¿Este mensaje es un error o una advertencia? ¿Qué puedo hacer para solucionarlo?
Respuesta1
No es un error ni una advertencia: es elverbososalida, incluida la ruta de búsqueda del preprocesador. 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.
Si desea solo la información de la versión, puede usar cpp --version
:
-version
--version
Print out GNU CPP's version number. With one dash, proceed to
preprocess as normal. With two dashes, exit immediately.
