Get Error "RTW.genMakefileAndBuild at 937" while RTI procedure is running

Hi there,

I got a real big problem. I worked with Dymola v. 6.1,
Matlab R2007a and dSPACE DS1006 board.

I create a small Dymola Modell an build the s-function in
Simulink. That works well, but if I choose in the Dymola
Modell that the Option "Evaluate parameter to reduce
modells" Experiment setup\translation. I didn't get the
inner parameters in the s-function. That is the second
problem with the Interface between Dymola and Matlab.

To compile this modell it works fine, the *.mdl file is
created and I get correct values after the simulation in

Now I like to build the *.sdf file to run this modell at the
dSPACE expansion box. But the Compiler stops and I get the
following Message:

Error building Real-Time Workshop target for block diagram
'Simulink_Test'. MATLAB error message:
Error using ==> RTW.genMakefileAndBuild at 937
*** Make process failed while compiling, linking, or loading
*** Detailed error messages are printed in the MATLAB
Command Window

This is shown in the command window:

NOTE: The following option in the Configuration Parameters
dialog has been

"Conditional input branch execution" On

This leads to code optimization in which blocks are
not computed if their
outputs are not required in the simulation step, for
example, if their
output values are used as input for a Switch block and
the Switch
currently routes another signal. When the
corresponding output signals
are displayed in ControlDesk, their values are static.

To ensure that the blocks are computed, turn off the
"Conditional input branch execution" option and
rebuild the model.

*** Stopped RTI build procedure

Please could someone tell me what is wrong to comile clean
Simulink modells it works without any errors, but if I like
to use s-function it doesn'nt do this.

I have read th bug reports

and I have done these to workarounds:

Thank you for your great help and advanced
