When I have generated the code and update the grt_shell.c file for inputs and outputs I tried to build the DLL as mentioned in the section 4.6. when I execute the command gmake –f ($NAMEOFMODEL).mk I am getting an error “:128: *** missing separator. Stop.”.
I understand that this is caused due to the use of space in place of tabs. But as you might know the .mk file is generated by the RTW. I checked the line 128 in the .mk file and it has no space at all.
