The following sample fails to compile:
template<class _Type, int _Val>
class Container
{
static const _Type Value = _Val;
};
template<class _Type>
class Test
{
static const uint Value = 2;
static const Container<_Type, Value> m_Test;
};
template<class _Type>
const Container<_Type, Test<_Type>::Value> Test<_Type>::m_Test;
The compiler says:
Test.cpp:29: error: conflicting declaration 'const Container<_Type,
Test<_Type>::Value> Test<_Type>::m_Test'
Test.cpp:24: error: 'Test<_Type>::m_Test' has a previous declaration as 'const
Container<_Type, 2> Test<_Type>::m_Test'
Test.cpp:29: error: declaration of 'const Container<_Type, 2>
Test<_Type>::m_Test' outside of class is not definition
The problem is the Test<_Type>::Value in the definition - if i replace it with
2 it is working. I tried the sample above with Visual Studio 2005 and Comeau
4.3.3 (Online) and both compile without any error.
