New map in veins example does not start automatically with QTenv launch, how to do that?

I created a map with osmWebWizard.py and that's working well in Sumo. When importing it in veins example and hit "Play/Start" on the simulation nothing happens until I also hit the Start button in Sumo-gui as well. If I never hit it in Sumo, QTenv is going to "Not respond" or crash. Why is this happening? Can it be changed manually?

Also obstacles are not being recognized as expected, although the *.poly.xml file exists and also I've built myself with polyconvert function. That's why I also tried GatcomSUMO but on my system is not working very well, I'm on Linux, while in the video Windows is being used and the process seems pretty straight forward. After a series of warnings I'm getting an error. Here is the log:

Solution

To allow QTenv to run both Omnet++ simulation and SUMO it's important to set the <gui_only> parameters in the *.sumo.cfg file. By default osmWebWizard tool is pointing to the *.view.xml file, which is left to be modified by the user.

The solution is to add the following lines in the sumocfg file:

<gui_only>
        <start value="true"/>
</gui_only>

For those who want to give a try to GatcomSUMO, you have this parameter in the OMNeT++ tab, check the following screen:

Here is a video showing how to use GatcomSUMO in Linux. It's important to copy .jar and src sumo folder in the same directory, this is what I was missing.
