It won't compile even that simple program you suggested @trev. I tried compiling it in Lazarus and I received the same error message about the LCL.
By the way, when you suggest using a terminal, are you talking about the terminal that I can find in my Utilities folder in applications or the Lazarus terminal?
If not could you please explain further?
I apologize for my ignorance, I am not the most tech-savvy individual.
By the way, on my configure window, when opening Lazarus, I did not configure the fppkg file and just left it as is. I did not notice anything in the installation wiki that talked about what to do with it. Could this be causing the issue?
