Minseg hardware simulink deployment - "failed to generate binary" error

I am trying to deploy a very simple model using simulink to my minseg device (Arduino Mega 2560) and I keep getting an error that states: "Error(s) encountered while building "Minseg_test_1": ### Failed to generate all binary outputs."

Here is the model:

And the full diagnostic code:

Sometimes Simulink cannot handle spaces in directory names. I don't know why they didn't fix that long ago.

There is probably some file that can be edited to fix the problem, but I do not have that MATLAB or Simulink (or MS Windows to experiment on.) The work-around that I know would work would be to install MATLAB in a path that had no spaces in the directory name.

I tried your suggestions. I even reinstalled Matlab into a folder that had no spaces. I took out all the spaces in any folder that was a parent folder to where my simulink file is. I think that may have solved some problems but it still isn't working. The error I get now is:

IC:/Matlab/supportpackages/R2015b/arduino/toolbox/target/supportpackages/arduinotarget/registry/../scheduler/include -o "Minseg_test_1.o" "Minseg_test_1.c" 
arm-none-eabi-gcc: error: unrecognized command line option '-mmcu=atmega2560' 
gmake: *** [Minseg_test_1.o] Error 1

I find some hints that that toolchain is too old to support mega2560.

At the MATLAB command prompt, give the command

targetinstaller

and use that to select a Simulink support package for mega2560
