I encountered a problem working with the EMWIN package in keil, this error message:

. \ Objects \ test.axf: Error: L6218E: Undefined symbol LCD_X_Config (referenced from C: \ Keil_v5 \ ARM \ PACK \ Keil \ MDK-Middleware \ 6.2.0 \ emWin \ Lib \ ARM \ GUI_CM3_L.lib (gui_core.o ))

Application code is available at the following link:


you can see the error here:

Undefined symbol LCD_X_Config

Please give guidance if possible. Thanks
