I have a simple c++ header that looks something like the following, and it errors out when running "importExternalCTypes" with "dot indexing is not supported ..."
is there a trick to importing c++ enum classes with namespaces?
namespace Outside {
namespace Inside {
enum class MyEnum {
One, Two, Three
};
}
}

Hi @Patrick,
While importing C++ enum classes using importExternalCTypes, I encountered a similar error.
One workaround I tried was converting the '.hpp' files to C-style '.h' files. After this, I used the Simulink.importExternalCTypes command.
Alternatively, you can try upgrading to MATLAB R2025a, as this issue is completely resolved, even when using '.hpp' files.
I hope this helps!
