Header file error in simulink

An error occurs when I try to build and deploy my simulink code to a lego mindstorm robot

My error says:

Error(s) encountered while building "filename"

Caused by:

• The compiler error indicates that a type is redefined. Tjis error can occur if your costum code includes the header file tmwtypes.h instead of rtwtypes.h. For information about using the directive #include "tmwtypes.h" in costume code, refer to the documentation. Alternatively, specify backwards compatibility for your model by running set_param('filename', 'InterredTypesCompatibility', 'on'.

Component: Simulink | Category: Block diagram error

It seemes that something goes wrong when saving the file, but I'm not sure. I also tried to update MATLAB, because I thought the missing update might help if it's a bug, but I got an error message threre aswell (which referd me to the ask community site).

I'd appreciate any help:)

did you run ?

set_param('filename', 'InterredTypesCompatibility', 'on')

In above case filename is not variable what is your filename?
