Call C Functions Using C Caller Block analyzing code indefinitely

Hi,

I am trying to port some c code for my dsPIC33EV dev board I have to run CAN using Simulink.

When I click on the C caller block it says that it is analyzing my .c file but it carries on forever and never finishes, does anyone know why this is happening?

Also if anyone has any experiance with this board/chipset and making working can blocks for Simulink then I would really appreciate some help.

Thank You!
