I have an STM32373C Evaluation Board. Recently I downloaded CubeIDE and tried the 'Hello_world' exapmle program and the TFT_LCD works fine. However, I made my own project where I included all the header files which were needed (e.g GUI.h etc..) and in my project all the functions works fine except for LCD related functions. I attached a picture, which shows the error. It is some sort of building error, but I dont know which setting should be used when I build it. Any ideas what is wrong with it?
