PCI controller rs232 Moschip 9865, error install driver

I have a PCI Controller Moschip 9865 (2xRS232 and 1 parallel port). I downloaded the source code for the driver. Driver is compiled on another computer. I downloaded the kernel source 2.6.32-17, copied. Config file from my server and compiled the driver. But printing error, please help how to fix it.
