Why is the build process failing in Simulink?

I'm trying to build a built-in demo, I get an error message stating that the build has failed.

The error message is the following:

gmake: *** [IdenImpe.obj] Error 1

gmake: *** Waiting for unfinished jobs....

C:\Users\Fio\Desktop\IdenImpe_ert_rtw>echo The make command returned an error of 2 T

he make command returned an error of 2 C:\Users\Fio\Desktop\IdenImpe_ert_rtw>exit 1

Hi Da Wang,

The error you are facing is likely to be caused due to version compatibility issue between MATLAB and MinGW. You can use the following support package to install the correct version of MinGW based on your MATLAB version - https://www.mathworks.com/matlabcentral/fileexchange/52848-matlab-support-for-mingw-w64-c-c-fortran-compiler?s_tid=srchtitle

You can also check the Supported MATLAB version for a MinGW version from the above page.
