Coding error on BaseMacLayer

Question

When building the Veins (Version:4.4) on Omnet version omnetpp-5.1pre2-src-windows, I get the following error output:

**19:58:05 **** Incremental Build of configuration gcc-release for project veins ****
make MODE=release all

Appreciate if someone can help me on this.

Answer 1

Though, admittedly, this also points to an underlying inconsistency in the code, Veins 4.4 is a simulation module library for OMNeT++ 4.6. It is also compatible with OMNeT++ 5.0.

You are using a version of OMNeT++ (5.1 pre-release) that Veins is not compatible with.

This means that a downgrade of your OMNeT++ installation should rectify the build error.

The Veins tutorial on http://veins.car2x.org/tutorial/ goes into more detail of which software needs to be installed (and how) for Veins to work.
