newbie Q: how to use stl hash_set in gcc3.4.4

[zl2k]

hi, there

Can someone let me know how may I use the stl hash_set in gcc3.4.4?
Here is my code:
======================
#include <ext/hash_set>

using namespace std;

int main (void)
{
hash_set<int> hs; //error message "`hash_set' undeclared (first use
this function)"
return 0;
}
======================
Thanks ahead.

Probably your system (rightly) puts hash_table in a namespace other than
std. You can look in your system's include directories to see how it's
defined. I'm using an older version of gcc and it looks like it's
within namespace __gnu_cxx

Thanks Mark, you are right. By using the namespace __gnu_cxx, it works.
