#include 

void* cuoco(void* arg)
{
    fprintf(stderr,\"Inizio codice cuoco\\n\");
    fprintf(s         


        

Answer 1

Without seeing the compiler command, I suspect -lpthread is not at end. Libraries need to be placed at end of the compiler command:

gcc main.c -lpthread

However, use -pthread instead of -lpthread, as -pthread may add other settings (like defining the macro _REENTRANT for example).
