I checked the internet and the same error warning happened when there is a mismatch of the number of opened/closed {} but I cannot see this here. What can be the error?

Where? I putted the code of the header at the end. As can be seen, I only open one { , the class one, that I also close.

Edit: Figured out the error, was not paying attention to the header files included in the "RayTracer.h" header. In one of them there was the single opened {

it might be in GeometricObjects.h or Image.h

Do you have a semi-colon ; at the end of RayTracer.h?
