Compilation due

Hi everyone! please I need help, I work on the multitask with the Freertos library and the arduino DUE card. My problem lies in the compilation of freertos example programs, with the arduino card due I receive an error message: fatal error: avr / io.h: no such file or directory ... I do not understand not this error message and I would like you to help me to solve

The 'avr' in that message indicates that the FreeRtos that you use is for the AVR line of Arduinos (Uno, Leonardo, Mega).

Try to find one for the Due.
