDE_UTF_HEADERS to 1
|
|
Packit |
85c618 |
(via -D or uconfig.h, as above)
|
|
Packit |
85c618 |
and include those header files explicitly that you actually need.
|
|
Packit |
85c618 |
Note: The ICU test suites cannot be compiled with this setting.
|
|
Packit |
85c618 |
.dat file: By default, the ICU data is built into
|
|
Packit |
85c618 |
a shared library (DLL). This is convenient because it requires no
|
|
Packit |
85c618 |
install-time or runtime configuration,
|
|
Packit |
85c618 |
but the library is platform-specific and cannot be modified.
|
|
Packit |
85c618 |
A .dat package file makes the opposite trade-off:
|
|
Packit |
85c618 |
Platform-portable (except for endianness and charset family, which
|
|
Packit |
85c618 |
can be changed with the icupkg tool)
|
|
Packit |
85c618 |
and modifiable (also with the icupkg tool).
|
|
Packit |
85c618 |
If a path is set, then single data files (e.g., .res files)
|
|
Packit |
85c618 |
can be copied to that location to provide new locale data
|
|
Packit |
85c618 |
or conversion tables etc.
|
|
Packit |
85c618 |
The only drawback with a .dat package file is that the application
|
|
Packit |
85c618 |
needs to provide ICU with the file system path to the package file
|
|
Packit |
85c618 |
(e.g., by calling u_setDataDirectory())
|
|
Packit |
85c618 |
or with a pointer to the data (udata_setCommonData())
|
|
Packit |
85c618 |
before other ICU API calls.
|
|
Packit |
85c618 |
This is usually easy if ICU is used from an application where
|
|
Packit |
85c618 |
main() takes care of such initialization.
|
|
Packit |
85c618 |
It may be hard if ICU is shipped with
|
|
Packit |
85c618 |
another shared library (such as the Xerces-C++ XML parser)
|
|
Packit |
85c618 |
which does not control main().
|
|
Packit |
85c618 |
See the User Guide ICU Data
|
|
Packit |
85c618 |
chapter for more details.
|
|
Packit |
85c618 |
If possible, we recommend building the .dat package.
|
|
Packit |
85c618 |
Specify --with-data-packaging=archive
|
|
Packit |
85c618 |
on the configure command line, as in
|
|
Packit |
85c618 |
runConfigureICU Linux --with-data-packaging=archive
|
|
Packit |
85c618 |
(Read the configure script's output for further instructions.
|
|
Packit |
85c618 |
On Windows, the Visual Studio build generates both the .dat package
|
|
Packit |
85c618 |
and the data DLL.)
|
|
Packit |
85c618 |
Be sure to install and use the tiny stubdata library
|
|
Packit |
85c618 |
rather than the large data DLL.
|
|
Packit |
85c618 |
Static libraries: It may make sense to build the ICU code
|
|
Packit |
85c618 |
into static libraries (.a) rather than shared libraries (.so/.dll).
|
|
Packit |
85c618 |
Static linking reduces the overall size of the binary by removing
|
|
Packit |
85c618 |
code that is never called.
|
|
Packit |
85c618 |
Example configure command line:
|
|
Packit |
85c618 |
runConfigureICU Linux --enable-static --disable-shared
|
|
Packit |
85c618 |
Out-of-source build: It is usually desirable to keep the ICU
|
|
Packit |
85c618 |
source file tree clean and have build output files written to
|
|
Packit |
85c618 |
a different location. This is called an "out-of-source build".
|
|
Packit |
85c618 |
Simply invoke the configure script from the target location:
|
|
Packit |
85c618 |
~/icu$ svn export http://source.icu-project.org/repos/icu/icu/trunk
|
|
Packit |
85c618 |
~/icu$ mkdir trunk-dev
|
|
Packit |
85c618 |
~/icu$ cd trunk-dev
|
|
Packit |
85c618 |
~/icu/trunk-dev$ ../trunk/source/runConfigureICU Linux
|
|
Packit |
85c618 |
~/icu/trunk-dev$ make check
|
|
Packit |
85c618 |
(Note: this example shows a relative path to
|
|
Packit |
85c618 |
runConfigureICU. If you experience difficulty,
|
|
Packit |
85c618 |
try using an absolute path to runConfigureICU
|
|
Packit |
85c618 |
instead.)

Packit |
85c618 |
ICU as a System-Level Library
|
|
Packit |
85c618 |
If ICU is installed as a system-level library, there are further
|
|
Packit |
85c618 |
opportunities and restrictions to consider.
|
|
Packit |
85c618 |
For details, see the Using ICU as an Operating System Level Library
|
|
Packit |
85c618 |
section of the User Guide ICU Architectural Design chapter.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Data path: For a system-level library, it is best to load
|
|
Packit |
85c618 |
ICU data from the .dat package file because the file system path
|
|
Packit |
85c618 |
to the .dat package file can be hardcoded. ICU will automatically set
|
|
Packit |
85c618 |
the path to the final install location using U_ICU_DATA_DEFAULT_DIR.
|
|
Packit |
85c618 |
Alternatively, you can set -DICU_DATA_DIR=/path/to/icu/data
|
|
Packit |
85c618 |
when building the ICU code. (Used by source/common/putil.c.)
|
|
Packit |
85c618 |
Consider also setting -DICU_NO_USER_DATA_OVERRIDE
|
|
Packit |
85c618 |
if you do not want the "ICU_DATA" environment variable to be used.
|
|
Packit |
85c618 |
(An application can still override the data path via
|
|
Packit |
85c618 |
u_setDataDirectory() or
|
|
Packit |
85c618 |
udata_setCommonData().
|
|
Packit |
85c618 |
Hide draft API: API marked with @draft
|
|
Packit |
85c618 |
is new and not yet stable. Applications must not rely on unstable
|
|
Packit |
85c618 |
APIs from a system-level library.
|
|
Packit |
85c618 |
Define U_HIDE_DRAFT_API, U_HIDE_INTERNAL_API
|
|
Packit |
85c618 |
and U_HIDE_SYSTEM_API
|
|
Packit |
85c618 |
by modifying unicode/utypes.h before installing it.
|
|
Packit |
85c618 |
Only C APIs: Applications must not rely on C++ APIs from a
|
|
Packit |
85c618 |
system-level library because binary C++ compatibility
|
|
Packit |
85c618 |
across library and compiler versions is very hard to achieve.
|
|
Packit |
85c618 |
Most ICU C++ APIs are in header files that contain a comment with
|
|
Packit |
85c618 |
\brief C++ API.
|
|
Packit |
85c618 |
Consider not installing these header files.
|
|
Packit |
85c618 |
Disable renaming: By default, ICU library entry point names
|
|
Packit |
85c618 |
have an ICU version suffix. Turn this off for a system-level installation,
|
|
Packit |
85c618 |
to enable upgrading ICU without breaking applications. For example:
|
|
Packit |
85c618 |
runConfigureICU Linux --disable-renaming
|
|
Packit |
85c618 |
The public header files from this configuration must be installed
|
|
Packit |
85c618 |
for applications to include and get the correct entry point names.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
ICU4C can be customized via a number of user-configurable settings.
|
|
Packit |
85c618 |
Many of them are controlled by preprocessor macros which are
|
|
Packit |
85c618 |
defined in the source/common/unicode/uconfig.h header file.
|
|
Packit |
85c618 |
Some turn off parts of ICU, for example conversion or collation,
|
|
Packit |
85c618 |
trading off a smaller library for reduced functionality.
|
|
Packit |
85c618 |
Other settings are recommended (see previous section)
|
|
Packit |
85c618 |
but their default values are set for better source code compatibility.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
In order to change such user-configurable settings, you can
|
|
Packit |
85c618 |
either modify the uconfig.h header file by adding
|
|
Packit |
85c618 |
a specific #define ... for one or more of the macros
|
|
Packit |
85c618 |
before they are first tested,
|
|
Packit |
85c618 |
or set the compiler's preprocessor flags (CPPFLAGS) to include
|
|
Packit |
85c618 |
an equivalent -D macro definition.

<ICU>\include\ and the link libraries are in
|
|
Packit |
85c618 |
<ICU>\lib\. To install the ICU runtime on a machine, or ship

There are two ways you can build ICU with Cygwin. You can build with gcc
|
|
Packit |
85c618 |
or Microsoft Visual C++. If you use gcc, the resulting libraries and tools
|
|
Packit |
85c618 |
will depend on the Cygwin environment. If you use Microsoft Visual C++, the
|
|
Packit |
85c618 |
resulting libraries and tools do not depend on Cygwin and can be more easily
|
|
Packit |
85c618 |
distributed to other Windows computers (the generated man pages and shell
|
|
Packit |
85c618 |
scripts still need Cygwin). To build with gcc, please follow the "
|
|
Packit |
85c618 |
"#HowToBuildUNIX">How To Build And Install On UNIX" instructions, while
|
|
Packit |
85c618 |
you are inside a Cygwin bash shell. To build with Microsoft Visual C++,
|
|
Packit |
85c618 |
please use the following instructions:
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Start the Windows "Command Prompt" window. This is different from the
|
|
Packit |
85c618 |
gcc build, which requires the Cygwin Bash command prompt. The Microsoft
|
|
Packit |
85c618 |
Visual C++ compiler will not work with a bash command prompt.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
If the computer isn't set up to use Visual C++ from the command line,
|
|
Packit |
85c618 |
you need to run vcvars32.bat.
For example:
"<tt>C:\Program Files\Microsoft
|
|
Packit |
85c618 |
Visual Studio 8\VC\bin\vcvars32.bat</tt>" can be used for 32-bit builds
|
|
Packit |
85c618 |
or
"<tt>C:\Program Files (x86)\Microsoft Visual Studio
|
|
Packit |
85c618 |
8\VC\bin\amd64\vcvarsamd64.bat</tt>" can be used for 64-bit builds on
|
|
Packit |
85c618 |
Windows x64.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Unzip the icu-XXXX.zip file into any convenient location. Using command
|
|
Packit |
85c618 |
line zip, type "unzip -a icu-XXXX.zip -d drive:\directory", or just use
|
|
Packit |
85c618 |
WinZip.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Change directory to "icu/source", which is where you unzipped ICU.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Run "<tt>bash ./runConfigureICU

Packit |
85c618 |
|
|
Packit |
85c618 |
Type <tt>"make"</tt> to compile the libraries and all the data files.

Here are the steps to build ICU:
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Decompress the icu-X.Y.tgz (or
|
|
Packit |
85c618 |
icu-X.Y.tar.gz) file. For example, <samp>gunzip -d < icu-X.Y.tgz | tar xvf -</samp>
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Change directory to icu/source.
|
|
Packit |
85c618 |
<samp>cd icu/source</samp>
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Some files may have the wrong permissions.<samp>chmod +x runConfigureICU configure install-sh</samp>
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Run the runConfigureICU
|
|
Packit |
85c618 |
script for your platform. (See configuration
|
|
Packit |
85c618 |
note below).
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Now build: <samp>gmake</samp> (or just make if GNU make is the default make on
|
|
Packit |
85c618 |
your platform) to compile the libraries and all the data files. The proper
|
|
Packit |
85c618 |
name of the GNU make command is printed at the end of the configuration
|
|
Packit |
85c618 |
run, as in <tt>"You must use gmake to compile ICU"</tt>.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Note that the compilation command output may be simplified on your platform. If this is the case, you will see just:
|
|
Packit |
85c618 |
<tt>gcc ... stubdata.c</tt>
|
|
Packit |
85c618 |
rather than
|
|
Packit |
85c618 |
<tt>gcc -DU_NO_DEFAULT_INCLUDE_UTF_HEADERS=1 -D_REENTRANT -I../common -DU_ATTRIBUTE_DEPRECATED= -O2 -Wall -std=c99 -pedantic -Wshadow -Wpointer-arith -Wmissing-prototypes -Wwrite-strings -c -DPIC -fPIC -o stubdata.o stubdata.c</tt>
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
If you need to see the whole compilation line, use "gmake VERBOSE=1". The full compilation line will print if an error occurs.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Optionally,<samp>gmake check</samp> will run the test suite, which
|
|
Packit |
85c618 |
checks for ICU's functionality integrity (See
|
|
Packit |
85c618 |
"#HowToTestWithoutGmake">testing note below).
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
To install, <samp>gmake install</samp> to install ICU. If you used the --prefix=
|
|
Packit |
85c618 |
option on configure or runConfigureICU, ICU will be installed to the
|
|
Packit |
85c618 |

ICU is built with strict compiler warnings enabled by default. If this
|
|
Packit |
85c618 |
causes excessive numbers of warnings on your platform, use the --disable-strict
|
|
Packit |
85c618 |
option to configure to reduce the warning level.

The Tests From The Command Line NOTE: You may have to set
|
|
Packit |
85c618 |
certain variables if you with to run test programs individually, that is
|
|
Packit |
85c618 |
apart from "gmake check". The environment variable ICU_DATA
|
|
Packit |
85c618 |
can be set to the full pathname of the data directory to indicate where the
|
|
Packit |
85c618 |
locale data files and conversion mapping tables are when you are not using
|
|
Packit |
85c618 |
the shared library (e.g. by using the .dat archive or the individual data
|
|
Packit |
85c618 |
files). The trailing "/" is required after the directory name (e.g.
|
|
Packit |
85c618 |
"$Root/source/data/out/" will work, but the value "$Root/source/data/out" is
|
|
Packit |
85c618 |
not acceptable). You do not need to set ICU_DATA if the
|
|
Packit |
85c618 |
complete shared data library is in your library path.

Installing ICU
|
|
Packit |
85c618 |
NOTE: Some platforms use package management tools to control the
|
|
Packit |
85c618 |
installation and uninstallation of files on the system, as well as the
|
|
Packit |
85c618 |
integrity of the system configuration. You may want to check if ICU can be
|
|
Packit |
85c618 |
packaged for your package management tools by looking into the "packaging"
|
|
Packit |
85c618 |
directory. (Please note that if you are using a snapshot of ICU from Subversion, it
|
|
Packit |
85c618 |
is probable that the packaging scripts or related files are not up to date
|
|
Packit |
85c618 |
with the contents of ICU at this time, so use them with caution).

Build And Install On z/OS (OS/390)
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
You can install ICU on z/OS or OS/390 (the previous name of z/OS), but IBM
|
|
Packit |
85c618 |
tests only the z/OS installation. You install ICU in a z/OS UNIX system
|
|
Packit |
85c618 |
services file system such as HFS or zFS. On this platform, it is important
|
|
Packit |
85c618 |
that you understand a few details:
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
The makedep and GNU make tools are required for building ICU. If it
|
|
Packit |
85c618 |
is not already installed on your system, it is available at the
|
|
Packit |
85c618 |
"http://www-03.ibm.com/servers/eserver/zseries/zos/unix/bpxa1toy.html">z/OS UNIX -
|
|
Packit |
85c618 |
Tools and Toys site. The PATH environment variable should be updated to
|
|
Packit |
85c618 |
contain the location of this executable prior to build. Failure to add these
|
|
Packit |
85c618 |
tools to your PATH will cause ICU build failures or cause pkgdata to fail
|
|
Packit |
85c618 |
to run.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Since USS does not support using the mmap() function over NFS, it is
|
|
Packit |
85c618 |
recommended that you build ICU on a local filesystem. Once ICU has been
|
|
Packit |
85c618 |
built, you should not have this problem while using ICU when the data
|
|
Packit |
85c618 |
library has been built as a shared library, which is this is the default
|
|
Packit |
85c618 |
setting.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Encoding considerations: The source code assumes that it is compiled
|
|
Packit |
85c618 |
with codepage ibm-1047 (to be exact, the UNIX System Services variant of
|
|
Packit |
85c618 |
it). The pax command converts all of the source code files from ASCII to
|
|
Packit |
85c618 |
codepage ibm-1047 (USS) EBCDIC. However, some files are binary files and
|
|
Packit |
85c618 |
must not be converted, or must be converted back to their original state.
|
|
Packit |
85c618 |
You can use the unpax-icu.sh script
|
|
Packit |
85c618 |
to do this for you automatically. It will unpackage the tar file and
|
|
Packit |
85c618 |
convert all the necessary files for you automatically.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
z/OS supports both native S/390 hexadecimal floating point and (with
|
|
Packit |
85c618 |
OS/390 2.6 and later) IEEE 754 binary floating point. This is a compile
|
|
Packit |
85c618 |
time option. Applications built with IEEE should use ICU DLLs that are
|
|
Packit |
85c618 |
built with IEEE (and vice versa). The environment variable IEEE390=0 will
|
|
Packit |
85c618 |
cause the z/OS version of ICU to be built without IEEE floating point
|
|
Packit |
85c618 |
support and use the native hexadecimal floating point. By default ICU is
|
|
Packit |
85c618 |
built with IEEE 754 support. Native floating point support is sufficient
|
|
Packit |
85c618 |
for codepage conversion, resource bundle and UnicodeString operations, but
|
|
Packit |
85c618 |
the Format APIs require IEEE binary floating point.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
z/OS introduced the concept of Extra Performance Linkage (XPLINK) to
|
|
Packit |
85c618 |
bring performance improvement opportunities to call-intensive C and C++
|
|
Packit |
85c618 |
applications such as ICU. XPLINK is enabled on a DLL-by-DLL basis, so if
|
|
Packit |
85c618 |
you are considering using XPLINK in your application that uses ICU, you
|
|
Packit |
85c618 |
should consider building the XPLINK-enabled version of ICU. You need to
|
|
Packit |
85c618 |
set ICU's environment variable OS390_XPLINK=1 prior to
|
|
Packit |
85c618 |
invoking the make process to produce binaries that are enabled for
|
|
Packit |
85c618 |
XPLINK. The XPLINK option, which is available for z/OS 1.2 and later,
|
|
Packit |
85c618 |
requires the PTF PQ69418 to build XPLINK enabled binaries.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
ICU requires XPLINK for the icuio library. If you want to use the
|
|
Packit |
85c618 |
rest of ICU without XPLINK, then you must use the --disable-icuio
|
|
Packit |
85c618 |
configure option.

environment
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
By default, ICU builds its libraries into the UNIX file system (HFS). In
|
|
Packit |
85c618 |
addition, there is a z/OS specific environment variable (OS390BATCH) to build
|
|
Packit |
85c618 |
some libraries into the z/OS native file system. This is useful, for example,
|
|
Packit |
85c618 |
when your application is externalized via Job Control Language (JCL).
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
The OS390BATCH environment variable enables non-UNIX support including the
|
|
Packit |
85c618 |
batch environment. When OS390BATCH is set, the libicui18nXX.dll,
|
|
Packit |
85c618 |
libicuucXX.dll, and libicudtXXe.dll binaries are built into
|
|
Packit |
85c618 |
data sets (the native file system). Turning on OS390BATCH does not turn off
|
|
Packit |
85c618 |
the normal z/OS UNIX build. This means that the z/OS UNIX (HFS) DLLs will
|
|
Packit |
85c618 |
always be created.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Two additional environment variables indicate the names of the z/OS data
|
|
Packit |
85c618 |
sets to use. The LOADMOD environment variable identifies the name of the data
|
|
Packit |
85c618 |
set that contains the dynamic link libraries (DLLs) and the LOADEXP
|
|
Packit |
85c618 |
environment variable identifies the name of the data set that contains the
|
|
Packit |
85c618 |
side decks, which are normally the files with the .x suffix in the UNIX file
|
|
Packit |
85c618 |
system.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
A data set is roughly equivalent to a UNIX or Windows file. For most kinds
|
|
Packit |
85c618 |
of data sets the operating system maintains record boundaries. UNIX and
|
|
Packit |
85c618 |
Windows files are byte streams. Two kinds of data sets are PDS and PDSE. Each
|
|
Packit |
85c618 |
data set of these two types contains a directory. It is like a UNIX
|
|
Packit |
85c618 |
directory. Each "file" is called a "member". Each member name is limited to
|
|
Packit |
85c618 |
eight bytes, normally EBCDIC.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Here is an example of some environment variables that you can set prior to
|
|
Packit |
85c618 |
building ICU:
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
<samp>OS390BATCH=1
|

|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
The PDS member names for the DLL file names are as follows:
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
<samp>IXMIXXIN --> libicui18nXX.dll
|
|

|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
You should point the LOADMOD environment variable at a partitioned data
|
|
Packit |
85c618 |
set extended (PDSE) and point the LOADEXP environment variable at a
|
|
Packit |
85c618 |
partitioned data set (PDS). The PDSE can be allocated with the following

This section will explain how to build ICU on one platform, but to produce binaries intended to run on another. This is commonly known as a cross compile.
|
|
Packit |
85c618 |
Normally, in the course of a build, ICU needs to run the tools that it builds in order to generate and package data and test-data.In a cross compilation setting, ICU is built on a different system from that which it eventually runs on. An example might be, if you are building for a small/headless system (such as an embedded device), or a system where you can't easily run the ICU command line tools (any non-UNIX-like system).
|
|
Packit |
85c618 |
To reduce confusion, we will here refer to the "A" and the "B" system.System "A" is the actual system we will be running on- the only requirements on it is are it is able to build ICU from the command line targetting itself (with configure or runConfigureICU), and secondly, that it also contain the correct toolchain for compiling and linking for the resultant platform, referred to as the "B" system.
|
|
Packit |
85c618 |
The autoconf docs use the term "build" for A, and "host" for B. More details at: http://www.gnu.org/software/autoconf/manual/html_node/Specifying-Names.html
|
|
Packit |
85c618 |
Three initially-empty directories will be used in this example:
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
|
|
Packit |

|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
/buildAan empty directory, it will contain ICU built for A
(MacOSX in this case)
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
/buildBan empty directory, it will contain ICU built for B
(HaikuOS in this case)

Packit |
85c618 |
Check out or unpack the ICU source code into the /icu directory.You will have the directories /icu/source, etc.
|
|
Packit |
85c618 |
Build ICU in /buildA normally (using runConfigureICU or configure):
|
|
Packit |
85c618 |
cd /buildA
|
|
Packit |
85c618 |
sh /icu/source/runConfigureICU MacOSX
|
|
Packit |
85c618 |

|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Set PATH or other variables as needed, such as CPPFLAGS.
|
|
Packit |
85c618 |
Build ICU in /buildB
|
|
Packit |
85c618 |
"--with-cross-build" takes an absolute path.
|
|
Packit |
85c618 |
cd /buildB
|
|
Packit |
85c618 |
sh /icu/source/configure --host=i586-pc-haiku --with-cross-build=/buildA

85c618 |
gnumake
|
|
Packit |

Package ICU
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
There are many ways that a person can package ICU with their software
|
|
Packit |
85c618 |
products. Usually only the libraries need to be considered for packaging.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
On UNIX, you should use "<tt>gmake install</tt>" to make it easier to
|
|
Packit |
85c618 |
develop and package ICU. The bin, lib and include directories are needed to
|
|
Packit |
85c618 |
develop applications that use ICU. These directories will be created relative
|
|
Packit |
85c618 |
to the "<tt>--prefix=</tt>dir" configure option (See the
|
|
Packit |
85c618 |
"#HowToBuildUNIX">UNIX build instructions). When ICU is built on Windows,
|
|
Packit |
85c618 |
a similar directory structure is built.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
When changes have been made to the standard ICU distribution, it is
|
|
Packit |
85c618 |
recommended that at least one of the following guidelines be followed for
|
|
Packit |
85c618 |
special packaging.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Add a suffix name to the library names. This can be done with the
|
|
Packit |
85c618 |
--with-library-suffix configure option.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
The installation script should install the ICU libraries into the
|
|
Packit |
85c618 |
application's directory.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Following these guidelines prevents other applications that use a standard
|
|
Packit |
85c618 |
ICU distribution from conflicting with any libraries that you need. On
|
|
Packit |
85c618 |
operating systems that do not have a standard C++ ABI (name mangling) for
|
|
Packit |
85c618 |
compilers, it is recommended to do this special packaging anyway. More
|
|
Packit |

Normally only the above ICU libraries need to be considered for packaging.
|
|
Packit |
85c618 |
The versionless symbolic links to these libraries are only needed for easier
|
|
Packit |
85c618 |
development. The X, Y and Z parts of the name are the
|
|
Packit |
85c618 |
version numbers of ICU. For example, ICU 2.0.2 would have the name
|
|
Packit |
85c618 |
libicuuc.so.20.2 for the common library. The exact format of the library
|
|
Packit |
85c618 |
names can vary between platforms due to how each platform can handles library
|
|
Packit |
85c618 |
versioning.

85c618 |
Environment
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Some versions of ICU require calling the u_init() function
|
|
Packit |
85c618 |
from uclean.h to ensure that ICU is initialized properly. In
|
|
Packit |
85c618 |
those ICU versions, u_init() must be called before ICU is used
|
|
Packit |
85c618 |
from multiple threads. There is no harm in calling u_init() in a
|
|
Packit |
85c618 |
single-threaded application, on a single-CPU machine, or in other cases where
|
|
Packit |
85c618 |
u_init() is not required.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
In addition to ensuring thread safety, u_init() also attempts
|
|
Packit |
85c618 |
to load at least one ICU data file. Assuming that all data files are packaged
|
|
Packit |
85c618 |
together (or are in the same folder in files mode), a failure code from
|
|
Packit |
85c618 |
u_init() usually means that the data cannot be found. In this
|
|
Packit |
85c618 |
case, the data may not be installed properly, or the application may have
|
|
Packit |
85c618 |
failed to call udata_setCommonData() or
|
|
Packit |
85c618 |
u_setDataDirectory() which specify to ICU where it can find its
|
|
Packit |
85c618 |
data.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Since u_init() will load only one or two data files, it
|
|
Packit |
85c618 |
cannot guarantee that all of the data that an application needs is available.
|
|
Packit |
85c618 |
It cannot check for all data files because the set of files is customizable,
|
|
Packit |
85c618 |
and some ICU services work without loading any data at all. An application
|
|
Packit |
85c618 |
should always check for error codes when opening ICU service objects (using
|
|
Packit |
85c618 |
ucnv_open(), ucol_open(), C++ constructors,
|
|
Packit |
85c618 |
etc.).

ICU 3.4 and later
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
ICU 3.4 self-initializes properly for multi-threaded use. It achieves this
|
|
Packit |
85c618 |
without performance penalty by hardcoding the core Unicode properties data,
|
|
Packit |
85c618 |
at the cost of some flexibility. (For details see Jitterbug 4497.)
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
u_init() can be used to check for data loading. It tries to
|
|
Packit |
85c618 |
load the converter alias table (cnvalias.icu).
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
ICU 2.6..3.2
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
These ICU versions require a call to u_init() before
|
|
Packit |
85c618 |
multi-threaded use. The services that are directly affected are those that
|
|
Packit |
85c618 |
don't have a service object and need to be fast: normalization and character
|
|
Packit |
85c618 |
properties.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
u_init() loads and initializes the data files for
|
|
Packit |
85c618 |
normalization and character properties (unorm.icu and
|
|
Packit |
85c618 |
uprops.icu) and can therefore also be used to check for data
|
|
Packit |
85c618 |
loading.

ICU 2.4 and earlier
|
|
Packit |

ICU 2.4 and earlier versions were not prepared for multithreaded use on
|
|
Packit |
85c618 |
multi-CPU platforms where the CPUs implement weak memory coherency. These
|
|
Packit |
85c618 |
CPUs include: Power4, Power5, Alpha, Itanium. u_init() was not

Packit |
85c618 |
guidelines for multithreaded applications, specified in the following

|
Packit |
85c618 |
following statements from Sun:
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
To use libthread, specify -lthread before -lc on the ld command line, or
|
|
Packit |
85c618 |
last on the cc command line.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
To use libpthread, specify -lpthread before -lc on the ld command line,
|
|
Packit |
85c618 |
or last on the cc command line.

Packit |
85c618 |

85c618 |
If you are building on the Win32 platform, it is important that you
|
|
Packit |
85c618 |
understand a few of the following build details.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
DLL directories and the PATH setting
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
As delivered, the International Components for Unicode build as several
|
|
Packit |
85c618 |
DLLs, which are placed in the "<ICU>\bin" directory. You must
|
|
Packit |
85c618 |
add this directory to the PATH environment variable in your system, or any
|
|
Packit |
85c618 |
executables you build will not be able to access International Components for
|
|
Packit |
85c618 |
Unicode libraries. Alternatively, you can copy the DLL files into a directory
|
|
Packit |
85c618 |
already in your PATH, but we do not recommend this. You can wind up with
|
|
Packit |
85c618 |
multiple copies of the DLL and wind up using the wrong one.

85c618 |
Windows 2000/XP: Use the System Icon in the Control
|
|
Packit |
85c618 |
Panel. Pick the "Advanced" tab. Select the "Environment Variables..."
|
|
Packit |
85c618 |
button. Select the variable PATH in the lower box, and select the lower
|
|
Packit |
85c618 |
"Edit..." button. In the "Variable Value" box, append the string
|
|
Packit |
85c618 |
";<ICU>\bin" to the end of the path string. If there is
|
|
Packit |
85c618 |
nothing there, just type in "<ICU>\bin". Click the Set button,
|
|
Packit |
85c618 |
then the OK button.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Note: When packaging a Windows application for distribution and
|
|
Packit |
85c618 |
installation on user systems, copies of the ICU DLLs should be included with
|
|
Packit |
85c618 |
the application, and installed for exclusive use by the application. This is
|
|
Packit |
85c618 |
the only way to insure that your application is running with the same version
|
|
Packit |
85c618 |
of ICU, built with exactly the same options, that you developed and tested
|
|
Packit |
85c618 |
with. Refer to Microsoft's guidelines on the usage of DLLs, or search for the
|

"ImportantNotesUNIX">UNIX Type Platform
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
If you are building on a UNIX platform, and if you are installing ICU in a
|
|
Packit |
85c618 |
non-standard location, you may need to add the location of your ICU libraries
|
|
Packit |
85c618 |
to your LD_LIBRARY_PATH or LIBPATH
|
|
Packit |
85c618 |
environment variable (or the equivalent runtime library path environment
|
|
Packit |
85c618 |
variable for your system). The ICU libraries may not link or load properly
|
|
Packit |
85c618 |
without doing this.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Note that if you do not want to have to set this variable, you may instead
|
|
Packit |
85c618 |
use the --enable-rpath option at configuration time. This option will
|
|
Packit |
85c618 |
instruct the linker to always look for the libraries where they are
|
|
Packit |
85c618 |
installed. You will need to use the appropriate linker options when linking
|
|
Packit |
85c618 |
your own applications and libraries against ICU, too. Please refer to your
|
|
Packit |
85c618 |
system's linker manual for information about runtime paths. The use of rpath
|
|
Packit |
85c618 |
also means that when building a new version of ICU you should not have an
|
|
Packit |
85c618 |
older version installed in the same place as the new version's installation
|
|
Packit |
85c618 |
directory, as the older libraries will used during the build, instead of the
|
|
Packit |
85c618 |
new ones, likely leading to an incorrectly build ICU. This is the proper
|
|
Packit |
85c618 |
behavior of rpath.

|
|

|
|
Packit |
85c618 |
If you are using ICU's Makefiles to build ICU on a new platform, there are
|
|
Packit |
85c618 |
a few places where you will need to add or modify some files. If you need
|
|
Packit |
85c618 |
more help, you can always ask the
|
|
Packit |
85c618 |
"http://site.icu-project.org/contacts">icu-support mailing list. Once
|
|
Packit |
85c618 |
you have finished porting ICU to a new platform, it is recommended that you
|
|
Packit |
85c618 |
contribute your changes back to ICU via the icu-support mailing list. This
|
|
Packit |
85c618 |
will make it easier for everyone to benefit from your work.

Data For a New Platform
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
For some people, it may not be necessary for completely build ICU. Most of
|
|
Packit |
85c618 |
the makefiles and build targets are for tools that are used for building
|
|
Packit |
85c618 |
ICU's data, and an application's data (when an application uses ICU resource
|
|
Packit |
85c618 |
bundles for its data).
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Data files can be built on a different platform when both platforms share
|
|
Packit |
85c618 |
the same endianness and the same charset family. This assertion does not
|
|
Packit |
85c618 |
include platform dependent DLLs/shared/static libraries. For details see the
|
|
Packit |
85c618 |
User Guide ICU
|
|
Packit |
85c618 |
Data chapter.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
ICU 3.6 removes the requirement that ICU be completely built in the native
|
|
Packit |
85c618 |
operating environment. It adds the icupkg tool which can be run on any
|
|
Packit |
85c618 |
platform to turn binary ICU data files from any one of the three formats into
|
|
Packit |
85c618 |
any one of the other data formats. This allows a application to use ICU data
|
|
Packit |
85c618 |
built anywhere to be used for any other target platform.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
WARNING! Building ICU without running the tests is not
|
|
Packit |
85c618 |
recommended. The tests verify that ICU is safe to use. It is recommended that
|
|
Packit |
85c618 |
you try to completely port and test ICU before using the libraries for your
|
|
Packit |
85c618 |
own application.

|
|
Packit |
85c618 |
Try to follow the build steps from the UNIX
|
|
Packit |
85c618 |
build instructions. If the configure script fails, then you will need to
|
|
Packit |
85c618 |
modify some files. Here are the usual steps for porting to a new
|
|
Packit |
85c618 |
platform:
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Create an mh file in icu/source/config/. You can use mh-linux or a
|
|
Packit |
85c618 |
similar mh file as your base configuration.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Modify icu/source/aclocal.m4 to recognize your platform's mh file.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Modify icu/source/configure.in to properly set your platform C
|
|
Packit |
85c618 |
Macro define.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Run autoconf in
|
|
Packit |
85c618 |
icu/source/ without any options. The autoconf tool is standard on most
|
|
Packit |
85c618 |
Linux systems.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
If you have any optimization options that you want to normally use, you
|
|
Packit |
85c618 |
can modify icu/source/runConfigureICU to specify those options for your
|
|
Packit |
85c618 |
platform.
|
|
Packit |
85c618 |
|
|
Packit |
85c618 |
Build and test ICU on your platform. It is very important that you run
|
|
Packit |
85c618 |
the tests. If you don't run the tests, there is no guarentee that you have
|
|
Packit |
85c618 |
properly ported ICU.
