External C++ library support for Simulink Realtime

I am trying to use an external C++ library on a Simulink Realtime Target (Please note : I don't mean Simulink Desktop Realtime or Simulink Realtime Windows target), a NUC PC through S-Function support. I managed to generate an S-function for the C++ library, thereby everything works normal in Simulink Normal Mode. Now when I try to generate code for Simulink Realtime the error states that the code is compiled for C++.
Simulink Coder Fatal : This S-Function generated by the Legacy Code Tool must be only used with the C++ Target Language.
How can I make this S-function compatible for SLRT code generation?

The error is because the C++ standard template library is not compatible with real-time code.

Thanks, for the answer, however I was able to get rid of this error and compile the code for RT target PC by writing a C-style wrapper for the C++ library I am using.
