Quando eu verifiquei a versão cpp , ela me mostrou esta mensagem:

Esta mensagem é um erro ou um aviso ?, O que posso fazer para corrigir isso?

    

Answer 1

Não é um erro nem um aviso - é a saída detalhada , incluindo o caminho de pesquisa do pré-processador. De man cpp :

   -v  Verbose mode.  Print out GNU CPP's version number at the beginning
       of execution, and report the final form of the include path.

Se você quiser apenas as informações da versão, use cpp --version :

   -version
   --version
       Print out GNU CPP's version number.  With one dash, proceed to
       preprocess as normal.  With two dashes, exit immediately.
