The package named OleCalc don't compile under windows using MSVS19 or Clang both in 64 bits

Contraty to MSVS, clang have 41 compilations error when MSVS have only 1.
Can someone can confirm me OLE/ activeX control can't be compiled using clang but only with MSVS ?

Also, about MSVS : when I try to compile it the first error which is raise is this one :
template <>
inline unsigned GetHashValue(const Guid& guid) { return GetHashValue(~guid); }

Error C912: the explicit specialization 'unsigned int Upp :: GetHashValue (const Upp :: Guid &)' is not a specialization of a function template

If I try to remove the 'template <>' then the next compilation error is :
error C2259: 'Upp :: OcxObjectWrapper <Calculator>': unable to instantiate abstract class

The IViewObject Draw(...) method is abstract

I have fixed it a bit, be seriously thing rather about removing the whole OCX stuff. I do not remember using this in practice... and OCX seems to be sort of out of fashion anyway.

Moved Ole to archive. If there is anybody willing to fix it and maintain it, I would be glad to move it back. Or it can be in UppHub...

However, I have no knowledge about ActiveX. This exemple compile but linker tell me "linking has failed" but just under this it tell me
"creation of library ... OleCalc.lib and object OleCalc.exp"

I'm a bit confused. It generate dll and lib. but I thought this exemple was supposed to be a launchable TopWindow Apllicaton which I could drive using OLE ?
