OMNeT++ and INET Simulator Setup

I use the popular, modular OMNeT++ simulator for network simulation. The INET Framework adds lots of useful wired, wireless and mobile communication protocols and entities to the simulator.
It turns out many people have problems compiling the two. So I’d like to give a quick introduction into how I got them working.

I use OMNeT++ 5.1.1 together with INET 3.5. Both have newer versions, but another framework I use - simuLTE - requires these versions.

For 3D renders, OMNeT++ uses osgEarth, where osg stands for openscenegraph, a library that provides some rendering functionality. At the time of writing osgEarth from the AUR won’t build due to some incompatibility with the current geos 3.6. For me downgrading to geos 3.5 leads to osgEarth compiling. osgEarth installs openscenegraph as a dependency.

When this is installed, go to the directory you extracted OMNeT++ into and execute

cd <omnet-dir>/
./configure // watch out for missing packages and install as needed
make -j4

Now run a sample simulation from <omnet-dir>/samples/dyna (or any other) and make sure the simulation runs.
Next, install INET by extracting it into <omnet-dir>/inet. I believe it is important for some projects that INET resides in a directory called exactly inet (no versioning in the name). Now

cd <omnet-dir>/samples/inet
make makefiles
make MODE=release -j4

And that should be it. The biggest problems arised for me from having all dependency libraries working, which sometimes don’t play nice together when the versions are most recent. This is of course a problem of Arch Linux, which keeps verions most recent. Other distributions might work more easily.
