MATLAB: Do I receive errors when trying to build the model which has a CAN PCI I/O board using xPC Target 1.1 (R12)

Why do I receive errors when trying to build my model which has a CAN PCI I/O board using xPC Target 1.1 (R12)?
When I try to build my model using the xpctarget.tlc system target file, I receive the following errors:

XPCTEST runs fine, but I still see the above errors.

Best Answer

The reason you are receiving these errors is because you are not defining the CAN library to be used. If you go to the xpcsetup GUI you will notice that the "CANLibrary" field is specified as "None". Please select an appropriate library to your CAN and then try building your model. Be sure to update the model (by pressing Ctrl+D) before building it.
You can open the xpcsetup GUI by typing 'xpcsetup' at the MATLAB command prompt.
