Beyond Linux® From Scratch (systemd Edition) - Version 10.1

Chapter 9. General Libraries

ICU-68.2

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-10.1 platform.

Package Information

ICU Dependencies

Optional

LLVM-11.1.0 (with Clang), and Doxygen-1.9.1 (for documentation)

Installation of ICU

[Note]

Note

If clang++ is available, it will be used in the mistaken belief that g++ might not support C++11, even though configure has tested for that. If using g++ there will be an unnecessary warning at the end of configure. Building with g++ also takes longer than the estimated SBU shown.

Install ICU by running the following commands: 

cd source                                    &&

./configure --prefix=/usr                    &&
make

To test the results, issue: make check.

Now, as the root user: 

make install
