Thread Subject: Building in Real-Time Workshop

I am trying to build a model in Real-Time workshop with an s-function in it. When I do, I get a large amount of errors saying that things have been declared multiple times. It has to do with the files rt_mxclassid.h, matrix.h and rt_matrx.h. They all seem to want to declare the same things over and over. A sample of the errors can be found below. Does anyone know what may cause this or how to get the model to build?

Which headers do you include in your S-function? Recompile with
<simstruc.h> only. Otherwise, you have to provide more information,
that is source code and full compilation log.

I compiled only with simstruc.h and I still get the same errors. The s-function I am trying to compile is a piece of freeware called TrueTime meant to simulate a computer network in simulink. I have modified it to run in a fixed step rather than variable so that Real-Time Workshop can work with it. The code itself is far too large to post here. I can mex the code and place it in a s-function block in simulink. I can even run the code in simulink with no problems and it functions perfectly. When I try to build it in Real-Time workshop, however, I get those errors I posted previously. This only happens once Real-Time Workshop begins trying to make the executable. Those are pretty much all of the errors I get. Although there are many more than I posted, they are all the same with just the variable name changed. The two different files seem to be declaring them one after another
and causing an error. If you could offer any suggestion on what may be wrong or how to go about debugging my code that would be very, very appreciated.

Thank you,

-Eric

Hello Eric,

I had a glimpse on ttkernel.cpp and there are some constructs in it that
will never work with a standalone RTW executable without redesign of the
code base. For example, definition of Matlab workspace variables from
within the MEX file. Looks as if you can't get what you want easily.
