We have an error building a Kokkos-based app for AMD MI300A GPUs. We've reduced the code to a few lines while still getting the same error message. The following code produces an error when using the AMD gfx942 target.
`#include <string>
class LabeledObject
{ std::string label; public: LabeledObject(); virtual ~LabeledObject(); }
;
class Describable : virtual public LabeledObject
{ public: virtual ~Describable(); virtual std::string describe() = 0; }
;
template <class Scalar>
class ScalarProdBase : virtual public Describable
{
public:
std::string describe()
{ return "foo"; }
protected:
virtual bool bar() = 0;
};
template class ScalarProdBase<double>;`
I'm using the following command to build:
`clang++ --std=c++20 -xhip -o repro.o -c repro.cpp --offload-arch=gfx942`
Notably, the error does not happen when using --std=c++17, but the code need c++20 for other parts.
This is the error output I see:
