I recently started using plecs on macos. I have my simulation files originally in a windows computer. I am working on co-simulation between code file written and saved in the same folder as the PLECS simulation file. In windows machine I was able to easily run simulations. But when I export the same simulation files onto my macbook, the C-Script returns a compilation error saying it couldnt find the rpc.h file that one of my files included. Can you tell me how to solve this?
