用了c++的模板，调用buildHuff（）时出错，我是c++新手

template
HuffTree*
buildHuff(HuffTree** TreeArray, int count)
{
//用给定的数组建堆
**_ heap> *forest = new heap>(TreeArray, count, count);
**_
HuffTree* temp1, *temp2, *temp3 = NULL;

//利用堆建树
while (forest->size() > 1)
{
    temp1 = forest->removefirst();
    temp2 = forest->removefirst();
    temp3 = new HuffTree<Element>(temp1, temp2);

    forest->insert(temp3);  //put new tree back on list

    delete temp1;
    delete temp2;
}
return temp3;

}
