Warning

Iceberg was decommissioned on 30th November 2020. Users of Iceberg need to switch to using ShARC and/or Bessemer instead.

icu - International Components for Unicode¶

ICU is a mature, widely used set of C/C++ and Java libraries providing Unicode and Globalization support for software applications. ICU is widely portable and gives applications the same results on all platforms and between C/C++ and Java software.

ICU is released under a nonrestrictive open source license that is suitable for use with both commercial software and with other open source or free software.

Usage¶

Version 58.1 of the icu library for C requires gcc version 4.9.2 (for the C++ standard library); To make the library and this compiler available, run the following:

module load libs/gcc/4.9.2/icu/58.1

Version 55 of the icu library for C requires gcc version 4.8.2. To make the compiler and library available, run the following module commands:

module load compilers/gcc/4.8.2
module load libs/gcc/4.8.2/icu/55

Version 42 of the icu library for C uses gcc version 4.4.7 which is the default on Iceberg. To make the library available, run the following command:

module load libs/gcc/4.4.7/icu/42

Installation Notes¶

This section is primarily for administrators of the system.

Version 58.1¶

This Icu 58.1 build links against the GCC 4.9.2 C++ standard library and was installed as a dependency of boost_iceberg (build using the same C++ standard library); Boost in turn was installed as a dependency of Gromacs 2016.1.

module load compilers/gcc/4.9.2
tar -xvzf icu4c-58_1-src.tgz
cd icu/source
./runConfigureICU Linux/gcc --prefix=/usr/local/packages6/libs/gcc/4.9.2/icu/58.1/
make
make check
make install

Version 55¶

Icu 55 is a pre-requisite for the version of boost_iceberg required for an experimental R module used by one of our users. It was built using gcc 4.8.2.

module load compilers/gcc/4.8.2
tar -xvzf icu4c-55_1-src.tgz
cd icu/source
./runConfigureICU Linux/gcc --prefix=/usr/local/packages6/libs/gcc/4.8.2/icu/55/
make
make check
make install

Version 42¶

Icu version 42 was originally installed as a system RPM. This install moved icu to a module-based install.

tar -xvzf icu4c-4_2_1-src.tgz
cd icu/source/
./runConfigureICU Linux/gcc --prefix=/usr/local/packages6/libs/gcc/4.4.7/icu/42
make
make check
make install

Testing¶

Version 58.1¶

Last few lines of output from make check were:

ALL TESTS SUMMARY:
All tests OK:  testdata intltest iotest cintltst
make[1]: Leaving directory `/home/te1st/icu_gcc_4_9_2/icu/source/test'
make[1]: Entering directory `/home/te1st/icu_gcc_4_9_2/icu/source'
verifying that icu-config --selfcheck can operate
verifying that make -f Makefile.inc selfcheck can operate
PASS: config selfcheck OK

Version 55¶

Last few lines of output from make check were:

[All tests passed successfully...]

Version 42¶

Last few lines of output from make check were:

All tests passed successfully...]
Elapsed Time: 00:00:12.000
make[2]: Leaving directory `/home/te1st/icu/source/test/cintltst'
---------------
ALL TESTS SUMMARY:

===== ERRS:  intltest
make[1]: *** [check-recursive] Error 1
make[1]: Leaving directory `/home/te1st/icu/source/test'
make: *** [check-recursive] Error 2

The error can be ignored since it is a bug in the test itself.
