In this Step by Step tutorial we will cover different methods to install apr and apr-util package on multiple Linux distributions such as Red Hat, CentOS, Debian, Ubuntu etc. We will cover the following 2 methods of installation:
- Installation of apr and apr-util via official repository
- Download the required binary and compile them for installation
What is APR and Apr-Util?
Apache Portable Runtime (APR) is a software library that provides a supportive, predictable and consistent interface for Apache web servers. Apr-util is a companion library to APR. Their license is Apache License Version 2.0
APR provides a set of application programming interfaces (APIs) to the Operating System (OS). Software developers can use APR to make an application portable between different platforms.
Method-1: Install apr and apr-util using official repository
The installation steps will be explained as Installing from the Package Repository and Installing the Package by Compiling(From Github).
The installation of the apr libraries will be explained in 2 different operating systems.
Installation on Debian Based OS
On Debian-based(Ubuntu, Pardus etc.) systems, the name of the apr package is libapr1 and apr-util is libaprutil1. You can see the packages and its version with the following commands.
To search for the apr package
foc@foc:~$ sudo apt search "Apache Portable Runtime Library"

Full Text Search... Done
libapr1/jammy 1.7.0-8build1 amd64
Apache Portable Runtime Library
For apr-util package:
foc@foc:~$ sudo apt search "Apache Portable Runtime Utility "
Sorting... Done
Full Text Search... Done
libaprutil1/jammy 1.6.1-5ubuntu4 amd64
Apache Portable Runtime Utility Library
Then you can install the packages to the system with the following command:
foc@foc:~$ sudo apt install libapr1 libaprutil1 -y
If you want to remove the installed package, you can run the following command:
foc@foc:~/apr$ sudo apt remove libapr1 libaprutil1
Installation on Redhat Based OS
In Redhat based systems, the packages are in the repository with the same name. First, let's check the packages and their versions.
For apr package:
[foc@rocky9 ~]$ sudo dnf search apr
[sudo] password for foc:

Complete!
Installation completed successfully. If you want to remove the package from the system, you can run the following command:
[foc@rocky9 apr]$ sudo dnf remove apr apr-util
Method-2: Install apr and apr-util from github
Step-1: Download pre-requisites
We will be using Rocky Linux for this step. You must have the git and make packages on your system, run the following command in terminal to install it:
[foc@rocky9 apr]$ sudo dnf install git make -y
Step-2: Clone the apr source code from github
Then download the source codes to the local directory:
[foc@rocky9 apr]$ git clone https://github.com/apache/apr.git
Step-3: Identify and Install dependency packages
Then go to the downloaded directory:
[foc@rocky9 apr]$ cd apr/
Run the following command to find out the build dependencies:
[foc@rocky9 apr]$ sudo ./buildconf
buildconf: checking installation...
buildconf: python version 3.9.10 (ok)
buildconf: autoconf not found.
You need autoconf version 2.59 or newer installed
to build APR from SVN.
buildconf: libtool not found.
You need libtool version 1.4 or newer installed
to build APR from SVN.
The following packages are installed for the build dependencies (Python is already installed):
[foc@rocky9 apr]$ sudo dnf install autoconf libtool
Step-4: Install apr and apr-util
Then run the following commands in the terminal in order:
[foc@rocky9 apr]$ sudo autoconf [foc@rocky9 apr]$ sudo ./configure --prefix=/usr
It didn't give a warning in the buildconf command, but the error "configure: error: No XML parser found! Please specify --with-expat or --with-libxml2" requests new dependencies.
[foc@rocky9 apr]$ sudo dnf install expat expat-devel
Then the command is run again.
[foc@rocky9 apr]$ sudo ./configure --prefix=/usr
You may get the "config.status: error: cannot find input file: include/arch/unix/apr_private.h.in" error after the above command. Fix the error with the following command:
[foc@rocky9 apr]$ sudo ./buildconf
buildconf: checking installation...
buildconf: python version 3.9.10 (ok)
buildconf: autoconf version 2.69 (ok)
buildconf: libtool version 2.4.6 (ok)
buildconf: copying libtool helper files using /usr/bin/libtoolize
buildconf: creating include/arch/unix/apr_private.h.in ...
buildconf: creating configure ...
buildconf: generating 'make' outputs ...
buildconf: rebuilding rpm spec file
Generated include files already exist, the tree is not clean.
The resulting build-outputs.mk file is incorrect
Then run the following commands in order:
[foc@rocky9 apr]$ sudo ./configure --prefix=/usr [foc@rocky9 apr]$ sudo make [foc@rocky9 apr]$ sudo make install
