I'm compiling the Rose compiler infrastructure toolkit using Clang,
something that afaik no one has done lately. There haven't been too
many issues, but I have one that I don't know how to fix, or whether to
bring to the Clang folks. Or maybe I need a newer Clang....
It's an out-of-line template class function definition. Both
declaration and definition are in the same .h file.
Here's the declaration:
template<
template class ValueType>
class State = PartialSymbolicSemantics::State,
template
class ValueType = PartialSymbolicSemantics::ValueType
>
class Policy: public BaseSemantics::Policy {
/* ... */
void print_diff(std::ostream&,
const State&,
const State&,
RenameMap *rmap=NULL) const ;
/* ... */
};
and the definition:
template<
template class ValueType> class State,
template class ValueType
>
void
Policy::
print_diff(std::ostream &o,
const State &s1,
const State &s2,
RenameMap *rmap/*=NULL*/) const
{ /* ... */ }
and the error message:
[...]/instructionSemantics/PartialSymbolicSemantics.h:1062:39:[...]:
error: out-of-line definition of 'print_diff' does not match
any declaration in 'Policy' [2]
Policy::print_diff(std::ostream &o,
~~~~~~~~~~~~~~~~~~~~~~~~~~^
What say you? The code looks OK to me, and GCC compiles it. But it
wouldn't be the first time I failed to detect a missing "typename"
keyword.
