What are you trying to do here? If you still want a copy made, why
are you trying to hide the copy constructor?

Hi there,
I found that the compiling the following code will fail with g++ 4.1
while cmopile succeed with VC8. Any comments/suggestions is highly
appreciated.
env info
=========
g++ (GCC) 4.1.0 (SLES10)
No compile option is added
Compilation error
=================
main.cpp: In copy constructor MemAllocator<int>::MemAllocator(const
MemAllocator<int>&)
main.cpp:5: error: MemPool::MemPool(const MemPool&) is protected
main.cpp:8: error: within this context
main.cpp: In function int main()
main.cpp:32: note: synthesized method
MemAllocator<int>::MemAllocator(const MemAllocator<int>&) first
required here
Repro code
===========
class MemPool {
public:
MemPool(){};
protected:
MemPool(const MemPool& mempool);
};
template <class Type> class MemAllocator{
public:
MemPool m_pool;
MemAllocator(){}
MemPool& get_pool() const {
return m_pool;
}
template<class OtherType>
MemAllocator<Type>& operator=(const MemAllocator<OtherType>& rhs){
m_pool = rhs.get_pool;
return *this;
}
};
template <class _AllocType> class tdat_hash_map {
public:
typedef _AllocType _Alloc;
static void func(_Alloc&) {};
};
int main()
{
typedef tdat_hash_map<MemAllocator<int> > Map;
MemAllocator<int> abc = MemAllocator<int>();
return 0;
}
Thanks,
