Simulink Coder Error: Error occurred when generating rtwtypes.h

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 maybe that you need to update/replace some of the old blocks for the new version of Matlab/Simulink. There's a "Upgrade Advisor" tool hiddent somewhere in the menus that may help you.

Blessings,

Spencer

Check if your file genRTWTYPESDOTH.m is up-to-date by comparing with the 2021b file.

I got a same error message. Did you solve it?

[Yuki Deguchi]

It was caused by a path to an older version of genRTWTYPESDOTH.m.

Removing it from the path solved the problem.
