Coder typedefs compatibility

Option to force generation of rtwtypes.h file

Since R2023a

Model Configuration Pane: Code Generation / Data Type Replacement

Description

If you set Data type replacement to Use C data types with fixed-width integers, the generated code uses data types from the C99 language standard and does not require rtwtypes.h definitions. By default, the code generator does not create the rtwtypes.h file. The rtwtypes.h file is generated in some cases because it might be needed by static source code located under matlabroot. If you use custom code that requires Simulink® Coder™ data type definitions, select the Coder typedefs compatibility check box to force the generation of the rtwtypes.h file.

Dependencies

To enable this parameter, set Data type replacement to Use C data types with fixed-width integers.
