template-id `hash_set<Tool*>' used as a declarator

[Vasileios]

Hello could someone help me please.


I have the following class definition

#include <ext/hash_set>
#include "tool.h"

class ToolContainer : public QObject
{

public:

typedef std::hash_set<T ool*> ToolSet;
....
....
....


and when I compile I get the following:


toolcontainer.h :9: template-id `hash_set<Tool* >' used as a declarator
toolcontainer.h :9: parse error before `;' token



Any ideas why and how I could correct this error?

I am using GCC 3.27

There is no standard template 'hash_set', so are you sure that it's in
namespace std? It wouldn't be allowed to.

There is no version 3.27 of gcc. See http://gcc.gnu.org/releases.html
for a list of all gcc releases.

ok
I tried with
typedef hash_set<Tool*> ToolSet;

but I get exactly the same error.

Ok, I had a look into gcc's has_set header (which you could have done
easily too), and found out that hash_list is in namespace __gnu_cxx.

Sorry, of course I meant hash_set.
