SIT - Simulation Interface Toolkit - build DLL

[Mehlsack]

Moin, Moin, (-> HELLO) ....

I want to build a .DLL from a Simulink model. The goal is to great a stand-alone tool, with a User Interface from LabView and a Numerical is based on a SIMULINK-model.

I used the Real Time Workshop to build a DLL from the SIMULINK with "nidll.tlc". But it doesn't work. I try it at two different computers (Systems).

Do anyone know, why it doesn't work?

System 1:

        Matlab Simulink 7.1 (R14) SP3

        Simulation Tool Kit 2.02

        LabView 7.1

        Microsoft Visual C/C++ version 5.0 in C:\Programme\DevStudio

System 2:

        Matlab Simulink 7.0 (R14) SP2

        Simulation Tool Kit 2.02

        LabView 7.1

        Microsoft Visual C/C++ 7.1

Replay System 1:

Mehlsack, try downloading the SIT upgrade 2.0.3 patch because some bugs have been fixed and your error may be one of them. Also, have a look at this thread to see if any other of those suggestions might help you: https://forums.ni.com/t5/LabVIEW/Why-can-t-Real-Time-Workshop-create-a-model-DLL/m-p/163797

Which parameter settings did you have in Simulink?

Thanks for the help...

With SIT 2.0.3 the error-messages are the same (Until know I tested only system 1). My Simulink settings are:

Solver: ode3 or ode4, "fixed-step"

System target file: nidll.tlc

Ups - I send the message by mistake, here are the rest of my simulink parameters

System target file: nidll.tlc

Language: C

TLC options: none

Hi,
check the environment variable settings (right click on "My Computer" - Advanced Tab - Environment Variables):
MSDevDir=<path to compiler>\Common\MSDev98 for Visual C/C++ 6.0 or something like that...

I'm not very familiar with Matlab R14 and SIT 2.0.x (my combination was Matlab R13 / SIT 2.0.x and Matlab R14/ SIT3), but check the settings within the simulation parameters one more time. For this, i've attached a screenshot!

Good luck!

The system 1 with Visual C++ 5.0 doesn't work, BUT with the new version of the SIT 2.0.3 the system 2 (Visual .net 2003) building some .lib files but it stopped before building any DLL. Now some linkage are wrong. The  path of MSDevDir is: C:\Programme\DevStudio\SharedIDE (both systems are equal).

System 1:

        Matlab Simulink 7.1 (R14) SP3

        Simulation Tool Kit 2.03

        LabView 7.1

        Microsoft Visual C/C++ version 5.0

System 2:

        Matlab Simulink 7.0 (R14) SP2

        Simulation Tool Kit 2.03

        LabView 7.1

        Microsoft Visual C/C++ 7.1

The error message of the system 2 is now:

## SIT 2.0 Generated Ports Readme file

The following make variables are used in the template make file, but they are not defined.
You may have a mismatch between the system target file and the template make file.

Hi,

i will setup a system with .NET, LV7.1, SIT 2.0.3 and R14SP1
I come back to you asap.

Regards,
ThSa

The solution:

the versions are not compatible !!!

I need SIT 3.0 for Matlab 7.1.

Now I using Matlab 6.5, which is working with SIT 2.0.3
