error: variable ‘task’ has initializer but incomplete type

[jdksiliconvalley]

Hi everyone,

I am new to Linux driver development. I am trying to build a keyboard driver that I found from the internet on Ubuntu 11.04 (2.6.38-12-generic). But I ran into the following error:

error: variable ‘task’ has initializer but incomplete type

Can anyone give me some suggestion what could be wrong?

Attached is the g-zipped archive (TestDriver.tar.gz) which contains KeyBoardIrq.dc and Makefile for your reference.

Thank you very much,
Jew-Dong
