Header file is not compiling

Hello,

in my data dictionary I defined an enumeration with Data Scope "Imported" and a header file. In the header file there are a bunch of enumerations/structs defined, not only the one used in Simulink (because it's importet from other source code). The header file is stated in the configuration in "Simulation Target" -> "Custom Code". When I want to compile I get an error, because in the header file there are enumerations/structs which Simulink does not know. But I want Simulink to search only for the enumerations I have specified in my data dictionary and not care about other stuff in the header file. Is there a way how to handle that?

Thank you

This is more of a limitation of normal C coding - if a header file is included, all of the contents of the header file must be defined.

There are a few workarounds:

1. Create a separate header file (data_dictionary_enums.h for example) with only the enumerations needed by the Data Dictionary, and then add #include "data_dictionary_enums.h" to the main header file.
2. Add a preprocessor macro to the header file such that the rest of the header file is only included when a specific define is set.
3. Add the other necessary #includes to the header file such that all the structs are fully defined.
