The "[bcc32c Error] dxEMF.Utils.hpp(124): no matching function for call to '_op_Equality' / '_op_Inequality'" error occurs when compiling an application in C++Builder 10.3.3 Rio

created 5 years ago (modified 5 years ago)

We are working to find a solution to this issue. In the meantime, please follow the steps below to work around it:

  • Navigate to the erroneous line in the dxEMF.Utils.hpp.
  • Remove the const keyword before System::TObject*& __rhs so that the line looks as follows:
C/C++
bool __fastcall operator==(System::TObject*& __rhs) { return TdxSmartValue::_op_Equality(*this, __rhs); };
  • Recompile your application.

Additional information:

We found out that this RAD Studio issue (https://quality.embarcadero.com/browse/RSP-27504) causes the problem. We worked it around in our code for the TdxSmartValue record used internally.
