Re: [sumo-user] I am unable to start sumo from c++ by using libtraci

Dear Milad,

 

there are two things to consider:

• libtraci namespace (but as long as you have libsumo installed, the actual code for running sumo is the same)
• libtraci::Simulation::start will take the full call to sumo (path to sumo and command line arguments) - you don't separate that into two arguments but have to provide one vector of strings containing all (as in the example you adapted)

Best regards

Mirko

Good Morning

 

I hope this email finds you well. I am currently trying to start sumo from an unreal engine c++ program. importing libtraci library was successful. However , I cannot start sumo based on the sample in libtraci documentation. here is my code:

 

 

 
 std::string sumoPath = "C:\Users\simone\Downloads\sumo-1.19.0\bin\sumo-gui"; 

 std::vector<std::string> sumoArgs = { "-n", "C:\Users\simone\Downloads\sumo-1.19.0\bin\montreal1.net" };

libsumo::Simulation::start(sumoPath, sumoArgs);

 // Simulate for 5 steps
 for (int i = 0; i < 5; i++) {
    libsumo::Simulation::step();
 }

  libsumo::Simulation::close();

 

 

 

However, I think I am entering the argument wrong. What should be the argument of the start method?
start({"sumo", "-n", "net.net.xml"});

 

 

I appreciate your help and answer my question. Thank you so much.

 

Best regards,

Milad
