Veins & Sumo - Error while running my own scenario

[Georgios]

Dear all,

I would like to solve a problem in Veins-Omnetpp-Sumo.

I have created my own scenario in veins but when I run the scenario I have the following error in SUMO:

Loading configuration... done. ***Starting server on port 34236 *** Loading net-file from 'map.net.xml'... done (528ms). Loading done. Warning: Environment variable SUMO_HOME is not set, schema resolution will use slow website lookups. Error: An exception occurred! Type:NetAccessorException, Message:Could not open file: http://sumo-sim.org/xsd/routes_file.xsd In file 'map.rou.xml' At line/column 1/0. Quitting (on error).

In the past, I used another version of veins and my scenarios worked correctly.

Thanks for your time and I m waiting for your help.

Regards,

Georgios

Unfortunately, recent versions of SUMO have started to try and validate
XML files when loading them (which often fails for various reasons).

You can turn off schema validation in the SUMO configuration file by adding

<report>
<xml-validation value="never"/>
</report>

to the top level <configuration> tree.


Best,

Christoph
