Je n'y connais rien, mais absolument rien mais:
[anne@localhost]# cat helloworld.c
#include <iostream>
int main () {
std::cout<<"Hello World!\n";
}
[anne@localhost]# gcc helloworld.c
helloworld.c:1:20: iostream: No such file or directory
[anne@localhost]# g++ helloworld.c
[anne@localhost]# g++ -o helloworld helloworld.c
[anne@localhost]# ./helloworld
Hello World!
# rpm -qf /usr/bin/g++

Plus de détails qui m'ont donné des pistes:
