Dear all,
I have 1 model which created by MATLAB 2015a. It ran and generated code succesful.
Now I want to build by MATLAB 2019b, error occurred as following:
Error: Simulink Coder Error: Error occurred when generating rtwtypes.h: The structure argument 'configInfo' contains invalid fields, expected fieldnames are: GenDirectory PurelyIntegerCode SupportComplex MaxMultiwordBits ModelName
I don't know why. How to fix it??

It was caused by a path to an older version of genRTWTYPESDOTH.m.
Removing it from the path solved the problem.

Hi galaxy,
I understand that you are facing Simulink Coder error when generating rtwtypes.h.
This error is thrown by "genRTWTYPESDOTH," which is sometimes used to customize the "rtwtypes.h" file. Check if MATLAB is finding "genRTWTYPESDOTH" in the default location by executing
>> which genRTWTYPESDOTH
at the MATLAB prompt. The default location is $MATLAB/toolbox/rtw/rtw/genRTWTYPESDOTH.p, where $MATLAB is the directory in which MATLAB is installed.
If the "genRTWTYPESDOTH" is found in a non-default location in that case, you have two options for how to proceed:
  • If the customized version of "genRTWTYPESDOTH" is not needed, remove it from the MATLAB path by renaming or deleting it. This helps resolve the error.
  • If the customized version is needed, you can debug it by comparing it to the default version of the file. You can find the non-obfuscated version of the default file at $MATLAB/toolbox/rtw/rtw/genRTWTYPESDOTH.m.
Hope this helps!
