Atualmente estou escrevendo um aplicativo C ++ que implementa um Oscilador em conjunto com math.h. O código que tenho deve funcionar bem para o aplicativo (tentando compilar um arquivo de objeto), mas estou recebendo um erro do compilador muito provavelmente ter a ver com a sintaxe / etc; Eu acho que tem algo a ver com o namespace. O erro:

Saída Terminal:

Já vi outras sugestões que mencionam o uso do g ++ -Wall -g, mas não tenho certeza se esse é o problema, e que há algo mais acontecendo aqui.

Qualquer ajuda seria muito apreciada! Obrigado!!
