I’m a beginner for RTOS concept. I was buy two book which was written by Mr.Richard Barry and i read it. Now i want to start with RTOS Microchip 18F452.
1.i make a new project at MPLAB with project wizard.
2.i am copy very simple code at MCC18\example\getting_started\program1\main.c to my directory and include it.
3.i am copy the files which they are founded at FreeRTOSV5.3.0\Source directory. These files are croutine.c, list.c, list.o, queue.c, queue.o, task.c, task.o. (Question 1: the object files are required, or C files are sufficent?)
4.i am copy the files which they are founded at FreeRTOSV5.3.0\Source\include directory. These files are croutine.h, FreeRTOS.h, list.h, portable.h, projdefs.h, queue.h, semphr.h, StackMacros.h, task.h. (Question 2: All of these files are necessary? Or when am i use this files, when not use?)
5.i am copy the files which they are founded at FreeRTOSV5.3.0\Source\portable\MPLAB\PIC18F directory. These files are port.c, port.o, portmacro.h.(Question 2: Object and header files are necessary?)
6.i am copy FreeRTOSCnfig.h file from FreeRTOSV5.3.0\Demo\PIC18_MPLAB directory.
7.Compile my project. And this is te error.

What is the wrong? At FreeRTOS book, only port.c, list.c and queue.c, task.c files are enough. Could you please explain me! I read the FreeRTOS book many times. But i don’t make a simple project. I am beginner. I’m sorry.
