Beyond Linux® From Scratch (systemd Edition) - Version r11.0-57

Chapter 9. General Libraries

Apr-1.7.0

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-11.0 platform.

Installation of Apr

First, fix a security issue: 

sed -e "/shift/i \
\    if (xt->tm_mon < 0 || xt->tm_mon >= 12) return APR_EBADDATE;" \
    -i time/unix/time.c

Install Apr by running the following commands: 

./configure --prefix=/usr    \
            --disable-static \
            --with-installbuilddir=/usr/share/apr-1/build &&
make

To test the results, issue: make test.

Now, as the root user: 

make install
