I’m looking for some help with running C++ code. Although “PhysicsThread” and “main” is defined once in the file I got “multiple definition error”. Also, for the “no such file or directory” error I do not have a solution as well.

Here is the written version of the error:

For “No such file or directory” part, I gave input to run the necessary function but it did not help. For the mentioned two functions, I checked whether there are more than one in the file and script. But both functions are only one time used in the file.
