Problem with lirc_gpio

[David G. M. <dm...@me...>]

Hi.
I'm new in lirc.
I can compile lirc to use it with my tv card receiveir (bestbuy easytv), but 
when I execute the insmod command in order to load the driver I obtain the 
next messages:

/lib/modules/2.4.9-13/misc/lirc_gpio.o: unresolved symbol

Can anybody help me?


Another question:
I tried to make a serial receiver using an Is1u60, but I don't know how I 
have to connect it with the serial port.
Where can I obtain a diagram?


Thanks.

PD: Sorry for my poor English.
