It seems very strange to me, but in the following code, gcc complains that it
doesn't find 'propagate' with a correct signature though it exist in the base
class as a template method. If I change the name 'propagate' into 'prop', then
it compiles happily.
Sebastien.
template< typename T, typename X >
class propJoin : public joinOp<T> {
public:
template< typename Iter >
void propagate( const T& n, Iter first, Iter last ) {
std::cout << "propJoin<T,X>::propagate( const T& node, Iter first, Iter
last )" << std::endl;
}
};
class node {
};
class info {
};
class dfgBackProp : public propJoin<node,info> {
public:
void propagate( const node& n ) {
std::vector<info> infos;
propagate(n,infos.begin(),infos.end());
}
};
