Why I can't generate c++ code only using simulink coder?

When I try to generate code using simulink coder I see the following error:
The specified code generation target is configured to generate C++, but the C-only compiler, LCC, is the default compiler. To allow code generation, you can select any C++ compiler from the Toolchain pulldown as well as selecting the 'Generate code only' option. To generate C code, open the Configuration Parameters dialog and set the target language to C. Or, to specify a C++ compiler, enter 'mex -setup' at the command prompt. For details on supported C++ compiler versions, see
I want just generate C++ code only, do not use any compilers. I have activated this option. I think the reason of this error is "generate makefile" option, that is enabled. But it is read only and I can't deactivate it. How can I generate C++ code without using any compilers?

You cannot do that. If I recall correctly, one of the intermediate steps in code generation involves generating a program and running it.

I have also got exactly the same answer. Is there any possible solution to this problem? Thank you.

Probably because it is trying to create an executable out of the code and you can only do that using a compiler. Just add one it isnt not hard you can do so through Matlab add-ons or gcc, g++ compilers are standard free software
