hash_map problem

[Tabakovic Arnes]

Hi everybody!!! Ok I solved the problem!! I hope so..... What I did was to
define my own hash function before including the header
"backward/hash_map.h", NOT AFTER! And it worked! Yes the compilation shows
no more errors :)
I hope this can help anybody needing an answer to my problem :)



I WROTE:

Hi,
I have a problem using the hash_map class. Basically I can use it as a
inherited class, I can use its constructor and initialize it. Nevertheless
when I try using the "find" function or "insert" function (even maybe other
ones...) I get an compilation error that is given below. I have made my self
hash function containing the operator() : 
class hashInstanz
{
	public:
		unsigned int operator() (const instanz_t& key) const;
};
Can anybody please help me to deal with that? I will be graceful with any
help :)
