I'm getting errors on te build process for Raspberry Pi 3 for a model that implements drivers for the Navio2 https://emlid.com/navio/ board. I implemented the model using drivers written in C++, and interface with MATLAB/Simulink using the matlab system object https://www.mathworks.com/help/supportpkg/raspberrypi/device-driver-blocks.html.
The problem is: when I run the original model, I get no errors. But, when I use the model as referenced by another one, I get the following errors:
FIrst, I tried to generate C code (even with the drivers being written in C++), and got this:
---
Error executing command "touch -c /home/pi/slprj/ert/Navio2Sensors/*.*;make -f Navio2Sensors.mk all -C /home/pi/slprj/ert/Navio2Sensors". Details:

compilation terminated.

Then, I tried to generate C++ code and got this:

I've found a solution to the problem. I've cleaned all MATLAB-generated files in Raspberry Pi, and then all worked fine.

@Nurul Farhana Mohd Fadzli In my experience, Matlab/Simulink sometimes get lost with the cache files and fails to update cache files for models that have been modified. So, in general, I always delete the contents of the cache folder and generated code folder in case I'm getting code generation/compilation errors.
