What is causing this template-related compile error? (c++)
- by Setien
When I try to compile this:
#include <map>
#include <string>
template <class T>
class ZUniquePool
{
typedef std::map< int, T* > ZObjectMap;
ZObjectMap m_objects;
public:
T * Get( int id )
{
ZObjectMap::const_iterator it = m_objects.find( id );
if( it == m_objects.end() )
{
T * p = new T;
m_objects[ id ] = p;
return p;
}
return m_objects[ id ];
}
};
int main( int argc, char * args )
{
ZUniquePool< std::string > pool;
return 0;
}
I get this:
main.cpp: In member function ‘T* ZUniquePool<T>::Get(int)’:
main.cpp:12: error: expected `;' before ‘it’
main.cpp:13: error: ‘it’ was not declared in this scope
I'm using GCC 4.2.1 on Mac OS X.
It works in VS2008.
I'm wondering whether it might be a variation of this problem:

But as my error output is only partially similar, and my code works in VS2008, I am not sure.
Can anyone shed some light on what I am doing wrong?
