grt.tlc compiling error

Question

0 个投票

Hi,

I created a mdl model that runs fine but, while compiling (grt.tlc), I get the error as at the end of the message. I know the error is caused by an embedded matlab function but I can't solve the problem because is completely unlogical to me. In particular, in my model I have two identical subsystems (that simulate airplanes) in the root system. If I delete one of them, the model compiles fine. If I replicate the airplane-subsystem I get the error below (while it still can run). Inside the air-subsystems there is an embedded matlab function. The code lines that seem to cause the problem are:

coder.varsize('StructAirOthers', [10 1]);
StructAirOthers = struct('P', zeros(3,1), 'Vel', zeros(3,1));
for i=1:n (n<=10)
StructAirOthers(i).P = ...
StructAirOthers(i).Vel = 
end

followed by a loop that dynamically fills the array of structs. By removing the use of this struct inside one of the embedded matlab function (no need to remove it in both) it compiles fine. In addition,the cause it is not the coder.varsize istruction as the sole struct() function is enough to cause the issue. I am really frustrated because of this problem.

Thanks,

Alessandro
