Thread Subject: Compiling error with Level-1 M-File

Hi,

I wrote a simple Level-1 M-File S-Functions, which I included in a
Simulink Diagram, and I tried to compile it with the Simulink Diagram
with RTWinTgt (Real-Time Windows Target) Toolbox Version 2.6
(R14SP3). I have used the rtwin.tlc System Target File, for the RTW
configuration.

The RTW gives a error in File: utillib.tlc Line: 403 Column: 8, and
in the Matlab Command Line prints the information about the TLC
Function Traceback.

I found that the error are generated by the File: simple_example.m
Line: 18 Column: 24. The change of the value of the sizes.NumOutputs
variable to 0, will produce no error in the compiling time. But with
this change the diagram lose the posibility to output the variable
and also gains some warnings.

sizes.NumOutputs = 0;

Please, Do you have some advice to solve this error correctly? Maybe,
I have to modify the RTWinTgt TLC Files, to make that the TLC files
work properly.

Regards,
Pedro Villena

Do you have a tlc file with the same name as your Sfunction but with .tlc
extension?

I made this question, by the cause of a previous test that I had made
with a Level-1 M-File S-Function only with a input signal (see
example_input.m), and I hadn't needed a TLC-File for to compile this
test with rtWinTgt (rtwin.tlc + rtwin.tmf).

So, if I need a TLC-File for a Level-1 M-File S-Function with a
output signal (s_ex.m + s_ex.tlc). Could you send me an example? I
saw every example in the MatLab Help and Documentation and read all
the documentation of RTWinTgt Toolbox, and I didn't found a example
with these characteristics (Level-1 M-File S-Function + TLC-File).

Pedro Villena

Hi,I met the same problem now.
Have you had any solutions to this?
Or we can just rewrite a C-Mex file S-function and then
create a tlc file for it.

you can send me an email for discussing this.

Thanks
