How to distribute NIOS II drives and librarys

Hi all,

i have written many device drivers and a software package for the NIOS II Processor. Now i am going to deliver a FPGA-System to a customer. The customer needs to be able to write his own C-Programms for the NIOS II Processors running on the FPGA. He also needs the drivers an the SW-Package i have written.

Is there a way to generate a lib wich includes all my files as obj-code or smthg, so that the customer cant see the code i have written in c (Header files are no problem, but he should not see the c-files)?

Thanks,
