Hi,
The code below compiles fine with Intel's icc. However,
all gcc versions refused to compile it saying :
g++ -c -o ttt.o ttt.cpp
ttt.cpp: In instantiation of `Property<F>':
ttt.cpp:15: instantiated from `bool Property<T>::change(PropOp*) [with T =
double]'
ttt.cpp:23: instantiated from here
ttt.cpp:13: error: `Property<T>::val' has incomplete type
ttt.cpp:1: error: forward declaration of `struct F'
-----Code-----
struct F;
template< class T >
struct Property;
struct PropOp {
bool update( Property<F>* f) { return false; }
bool update( Property<double>* d) { return true; }
};
template<class T>
struct Property {
T val;
bool change( PropOp* p) {
return p->update( this ); // Line 15
}
};
int main()
{
PropOp po;
Property<double> pd; // Line 23
pd.change( &po );
return 0;
}
----EndCode---
May I submit this as a bug ? I believe Property<F> should not be instantiated
in line 15, only Property<double> should be.
Peter
