Hello everyone;
I'm making a S-function block, with the code from Arduino.
I tested the code from Arduino and it works fine, but when I made the S-function builder I receive this error:
Ons/TOOLBO~1/EMBEDD~1/code/ENERGI~1/@SLCUS~1/../SCHEDU~1/include -IC:/Users/Alberto/DOCUME~1/MATLAB/Add-Ons/TOOLBO~1/EMBEDD~1/code/COMMON~1/include -o "Prueba_wrapper.o" "../Prueba_wrapper.cpp"
