Beyond Linux® From Scratch (System V Edition) - Version r12.2-1434

Chapter 9. General Libraries

Apr-1.7.5

Introduction to Apr

The Apache Portable Runtime (APR) is a supporting library for the Apache web server. It provides a set of application programming interfaces (APIs) that map to the underlying Operating System (OS). Where the OS doesn't support a particular function, APR will provide an emulation. Thus programmers can use the APR to make a program portable across different platforms.

This package is known to build and work properly using an LFS 12.3 platform.
