Simulink Coder: TYPECAST must map to a C type in the target hardware (uint64 does not map to a 64-bit C type)

Hi,

I am trying to generate code for a Simulink model (with included Matlab functions) with the Simulink coder. I get the following error message:

For code generation, integer input or result classes for TYPECAST must map directly to a C type in the target hardware. 
The class uint64 does not map to a 64-bit C type.

The error occurs in the following line:

var_msg_count_uint8 = typecast(object.msg_count, 'uint8');

where object is a bus object, and msg_count is defined as uint64. Background: To be able to send the object using dsp.sendUdp, we create a uint8 packet from it.

Code Generation Settings in Simulink Coder:

• System target file: Visual C/C++ Solution file for Simulink Coder
• Objective: Debugging
• Hardware board: None
• Device vendor: Intel
• Device type: x-86-64 (Windows64)
• Support long long enabled (works neither with enabled nor disabled)

I would expect that Visual C/C++ and x-86-64 should have a uint64 data type.

What do I need to set or do so that the type conversion works and C (or C++) code is created successfully?

Best

I found the answer to my own problem. I have referenced Models in my Project, and it seems that the Code Gereration has to be configured for each referenced model individually. Setting "Hardware Implementation - Advanced Settings - Support long long" to true in all Referenced Models did the trick. I had done this only on the "main" model, not the referenced models.
