The issue you're encountering arises from gmake searching for a library folder in an incorrect location. The "libraries" folder is located within the "aCLI/user" directory, with the full path being:
“C:/ProgramData/MATLAB/SupportPackages/R2024b/aCLI/user/libraries”
As the “Simulink library for Arduino Liquid Crystal Display” add-on is only compatible for R2018a to R2019a, as mentioned on the add-ons page, a modification is needed for it to work in R2024b. This involves editing the “LCD.m” file located at:
“C:\Users\<username>\AppData\Roaming\MathWorks\MATLAB Add-Ons\Collections\Simulink library for Arduino Liquid Crystal Display\Arduino_LCD_Driver\+LiquidCrystalDisplay\+block”
Please update line 85 of the file by modifying the “fullfile” function to include "user" folder, as follows:
libpath = fullfile(codertarget.arduinobase.internal.getArduinoIDERoot('libraries'), 'user', 'libraries','LiquidCrystal');
Additionally, please delete the folders generated by Simulink during code generation, specifically “lcdsimpletext_ert_rtw” and “slprj”. Removing these folders should allow Simulink to generate the code without any errors.
Alternatively, you can follow this official MathWorks documentation to create an LCD Add-on for Arduino when using later releases.
Hope this helps!
Thanks
