hi there: i got a problem about linking between simulink and dspace.My matlab version is 08b,and dspace is 6.5 release.using carsim8.02 to send a s-function to simulink,it works well,but when i build the model and download the simulink model to the dspace board,it turns out an error,here is the last few setences:

Hi Harvey,
Usually linking errors are a result of all or some of the required files not being accessible. In your case, the "Undefined Reference" indicates that the process cannot locate a file. Please organize all necessary files for your S-function to the build path or MATLAB directory.
For more information on best practices in dealing with S-functions for dSPACE systems go to the link below:
