Beyond Linux® From Scratch - Version 7.5

Chapter 9. General Libraries

ICU-52.1

Introduction to ICU

The International Components for Unicode (ICU) package is a mature, widely used set of C/C++ libraries providing Unicode and Globalization support for software applications. ICU is widely portable and gives applications the same results on all platforms.

This package is known to build and work properly using an LFS-7.5 platform.

Package Information

ICU Dependencies

Optional

LLVM-3.4 (with Clang)

User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/icu

Installation of ICU

Install ICU by running the following commands: 

cd source &&
CXX=g++ ./configure --prefix=/usr &&
make

To test the results, issue: make check.

Now, as the root user: 

make install

Command Explanations

CXX=g++: This environment variable forces use of g++ compiler since building with clang++ is currently broken.
