Arch Linux¶

Supported Releases¶

This chapter provides additional information for installing OMNeT++ on Arch Linux. The overall installation procedure is described in the Linux chapter.

These instructions assume you are using the pacman package manager.

Installing the Prerequisite Packages¶

First, ensure your system’s package database is up to date and install the core development tools and libraries:

$ sudo pacman -Sy --needed --noconfirm make diffutils ccache clang pkgconf lld lldb gdb \
    bison gawk flex perl python python-pip libxml2 zlib doxygen graphviz \
    xdg-utils libdwarf

Next, install packages for the graphical environment (Qtenv and IDE). If you do not need GUI support (e.g., for a server installation), you can skip this step and later configure OMNeT++ with WITH_QTENV=no and WITH_OSG=no.

$ sudo pacman -Sy --needed --noconfirm qt6-base qt6-svg qt6-wayland webkit2gtk-4.1

For 3D visualization support in Qtenv, install the OpenSceneGraph package. If you do not need 3D support, you can skip this step and later configure OMNeT++ with WITH_OSG=no.

$ sudo pacman -Sy --needed --noconfirm openscenegraph

After installing system packages, it’s good practice to clean the package cache:

$ sudo pacman -Scc --noconfirm

Note

The commands above install Clang as the C++ compiler and LLD as the linker. If you prefer to use GCC and the system’s default linker, you can adjust the package list accordingly (e.g., replace clang with gcc and omit lld) and set the PREFER_CLANG=no and PREFER_LLD=no options in the configure.user file or during the ./configure step. If you skip the GUI or 3D packages, remember to disable the corresponding features (WITH_QTENV=no, WITH_OSG=no) in configure.user or during the ./configure step.

To enable the optional parallel simulation support you will need to install an MPI package (e.g., OpenMPI):

$ sudo pacman -Sy --needed --noconfirm openmpi

Refer to the Arch Linux documentation for managing MPI environments if needed.
