eclipse :Program "g++" not found in PATH

[ylxin1993]

I've already install the gcc, g++ compiler, and jdk, but I just write a simple test, eclipse find problem, but it can run through it detect problem

#include <iostream>

using namespace std;

int main() {
	cout << endl;
	cout << endl;
	cout << "kill them all." << endl;

	return 0;
}

in the ecplise problem tab, it says :

Program "g++" not found in PATH
Symbol 'cout' could not be resolved kill.cpp /an line 12 Semantic
Symbol 'cout' could not be resolved kill.cpp /an line 14 Semantic
Symbol 'cout' could not be resolved kill.cpp /an line 13 Semantic

here's my compiler:

root@yuan:/usr/bin# ls -l gcc* g++* cpp*
lrwxrwxrwx 1 root root 7 Oct 28 14:25 cpp -> cpp-4.7

It's so weird, I reextract again the eclipse.atr.gz, so there's two eclipse folders , when I use the new eclipse, it still doesn't work out, and then i delete them all, and reextract again, OMG, it work, and there's no error, what's the matter with eclipse??
