Problem in executing a basic veins example

[Ivo Calado]

Hi fellows,

   I'm trying to execute the basic "hello world" example of Veins Framework. I followed all the instructions to build veins (http://veins.car2x.org/tutorial/). Nevertheless, it fails in the initialization step due to a cast problem, as shown below. Any tip on how to proceed?

Hi fellows,
I have made a workaround in order to properly execute the
aforementioned example. I just changed the headerLenght and bitrate
from double to int as the the patch presented below. Could someone
confirm if this is the correct approach to follow?

Kind regards,
Ivo

Dear Ivo,

you seem to be right
see
https://github.com/sommer/veins/commit/493f8a3f514bd8ffd7fb5d9666a952a4446ab177

you could just clone the git repo, might be easier.
