compilation error with LEGO EV3

I'm trying to execute Simulink with LEGO EV3, but with the example, when I click the Deploy to Hardware button, I have a error:

:

"### Creating standalone executable "../untitled" ..." C:\ProgramData\MATLAB\SupportPackages\R2017a\3P.instrset\ev3sourcerylite.instrset\CodeSourcery\bin/arm-none-linux-gnueabi-gcc -lrt -lpthread -LC:\ProgramData\MATLAB\SupportPackages\R2017a\3P.instrset\ev3sourcerylite.instrset\CodeSourcery\arm-none-linux-gnueabi\libc\lib -o ../untitled untitled.o linuxinitialize.o driver_ev3_button.o driver_ev3_lcd.o MW_legoev3init.o ert_main.o -lm -lm

linuxinitialize.c:(.text+0x7c8): undefined reference to `backgroundTask'

collect2: ld returned 1 exit status

gmake: *** [../untitled] Error 1

I'm using Matlab 2017a, and I installed the Matlab LEGO Minstorms EV3 and Simulink LEGO Minstorms EV3, and Embedded Coder Cortex-A toolboxes.
