I get some compiling errors about template instantiation , but I can't find where the syntax errors happens. Can some help me?
Code:
template<typename Type> class SingleList;
template<typename Type> class SingleListNode{
private:
friend class SingleList<Type>;
SingleListNode() : next(NULL){}
public:
friend ostream& operator<< <Type>(ostream& os,SingleListNode<Type>& sln); //Error!!!
private:
SingleListNode *next;
};
template<typename Type> ostream& operator<<(ostream& os,SingleListNode<Type>& out){
os<<out.data;
return os;
}
template<typename Type> class SingleList{
public:
SingleList()
{
head = new SingleListNode<Type> () ; //Error!!!
}
~SingleList(){
delete head;
}
private:
SingleListNode<Type> *head;
};
Compiler error message:

mkdtemp
MKDTEMP(3) Linux Programmer's Manual MKDTEMP(3)NAME
mkdtemp - create a unique temporary directory
SYNOPSIS
#include <stdlib.h>
char *mkdtemp(char *template);
DESCRIPTION
The mkdtemp() function generates a uniquely-named temporary directory from template. The last six characters of template must be XXXXXX and
these are replaced with a string that makes the directory name unique. The directory is then created with permissions 0700. Since it will
be modified, template must not be a string constant, but should be declared as a character array.
RETURN VALUE
The mkdtemp() function returns a pointer to the modified template string on success, and NULL on failure, in which case errno is set appro-
priately.
ERRORS
EINVAL The last six characters of template were not XXXXXX. Now template is unchanged.
Also see mkdir(2) for other possible values for errno.
CONFORMING TO
Introduced in OpenBSD 2.2. Available since glibc 2.1.91.
