9.1 General
9.1.1 What are the differences between Webots FREE, Webots EDU and Webots PRO?
Webots FREE is a limited version which suits to our online programming contests: Robotstadium and Rat's Life. Webots EDU and Webots PRO are commercial versions of Webots, their differences are explained here.
9.1.2 How can I report a bug in Webots?
If you can still start Webots, please report the bug by using Webots menu: Help > Bug report....
If Webots cannot start any more, please report the bug there: http://www.cyberbotics.com/bug. Please include a precise description of the problem, the sequence of actions necessary to reproduce the problem. Do also attach the world file and the controller programs necessary to reproduce it.
Before reporting a bug, please make sure that the problem is actually caused by Webots and not by your controller program. For example, a crash of the controller process usually indicates a bug in the controller code, not in Webots. This situation can be identified with these two symptoms:
-
Webots GUI is visible and responsive, but the simulation is blocked (simulation time stopped).
-
The controller process has vanished from the Task Manager (Windows) or is shows as <defunct> when using ps -e (Linux/Mac).
9.1.3 Is it possible to use Visual C++ to compile my controllers?
Yes. However, you will need to create your own project with all the necessary options. You will find more detailed instructions on how to do that in section 5.6. To create the import libraries (the *.lib files in Visual C++) from the *.dll files of the lib directory of Webots, please follow the instructions provided with the documentation of your compiler.
