Creating the environment

Creating the environment

The first executable statement in our example obtains a Gurobi environment (using the GRBEnv() constructor):


      // Create an empty environment, set options and start
      GRBEnv    env   = new GRBEnv(true);
      env.Set("LogFile", "mip1.log");
      env.Start();

In this case, we create an empty environment, select a log file to use, and start the environment for latter use.

Later calls to create an optimization model will always require an active environment, so environment creation is typically the first step in a Gurobi application. The constructor argument specifies the name of the log file.
