Hi,

I am aware of the option to suppress all output using Python using the following

https://support.gurobi.com/hc/en-us/articles/360044784552-How-do-I-suppress-all-console-output-from-Gurobi-

However, I cannot find a similar way when using the C++ API. Is there a solution available?

Thanks

Pirmin

Hi Pirmin,

Similar to Python API, to suppress all console output from Gurobi with C++ API, we can set the OutputFlag to 0 before the Gurobi environment is started.
```
//create an empty environment
GRBEnv env = GRBEnv(true);

env.set(GRB_IntParam_OutputFlag, 0);
env.start();
```
Best regards,
Simran
