Why does HDL codegeneration fails for my model with a "File format not recognized" error message?

When I try to generate HDL code for my model, then it fails in one of the intermediate steps with this error message:

MEX completed successfully. ### Linking ...

This issue is caused by using an unsupported version of the MinGW compiler. In Release 2015b MATLAB on Windows only supports MinGW 4.9.2. You can use the "--version" flag on the GCC executable to find our what exact version you have.

See the following page for details on how to install the supported version of MinGW:
