Try g++ rather than gcc 

luggage:~/cpp> g++ -o test t.cpp 
luggage:~/cpp> ./test 
Hello World
luggage:~/cpp> 
luggage:~/cpp> gcc -o test t.cpp 
/tmp/ccLTlmz5.o: In function `main':
/tmp/ccLTlmz5.o(.text+0xf): undefined reference to `cout'
/tmp/ccLTlmz5.o(.text+0x14): undefined reference to `ostream::operator<<(char 
const *)'
collect2: ld returned 1 exit status
luggage:~/cpp>
